Description
Technical field
The utility model relates to the motor vehicle fittings field, particularly relates to a kind of Motor Vehicle tire explosion proof valve.
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 Motor Vehicle tire explosion proof valve of inflation and automatic vent decompression simultaneously.
The scheme that solves the utility model technical problem is:
The Motor Vehicle tire explosion proof valve comprises: with the mouth body of former valve mouth tube to be threaded, be in the mouth body and with the demarcation strip of mouth body to be threaded, with mouth body upper oral part to be threaded and to have the mouth cap of pore, the middle part is arranged in the air passing hole of mouth body, top covers air passing hole, the lower end is pressed in band pipe on the envelope gas rubber band in the envelope gas bowl bowl of calming the anger, stick at calm the anger the rubber band of calming the anger in the bowl of band pipe, run through demarcation strip with the band pipe calm the anger the bowl depression bar, the stage clip dish in aggregates and that be in active relationship with mouth body inwall with depression bar, be placed on the depression bar, air spring between stage clip dish and demarcation strip, be placed on the depression bar, the band pipe calm the anger the bowl and demarcation strip between push-type gas spring, be positioned at mouth body bottom, and with the push rod of mouth body to be threaded, be in mouth body and former valve mouth nozzle junction and stick at seal ring on the horizontal annular platform of mouth body bottom, with the depression bar lower end with the envelope gas bowl that is threaded and stick at envelope gas rubber band in the envelope gas bowl upper surface ring shaped slot.
Wherein, the inclined-plane that the upper edge of the air passing hole at mouth body middle part has a circle to raise up, mouth body inner and outer diameter suitable for reading is identical with former valve mouth tube, there is the through hole of a diameter greater than the depression bar diameter at the band pipe bowl center of calming the anger, the band pipe bowl top of calming the anger is the oblate cylinder of a diameter greater than its underpart, this oblate cylinder bottom surface exceeds on the ring surface of bottom a circular groove, the rubber band of calming the anger sticks at wherein, there is a tapering band pipe bowl lower end of calming the anger, envelope gas bowl bottom central authorities have one flat mouthful of groove, the demarcation strip center has the hole that is in active relationship with depression bar, this next door, hole has vent, air spring is identical with the elastic force that traditional valve medi-spring is produced to the elastic force of depression bar, push-type gas spring is to the calm the anger elastic force F=PS+f of bowl of band pipe, and wherein, P is the maximum safety air pressure in the tire, S is the calm the anger horizontal projected area in the space between the bowl of the band pipe in air passing hole inwall and the hole, and f is the elastic force of air spring to depression bar.
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 the rubber band of being calmed the anger is sealed in the space of mouth body bottom with envelope gas rubber band.
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, envelope gas rubber band is left in the calm the anger lower end of bowl of band pipe, form ring-like slit, the air of inflator slit thus enters tire.The inflation back envelope gas rubber band that finishes is close to the calm the anger lower end of bowl of band pipe again under the effect of air spring, air is sealed.
Reach the maximum safe gas pressure of this tire when the tire internal air pressure after, high-pressure air promotes the band pipe bowl of calming the anger and moves upward, the rubber band of calming the anger leaves the end of air passing hole ring-like ramp projections suitable for reading, form a ring-like slit, air is discharged in the slit thus in the tire, when atmospheric pressure in the tire is reduced to maximum safe air pressure when following, push-type gas spring promotes downwards to make the rubber band of calming the anger be close to the end of air passing hole ring-like ramp projections suitable for reading again with the pipe bowl of calming the anger, 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 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, the amateur personage of repairing need not that original valve is done any repacking just can directly use the utility model.
