Description
Technical field
The present invention relates to the assay device of the performance of safety valve of a set of gas liquid two purpose.
Background technology
Relief valve is last one overpressure protection apparatus of pressure bearing system, is main on boiler, pressure vessel, bearing pipe
Safety attachment.Therefore to ensure the quality of relief valve, all relief valve all must the property done in research and development and batch production process
Can test, to ensure that it meets standard-required.
Present relief valve divides according to Applicable media, can be divided into liquid safe valve and gas safety valve.And liquid peace
The performance of full valve needs liquid safe valve test bench location to go test, and gas safety valve needs gas safety valve test bench location to go
Test.This is the common situation of current all safety valve testing platform positions.And if a relief valve manufacturer produces two simultaneously
During the relief valve of type, also it is necessary for setting up liquid safe valve test bench location and gas safety valve testing table position respectively, so
Both occupy too much land area and too increase the cost of equipment construction.
Liquid safety valve test platform and the gaseous state safety valve test platform of present each relief valve producer are separately to build
If even some producer establishes the performance of safety valve test bench location that steam is special the most specially.But these test bench location
Function singleness.That is the test(ing) medium of air test platform position can only be compressed air；Liquid safe valve test bench location
Test(ing) medium can only be water.Two cover systems are incompatible.So will result in the most unnecessary waste: 1, two overlap test bench location
Need to hew out the place needed for two test bench location respectively, can not interfere, cause the waste in terms of occupation of land and building；
2, building two set test bench location, some equipment such as pressure vessel or compressor that originally can be general also must buy two sets,
So cause the waste of equipment；3, two test bench location are also required to safeguard respectively during one's term of military service, so also result in dimension
Protect the waste of cost；4, even will consider two set equipment power consumption simultaneously and water consumption in Factory Electricity Supply and water supply process, make
The waste that the capacity having become power supply water system increases and produces.
