Abstract
The utility model relates to a full-bore rubber-sealed eccentric full ball valve. The full-bore rubber-sealed eccentric full ball valve comprises a self-lubricating bearing, an O-ring, a packing gland, a back end cover, anti-attrition pads, a valve seat on a valve body and an adjusting press plate on a ball body; the whole full-bore rubber-sealed eccentric full ball valve adopts a double-eccentric and full-bore straight-through-type runner structure; the self-lubricating bearing is adopted on a shaft sleeve and directly installed inside a shaft hole of the valve body, the O-ring is used for dust prevention at a bearing in and out place, and the anti-attrition pads are added to the packing gland and an inner hole of the back end cover; and both the valve seat on the valve body and the adjusting press plate on the ball body adopt split structures and are fixed through screws. The full-bore rubber-sealed eccentric full ball valve has the benefits as follows: the friction moment at a shafting part is reduced greatly, the problem of the overlarge opening torque is solved effectively, and the full ball valve is long in service life, convenient to operate and capable of saving energy and reducing emission.
Description
Technical field
The utility model relates to valve field, relates in particular to the eccentric all-ball valve of a kind of full-bore rubber seal.
Background technique
Ball valve is used in various pipe-line systems widely now, not only require to carry out on-line maintenance, and operational torque is excessive.In addition country calls energy-saving and emission-reduction energetically, and this kind of eccentric all-ball valve of new structure full-bore rubber seal arises at the historic moment.
Model utility content
Technical problem to be solved in the utility model is the above-mentioned defect that overcomes ball valve in prior art, provides a kind of full-bore rubber seal eccentric all-ball valve.
The utility model solves the technological scheme that its technical problem adopts:
The eccentric all-ball valve of full-bore rubber seal, is characterized in that, comprises valve seat on self oiling bearing, O type circle, Gland, rear end cover, anti-wear gasket, valve body and the adjusting pressing plate on spheroid; The whole flow passage structure that adopts two bias and full-bore straight-through type of the eccentric all-ball valve of described full-bore rubber seal; Axle sleeve adopts self oiling bearing, and it is inner that self oiling bearing is directly installed on valve body axis hole, and bearing turnover place is dustproof by O type circle, and Gland and rear end cover endoporus place increase anti-wear gasket; Valve seat on valve body and the adjusting pressing plate on spheroid all adopt Split type structure, and the valve seat on valve body and the adjusting pressing plate on spheroid are all fixed by screw.
The beneficial effects of the utility model are: the self oiling bearing that is by axle, it is light that the anti-wear gasket at Gland, rear end cover place is realized unlatching, and the valve seat on valve body and the adjusting pressing plate on spheroid all adopt Split type structure, for big-diameter ball valve, make on-line control or change convenient and safety.Adopt two eccentric structures, during unlatching, rubber seal hightails sealing surface, wear and tear little, and long service life.The design of full-bore straight-through type flow passage makes this valve flow resistance little, has reached good energy-saving effect.Greatly reduce axle pastern position friction torque, effectively solved and opened the excessive problem of moment of torsion, and long service life, operate light, energy-saving and emission-reduction.

Fig. 3 is valve seat on valve body and the adjusting pressing plate position enlarged view on spheroid.
Fig. 4 is eccentric structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the eccentric all-ball valve of a kind of full-bore rubber seal, comprises valve seat on self oiling bearing, O type circle, Gland, rear end cover, anti-wear gasket, valve body and the adjusting pressing plate on spheroid; The whole flow passage structure that adopts two bias and full-bore straight-through type of the eccentric all-ball valve of described full-bore rubber seal.The whole pair eccentric structures that adopt of the eccentric all-ball valve of described full-bore rubber seal, during unlatching, rubber seal hightails sealing surface, weares and teares little, greatly increases the working life of rubber seal; Adopt full-bore straight-through type flow passage structure, make this valve flow resistance little, reached good energy-saving effect.
As shown in Fig. 2 a, 2b, axle sleeve adopts self oiling bearing, and it is inner that self oiling bearing 1 is directly installed on valve body axis hole, bearing turnover place is dustproof by O type circle 2, and Gland 3 and rear end cover 4 endoporus places increase anti-wear gasket 5, simple in structure, friction factor is little, and moment of torsion is low, non-maintaining.
As shown in Figure 3, the valve seat on valve body and the adjusting pressing plate on spheroid all adopt Split type structure, and the valve seat 6 on valve body is all fixed by screw with the adjusting pressing plate 7 on spheroid, and it is convenient to install and change.
As shown in Figure 4, the whole pair eccentric structures that adopt of the eccentric all-ball valve of described full-bore rubber seal, during unlatching, rubber seal hightails sealing surface, wear and tear little, long service life.In figure, in x direction, between valve body center line 8 and axis hole center line 9, form the first bias 10; In y direction, between valve body center line 11 and axis hole center line 12, form the second bias 13.
