Abstract

The invention discloses a system for detecting the sealing performance of emergency shut-off valves. The system comprises a test pipeline, a booster pump, a pressure release valve, a vent valve and apressure gauge, wherein a plurality of detecting stations are arranged on the test pipeline and are all used for installing the emergency shut-off valves; the booster pump is connected to a first endof the test pipeline; the pressure release valve is arranged on the first end of the test pipeline; the vent valve is connected to a second end of the test pipeline; and the pressure gauge is arrangedon the second end of the test pipeline. The system disclosed by the invention has the beneficial effects that a plurality of emergency shut-off valves are installed on the test pipeline, only one ofthe valves is opened at a time, a constant high pressure is set on one side of the valve and the pressure change of the other side is detected to judge whether the emergency shut-off valve in a closedstate meets the airtightness requirements or not; and therefore, the batch processing is realized and the detection efficiency is greatly increased.

Description

technical field [0001] The invention relates to the technical field of valve detection equipment, in particular to a sealing performance detection system for an emergency shut-off valve. Background technique [0002] The emergency shut-off valve is also called the safety shut-off valve, which means that in the event of an emergency, the valve will be quickly closed or opened to avoid accidents. [0003] The air tightness of the emergency shut-off valve is one of its main indicators. During the production process, the manufacturer needs to sample and test the air tightness of each batch of emergency shut-off valves, or test the air tightness of all of them. In the prior art, the emergency shut-off valve to be tested is installed on the testing pipeline, and after debugging, its airtightness is tested. However, in this way, each emergency shut-off valve to be tested needs to go through the process of installation, debugging, testing and disassembly, which is lengthy and ineff...
