Description

Technical Field

[0001] The utility model relates to a heavy-duty ball valve pump with convenient installation, belonging to the field of ball valve pumps. Background Technique

[0002] The opening and closing part (sphere) of a ball valve pump is a valve that is driven by a motor to drive a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, 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 classified according to the driving method into: pneumatic ball valves, electric ball valves, and manual ball valves.

[0003] In the prior art, when installing the position of the ball valve, bolts are needed for fixation. However, due to the firm installation of the valve seat and the valve body, multiple groups of screw holes need to be set, and then the bolts are inserted for fixation. However, there are too many screw holes in the upper and lower positions, resulting in troublesome docking of the screw holes during the upper and lower docking installation process, and the screw holes are prone to misalignment during the upper and lower docking process. Therefore, it is necessary to design a heavy-duty ball valve pump with convenient and quick positioning of screw holes and convenient installation. Content of the Utility Model

The outer wall of the positioning block is provided with positioning beads, and a ball bearing is rotatably installed on the top of the positioning block.

[0009] Further, four groups of the positioning assemblies are provided, and the included angle between each group is 90°. A chute is opened at the bottom of the mounting seat, and the ball bearings slide along the chute.

[0024] The above structure filters the liquid passing through the inside of the valve body 6 through the filter screen 11.

[0025] Preferably, the mounting base 1 and the connecting seat 4 are mutually docked, and the mounting base 1 and the connecting seat 4 are connected by bolts in a threaded manner, and the valve seat 10 and the valve cover 12 are connected to each other by bolts.

[0026] The above structure is fixedly installed after positioning by bolts.
