Problems solved by technology

In the existing air brake valve, since there is only one micro switch controlled by the positioning cam, in the four working positions of the air brake valve, at most two electrical signals can only be generated and transmitted to the wireless synchronous control system, so In fact, the wireless synchronous control system controlling the slave locomotive can only receive the working signals of the two working positions of the master locomotive at most, but cannot receive the working signals of the other two working positions of the master locomotive. Synchronous action of master locomotive

Abstract

The invention provides an air brake valve for a locomotive, which is characterized by comprising a cam box, a valve body and an air exhaust valve; a hand shaft is arranged in the cam box, the center of the hand shaft is provided with a mandril, and the hand shaft is sequentially sleeved with a first cam, a second cam, a third cam and a fourth cam from up to down; a conversion plunger is arranged in the valve body, preset distance is pre-reserved between the conversion plunger and the first cam, and a positioning plunger and an action plunger are also arranged in the valve body; the air brake valve for the locomotive also comprises an interlock switch group; and the interlock switch group comprises a first micro switch controlled by the first cam, a second micro switch controlled by the second cam, a third micro switch controlled by the third cam, and a fourth micro switch controlled by the fourth cam. The invention can transmit the signals of the four working positions of the air brake valve to a computer, and the computer controls a driven locomotive to realize the synchronous action with a main control locomotive.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to an air brake valve for a locomotive. Background technique [0002] Electro-pneumatic braking is a commonly used braking form of locomotive braking systems. Taking the DK-1 locomotive electro-pneumatic brake developed in the 1970s in my country as an example, it has the advantages of accurate decompression and fast air charging. , Brake valve control handle is flexible, noise pollution is small, etc., and it is widely used in the braking system of locomotives at present. [0003] In the locomotive electro-pneumatic brake, the air brake valve is its core component. The air brake valve has two working conditions: electric vacant position and air position. In the electric vacant position, the braking, pressure maintenance and release of the locomotive are controlled independently by controlling the pressure of the action chamber. At this time, the air brake valve acts as a "small gate...
