Abstract

The invention relates to an outflow safety valve function test set, comprising a vacuum pump, a height meter, a first exhaust valve, a first stop valve, a second stop valve, a third stop valve, a calibrator, a differential pressure meter, a height limiter, a metering valve and a second exhaust valve; the second stop valve and the calibrator are mounted sequentially on a main pipeline between the vacuum pump and the height meter. The outflow safety valve function test set has the advantages that a first exhaust valve connection and a second exhaust valve connection are provided to test two valves at the same time, test efficiency is improved, and the outflow safety valve function test set is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a function testing device for an outflow safety valve. Background technique [0002] By simulating the external pressure, the safety valve performs a functional test on the outflow safety valve to meet the requirements of the functional test, but its disadvantages are: high cost, long cycle and difficult maintenance, and the test process is cumbersome and the test efficiency is low. Contents of the invention [0003] In order to overcome the defects of the prior art, the invention provides a kind of outflow safety valve function testing device, the technical scheme of the invention is: [0004] Outflow safety valve function test device, including vacuum pump, altimeter, first exhaust valve, first stop valve, second stop valve, third stop valve, calibrator, differential pressure gauge, height limiter, metering valve and second Exhaust valve, on the main pipeline between the vacuum pump and the altimeter, a second shut-off val...
