The circulation or cut-off of interior medium；When flow of media, ball valve is in the open state；When the maximum flow of flow of media, at ball valve
In fully open state；When medium cut-off circulation, ball valve is in off state.
In long-term use, since the liquid in pipeline all has impurity, impurity is easy accumulation and causes pipeline and go out pipeline
The blocking at the mouth of a river influences the normal use of pipeline, and in order to solve this problem, people are mounted with for impurity screening in ball valve
Filter screen need to tighten together with ball valve during installation, cause filter screen although filter screen has good filtration
Disassembly is not easy, or even damages ball valve in disassembly, because other factors influence, be may cause the reflux of impurity, is made the direct heap of impurity
Product causes the blocking of pipeline in pipeline, while when ball valve is rotated to clean-up port, the impurity reflux in possible ball valve is to cleaning
Mouth results in blockage, and causes the damage of clean-up port.
Summary of the invention
The purpose of this utility model is to provide a kind of impurity screening and anti-for the above-mentioned problems in the prior art
The ball valve of backflow.
The purpose of this utility model can be realized by the following technical scheme: a kind of Filtering ball valve, including valve body, core,
Valve rod, filter screen and swivel head, the valve body include interconnected water outlet, valve chamber, water inlet and clean-up port, described
Ball valve is installed in the valve chamber in the valve body, and it is logical that the connection for making water outlet be connected with water inlet is provided in the core
Road, which is characterized in that the filter screen is installed in the communicating passage in the core, which is basket with netting on top structure,
And be recessed inwardly in the middle part of the filter screen lateral wall and to form the recessed portion with radian, the filter screen is located at opening in filter screen
It is provided with the convex ring that filter screen position is fixedly connected with and limited with filter screen on periphery wall at mouthful, the connection in the core is logical
Road is located at the annular groove opened up at convex ring convenient for convex ring insertion, be provided in the annular groove for fix convex ring and
Dismountable circlip, when ball valve, which is in, closes, the communicating passage in core is connected with clean-up port.
In a kind of above-mentioned Filtering ball valve, it is also equipped in the valve body for reinforcing valve inner leakproofness
Sealing ring and lower seal, and upper seal and lower seal are located at the upper and lower ends of core.
In a kind of above-mentioned Filtering ball valve, the communicating passage in the core, which is additionally provided with, prevents convex ring retrogressing de-
Stop collar from annular groove, and stop collar is integrated with communicating passage and is arranged.
In a kind of above-mentioned Filtering ball valve, the filter screen, which is located to be provided on the inner sidewall of recessed portion, to be obliquely installed
Anti- stream ring, and anti-stream ring is integrated with filter screen and is arranged.
Compared with prior art, the recessed portion that this Filtering ball valve is recessed inwardly in the middle part of filter screen lateral wall, filter screen
Periphery wall on be provided with convex ring, the communicating passage in core be located at opened up at convex ring convenient for convex ring insertion annular
Slot is provided with dismountable circlip in annular groove.Filter screen is limited in company by dismountable circlip by the setting of above structure
On annular groove in circulation passage, filter screen is enable to disassemble in core, simultaneously because the shape that is recessed inwardly in the middle part of filter screen
At recessed portion, enter impurity after filter screen by liquid and be not likely to produce reflux, prevents impurity from accumulating and damaging clear in pipeline
Manage mouth.
