What is the overpressure setting pressure of the safety valve, the trip pressure and the return pressure? What is the relationship between these two? Please help. I have a safety valve here which is HTO-Q1CC. The set pressure is 0.5MPa and the excess pressure is 0.515MPa. What should its return pressure\takeoff pressure etc. be?

The reliable way is to ask the valve manufacturer. Large valve manufacturers have technical calculations in this area. Be sure to ask the technicians, not the salespeople.
work pressure: It refers to the normal pressure that the valve body itself can withstand. Generally, it can withstand an instantaneous pressure greater than 1.25 times the nominal pressure. Set pressure: It is the valve opening pressure, that is, the safety valve will open when this pressure value is reached or exceeded. It is an artificially set value, but it should be within the working pressure. Takeoff pressure: It is the actual action pressure. seat back pressure: After the safety valve is discharged, its disc contacts the valve seat again, that is, the inlet static pressure when the opening height becomes zero:loveliness: (please point out if this is wrong) This post was last edited by 181128425 on 2009-4-10 17:45 ]
I don’t know what specific information the poster wants about the safety valve! Please suggest the specific name. Because there are many kinds of information about safety valves, it is difficult to upload!
Ha ha! The sound of the safety valve jumping is like the crow of a big rooster!
I don’t know what the size of the poster’s safety valve is? I have some catalogs of imported safety valves here!
Can it be sent to the mailbox? qjlmtyy@126.com or 60113962@qq.com thank you
