Abstract

The invention discloses a main braking valve with a decelerating and filtering screen for Jianghuai vehicles. The decelerating and filtering screen is arranged in the main braking valve, for the decelerating and filtering screen, the structure is simple, the mounting is convenient, and the decelerating and filtering screen can be mounted outside a valve core of a braking valve and directly arranged around the valve core. Through the adoption of the main braking valve, the situation that solid shell bodies which are carried in gas enterthe valve core can be avoided, so that the operational reliability of the valve core is greatly improved, 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 master brake valve with retarder and filter. 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 co...
