The Industrial valve is the necessary control and adjustment part inside of pneumatic actuators, and in order to make sure the normal running of the Industrial valve, it is necessary to lay emphasis on the Industrial valve maintenance period.
In the use of electric industrial butterfly valve, the use environment is often damaged due to leakage problems, so preventing leakage is an important problem that needs to be solved by electric butterfly valves. Introduce several methods that can effectively solve the leakage of electric butterfly valves.
The driving mode of swing check valve is automatic, the connection mode can be selected from flange, clip type, welding, thread, structure can be selected with swing type, sealing structure can be selected with PTFE, PPL, hard seal, pressure range PN10~ PN160, the nominal diameter is DN15-1200mm, the material can be selected from WCB, 304, 316, alloy steel and so on.
The triple offset butterfly valve has a slanting circular shape (the third eccentricity of the so-called triple eccentricity) except that the wide rod and the valve plate have two eccentricities.
The valve stem axis simultaneously deviates from the disc center and the body center, and the valve seat turns the axis and the valve body channel axis has certain Angle, is called the Triple offset butterfly valve
The butterfly plate of the soft seal butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°.
The two eccentricities of the double offset butterfly valve refer to the eccentricity of the rotating center line of the disc and the eccentricity of the sealing line and the eccentricity of the center line of rotation of the disc and the center line of the channel.
Further improved molding on the basis of the single offset butterfly valve is currently the most widely used double offset butterfly valve. The structural feature is that the stem axis is offset from the center of the disc and from the center of the body.
The butterfly valve has a small flow resistance when fully opened. When the opening is between about 15° and 70°, sensitive flow control is possible, so the application of butterfly valves is very common in the field of large-diameter adjustment.
The butterfly valve is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium refers to a valve in which the closing part (the valve flap or the butterfly disc) is a disc and rotates around the valve shaft to open and close.
