IRJET- A Review of Design and Analysis of Retainerless Dual Plate Check Valve for Reduce Pressure Loss and Drag Force
0 likes•81 views
This document reviews the design and analysis of a retainerless dual plate check valve to reduce pressure loss and drag force. It discusses how modifications to the valve disc geometry can reduce the impact force when closing. Computational fluid dynamics (CFD) is used to evaluate the pressure loss coefficient and drag force coefficient at various openings and Reynolds numbers. The dual plate check valve is found to have lower pressure loss and drag force coefficients than other check valve designs. Finite element analysis is also used to analyze stress and deformation of valve components. The goal of improving the design is to reduce pressure loss and drag force for improved efficiency.

Abstract - When a dual plate check valve closes then many
problems find out like noise, vibration and seat wear. Reduced
the impact force between the valve disc and its seat when
closing some modifications is applied to the valve disc
geometry to reduce the drag force acting on it. The value of
pressure loss coefficient (cp) and drag force coefficient (cd)
has been evaluated at various openings and Reynoldsnumber.
It has observed that valve of pressure loss coefficient (cp) and
drag force coefficient (cd) lower in case of dual plate check
valve.Using ASME standardsfordualplatecheck valvesbodyis
categorized as a pressure vessel that contains only internal
pressure. This verifies the validity of the CFD results an
approximation of the disc rotation characteristics is given,
based on the CFD approaches this approximation method is
verified on another check valve simulation with different
boundary condition and external moments. The design will
carried out for cracking pressure, coefficient of valve and
equivalent stress. It has been found that are safe stress limit of
the material used.CFD module of Ansys 16.0 will used for
finding out the pressure loss (cp), drag force (cd) ,flow rate of
the valve.
Key Words: dual plate check valve, retainerlesscheck valve,
pressure loss, drag force, pin of check valve, Reynolds
number.
1.INTRODUCTION
A valve gadgets that regulate, direct or control the flow of a
fluid (gases, beverages, fluidized solids, or slurries) via
beginning, last, or partly obstruct variety ways. Valves is
mechanically fittings, but it's generally discuss as a divide
types. The open valve situation, fluid flow way upper
pressure to lower pressure. valve phrase is original fromthe
Latin valve, the variable a part of a door in flip from volvere.
The handiest, also really historic, valve be actually a
generously hinged wave which dropstowardsimpedeliquid
(gasoline and fluid) flow in one route, other than driven
open through go with flowwithinthecontrarydirection.that
is referred to as a test valve, because it's prevents thefloatin
single pathway. recent controls valves might also float or
control pressure downstream perform on difficult
automation systems. [1]
The Valve is many makes use of, consisting of controlling
water for irrigation, business makes use of for controlling
procedures, residential makes use of like on-off, pressure
manipulate to dish or garments washer and tap into the
domestic. Even aerosol is a little valve in constructed.Valves
also that use inside navy as well delivery sectors.
The dual plate take a look at valve is a swing valve uniquely
designed for all reason non return valve (NRV) packages.
The constructional feature makes the valve a whole lot
smaller in length, lighter in weight & makesitlotspossible in
operation in comparisontoconventional swingtakea lookat
valve.The dual plate swing take a look at valve employ dual
spiral overloaded plates / disc hinged at a principal hinge
pine. It operates on the differential pressure between fluid
drift pressure & spring torsion pressure. because the flow
pressure reduces, the plates tends to close with a cushion
impact by spring torsion pressure there by limiting the
reversal of fluid flow.

