Structure and maintenance of four types of butterfly valves: electric butterfly valve, clamp butterfly valve, turbine butterfly valve, and flange butterfly valve
Delcofluid valve manufacturer is committed to providing customers with high-quality butterfly valve products. Today, we will provide a detailed analysis of the structural characteristics and maintenance guidelines of four butterfly valves: electric butterfly valve, clamp center line butterfly valve, clamp turbine center line butterfly valve, and flange turbine center line butterfly valve.
1、DELCO Electric butterfly valve
(1) Electric butterfly valves have become the preferred choice for commercial buildings, public buildings, and urban water or ventilation systems due to their convenient control methods and wide application fields.
① The extended valve neck design not only facilitates installation and insulation, but also effectively reduces the impact of fluid heat on the driver.
② The soft seal design adopts a nylon 11 coated arc-shaped sealing edge butterfly plate, which has good self-lubricating properties, low operating torque, and low leakage rate.
③ The groove type valve seat design ensures smooth operation of the valve plate, requires low torque, and effectively prevents valve seat deformation and detachment.
(2) In terms of maintenance, electric butterfly valves mainly focus on the condition of the electric actuator and the wear of the sealing ring.
① Regularly check the power supply, torque, and operating time of the electric actuator to ensure that it is in good working condition.
② At the same time, check whether the sealing ring is aging or worn, and replace it in a timely manner to ensure sealing performance.
2、DELCO Clamp centerline butterfly valve and clamp turbine centerline butterfly valve
(1) Both butterfly valves adopt a vulcanized backrest type valve seat design, suitable for isolation or adjustment in pipelines.
① The high-quality valve plate ensures that the valve has a quick closing function, and the high-precision fit of the valve shaft and disc makes the opening and closing of the valve easier.
② In terms of material selection, both the valve body and valve plate are made of ductile iron, the sealing ring is made of EPDM, the valve shaft is made of stainless steel, and the O-ring is made of nitrile rubber, ensuring stable operation of the valve within the temperature range of -10~80 ℃.
(2) During maintenance
① Check the wear of the valve shaft and gearbox, and replace severely worn components in a timely manner.
② At the same time, check whether the sealing ring is aging or damaged to ensure its sealing performance.
③ For turbine driven butterfly valves, it is also necessary to check the lubrication inside the turbine box and regularly add or replace lubricating oil.
3、 DELCO Flange turbine centerline butterfly valve
(1) The flange turbine centerline butterfly valve adopts a centerline design, with a simple structure and good bidirectional sealing effect.
① The valve seat adopts a rubber lining structure, which has low flow and pollution resistance, low switching torque, and easy maintenance.
② This butterfly valve is widely used in fluid pipelines such as drinking water, water supply and drainage, wastewater, water treatment, buildings, fire protection systems, etc., as a regulating and intercepting device.
(2) In terms of maintenance
① Regularly check the fastening of flange connections to ensure no leaks.
② At the same time, check the wear of the valve shaft, turbine box, and sealing ring, and replace severely worn components in a timely manner.
③ For rubber lined valve seats, it is also necessary to pay attention to their aging condition and replace them if necessary.
Summary
The four butterfly valves provided each have their own characteristics and are suitable for different application scenarios. During use, it is necessary to select the appropriate butterfly valve model according to specific working conditions and strictly follow the operating procedures for operation and maintenance. Regularly inspect the various components of the butterfly valve, promptly identify and address potential issues, and ensure the stable operation and extended service life of the butterfly valve.
