The V-shaped sealing ring is a one-way sealing device, which belongs to the range of a lip seal. The V-shaped sealing ring mainly has two materials, one is pure rubber material, and the other is fabric rubber material. Among them, pure rubber material is used. The main use of nitrile rubber and neoprene is the most commonly used, and can also be used in combination or superimposed when the working pressure is high. The highest working pressure of the V-shaped sealing ring can reach 60mpa, and the best straightening temperature is between -30~80℃. The working speed of rubber material is 0.02~0.3m/s, and the cloth material is 0.005~0.5m/Ss. ,-Generally suitable for piston rod and piston seal in high pressure hydraulic equipment. The correct installation of the V-shaped seal ringFor mechanical equipment that is not dedicated, the assembly of the V-shaped seal ring does not require special preparatory work. It is very simple and clear. Compared with the Y-shaped seal ring, it does not require installation chamfering. No other structural measures are needed. When assembling, you only need to extend the V-shaped sealing ring by 20%, and then put it on the shaft or push washer. hurt. The adjustment of the adjusting ring of the V-shaped sealing ring is more important than the installation. After the V-shaped ring is used for a period of time, the lips will wear out. In order to ensure the durability of the dense ring, the tight pressure must be adjusted in time. Therefore, the adjustment of the tight pressure of the V-shaped sealing ring is a problem that should be considered in the design. Generally, the method of adjusting the gasket is adopted. After the thickness and number of the gasket are given, the adjustment can be accurately controlled. The spring is adjusted. If the diameter is less than 60mm, a conical spring should be used. If the diameter is greater than 60m, multiple small springs should be used for adjustment. The cavity where the spring and the V-shaped sealing ring are installed should have good matching accuracy and coaxiality.
