Abstract
The utility model discloses a gland for static mechanical seal structures, which comprises a ring, both ends of the ring are respectively provided with an extended end, the extended ends are respectively provided with a strip-shaped bolt hole, and the inner wall of the ring is provided with a stepped recess. The integrated seal ring design of the gland can enhance the stability of a seal under high temperature and high pressure, the drive sealing area of the seal ring is large, the injury of the seal ring in sticky liquid can be prevented when equipment is started or shut down, and thereby the service life of the seal is effectively guaranteed.
Description
Technical field
The utility model relates to the mechanical sealing technology field, specifically belongs to a kind of state type mechanical seal structure and uses gland.
Background technique
Mechanical seal is meant the device that prevents escape of liquid that is made up of keeping applying and slide relative under the effect of hydrodynamic pressure and compensation mechanism elastic force (or magnetic force) and under the cooperation of auxiliary seal perpendicular to the end face of spin axis at least one pair of.Elastic force load maintainer and auxiliary seal be metallicity line pipe mechanical seal we be called the wavy metal seal of tube.In light seal, use rubber corrugated pipe to make auxiliary seal in addition, rubber corrugated pipe elastic force is limited, generally need be aided with spring and satisfy and load elastic force.Present mechanical seal generally is divided into: single end face, Double End mode, but structural design is reasonable inadequately.
The model utility content
The purpose of the utility model provides a kind of state type mechanical seal structure and uses gland; The design of integral sealing ring; Improve and be sealed in the stability under the HTHP; It is big that seal ring drives sealing area, prevents the damage that start equipment startup-shutdown seal ring causes in viscous liquid, effectively guaranteed the working life of sealing.
The technological scheme of the utility model is following:
A kind of state type mechanical seal structure is used gland, includes ring body, and the two ends of ring body have extending end respectively, has the bolt hole of bar shaped on the extending end, has step-like deep gouge on the inner wall of ring body.
The outboard shafts of described ring body is domatic to having.
The integral sealing ring design of the utility model, raising is sealed in the stability under the HTHP, and it is big that seal ring drives sealing area, prevents the damage that start equipment startup-shutdown seal ring causes in viscous liquid, effectively guaranteed the working life of sealing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; A kind of state type mechanical seal structure is used gland, includes ring body 1, on ring body suit and the axis body 6; The two ends of ring body 1 have extending end 2 respectively; Have the bolt hole 3 of bar shaped on the extending end 2, have step-like deep gouge 4 on ring body 1 inwall, the outboard shafts of ring body is to having domatic 5.
Claims (2)
1. a state type mechanical seal structure is used gland, includes ring body, it is characterized in that: the two ends of ring body have extending end respectively, have the bolt hole of bar shaped on the extending end, have step-like deep gouge on the inner wall of ring body.
2. state type mechanical seal structure according to claim 1 is used gland, it is characterized in that: the outboard shafts of described ring body is domatic to having.
