Subsea Valve

HDF subsea valve (underflow valve) is suitable for the pipeline and warehouse of the mud circulation tank with mud as the medium, as a control valve for suction and discharge, and also acts as a switch for balance control between warehouses. This valve has a compact structure, reasonable design, gathers many years of experience, and uses a valve seal, which has a longer service life and more stable performance.

The HDF subsea valve (underflow valve) includes an outer pipe, a connecting rod, a connecting pipe, and a screw. The lower end of the outer pipe is connected to the connecting pipe. The connecting rod is arranged in the outer pipe. The screw is connected to the connecting rod in the outer pipe, and the connecting rod is connected to the connecting rod. The seal rubber at the inner bottom end of the outer tube is connected, and the seal rubber is sealed and fitted with the valve base. The valve base is a cone structure with an inclined surface on the inside. The surface of the seal rubber and the valve base is the same inclined surface as the inclined surface of the valve base, and the seal rubber passes The upper and lower two circular metal plates are fixed; the connection part of the outer tube and the outer cylinder of the screw is above the surface of the tank.

The utility model improves the sealing performance of the submarine valve itself, and the conical surface sealing structure reduces the axial bearing capacity of the lifting screw to the sealing rubber by about 20%, thereby prolonging the service life of the rubber, and the connecting part of the outer tube and the outer cylinder of the screw It is raised above the tank surface to meet the requirements of quick maintenance.
