What is the role of Jinhua electric wafer type fluorine lined butterfly valve in HVAC? The key parts to add lubrication and injection are: the inner cavity wall of the cylinder, the piston seal ring, the gear strip and the back annular plate. A certain amount of grease should also be added to the gear shaft and seal ring. After adding grease to the pneumatic butterfly valve, it needs to be installed in the reverse order of disassembly and components. After installation, it needs to be installed in the reverse direction of disassembly and components. During installation, there are some matters that need special attention. Pay attention to the assembly position of the gear strip to ensure that when the valve is opened, The piston can quickly move to the innermost position of the cylinder.
、 5. Since materials such as polytetrafluoroethylene have good self-lubricating property and small friction loss with the ball, the service life of pneumatic ball valve is long.
