Abstract

The invention discloses a Jianghuai main brake valve provided with a filter screen. The filter screen is arranged inside the main brake valve. The filter screen is simple in structure, is convenient to install, and can be arranged outside a valve core of the brake valve. The filter screen is directly arranged around the valve core, and solid particles carried in gas can be prevented from entering the valve core, so that the working reliability of the valve core is enhanced greatly, and braking accidents are avoided.

Description

technical field [0001] The invention mainly relates to the technical field of parts of automobile brake valves, in particular to a JAC brake master valve with a filter screen. Background technique [0002] At present, there are generally filters in the pipeline of the braking system, which are used to filter the solid particle impurities flowing with the gas in the air pipe, so as to ensure that each braking component is not affected by the solid particle impurities and ensure the reliability of its work. However, due to the distance between the filter and the spool of each valve, it cannot be avoided that the filtered gas will be polluted by other newly generated solid particles before entering the spool. Sometimes solid particles will still enter the spool and affect the valve core. The sealing of the air leakage caused the accident, and a new solution needs to be proposed. [0003] The braking system of trucks and heavy-duty vehicles in the prior art brakes too quickly, ...
