Design on the performance test development bench of high pressure valve class products

A test system of valve class products based on industrial personal computer is developed. This test system is used for manufactories and quality supervisory departments to do the test of valve class products performance. Based on the control system of IPC and configuration software, the problem of collecting and storing performance parameters of valve class products with high speed was solved. This system uses data acquisition card and programmable logic controller to test the performances of valve class products, and the curves of the performances are described. With the alteration for high pressure manual regulator valve which be used in system, auto-regulation of valve opening was carried out. This data acquisition system has been used in a project of performance parameter testing of military valve class products, the date picking rate can reach 20 times/s and the measuring precision can reach 0.4%.
