Problems solved by technology

The two valves are connected by pipelines, which is prone to pipeline leakage, posing safety hazards, and there are also unfavorable factors such as high cost and inconvenient after-sales service
[0003] Patent document CN2328543Y discloses a semi-automatic automobile tire inflation nozzle with a rotary movable head, which is connected by an inflation and deflation switch, a curved conduit, a front and rear housing, a connecting bolt, a piston, a sealing rubber ring, a thimble spring, a spring seat, and a one-way valve thimble Composed, the device can conveniently inflate various types of automobile tires, save time and effort, and can semi-automatically clamp, loosen and take out, but cannot realize automatic or manual closing control; document CN2806207Y discloses a multifunctional tire pressure monitoring automatic alarm The device includes a gas injection nozzle and a tubular connection sleeve. There are gas injection conduits and valves between the gas injection nozzle and the tubular connection sleeve. An air pressure balance device is arranged side by side with the gas injection conduit. An alarm is installed on the air pressure balance device to detect in time. Tires cause insufficient air pressure due to air leakage and report to the police, and can be automatically inflated in emergency situations, but the structure is more complicated
There are also separate lock valves and tire valves similar to foreign ones in China, but because they are two valves, the pipeline is long and the structure is relatively complicated, so the inevitable failure rate is high

Abstract

The invention relates to a device which can shut off a single tire automatically or manually when a vehicle tire is inflated and deflated, in particular to a multifunctional valve which can automatically and rapidly shut off a gas circuit when the intake pressure is lower tan certain pressure and is widely applied to cross-country vehicles. The manual automatic tire shut-off valve enables a gas circuit channel to be shut off, can automatically shut off a gas channel between the tire and a rotating sealing air chamber through a spring arranged on the tire valve when the intake pressure is lower than a designed pressure value, can achieve pressure maintaining of the tire, and can achieve inflation, deflation, pressure measuring and pressure maintaining of the tire when the vehicle runs at a low speed.

Description

technical field [0001] The invention relates to a device for automatically or manually shutting off a single tire when the tire is inflated and deflated, especially when the intake pressure is lower than a certain pressure, it can automatically and quickly shut off the air path, and is more widely used in off-road vehicles. Background technique [0002] At present, there are separate lock valves and tire valves in Germany, the United States, etc. The lock valve is used to manually shut off the air channel between the tire and the rotary sealed air chamber; while the tire valve is to automatically shut off the tire and the rotary sealed air chamber by the spring on the tire valve when the intake pressure is lower than the design pressure value. The air passage between them. If the two valves are connected by pipelines, it is prone to pipeline air leakage, which has potential safety hazards, and there are also disadvantages such as high cost and inconvenient after-sales servi...
