    Tips: Reasons for water leakage of large diameter sanitary butterfly valve

    Large-diameter sanitary butterfly valves sometimes leak water during use. Because they have relatively large specifications, you should be paid to them during installation and maintenance. However, what are the reasons for the leakage of large diameter sanitary BF valves?

    Problems of the butterfly valve itself. The anti-corrosion layer of the gate and the gate body falls off or the anti-corrosion layer is thin, causing the gate body and the gate to rust, and the thickness of the gate can be up to 30-50 mm, causing the valve to be lax. The sealing rubber ring has quality defects, and the installation is not firm or the thickness is too thin, which causes the sealing rubber ring to fall off during the operation of the brake.

    Hydraulic reasons in butterfly valve operation. Generally, the pressure of the large-diameter pipe network is above 30 meters, and the butterfly valve has to withstand greater pressure during the opening and closing process. The sudden action changes the water flow state, and the butterfly valve is closed from closing. In the state, it gradually opens to form a gap. The shear force generated by the water flow acts on the gate, cutting the edge of the gate. Repeated action may cause the rubber ring to fall off or break, and the gate will be gaped, and the valve will be loose. The phenomenon. Long-term immobility and improper maintenance of the butterfly valve cause difficulty in operating the butterfly valve.
