The V/O type regulating valve has a V/O-shaped opening which is rotated by 180° on the reverse side of the V/O-shaped opening on the front surface of the entire spherical surface. The flow passages of the front and back are smoothly connected, and the flow curve of the flow is different according to the opening size. There can be approximately equal percentages and approximate straight lines.
The flow curve of the V/O type regulating valve can have an approximate equal percentage and an approximate straight line depending on the opening size, so the adjustment performance is good, and since it is a double-sealed two-way pressurized regulating valve, it is pressed in both directions, It can be used under stricter sealing conditions and poorly regulated conditions. It is a combination of V-type valve and O-type regulating valve. It combines the advantages of V-type regulating valve and O-shaped regulating valve to make the angular stroke regulating valve. The scope of use has been expanded.
1. The sealing of the oil cylinder piston should use products of reliable quality to ensure good sealing performance.
2.Before installing the oil cylinder piston seal, the seal and sealing groove should be cleaned to ensure that the sealing surface is free of impurities.
3. When installing the seal, the correct installation sequence and direction should be carried out according to the drawing requirements to ensure the correct installation of the seal.
4.When installing the seal, special tools should be used to avoid using sharp tools and hard objects to damage the seal.
5. When installing the seal, attention should be paid to whether the seal groove is damaged or worn. If so, it should be replaced or repaired in a timely manner.
6. When installing the seal, an appropriate amount of lubricating oil should be applied to avoid friction damage to the seal during installation.
7.When installing the seal, it should be ensured that the compression of the sealing ring meets the requirements to avoid excessive or insufficient compression leading to seal failure.
8.After installing the seal, a sealing test should be conducted to ensure that the sealing performance meets the requirements.
