The role and principle of the valve glance box

The main function of the valve gluten box is to convert the high -speed rotation of the motor to the output of low -speed and high -torque, thereby realizing the opening and closing of the valve. Law

The working principle of the valve gear box involves multiple key components and processes. First, the motor drives the snail rotation, the worm is messed with the worm wheel, and the high -speed rotation of the motor is converted into the rotation motion of the worm wheel. The worm is connected to the valve stem, and the valve stem drives the valve core to move, thereby realizing the opening and closing of the valve. In this process, the structure of the valve turbine is relatively simple, easy to maintain, and has high transmission efficiency and large torque output.

Specifically, the valve gear box is mainly composed of the following parts:

Support : Supported worm wheels, worms and other components.

worm wheel: meshing with the worm, converting the rotation of the worm into a rotation movement.

worm: driven by motor, meshing with the worm wheels.

Bearing: It is used to support parts such as worm wheels, worms.

Sealing parts: It is used to prevent lubricating oil leakage.

Through the coordinated work of these components, the valve gear box can efficiently control the switch of the valve, and it is suitable for various industrial and civilian scenarios that need to accurately control fluid flows.
