Abstract
The utility model discloses a kind of corrosion-resistant general plug sealing ring, comprise capsul, U-shaped lid and U-shaped spring, described capsul offers U-shaped annular groove, the two ends of described U-shaped lid are connected with the two ends of described U-shaped annular groove respectively, Packed containing space is formed between described U-shaped annular groove and described U-shaped lid, described U-shaped spring is arranged on described containing space, and the material that described capsul and described U-shaped lid adopt is polytetrafluoroethylmaterial material; Make the utility model that metal spring can be prevented to be subject to the erosion of strong corrosive media, and then improve working life and the sealing effect of general plug sealing ring.
Description
Technical field
The utility model relates to the technical field of seal ring, particularly relates to a kind of corrosion-resistant general plug sealing ring.
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, the stainless steel metal spring of general plug sealing ring, directly outside exposed, easily be subject to the erosion of strong corrosive media, although partial spring employs the good stainless steel model of corrosion resistance, still can suffer erosion in some cases, have a strong impact on working life and the sealing effect of general plug sealing ring, the Elgiloy alloy of import can be used for most corrosive environment, but price is high.
In view of this, the present inventor studies and devises a kind of corrosion-resistant general plug sealing ring, and this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of corrosion-resistant general plug sealing ring, prevents metal spring to be subject to the erosion of strong corrosive media, and then improves working life and the sealing effect of general plug sealing ring.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of corrosion-resistant general plug sealing ring, comprise capsul, U-shaped lid and U-shaped spring, described capsul offers U-shaped annular groove, the two ends of described U-shaped lid are connected with the two ends of described U-shaped annular groove respectively, Packed containing space is formed between described U-shaped annular groove and described U-shaped lid, described U-shaped spring is arranged on described containing space, and the material that described capsul and described U-shaped lid adopt is polytetrafluoroethylmaterial material.
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 seal ring.
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.
Because a kind of corrosion-resistant general plug sealing ring of the utility model have employed above-mentioned technological scheme, namely capsul, U-shaped lid and U-shaped spring is comprised, described capsul offers U-shaped annular groove, the two ends of described U-shaped lid are connected with the two ends of described U-shaped annular groove respectively, Packed containing space is formed between described U-shaped annular groove and described U-shaped lid, described U-shaped spring is arranged on described containing space, and the material that described capsul and described U-shaped lid adopt is polytetrafluoroethylmaterial material; 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 seal ring; 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; Make the utility model can solve metal spring and be easily subject to the problem that strong corrosive media corrodes, and then effectively improve working life and 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 corrosion-resistant general plug sealing ring, comprise capsul 1, U-shaped lid 2 and U-shaped spring 3, described capsul 1 offers U-shaped annular groove 4, the two ends of described U-shaped lid 2 are connected with the two ends of described U-shaped annular groove 4 respectively, form Packed containing space 5 between described U-shaped annular groove 4 and described U-shaped lid 2, described U-shaped spring 3 is arranged on described containing space 5, and the material that described capsul 1 and described U-shaped lid 2 adopt is polytetrafluoroethylmaterial material.
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 inboard of described seal ring.
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 3 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 4 opening is less than the width of described U-shaped spring 3 opening.
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 capsul of the present utility model and lid all have employed antiacid alkali and the good polytetrafluoroethylene (PTFE) material of solvent resistant, and metal spring is coated in the seal space between capsul and lid, make metal spring avoid being subject to the destruction of extraneous Korrosionsmedium, substantially increase working life of the present utility model and sealing effect.Thus, the utility model can be widely used in and have in corrosive media environment.
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.
