Description
Technical field
The utility model belongs to technical field of valve manufacturing, relates to a kind of ball valve, particularly a kind of filtration Combined ball valve.
Background technique
Ball valve is that open-shut device (spheroid) is driven by valve rod; And the valve that rotates around the axis of valve rod; In the line transportation in industry, agricultural, fields such as the energy and daily life, be widely used, be used for controlling plumbing fixtures medium connection or block the flow with the pipeline medium, yet the medium in the line transportation often exists various impurity; These impurity not only have influence on the purity of medium, and easily the equipment such as ball valve in the line transportation are caused damage.
To the problem that exists; For the equipment such as ball valve in the better protection pipeline transport; People have made various designs and improvement to the filtration that is used for filter medium impurity in the line transportation; Some has also applied for patent, and for example the Chinese patent documents and materials disclose the track ball valve [application number: 201020648432.0 that is provided with filter screen in the spool; Notice of authorization number: CN201916522U], it comprises valve body, valve rod, spool, flap, it is characterized in that, is provided with filter screen in the described spool.
This ball valve is provided with filter screen in spool, the pipeline medium is when flowing through this ball valve, and the filter screen in the spool can fall the contaminant filter in the medium, plays the effect of protection ball valve; But the filter screen of installing in this ball valve core is difficult to from valve body, take out, in use for some time; Accumulate abundant impurity on the filter screen, can be bonded on the filter screen, stopped up filter screen; Cause medium when this ball valve, the difficulty of change even can't pass through this ball valve causes the obstruction of pipeline; And, directly cause scrapping of ball valve because very trouble can't replaced and clean to the filter screen in the spool, working life is short.
Summary of the invention
The purpose of the utility model is to the problems referred to above that exist in the existing technology, provides a kind of and has had filtering function and Combined ball valve is filtered in cleaning easily.
The purpose of the utility model can realize through following technical proposal: a kind of filtration Combined ball valve; Comprise valve body, valve rod and spherical valve core with flow channels; Described spool is positioned at valve body, and the inner and the spool of described valve rod are connected, and the outer end of valve rod is stretched out valve body and is used to connect handle; It is characterized in that; Described valve body sidepiece has the mount inlet with the coaxial setting of valve rod, and described spool has perpendicular to flow channels and the through hole that is communicated with fitting seat, and the tubular filter screen that passes mount inlet and through hole is housed in the described spool; Described filter screen sidepiece has towards the opening of valve inleting water end and filter screen and mount inlet place and is provided with the position structure with the filter screen location, and described mount inlet is fixed with the sealing blanking cover.
This filtration Combined ball valve in use owing to the effect of position structure, makes filter screen can not change with the valve core rotation occurrence positions, and the opening direction of filter screen guarantees to filter and can effectively carry out all the time towards the valve inleting water end.
When this filtration Combined ball valve uses; Pass through rotation valve rod; Drive valve core rotation flow channels all is communicated with feed-water end and the waterexit end of valve body, medium is from the feed-water end inflow flow channels of valve body at this moment, and medium is from the opening filter screen of flowing through afterwards; Filter screen is with the contaminant filter in the medium, and the medium after the filtration flows out from the waterexit end of valve body.Because impurity can accumulate in filter screen, so need clear up filter screen after using a period of time, close spool through valve rod this moment; Take off the sealing blanking cover, just can filter screen be taken out from mount inlet, outwell the impurity in the filter screen; Use the flushing with clean water filter screen in case of necessity; The filter screen cleaning is convenient, and the filter screen after will clearing up afterwards reloads in the mount inlet, refills the sealing blanking cover mount inlet is sealed.
In above-mentioned filtration Combined ball valve; Described position structure comprises that filter screen is positioned at the plastic layer that is round one that the end at mount inlet place is fixed with; Described plastic layer one radially has several convexities, and described mount inlet end has the groove that supplies protruding embedding.After filter screen is installed; The convexity of plastic layer one all is embedded in the corresponding groove, and filter screen can not rotate like this, has realized the circumferential location of filter screen; Because the sealing blanking cover seals mount inlet; So the sealing blanking cover contacts at the end that filter screen is positioned at the mount inlet place, makes filter screen not move axially, and has realized the axially locating of filter screen.Position structure guarantees that filter screen in use can not change the position, guarantees that filter process carries out smoothly.
In above-mentioned filtration Combined ball valve, the end that described filter screen is positioned at spool is fixed with plastic layer two, and described plastic layer two coats this end formation of filter screen and seals.Plastic layer two can prevent that impurity from spilling from this end of filter screen, guarantees the valve core inside cleaning.
In above-mentioned filtration Combined ball valve, the peristome portion of described filter screen is coated with plastic layer three.Plastic layer three makes peristome portion to fit in spool preferably, and in use, the setting of plastic layer three also makes opening can bear big medium impulse force and deformation can not take place, has long working life.
In above-mentioned filtration Combined ball valve; Described valve body has the water inlet that is connected with feed-water end and is in charge of; Into water spool is housed in described water inlet is in charge of, and the water inlet spool is fixed with into the inner of water valve rod, and the outer end of water inlet valve rod is stretched out into water and is in charge of and is used to connect water inletshank.What the spool and the spool of intaking were in charge of, intakes in water inlet is arranged so that this filtration Combined ball valve selectivity when pipeline is connected is stronger, and using scope is wider.
In above-mentioned filtration Combined ball valve; Described valve body has the water outlet that is connected with the waterexit end and is in charge of; The water outlet spool is housed in described water outlet is in charge of, and the water outlet spool is fixed with the inner of water outlet valve rod, and the outer end of water outlet valve rod is stretched out water outlet and is in charge of and is used to connect the water outlet handle.Water outlet is in charge of, water outlet spool and water outlet spool be arranged so that this filtration Combined ball valve selectivity when pipeline is connected is stronger, using scope is wider.
In above-mentioned filtration Combined ball valve, the outside of described mount inlet is arranged with the seal ring between mount inlet and sealing blanking cover.Seal ring has guaranteed the sealing at sealing blanking cover place, prevents the medium seepage.
Compared with prior art, the filtration Combined ball valve that provides of the utility model has the following advantages:
1, this filtration Combined ball valve in use can filter medium; And impurity concentrated in the filter screen; After using a period of time filter screen is taken out from mount inlet, the impurity in the cleaning filter screen is reinstalled filter screen again; Scale removal process is convenient, has prolonged the working life of this filtration Combined ball valve like this.
2, this filtration Combined ball valve through be provided with the water inlet be in charge of, intake spool, water outlet is in charge of and the setting of water outlet spool, makes that this filtration Combined ball valve selectivity when pipeline connects is stronger, using scope is wider.
