Structure and working principle of plug-in valve

? ? slide gate valveIt is a valve used to control the direction and velocity of fluid flow. Its structural composition mainly includes a valve body, an insert plate, a valve stem, and a driving device. It has the characteristics of easy operation and easy maintenance. Plug in valves can be applied to various pipeline systems.

The working principle of a plug valve is to use the rotation of the plug plate inside the valve body to change the on/off and flow rate of the fluid.

When the plug is perpendicular to the direction of fluid flow, the valve closes and the fluid cannot pass through.

When the plug is parallel to the direction of fluid flow, the valve is fully open and the fluid can freely pass through.

When the plug is in the middle position, the valve is partially opened, and the fluid flow can be adjusted according to the opening of the plug.

The rotation of the plug-in board is controlled by a driving device, which can be manual, electric, or pneumatic.
