BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1The machine wheel structure with air tightness and one-way conduction ability of the application is shown in the figure. In the figure: 1-machine wheel assembly, 2-valve body sealing ring, 3-valve body seat, 4-end face sealing ring, 5-top rod, 6-shutter, 7-self-locking nut, 8-spring. DETAILED DESCRIPTION

[0010] As Figure 1 shown, a machine wheel structure with air tightness and one-way conduction ability includes machine wheel assembly 1, valve body sealing ring 2, valve body seat 3, end face sealing ring 4, top rod 5, shutter 6, self-locking nut 7 and spring 8. The valve body seat 3 is installed on the machine wheel assembly 1 and is screwed on the machine wheel assembly 1. Both the machine wheel assembly 1 and the valve body seat 3 are provided with fuse holes, and a fuse can be used to prevent loosening to ensure that the valve body seat 3 is stably installed on the machine wheel assembly 1. The machine wheel assembly 1 is provided with an air hole to communicate the inner cavity of the valve body seat 3 with one side of the tire installed on the machine wheel. The outer side of the valve body seat 3 is provided with an interface for connecting other performance components on the machine wheel, such as temperature and pressure sensors, tire pressure sensors, etc. The machine wheel assembly 1 and the valve body seat 3 are provided with the valve body sealing ring 2 to effectively ensure air tightness. The inner cavity of the valve body seat 3 is provided with the top rod 5, the shutter 6 and the spring 8. The inner side of the top rod 5 extends into the inner cavity of the valve body seat 3 through the inner hole of the shutter 6. The outer side shaft shoulder of the top rod 5 abuts against the outer side end face of the shutter 6. The self-locking nut 7 is screwed on the top rod 5 and abuts against the end face of the shutter 6. The spring 8 is sleeved on the outer side of the top rod 5, and the two ends of the spring 8 abut against the shutter 6 and the machine wheel assembly 1 respectively. The shutter 6 is pushed by the spring 8 to tightly abut against the valve body seat 3. The shutter 6 and the valve body seat 3 are cooperated at a tapered surface. The cooperation part of the shutter 6 and the valve body seat 3 is provided with the end face sealing ring 4 to ensure air tightness. The outer side end face of the top rod 5 is located in the interface on the outer side of the valve body. When the components are installed at the interface, pressure is applied to the top rod 5.

[0011] Working principle: The valve body seat 3 is provided with an installation interface for installing other performance components on the machine wheel. The interface on the valve body seat 3 can be adjusted according to the interface requirements of the performance components to improve the installation capacity of the machine wheel. When the temperature and pressure sensors, tire pressure sensors and other components are installed on the valve body seat 3, pressure is applied to the top rod 5. After the top rod 5 is stressed, the shutter 6, the self-locking nut 7 and the end face sealing ring 4 are moved to the inside of the valve body seat 3 to compress the spring 8, so that the shutter 6 is separated from the valve body seat 3, and a gap is generated between them. The air pressure in the machine wheel is communicated with the tire pressure sensor through the gap to realize real-time monitoring of the tire pressure of the aviation machine wheel. When the tire pressure sensor is disassembled, the spring 8 is reset to push the shutter 6, the self-locking nut 7, the end face sealing ring 4 and the top rod 5 to move outward, so that the shutter 6 abuts against the valve body seat 3 to restore the air tightness and realize the air tightness and one-way conduction ability of the aviation machine wheel.

[0012] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
