Description
Technical field
The utility model relates to the elastic element of mechanical field, is specifically related to a kind of diaphragm of rapid release valve.
Background technology
Rapid release valve is generally arranged in compression air brake pipeline, has the effect of carrying out Quick air-discharge in the time of brake off, is conducive to quick brake off.As shown in Figure 1, rapid release valve comprises diaphragm 1 ', upper shell 2, lower house 3, seal ring 4, upper shell 2, lower house 3 are fixed and are connected with spring washer 6 by bolt, are provided with seal ring 4 between two housings, and diaphragm 1 ' is contained in upper shell 2, lower house 3 inner chambers.The flat diaphragm that diaphragm 1 ' is consistency of thickness, the lower camber side of upper shell 2 is diaphragm deformation areal of support, between diaphragm peripheral part and upper shell 2, lower house 3, has certain interval, can move up and down.Upper shell 2 is provided with induction opening 21, lower house 3 is provided with the deflation hole relative with induction opening 21 32 and two air gates that are oppositely arranged 33, the induction opening 21 of upper shell 2 is connected with brake activation valve, and the air gate 33 at lower house 2 two ends is connected with the left and right compressed air brake cylinder of trailing wheel, the logical atmosphere of deflation hole 32.
When automobile brake, pressurized air from brake activation valve enters rapid release valve from induction opening 21, promote diaphragm 1 ' and tightly push down venting valve 5 downwards, blow diaphragm 1 ' surrounding open simultaneously, make under diaphragm edge curved, pressurized air, along the radial groove of lower house 3, is led to the left and right compressed air brake cylinder being attached thereto through 2 air gates 33.
When automobile brake off, pressure gas in the pipeline being connected with rapid release valve is discharged through the deflation hole 32 of brake activation valve, it is up that the pressure gas backflow of the left and right air chamber being connected with rapid release valve promotes diaphragm 1 ', blocks induction opening 21, and the pressure gas in air chamber enters rapidly atmosphere through deflation hole 32.But it is up that rapid release valve pressure gas in air chamber in the time of brake off will promote diaphragm 1 ', can cause diaphragm 1 ' to produce high-frequency vibration, thereby the exhaust that produces rapid release valve utter long and high-pitched sounds, this is uttered long and high-pitched sounds is the overriding noise of rapid release valve exhaust.
As shown in Figure 2, in order to solve the exhaust roar of rapid release valve in braking, conventionally connect a shock-absorption device 7 at the deflation hole place of rapid release valve, this shock-absorption device 7 has certain effect to reducing rapid release valve exhaust roar, but the pneumatic noise producing when exhausr port exhaust when it only can reduce brake off, when braking diaphragm can not be reduced because of uttering long and high-pitched sounds that high-frequency vibration produces, thereby noise can not be effectively reduced.This shock-absorption device existence simultaneously takes up room many, high in cost of production problem.
Utility model content
In order to address the above problem, the utility model is by a kind of diaphragm of rapid release valve is provided, when this diaphragm can significantly reduce rapid release valve exhaust because of the whistler of diaphragm generation of vibration.
The technical scheme addressing the above problem:
A diaphragm for rapid release valve, it comprises flat diaphragm, boss, and described boss is positioned at a side of described flat diaphragm, and described flat diaphragm and described boss coaxially arrange, and described boss is positioned at the middle part of described flat diaphragm.
Selectable, described flat diaphragm and described boss are cylindric.
Selectable, the diameter of described flat diaphragm is a, and thickness is b, and the diameter of described boss is 0.5a～0.6a, and thickness is b～1.2b.
A kind of rapid release valve, described rapid release valve comprises diaphragm, upper shell, lower house, venting valve, described upper shell is provided with induction opening, described lower house is provided with the deflation hole relative with induction opening and two air gates that are oppositely arranged, described upper shell, described lower house are fixedly connected with, and described diaphragm is arranged in upper shell inner chamber and lower housing cavity, and described boss is towards upper shell, described venting valve is elasticity body, and described venting valve is fixed with described lower house and is communicated with described deflation hole; When induction opening air inlet, described flat diaphragm covers described deflation hole, and described boss and described induction opening have gap; When deflation hole exhaust, described boss is positioned at induction opening.
Selectable, described rapid release valve comprises seal ring, and described upper shell has seal groove, and described seal ring is positioned at described seal groove.
The beneficial effects of the utility model:
The mode that diaphragm of the present utility model adopts one side to increase by place's boss improves the rigidity of diaphragm, and boss is positioned at the main stressed middle part of diaphragm, can reduce the oscillation frequency of diaphragm, and then reduces the noise of rapid release valve.Meanwhile, the utility model is simple in structure, successful, and cost is low, does not take space outerpace.
