Description
Technical Field
The utility model relates to a ball valve technical field especially relates to a manual ball valve of three formula.
Background
The ball valve, the opening and closing piece (ball) is driven by the valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve body of the surfacing hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline. The ball valve is divided into a pneumatic ball valve, an electric ball valve and a manual ball valve according to the driving mode.
Although most of existing ball valves are provided with sliding limiting devices, the sliding limiting devices cannot be clamped on handles, and the ball valves easily slide down automatically under the self weight, so that the use is affected, and a three-piece manual ball valve is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the problems, a three-piece type manual ball valve is provided.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a three-piece type manual ball valve, includes the valve body, its characterized in that, two valve gaps are installed to valve body bilateral symmetry, the inside ball core that is provided with of valve body, the ball core upper end is equipped with the valve rod, peg graft in the ball core upper end after the valve rod lower extreme passes the valve body, the valve body both ends are equipped with the stopper, the inside gland that is provided with packing groove and cover on locating the valve rod of valve body, the packing inslot is filled with the filler with valve rod looks adaptation, handle nut and handle fixed link are passed through to the valve rod upper end, be equipped with the slip gag lever post on the handle.
As a further description of the above technical solution:
two valve seat sealing rings are symmetrically arranged between the inner wall of the valve body and the ball core.
As a further description of the above technical solution:
the handle is provided with a spring stop dog.
