Abstract

The utility model discloses an alarm of automobile tire anti-explosive valve core, which comprises tow parts, i.e. a valve core and a deflation alarm. The valve core comprises a solenoid, a solenoid connecting valve body, an export orifice inside the valve in which a sealing air plugging is arranged, a sealing air ring outside the valve, a fine adjustor arranged in the solenoid, a piston rod in the fine adjustor, a piston connected with the inside of the piston rod which is connected with the sealing air plugging, and a spring arranged on the piston rod in the fine adjustor. And the deflation alarm comprises a whistle and a constant pressure valve which is arranged outside of the valve core, an import orifice opened on the valve body, a guide rod in the body, and a spring on the guide rod. The utility model can sound the alarm and deflate automatically in the case of overpressure, therefore being safe and reliable.

Description

Motor tire anti-explosion air valve annunciator

The utility model relates to a kind of valve inside, specifically is a kind of motor tire anti-explosion air valve annunciator.

Present anti-explosion air valve, function is more single, can only report to the police, and can't hear as warning, can not be by oneself.

The purpose of this utility model is to provide a kind of motor tire anti-explosion air valve annunciator, and it is reported to the police when tyre pressure is higher than rated pressure, loses heart automatically simultaneously, and is safe and reliable.

The technical solution of the utility model is as follows:

This device is made of the valve inside and the disappointing two parts of reporting to the police, valve inside is that a screwed pipe is arranged, and the inner end of screwed pipe connects a valve body, and there is air extractor duct the valve body inner end, there is envelope gas stifled in the air extractor duct, the outside of this valve body is with the envelope compression ring, and cover one ditty has piston rod to pass in the above-mentioned screwed pipe in the ditty, the inner end of this bar connects piston, it is stifled that piston even seals gas, is with spring on the ditty inner piston rod, and an end of spring withstands on the piston; The above-mentioned warning and the part of losing heart are that a whistle and constant pressure valve are arranged, constant pressure valve is in the outer end of valve inside, the valve body of this valve has admission port to be communicated with the valve inside inner chamber, guide rod is arranged in the valve body, be with spring on the guide rod, lower end of the guide rod is with safety cap, on the cap inner guide packing ring is arranged, valve body has air extractor duct, and the pars subfrontalis sulci cinguli of valve body has leakage port, and close gas nut is arranged at valve body top; Above-mentioned whistle body is connected with valve nozzle, and the admission port at the whistle is communicated with the air extractor duct of above-mentioned constant pressure valve, and the outer end of whistle body has the whistle stifled, above the vocal cords of the whistle body cover of dust is arranged.

Advantage of the present utility model is: 1, this installs both gas sealings, and can under the situation of superpressure, report to the police again and lose heart automatically, one-object-many-purposes, safe and reliable.2, compact conformation, scientific and reasonable.3, cost is low, and is practical, is easy to promote.

Fig. 1 is the utility model embodiment cross-sectional view

Fig. 2 is that the utility model embodiment screwed pipe and ditty revolve and turn 90 degrees generalized section.

The utility model is described in further detail below in conjunction with accompanying drawing.

Can see by Fig. 1, Fig. 2, this device is made of the valve inside and the disappointing two parts of reporting to the police, valve inside is that a screwed pipe (6) is arranged, the inner end of screwed pipe is buckled on the groove of valve body (5) (25), there is air extractor duct (26) the valve body inner end, envelope gas stifled (1) is arranged in the air extractor duct, there is envelope compression ring (4) outside of this valve, cover one ditty (7) has piston rod (24) to pass in the above-mentioned screwed pipe in the ditty, and the inner end of this bar connects piston (2), piston heads on envelope gas stifled (1), be with spring (3) on the ditty inner piston rod, an end of spring withstands on the piston, and (9) are close air cushion;

Reporting to the police and losing heart partly is on whistle body (14), whistle body is connected in the outer end of valve nozzle (8) with screw thread, the outer end of constant pressure valve valve inside on the body of the whistle, the valve body of this valve (11) connects whistle body with screw thread, there is admission port (22) to be communicated with on the valve body with the valve inside inner chamber, the lower end of valve body connects whistle body, and guide rod (18) is arranged in the valve body, is with spring (17) on the guide rod, the lower end of spring withstands on the body of the whistle, lower end of the guide rod is with safety cap (19), and safety cap joins with the whistle body portion that valve body lower end is connected in the lower end of valve body, packing ring (20) is arranged on the cap inner guide, valve body has air extractor duct (16), and leakage port (21) is arranged at the bottom of valve body, and close gas nut (10) is arranged at valve body top; There is gas sealing ring (23) upper end in the junction of valve body and whistle body; The admission port at the above-mentioned whistle (15) is communicated with the air extractor duct (16) of constant pressure valve, and the outer end of whistle body has the whistle to block up (13), and cover of dust (12) is arranged above the pars stridulans of whistle body (27).

Arrive cruising air pressure to automobile inflating during use, this valve inside is tightened in the sub-chamber of valve nozzle with the tire key gets final product, when the air pressure in the tire surpasses given air pressure, spring (3) is compressed, envelope gas is stifled to outer displacement, air-flow enters the constant pressure valve and the whistle through the gap around the air extractor duct piston rod, when air-flow reaches certain pressure, push cover of dust open, air-flow makes whistle sounding, reminds chaufeur to note slowing down, the spring of constant pressure valve is in the effect lower compression of air-flow at this moment, guide rod moves down, and makes safety cap and whistle body gapped, and gas is got rid of through leakage port by this gap.Treat that the air pressure in the tire recovers normal, under normal barometric pressure, the spring reset of constant pressure valve, the spring of valve inside also resets, and is in the envelope gaseity.
