Abstract

The invention provides an air control valve with an accelerating and relieving function, which comprises a main valve body, a main air cylinder, an auxiliary air cylinder, an auxiliary air cylinder, an auxiliary air cylinder, an auxiliary air cylinder, an auxiliary air cylinder, an auxiliary air cylinder, an auxiliary air cylinder, an auxiliary air cylinder, an auxiliary air cylinder and an auxiliary air cylinder, and is characterized in that the main valve body is provided with a main valve upper cavity and a main valve lower cavity which are arranged at an interval; the release valve body is provided with a driving cavity and an air inflation cavity which are arranged at an interval, an air inlet of the air inflation cavity is communicated with the acceleration release air cylinder, and an air outlet of the air inflation cavity is communicated with a train pipe; the release valve element is movably arranged in the driving cavity, the release valve element divides the driving cavity into a train cavity and an auxiliary air cavity, the train cavity is communicated with the train pipe, the auxiliary air cavity is communicated with the main valve lower cavity, and the end of the release valve element is provided with a plugging piece extending into the inflation cavity; the plugging piece is provided with a communicating position for communicating the air outlet and the air inlet of the inflating cavity and a closing position for separating the air outlet and the air inlet of the inflating cavity. By means of the technical scheme, the problem that the train acceleration relieving effect is poor can be solved.

Description

technical field [0001] The present invention relates to the technical field of air control valves, in particular, to an air control valve with an acceleration and mitigation function. Background technique [0002] The air control valve, the auxiliary air cylinder, the acceleration relief air cylinder and the brake cylinder constitute the braking system of the railway freight car. Among them, the air control valve is the core control component of the vehicle braking system, which controls the vehicle braking system to generate braking and relief. At present, the number of railway freight trains is large and the length of the train is large, so the performance requirements of the air control valve are particularly high, which is mainly reflected in the requirement that the control valve transmits the braking or relief action quickly, and the braking or relief action of all relevant control valves in the train is highly synchronized. . [0003] In the related art, the air con...
