Information

For forged steel valves, attention should be paid to the problems of valve body drainage and thread plugging pressure relief. After the valve pressure test, the gas and moisture in the valve cavity of the sealed cavity will increase in pressure due to the increase in ambient temperature. When grease is injected, the pressure must be discharged first to facilitate the smooth progress of the grease injection. After grease injection, the air and moisture in the sealed cavity should be fully replaced. Timely release of the valve cavity pressure can also ensure the safety of the valve. After the grease injection, be sure to tighten the drain and pressure relief plug to prevent accidents. When injecting grease, pay attention to the problem of uniform grease output. In normal grease injection, the grease outlet closest to the grease injection port first discharges the grease, then to the low point, and finally to the high point, and the grease is discharged one by one. If you do not follow the rules or do not produce fat, it proves that there is a blockage, and clear it up in time.
