Valve parts grease maintenance

Professional maintenance before and after valve welding plays a vital role in the production and operation of valve parts. Correct, orderly, and effective maintenance will protect valve parts and enable valve parts to work normally. Extend the service life of the valve. The maintenance of valve parts may seem simple, but it is not. There are often overlooked aspects of work. Next, let us take a look at valve parts grease maintenance.

When injecting grease into valve parts, the problem of the amount of grease injection is often ignored

The operator selects the valve parts and the grease injection connection method and then performs the grease injection operation. There are two situations: On the one hand, the valve parts are filled with less grease, the valve parts are not filled with enough grease, and the valve parts sealing surface is accelerated due to insufficient lubricant. On the other hand, injecting too much grease into valve parts will cause waste. It is that the sealing ability of different gate valve parts is not accurately calculated according to the type of valve parts. The sealing capacity can be calculated according to the size and type of valve parts, and then a reasonable amount of grease can be injected.

When injecting grease into valve parts, pressure problems are often overlooked

During the grease injection operation of valve parts, the grease injection pressure of valve parts changes regularly between peaks and valleys. If the grease injection pressure of valve parts is too low, the valve parts will leak or fail. If the pressure is too high, the grease injection port will be blocked, the valve sealant will become hard, or the sealing ring will jam the valve ball or valve plate. Generally, when the grease injection pressure of the valve is too low, the grease injection mostly flows to the bottom of the valve cavity, which is more common in small gate valves. If the grease injection pressure at the valve is too high, check the grease injection nozzle on the one hand. If the grease hole of the valve part is blocked, replace it; on the other hand, if the valve grease becomes hard, use cleaning fluid to repeatedly soften the failed valve seal grease and inject new grease to replace it. In addition, the sealing type and sealing material of the valve parts will also affect the grease injection pressure. Different sealing forms of valve parts have different grease injection pressures. Generally, the injection pressure of valve parts for hard seals is higher than that for soft seals.
