check valve
(OP)
Hi,
Hi All. I am interested in reverse engineering of solenoid valve.Please anyone throw light on solving the follwing problems
In Poppet type check valve how to determine dimension, the distance the poppet rises out of its seat.I am intersted in calculating correct amount of lift for aerospace application.
And i have one more question,how to calculate orifice diameter.As i am having details of flow upstream pressure,pressure drop,leakage rate
thanks in before
John

RE: check valve
It will be more logical if you can give more information as:
Gas Pressure
Flow rates
Gas type
Supply voltage
Maximum current available
Type of valve (2 ways, three ways, ON-OFF etc.)
Dimensions
Actuator load or torque requirements
Piston area and travel
External loads and inertia
Environment
and more.
RE: check valve
I did orifice design calculation by using continuity equation & Bernoulis equation.Is there any other method to find orifice parameters analyticaly
Folowing are the details
operating pressure: 3100Psig
Flow rate : 1.5Gpm @ 300Psid
Fluid density : .00008 lbf^2/in^4
Supply Voltage : 18-30 VDC
Max current availabilty : 0.5Amps Max @ 28Volts
Type of valve : ON-OFF
Thanks in before
