Description
Technical field
The invention belongs to braking system technical field, a kind of braking quick release valve shell and quick release valve are particularly related to.
Background technique
Quick release valve is applied in truck air-pressure brake vehicle, is typically located at brake piping at brake chamber, rises
To the effect of Quick air-discharge when releasing braking, so that Rapid reversal is braked.
Prior art quick release valve structure is as shown in Figure 1 to Figure 3, and when assembly, deflation valve 5 is sticked in lower case 2, seals
Circle 3 is placed in the seal groove of upper housing 1 being provided in advance, and diaphragm 4 uses four pairs of bolts and bullet after being placed on deflation valve 5
Spring washer 6 is urgent across bolt 7, and above-mentioned assembly is required to two components centers alignment.
When automobile brake, the compressed air from brake valve enters quick release valve from air inlet A, pushes diaphragm 4 downward tightly
Deflation valve 5 is pushed down, while blowing the surrounding of diaphragm 4 open, so that it is curved under diaphragm edge 41, as shown in Fig. 2, compressed air is along lower casing
The radial groove of body 2 leads to the left and right gas chamber being attached thereto through 2 gas outlet B, when braking need quickly to make compressed air into
Air inlet chamber, so quick release valve need to have better inflation rate, the flow area that diaphragm is given at air inlet is bigger, volumetric efficiency meeting
It is higher.
When automobile releases braking, the compressed gas in pipeline being connected with quick release valve is discharged through the exhaust outlet of brake valve, with
The compressed gas reflux of the connected left and right gas chamber of quick release valve pushes 4 uplink of diaphragm, blocks air inlet A, the indoor compressed gas of gas
It is discharged into atmosphere rapidly through exhaust outlet C.
As described above, when quick release valve is braked, the gas from brake valve bends through journey under the edge for pushing diaphragm
In, high pressure gas can cause diaphragm to generate high-frequency vibration, so that the air inlet for generating quick release valve is uttered long and high-pitched sounds.
Quick release valve indoor compressed gas of gas when releasing braking will push 4 uplink of diaphragm, this process will lead to diaphragm
High-frequency vibration is generated, so that the exhaust for generating quick release valve is 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 ingredient.
In order to solve exhaust noise of the quick release valve in braking, set in recent years by installing a damping in quick release valve lower end
Standby 8, as shown in Figure 3.Such technology has certain use to quick release valve exhaust noise is reduced, but it only can reduce releasing system
The pneumatic noise generated when vent when dynamic, what 4 high-frequency vibration of diaphragm generated when can not reduce braking utters long and high-pitched sounds.And pacify
The problems such as after having filled shock-absorption device, it is more that there is also occupied spaces, at high cost.
Summary of the invention
