Abstract
A non-return ball valve comprises a valve cover, a valve body, a ball body, valve bases, a baffle and a valve rod, wherein the valve body is connected to the valve cover by threads, the ball body is disposed inside the valve body, the valve bases are disposed between the ball body and the valve body and the valve cover, and the baffle is disposed inside a ball body pipeline and firmly connected inside the ball body pipeline by bolts; the valve rod is disposed inside the valve body, the tail end of the valve rod is connected to the ball body, the top end is connected to a handle, and the ball body can be rotated by driving rotation of the handle in order to control opening or closing of the ball valve; and a medium inlet is disposed inside the valve cover and a medium outlet is disposed at the tail end of the valve body. When the handle is rotated, the ball valve is opened, a medium flows from the medium inlet. When flowing through the ball body, the medium applies impulsion to open the baffle and flows out from the medium outlet; when being broken off, the medium flows back, so that the baffle is closed to stop the regurgitant medium and the ball valve can be closed by rotating the handle. The non-return ball valve in the utility model has the advantages that the non-return ball valve can prevent backflow, protects the pipeline, and has long service life and simple structure.
Description
Technical field
The utility model relates to ball valve, is specifically related to a kind of band check function ball valve.
Background technique
Ball valve is a kind of common valve, is realized and being opened or the medium channel of closing by rotatable handle, on pipeline, mainly play a part to cut off, shunting and change MEDIA FLOW to, simple in structure; Ball valve is widely used in water supply line, in the time cutting off the water suddenly, and ducted medium back flow, the pressure that medium back flow produces easily causes pipeline damage.
Model utility content
The purpose of this utility model is to provide a kind of band check function ball valve, the utlity model has anti-backflow, protection pipeline, and long service life, simple in structure.
The technological scheme that the utility model relates to:
A kind of band check function ball valve, is made up of valve gap, valve body, spheroid, valve seat, baffle plate and valve rod.
Described valve body and valve gap are threaded connection, and are mounted with a spheroid in valve body, between spheroid and valve body, valve gap, are provided with valve seat, in described spheroid pipeline, are mounted with a baffle plate, are bolted to connection in spheroid pipeline.
In described valve body, be mounted with a valve rod, valve stem end is connected with spheroid, and top is connected with handle, and driving handle rotation can make spheroid rotation, opens or closes thereby control ball valve.
In valve gap, have a medium import, valve body end has a media outlet.Work as rotatable handle, ball valve is opened, and medium flows into from medium import, and while flowing through spheroid, the impulse force of medium is opened baffle plate, and medium flows out from media outlet; And after medium is interrupted, medium back flow, flapper closure is by the medium cut-off refluxing, and then rotatable handgrip is closed ball valve.
Advantage of the present utility model, anti-backflow, protection pipeline, long service life, simple in structure.
Brief description of the drawings
Fig. 1 is complete section structural representation of the present utility model.
Fig. 2 is A-A cross-sectional view of the present utility model.
Wherein: 1. valve gap, 11. medium imports, 2. valve body, 21. media outlets, 3. spheroid, 4. valve seat, 5. baffle plate, 6. valve rod, 7. hexagon nut, 8. butterfly spring, 9. retaining cap, 10. trim ring, 13. fillers, 14.O type circle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of band check function ball valve, is made up of valve gap 1, valve body 2, spheroid 3, valve seat 4, baffle plate 5 and valve 6 bars the utility model.
Described valve body 2 is threaded connection with valve gap 1, is mounted with a spheroid 3 in valve body 2, between spheroid 3 and valve body 2, valve gap 1, is provided with valve seat 4, in described spheroid 3 pipelines, is mounted with a baffle plate 5, is bolted to connection in spheroid 3 pipelines.
In described valve body 2, be mounted with a valve rod 6, valve rod 6 ends are connected with spheroid 3, and top is connected with handle, and driving handle rotation can make spheroid 3 rotate, and open or close thereby control ball valve 3.
In valve gap 1, have a medium import 11, valve body 2 ends have a media outlet 21.Work as rotatable handle, ball valve 3 is opened, and medium flows into from medium import 11, and while flowing through spheroid 3, the impulse force of medium is opened baffle plate 5, and medium flows out from media outlet 21; And after medium is interrupted, medium back flow, baffle plate 5 is closed the medium cut-off refluxing, and then rotatable handgrip is closed ball valve 3.
