Abstract

The invention discloses a brake main valve of a Jiefang 151 belt filter screen, wherein a filter screen is arranged in the brake main valve. The filter screen is simple in structure, convenient to mount, and capable of being mounted outside a valve element of the brake valve; the filter screen is directly arranged around the valve element, and solid shells carried in air can be prevented from entering the valve element, so that the working reliability of the valve element is greatly increased, and brake 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 brake master valve with a filter screen. Background technique [0002] At present, a filter is generally installed in the pipeline of the brake system to filter the solid particle impurities that flow with the gas in the air pipe, so as to ensure that each brake component is not affected by the solid particle impurities and ensure the reliability of its work. However, because the filter is far away from the valve core of each valve, it cannot be avoided that the filtered gas is again contaminated by other newly generated solid particles before entering the valve core. Sometimes solid particles will enter the valve core and affect the valve core. The sealing caused air leakage accidents, and new solutions need to be proposed. [0003] The brake systems of trucks and heavy vehicles in the prior art brake too fast, and the foot feel is not well controlled...
