What adjustments are required before installing electric butterfly valves, clamp butterfly valves, turbine butterfly valves, and flange butterfly valves
In industrial fluid control systems, butterfly valves play an indispensable role as important control components. Both the intelligent control of electric butterfly valves and the widespread application of clamp butterfly valves, turbine butterfly valves, and flange butterfly valves demonstrate the importance of butterfly valves in pipeline systems. As a valve manufacturer, Delcofluid understands the importance of making appropriate adjustments and preparations before installing these butterfly valves.
This article will provide a detailed introduction to the various adjustments required before installation.
1、Adjustment before installation of electric butterfly valve
Electric butterfly valves have become the preferred choice in commercial buildings, public buildings, and urban pipelines due to their flexible control methods and wide range of applications. Before installing the electric butterfly valve, special attention should be paid to the following adjustments:
(1) Selection of actuator: Choose the appropriate switch type or adjustable type actuator according to actual needs. Ensure that the torque of the actuator matches the specifications of the valve to ensure reliable operation of the valve.
(2) Power connection: Confirm that the power connection of the electric actuator is correct, the voltage fluctuation range should be within ± 10%, and the frequency should meet the standard of 50/60Hz.
(3) Signal testing: For intelligent actuators, signal testing is required to ensure the normal transmission of input signals (such as switch signals, 4-20mA) and output signals (such as passive signals, 4-20mA).
(4) Insulation and protection: Considering the temperature environment that electric butterfly valves may face, insulation measures should be taken during installation to reduce the impact of fluid heat on the driver. At the same time, ensure that the protection level of the actuator reaches IP67 to cope with harsh working conditions.
2、Adjustment before installation of clamp butterfly valve and turbine butterfly valve
Butterfly valves and turbine butterfly valves are widely used in various pipeline systems due to their compact structure and sealing performance. Before installation, the following points should be noted:
(1) Valve seat inspection: Ensure that the sulfurized backrest design of the valve seat is intact, without damage or deformation. This helps to achieve rapid closure and stable sealing of the valve.
(2) Valve shaft and disc fit: Check the high-precision fit between the valve shaft and disc to ensure that the valve can be easily opened and closed through a high-quality gearbox.
(3) Sealing ring installation: The sealing ring (such as EPDM material) should be correctly installed between the valve seat and the valve plate to ensure good sealing effect.
(4) Temperature and pressure calibration: Confirm that the operating temperature range and nominal pressure of the valve are consistent with the system design requirements to avoid malfunctions caused by overheating or overpressure.
3、Adjustment before installation of flange butterfly valve
Flange butterfly valves are widely used in fire protection, water supply and drainage systems due to their simple structure and good bidirectional sealing effect. Before installation, the following points should be noted:
(1) Flange connection: Check whether the connecting bolts of the flange are complete and tightened to ensure the sealing of the flange connection surface.
(2) Rubber lined valve seat inspection: Confirm that the rubber lined structure of the valve seat is intact, without damage or detachment, to ensure good sealing effect and fluid permeability.
(3) Switching torque test: Before installation, a switching torque test can be conducted to ensure that the opening and closing torque of the valve meets the design requirements and avoid damage caused by excessive torque after installation.
(4) Medium adaptability: Confirm the compatibility between the valve material (such as ductile iron valve body, EPDM sealing ring) and the conveyed medium to avoid leakage or damage caused by medium corrosion.
Epilogue
Delcofluid knows the importance of adjusting butterfly valves before installation, so it provides detailed guidance and suggestions. By making reasonable adjustments and preparations, the butterfly valve can be ensured to operate stably after installation, improving the overall efficiency and safety of the pipeline system.
