Wafer Soft Seal Butterfly Valve
The thickness of the electric wafer butterfly valve is thinner than that of the flange butterfly valve. There are no flanges at both ends of the valve body, only a few guide bolt holes. The valve is connected to the flange at the pipe end with a set of bolts/nuts, which is generally applicable Suitable for places with narrow space or restricted pipelines. The advantage is that it is easier to disassemble, the valve cost is lower, and it takes up less space. However, the disadvantage is that if there is a problem with one sealing surface, both sealing surfaces have to be disassembled!
Before installing the wafer butterfly valve, it must be laid flat first. Remember not to bump it at will. After pulling it to the installation length during installation, it is not allowed to design the on-site pipeline without special permission. Disassemble the wafer butterfly valve at will, this is what we need to know before installation. At the same time, everyone also needs to know that the wafer butterfly valve can be installed in any position, but after the wafer butterfly valve is installed, it is necessary to lay the butterfly valve along the line and make a bracket for the wafer butterfly valve. Once the bracket is made, it is used It is strictly prohibited to remove the bracket during this time.
Industry Application
Structure Principle Of Butterfly Valve
Butterfly valve (also known as flap valve) is a regulating valve with a circular valve disc or disc as the closing part. It is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical, with short axial length and built-in butterfly plate. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open.
