Y ring is a common seal

Y sealing ring is a common seal or oil seal, its cross section is Y shape, so the name. Y-type sealing ring is mainly used for sealing piston, plunger and piston rod in hydraulic system. It has the advantages of simple structure, convenient installation, good self-sealing and strong wear resistance. The material of Y-type sealing ring is generally nitrile rubber, polyurethane, fluorine rubber, etc., according to the different working conditions, you can choose different hardness and color.

Y-type sealing ring specifications and sizes are also a variety of (including seals and oil seals), you can choose the right type according to the size and shape of the groove. Y-type sealing ring has a very wide range of applications, it can be used in a variety of hydraulic equipment, mechanical equipment, automotive parts, engineering machinery, agricultural machinery and other industries. Here are a few examples to illustrate the application of Y-ring seals!

Hydraulic cylinder: Hydraulic cylinder is one of the most important executive components in the hydraulic system (including the oil seal), it can convert hydraulic energy into mechanical energy, to achieve linear movement or swing movement. The hydraulic cylinder has piston and piston rod inside, between them need to have good sealing performance to prevent leakage or pollution of hydraulic oil.

Y-type sealing ring is a commonly used seal in the hydraulic cylinder. It can be installed on the piston or piston rod. According to the direction of movement, it can be divided into one-way sealing and two-way sealing. Y-type sealing ring can withstand high pressure and speed, but also has good wear resistance and self-lubrication, can adapt to a variety of working environments.

Cylinder: Cylinder is one of the most common executive components in pneumatic systems (including oil seal seals), which can convert pneumatic energy into mechanical energy to achieve linear or swinging motion. The cylinder also has pistons and piston rods inside, which also need to have a good seal between them to prevent gas leakage or contamination. Y-type sealing ring is also a commonly used seal and oil seal in the cylinder. It can be installed on the piston or piston rod. According to the direction of movement, it can also be divided into one-way seal and two-way seal. Y-type sealing ring can withstand higher temperature and speed, but also has good aging resistance and chemical resistance, can adapt to a variety of gas medium.

Valve: Valve is one of the most important control components in the fluid control system (including oil seal seals), it can control the flow, direction, pressure and other parameters of the fluid. The valve has a spool and seat inside, and they need to be well sealed between them to prevent fluid leakage or mixing. Y-ring is a commonly used seal in the valve, it can be installed on the spool or the seat, according to the direction of the fluid, can be divided into one-way seal and two-way seal. Y-type sealing ring can withstand high pressure and temperature, but also has good wear resistance and corrosion resistance, can adapt to a variety of fluid media.

Summary – In addition to the Y sealing ring, other types of seals need to be used in the valve, such as oil seals, packing, gaskets, etc. Oil seal is a kind of seal used for rotating or swinging motion parts between the shaft and the shell. It is mainly composed of metal skeleton and rubber lip, which can effectively prevent the leakage of hydraulic oil or other lubricants from the shaft end, and prevent external dust, water and other impurities from entering the bearing interior. Filler is a kind of loose material used to fill the gap between the shaft and the shell. It is mainly composed of fiber, wire, graphite, etc., which can form an adaptive sealing layer under pressure and friction, and has a certain elasticity and plasticity. Gasket is a kind of sheet material used to increase the contact area between two planes. It is mainly composed of metal, rubber, paper, etc., which can compensate for the roughness between two planes and improve the sealing effect.
