Abstract
The utility model relates to a bi-pass quick release valve. The bi-pass quick release valve comprises an upper valve body and a lower valve body, wherein a gasket ring is arranged between the upper valve body and the lower valve body; two air inlets and an accommodating cavity are formed on the upper valve body; the accommodating cavity is communicated with the two air inlets, and is provided with a guide pipe; a slide valve is arranged in the guide pipe; a concave cavity, an exhaust port and two air outlets are formed on the lower valve body; the concave cavity is communicated with the two air outlets and extends to the upper end face of the lower valve body; a hollow channel connecting the accommodating cavity and the concave cavity is arranged at the bottom of the upper valve body; a membrane is arranged in the concave cavity; and a support table for supporting the membrane is arranged in the concave cavity, and is provided with a connecting channel which is connected with the exhaust port and the concave cavity. By adopting the technical scheme, the utility model provides the bi-pass quick release valve ensuring the whole braking system to be more reliable.
Description
Technical field
The utility model relates to a kind of bi-pass quick-releasing valve that is used for automobile brake.
Background technology
Valve element in the brake system of car is the key components and parts in the whole brake system, valve element mainly contains two-way cock and rapid release valve, two-way cock comprises two admission ports and an air extractor duct, and admission port can be controlled downstream components at the same time or separately to the air extractor duct air feed; Rapid release valve includes an admission port, two air extractor ducts, and admission port is controlled downstream components to the air extractor duct air feed.Present two-way cock and rapid release valve all are self contained systems, carry out function separately separately, therefore, in case breaking down, the air extractor duct of two-way cock will influence control to downstream components, equally, also can influence control in case the admission port of rapid release valve breaks down, thereby make that whole brake system is unreliable downstream components.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model is provided with two admission ports and two air extractor ducts, thereby a kind of whole brake system failure-free bi-pass quick-releasing valve more that makes is provided by with two-way cock and rapid release valve combination.
The technical solution of the utility model: a kind of bi-pass quick-releasing valve, include upper valve body, following valve body, on described, be provided with seal ring between the following valve body, described upper valve body is provided with two admission ports and a cavity volume, described cavity volume all is communicated with described two admission ports, be provided with a conduit in the described cavity volume, be provided with a guiding valve in the described conduit, described valve body down is provided with cavity, exhausr port and two air extractor ducts, described cavity is communicated with described two air extractor ducts and extends to described down valve body upper surface, described upper valve body bottom is provided with the hollow channel of a described cavity volume of connection and cavity, be provided with a diaphragm in the described cavity, also be provided with the brace table that is used to support described diaphragm in the described cavity, described brace table is provided with the interface channel that connects exhausr port and cavity.Adopt technique scheme, two admission ports and two air extractor ducts are set, as long as one of them admission port and air extractor duct is working properly just can guarantee that brake system is reliable.
Further improvement of the utility model: the corresponding described cavity volume bottom position in described upper valve body lower surface is provided with a cylindrical connecting bore, be provided with cylindrical column in the described connecting bore, be provided with reinforced rib between described connecting bore inwall and the described column, be provided with through hole in the described column, constitute the hollow channel of described connection cavity volume and cavity by described connecting bore, through hole.Adopt above-mentioned further improvement, it is smooth more to make that pressure gas flows into following valve body from upper valve body.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1, a kind of bi-pass quick-releasing valve, include upper valve body 1, following valve body 2, on described, be provided with seal ring 3 between the following valve body, described upper valve body 1 is provided with two admission ports 11 and a cavity volume 12, described cavity volume 12 all is communicated with described two admission ports 11, be provided with a conduit 4 in the described cavity volume 12, be provided with a guiding valve 5 in the described conduit 4, described valve body 2 down is provided with cavity 21, exhausr port 22 and two air extractor ducts 23, described cavity 21 is communicated with described two air extractor ducts 23 and extends to described down valve body 2 upper surfaces, described upper valve body 1 bottom is provided with the hollow channel 6 of a described cavity volume 12 of connection and cavity 21, be provided with a diaphragm 7 in the described cavity 21, also be provided with the brace table 8 that is used to support described diaphragm 7 in the described cavity 21, described brace table 8 is provided with the interface channel 81 that connects exhausr port 22 and cavity 21.In this specific embodiment, described two admission ports 11 are symmetricly set on the both sides of described upper valve body 1 respectively, and described conduit 4 is horizontally disposed with, and the endoporus 41 of described conduit 4 is admission port 11 positions of corresponding both sides respectively.
Corresponding described cavity volume 12 bottom positions in described upper valve body 1 lower surface are provided with a cylindrical connecting bore 61, be provided with cylindrical column 62 in the described connecting bore 61, be provided with the reinforced rib (not shown) between described connecting bore 61 inwalls and the described column 62, be provided with through hole 621 in the described column 62, constitute the hollow channel 6 of described connection cavity volume 12 and cavity 21 by described connecting bore 61, through hole 621.The routine techniques that is set to owing to reinforced rib is commonly used in rapid release valve, therefore, in this specific embodiment, no longer elaborates.
Principle of work of the present utility model: at the chaufeur glancing impact, speed-slackening signal can be sent in a loop of dual-chamber brake, pressure gas enters upper valve body 1 cavity volume 12 by the admission port of upper valve body 1 one sides, guiding valve 5 is pressed to the admission port of opposite side, pressure gas flows into the cavity 21 of valve body 2 down through hollow channel 6, diaphragm 7 is pressed to brace table 8, and pressure gas enters the compressed air brake cylinder apply brake by the air extractor duct 23 of following valve body 2 both sides.
