Gas-liquid-dual-purpose safety valve discharge capacity test device and test method

Abstract

The invention provides a gas-liquid-dual-purpose safety valve discharge capacity test device. Another technical scheme is that the invention provides a gas safety valve discharge capacity test method based on the gas-liquid-dual-purpose safety valve discharge capacity test device. Another technical scheme is that the invention provides a liquid safety valve discharge capacity test method based on the gas-liquid-dual-purpose safety valve discharge capacity test device. Liquid and air safety valve discharge capacity test benches are combined organically, and a corresponding operation process flow is specially made for a safety valve test system, thereby effectively saving construction land, device investment and maintenance cost and the like.

Description

technical field [0001] The invention relates to a test device for the discharge capacity of a gas-liquid dual-purpose safety valve. Background technique [0002] The safety valve is the last overpressure protection device of the pressure system, and is the main safety accessory on the boiler, pressure vessel and pressure pipeline. In order to effectively reduce the internal pressure of the pressurized system, it is necessary to ensure that the safety valve has sufficient discharge capacity when it is overpressured. All safety valve series must pass flow tests during the research and development process to ensure that they meet the standard requirements. [0003] The current safety valves can be divided into liquid safety valves and gas safety valves according to the applicable medium. The displacement coefficient of the liquid safety valve needs to be tested on the liquid safety valve test bench, and the gas safety valve needs to be tested on the gas safety valve test bench...

Problems solved by technology

This will cause a lot of unnecessary waste: 1. The two sets of test benches need to open up the space required for the two test benches respectively, and they cannot interfere with each other, resulting in waste of land occupation and construction; 2. Construction of two sets For the test bench, two sets of equipment such as pressure vessels or compressors that can be used in general must also be purchased, which causes
