Vacuum valve quality detection platform

Abstract

The invention belongs to the technical field of quality detection. The technical scheme is that: three ports of a vacuum valve 5 are respectively connected with an air inlet of a first flow sensor 4, an air outlet of a second flow sensor 6 and a switching control signal output end of a pulse power source 2 correspondingly; three ports of a vacuum cylinder 1 are respectively connected with an air outlet of the first flow sensor 4, the air inlet of a pressure sensor 9 and an extract opening of a vacuum pump control unit 10 correspondingly; three signal input ends of a data acquisition unit 7 are respectively connected with the signal output ends of the first flow sensor 4, the second flow sensor 6, the pressure sensor 9 correspondingly; a PC 3 is communicated with the pulse power source 2 and a first singlechip 8 through serial ports; and the P0 and P1 ports of the first singlechip 8 are respectively connected with a signal output end of the data acquisition unit 7 and a signal input end of the vacuum pump control unit 10 correspondingly. The invention has the advantages of good time-shared control function and real-time automatic detection performance, friendly human-computer interface and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of quality detection. In particular, it relates to a quality detection platform for vacuum valves. Background technique [0002] With the development of automatic control technology, the application of vacuum valve is more and more extensive. For example, in metallurgy, machinery, petrochemical, electric power and other industrial production and automotive industries, vacuum valves can be used to adjust various states of gas. In these fields, vacuum valves are closely related to major technical and economic indicators such as production safety, production efficiency, product quality, and energy conservation, and the performance requirements for the stability and reliability of vacuum valves are also getting higher and higher. Therefore, as a vacuum valve manufacturer, it is necessary to test the performance of the produced vacuum valve and comprehensively judge whether the quality of the vacuum valve is qu...

AI Technical Summary

Problems solved by technology

[0003] At present, the vacuum valve detection system used in China is a manual detection platform. This kind of manual detection platform is complex and inefficient to operate, and has high requirements for operators. operation, it is difficult to carry out real-time automatic detection, so it is easy to produce large errors, resulting in unsatisfactory detection accuracy

In addition, the labor intensity of the operator is very high, and the detection efficiency is low
