Abstract
The utility model relates to a kind of pump opening seal ring, belongs to fluid machinery field of sealing technology.Opening seal ring of the present utility model, the agent structure of sealing circle is rectangle circle structure, and a side ring surface of rectangle annulus inwardly has circular groove vertically, along extending flanging respectively to interior in the both sides of this circular groove, under free state, the flanging of circular groove both sides is outwards opened.The circular groove inner circumferential of described opening seal ring is evenly equipped with the open splinter matched with shape in annular groove width direction.Opening seal ring of the present utility model, good sealing effect is easy for installation, seal ring can Reusability, achieves and carries out effective sealing to the annular contact surface intersected vertically.
Description
Technical field
The utility model relates to a kind of pump opening seal ring, belongs to fluid machinery field of sealing technology.
Background technique
The flow passage components structure of certain Pulp pump, as shown in Figure 1, spiral case 1 rear end connects to form impeller working cavity by backplate 3 and pump shaft, encapsulated by pump case 4 outside spiral case 1 and backplate 3, spiral case 1 and connecting part, outer, backplate 3 rear end are designed to the circular orientation face of the two end face, spiral case 1 is connected with the screens of pump case 4 inwall with the end in the circular orientation face of backplate 3, make the surface of contact between spiral case 1 and backplate 3, and the surface of contact between the circular orientation face of spiral case 1 and connecting part, outer, backplate 3 rear end and pump case 4 inwall, form the annular contact surface intersected vertically; For avoiding working solution to reveal to impeller working cavity rear end, need the surface of contact intersected vertically at this to seal, conventional construction realizes by arranging O-ring seals or rectangular seal in the intersection location of the surface of contact that intersects vertically.
Because O-ring seals or rectangular seal are solid construction, decrement is limited, sealing effect requires higher to the axial dimension of seal ring, if axial dimension design is too small, medium will along sealing face leakage, cause seal failure, if axial dimension design is excessive, decrement is excessive, and rubber cannot recover elasticity, after tearing pump or replacing spare part open, seal ring cannot continue to use; In addition, upper half part of the end difference compresses seal in spiral case 1 and backplate 3 rear end two circular orientation faces and lower half portion, when the axial dimension tolerance in two circular orientation faces is larger, easily cause seal ring decrement uneven, cause the circular orientation you face effective sealing that seal ring can only be larger to one of them axial dimension, the sealing effect in opposite side circular orientation you face is poor, is difficult to the requirement reaching integral sealing.
Model utility content
The purpose of this utility model is when solving the seal ring of conventional construction for sealing the annular contact surface intersected vertically, the problems such as poorly sealed, installation is inconvenient, seal ring cannot be reused, seal ring decrement is uneven can be caused, and a kind of pump opening seal ring provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pump opening seal ring of the present utility model, the agent structure of sealing circle is rectangle circle structure, and a side ring surface of rectangle annulus inwardly has circular groove vertically, along extending flanging respectively to interior in the both sides of this circular groove, under free state, the flanging of circular groove both sides is outwards opened.
The circular groove inner circumferential of described opening seal ring is evenly equipped with the open splinter matched with shape in annular groove width direction, while ensureing that seal ring has certain decrement, be unlikely to again to make the aging distortion of opening rubber sealing ring when decrement is too large, lose sealing effect.
When opening seal ring of the present utility model is used for the annular contact surface intersected vertically, it is relative with the end face of two circular orientation platforms that seal ring has circular groove side, the flanging of seal ring circular groove both sides is under the pressuring action in two circular orientation you faces, compress respectively in circular groove, the end face of two independent circular orientation platforms to contact separately of flanging seals, and there will not be both sides unbalance stress to cause the phenomenon of side sealing effect difference.
Beneficial effect
Opening seal ring of the present utility model, good sealing effect is easy for installation, seal ring can Reusability, achieves and carries out effective sealing to the annular contact surface intersected vertically.

Embodiment
Below in conjunction with drawings and Examples, content of the present utility model is further described:
Embodiment
A kind of pump opening seal ring of the present utility model, as shown in Figure 4, the agent structure of sealing circle is rectangle circle structure, one side ring surface of rectangle annulus inwardly has circular groove vertically, along extending flanging respectively to interior in the both sides of this circular groove, under free state, the flanging of circular groove both sides is outwards opened.
As shown in Figure 3, described opening seal ring circular groove inner circumferential is evenly equipped with the open splinter matched with shape in annular groove width direction, while ensureing that seal ring has certain decrement, be unlikely to again to make the aging distortion of opening rubber sealing ring when decrement is too large, lose sealing effect.
As shown in Figure 2, when opening seal ring 2 of the present utility model is used for the sealing structure of certain flow passage component of slurry pump, the end face that seal ring has the circular orientation face of circular groove side and spiral case 1 and connecting part, outer, backplate 3 rear end is relative, the flanging of seal ring circular groove both sides is under the pressuring action in two circular orientation you faces, compress respectively in circular groove, the end face of two independent circular orientation platforms to contact separately of flanging seals, and there will not be both sides unbalance stress to cause the phenomenon of side sealing effect difference.
