Abstract
The utility model relates to an air valve device suitable for the inflation of tyre, comprising an air valve tube and an automatic sealing piece. The sealing part of the air valve tube and an air valve mouth is provided with a sealing groove, and the inner of the groove is provided with a sealing ring. The side wall of the air valve tube is provided with an air outtake mouth. The utility model is characterized in that the automatic sealing piece is a flexible rubber tube which is tightly coated on the air valve tube and the outer end of which appears peak-shaped. The utility model has the advantages of labor saving during inflation, good tightness and easy fabrication.
Description
The utility model relates to a kind of tire valve device.
Existing tire valve device, form the valve one-way valve by vent pipe and the rubber pipe that is enclosed within on its periphery, convex cone face extruding in its rubber tube and the air inlet nozzle forms external sealed, rely on the elasticity of this rubber pipe to make that pressurized gas is unidirectional to enter inside tires and don't gas leakage simultaneously, though this device reaches the purpose of unidirectional air inlet and sealing, but inflate effort and the fragile gas leakage in external sealed place.
The purpose of this utility model is to improve the structure of vent pipe, and the elastic rubber tube that uses special shape as one-way valve from dynamic seal, make inflate laborsaving, good airproof performance.
The purpose of this utility model is realized by following mode.
The door device of saving the strength that the utility model is addressed, include vent pipe and from dynamic seal, there is seal groove at the sealing position of vent pipe and tyre valve, be provided with elastic seal ring in the groove, on the vent pipe sidewall air outlet is arranged, from dynamic seal is the elastic rubber tube that tightly is enclosed within on the vent pipe, the outer end that it is characterized in that elastic rubber tube is bongrace shape, tongue covers on the air outlet, and when inflating, the pressurized gas that enters vent pipe from inflator starts bongrace, enter inside tires, after having beaten gas, the air pressure in the tire is close on the aperture tongue, and is air tight.
Described vent pipe can use metallic material to make, also can be directly injection molded by duroplasts.
Be further described below by accompanying drawing:
Fig. 1 is the vent pipe schematic representation that has bongrace shape sebific duct.Among the figure, 1 is vent pipe, and 2 is exterior seal ring, and 3 is bongrace shape rubber pipe, and tongue covers on the air outlet.
Valve gear of the present utility model, its vent pipe has kept the profile that is complementary with existing valve cock, does not change valve cock, can be directly used on the existing vehicle.It has inflate laborsaving, good airproof performance, and advantage easy to process, with low cost.
