Electric worm side mounted eccentric hemispherical valve

CBQ941H electric side mounted eccentric half globe valve

CBQ941H adopts electric drive, worm gear reduction transmission, and side mounted eccentric hemispherical structure. The series size range is DN50-DN2000, and the material options include WCB, CF8, and CF8M. The actual standards and material configurations will be confirmed according to the specific order.

The function of worm gear transmission

Worm or worm gear reduction mechanisms are used to transmit rotational motion and obtain the required output torque, and should not be described as uniformly converting rotational motion into linear motion. The specific transmission ratio and required torque should be determined based on the valve diameter, working pressure difference, and sealing structure.

What are the characteristics of an eccentric hemisphere structure?

The eccentric structure can create a specific contact and disengagement relationship between the ball crown and valve seat during the opening and closing process, but the actual wear, sealing level, allowable pressure difference, and adjustment performance still depend on the specific product design, and absolute descriptions such as "no wear" and "extremely high precision" are not used.

Is it suitable for continuous adjustment?

It cannot be deemed suitable for continuous adjustment solely based on the use of electric actuators or eccentric hemispherical structures. If the project requires flow regulation, the shape of the ball crown, valve seat, flow characteristics, allowable pressure difference, and actuator configuration should be verified.

Frequently Asked Questions

Does the worm mechanism convert rotational motion into linear motion?

As an angular stroke hemispherical valve, this product should be understood as deceleration and torque transmission according to the actual transmission mechanism, and cannot be described using a universal linear transmission template.

Is a large-diameter eccentric hemispherical valve necessarily suitable for adjustment?

Not necessarily, it needs to be confirmed based on flow characteristics, pressure difference, sealing structure, and actuator configuration.

Can PN16, Class150, and 10K be directly interchangeable?

No, we need to check the flange, material, and pressure temperature ratings separately.
