Abstract

The utility model discloses a gaseous one -way hand brake valve that passes through, which comprises the following components: a valve body. The valve body on set up at least three gas passage, three gas passage does respectively: air inlet, gas outlet and gas vent, the air inlet is the check valve structure. The utility model discloses reduced the risk that parking braking was triggered when the vehicle travel greatly, the security that has improved the vehicle, the protection driver and crew the security of the lives and property, the practicality is strong.

Description

The hand brake valve that gas unidirectional passes through
Technical field
The utility model relates to vehicle hand valve, is specifically related to the hand brake valve that a kind of gas unidirectional passes through.
Background technology
At present, domestic goods carrying vehicle rapid industrial development, technology is reformed day by day.But the safety traffic technology with regard to automobile also needs to improve constantly, especially brake system.Braking during standstill is the vehicle of gas braking model, runs into pipeline gas leakage in the process of moving and automatically triggers braking during standstill, makes trailing wheel suddenly locking and the occurring risk of turning on one's side at high speeds.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides the hand brake valve that a kind of gas unidirectional passes through.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
The hand brake valve that gas unidirectional passes through, comprises valve body; Described valve body is arranged at least three gas passages; Described three gas passages are respectively: admission port, air extractor duct and exhausr port; Described admission port is one-way valve structures.
Further technical scheme is that the admission port of one-way valve structures comprises an inlet suction port, and described inlet suction port upper end is connected with described valve body; Described inlet suction port lower end is provided with gasket seal, is provided with elastomeric element between described gasket seal and valve body.
Further technical scheme is elastomeric element is spring.
Compared with prior art, the beneficial effects of the utility model are: the utility model substantially reduces the risk that when vehicle travels, braking during standstill is triggered, and improves the safety of vehicle, and the security of the lives and property of protection driver and crew is practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of admission port in the utility model embodiment.
Detailed description of the invention
All features disclosed in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification sheets (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in detail.
As depicted in figs. 1 and 2, according to an embodiment of the present utility model, the present embodiment discloses the hand brake valve that a kind of gas unidirectional passes through, and it comprises valve body 4; Valve body is arranged at least three gas passages; Described three gas passages are respectively: admission port 1, air extractor duct 2 and exhausr port 3; Admission port is one-way valve structures.Concrete, the admission port of one-way valve structures comprises an inlet suction port 8, and inlet suction port upper end is connected with valve body; Inlet suction port lower end is provided with gasket seal 7, is provided with elastomeric element between gasket seal and valve body.
When automobile in the process of moving, admission port and air extractor duct are identical, if run into admission port front end Leakage Gas occurs, atmospheric pressure declines, because admission port has non-return valve function, gas from air extractor duct to air inlets flow, thus can not ensure that the air pressure needed for braking during standstill does not reduce, and avoids high speed descend the unexpected locking of trailing wheel and the risk of rollover occurs.
Concrete, valve body 4 has admission port 1, air extractor duct 2 and exhausr port 3; Inlet suction port 8 one end is connected with valve body 4, has gasket seal 7 in inlet suction port 8, has spring 6 in gasket seal 7 and valve body 4.By above embodiment, when handle 5 is placed in the position of " A ", i.e. " OK ", when namely removing braking during standstill, pressurized air only can overcome spring 6 resistance from admission port 1 by gasket seal 7 and enter valve body, then enters spring air chamber from air extractor duct 2, removes braking during standstill.When handle 5 is placed in the position of " B ", namely " stay ", namely when parking brake pulled on by vehicle, the passage leading to admission port 1 in valve body 5 is closed, the passage simultaneously leading to exhausr port 3 is opened, and the pressurized air of spring air chamber flows to exhausr port 3 by air extractor duct 2, enters air, the spring air chamber air pressure controlling braking during standstill declines, and enters braking during standstill state.
When vehicle is in motoring condition, handle 5 is placed in " A " position, admission port 1 is communicated with air extractor duct 2, if now there is the pipeline before admission port 1 or parts gas leakage, then the air pressure at admission port 1 place declines, and cannot overcome the air pressure in the resistance of spring 6 and air extractor duct 2, gasket seal 7 can seal up admission port 1 firmly, prevent under the state do not pulled the hand brake, the spring air chamber air pressure of control B car braking declines.
Spoken of in this manual " embodiment ", " another embodiment ", " embodiment ", etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any one embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although the multiple explanatory embodiment here with reference to utility model is described the utility model, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the constituent elements of subject combination layout and/or layout.Except the modification of carrying out constituent elements and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
