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 present invention relates to the technical field of ball valves, in particular to a structure of a high-sealing liquid flow control ball valve that is convenient for connection. Background technique

[0002] A ball valve is an opening and closing part, a valve that is driven by the valve stem and rotates around the axis of the ball valve; it can also be used for fluid adjustment and control. Among them, the hard-sealed V-shaped ball valve has a V-shaped ball core and a metal valve made of surfacing hard alloy. There is a strong shear force between the seats, which is especially suitable for media containing fibers, small solid particles, etc.; and the multi-way ball valve in the pipeline can not only flexibly control the confluence, divergence, and flow direction switching of the media, but also Close any channel to connect the other two channels; this type of valve should generally be installed horizontally in the pipeline; ball valves are divided into...

Embodiment

[0023] Reference Figure 1-4 , An easy-to-connect structure of a high-sealing liquid flow control ball valve, including a housing 1, a water channel 2 is provided on the side wall of the housing 1, a rotating groove 3 is provided on the inner wall of the water channel 2, and the inner wall of the rotating groove 3 is slidingly connected with a hollow The inner wall of the symmetrical two ends of the sphere 4 is provided with a circulation hole 5, the upper inner wall of the sphere 4 is glued with an airbag 6, and the upper end side wall of the sphere 4 is penetrated with a vent groove 7, which communicates with the interior of the airbag 6. The upper end of the sphere 4 is welded with a rotating shaft 10, and the upper end of the shell 1 is welded with a rotating shell 14. The rotating shaft 10 penetrates the upper wall of the shell 1 and the rotatable shell 14 and extends to the upper end of the rotating shell 14. The inside of the rotating shaft 10 is provided with a limited f...
