Help analyze the reasons for the rupture of the pressure reducing valve valve diaphragm
Thread Content
The balance diaphragm of the PSA exhaust gas pressure reducing valve (Hocod brand) is broken. The valve inlet pressure changes periodically between 0.8 and 0.2 bar. The pressure behind the valve is set to 180 mbar. The new valve has only been used for half a month.……
It should be that the production equipment has just been put into use.
The cracking does not appear to be caused by improper use, but appears to be caused by instability on one side.
It should be that the pressure was exceeded in the early stages of construction.
Haha, at first glance, it looks like a weak thing. Check similar valves of other structures, or self-operated regulating valves.
Adjust the curve to see if there is overpressure.；
