What is butterfly valve worm gear box? What is the function of worm gear box?

The worm gear box of Henan Xinfu Valve Manufacturing Co., Ltd. is often used in the occasions of staggered two axes, large transmission ratio, small transmission power or intermittent work. The worm drive of the worm gear box is used when the two axes are crossed at 90 degrees, but when they are not parallel or intersecting, the worm is usually the active part of the worm gear drive, and the worm wheel is the passive part.

Worm gear box as the main equipment of pipeline valve, its function is similar to worm gear head, is a device used to drive and adjust the valve. The box is driven by an external drive, and the connecting parts of the box are connected with the internal parts of the valve, so the worm gear box is equivalent to driving the valve to adjust the internal medium of the pipeline, which is the main application of the worm gear box at present.

The valve stem of worm gear box is an important part of the valve at present, it controls the valve core operation of the valve, and can also play the role of transferring the external handle and the actuator. It can be said that it plays the role of "intermediary", as another kind of rod - worm gear rod, in fact, its role is similar. The main function is to better adjust the interior of the worm gear box, and has a certain transmission effect, which is the main function of the worm gear rod at present.

Worm gear box worm drive has the following characteristics:

1, compact structure, and can obtain a larger transmission ratio, the general transmission ratio of 7-80.

2, stable work without noise.

3. Wide range of transmission power.

4, can self-lock.
