Product Application:

Tank bottom valve is suitable for the pipeline and the warehouse of the mud circulation tank with mud as the medium. As the control valve for suction and discharge, it also acts as the switch for the balance control between the warehouses.The valve is compact in structure and reasonable is design. Years of experience, the use of verne seals, longer life, more stable performance.

Structural Principle:

The novel subsea valve (underflow valve) comprises an outer tube, a connecting rod, a connecting tube and a screw rod. The lower end side of the outer tube is connected with the connecting tube, the connecting rod is arranged in the outer tube, the lead rod is connected with the connecting rod in the outer tube, the connecting rod and the setting The sealing rubber is connected at the bottom end of the outer tube, and the sealing rubber is sealed and fitted with the valve base. The valve base is a cone structure with a bevel on the inner side, and the surface of the sealing rubber contacting the valve base is the same inclined surface as the slope of the valve base, and the sealing rubber passes. The upper and lower circular metal plates are fixed; the connection portion between the outer tube and the outer screw barrel is above the tank surface. The utility model improves the sealing performance of the subsea valve itself, and the cone sealing structure reduces the axial bearing capacity of the lifting screw to the sealing rubber by about *0%, thereby prolonging the service life of the rubber, and the connecting portion of the outer tube and the outer cylinder of the screw Raised above the tank surface to meet the requirements for rapid maintenance.
