TWS Valve Reminder
Butterfly valve installation environment
Installation environment: Butterfly valves can be used indoors or outdoors, but in corrosive media and places that are prone to rust, the corresponding material combination should be used. For special working conditions, please consult Zhongzhi Valve.
Installation site: Installed in a place where it can be operated safely and is easy to maintain, inspect and repair.
Surrounding environment: temperature -20℃~+70℃, humidity below 90%RH. Before installation, first check whether the valve meets the requirements of the working conditions according to the nameplate mark on the valve. Note: Butterfly valves do not have the ability to resist high pressure differences. Do not allow butterfly valves to open or continue to flow under high pressure differences.
Butterfly valve before installation
Before installation, please remove the dirt and oxide scale and other sundries in the pipeline. When installing, please pay attention to make the medium flow direction consistent with the flow direction arrow marked on the valve body.
Align the center of the front and rear piping, make the flange joints parallel, and tighten the screws evenly. Be careful not to have excessive piping stress on the cylinder control valve for the pneumatic butterfly valve.
Precautions for butterfly valve maintenance
Daily inspection: check for leaks, abnormal noise, vibration, etc.
Periodic inspection: Regularly check valves and other system components for leakage, corrosion and jamming, and maintain, clean, dust and remove residual stains, etc.
Disassembly inspection: The valve should be disassembled and overhauled regularly. During the disassembly and overhaul, the parts should be washed again, foreign matter, stains and rust spots should be removed, the damaged or worn gaskets and packings should be replaced, and the sealing surface should be corrected. After the overhaul, the valve should be re-tested by hydraulic pressure. , can be reused after passing the test.
