What is high and low pressure cylinder Y seal ring?

High and low pressure cylinder Y seal ring is also known as bud seal ring, is developed on the basis of Y seal ring, high pressure cylinder Y seal ring by Y seal ring and rubber ring in the lip after pressing and bonding into a one-way solid seal ring, the working pressure can reach 60MPa, the pressure is less than 30MPa without a stop ring. It is suitable for sealing device for reciprocating movement of high and low pressure cylinder piston rod, and can also be used for static sealing device of flange end cover

First, high and low pressure cylinder Y seal ring use:

Hole: Used for sealing piston in reciprocating high and low pressure cylinder 

Shaft: Used for sealing piston rod in reciprocating high and low pressure cylinder

Material: Ding Qing rubber hardness HS75A°

Fluorine rubber hardness HS80A°

Polyurethane hardness HS85A° 

Clip fabric rubber hardness HS95A°

Operating temperature: -40℃~+120℃

Working pressure: ≤32Mpa Bud ring ≤50Mpa

Working medium: hydraulic oil, compressed air, water

Standard source: GB10708.1-89 

Groove conforms to: GB2879-86

Customization: Can be customized

Two, the advantages of high and low pressure cylinder Y seal ring:

The Y-type sealing ring of the high and low pressure cylinder is developed on the basis of the Y-type sealing ring, so the advantages compared with it are

(1) The selection of different materials in the upper and lower parts makes the sealing and pressure parts perfectly combined. 

(2) The high hardness of the rubber fabric, so that it can both increase the sealing pressure and textile squeeze into the gap.
