Gas control reversing valve detection device and detection method

Abstract

The invention discloses a gas control reversing valve detection device which is fixed on a rack. The device comprises a cylinder tooling which blocks a 2 port of an air compressor air inlet interface of a gas control reversing valve, a right cylinder tooling which blocks a 41 port of a pressure regulating valve air inlet interface of the gas control reversing valve, and a left cylinder tooling which blocks a 42 port of an exhaust brake valve control interface of the gas control reversing valve. Each cylinder is provided with a plug. The air inlet of each cylinder carries out air inlet, and a plug which is connected with the cylinder to stretch forward to block an interface of the gas control reversing valve. A positioning seat which fixes the gas control reversing valve is arranged on the rack. A spacing seat is arranged on one end of the positioning seat. A blocking tooling is arranged on one side of the positioning seat. A blocking plate which is corresponding to an 11 port of an air cleaner interface and a 12 port of a turbocharger interface of the gas control reversing valve is arranged on the blocking tooling. The invention further provides a pressure circuit and a detection method of the gas control reversing valve detection device. The detection device provided by the invention has the advantages of high test efficiency and test precision, simple and practical fixation component structure and high clamp precision.

Description

technical field [0001] The invention relates to the field of detection devices for pneumatic system products, in particular to a detection device and method for a pneumatic control reversing valve. Background technique [0002] Pneumatic control reversing valve is the control element in the pneumatic system, used to control the flow direction of the fluid in the system. The development of industrial automation, on the one hand, puts forward higher requirements for the accuracy and adjustment performance of the pneumatic control system, and on the other hand, has higher requirements for the control components in the pneumatic system. In countries with relatively developed industries, electro-pneumatic proportional servo technology, pneumatic position servo control system, and pneumatic servo control system have moved from the laboratory to industrial applications. As one of the most basic control components in the air control system, air control The performance test of the r...
