Abstract
The utility model provides a valve, including valve body, valve gap, valve rod, rotating switch, the valve clack, the valve rod passes the valve gap stretches into in the inner chamber of valve body, the valve rod with the valve clack rigid coupling, its characterized in that: the valve clack is become with the circulation body group by mutually perpendicular's obturator, the circulation body is equipped with the through -hole, the valve gap top is equipped with the annular groove, be equipped with relative stopper in the recess, on the valve rod with the groove phase is to locating to be equipped with the fixed block. The utility model discloses simple structure, rotating switch drive the valve clack and do 90 rotations to control valve opens with closed, is equipped with the through -hole in certain aperture on the circulation body simultaneously, thereby reduces the velocity of flow of medium, reduces the too big potential safety hazard that causes of primary pressure.
Description
Technical field
The utility model is specifically related to a kind of valve.
Background technique
Valve is the controlling component in fluid delivery system, valve is when convection cell controls, mainly by flap being contacted with the valve seat in sealing mechanism and being separated the effect reaching opening/shutting valve, but because the area of contact of flap and valve seat is little, or valve stem tip is fixed insecure, under liquid strong pressure constantly impacts, flap is caused to play pendulum, affect the sealing of valve, a lot of businessman adds sealing gasket or block to limit rocking of valve rod in the junction of valve gap and valve body, its complex structure, also very high to the requirement of sealing material, cost is corresponding increase also.
Model utility content
For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of valve, comprise valve body, valve gap, valve rod, rotating switch, flap, described valve rod stretches in the inner chamber of described valve body through described valve gap, described valve rod and described flap affixed, described flap is made up of orthogonal closure and flow body, described flow body is provided with through hole, described valve gap top is provided with annular groove, is provided with relative limiting stopper in described groove, and described valve rod is provided with fixed block with described groove opposite position.
Further, the diameter of described closure and described flow body equals the diameter of described circulation duct.
Further, the thickness of described closure and described flow body equals described valve aperture.
Further, described limiting stopper is provided with 4 along described groove, and in 90 ° between limiting stopper.
Further, the fixed block on described valve rod, between limiting stopper, rotates between two limiting stoppers.
Further, between described rotating switch and valve gap, be provided with nut, described valve rod is provided with the thread section matched.
Further, described nut is fixed on described valve gap by stiffening rib.
The advantage that the utility model has and beneficial effect are:
1, the utility model adopts mutually perpendicular closure and flow body composition flap, and the diameter of closure and flow body and thickness all accurately arrange and fits tightly with valve interior wall, thus improve the sealing of valve;
2, valve gap arranges limiting stopper, make valve rod drive the scope of flap within 90 ° to rotate, avoid flap to rotate constantly under the impact of liquid, and valve stem tip is provided with thread section, screw with nut and connect, by strengthening the swing that fixedly further avoid flap to valve rod.
3, flow body is provided with through hole, thus reduces the flow velocity of liquid, serves buffer function, causes liquid brute force to spray cause danger when preventing from opening valve because liquid pressure is excessive.

In figure: 1. valve body, 2. valve gap, 3. valve rod, 4. rotating switch, 5. nut, 6. stiffening rib, 7. closure, 8. flow body, 9. through hole, 10. groove, 11. limiting stoppers, 12. fixed blocks.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of valve, comprise valve body 1, valve gap 2, valve rod 3, rotating switch 4, flap, described valve rod 3 stretches in the inner chamber of described valve body 1 through described valve gap 2, and described valve rod 3 is affixed with described flap, it is characterized in that: described flap is made up of orthogonal closure 7 and flow body 8, described flow body 8 is provided with through hole 7, thus reduce the flow velocity of liquid, serve buffer function, cause because liquid pressure is excessive liquid brute force to spray when preventing from opening valve and cause danger; Described valve gap 2 top is provided with annular groove 10, is provided with relative limiting stopper 11 in described groove 10, and described valve rod 3 is provided with fixed block 12 with described groove 10 opposite position.
In order to fit tightly with strengthening flap and valve body 1 inwall, further, the diameter of described closure 7 and described flow body 8 equals the diameter of described circulation duct; The thickness of described closure 7 and described flow body 8 equals described valve aperture.
In order to prevent flap from rotating constantly under the impact of liquid, as shown in Figure 4, described limiting stopper 11 is provided with 4 along described groove 10, and in 90 ° between limiting stopper 11; Fixed block 12 on described valve rod 3, between limiting stopper 11, rotates between two limiting stoppers 11.
In order to strengthen the steadiness of valve rod 3 thus prevent the swing of flap further, further, between described rotating switch 4 and valve gap 2, be provided with nut 5, described nut 5 is fixed on described valve gap 2 by stiffening rib 6, and described valve rod 3 is provided with the thread section matched.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
