As we all know, the oil tank is a very important part of the car, which provides power for the car. The car will walk with the oil. It is because of this that the importance of the oil tank can be imagined. As we all know, according to the different structure of automobile oil tank, oil tank can be divided into bite type oil tank, aluminum alloy type oil tank, CO2 welding type oil tank, upper and lower butt type oil tank, two end seam welding type oil tank.
Gas tank cap
Gas tank covers are usually designed to be clamped with claw type and the rubber gasket pressed by the spring of the wave sheet is clamped around the edge of the gasoline tank mouth to ensure sealing. Some of the covers are also designed with a deadlock device to prevent falling off or losing. In order to ensure the balance of pressure in the tank, the air valve and steam valve are designed on the tank cover. Because the two valves are designed as one, they are also called composite valves. When the gasoline in the box is reduced and the pressure is reduced to below 96KPA, the air valve is opened by atmospheric pressure, and the outside air enters the tank to balance the vacuum in the box to ensure the normal supply of gasoline; When the steam and steam pressure in the box is greater than 107. At 8KPA, the steam valve is pushed open and the steam is discharged into the atmosphere (or into the carbon tank for vehicles with fuel evaporation control devices). To keep the pressure in the tank normal, thus ensuring stable pressure from the oil to the carburetor.
