Abstract
The utility model discloses a valve inside for tyre underpressure automatic alarm, mostly comprising a valve inside sleeve, a valve inside body and a push rod. The utility model is characterized in that a spring is sleeved on the push rod. Lower end of the spring contacts with a catch which is fixed on the push rod; a seal body is fixed at the lower part of the push rod, and a seal ring is arranged on the seal body. The utility model is simple in structure, low in cost and convenient in usage. The utility model can be combined with an alarm device so as to automatically alarm when the air pressure is low in the tyre.
Description
The utility model relates to a kind of valve inside, the valve inside that particularly a kind of tyre underpressure auto alarm is used.
At present, the valve inside of using on the tire only has the mono-sealing function, and when tire made that because of gas leakage the tire internal gas pressure reduces, people often can not find in time that tire uses, and causes damaged tyres under under-voltage condition, causes a lot of unnecessary economic losses.
The purpose of this utility model just is to provide a kind of valve inside---valve inside that the tyre underpressure auto alarm is used of the usefulness of reporting to the police when tyre underpressure.
Technical solution of the present utility model is: described valve inside mainly is made up of valve core retainer plate, valve core body and push rod etc., the valve inside cover is sleeved on the top of valve inside body, in the inner chamber of valve core body, be provided with push rod, be set with spring on push rod, the lower end of spring contacts with catch on being fixed on push rod; Bottom at push rod is fixed with sealing member, and sealing member is provided with seal ring.
Outside, middle part at the valve core body is set with seal gasket.
The utility model is simple in structure, novel in design, with low cost, easy to use, combine when using with warning device on the tire tube valve, can be when the tire internal gas pressure reduces to certain pressure auto alarm, the tyre injury of having avoided tire to work and caused under under-voltage condition has reduced economic loss.
Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.
Fig. 1 is a main TV structure cross-sectional schematic of the present utility model.
With reference to accompanying drawing, the utility model mainly is made up of valve core retainer plate 1, valve core body 2 and push rod 3 etc., valve core retainer plate 1 is sleeved on the top of valve core body 2, offer the screw thread of the usefulness that is connected with tire tube valve at the upper end of valve core retainer plate 1 outer wall, in the inner chamber of valve core body 2, be provided with push rod 3, be set with spring 4 on push rod 3, the lower end of spring 4 contacts with catch 5 on being fixed on push rod 3, and the upper end is fixed on the valve core body 2; Be fixed with sealing member 6 in the bottom of push rod 3, sealing member 6 is provided with the seal ring 7 that seals.Outside, middle part at valve core body 2 is set with seal gasket 8.
The utility model use that can combine with the warning nut on the tire tube valve.
Principle of work of the present utility model is: when keeping normal barometric pressure in the tire, under the effect of gaseous tension, the sealing member of push rod lower end overcomes the application force of spring, seals the valve core body jointly with seal ring, and gas does not leak outside; When tire is punctured or other damage and produce when gas leakage, when the tire internal gas pressure is reduced to less than spring force, spring reset, make push rod break away from the valve core body, gas flows out by valve inside, and the warning device that is contained on the tire tube valve is reported to the police, reminds people notes tyre underpressure so that timely changing of tire.
