Electric ball valve model preparation/code name designation method in China.
As an important equipment in the industrial automation control system, the electric ball valve has been used more and more in recent years due to its simple structure and convenient operation. It can not only be used to cut off or connect the medium in the pipeline, but also can be used for fluid Regulation and control! But because of the different working conditions of the pipeline, the electric ball valve models used are all different! The user should have a detailed understanding and cognition of the method of preparing the electric ball valve model!
This electric ball valve model editing method includes the addition of additional conditions for the ball valve, the selection of the drive mode, the different connection form, the change of the structure form, the type of sealing material, the level of the valve pressure and the valve body material, etc.!
Electric ball valve model representation method:
Ball valve additional code:
V means the spool has a V-shaped structure, D means low temperature, B means heat preservation, P means eccentric structure, U, S and DY mostly mean top-mounted type;
Ball valve name code: Q means ball valve; Ball valve drive code: 2 means electro-hydraulic, 3 means turbine, 6 means pneumatic, 7 means hydraulic, 9 means electric, manual without code;
Code of connection method: 1 means internal thread, 4 means flange type, 6 means welding, 7 means wafer type;
Structure type code:
