Description
Technical field
This utility model belongs to valve field, is specifically related to a kind of ball valve.
Background technology
At present, increasing ball valve starts to arrange filtration in valve body, but great majority are the directions being directly perpendicular to fluid flowing at the inlet in valve body or liquid outlet is provided with drainage screen.Although it can filter the impurity in the fluid flowing through valve, but after using a period of time, the impurity piled up on drainage screen can affect the flow velocity of fluid, even block runner, and this design being built in valve body makes drainage screen be not easy to be replaced, and want to change filter screen, then need from pipeline, unload whole valve down, and valve body is taken apart, just can be taken out drainage screen and be carried out.
Utility model content
For overcoming the above-mentioned problems in the prior art, this utility model provides the ball valve of a kind of filtration with convenient dismounting, only can need to be pulled down from pipeline by filtration, eject or release drainage screen and be carried out in the case of not tearing valve open.
This utility model is concrete by the following technical solutions:
A kind of ball valve, it is characterised in that including main valve and interior coil, wherein, described main valve includes valve body, core, valve rod, spanner；There are inlet, liquid outlet and admission chamber in described valve body, go out sap cavity, described core is positioned at described valve body, in the lower end of described valve rod penetrates described valve body and being connected with the top of described core, one end of described spanner is provided with perforate, and the upper end of described valve rod is inserted in described perforate；Described inlet, liquid outlet are provided with female thread structure；
Being provided with embedded filter screen in the body of described interior coil, described interior coil is external thread structure, and one section of body of described interior coil screws in described inlet；Threadeding with feed tube in one end away from described inlet on described interior coil, described liquid outlet is threadeded with drain pipe, and one end of described admission chamber is provided with intake screen, described in go out one end of sap cavity and be provided with outlet filter screen.
Preferably, described embedded filter screen is at least one.
This utility model compared with prior art has the advantages that
1. external by filtration, the main valve split with ball valve is used to arrange, will be embedded in interior coil by drainage screen, interior coil is connected with main valve inlet threaded one end, when the cleaned filter screen of needs, only embedded filter screen need to be pulled down, just can take out drainage screen to be carried out, pull down without by whole valve, greatly facilitate the cleaning to filtration, and then reduce the maintenance cost of whole tubing.
2. on the basis of interior coil is embedded with drainage screen, liquid inlet and outlet intracavity in valve body assists further and arranges two filter screens, improve filter effect further, and owing to there being the preferential filtration of embedded filter screen, two filter screen life-time service of liquid inlet and outlet intracavity also will not pile up impurity to the degree affecting fluid circulation.

Fig. 2 is the schematic front view of coil in the ball valve in this utility model one embodiment.
Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described in further details.
As shown in Figure 1-2, in a specific embodiment, a kind of ball valve, it includes main valve and interior coil 8, and wherein, main valve includes valve body 1, core 2, valve rod 3, spanner 7；Having inlet 4, liquid outlet 5 and admission chamber in valve body 1, go out sap cavity, core 2 is positioned at valve body 1, in the lower end of valve rod 3 penetrates valve body 1 and is connected with the top of core 2, and one end of spanner 7 is provided with perforate, and the upper end of valve rod 3 is inserted in perforate；Inlet, liquid outlet are provided with female thread structure；Being provided with embedded filter screen 9 in the body of interior coil 8, interior coil 8 is external thread structure, and one section of body of interior coil 8 screws in inlet 4.Preferably, the number of embedded filter screen 9 is at least one, for ensure filter effect, can in interior coil 8 body, be perpendicular to fluid flowing direction on be set up in parallel multiple, embedded filter screen 9 can be pushed into or head in the body of interior coil 8, is stuck on the inwall of interior coil 8.In can also be preferential, the body at interior coil 8 can arrange female thread, so that embedded filter screen 9 screws in the body of interior coil 8.
Preferably, the one end away from inlet 4 on interior coil 8, i.e. relative to being connected the other end of end with valve body 1, to threaded with feed tube, liquid outlet 5 is threadeded with drain pipe.Preferably, for improving filter effect further, one end of admission chamber is provided with intake screen 6, and the one end going out sap cavity is provided with outlet filter screen.And owing to there being the preferential filtration of embedded filter screen, even if intake screen, outlet filter screen life-time service also will not pile up impurity to affect the degree that fluid circulates, therefore, typically need not to embedded filter screen to be the most relatively frequently removed cleaning.
Specific works principle is: the interior coil one end being built-in with drainage screen is connected with the inlet of ball valve, the other end is connected with feed tube, when liquid flows through interior coil and is also introduced into the valve body of ball valve, major part impurity has been filtered out, and when needing to clean filter screen, only pull down interior coil and be carried out.
This utility model applicant combines Figure of description and describes embodiment of the present utility model in detail and describe, but those skilled in the art should understand that, above example is only a kind of embodiment of the present utility model, it is merely to illustrate this utility model, the structure of the most each parts, connected modes etc. all can change, detailed explanation is intended merely to help reader to be more fully understood that this utility model spirit, and not restriction to this utility model protection domain, on the contrary, any any improvement modification made based on spirit of the present utility model and equivalents and improvement the most should not got rid of outside protection domain of the present utility model.
