Main components of electric butterfly valve
In our daily life, there are four common flange sealing methods for the end and adapter plate of electric butterfly valve: JBF, GF, HF and ZF.
The ordinary electric butterfly valve is a kind of curved capsule composed of, and net wire, commonly known as pneumatic tube, corrugated pneumatic tube, leather tiger, etc. The two ends of the capsule shall be connected with two steel plates to form a compressed air chamber. The cable itself does not provide the load bearing capacity, but is completed by the compressed air filled into the capsule. The number of curved capsules is usually 1-3, but it can also be designed to form 4 or more than 5 curved capsules according to the demand, and it can also be used by superposition of two electric butterfly valves under certain conditions.
The electric butterfly valve is also called as air stroke conditioner and air vibration isolator according to its performance and characteristics. The end structure of the existing curved bag electric butterfly valve can be divided into three categories according to the connection mode:
One is the fixed flange connection type. The edge size of both ends of the electric butterfly valve is equal to or slightly smaller than the maximum outer diameter of the curved capsule. After drilling several holes, use the blue ring and the end plate to fasten the connection;
The other is the looper flange connection type. The size of the edges at both ends of the electric butterfly valve is much smaller than the maximum outer diameter of the curved capsule, and there is no need to drill holes. A special flange ring and an ordinary end plate are used to fasten the connection;
The third type is a self sealing type, which is not connected by flange, but is pressed into the end plate and self sealed when compressed air is filled.
In fact, we must be able to see a lot of valve installations similar to electric butterfly valves in our life. Today's article on this topic will be shared with you here. Thank you for your reading!
