Description
Technical field
The utility model relates to the technical field of seal ring, particularly relates to the general plug sealing ring of a kind of dual spring.
Background technique
General plug sealing ring is made up of polymeric material capsul and corrosion resistant stainless steel metal spring, seal ring is arranged in groove, spring pressurized, form outside tension force, the sealing lip at capsul top is impelled to be close to groove, because spring forever provides elastic force to sealing lip, the bias of capsul wearing and tearing and mating parts can be made up, form the sealing in from vacuum to low pressure range thus, system pressure meeting secondary spring accumulation of energy in addition, pressure is larger, and it is more abundant that sealing lip and groove are fitted, and forms high pressure sealing thus.General plug sealing ring is widely used in pump, valve, compressor, pharmaceutical equipment and field of petrochemical industry.
In prior art, for the situation that installing space is larger, namely the situation that two sealing surface gap ratios are larger, because the specifications and models of spring are limited, normal conditions are that the U-shaped annular groove two ends of mounting spring are thicker, and U-shaped annular groove internal diameter is just smaller, the sealing lip that spring forces two ends like this are thicker, so that oppressive force is limited, does not have good sealing effect.
In view of this, the present inventor studies and devises the general plug sealing ring of a kind of dual spring, and this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of dual spring general plug sealing ring, for the situation that two sealing surface gap ratios are larger, can guarantee that spring is supplied to the enough oppressive forces of capsul lip, and then improve the sealing effect of general plug sealing ring.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
The general plug sealing ring of a kind of dual spring, comprise capsul and U-shaped spring, described capsul end face offers two U-shaped annular grooves arranged side by side, and two described U-shaped springs are located in described two U-shaped annular grooves respectively, and the opening of described U-shaped spring all points to outside.
As the optimal way of embodiment, described capsul comprises the first lip and the second lip, and described first lip and described second lip lay respectively at outside and the inboard of described capsul.
As the optimal way of embodiment, the outer surface of described first lip and described second lip is respectively equipped with the first broken line projection and the second broken line projection.
As the optimal way of embodiment, described U-shaped spring comprises the Flat belt of dentation, and the cross section of described Flat belt is U-shaped, and the Flat belt two ends of described dentation are connected to form annulus.
As the optimal way of embodiment, the width of described U-shaped annular groove opening is less than the width of described U-shaped spring opening.
As the optimal way of embodiment, the material that described capsul adopts is polytetrafluoroethylmaterial material.
Because the general plug sealing ring of a kind of dual spring of the utility model have employed above-mentioned technological scheme, namely capsul and U-shaped spring is comprised, described capsul end face offers two U-shaped annular grooves arranged side by side, two described U-shaped springs are located in described two U-shaped annular grooves respectively, the opening of described U-shaped spring all points to outside, described capsul comprises the first lip and the second lip, described first lip and described second lip lay respectively at outside and the inboard of described capsul, and the outer surface of described first lip and described second lip is respectively equipped with the first broken line projection and the second broken line projection; The outer surface of described first lip and described second lip is respectively equipped with the first broken line projection and the second broken line projection; The utility model provides two springs, add the width of seal ring on the one hand, the occasion that two sealing surfaces are wider can be applied to, on the other hand, the thickness of the first lip and the second lip becomes thinner compared with prior art, two springs can provide good oppressive force simultaneously, and then effectively improve the sealing effect of general plug sealing ring.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of dual spring circle, comprises capsul 1 and U-shaped spring 2, and described capsul 1 end face offers two U-shaped annular grooves 3 arranged side by side, two described U-shaped springs 2 are located in described two U-shaped annular grooves 3 respectively, and the opening of described U-shaped spring 2 all points to outside.
As the optimal way of embodiment, described capsul 1 comprises the first lip 11 and the second lip 12, and described first lip 11 and described second lip 12 lay respectively at outside and the general plug sealing inboard of described capsul 1.
As the optimal way of embodiment, the outer surface of described first lip 11 and described second lip 12 is respectively equipped with the first broken line projection 111 and the second broken line projection 121.
As the optimal way of embodiment, described U-shaped spring 2 comprises the Flat belt of dentation, and the cross section of described Flat belt is U-shaped, and the Flat belt two ends of described dentation are connected to form annulus.
As the optimal way of embodiment, the width of described U-shaped annular groove 3 opening is less than the width of described U-shaped spring 2 opening.
As the optimal way of embodiment, the material that described capsul 1 adopts is polytetrafluoroethylmaterial material.
When using the utility model, the utility model is arranged on the place to be sealed on cylinder axis, system pressure and spring pressure impel described first lip and described second lip tightly to touch sealing surface, because the utility model have employed two springs, add the width of seal ring on the one hand, the occasion that two sealing surfaces are wider can be applied to, on the other hand, the thickness of the first lip and the second lip becomes thinner compared with prior art, so that two springs provide better oppressive force simultaneously, and then can effectively improve the sealing effect of general plug sealing ring.Thus, the utility model can be widely used in the wider occasion of two seal f ace widths of general plug sealing ring to be installed, guarantees that dual spring provides better oppressive force to seal lip.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited successively, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
