Interior surface is developed, and the air of air inlet is isolated with inner cavity；Collector under the action of the first spring force with valve body left end
Inner surface develops, and the air of air hatch is isolated with body cavity, inner cavity is communicated with gas outlet and exhaust outlet at this time.
The piston be rubber parts, when valve body assembly air inlet inflation when, piston under the influence of air pressure, compressed spring edge
Valve body assembly inner wall move down, piston is contacted with valve body assembly lower end exhaust outlet, exhaust outlet is blocked, at this time gas
Body cavity can be reached by air inlet, then arrives gas outlet；When valve body assembly air inlet is died, effect of the piston in spring force
Lower jack-up is developed with valve body assembly interior surface, and the atmosphere of exhaust outlet is released quickly against into the gas of body cavity and gas outlet
In, to realize fast playing function.
The collector is bottom cone, end cylindrical；Effect of the collector bottom cone in spring force
It is lower to be bonded with the conical surface of valve body assembly, valve body assembly inner cavity is isolated with air hatch；When the pressure that need to test valve body assembly inner cavity
When, collector is jacked up to the right, the first spring is compressed, so that inner cavity is communicated with air hatch, to realize test function.
The dust cover is rubber sheath, is connected with valve body assembly, dust cover internal diameter and valve body assembly air hatch external screw thread
Match, when collector does not take gas, dust cover covers air hatch, prevents dust from entering valve body assembly inner cavity.
It is put fastly and test function the utility model has the advantages that 1. this braking valve arrangement are integrated, can effectively meet laws and regulations requirement.2, this makes
The dynamic fast playing function of valve is integrated with air inlet, can promotion braking system release time by a relatively large margin.3, structure of the invention
Simply, manufacturing process and assembly technology are simple, and function and performance are greatly improved, and production cost is low, high production efficiency.
