Description
Technical field
This utility model is related to ball valve technical field, specially a kind of cage labyrinth Filtering ball valve.
Background technology
Ball valve is driven by valve rod, and the valve rotating around ball valve axis.Also can be used for regulation and the control of fluid,
Wherein sealing has very strong shearing force between V-type ball valve its V-type core and metal seat valve of pile-up welding hard alloy firmly, especially suitable
Medium for fibre-bearing, small solid material etc..And multi-pass ball valve not only can flexibly control the interflow of medium on pipeline, divide
Stream and the switching of flow direction, also can close arbitrary passage simultaneously and so that two other passage is connected, ball valve is mainly used in pipeline
Make the flow direction cutting off, distribute and changing medium, it only needs to use the rotating torque of the operation ratating 90 degrees and very little with regard to energy
Close tight, ball valve has the advantages that wear-resisting, good seal performance, switch be light, long service life, filter ball of the prior art
Valve is although the effect of filtration can be played, but after life-time service, impurity particle causes to spheroid sealing surface of seat to wear and tear, shadow
Ring its service life.
Utility model content
The purpose of this utility model is to provide a kind of cage labyrinth Filtering ball valve, to solve to propose in above-mentioned background technology
Problem.
For achieving the above object, this utility model provides following technical scheme：A kind of cage labyrinth Filtering ball valve, including
Turbine-driven set and valve body, described valve body upper end is fixedly connected valve gap by lock screw, and described body base is provided with bolt,
Described turbine-driven set bottom is connected with valve gap top by seal assembly, and described seal assembly lower end is fixedly connected
Valve rod, described upper valve rod both sides fixedly mount key respectively, and described body cavity bottom is fixed with spheroid, and described spheroid connects outside
Lower valve rod, described lower valve rod bottom is screwed connection bottom end cover.
Preferably, also include cage labyrinth drainage screen, described cage labyrinth drainage screen uniformly have several filtering holes,
Described cage labyrinth drainage screen is fixedly mounted on body cavity side wall, and described cage labyrinth drainage screen upper end is provided with platen cover.
Preferably, described spheroid both sides are respectively fixed with valve seat, are provided with spring in described valve seat.
Preferably, described lower valve rod is fixedly connected body base by fixing bolt, described fixing bolt include stud and
Nut.
Preferably, described cage labyrinth drainage screen lower end is further fixed on impurity discharger.
Compared with prior art, the beneficial effects of the utility model are：
（1）This utility model structural principle is simple, and easy to use, easy maintenance and installation can effectively stop granule medium
The damage being mingled with to spheroid sealing surface of seat producing, extends the service life of ball valve.
（2）In this utility model, cage labyrinth drainage screen lower end is fixed with impurity discharger, does not need to remove during impurities removal
The bolt of body base only need to be opened, the granule foreign being deposited on bottom be gone out outside, improves by the attachment means of valve
Impurity expulsion efficiency.
（3）This utility model can effectively ensure that the good operation of granule medium in valve, has long service life, dimension
The low feature of shield expense.
