Abstract

The utility model discloses a tyre threshold valve, comprising a valve body, a valve block, a spring, an inner core and a rubber mouth. The inner core (5) is arranged on an inner tube of a tyre, the whole is arranged in the valve body, and an air outlet hole (51) is arranged on the inner core; the inner core air outlet hole (51) is sealed by the rubber mouth (4), an air outlet (11) is also arranged on the valve body (1), and a slide block (3) is closed on a column-shaped passage between a valve body air outlet (11) and the inner core (5); the back end of the slide block is provided with a spring (2). When the inner air pressure of the tyre is too strong, the valve can realize loading is automatically discharged.

Description

Tire threshold value valve

The utility model relates to the automatic drain charge valve of a kind of tire superpressure.

Tire causes the tire internal gas pressure excessive under the motion of high temperature or fierceness sometimes, causes the tire blast, and existing valve can not be released automatically to inner pressure of tire, the balance tyre inner pressure.

The purpose of this utility model is a kind of threshold value valve of design, and when tyre inner pressure surpassed certain value, the gas of releasing out automatically guaranteed that pressure is unlikely excessive.

The utility model comprises valve body, valve piece, spring, inner core and rubber mouth, inner core (5) is loaded on the tire inner tube, its integral body is in valve body, air gate (51) is arranged on inner core, inner core air gate (51) is sealed by rubber mouth (4), air gate (11) is also arranged on the valve body (1), sealed by slide block (3) on the cylindrical passageway between valve body air gate (11) and the inner core (5), there is spring (2) the slide block rear end.When the tire internal gas pressure is excessive, gas draws back sealing of rubber mouth (5), enter valve body by rubber mouth outlet (6), if pressure greater than spring (2), then push slide block until exposing air gate (11), too much gas is by air gate (11) drain charge in the tire, and therefore, the utility model has been realized the drain charge effect that tire pressure is excessive.

Accompanying drawing is the utility model structural representation;

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

Valve body is fixed on the inner tube of a tyre (7), and inner core (5) communicates with tire gas, goes up at spring (2) to also have a spring fixed column (21).When the tire internal gas pressure was excessive, gas drew back sealing of rubber mouth (5), entered valve body by rubber mouth outlet (6), as if the pressure greater than spring (2), then pushed slide block until exposing air gate (11), and too much gas is by air gate (11) drain charge in the tire.Tire pressure just often, slide block is subjected to the effect sealing air gate (11) of spring (2), rubber mouth (5) also seals the air gate of inner core (5).By two place's adjusting knurl air pressure, thereby reach reasonable effect.

Claims

1, a kind of tire threshold value valve, comprise valve body, valve piece, spring, inner core and rubber mouth, it is characterized in that inner core (5) is loaded on the tire inner tube, its integral body is in valve body, air gate (51) is arranged on inner core, and inner core air gate (51) is sealed by rubber mouth (4), and air gate (11) is also arranged on the valve body (1), sealed by slide block (3) on the cylindrical passageway between valve body air gate (11) and the inner core (5), there is spring (2) the slide block rear end.
