Abstract
The invention relates to a compensation ring component for a spring mechanical seal device, comprising a compensation ring base (21), a spring (22), a loop (23), a sealing ring (24), a friction ring (25) and an anti rotation peg (26). The compensation ring component for a spring mechanical seal device has the advantages of simple and reasonable structure, reliable combination, smooth operation ofthe friction ring, safe and reliable operation, preventing pollution of the spring from medium, applicability to higher working condition and facility for transportation and installation thanks to anintegrated structure.
Description
Technical field
What the present invention relates to is mechanical seal device, particularly the compensated loop member of spring mechanical sealing device.
Background technique
Mechanical seal device is a kind of seal arrangement that prevents that working fluid from leaking along running shaft, mechanical seal device claims face seals again, by a pair of rotating ring and stationary ring perpendicular to axis, and rotating ring (compensated loop) its end face and stationary ring end face keep the applying slip formation that is rotatably assorted down in elastic compensating (spring) mechanism effect.Rotating ring is connected with shaft drive, and stationary ring is connected with end cap, pays the slide relative rotation by rotating ring and stationary ring friction and finishes the rotation axis seal effect.
Existing spring type mechanical sealing compensated ring component (ginseng accompanying drawing 1) generally is made of compensated ring adaptor 1, spring 2, throw-out collar 3, seal ring 4, friction ring 5, jump ring 6.Spring 2, throw-out collar 3, seal ring 4, friction ring 5 are contained in compensated ring adaptor 1 inner chamber successively, and the outer end is by jump ring 6 location, and compensated ring adaptor 1 couples together all parts of compensated ring component, and is fixed on the equipment by Cock screw 7.Spring 2 elastic force are delivered to seal ring 4 and friction ring 5 by throw-out collar 3, are that friction ring 5 and uncompensated ring fit tightly thereby make compensated loop.It becomes as a whole in order to make whole compensated ring component, prevents that friction ring 5 breaks away from compensated ring adaptor 1 under the effect of spring 2 elastic force, adopts jump ring 6 that friction ring 5 is installed in the compensated ring adaptor 1.This kind structure jump ring 6 is inlaid in the groove of compensated ring adaptor 1, blocks friction ring 5 and spring 2 by jump ring 6 and reaches collection dress purpose.This structure stability is lower.When equipment ran up, jump ring 6 threw away easily, causes mechanical failure.Impurity in the medium enters into compensated ring adaptor 1 inner chamber easily and produces obstruction in addition, influences spring 2 proper functioning.
The purpose of this invention is to provide a kind of rational in infrastructure, conformability good, compensated ring component of spring mechanical sealing device safe and reliable to operation.
Summary of the invention
The present invention includes compensated ring adaptor 21, spring 22, ring set 23, seal ring 24, friction ring 25, stop pin 26 constitutes, spring 22 is installed in ring cavity the inner of compensated ring adaptor 21, ring set 23 is connected with the front port seam secure fit of compensated ring adaptor 21, friction ring 25 cooperates installation by seal ring 24 with ring set 23, act at the ring cavity inner spring 22 of compensated ring adaptor 21 and the inner table top 25 ' and ring set 23 interior edge faces 23 ' of friction ring 25, spring 22 promotes friction ring 25 reaches and compensates, ring set 23 interior edge faces 23 ' make spring 22 spacing, are provided with stop pin 26 in friction ring 25 the inners and 21 of compensated ring adaptors.
The present invention is simple and reasonable, cooperates reliably, and friction ring 25 runnings steadily, good with uncompensated ring friction ring conformability, not only avoided prior art to adopt the jump ring structure when equipment runs up, the danger that jump ring is deviate from easily makes total more safe and reliable.And friction ring 25 does not have rigid connection to cooperate in the structure, and to friction ring 25 not damageds, its collection assembling structure is convenient to transportation and is installed.
In addition, compensated ring adaptor 21 bore seal, the protection spring has improved application reliability and application power not by medium pollution, can be applicable to that higher work condition environment uses.

Embodiment
The present invention includes compensated ring adaptor 21, spring 22, ring set 23, seal ring 24, friction ring 25, stop pin 26 constitutes, spring 22 is installed in ring cavity the inner of compensated ring adaptor 21, ring set 23 is fixedlyed connected with the front port seam interference fit of compensated ring adaptor 21, friction ring 25 cooperates installation by seal ring 24 with ring set 23, spring 22 acts on the inner table top 25 ' and ring set 23 interior edge faces 23 ' of friction ring 25, spring 22 promotes friction ring 25 reaches and compensates, ring set 23 interior edge faces 23 ' make spring 22 spacing, are provided with stop pin 26 in friction ring 25 the inners and 21 of compensated ring adaptors.
Shown in accompanying drawing 2 first half structure embodiments, spring 22 is corrugated sheet springs, and the front-end face of corrugated sheet spring 22 inner table top 25 ' and ring set 23 interior edge faces 23 ' direct and friction ring 25 act on, and promote friction ring 25 reaches and compensate.Stop pin 26 prevents that friction ring 25 from rotating relative to compensated ring adaptor 21, when corrugated sheet spring 22 makes friction ring 25 in working order and uncompensated ring keep to fit.Ring set 23 interior edge faces 23 ' are limited to corrugated sheet spring 22 in the compensated ring adaptor 21, and whole compensated ring component is become one.
Shown in the accompanying drawing 2 Lower Half structure embodiments, spring 22 is helical springs, is provided with throw-out collar 27 at helical spring 22 front ends, and helical spring 22 is by inner table top 25 ' and the ring set 23 interior edge faces 23 ' effect of throw-out collar 27 with friction ring 25.
