Conveniently-connected structure of highly-sealed liquid flow control ball valve

Abstract

The invention discloses a conveniently-connected structure of a highly-sealed liquid flow control ball valve. The conveniently-connected structure comprises a shell; a water passing groove is formed in the side wall of the shell, and a rotating groove is formed in the inner wall of the water passing groove; the inner wall of the rotating groove is slidably connected with a hollow ball, and circulating holes are formed in the inner walls of the two symmetrical ends of the ball correspondingly; and an air bag is glued to the inner wall of the upper side of the ball. The conveniently-connected structure has the advantages that through design of an air feeding rod and an air discharging rod, when the flow needs to be adjusted back again after excessive flow limiting, the air feeding rod and the air discharging rod can be simultaneously pressed, thus the air discharging rod drives a pushing block to extrude a connecting block, thus the connecting block drives an air discharging stop block to rotate, the inner wall environment of the air bag and the inner environment of an extrusion groove communicate, the air feeding rod drives an air feeding baffle to rotate, thus an air feeding groovecommunicates with the inner space of the extrusion groove, the air bag communicates with the outside environment, air in the air bag is released, thus the airbag is shrunk, the flow of a water flow is increased, and the flow of the water flow is adjusted.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a structure of a high-tight liquid flow control ball valve which is convenient for connection. Background technique [0002] The ball valve is an opening and closing part, which is driven by the valve stem and rotates around the ball valve axis; it can also be used for fluid adjustment and control, among which the hard-sealed V-shaped ball valve has a V-shaped ball core and a metal valve with surfacing welding carbide. There is a strong shear force between the seats, which is especially suitable for media containing fibers and tiny solid particles; while the multi-way ball valve can not only flexibly control the confluence, diversion and flow direction switching of media on the pipeline, but also can Close any channel and connect the other two channels; this type of valve should generally be installed horizontally in the pipeline; ball valves are divided into pneumatic ball v...
