Abstract
The invention discloses a dynamic seal structure of a position of a mechanical seal slippage diameter, which comprises an O-shaped ring, the slippage diameter and an O-shaped ring support. An arc-shaped groove is arranged on the contact portions of the seal structure and the O-shaped ring, the contact portions of the seal structure and the slippage diameter are in small interference fit, and the O-shaped ring support is arranged outside the O-shaped ring. The dynamic seal structure of the position of the mechanical seal slippage diameter is outstanding in safety, practicality and reliability, and the problem that a dynamic seal at the position of the mechanical seal slippage diameter is short in service life is solved.
Description
Technical field
The present invention relates to a kind of mechanical seal slippage diameter place movable sealing structure.
Background technique
In the existing technology, every cover mechanical seal all has frictional loss in spin friction; So every cover mechanical seal has also just had compensated loop and uncompensated ring, the compensated loop of mechanical seal all comes the slippage compensation through the slippage diameter, and the sealing at mechanical seal slippage diameter place is as a leak source of mechanical seal; Most important, generally adopt one O shape circle or one U-shaped circle or one cambridge ring to seal, though reached sealing effect; But the most important thing is the wriggling that mechanical seal brings; Cause the wearing and tearing of wearing and tearing of O shape circle or slippage place metalwork, this wearing and tearing cause the life-span of mechanical seal all very of short duration, in the method for slippage place metalwork surface coated with hard alloy; Alleviated the wearing and tearing of metalwork, but the wearing and tearing of O shape circle still are the keys in mechanical seal life-span.
Summary of the invention
The purpose of this invention is to provide a kind of mechanical seal slippage diameter place movable sealing structure.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of mechanical seal slippage diameter place movable sealing structure; Comprise that O shape circle, slippage diameter, O encircle holder; Said sealing configuration and O shape circle contact segment are provided with arc groove; Said sealing configuration is that slight interference cooperates with slippage diameter contact segment, and the holder of said O ring is arranged on outside the O shape circle.
Said slippage diameter is gone into Tou Chu and is provided with chamfering.
A kind of mechanical seal slippage of the present invention diameter place movable sealing structure, Security, practicability, reliability are comparatively outstanding, have solved short problem of mechanical seal slippage diameter place's motive sealing life-span.
Description of drawings
Fig. 1 is the structural representation of a kind of mechanical seal slippage of the present invention diameter place movable sealing structure.
Fig. 2 is the structural representation of a kind of mechanical seal slippage of the present invention diameter movable sealing structure O of place ring holder.
Among the figure: 1, O shape circle; 2, slippage diameter; 3, O ring holder.
Embodiment
As depicted in figs. 1 and 2, mechanical seal slippage diameter place movable sealing structure comprises O shape circle 1, slippage diameter 2, O ring holder 3; Sealing configuration and O shape are enclosed 1 contact segment and are provided with arc groove; Sealing configuration is that slight interference cooperates with slippage diameter 2 contact segments, and O ring holder 3 is arranged on the outside of O shape circle 1, moves the O shape ring recess degree of depth of diameter and deepens; After O shape circle is installed earlier, the holder of O ring is installed again.Install after the slippage diameter gone into head place's chamfering, if under the situation of conditions permit, in order to increase the wear resistance of metalwork, can be on the surface of slippage diameter the coated with hard alloy.
Claims (2)
1. mechanical seal slippage diameter place movable sealing structure; It is characterized in that: comprise that O shape circle, slippage diameter, O encircle holder; Said sealing configuration and O shape circle contact segment are provided with arc groove, and said sealing configuration is that slight interference cooperates with slippage diameter contact segment, and the holder of said O ring is arranged on outside the O shape circle.
2. a kind of mechanical seal slippage diameter according to claim 1 place movable sealing structure, it is characterized in that: said slippage diameter is gone into Tou Chu and is provided with chamfering.
