Abstract
A tyre air valve is provided, wherein a safe pressure limiting safety device is arranged on the lower part of the air valve body; the safe pressure limiting safety device consists of a spring, a pressure limiting valve and an air outlet pipe, which is arranged on the air inlet pipe of the air valve body together with a shaft sleeve; one side of air inlet pipe of the air valve body is provided with the air outlet pipe with the lower end communicated with the air inlet of the tyre and the upper end communicated with the outer wall of the air valve body; the pressure limiting valve is pressed on the air outlet pipe; the flange of the air valve body is formed as a groove; an elastic closing ring is arranged on the groove; the safe pressure limiting safety device is made into a core part and arranged on one side of the air inlet pipe of the air valve body; an adjusting bolt is arranged on the spring. When the tyre is heated because of friction and makes the gas inside the tyre expand close to or beyond the pressure that the tyre can bear, under the action of the gas pressure inside the tyre, the safe pressure limiting safety device presses the spring, and the gas inside the tyre is exhausted out to reduce the pressure inside the tyre, avoiding tyre burst. The use of the elastic closing ensures dustproof effect.
Description
(1) technical field
The utility model relates to a kind of tire valve, belongs to the Tire Inflation System technical field.
(2) background technology
The condition of road surface of China is become better and better at present, and the express highway mileage open to traffic is more and more, makes that the road speed of power actuated vehicle is also more and more higher.In this case, friction generates heat between motor tire of running at high speed and the road surface can aggravate, and summer is particularly serious.Because the motor tire valve does not have safe pressure limiting safety mechanism, when when gases are heated, they expand in the tire when surpassing the pressure that tire can bear, just have the danger of blowing out, consequence is hardly imaginable.Particularly owing to be subjected to the restriction of factors such as technology and condition, the situation of gas overcharging is arranged during tire, the danger meeting of blowing out is bigger.In addition between the dust cap of existing tire valve and the valve body with being threaded, but do not have anti-loosing device, dust cap comes off easily when driving and loses dustproof effect.
(3) summary of the invention
At the deficiencies in the prior art, it is a kind of reasonable in design, simple in structure, easy to manufacture, safe and convenient to use that the utility model provides, and can prevent effectively that motor tire from blowing out and guarantee the tire valve of dustproof effect.
A kind of tire valve, a safe pressure limiting safety device is set in the bottom of valve body, this device is made up of spring, limiting valve and freeing pipe, safe pressure limiting safety device coaxial package is on the air inlet pipe of valve body, the freeing pipe that is provided with in valve body air inlet pipe one side that the lower end is communicated with tire air inlet, is communicated with outside upper end and the valve body wall, freeing pipe is provided with limiting valve, limiting valve by spring application on freeing pipe.
Valve body is provided with flange, and the dust cap of valve body is provided with the elasticity groove.
Valve body is provided with groove, and the dust cap of valve body is provided with elastic flange.
The flange place of valve body can be arranged to a groove, and groove is provided with an elastic collar.
Safe pressure limiting safety device is made a chipware and is installed in a side of the air inlet pipe of valve body, and spring is provided with an adjustable bolt.
During use, the pressure limiting numerical value of limiting valve and the spring above the limiting valve is adjusted at a safety value.In the vehicle ' process, when the gas in the tire that is heated because of friction expands the pressure that can bear near tire, safe pressure limiting safety device is in tire under the gaseous tension effect, spring is compressed, the slit appears between limiting valve and the freeing pipe, gas is released in the tire, and the pressure in the tire reduces gradually, thereby has avoided blowing out.The use of valve body upper flange or flange change the use of elastic collar on the groove of establishing, and have avoided coming off of dust cap effectively, have guaranteed dustproof effect.
The utlity model has reasonable in designly, simple in structure, easy to manufacture, safe and convenient to use, can prevent effectively that motor tire from blowing out and guarantee the characteristics of dustproof effect.
