Description
technical field:
The utility model relates to automobile brake technical field, particularly relates to a kind of rapid release valve.
background technology:
Along with the quickening of socioeconomic development and people's rhythm of life, automobile obtains applying more and more widely in daily life and work.In brake system of car, often adopt rapid release valve to shorten the time of brake off at present.The principle of work of rapid release valve is: the pressurized air come from brake activation valve during braking enters from admission port, pushes away under diaphragm, and make diaphragm depart from admission port, and sealed by exhausr port, pressurized air enters compressed air brake cylinder by air extractor duct; During brake release, pressurized air pushes away on diaphragm, and make diaphragm depart from exhausr port, and sealed by admission port, the pressurized air in compressed air brake cylinder is discharged from exhausr port through air extractor duct, because freeing pipe is short out, just greatly reduces evacuation time, shortens the time of brake off.
Existing rapid release valve inside between admission port and exhausr port does not have quarantine measures, and foreign matter easily stretches into rapid release valve inside and causes damage to diaphragm.And there is complex structure, internal gas flow resistance is large and sealing reliability is poor shortcoming in existing rapid release valve.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides the rapid release valve that a kind of structure is simple, spacer is not easy damage, sealing reliability is high.
In order to achieve the above object, the technical solution of the utility model is:
A kind of rapid release valve, comprise valve body and valve gap bolted with described valve body, described valve body offers admission port, the both sides of described valve body offer respectively first air extractor duct perpendicular with admission port and the second air extractor duct, described valve gap offers exhausr port, and described admission port, the first air extractor duct and the second air extractor duct inside all offer negative thread; Described admission port is connected with the isolated tube being opened in valve inner, and described isolated tube inside is provided with the first isolation mount; Described isolated tube is connected with the first diversion division being opened in valve inner, and described first diversion division is connected with the containing cavity being opened in valve inner; The dividing wall of annular is installed in described containing cavity inside, forms exocoel and inner chamber between described dividing wall and containing cavity; Be provided with spring in described inner chamber, one end of described spring is connected with the inwall of containing cavity, and the other end of described spring is installed with spacer, and the one side that described spacer is connected with spring is provided with feet; Described exocoel is all connected with described first air extractor duct, the second air extractor duct; Described exhausr port is connected with the breather pipe being opened in valve gap inside, and described breather pipe is connected with the second diversion division being opened in valve gap inside, described second diversion division and described intracavity inter-connection.
Between described valve body and valve gap, stair-stepping seal ring is installed.
Second isolation mount is installed in described exhausr port.
Described valve body is provided with the first integrally manufactured mount pad, described valve gap is provided with the second integrally manufactured mount pad, described first mount pad and the second mount pad all offer fixed orifice.
The beneficial effects of the utility model are: a kind of rapid release valve of the present utility model, is all provided with isolation mount in admission port and exhausr port, can prevent foreign matter from stretching into and cause damage to spacer; Between valve body and valve gap, seal ring is installed, adds the sealing reliability of rapid release valve; Valve body and valve gap inside offer diversion division, decrease resistance during internal gas flow.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
