Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valve stem processing equipment, in particular to a hydraulic valve stem PVD / PCVD composite coating processing equipment. Background Art

[0002] The hydraulic valve stem is an important part of the valve, used for transmission, connected to the actuator or handle, and directly drives the valve core to move or rotate to achieve the valve opening or adjustment. It is generally a cylinder or a cylinder with straight grooves on the surface. The valve stem is not only a moving part and a force-bearing part during the opening and closing of the valve, but also a sealing part. At the same time, it is impacted and corroded by the medium, and also produces friction with the packing. Therefore, when selecting the valve stem material, it must be ensured that it has sufficient strength, good impact toughness, abrasion resistance, and corrosion resistance at the specified temperature. The valve stem is a wearing part, and attention should also be paid to the material's machining performance and heat treatment performance when selecting it.

[0003] The hydraulic valve stems currently produced have very high requirements for size, shape and position tolerance, and surface treatment. The above requirements are combined to ensure that the hydraulic valve stem can precisely match the valve body during operation to form a seal. At the same time, high surface hardness is also a guarantee of product service life. At present, the surface of the hydraulic valve stem is processed with PVD / PCVD coating to meet the processing accuracy requirements, which is difficult to meet the use requirements of the hydraulic valve stem. The hydraulic valve stem needs to be polished when the surface layer is processed, but the existing polishing belt cannot be adjusted and cannot be used for multiple hydraulic valve stems to work together, which is inefficient.
