Electric eccentric hemispherical valve for wastewater treatment in paper mills

Electric eccentric hemispherical valve for wastewater treatment in paper mills

The electric eccentric hemispherical valve can accurately control the opening of the valve through the control system, and is suitable for chemical wastewater treatment processes that require frequent adjustment of flow rate.

The use of special alloy materials in the sealing pair improves the service life of the valve under high pressure, high temperature, and corrosive medium conditions. Due to its self-cleaning function and high sealing performance, the maintenance frequency of the electric eccentric hemispherical valve is lower, reducing operating costs. The application of electric eccentric hemispherical valves in wastewater treatment of chemical enterprises is mainly reflected in their effective control and regulation capabilities for liquid, gas, and solid mixtures. Suitable for working conditions with high requirements such as petroleum, chemical, urban water supply and drainage, especially in the treatment of wastewater containing particulate matter and prone to sedimentation and scaling, it performs well.

Good sealing performance: Adopting an eccentric structure, the ball can tightly fit with the valve seat when closed, achieving good sealing and small leakage.

Small flow resistance coefficient: After the sphere is opened, the flow resistance of the medium channel is almost small, which can save energy and improve pipeline transportation efficiency.

Long usage time: The ball and valve seat are made of wear-resistant and corrosion-resistant materials, and the eccentric design reduces friction between the ball and valve seat, extending the valve's operating time.

High control accuracy: The electric actuator can accurately control the opening of the valve, meeting the precise requirements for flow control under different working conditions.

High degree of automation: can be remotely controlled, facilitating centralized control and management in industrial automation production processes.

The valve core adopts an eccentric structure. When the ball is opened, it first disengages from the valve seat and then rotates. When it is closed, it rotates first and then seals with the valve seat, reducing friction between the ball and the valve seat and improving sealing performance and service time.

Hemispherical valve core: The valve core is hemispherical, with smooth flow channels and low resistance when the medium passes through, which can effectively reduce energy loss.

Eccentric sphere: It is the core component of the valve, and the sphere adopts an eccentric design. This design allows the sphere to first lift upwards along the eccentric axis when opened, disengage from the valve seat, and then undergo rotational motion; When closing, first rotate to the position close to the valve seat, and then press down on the valve seat to achieve sealing.
