Abstract
The utility model discloses the general plug sealing ring of a kind of rotation, comprise capsul, spring and O RunddichtringO, described capsul inner side surface and running shaft interference fit, described capsul end face is provided with the first annular groove, described spring is located on described first annular groove, described spring and described first annular groove interference fit, and described capsul bottom periphery is provided with the second annular groove, described O RunddichtringO is located on described second annular groove, and the material that described capsul adopts is teflon or modified teflon material; The utility model under high pressure and aggressive medium environment, can be used as rotary seal, and then improve working life and the sealing effect of rotating seal ring.
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 rotation.
Background technique
Plug sealing ring is made up of polymeric material capsul and corrosion resistant stainless steel metal spring, seal ring is through running shaft, and be 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, 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, rotary seal adopts outside framework oil seal mostly, and the effect of oil sealing is exactly generally isolated with parts of exerting oneself by the parts needing in transmission part to lubricate, and is unlikely to allow oil seepage.Skeleton is just as the reinforcing bar inside concrete member, play the effect of reinforcement, and make oil sealing can keep shape and tension force, but the pressure of current most outside framework oil seal resistance toly can only be pressed onto below 0.03MPa, especially when high pressure, high temperature and High Rotation Speed, its wear resistance is bad, and corrosion resistance is poor.
In view of this, the present inventor studies and devises the general plug sealing ring of a kind of rotation, and this case produces thus.
Model utility content
The purpose of this utility model is that providing a kind of rotates general plug sealing ring, under high pressure and aggressive medium environment, can use as rotary seal, and then improves working life and the sealing effect of rotating seal 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 rotation, comprise capsul, spring and O RunddichtringO, described capsul inner side surface and running shaft interference fit, described capsul end face is provided with the first annular groove, described spring is located on described first annular groove, described spring and described first annular groove interference fit, and described capsul bottom periphery is provided with the second annular groove, described O RunddichtringO is located on described second annular groove, and the material that described capsul adopts is teflon or modified teflon 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 the inner side surface of described capsul.
As the optimal way of embodiment, the two ends, top of described first annular groove are respectively equipped with upper hem and lower hem.
Rotate general plug sealing ring because the utility model is a kind of and have employed above-mentioned technological scheme, namely capsul, spring and O RunddichtringO is comprised, described capsul inner side surface and running shaft interference fit, described capsul end face is provided with the first annular groove, described spring is located on described first annular groove, described spring and described first annular groove interference fit, described capsul bottom periphery is provided with the second annular groove, described O RunddichtringO is located on described second annular groove, and the material that described capsul adopts is teflon or modified teflon material; Described capsul comprises the first lip and the second lip, and described first lip and described second lip lay respectively at the inner side surface of described capsul; The two ends, top of described first annular groove are respectively equipped with upper hem and lower hem; Make the utility model can use and effectively tackle high pressure, aggressive medium environment under High Rotation Speed, 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 the general plug sealing ring of a kind of rotation, comprise capsul 1, spring 2 and O RunddichtringO 3, described capsul 1 inner side surface and running shaft interference fit, described capsul 1 end face is provided with the first annular groove 11, described spring 2 is located on described first annular groove 11, described spring 2 and described first annular groove 11 interference fit, described capsul 1 bottom periphery is provided with the second annular groove 12, described O RunddichtringO 3 is located on described second annular groove 12, described O RunddichtringO 3 effectively can prevent seepage, the material that described capsul 1 adopts is teflon or modified teflon material, teflon is a kind of macromolecular material of high-quality, can effectively solve corrosion-resistant and wear-resisting problem.
As the optimal way of embodiment, described capsul 1 comprises the first lip 13 and the second lip 14, described first lip 13 and described second lip 14 lay respectively at the inner side surface of described capsul 1, described first lip 13 and described second lip 14 directly contact with running shaft, further increase the sealing effect of capsul and running shaft.
As the optimal way of embodiment, the two ends, top of described first annular groove 11 are respectively equipped with upper hem 111 and lower hem 112, and spring can be fixed in described first annular groove by described upper hem 111 and described lower hem 112 preferably, plays sealed effect.
When using the utility model, the utility model is arranged on the place to be sealed on cylinder axis, the interference fit of capsul inner side surface and running shaft, capsul outer side surface relies on the side of spring forces first annular groove and sealing surface to produce interference fit, make the utility model can not seepage under High Rotation Speed, and O RunddichtringO further increases the function of leakage proof, in addition, capsul of the present utility model have employed antiacid alkali and the good polytetrafluoroethylene (PTFE) material of solvent resistant, capsul is made to have well corrosion-resistant and wear-resisting property, and then substantially increase working life of the present utility model and sealing effect.Thus, the utility model can be widely used in high pressure, high speed 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.
