Description
Technical field
This practical vehicle tyre deflation warning system that relates to, particularly a kind of loss of tyre pressure sentinel valve.
Background technology
Automobile in the process of moving, owing to the interference of road conditions reason or other factors, gas leak phenomenon takes place in tire often, continues operation as automobile, tire can be scrapped very soon, very easily causes a serious accident.The lorry of truck and band trailer particularly, its trailing wheel mostly is the twin tire structure, and when one of them tire flat, chaufeur is difficult in time finding, and like this, it is quick-fried gently then another can be taken turns tire pressure, heavy then may lead to traffic accident.At present, some electronics, mechanical tire alarm device also occur, but all existed shortcomings such as complex structure, cost height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of loss of tyre pressure sentinel valve that can in time report to the police automatically when tire flat.
Integral structure of the present utility model is:
This loss of tyre pressure sentinel valve, comprise tire tube valve 9, valve seat 8, valve body 2, valve rod 11, valve plate 13, the compression spring 4 and the whistle 1, wherein the two ends of valve seat 8 are tapped bore, one end connects with tire tube valve 9, the other end connects with valve body 2 lower ends, be provided with through hole in valve seat 8 and the valve body 2, be provided with limit dais 14 in the valve seat 8, limit dais 14 is fixedly connected with valve seat 2, limit dais 14 is provided with and valve plate 13 corresponding protruding 6 towards a side of valve plate 2, be provided with valve rod 11 in the through hole of valve seat 8 and valve body 2, valve rod 11 nearly limit daiss 14 places are provided with and the valve rod 11 fastening valve plates that connect 13, on the valve rod 11 on valve plate 13 tops, be set with compression spring 4, be provided with baffle plate 5 in the valve body 2,10, baffle plate 5,10 are fixedly connected with valve body, and the center-hole diameter of baffle plate 5 is greater than compression spring 4 diameters, the center-hole diameter of baffle plate 10 is less than compression spring 4 diameters and greater than valve rod 11 diameters, and valve body 2 upper ends are located at the whistle 1.
Concrete structure of the present utility model also has:
Have air extractor vent 15 on the described limit dais 14.
Have air extractor vent 3 on the described baffle plate 10.
Described valve seat 8 is provided with packing seal 7 with valve body 2 connection places.
Described baffle plate 5 is towards the fastening packing seal 12 that is connected with of a side of valve plate 13.
The cross-sectional plane outline of described valve seat 8 is the circle of square or flat mouthful of hexagon.
The obtained technological advance of the utility model is:
The utility model can be automatically to tyre leakage play accurately, warning effect timely, and simple and reasonable for structure, with low cost, be suitable for applying.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
As shown in the figure, valve seat 8 lower inside have negative thread, with tire tube valve 9 thread connection, valve seat 8 tops have outside thread, and with valve body 2 thread connection, the centre hole that centers on limit dais 14 is evenly equipped with three projectioies 6 and three air extractor vents 15, valve rod 11 is formed in one with valve plate 13, be evenly equipped with three air extractor vents 3 around the centre hole of baffle plate 10, this compression spring 4 adopts the stage clip that is slightly less than motor tire standard pressure when normally moving, and the outer contour shape of valve seat 8 cross-sectional planes is a hexagon.
Condition of service of the present utility model is as described below:
During use, standard pressure as the tire internal gas pressure during more than or equal to normal operation, then valve plate 13 moves to baffle plate 5 directions, until closing, when tire flat or other situation cause the tire internal gas pressure to be lower than compression spring 4 setting pressures, spring 4 effects by compression, valve plate 13 is opened, to the operation of positioning plate 14 directions, until withstanding on the projection 6, at this moment, air-flow is through limit dais air extractor vent 15 in the tire, the limit dais centre hole, baffle plate 5 centre holes, baffle plate 10 air extractor vents 3, baffle plate 10 centre holes, after the whistle 1 discharge, send caution sound, remind chaufeur to note, in time adopt remedial measures.
