Using pressurization is stopped when pressure, wait for 3~5 minutes；
5）After all going well, continue to be forced into test pressure as defined in valve, pressurize is carried out by the regulation dwell time, and
Carrying out comprehensive double check, whether there is or not breakthroughs；
6）When determine single unit system without decompression and valve No leakage to be checked, after reaching the dwell time, pressure is dropped into valve
Use pressure, wait for 3~after five minutes again all discharge pressure and water；
7）Valve to be checked is dismantled, detection terminates.
The utility model is used on equipment principle and technique in storage pressure pipe and valve installation process to be checked, different
The unit integrated morphology that specification framework is formed, by specification composition different series configuration, all using mesohigh accessory, to each main
Cellular construction carries out integrated combination, and with flanged joint, so that replacing or installing valve, operation is simple, reaches high leakproofness
Can, saving of work and time is small, light-weight, convenient transportation.
