Introduction To The Structure Of Thermal Insulation Ball Valve

3 Piece Threaded Ball Valve is a ball valve with an insulation layer covering the outer layer of the valve body. Its structure generally includes the following parts:

Valve body: usually adopts a ball valve structure, including valve body, valve seat, ball and other parts. The valve body is covered with an insulation layer, usually wrapped with insulation material.

Valve stem: connects the valve handle and the ball, and controls the flow of the medium by rotation.

Valve seat: The valve seat of the ball valve is usually a soft sealing structure to ensure the sealing performance of the valve.

Insulation layer: covered on the outside of the valve body, used to reduce the heat loss of the valve during operation and improve the insulation effect of the valve.

Valve seat seal: usually adopts packing or elastic seat ring and other structures to ensure the sealing performance of the valve.

The structure of the insulation ball valve is similar to that of the ordinary ball valve, but an insulation layer is added to the outside to improve the insulation effect of the valve, which is suitable for working conditions that require insulation function.
