Problems solved by technology

The exhaust valve includes a middle valve body, an intake side plate and an exhaust side plate, and an intake diaphragm and an exhaust diaphragm are respectively installed between the middle valve body, the intake side plate and the exhaust side plate; the middle valve body The bottom is provided with pre-controlled pressure inlet P, air inlet D, air outlet C and exhaust air port O passage structure in turn, the exhaust side plate is provided with exhaust port T, and double air intake and exhaust side plates are installed between the air intake side plate and the exhaust side plate. The redundant structure of connected coils is composed of four coils, which are divided into two groups to control whether the moving iron core is excited or not, and the two groups of coils are mutually redundant backups, which can control the work of the anti-skid exhaust valve and improve the reliability of the system; The air exhaust port O, air inlet D and air outlet C adopt large-diameter ports and are arranged horizontally at the bottom of the middle valve body, which can quickly fill and exhaust the brake cylinder. At the same time, the flat structure is adopted, which can be easily disassembled and replaced, and is convenient for maintenance. However, the structure of this patent is relatively complicated, and the braking effect is relatively poor under the premise of not slipping

Abstract

The invention discloses an anti-skid exhaust valve which comprises an electromagnetic valve and a valve body. The electromagnetic valve is arranged between two end cover plates. Lining rings are arranged on the inner sides of the cover plates. Films are arranged between the cover plates and the lining rings. The films are opened in cooperation with the valve body, and therefore an air feeding function is achieved. The anti-skid exhaust valve has the advantages that the structure is compact, and installation and maintenance are convenient; in order to ensure the largest brake effect, boosting of a brake cylinder is achieved through pulse of the anti-skid exhaust valve, and the largest brake effect is achieved on the premise of being free of slip; when wheels are about to slide, lifting of the brake cylinder is achieved through pulse of the anti-skid exhaust valve, and therefore the wheels are prevented from sliding; assembly and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular, the invention relates to an anti-slip exhaust valve. Background technique [0002] When the rail vehicle is braking, the braking force generated by the brake shoe or the brake disc is to decelerate the train through the force between the wheel and the rail. However, if the braking force is too large or the wheel-rail adhesion coefficient is reduced, the wheels will lock and slide. Sliding will not only reduce the braking resistance of the train and increase the braking distance, but also scratch the wheels, affecting the safe and stable operation of the train. After the speed of the train is increased, especially after the speed of the passenger train is increased, in order to shorten the braking distance as much as possible, the adhesive force must be fully utilized, and the probability of the wheels sliding longitudinally also increases accordingly. [0003] The patent numbe...
