Description
Technical field
The invention belongs to field of automobile brake, specifically refers to the quick release valve interposed membrane in a kind of vehicle for aerobraking
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, is risen
The effect of Quick air-discharge when braking is released, so as to Rapid reversal braking.
Existing quick release valve structure is as shown in figure 1, when assembling, deflation valve 5 is sticked on lower house 2, sealing ring 3 is placed in upper casing
In the seal groove being provided with advance of body 1, diaphragm 4 is passed through after being positioned on deflation valve 5 using four pairs of bolts and spring washer 6
Bolt hole 7 is urgent, and above-mentioned assembling is required to two parts center alignments.
During automobile brake, the compressed air from brake valve enters quick release valve from air inlet A, promotes diaphragm 4 downwards tightly
Deflation valve 5 is pushed down, while blowing the surrounding of diaphragm 4 open so that curved under diaphragm edge 41, as shown in Fig. 2 compressed air is along lower casing
The radial groove of body 2,2 gas outlet B of Jing lead to the left and right air chamber being attached thereto.
When automobile releases braking, the air vent of the compressed gas Jing brake valve in the pipeline being connected with quick release valve is discharged, with
The compressed gas backflow of the connected left and right air chamber of quick release valve promotes diaphragm 4 up, blocks air inlet A, the compressed gas in air chamber
Jing air vents C enters rapidly air.
As described above, when quick release valve is braked, the gas from brake valve bends through journey under the edge for promoting diaphragm
In, gases at high pressure can cause diaphragm to produce altofrequency vibration, so as to the air inlet for producing quick release valve is uttered long and high-pitched sounds.
Compressed gas of the quick release valve in releasing braking seasonal epidemic pathogens room are up by promotion diaphragm 4, and this process can cause diaphragm
Altofrequency vibration is produced, so as to the aerofluxuss for producing quick release valve are uttered long and high-pitched sounds.
Above-mentioned uttering long and high-pitched sounds is the main component of quick release valve air inlet and exhaust noise.
In order to solve exhaust noise of the quick release valve in braking, 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 produced during vent when dynamic, what the dither of diaphragm 4 was produced when can not reduce braking utters long and high-pitched sounds.And pacify
After having filled shock-absorption device 8, also exist take up room it is many, the problems such as high cost.
