Description
Technical field
The utility model relates to the motor vehicle fittings field, particularly relates to a kind of Motor Vehicle general anti-explosion nausea mouth.
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 provides a kind of and is additional to easily on the valve that has tire now for non-specialized-technical personnel for solving the deficiencies in the prior art, and possesses the Motor Vehicle general anti-explosion nausea mouth of inflation and automatic vent decompression simultaneously.
The scheme that solves the utility model technical problem is:
Motor Vehicle general anti-explosion nausea mouth is by depression bar, air spring, demarcation strip, push-type gas spring, the bowl of calming the anger, the mouth body, envelope gas rubber band, air passing hole, envelope gas bowl, push rod, the combination seal circle, vent, making leaf spring and mouth cap constitute, it is characterized in that: the mouth body is the inner cylinder that a separation is arranged, on its inner separation an air passing hole is arranged, the bowl of calming the anger is positioned at the air passing hole top, envelope gas rubber band sticks in the circular groove of the bowl bottom of calming the anger, envelope gas bowl is arranged in air passing hole, envelope gas bowl be positioned at the depression bar lower end and with depression bar be an integral body, depression bar is in also can be up and down in the through hole at calm the anger bowl and demarcation strip middle part, demarcation strip be arranged in the mouth body and with the mouth body to be threaded, making leaf spring is positioned at the depression bar top and is connected with welding manner with depression bar, push rod is in the inside, lower end of mouth body, and with the mouth body to be threaded, air spring be placed on the depression bar and be in making leaf spring and demarcation strip between, push-type gas spring is placed on the depression bar and is in demarcation strip and calms the anger between the bowl, the mouth cap sleeve in mouth body upper oral part and with the mouth body to be threaded, the combination seal circle sticks on the ring-shaped step of inside, mouth body lower end.
Wherein, making leaf spring is the tinsel of diameter greater than depression bar, air passing hole upper edge and envelope gas bowl top edge all have a circle conical surface projection, there is a pore in mouth crown portion, calm the anger the bowl the side and mouth body inboard between leave the gap, on the outer wall of mouth body upper oral part and the mouth body inwall screw thread is arranged all, the push rod upper end is oblate cylindricality, and there is the screw thread that matches with mouth body internal whorl this oblate post side, and the edge has the hole, push-type gas spring is to the elastic force F=PS+f of the bowl of calming the anger, wherein, P is the maximum safety air pressure in the tire, and S is the horizontal projected area of air passing hole, f is the elastic force of air spring to making leaf spring, and this elastic force is identical with the elastic force of common valve medi-spring in valve inside.
During use, only need be spun on the mouth body to tighten on the former valve mouth tube and get final product.At this moment, push rod pushes up the press rods in the former valve downwards, makes the valve of former valve be in opening state, and the air in the tire promptly enters in the mouth body, and is sealed in the space of mouth body bottom by envelope gas rubber band and envelope gas bowl.
The action of inflating by the utility model is with identical by traditional valve inflation action, when the projection of the pneumatic head of air compressor pushes away depression bar downwards, the stage clip dish compresses air spring, the top edge of envelope gas bowl leaves envelope gas rubber band, form ring-like slit, Air Compressor slit thus enters tire.Envelope gas bowl top edge pressed envelope gas rubber band again after inflation finished under the effect of air spring, and air is sealed.
Reach the maximum safe gas pressure of this tire when the tire internal air pressure after, high-pressure air promotes envelope gas bowl and envelope gas rubber band moves upward, air passing hole is opened, air is discharged by air passing hole in the tire, when atmospheric pressure in the tire is reduced to maximum safe air pressure when following, the downward bowl that promotes to calm the anger of push-type gas spring makes envelope gas rubber band be close to the tapered protrusion of air passing hole upper edge again, and air is sealed once more in the tire.
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 can be spun on the existing air faucet of tire and use highly versatile.
3, simple installation, the amateur personage of repairing need not that original valve is done any repacking just can directly use the utility model.
