Abstract

The invention relates to an alternation ball check valve which comprises a valve body, a sphere valve core, a valve seat, a sphere valve core operating part and a valve seat limiting device. A liquid outlet is circular, the rotating axis of the sphere valve core penetrates through the circle center of the liquid outlet, a second liquid inlet communicated with a through cavity is formed on the valve body, a first liquid inlet and the second liquid inlet are symmetrically formed at two sides of the liquid outlet, and when the sphere valve core is rotated by corresponding angles clockwise or counterclockwise, the first liquid inlet is communicated with the liquid outlet or the second liquid inlet is communicated with the liquid outlet by a channel which is 7-shaped. A valve clack is obliquely hinged on the inner wall of the upper end of the turning part of the 7-shaped channel, and an inclined footstep surface is formed on the inner wall of the lower end of the turning part of the channel, so that under the gravity of the valve clack, the valve clack abuts against the inclined footstep surface tightly to cut off the channel in one direction. The chip type internal-thread ball valve can be used in the occasions needing to alternately control the cut-off or the opening of the two liquid inlets.

Description

A kind of alternately ball check valve
Technical field
The present invention relates to a kind of ball valve, specifically, is a kind of alternately ball check valve.
Background technique
The faucet body of ball valve is a spheroid, and the axis of spheroid is provided with manhole or passage.Ball valve mainly is used for making cut-out, distributes and change the flow direction of medium in pipeline, and it only needs to use very little moment of rotation just can close tight to pipeline to the operation that spheroid is rotated 90 degree.The ball valve optimum is made switch, cut-off valve uses.Chinese patent document CN2349411Y has proposed a kind of single piece type internal thread ball valve.This single piece type internal thread ball valve still have tapped valve body, valve seat, spheroid spool, with the valve rod and the handle thereof of spheroid spool interlock, valve rod mounting hole place, valve body middle part is the boss shape, valve rod is installed hole wall and is set up O type circle.Existing technology increases axial thickness and sets up the O RunddichtringO and can reach desirable sealing effect between this valve seal key position valve rod and valve body; But this existing technology can only be used on the pipeline with a liquid entering hole and a liquid outlet; Pipeline is blocked or opens; And have two liquid entering holes and a liquid outlet, and need alternately control the occasion that the non-return of this two liquid entering hole blocks or opens, but can not use.
Summary of the invention
For this reason; Technical problem to be solved by this invention is that internal thread ball valve of the prior art can only be used to have the pipeline of a liquid entering hole and a liquid outlet; To the problem that pipeline blocks or opens, provide a kind of and can alternately control blocking or alternately ball check valve that non-return is opened of two liquid entering holes.
For solving the problems of the technologies described above, a kind of alternately ball check valve of the present invention comprises
