Abstract
The utility model discloses a non-dead angle spherical valve, which comprises a valve cap, a valve rod, a valve body, a handle, a nut cap and a sphere. The valve cap and the valve body are connected through flanges fixedly connected through a plurality of screws; a sealing ring is additionally arranged on the connecting surface between the valve body and the valve cap; and the sealing of the sphere adopts the 100% spherical sealing structure. On one hand, the working pressure of a valve gate is improved, thereby achieving higher pressure resistance of the valve gate, and on the other hand, the easier disassembly of the valve gate realizes more convenient cleaning; the sealing ring is additionally arranged on the connecting surface between the valve body and the valve cap, thereby avoiding the leakage of the valve gate under high-pressure conditions; and the sealing of the sphere center is the 100% spherical sealing, thereby eliminating the clearance between the valve body and the sphere center and achieving the non-dead angle and non-detention effects.
Description
Technical field
The utility model relates to a kind of valve, specifically a kind of no dead angle ball valve.
Background technique
By being threaded, make valve pressure bad between the valve gap of the ball valve of prior art and the valve body, increase a little less than the crushing resistance that valve is not easy dismounting and makes cleaning; The situation of leaking outside occurs under the high-pressure situations, what original valve adopted is that the centre of sphere is partially sealed, has formed the space between the centre of sphere and valve body, has detention space, has brought inconvenience to cleaning.
The model utility content
(1) technical problem that will solve
Technical problem to be solved of the present utility model is the defective at prior art, no dead angle ball valve is provided, and no dead angle and zero is detained, and has strengthened the crushing resistance of valve, make the easier dismounting of valve make cleaning more convenient, the situation that leaks outside of having avoided valve under high-pressure situations, to occur.
(2) technological scheme
The technological scheme that its technical problem that solves the utility model adopts is: no dead angle ball valve, and its structure comprises valve gap, valve rod, valve body, handle, block, spheroid; The Placement of described valve gap and valve body adopts the many screws of flange to fixedly connected; On the junction surface of valve body, added seal ring with valve gap.
100% ball face sealing that described ball seal adopts.
(3) beneficial effect
No dead angle of the present utility model ball valve is compared with prior art, has following beneficial effect:
Valve body is whole to adopt the stainless steel forging to form, the profile of valve body and valve gap has adopted unique spherical design, the Placement of valve body and valve gap changes the present flange-type (four bar screw) in position by original being threaded, improved the valve working pressure on the one hand, strengthened the crushing resistance of valve, make the easier dismounting of valve make cleaning more convenient on the other hand, this is the function that original ball valve has not to be had (function capable of washing); On the junction surface of valve body, added seal ring, the situation that leaks outside of having avoided valve under high-pressure situations, to occur with valve gap; In the sealing of the centre of sphere: what original valve adopted is that the centre of sphere is partially sealed, has formed the space between the centre of sphere and valve body, has brought inconvenience to cleaning; 100% ball face sealing that existing centre of sphere sealing is adopted has been removed the gap between the valve body and the centre of sphere, thereby reaches no dead angle and do not have the effect of being detained.
Description of drawings
Figure is the structural representation of no dead angle of the present utility model ball valve.
Among the figure: 1. sealing gasket; 2. tetrafluoro; 3. valve body; 4. sealing gasket; 5. sealing gasket; 6. tight bushing; 7. handle; 8. block a shot; 9. valve rod; 10. screw; 11. spheroid.
Embodiment
Next explain below with reference to Figure of description no dead angle of the present utility model ball valve being done.
No dead angle of the present utility model ball valve, its structure comprise valve gap, valve rod 9, valve body 3, handle 7, block 8, spheroid 11; The Placement of described valve gap and valve body adopts the many screws 10 of flange to fixedly connected, and has improved the valve working pressure on the one hand, has strengthened the crushing resistance of valve, makes the easier dismounting of valve make cleaning more convenient on the other hand; On the junction surface of valve body, added seal ring, the situation that leaks outside of having avoided valve under high-pressure situations, to occur with valve gap.
100% ball face sealing that described spheroid 11 sealings are adopted.Removed the gap between valve body and the spheroid, thereby reached no dead angle and do not have the effect of being detained.
The above embodiment is a kind of of the more preferably concrete mode of execution of the utility model, and common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
Claims (2)
1, no dead angle ball valve, its structure comprises valve gap, valve rod, valve body, handle, block, spheroid; It is characterized in that: the Placement of described valve gap and valve body adopts the many screws of flange to fixedly connected; On the junction surface of valve body, added seal ring with valve gap.
2, no dead angle according to claim 1 ball valve is characterized in that: 100% ball face sealing that described ball seal adopts.
