Valve assembly for tire pressure sensing

Abstract

The invention is a valve assembly for tire pressure sensing, which includes: a base body, which is provided with a circuit board and an air pressure chamber communicated with the circuit board; and the assembly part of the base body has a first flow channel communicated with the air pressure chamber; a valve joint, the two ends of which are respectively assembled with the valve and the assembly part, and has a second flow channel inside; the inner wall of the valve joint has an internal thread section and the outer wall has an air guide hole, the air guide hole is connected with the second flow channel and the first flow channel respectively; the adapter is locked on the valve joint The inner and outer walls have an external threaded section that locks the internal threaded section of the valve joint, and there is an air guide flow channel connected with the air guide hole between the external thread section and the internal thread section; When the base body is locked on the valve stem of the valve through the adapter, part of the gas generated by the valve flows into the second flow channel, flows through the air guide hole, flows into the first flow channel through the air guide hole, and then flows into the air pressure chamber through the first flow channel, allowing the circuit board to sense the gas state of the air pressure chamber.
