1. The valve should be placed in a ventilated and relatively dry chamber, and both ends of the valve passage should be blocked. Both pneumatic ball valves and pneumatic butterfly valves need to be kept dry.
2. If it is stored for a long time, it should be checked regularly and cleaned regularly. After cleaning, it should be coated with anti-rust oil.
3. After installation, we must also regularly check whether the valve is working properly and the degree of aging. The main inspection items include: (1) The wear of the sealing surface; (2) The wear of the trapezoidal thread of the valve stem and the valve stem nut; (3) Whether the packing is outdated and invalid, if it is damaged, it should be replaced in time; (4) Valve maintenance and assembly After that, the sealing performance test should be carried out. If it is a flanged valve such as a pneumatic flanged butterfly valve, the connection of the flange should also be paid attention to.
The valve should also be injected with grease regularly, so that it can be used for a longer time, which can make the valve function normally and increase its service life.
When injecting grease, do not ignore the quality of grease. The quality of grease is very important. Some greases not only have no protective effect on the valve, but may also have side effects. Therefore, when choosing grease, try to choose better grease. When injecting grease into the valve, it should be injected according to different valve sizes and instructions. It can be calculated according to the size and capacity of the valve, and then an appropriate amount of injection is performed.
