Embodiment Construction
[0013] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0014] like figure 1 , figure 2 and image 3 As shown, a vehicle tire inflation and deflation valve of the present invention includes an inflation nozzle 1, a valve core 2, a screw plug 3, a nut 4, a limit plate 5, a sealing ring 1 6, a sealing ring 2 7, a sealing ring 3 8, Backing plate 9, spring 10, sealing ring four 11 and rubber seat 12. The inflation and deflation valve 13 is installed on the rim 14 designed with a built-in air passage through a screw plug 3 . The inflation and deflation valve 13 communicates with the built-in air channel on the rim 14, and inflates the inner cavity of the tire 15 through the built-in air channel.
[0015] The inflation nozzle 1 is the main passage of gas, and one end of the inflation nozzle 1 is provided with a threaded joint connected to an external inflation tool, and the valve core 2 is...

The invention relates to a vehicle tire inflation and deflation valve. The inflation and deflation valve comprises an inflation nozzle (1), a valve core (2), a plug (3), a nut (4), a limiting plate (5), a base plate (9), a spring (10) and a rubber base (12). The valve core (2) is fixed in a central hole at one end of the inflating nozzle (1), a spherical plug at the other end of the inflating nozzle is slidably mounted in a conical central hole at one end of the rubber base (12), a central blind hole of the inflating nozzle (1) serves as an axial air passage, a radial air passage is arranged on the inflating nozzle (1), the axial air passage communicates with a radial air passage, the radial air passage communicates with a tire inner cavity through a rim built-in air passage; and the nut (4 sleeved the plug (3) and fixed to the plug (3), the other end of the plug (3) is fixedly connected with the nut, and the base plate (9) and the spring (10) sequentially sleeve the middle of the periphery of the inflating valve (1). According to the vehicle tire inflation and deflation valve, two-way inflation and deflation are achieved, and the technical problems that an existing tire inflationvalve is too large in size and poor in universality and reliability are solved.
Description
technical field [0001] The invention belongs to the technical field of vehicle tires, in particular to a vehicle tire inflation and deflation valve. Background technique [0002] Inflation and deflation valves are widely used in various wheeled vehicles to inflate and deflate tires and ensure the pressure maintaining performance of tires. With the development of the central inflation and deflation function of wheeled vehicles, the demand and requirements for the inflation and deflation valve with dual air inlets are higher. [0003] Most of the existing two-way tire inflation and deflation valves in China are large in size, and most of them are installed on the surface of the rim, requiring additional design of protective covers and connecting parts such as pipelines. When the vehicle needs to pass through narrow spaces such as bridge holes and aircraft doors, the inflation and deflation valve is often the position with the largest vehicle width, which limits the passabilit...
