Brief introduction of clip type insulation ball valve:

Referring to the characteristics of Italy products, compared with ordinary ball valves, this product has the advantages of short structural length, light weight, convenient installation and material saving. The insulation ball valve has good heat preservation effect. In addition, the valve seat adopts an elastic sealing structure, which is reliable and easy to open and close. It is equipped with fireproof structure. It can operate reliably and has good sealing property in case of fire. Antistatic structure can be installed according to user's requirement. A 90 degree switch with hole locating piece is set up, and the lock can be locked according to the requirement to prevent misoperation.

Two. The working principle of clip type insulation ball valve:

A metal jacket is welded between the two ends of the clamping heat preservation ball valve, and the connecting port of the jacket is arranged on the side and the bottom of the heat preservation ball valve, which is used for the inlet and outlet of the steam or the heat conducting oil, so as to achieve the heat preservation effect of the ball valve and ensure the normal circulation of the viscous medium. Because a jacket is added to the outside of the ball valve body. Mainly used in chemical, petroleum, pharmaceutical, metallurgical and other industries in the system pipeline, the main role is to transport in the normal temperature state will be solidified, easy crystallization of the medium.

Three, the characteristics of clip type insulation ball valve products:

1, the clip heat preservation ball valve adopts the integral jacket structure design, more uniform insulation, cold preservation.

2, the clip insulation ball valve is smaller than the general ball valve, lighter weight, and no leakage, good sealing performance.

3, jacket carbon steel pipe welding, more stable than the casting.

4, the diameter and diameter of the valve to one, medium flow in a straight line, small resistance, can effectively reduce the heat loss of medium in the pipeline.
