The big role of small body——let us talk about those things about the valve
As the only component of the car's contact with the ground, the importance of the tire to the safety of the vehicle is self-evident. For a tire, in addition to the solid structure of the tire crown, belt layer, curtain layer, and airtight layer, do you think that the invisible valve also plays an important role in driving safety. The role? If you don't know much about small valves, don't worry, today we will talk to you about the valves.
■About introduction of valve
The valve is a one-way valve for charging and discharging the gas in the tire and maintaining the air pressure in the tire. The tires used in automobiles today are all linerless tires. In terms of structure, the valve and the tire are separated from each other, and the valve is mounted on the rim to play its role.
Although the valve is small, it can be divided into a valve body (base), a gasket, a gasket, a fastening nut, a valve core, a valve cap, and each part is also Has its own role.
The valve body (base) is the only way for gas to enter the tire, while accommodating and protecting the valve core; the fastening nut is known by its name to make the valve and the rim more stable; The gasket of different materials is matched with the fastening nut; the rubber gasket acts as a seal on the inside of the rim to prevent air leakage; the valve cap that is often lost can avoid the foreign body from invading the valve. The secondary sealing of the valve is achieved; while the valve core ensures the gas is smoothly injected into the tire, it also has the function of preventing gas from leaking out.
■ Different materials of the valve
After the introduction of the valve, the following is the key content of today, we will introduce the characteristics of different material valves. Yes, as different metal materials are applied to all aspects of automotive components, the valve is no longer a single rubber material. Metal materials have been widely used in valves, and in the current market, zinc alloy, copper, Valves made of three aluminum alloys are the most common.
■ Valve installation
The valve can be assembled into a screw-on type, a press-fit type and a snap-on type. For example, the assembly of the rubber valve is a snap type, and the valve base is provided with a card slot for fixing with the rim, which also causes a one-time use of the valve, and once removed, it cannot be reused. The metal valve is screw-fitted, and the valve is fixed by a gasket and a fastening nut, and can be reused after being removed.
