Abstract

The invention provides valve testing equipment which comprises a valve testing device, the valve testing device comprises a positive pressure testing assembly, a negative pressure testing assembly, a testing pipeline, a first flow meter and a first pressure sensor, and the testing pipeline is provided with a first end and a second end which are opposite to each other; the first end of the testing pipeline is communicated with the second end of the first positive pressure pipeline and the second end of the first negative pressure pipeline, and the second end of the testing pipeline is used for being communicated with the testing end of a valve to be tested. According to the valve testing device, the comprehensive testing device is provided, the positive pressure testing assembly, the negative pressure testing assembly and the testing pipeline can be used for testing various working conditions of the valve to be tested, the performance of the valve can be conveniently and rapidly obtained, and the testing circuit is simple in structure, high in integration degree and high in testing efficiency.

Description

technical field [0001] The invention relates to the technical field of valve testing, in particular to a valve testing device. Background technique [0002] With the rapid development of the automobile industry, there are more and more types and applications of parts and components on automobiles. Various types of valve equipment are the key components for the vehicle to realize various control functions under different working conditions, and the development and testing of valve equipment becomes more and more important. Among them, the fuel tank isolation valve, as a key component of new energy hybrid vehicles, plays a key role in controlling fuel evaporative emissions of new energy hybrid vehicles. Therefore, the development verification and performance testing of the fuel tank isolation valve is very important. However, if you want to know the performance status of the tank isolation valve, you need to carry out a variety of performance tests to check the performance o...
