Abstract
A bidirectional quick release valve belongs to a component in an automobile air brake system. The quick release valve mainly overcomes the defects that the structure is complex, the size is large, the use cost is increased and hidden air leakage points are increased due to the fact that a transition pipe joint is needed to assemble a two-way valve and the quick release valve together at present. The utility model discloses a be equipped with respectively in the characterized in that valve body with the cavity of exhaust passage, output channel and vertical passageway's one end intercommunication and with the horizontal passageway of vertical passageway's the other end intercommunication, wherein, exhaust passage, output channel's the other end and the both ends of horizontal passageway are gas vent, delivery outlet and air inlet respectively, are equipped with the rubber diaphragm that is used for controlling exhaust passage and vertical passageway switching in the cavity, are equipped with rubber piston in the horizontal passageway, and the both ends of horizontal passageway are equipped with the end cap. The utility model discloses not only have former single two-way valve and single whole functions of putting the valve soon, have simple structure, small moreover, realize convenient, advantage with low costs to can improve the sealing reliability.
Description
Technical field
The utility model belongs to the parts in the Automobile air brake system.
Background technology
In the Automobile air brake system, 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, volume big, increased use cost, and, increased the hidden danger point of gas leakage because joint is many, reduced sealing reliability.
Summary of the invention
The purpose of this utility model be at above-mentioned deficiency provide simple in structure, volume is little, realize two-way easily rapid release valve.
The utility model is achieved in that and it is characterized in that being provided with in the valve body 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, be 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.
The upper end of above-mentioned exhaust passage is higher than the bottom surface of cavity.
The utility model not only has the repertoire of former single two-way valve and single rapid release valve, and has advantage simple in structure, that volume is little, realization is convenient, cost is low, and can improve the sealing reliability height.

The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: be provided with in the valve body 1 respectively and exhaust passage 2, cavity 5 that one end of delivery channel 3 and vertical passageway 4 is communicated with and the interconnection 6 that is communicated with the other end of vertical passageway 4, wherein, exhaust passage 2, the two ends of the other end of delivery channel 3 and interconnection 6 are respectively exhausr port 7, delivery port 8 and A admission port 9A and B admission port 9B, be provided with the rubber diaphragm 10 that is used to control exhaust passage 2 and vertical passageway 4 switchings in the cavity 5, be provided with rubber piston 11 in the interconnection 6, the two ends of interconnection 6 are provided with plug 12, and the bottom surface that the upper end of exhaust passage 2 is higher than cavity 5 promptly becomes the utility model.
Working process of the present utility model is: during inflation, high pressure gas feed A admission port 9A and B admission port 9B, when A admission port 9A air pressure during greater than B admission port 9B air pressure, as shown in figures 1 and 3, rubber piston 11 moves right, and until contacting with right side plug 12, and B admission port 9B is sealed; Otherwise when B admission port 9B air pressure during greater than A admission port 9A, rubber piston 11 is moved to the left, and A admission port 9A is sealed.High pressure gas enter cavity 5 by interconnection 6, vertical passageway 4 successively, and with exhaust passage 2 sealings, export from delivery port 8 by delivery channel 3 by high pressure gas under the effect of high pressure gas for rubber diaphragm 10.During exhaust, A admission port 9A and B admission port 9B lead to atmosphere, and the high pressure gas of output reflux from delivery port 8, arrive cavity 5 by delivery channel 3, and with rubber diaphragm 10 jack-up sealing Vertical Channel 4, high pressure gas pass through exhaust passage 2 from exhausr port 7 exhaust to atmospheres.
Claims (2)
1, a kind of two-way rapid release valve, it is characterized in that being provided with in the valve body 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, be 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.
2, by the described two-way rapid release valve of claim 1, it is characterized in that the upper end of said exhaust passage is higher than the bottom surface of cavity.
