Abstract
The utility model relates to a mechanical seal technical field is a sealed with endwise slip can radially rotate, including having the polytetrafluoroethylene outer lane of " U " type recess, the outward flange has a barb in the recess, and embedded have a continuous N type stainless steel spring circle. The utility model discloses a high pressure resistant embedded stainless steel mechanical seal circle that deforms designs the recess on pure polytetrafluoroethylene's basis for the stainless steel spring circle can be embedded in the sealing member, guarantees sealed effect, has promoted the high pressure resistant and stand wear and tear ability of sealing member greatly, and then the life of extension sealing member, satisfies the operation requirement, has realized also that the sealing washer can radially rotate and axial displacement on the axis body, has increased mechanical seal's practical scope.
Description
Technical field
The field that this utility model relates to is the movable sealing ring field in mechanical sealing member.
Background technology
1. being "O"-ring or outside framework oil seal etc. at original mechanical seal ring majority, its structure is all single, bears radial pressure and axial compressive force is different from, and has been partial to and is all fixed or the most motionless or the most motionless.
2. outside framework oil seal is due to relatively cracky in its characteristic installation process, causes the effect sealed to be had a greatly reduced quality.
The most original sealing ring uses politef, owing to its hardness is big and extensibility (flexible) is little, does not has Rational structure, it is impossible to play good sealing effectiveness.
The most original "O"-ring or its structure constraint of outside framework oil seal are in cannot be in the environment of resistance to dynamic high temperature, such as temperature be continually changing between-40 ~ 200 DEG C, and its original "O"-ring or outside framework oil seal cause seal failure owing to expanding with heat and contract with cold.
Summary of the invention
The purpose of this utility model is to overcome appeal weak point of the prior art to provide a kind of good sealing effect, it is easily installed, resistance to dynamic high temperature, and the mechanical seal ring that can axially and radially move, this sealing ring includes: the politef outer ring of band " U " type groove, N continuous type stainless steel spring circle.
1. one kind can radial rotating and seal in axial sliding, politef outer ring (1) including " U " type groove, there is the protuberance (1-1) higher than Internal and external cycle diameter 15 ° in described " U " type groove politef outer ring (1) outside with inside upper part, groove inward flange is provided with barb (1-3), the barb (1-3) of described groove inward flange is for fixing N continuous type stainless steel spring circle (3) being embedded in groove, and described N continuous type stainless steel spring circle (3) is fitted in " U " type groove politef outer ring (1) by bending.
2. the one described in can radial rotating and sealing in axial sliding, it is characterized in that: described N continuous type stainless steel spring circle (3) fitted in " U " type groove politef outer ring (1) has and increases the deformability of sealing ring and endurance so that sealing ring can on axis body radial rotating with move axially.
3. the one described in can radial rotating and sealing in axial sliding, it is characterized in that: described " U " type groove politef outer ring (1) outside and inside upper part have support force produced by protuberance (1-1) and N continuous type stainless steel spring circle (3) being embedded in groove higher than Internal and external cycle diameter 15 ° to interact.
4. the stainless steel spring circle (3) described in, is characterized in that: use stainless steel spring slice stamping to form.Wherein, support in N continuous type stainless steel spring circle fits in politef outer ring " U " type groove by bending and by the barb in groove is fixing, in " U " type groove type, form inside and outside Bidirectional supporting power.
Use stainless steel spring, the support force of lasting stability can be brought so that the service life of sealing ring is greatly extended, and the dynamic produced frictional force dynamic with axle in footpath can be born, be suitable for more changeable sealed environment.
Accompanying drawing explanation
Accompanying drawing is as follows:
Fig. 1 is complete seal circle cross-sectional view；
Fig. 2 is band " U " type groove politef outer ring cross-sectional view；
Fig. 3 is N continuous type stainless steel spring circle bending sketch map；
Fig. 4 is that N continuous type stainless steel spring circle launches plane graph；
Accompanying drawing number: protuberance (1-1)；Seam outer rim (1-2)；Barb (1-3)；The barb (1-3) of groove inward flange；N-type stainless steel spring circle top (3-3)；U angle (3-1), (3-2).
Detailed description of the invention
In conjunction with accompanying drawing, this utility model detailed description of the invention is described in detail in detail, specifically describe as a example by the model sealing as 30*20*6: shown by Fig. 1, include the politef circle (1) of " U " type groove, outer upper have in 4 millimeters sentence the angle of 15 ° obliquely to seam outer rim (1-1) higher than Internal and external cycle diameter, its effect is that laminating support plays sealing inboard wall of base, groove inside upper part has in 4 millimeters of angles sentencing 15 ° obliquely to seam outer rim (1-2), its effect is to play seal shaft external diameter in interference fit with rotating shaft, ensure that liquid or gas are not revealed at axle external diameter；" U " type groove inner edge is provided with barb (1-3), the barb (1-3) of described groove inward flange is to enclose (3) for the fixing N continuous type stainless steel spring U being embedded in groove, barb (1-3) to now groove inward flange combines with N-type stainless steel spring circle top (3-3), just can play the function of fixing N continuous type stainless steel spring circle (3)；N continuous type stainless steel spring circle (3) fits in " U " type groove politef inner ring (1) by bending, the U angle of U circle is more than 10 ° of U angles (3-1) of angle and the U angle (3-2) of original politef U circle, to ensure that stainless steel spring U circle in expansion and props up politef inner ring, play internal diameter and external diameter has the identical power of being adjacent to simultaneously, so that turn struts the most simultaneously, it is ensured that inner ring and outer ring have strong sealing effect.
Stainless steel spring U circle has the deformability of memory metal, is perfectly applied in U-shaped sealing so that this sealing exceeds about 5 times than normal sealing service life, and has better seal effect.
This structure and material can allow sealing do relative circular movement along with axle and support, namely moves as mechanical seal, and ensures sealing effectiveness；Laterally bend according to the mode shown in Fig. 3 because of N continuous type stainless steel spring circle (3) and embed in " U " type groove politef circle (1), described stainless steel spring circle (3), it is characterized in that: use stainless steel spring slice stamping to form, can play and seal with moving axially relative, namely play piston like motion；Have and increase the deformability of sealing ring and the effect of endurance so that sealing ring is capable of on axis body radial rotating and moves axially, and has broken single sealing and can only fix the routine of use.
This invention achieve the high temperature resistant and resistance to dynamic high temperature of politef, high pressure resistant, can the function such as deformation.
In sum, this utility model simplifies the making structure of mechanical seal ring, decrease the unnecessary breakage brought in installation process, realize single seal can with moving axially relative and while radial rotating structure, it is greatly improved deformability and the life-span of sealing ring, breakthrough on the basis of original stationary applications add dynamic application function, make field of sealing technology more diversification, above are only the detailed description of the invention of the present invention, but the design concept of the present invention is not limited to and this, all utilize this design that the present invention is carried out substantial transformation, belong to invade the behavior of scope.
