Abstract
The invention relates to an upper shell of quick release valve for braking, as well as the quick release valve. The upper shell comprises an upper shell body, wherein a gas inlet cavity is formed above the upper shell body and is communicated with an inner cavity of the upper shell; the gas inlet cavity comprises a cylindrical cavity and a conical cavity positioned below the cylindrical cavity; one end, with smaller diameter, of the conical cavity is connected with the lower end of the cylindrical cavity; one end, with bigger diameter, of the conical cavity is communicated with the inner cavity of the upper shell body. According to the technical scheme, the conical cavity is formed in the gas inlet cavity of the upper shell, so the condition that a membrane generates high-frequency vibration when being subjected to high-pressure gas impact can be inhibited, gas inlet squeal can be reduced and gas inlet speed can be increased.
Description
Technical field
The invention belongs to air-pressure brake technical field, particularly relate to a kind of braking quick release valve upper shell and quick release valve.
Background technology
Quick release valve is applied in truck air-pressure brake vehicle, and it is typically located at brake piping at brake chamber, rises
To the effect of Quick air-discharge when releasing braking, thus Rapid reversal braking.
Prior art quick release valve structure as shown in Figures 1 to 4, during assembling, venting valve 5 is sticked on lower house 2, sealing
Circle 3 is placed in the seal groove having in advance of upper shell 1, and diaphragm 4 uses four to bolt and bullet after being positioned on venting valve 5
Spring packing ring 6 is urgent through bolt 7, and above-mentioned assembling is required to two parts center alignment.
During automobile brake, the compressed air from brake valve enters quick release valve from air inlet A, promotes diaphragm 4 downwards tightly
Push down venting valve 5, blow the surrounding of diaphragm 4 open so that curved under diaphragm edge 41, as shown in Fig. 2 compressed air is along lower casing simultaneously
The radial groove of body 2, leads to, through 2 gas outlet B, the left and right air chamber being attached thereto, and needs quickly to make compressed air enter during braking
Air inlet chamber, so quick release valve need to have more preferable inflation rate, the flow area giving diaphragm at air inlet is bigger, charging efficiency meeting
Higher.
When automobile releases braking, the air vent through brake valve for the compressed gas in pipeline being connected with quick release valve is discharged, with
The compressed gas backflow of the left and right air chamber that quick release valve is connected promotes diaphragm 4 up, blocks air inlet A, the compressed gas in air chamber
Enter rapidly air through air vent C.
As described above, when quick release valve is braked, the gas from brake valve bends through journey under the edge promoting diaphragm
In, high pressure gas cognition causes diaphragm to produce altofrequency vibration, thus the air inlet producing quick release valve is uttered long and high-pitched sounds.
Quick release valve will promote that diaphragm 4 is up releasing the indoor compressed gas of braking seasonal epidemic pathogens, and this process can lead to diaphragm
Produce altofrequency vibration, thus the aerofluxuss producing quick release valve are uttered long and high-pitched sounds.Above-mentioned uttering long and high-pitched sounds is the master of quick release valve air inlet and exhaust noise
Want composition.
In order to solve exhaust noise in braking for the quick release valve, set by installing a damping in quick release valve lower end in recent years
Standby 8, as shown in Figure 3.Such technology has certain use to reducing quick release valve exhaust noise, but it only can reduce releasing system
The pneumatic noise producing during vent when dynamic, what when can not reduce braking, diaphragm 4 dither produced utters long and high-pitched sounds.And pacify
After having filled shock-absorption device, also exist take up room many, the problems such as high cost.
At air inlet, diaphragm applied force area is less, and during braking, aeration speed is slower, and when quick release valve is braked, to make by oneself
During the gas of dynamic valve is curved under the edge promoting diaphragm, high pressure gas cognition causes diaphragm to produce altofrequency vibration, thus producing
The air inlet of raw quick release valve is uttered long and high-pitched sounds.
Content of the invention
It is an object of the invention to provide a kind of braking quick release valve upper shell and quick release valve, to solve prior art quick release valve
Utter long and high-pitched sounds problem.
The present invention is achieved by the following technical solutions：
Quick release valve upper shell is used in a kind of braking, including upper shell body, is provided with air inlet above described upper shell body
Chamber, described inlet chamber and described upper shell inner space；
Described inlet chamber includes circular cylindrical cavity and is located at the cone-shaped cavity below described circular cylindrical cavity；Described conical cavity
In body, the little one end of diameter is connected with the lower end of described circular cylindrical cavity, in described cone-shaped cavity the big one end of diameter with described on
Enclosure body inner space.
In described cone-shaped cavity, the little internal diameter of diameter is identical with the internal diameter of described circular cylindrical cavity.
The both sides of described upper shell body are provided with gas outlet.
A kind of quick release valve, including air bleeding valve, lower house, sealing ring and diaphragm, further comprises the upper of any of the above-described
Housing；
Described drain valve sticks on described lower house, and described sealing ring is arranged at the sealing having in advance of described upper shell
In groove, described diaphragm is positioned on described drain valve, in the axial direction of cone-shaped cavity of the center line of described diaphragm and described upper shell
Line overlaps, will be urgent with described lower house for described upper shell by bolt.
The maximum gauge with diameter greater than described cone-shaped cavity of described diaphragm.
The invention has the beneficial effects as follows：
The technical program is passed through to arrange cone-shaped cavity on the air inlet cavity of upper shell, can suppress diaphragm by high pressure
Produce the situation of altofrequency vibration during gas impact, mitigate air inlet and utter long and high-pitched sounds it is also possible to increase intake velocity.
