104 distribution valve air pressure monitoring module

Abstract

The invention discloses an air pressure monitoring module for a 104 distribution valve. The module comprises an air path plate installed between a main valve part and a middle body of the 104 distribution valve. A first main air hole, a second main air hole and a third main air hole formed in the main valve part are communicated with a first auxiliary air hole, a second auxiliary air hole and a third auxiliary air hole of the middle body through a first connecting hole, a second connecting hole and a third connecting hole formed in the air path plate respectively. A first detection channel communicated with the first connecting hole, a second detection channel communicated with the second connecting hole and a third detection channel communicated with the third connecting hole are arranged in the air path plate. The air pressure monitoring module for the 104 distribution valve is simple and compact in structure and can be additionally installed between the main valve part and the middle body of the 104 distribution valve directly to lead out an air path connecting a train pipe, a braking cylinder and an auxiliary air cylinder of a railway vehicle for air pressure detection; an original braking pipeline of the railway vehicle does not need to be refitted, so that the workload is small; the module can be additionally installed on the existing railway vehicle directly, so that compatibility is high; the number of connecting portions is small, so that sealing is convenient, and the hidden danger of leakage is small.

Description

technical field [0001] The invention relates to a monitoring device for a rail vehicle, in particular to a 104 distribution valve air pressure monitoring module. Background technique [0002] The 104-type air distribution valve is the main brake control valve currently used on 25G passenger cars, and it is used in a large amount. In order to improve its operational safety and meet the needs of the 5T system, its air pressure should be monitored in real time. Most of the existing technical solutions are to directly modify the pipeline of the braking system, directly install a pressure sensor on the pipeline of the braking system and transmit the pressure signal value to the corresponding monitoring equipment, although this kind of technology has good compatibility, It can be applied to various car models, but in the process of realization, there are many changes to the brake pipeline of the vehicle, the workload is large, there are many hidden leakage points, and the structur...

Problems solved by technology

[0003] The present invention designs a structure for the current air pressure monitoring system of the 104 air distribution valve, which requires a large modification of the brake pipeline, which has a large workload and is prone to hidden dangers of leakage, which is not conducive to the transformation and installation of the original rail vehicles. Compact, easy to install, easy to retrofit 104 distribution valve air pressure monitoring module