2. LITERATURE SURVEY
Literature survey is an evaluated report of information
found in the literaturerelatedtoselectedareaofstudy.Inthis
chapter literature survey of valve, pressure loss, drag forces,
fluid and it density, openandclosepositionofcheckvalvehas
carried out.
This study purposeful on theory of optimum, using the
gradient technique. In investigational element the method
createmesh and geometry through the followingmeaningof
a numerical model calculated for the model computation of
flow in dual platecheck valve. Boundary condition are justof
the subsequent variety shell, inlet pressure, outlet
pressure,rotating and translational periodic situation. [2]
The pressuredrop featuresoftwotypeofdualplatecheck
valve swing plate and dual disc check valve have analyzed
through CFDundervaryingconditionsofoperations.TheCFD
software ansys fluent has used. The dual plate check valve
inner diameter is 0.05, valve length 0.25mand lengthofduck
0.75 m and they have got pressure loss coefficient (cp)
,coefficient of drag(cd),permanents pressureloss co efficient
has been valuation at various openings and Reynolds
number. [3]
The measurement of dynamic characteristics of check
valve. The force had stopped as of the special steady flow
rate. It has also visible the upper deceleration upper
overturn velocity develop previous to the check valve close.
via Time-pressureprocess, suitablemathematicalmethod.[4]
They have studied parameter of Pressure loss, Length of
passage, width of the passage, plate thickness, fluid and its
density. Validated CFD methodology has used to analyses
flow through the dual disc check valve and butterfly valve.
here keeping conditions is inlet velocity 2m/s and diameter
of pipe 20 mm By keeping Reynoldsnumber1000and50000,
valve opening angle like 10,20,30,40,50,60,70,80,90
variables data on the variations in Pressure loss coefficient
(CP) 0.97 and drag coefficient (CD) 3.228 at 1000 re and 90’s
angle decreases with increment in both Reynolds number
and valve opening angle for dual plate check valve and
butterfly valve. [5]
The document also present the opinion on design of the
check valve and analysis of the Spring acting main role in
definite cracking pressure and it is also failure, due to shear
by apply compression load. The cracking pressure and
coefficient of valve by testingare 0.035-0.045 and 0.652MPa
respectively.which are very close to the theoretical values.
Various simulations, numerical and boundary conditions in
FEM using method and get equivalent stress of 418.736 MPa
and deformation of 13 mm. [6]
This paper expanded on thetransientstudyofadualplate
check valve during the opening time.Thecharacteristicofthe
pressure drop across the check valve is highly correlated to
the velocity per unit area at the minimum cross section. Due
to the small gaps between the discs and the valve seat, the
disc will not move until the inlet velocity grows to some
certain value,causing a local peak point pressuredropcurve.
Pressure dropping by seat. [7]
The input data for hub end valve was referred from API
594, API 598, ASME B16.5,ASMEB16.34standardhavebeen
used for generating starting the design for the valve.FEA
module of the Solid works software has been used for the
design of components of the valve with validationThedesign
has been checked for stresses, strain & displacement for
rating of 2500. It has been found that are in the safe stress
limit of the material used. then flow rate of valve is 0.0769
(m3/sec).CFD module of Solidworks has been used to find
flow rate of valve and its flow coefficient (Cv). [8]
When a check valve closes, itsdiscslamsonthevalveseat,
this slam may cause many problemslike noise, vibration and
seat wear. Also the modified valve disc shows a good
performance concerning valve flow coefficient at normal
operating conditions when the disc is fully opened at 75°
where the flow coefficient for the modified valve plate is
almost the similar as the original valve disc (0.44 % lower).it
is comparison between the result of original and modified
valve disc model. Using by solidworks flow simulation. [9]
The objective of this paper is to perform analysis and
optimization of the critical component of Check Valve, its
Body or Housing. The critical design analysis of stress
development using 3D CAD models of check valve housing
and finite element engineering simulation of various stress
and deformation tests at pressure class 600,size of the valve
10” inch and working allowable maximum pressure 10 MPa
in Ansys v14.5. [10]
The study of a variety of creativewritingitseemthedepth
of cut ,feed type or geometry of tool or inserts are the most
important parameter which have an effect on geometrical
characteristics of work piece as flatness in milling machine.
The various levels along with its range are also studied. Our
attempt is to apply DOE to achieve desired flatness and
predict the flatness fordualplatecheckvalve.Themodelmay
helps to predict the response of the output parameter. The
weather quality/geometry lies within desiredtolerancelevel
and find the responsible factors, which are mainly affecting
the geometry of work piece like flatness, straightness. [11]
The parameter are minimum valve angle 2.51, maximum
valve angle 60, diameter of plate 410 mm, inner diameter of
pipe 378 mm, radius to centre of gravity 247.3 mm, moment
of inertia 2.987, seat area 0.1122 m2 by using Finite
difference methods CFD. The force factor Ff as well the loss
factor kloc are evaluated by this CFD simulation for steady
flow and also for a transient flow with a gradient of 2.0
(m/s²) of the inlet velocity. The dynamic simulation of a
required counting of the relative motion of the fluid and disc.
[12]
The failures that were not due to improper seating were
due to the valve being either stuck open or stuck closed.](https://image.slidesharecdn.com/irjet-v6i5297-190907051000/85/IRJET-A-Review-of-Design-and-Analysis-of-Retainerless-Dual-Plate-Check-Valve-for-Reduce-Pressure-Loss-and-Drag-Force-2-320.jpg)

Failure area identifies the part of the valve that was affected,
resulting in failure. Hinge pin, including bushings, Disc stud,
Seat area, General wear such as damaged spring. [13]
That valve geometry affected the magnitude of pressure
surges and reversevelocities.Reversevelocitiesandpressure
surges are greater for valves with a larger mass of valve
components. Reverse velocities are greater for valves with
larger strokes or travel of components to close. Reverse
velocities are less for valves that were spring assisted to
close. Theseconclusionsarejustifiedbecauseoftheincreased
time necessary to accelerate and overcome the inertia of
valve internals and the distance they must travel. [14]
3. CONCLUSION
The literature survey has shown thatmanyresearchershave
successfully investigated the process parameteronflowrate
of valve, pressure loss, drag forces, fluid and it density, open
and close position of check valve. Dual plate check valve has
non-return valve so the main forced on the pressure loss,
drag force and flow rate by the disc angle, hinge pin andstop
pin. The dual plate check valve is analyzed and results were
obtained by varying the valve opening angles like
100,200,300,400,500,600,700,800,900and varying Reynolds
numbers. When the fluid flow is passed from the dual plate
check valve then angle of the disc various and disc are
quickly open and takes some more time to close compare to
open and possibility of leakage by top and bottom of hinge
pin due to pressure. Therefore, pressure loss is increases. It
has been found that the stresses, displacementandstrain for
structural of valve body at different size and its pressure
ratting. Pressure loss co efficient 0.97 and co efficient drag
force 3.228 at 1000 Reynolds number using inlet velocity 2
m/s and diameter of pipe 20 mm, models test in k-epsilon.
4. Future scope
To avoid mention problem we suggest new design
of spring, hinge pin, disc thickness. Analysis can
happen made from various positions of disc (plate)
and hinge pin and valve body for decrease pressure
loss co efficient and co efficient drag force.
This verifies the validity of the CFD results an
approximation of the disc rotation characteristicsis
given, based on the CFD approaches. For get
solution of analysis is found to use laminar, K-
epsilon, K-omega model, which will indicate the
flow rate or Reynolds numbers.
The static structural used for Equivalent Stress,
Equivalent Elastic Strain and Total Deformation.
Dual plate check valve made of API &ASME and
other standard so shall use new parts design also
base on that.
The design will check for pressure class rating 150
with in 6 inch because this pressure class is
between high and low range of class.
