Butterfly valve use should pay attention to the details
The wafer butterfly valve is especially suitable for places with narrow space or short distance between pipes. When the butterfly valve is fully opened, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure generated by the valve can be reduced very little, so it has good flow control characteristics. To explain to you under the wafer type butterfly valve before installation pay attention to what matters.
wafer type butterfly valve placement before the meticulous incident
1. Before the placement and operation, the external objects on the piping shall be cleaned by atmospheric spraying, and the inner surface of the piping shall be washed and cleaned with clean water.
2, carefully check whether the use of the valve environment and its performance example; (temperature, pressure)
3, check the valve channel and sealing surface for debris, and real-time cleaning;
4. After unpacking, the valve should be placed in real time. Do not rotate any fastening screws or nuts on the valve at will.
5. The wafer butterfly valve must use a special butterfly valve flange.
6. The electric butterfly valve can be placed on pipelines with arbitrary angles. For the convenience of maintenance, do not place it upside down.
7, butterfly valve flange in the installation must ensure that the flange surface and the sealing rubber in the center, screw tightening evenly, butterfly valve sealing surface must be a complete fit; If there is a screw tightening force is not uniform, there will be a rubber bump stuck butterfly plate phenomenon, or against the butterfly valve butterfly plate to cause leakage at the valve stem.
