Description
Technical field
The present invention relates to a kind of gas delivering pipe system pressure experimental device.
Background technology
At present, the strength test technique of known liquefied natural gas and natural gas high pressure pipe-line system is all to be come as test(ing) medium by water or dry air, but it is the longest with water for the dry run that test(ing) medium is follow-up, and be difficult to remove intrasystem water completely, equipment component needs isolation at the trial.Doing experiment with dry air higher to air quality requirements, and high test pressures (25.5 Mpa) needs the system that large-scale compressor and auxiliary device, especially volume are bigger, the requirement to equipment is the most more.For system complex, the system test difficulty that welding valve member is many is the biggest.
Therefore, the technology of a kind of improvement it is badly in need of to solve this problem in the presence of prior art.

Described cryogenic liquid pump is provided with relief valve I.
Pipe between described cryogenic liquid tank and cryogenic liquid pump is provided with relief valve II and low temperature major axis stop valve, and described relief valve II is near cryogenic liquid tank end, and described low temperature major axis stop valve is near cryogenic liquid pump end.
Pipe between described gas returning port and cryogenic liquid pump is provided with relief valve IV and cryogenic globe valve III, and described relief valve IV is near gas returning port end, and described cryogenic globe valve III is near cryogenic liquid pump end.
Pipe between described air-heating type gasifier and cryogenic liquid pump is provided with high-pressure check valve and cryogenic globe valve I, and described high-pressure check valve is near cryogenic liquid pump end, and described cryogenic globe valve I is near air-heating type gasifier end.
Described air-heating type gasifier and be sequentially provided with Pressure gauge, relief valve III, cryogenic globe valve II, high temperature break valve I and high temperature break valve II with on the pipe between gas point, the pipe of described cryogenic globe valve II and high temperature break valve I connects cryogenic liquid pump by superpressure temperature interlock.
The invention have the advantage that the high-potting of completion system in the short time, experimental safe is high, can carry out tightness test the most again, shortens the test period, cost-effective.
