Description
Technical field
This utility model is related to technical field of automobile parts and in particular to a kind of quick release valve assembly.
Background technology
Fig. 2 show a kind of structure of parking quick release valve assembly, and this quick release valve assembly includes upper valve body 1 and lower valve body 2,
The both sides of lower valve body are provided with gas outlet 6, and the bottom of lower valve body is provided with air vent 7.Wherein between upper valve body and lower valve body, sealing connects
Connect, and between upper valve body and lower valve body, form a cavity 9, this cavity is communicated with gas outlet and air vent respectively.Its lumen
It is provided with air bleeding valve 10 between body and air vent, in cavity, be additionally provided with the diaphragm 4 shown in Fig. 1.When normal vehicle operation, compression is empty
Gas enters into cavity from air inlet 8, and gas pressure, on diaphragm 4, closes the valve port of air bleeding valve, and compressed air is defeated through gas outlet 6
Go out.When implementing parking braking, the air pressure cut-out of air inlet 8, diaphragm 4 is lifted up under inside cavity gas pressure, opens
The valve port of air bleeding valve, compressed air is from air vent 7 row to air.
Relevant national standard（GB7258）Regulation, commercial car, the car load air pressure of passenger vehicle are risen to by original 800kPa
1000kPa.Because parking quick release valve is in packing state all the time, the diaphragm easily deformation shown in pressurized generation Fig. 2, with car load
The lifting of air pressure, diaphragm deforms more seriously under long-time high pressure, makes diaphragm deformation position produce cracking, thus shorten putting soon
The service life of valve.
Content of the invention
The technical problems to be solved in the utility model is to provide that a kind of structure is improved is applied to parking quick release valve assembly
Diaphragm, to solve the technological deficiency of diaphragm changeableness in prior art.
In order to solve above-mentioned technical problem, the technical scheme that this utility model provides is as follows：A kind of quick release valve assembly, including
Upper valve body and lower valve body, are tightly connected between described upper valve body and lower valve body, and described upper valve body is provided with air inlet, lower valve body
Both sides are provided with gas outlet, and the bottom of lower valve body is provided with air vent, form a cavity between described upper valve body and lower valve body, described
Cavity is communicated with gas outlet and air vent respectively, is additionally provided with air bleeding valve between described cavity and air vent, is provided with described cavity
Diaphragm；Described diaphragm include diaphragm body and on diaphragm body near air bleeding valve side local location boss, described
The frontal projected area of boss is more than the valve port of air bleeding valve.
The quick release valve assembly of said structure, arranges boss by the local location in diaphragm body, changes the office of diaphragm
Portion's thickness, while not affecting air inlet and aerofluxuss response time and ensure vehicle braking and release the promptness braked, increases
The intensity of diaphragm, reduces the deflection of diaphragm, prevents the generation being cracked, improves the service life of quick release valve.
Further, the position of described upper valve body and lower valve body joint is provided with sealing member.
Further, the position of described upper valve body and lower valve body joint is provided with seal groove, and the sealing member in seal groove is close
Seal.
Further, it is bolted to connection between described upper valve body and lower valve body.
Brief description
Fig. 1 is the structural representation of diaphragm in this prior art；
Fig. 2 is the quick release valve assembly structure schematic diagram comprising diaphragm shown in Fig. 1；
Fig. 3 is the structural representation of the present embodiment diaphragm；
Fig. 4 is the present embodiment quick release valve assembly structure schematic diagram.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As shown in figure 4, a kind of quick release valve assembly of the present embodiment, including upper valve body 1 and lower valve body 2, wherein upper valve body 1 with
Lower valve body 2 is fixedly connected by bolt 3, and is provided with sealing member 5 between valve body 1 and lower valve body 2, preferably, upper valve body 1 with
The position that lower valve body 2 engages is provided with seal groove, and the sealing member in seal groove is preferably sealing ring.
In the present embodiment, upper valve body 1 is provided with air inlet 8, and the both sides of lower valve body 2 are provided with gas outlet 6, lower valve body 2
Bottom is provided with air vent 7, between upper valve body and lower valve body formed a cavity 9, this cavity 9 respectively with gas outlet 6 and air vent 7
Communicate.Wherein it is additionally provided with air bleeding valve 10 between cavity and air vent, in cavity 9, be provided with diaphragm 4.As maximum the changing of the present embodiment
Enter, as shown in figure 3, diaphragm 4 include diaphragm body 41 and on diaphragm body 41 local location near air bleeding valve side
Boss 42, the frontal projected area of this boss is more than the valve port of air bleeding valve, prevents diaphragm from moving left and right the sealing surface departing from valve port, no
Method plays sealing function.
It should be noted that only passing through in the present embodiment to increase the local thickness of boss increase diaphragm in local, rather than
To diaphragm Integral upset.The purpose being so designed that is, if diaphragm Integral upset, first, the limited space of cavity edge,
Thickness as diaphragm edge increases, then mobile space in cavity for the diaphragm is limited, and then can affect in exhaust process, diaphragm
By the height of jack-up, the promptness of the response time of aerofluxuss and braking and releasing braking can be had a negative impact；Second, film
Piece Integral upset, weight lifting is more, and in exhaust process, required pressure is also bigger, equally also can be to the response time of aerofluxuss
And the promptness of braking and releasing braking has a negative impact.
In sum, in the present embodiment by the way of local thickeies diaphragm, both increased the local thickness of diaphragm, in height
Reduce the deflection of diaphragm under air pressure, prevent cracking from producing, make the life-span of quick release valve assembly obtain larger lifting；With
When, diaphragm local thickeies and the space size of cavity edge is no affected, and weight is lifted less it is sufficient to ensure air inlet and row simultaneously
The response time of gas and braking and the promptness releasing braking.
In a word, the foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all
Any modification, equivalent and improvement made within spirit of the present utility model and principle etc., should be included in this practicality
Within new protection domain.
