In the daily production process, as a commonly used equipment, the wiper of the pneumatic actuator of the V-type control valve needs to be replaced. The actuator in the V-type control valve is easy to wear excessively. If it is not replaced in time, it may affect the efficiency of the work. Therefore, we can use the rubber diaphragm of the same specification to replace it when replacing it.

In the daily production process, as a commonly used equipment, the wiper of the pneumatic actuator of the V-type control valve needs to be replaced. The actuator in the V-type control valve is easy to wear excessively. If it is not replaced in time, it may affect the efficiency of the work. Therefore, we can use the rubber diaphragm of the same specification to replace it when replacing it. After the fastening process In order to make the force of the grinding plate more uniform and prevent leakage or crushing of the diaphragm, today I will talk to you about the V-shaped regulating valve and some main contents of its accessories in the process of daily maintenance. Help everyone better understand the V-shaped control valve.

The valve seat and the valve core of the V-shaped regulating valve are prone to leakage after a certain period of operation, and the wear between the piston of the cylinder and the cylinder body will also cause internal leakage. At this time, we can properly For grinding work, mechanical grinding, manual grinding, coating treatment or inlaying methods can be used. The strength of the diamond used in the grinding process must be appropriate, and the grinding force must be uniform. And the valve seat is polished to meet the required joint degree and precision requirements, and to meet the requirements for the valve seat and valve core to be centered. After the installation is completed, it needs to be tested for tightness.

When replacing the stuffing box of the V-shaped control valve, the same type of stuffing box should be used. During the replacement process, everyone must carefully pull out the stuffing to remove the paint correctly and avoid damage to the V-shaped control valve. The valve stem causes certain damage. When installing a new stuffing box, everyone should follow the instructions in the manual, and the cut should be misplaced. This is to prevent the thread of the valve stem from scratching the packing, and the compression degree of the stop material should be uniform and smooth. drop to avoid increased friction and stress.

Replacement of transmission parts. If the transmission parts in the V-shaped regulating valve and accessories are partially worn, parts can be replaced and repaired. After replacement and repair, the transmission should be flexible and the transmission gap should be as small as possible. Pneumatic amplifier cleaning. When the orifice of the pneumatic amplifier is blocked due to the dirt in the instrument compressed air, the orifice should be cleaned, and a suitable steel wire can be used for dredging and cleaning. When reassembling, the amplifier diaphragm should be stressed evenly to prevent clogging or leakage. The amplifier gain can be adjusted by adjusting the pressing force of the steel ball to prevent resonance.

After reading the above content, all the readers here must have a clear understanding of the daily maintenance content of the V-shaped control valve. I hope this article can be helpful to you.
