Abstract
The utility model relates to a control valve for car vacuum booster belongs to car vacuum booster accessory technical field, which comprises the following components: a valve body, be provided with " L " shape skeleton in the valve body, the valve body hole has been seted up on the valve body, the mating holes has been seted up on the skeleton. The effect of this technical scheme skeleton is supported the last plane of valve body, improves the sealed effect and the life of valve body, and valve body hole and mating holes correspond each other simultaneously, and the high -pressure gas on the vacuum booster during operation makes the control valve transfers to on the skeleton of control valve below to reduce the risk that the control valve during operation warp, improved vacuum booster's life and safety in utilization, have profitable technological effect and the practical value that is showing.
Description
Technical field
This utility model relates to a kind of control valve for automobile vacuum booster, belongs to automobile vacuum booster accessory technical field.
Background technology
Automobile vacuum booster is brake power assisting device widely used from light-duty vehicle to compact car, general employing rubber diaphragm is divided into front/back cavity and completely cuts off with ambient atmosphere, being then turned on air door makes back cavity pour into air, utilizes and produces power-assisted under the effect of ante-chamber and back cavity draught head.Wherein control valve plays segmentation power-assisted air chamber in booster, controls air chamber connection and closes and control booster back cavity and the UNICOM of air and the effect of closedown.If control valve poor sealing, then booster will lose efficacy, operation inconvenience, and the foot power that touches on the brake is very big, and during use, potential safety hazard is relatively big, causes car braking fault, threatens personal safety.
Summary of the invention
For solving problems of the prior art, this utility model provides a kind of control valve for automobile vacuum booster, and concrete technical scheme is as follows:
A kind of control valve for automobile vacuum booster, including valve body, is provided with " L " shape skeleton, described valve body offers valve body hole, described skeleton offers mating holes in described valve body.
As the improvement of technique scheme, described valve body uses ethylene propylene diene rubber to make, and described skeleton uses hard material to make.
As the improvement of technique scheme, described valve body lower end is provided with the first sealing lip and the second sealing lip.
As the improvement of technique scheme, described first sealing lip is provided with Z-shaped front end, there is bottom described second sealing lip the guiding R face of evagination.
The effect of technique scheme skeleton is that the upper plane to valve body is supported, improve sealing effectiveness and the service life of valve body, valve body hole and mating holes are the most corresponding simultaneously, make the gases at high pressure in control valve transfer on the skeleton below control valve when vacuum booster works, thus the risk of deformation when reducing control valve work, improve service life and the safety in utilization of vacuum booster, there is useful technique effect and significant practical value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of control valve for automobile vacuum booster of this utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of control valve for automobile vacuum booster, including valve body 10, in described valve body 10, it is provided with " L " shape skeleton 20, described valve body 10 offers valve body hole 13, described skeleton 20 offers mating holes 21.In this technical scheme, the effect of skeleton 20 is that the upper plane to valve body 10 is supported, improve sealing effectiveness and the service life of valve body 10, valve body hole 13 and mating holes 21 are the most corresponding simultaneously, make the gases at high pressure in control valve transfer on the skeleton 20 below control valve when vacuum booster works, thus the risk of deformation when reducing control valve work, improve service life and the safety in utilization of vacuum booster.
Further, described valve body 10 uses the quality of rubber materials of good airproof performance in prior art to make, and preferably high-low temperature resistant (-40 DEG C～150 DEG C) and the ethylene propylene diene rubber of resistance to braking fluid is made, and described skeleton 20 uses the hard materials such as such as corrosion resistant alloy to make.
In the above-described embodiments, described valve body 10 lower end is provided with the first sealing lip 11 and the second sealing lip 12, it is provided with Z-shaped front end 111 on described first sealing lip 11, the effect of this front end 111 is the structural strength improving sealing lip, there is bottom described second sealing lip 12 the guiding R face 121 of evagination, this guiding R face 121 is able to ensure that the second sealing lip 12 is in good lubricating status, improving the sealing effectiveness of this side, the second sealing lip 12 that wherein a side of " L " shape skeleton 20 can be pointed to outside valve body 10 is fixed support.
Produce this this control valve and can use transmission injection pressure production technology, use profiled member and frame feeding apparatus feeding, Special ejector is used to touch, shorten feeding and the non-cutting time of the demoulding, ensure the relative stability of curing temperature, so that it is guaranteed that Novel control valve size and the stability of performance, improve and produce qualification rate and efficiency；Consider torn edges groove and the maintenance of clout groove, in considering, guiding R face 121 in outside requires smooth simultaneously, on Design of Dies, machinability and intensity to mold materials are had higher requirement, and by physical and mechanical properties and the contrast of machinability, are preferably Japan's SM1 steel；Board selection 718 steel are as Mold Making material.
Above embodiment of the present utility model is described in detail, but described content is only preferred embodiment of the present utility model, it is not to be regarded as limiting practical range of the present utility model, all impartial changes made according to this utility model scope and improvement etc., within all should still belonging to this utility model covering scope.
