Semi eccentric ball valves are suitable for situations that require strict standards such as sewage treatment, paper oars, alumina, and urban heating; Suitable for controlling power plants, hydraulic slag removal or gas pipelines.Structural types of eccentric ball valves.
There are two types of eccentric ball valves in terms of appearance and structure:
1)Upper mounted: mainly designed for media with severe erosion and wear. The replacement and maintenance of damaged opening and closing components in the upper structure is very convenient, without the need to remove the entire gate valve from the pipeline, greatly saving maintenance time and costs.
2)Side mounted: The side mounted structure is compact, lightweight, and suitable for places with requirements for valve installation space.
Characteristics of eccentric ball valves
1)The eccentric semi ball valve is a top mounted structure.
2)The eccentric semi ball valve is designed as a single seat. Eliminated the problem of abnormal pressure rise in the medium inside the valve chamber, which affects safety and reliability.
3)Low torque design. The specially designed valve seat can be easily opened and closed with just a small handle.
4)There is no friction when opening and closing. This feature completely solves the problem of traditional [wiki] gate valve [/wiki] protrusions rubbing against each other and affecting sealing.
5)Wedge shaped sealing structure.
6)Self cleaning structure of eccentric semi ball valve protrusion. When the ball tilts away from the valve seat, the liquid in the pipeline passes uniformly 360¡ãalong the convex surface of the ball, which not only eliminates the local flushing of high-speed liquid on the valve seat, but also washes away the deposition on the convex surface, thus achieving the purpose of self-cleaning.
The application scope of eccentric ball valves:
Eccentric ball valve products are particularly suitable for media such as steel industry, aluminum industry, fibers, fine solid particles, paper oars, coal ash and petroleum gas.
1)Suitable for situations with strict requirements such as sewage treatment, paper oars, and urban heating.
2)Suitable for weak corrosion and two-phase mixed flow media in petroleum, heavy oil and other oil products, chemical industry.
3)Suitable for the transportation control of gases, natural gas, and liquefied gas.
4)Suitable for industrial pipeline transportation with chemical changes containing crystallization or scaling in liquid-solid two-phase mixed flow or liquid transportation.
5)Suitable for controlling power plants, hydraulic slag removal or gas pipelines. |
