Abstract

The invention provides a North-benz braking main valve with a decelerator and a filter net. The filter net is arranged in the braking main valve. The filter net is simple in structure and convenient to mount, and can be mounted outside a valve core of the braking valve for being directly arranged around the valve core, so that solid particles carried in gas can be prevented from entering the valve core, and accordingly, the working reliability of the valve core is promoted by a large margin, and the accidents related to braking are prevented from occurring.

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 deceleration and filter net for North Benz. 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 a...
