Description
Technical field
The utility model relates to the motor vehicle fittings field, particularly relates to the exhausted quick-fried valve of a kind of Motor Vehicle.
Background technique
Motor Vehicle becomes outstanding traffic problems because of high temperature, blowing out of overload initiation.The at present existing technology that solves this problem by the automatic vent decompression is divided into following three classes substantially:
1. increase an outlet valve on wheel newly, when tire internal air pressure superelevation, this valve is opened automatically, thus the venting decompression.For example the patent No. is 02210731.2 " explosion-protection equipment of tyre ", and this scheme only is adapted at adopting when tire plant is made new tyre, is difficult to be applicable to the tire in the existing use.
2. after inflation finishes, the drain tap of on the original valve of tire, screwing on, automatic vent decompression.For example the patent No. is 02254057.1 " tire anti-explosion safety air vavle ".Though this scheme can be used on existing tire, when inflating, drain tap must be backed out, and after inflation finishes, again this valve is backed out, and has increased inconvenience to the car owner at every turn.
3. reach original air faucet of tire of generation with a kind of valve that can serve as inflation and outlet valve simultaneously.For example the patent No. is 200420052005.0 " tire seizing type explosion-proof air valve ".This scheme can not be used for the valve on the existing tire.
The model utility content
The utility model is for solving the deficiencies in the prior art, but use when providing a kind of both air feed mouth factory to make new valve, can be additional to easily on the valve of existing tire for non-specialized-technical personnel again, and possess the exhausted quick-fried valve of Motor Vehicle of inflation and automatic vent decompression simultaneously.
The scheme that solves the utility model technical problem is:
The exhausted quick-fried valve of Motor Vehicle by depression bar, valve body, bonnet, slide block, housing, the bowl of calming the anger, spring, the rubber band of calming the anger, gas shutoff rubber band, seal that gas bowl, combination seal circle, push rod, exhaust port, exhaust are lateral opening, suction port and air outlet form.
Wherein, housing is cylindric, and its end and the former valve of tire to be being threaded, and an other end and valve body are to be threaded.The housing middle part has a separation, suction port and air outlet to lay respectively in this separation.Valve body and depression bar are in active relationship, and its underpart and housing to be being threaded, and its top and bonnet are to be threaded.The lower end of depression bar and slide block are to be threaded.The bar portion of envelope gas bowl and slide block are to be threaded.The bowl of calming the anger is positioned at housing, and its bar portion and slide block are in active relationship, and the oblate post and the housing of its underpart are in active relationship.Slide block is positioned at valve body, and is in active relationship with valve body.Spring is placed in envelope gas bowl and the bar portion of the bowl of calming the anger, and is compressed in slide block and calms the anger between the bowl.Calm the anger that rubber band and gas shutoff rubber band are in envelope gas bowl respectively and the scrobicular ring of the bowl of calming the anger in, and the suction port and the air outlet of sealing housing respectively.The combination seal circle sticks between the annular projection of former air faucet of tire mouth edge and lower housing portion.Push rod is positioned at housing lower end mouth place.
One pore is arranged at the bonnet top.
The depression bar end has screw thread.
The through hole that has exhaust port on the valve body and be in active relationship with depression bar, the same medial axis of this through hole and valve body.The inner diameter that valve body holds Slipper is identical with the inner diameter that housing holds the bowl part of calming the anger.
A side, the air outlet that suction port is adjacent with a gas shutoff rubber band side adjacent with envelope gas rubber band has an annular projection respectively, and it is tighter to be beneficial to sealing.
Have on the slide block exhaust screw lateral opening, that cooperates with envelope gas bowl bar portion, with the screw of depression bar lower end threads engaged and the through hole that is in active relationship with the bar portion of calming the anger bowl.
Push rod is divided into pole socket, the body of rod and rod end three parts, three parts all with the same medial axis of housing.Wherein, pole socket is oblate cylindricality, it with housing to be threaded, through hole is arranged above the pole socket.The rod end diameter is greater than the body of rod.
Spring is the product of maximum safety air pressure in the area of air outlet and the tire to the pressure of the bowl of calming the anger.
The bottom of envelope gas bowl has a groove, inserts for screw-driver.
In the thread pitch of housing and former valve, between gas shutoff rubber band and the envelope gas bowl, the rubber band and calm the anger between the bowl, sealer all arranged between combination seal circle and the housing of calming the anger.
During assembling, the user only need rotate envelope gas bowl, and with regard to the degree that is compressed of adjustable springs, and then Regulation spring is to the pressure of the bowl of calming the anger.
During installation, only need earlier sealer is coated in the former valve mouth outside, the more exhausted quick-fried valve of this Motor Vehicle is screwed on, screw and get final product.Depression bar in the former valve is depressed by push rod at this moment, and the valve of former valve is in open mode, and the bowl of calming the anger seals suction port and air outlet respectively by calm the anger rubber band and gas shutoff rubber band respectively under the elastic force effect of spring with envelope gas bowl.
During for Tyre inflating, screw off bonnet earlier, charging air inlet on the air pump is pressed in valve body oral area of the present utility model, its plunger tip with depression bar to pressing down, bowl moves downward thereby depression bar drives slide block drive envelope gas, the gas shutoff rubber band leaves the annular projection of suction port, and high-pressure air is just successively lateral opening through exhaust port, exhaust, the through hole on the suction port, air outlet, push rod pole socket and the former air faucet of tire of the valve that is opened enter in the tire.
When the tire internal air pressure reached maximum safe air pressure, the bowl of calming the anger moved upward under the effect of tire internal air pressure, and the air in the tire is just discharged from the air outlet.When the tire internal air pressure is reduced to the highest safe air pressure when following, under the effect of spring pressure, the bowl of calming the anger moves downward, and the rubber band of calming the anger is sealed the air outlet.
Adopt such scheme, can receive following effect:
1, the utility model can in time reduce pressure in the tire, stops the accident of blowing out that raises and cause because of the tire internal air pressure effectively.
2, the utility model collection inflation, automatic deflation, three kinds of functions of envelope gas are one, and it not only can be spun on the existing air faucet of tire and use, but also can adopt this scheme (only need save push rod), highly versatile when making new valve.
3, simple installation can be for convenient installation of the amateur personage that repairs.
