When the pressure inside the tire is too large, the internal pressure of the tire pushes the ball valve (762) in the first through hole (78) to cause the pressure in the tire to pass through the perforation (10) in the first through hole body (10) (4). The hole U can be designed to have an automatic bubble pressure by the design of the above-mentioned device, but the valve has a complicated structure, a large number of parts, and does not cause the manufacturer to increase the cost of the manufacture when the valve is manufactured. [New content] Structure: This = = Complexity 'So simplifying its knot to reduce costs and the number of Z-loaded components can be reduced, to - Ϊ本二's 'creative automatic shallow-pressure tire valve' includes: One end is hollow, and the other end is 5 M331063 solid, and a pressure relief hole and a plurality of inflation holes are formed thereon, and a perforation is formed on the diameter wall of the valve body, and Fei, Li The orifice and the pressure relief hole are in communication with each other; - the valve is sealingly engaged in the (4) hole of the valve body; and the intake valve is sealingly engaged with the upper end of the valve body. When using the air pump, the air pump will pressurize the top end of the inflation valve. By pressing the air intake valve between the air intake valve and the inflation hole to form a passage to inflate the tire. When the tire is smashed and the force is too large, the pressure inside the tire will push the bleed valve, so that the pressure inside the tire is passed through the hole and the hole in the valve body to complete the pressure. By the above means, by using the special structure of the valve body to match the position of the pressure relief valve and the gas valve, the number of components can be reduced and the construction can be simplified, so as to reduce the cost.

The sealing pad (24) is cylindrical and forms a connecting hole (26) at a center position, and the connecting hole (26) can be sleeved on the connecting post (25). Then, the assembled return spring (22) is placed into the pressure relief hole (12) with the sealing pad (24) facing downward, and then screwed to the inside of the pressure relief hole (12) by the fixing screw (21). On the segment, the return spring (22) element is fixed. The tensile elasticity generated by the reset spring (22) is used to stop the gasket (24) from opening at the bottom end of the pressure relief hole (12) to provide a pressure relief function. The inlet fluorine valve (30) includes a fixed seat (31), an intake seat (π), a gasket (33), a shaft (34) and a return spring (32). The fixing seat (31) is hollow cylindrical, and an inner wall of the upper end is formed with a threaded section to form a screw hole, and a threaded section is formed on the diameter wall of the lower end thereof, and the thread section and the valve body (10) The internal thread of the upper end is matched, and the fixing seat (31) is formed with a threaded section on the radial wall-lower jaw, and the threaded section and the internal thread of the upper half of the valve body (10) are screwed together.

The washer (33) provided on the intake seat (35) can be used to form a valve by using a spring (32) on the shaft (37), and the M331063 and the air inlet seat (35) can be screwed to the fixed seat. (31), the air inlet seat (35) is completely sealed in the fixing seat (31), and the intake valve (3〇) is screwed to the upper end of the valve body (10) after completion, thus completing A tire valve with automatic pressure relief. Please refer to the fourth figure. When the intake valve (30) and the relief valve (2〇) are assembled, the through hole (36) on the intake manifold (30) and the inflation hole on the valve body (1〇). (13) An interconnecting passage is formed between each other, but the through hole (36) and the inflation hole (13) are separated from each other by a gasket (33) of the intake valve (30) between the passages. Please refer to the fifth figure, and the pressure relief hole (丨2) is in communication with the orifice (11) of the valve body (丨〇), and the pressure relief hole (丨2) and the perforation (丨丨) are The pressure relief hole (12) and the perforation (11) are isolated from each other by a gasket (24).
