Structural characteristics of orbital ball valves

Release time:

2024-04-26

Structural characteristics: The ball valve has the advantages of small size, compact structure, convenient use and installation, and long life. With no friction sealing structure design, the valve is opened when the ball rotates before leaving the sealing surface after rotation, the contact between the sealing surface without scraping effect, prolong the use of the valve. When the valve is closed, the mechanical wedge extrusion seal is applied downward by the valve stem to obtain a tight sealing effect. With the change of medium temperature, the stress of the pipeline will not affect the mechanical properties and sealing performance of the valve. When the valve is closed, the ball in the rotation process, the ball and the valve seat to maintain a certain space, due to the rotation of the ball flow will be reduced, the flow rate increases so as to achieve the role of flushing the sealing surface, so that it remains clean.

Spare thrust bearing, the ball rotates 90 degrees torque is small.
