Product features

The electric telescopic butterfly valve is mainly composed of the electric actuator and the flange telescopic butterfly valve. The so-called telescopic butterfly valve is to assemble an expansion device with the same diameter as the butterfly valve on the original basis of the butterfly valve. The structural features of the electric telescopic butterfly valve not only facilitate the disassembly of the valve, but also relieve the pipeline stress, and at the same time, it can eliminate the internal force caused by the temperature difference, and compensate for the thermal expansion and cold contraction caused by the temperature difference of the pipeline. The electric flange expansion butterfly valve can be installed at any position. It is mainly used to control the switch cutoff of pipeline medium, and also can be used to regulate the flow.
 
Application of electric telescopic butterfly valve:
 
The electric telescopic butterfly valve can be divided into ordinary type, fixed limit type and extended type, which is suitable for working conditions with temperature ≤ 80 ℃ and pressure ≤ 1.6MPa, and adopts flange connection. It is generally used in electric power, metallurgy, petroleum, chemical industry, gas and solid powder pipelines for adjustment and cutting off, and has the function of compensating the expansion and contraction of pipelines.

Design standard of electric telescopic butterfly valve:
 
Design standard: GB/T12238-1989; JB/T8527-1997
Flange connection size:
GB/T9113.1-2000； GB/T9113.2-2000；
GB/T9115.1-2000； GB/T9115.2-2000
Structure length: GB/T12221-1989
Pressure test: GB/T13927-1992; JB/T9092-1999
1. It can produce axial displacement (elongation, compression) when used on pipes.
2. It can be used on the pipeline to reduce vibration and transmission noise of the structure.
3. The valve is used on the pipeline and is not restricted by the pipeline within the specified range.
4. It is free from the restriction of flange parallelism, and can be installed at will, with light weight and good elasticity.
 

Structural advantages of electric telescopic butterfly valve:

The structure length of the electric flange telescopic butterfly valve can be adjusted within a certain range when the valve is installed, which can also relieve the pipeline stress and protect the valve. In addition, the installation is not affected by the medium and flow direction, and the installation mode of butterfly valve and expansion device is concentrated, so the space is more compact. Generally, the electric telescopic butterfly valve does not need special maintenance, but only needs to regularly observe whether there is leakage and pulling off of its telescopic part.
