Abstract

The invention belongs to the technical field of valve tests, and discloses a valve impact performance test pipeline and system. The system comprises a mechanical system and a measurement and control system, the mechanical system is used for providing a gas medium and working conditions for a tested piece, and the measurement and control system is used for controlling the gas medium and the working conditions and automatically collecting and storing test parameters. The mechanical system comprises a gas pressurizing unit, a high-pressure gas cylinder unit, a pressure reducing valve mounting unit, a gas cushion simulation unit and a flow adjusting unit; the gas pressurizing unit is used for pressurizing a gas medium; the high-pressure gas cylinder unit is used for storing and releasing a gas medium; the pressure reducing valve mounting unit is used for clamping and fixing a tested valve; the air cushion simulation unit is used for simulating the volume change of a pipeline behind the tested valve; the flow simulation unit is used for simulating working conditions when the valve flows are different.

Description

technical field [0001] The invention belongs to the technical field of valve testing, and in particular relates to a valve impact performance testing pipeline and system. Background technique [0002] In the conventional valve test system, the usual way to adjust the volume of the cavity after the test piece is: fill the water tank with water, control the water filling volume of the water tank, and use the remaining volume in the water tank as the simulated air cushion volume. The disadvantages of this method are: : 1) The system needs to increase the water medium subsystem, and the water supply and drainage of the container need to be considered, and the system is relatively complicated; 2) The volume control is realized by liquid level control, and the accuracy is low; 3) The follow-up pipeline of the simulated air cushion has a Larger water vapor has come, affecting the accuracy and life of the system, causing potential safety hazards; 4) The volume occupied is relatively...
