Abstract
The utility model belongs to the technical field of mechanical equipment and relates to an automobile part, in particular to a quick release valve for quick air release when an automobile is braked. The quick release valve solves the technical problem that the existing quick release valve is inconvenient to use and operate and poor in sealing performance. The quick release valve comprises an upper valve body and a lower valve body, the upper valve body and the lower valve body are connected with each other to form an accommodating cavity, a control port is arranged at one end of the upper valve body, which is far away from the lower valve body, an air inlet is further arranged on the upper valve body, an exhaust port is arranged at one end of the lower valve body, which is far away from the upper valve body, two air outlets are further arranged on the side surface of the lower valve body, which is vertical to the exhaust port, and the air inlet, the air outlets and the exhaust port are all communicated with the accommodating cavity. The quick release valve is reasonable in design, simple in structure, low in equipment cost, convenient to use and operation and good in sealing performance and hardly cause air leakage.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of vehicular spare parts, especially relates to a kind of rapid release valve of quick exhaust when being used for braking automobile.
Background technology
Along with the quickening of The development in society and economy and people's rhythm of life, automobile obtains application more and more widely in daily life and work.In brake system of car, often need at present to adopt the transition conduit joint that two-way valve and rapid release valve are fitted together.Not only complex structure, bulky has increased use cost, and because joint is many, has increased the hidden danger point of gas leakage, has reduced sealing reliability.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have proposed multi-form solution.For example; The Chinese patent document discloses a kind of two-way rapid release valve [application number: 200820192159.8]; In valve body, be provided with cavity that is communicated with an end of exhaust passage, delivery channel and vertical passageway respectively and the interconnection that is communicated with the other end of vertical passageway; Wherein, the other end of exhaust passage, delivery channel and the two ends of interconnection are respectively exhausr port, delivery port and admission port, are provided with the rubber diaphragm that is used to control exhaust passage and vertical passageway switching in the cavity; Be provided with rubber piston in the interconnection, the two ends of interconnection are provided with plug.
Such scheme has improved prior art to a certain extent, makes that the structure of rapid release valve is comparatively simplified, volume is little, effectively reduces cost.But still there is technical matterss such as using operation inconvenience, leak tightness difference in this scheme.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, and equipment cost is low, use easy to operate, the rapid release valve of good seal performance.
For achieving the above object; The utility model has adopted following technical proposal: this rapid release valve; Comprise upper valve body and following valve body, described upper valve body is interconnected to form cavity volume with following valve body, and the end away from following valve body on upper valve body is provided with the control mouth; Also be provided with admission port on the described upper valve body; End away from upper valve body on the described valve body down is provided with exhausr port, and the side perpendicular to exhausr port on following valve body also is provided with two air extractor ducts, and described admission port, air extractor duct and exhausr port all are communicated with cavity volume.
In above-mentioned rapid release valve, the position of the corresponding exhausr port in described cavity volume bottom is provided with supporting diaphragm to be opened/closed, is being provided with the brace table that is used to carry said supporting diaphragm on the valve body down.
In above-mentioned rapid release valve, described supporting diaphragm is a circular configuration, and described brace table is a cylindrical structure.
As preferably, in above-mentioned rapid release valve, take demountable structure to be connected between described brace table and the following valve body.
Further, in above-mentioned rapid release valve, described admission port, air extractor duct and exhausr port all are connected with compressed air brake cylinder.
As preferably, in above-mentioned rapid release valve, described upper valve body is fixing integrative-structure with following valve body.
Compared with prior art, the advantage of this rapid release valve is: reasonable in design, simple in structure, equipment cost is low, uses easy to operately, and good seal performance is not easy to take place gas leakage.
Description of drawings
Fig. 1 is the cutaway view that the utility model provides.
Among the figure, upper valve body 1, following valve body 2, cavity volume 3, control mouth 4, admission port 5, exhausr port 6, supporting diaphragm 7, brace table 8.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
As shown in Figure 1, this rapid release valve comprises upper valve body 1 and following valve body 2; Upper valve body 1 is interconnected to form cavity volume 3 with following valve body 2; End away from following valve body 2 on upper valve body 1 is provided with control mouth 4, also is provided with admission port 5 on the upper valve body 1, and the end away from upper valve body 1 on the following valve body 2 is provided with exhausr port 6; Side perpendicular to exhausr port 6 on following valve body 2 also is provided with two air extractor ducts; Admission port 5, air extractor duct and exhausr port 6 all are communicated with cavity volume 3, and admission port 5, air extractor duct and exhausr port 6 all are connected with compressed air brake cylinder, and upper valve body 1 is fixing integrative-structure with following valve body 2.The position of the air extractor duct here and shape and structure can be selected according to actual needs, can be arranged on down valve body 2 the same sides, also can be located on the not ipsilateral of following valve body 2.
The position of the corresponding exhausr port 6 in cavity volume 3 bottoms is provided with supporting diaphragm 7 to be opened/closed, is being provided with the brace table 8 that is used to carry said supporting diaphragm 7 on the valve body 2 down.That supports diaphragm 7 is arranged so that bleeding is convenient, helps strengthening the sealing property of whole rapid release valve simultaneously.Supporting diaphragm 7 is a circular configuration in the present embodiment, and brace table 8 is a cylindrical structure, takes demountable structure to be connected between brace table 8 and the following valve body 2.The version that the supporting diaphragm 7 here and brace table 8 can be taked multiple various kinds according to the shape and structure and the exhaust needs of exhausr port 6, the connection mode between brace table 8 and the following valve body 2 also can be selected according to actual needs.
