Release Time：2020-06-15
Maintenance method 1, the valve should be placed in a ventilated and relatively dry indoor, the valve passage at both ends to be blocked. 2. If the storage time is relatively long, it should be checked regularly and cleaned regularly. After cleaning, anti-rust oil should be applied. After installation, we must also regularly check whether the valve is normal and the degree of aging. The main inspection items include:(1) the sealing surface wear. (2) the valve stem and stem nut trapezoidal thread wear. (3) Whether the packing is outdated and invalid, if damaged, it should be replaced in time. (4) After the valve is overhauled and assembled, the sealing performance test shall be carried out. The valve should also be filled with grease regularly.
Maintenance method
1. The valve should be placed in a ventilated and relatively dry room, and both ends of the valve passage should be blocked.
2. If the storage time is relatively long, it should be checked regularly and cleaned regularly. After cleaning, anti-rust oil should be applied.
After installation, we must also regularly check whether the valve is normal and the degree of aging. The main inspection items include:
(1) the sealing surface wear.
(2) the valve stem and stem nut trapezoidal thread wear.
(3) Whether the packing is outdated and invalid, if damaged, it should be replaced in time.
(4) After the valve is overhauled and assembled, the sealing performance test shall be carried out.
The valve should also be injected into the grease regularly, so that it can be used for a longer time. Correct and orderly maintenance and maintenance of the valve can make the valve function normally and increase its service life.
The first: in the injection of grease, tend to ignore the quality of grease, grease quality is very important, some grease not only on the valve no protection, there may be side effects, so in the choice of grease, as far as possible to choose grease better. How much is injected into the valve? If less is injected, the sealing surface will wear out due to lack of lubricant. Injecting more grease will cause the valve to block, affect the normal work, but also cause waste of grease, when injecting grease into the valve, it should be injected according to different valve sizes and instructions, which can be calculated according to the size, size and capacity of the valve, and then inject the right amount.
Second: when injecting grease into the valve, the pressure problem is often ignored. If the pressure is too low during injection, it will lead to sealing or failure. If the pressure is too high, the grease injection port will be easily blocked.
