About Y-ring
Y-ring is a common seal or oil seal with a Y-shaped cross-section, hence the name. Linde told you that Y-rings are mainly used for the sealing of pistons, plungers and piston rods in hydraulic systems, which have the advantages of simple structure, easy installation, good self-sealing and strong wear resistance. The material of Y-type sealing ring is generally nitrile rubber, polyurethane, fluoroelastomer, etc., according to different working conditions, different hardness and color can be selected.
Y-rings are available in a variety of sizes and sizes (including seals and oil seals), and the appropriate model can be selected according to the size and shape of the groove. The application field of Y-ring sealing ring is very extensive, it can be used in various hydraulic equipment, mechanical equipment, auto parts, construction machinery, agricultural machinery and other industries. Let’s give a few examples to illustrate the application of Y-rings!
Hydraulic cylinders
The hydraulic cylinder is one of the most important actuators in the hydraulic system (including the oil seal seal), which can convert the hydraulic energy into mechanical energy to achieve linear or oscillating motion. There are pistons and piston rods inside the hydraulic cylinder, and good sealing performance is required between them to prevent hydraulic oil leakage or contamination.
Y-ring seal is a kind of seal commonly used in hydraulic cylinder, it can be installed on the piston or piston rod, according to the direction of movement, can be divided into one-way seal and two-way seal. Y-rings can withstand high pressure and speed, but also have good wear resistance and self-lubrication, and can adapt to various working environments.
cylinder
The cylinder is one of the most common actuators in pneumatic systems (including oil seal seals), which converts air pressure energy into mechanical energy for linear or oscillating motion. There are also pistons and piston rods inside the cylinder, and good sealing performance between them is also required to prevent gas leakage or contamination. Y-ring seal is also a kind of seal and oil seal commonly used in cylinders, it can be installed on the piston or piston rod, according to the direction of movement, can also be divided into one-way seal and two-way seal. Y-rings can withstand high temperatures and speeds, but also have good aging and chemical resistance, and can adapt to a variety of gaseous media.
valve
The valve is one of the most important control elements in the fluid control system (including oil seal seals), which can control the flow, direction, pressure and other parameters of the fluid. The valve has a spool and a seat inside, and good sealing performance is required between them to prevent fluid leakage or mixing. Y-ring seal is a kind of seal commonly used in valves, it can be installed on the spool or valve seat, according to the different fluid direction, can be divided into one-way seal and two-way seal. Y-rings can withstand high pressures and temperatures, but also have good wear and corrosion resistance, and can adapt to a variety of fluid media.
summary
In addition to Y-rings, other types of seals such as oil seals, packings, gaskets, etc. are required in the valve. Oil seal is a kind of seal used for rotating or swinging motion between the shaft and the housing, which is mainly composed of a metal skeleton and a rubber lip, which can effectively prevent hydraulic oil or other lubricants from leaking from the shaft end, and prevent impurities such as external dust and water from entering the bearing.
Filler is a loose material used to fill the gap between the shaft and the shell, which is mainly composed of fibers, wires, graphite, etc., which can form an adaptive sealing layer under pressure and friction, and has certain elasticity and plasticity. Gasket is a thin sheet material used to increase the contact area between two planes, which is mainly composed of metal, rubber, paper, etc., which can compensate for the unevenness between the two planes and improve the sealing effect.
