Abstract
The invention discloses a shaft sleeve structure convenient for detachment of mechanical seal. An un-compensated ring is sleeved at one end of a shaft sleeve, an anti-rotation pin is mounted between the shaft sleeve and the un-compensated ring, a first O-shaped ring and a second O-shaped ring are mounted at the seal joint of the shaft sleeve and the un-compensated ring, a threaded through hole is arranged at the other end of the shaft sleeve corresponding to the un-compensated ring, and an inner hexagonal screw is mounted in the threaded through hole. The shaft sleeve structure is simple in structure and easy to realize, the difficulty in detachment of the un-compensated ring of the static mechanical seal is overcome, damage of seal parts is not easy to cause, and repairing schedule of equipment is accelerated.
Description
Technical field
The present invention relates to the mechanical seal field, be specifically related to a kind of axle sleeve structure of being convenient to the mechanical seal dismounting.
Background technique
Mechanical seal is widely used in the rotating equipment of all trades and professions; And when overhaul of the equipments, often to carry out strip inspection to mechanical seal, this has just related to the dismounting problem of mechanical seal, and is as shown in Figure 1; The uncompensated ring of static mechanical seal is contained on the axle sleeve; Because O type circle effect between the two makes that uncompensated ring is difficult to back off, if be easy to damage uncompensated ring again with rough power; And the complexity of dismounting has directly influenced the progress of maintenance, and this just needs a kind of easy-to-dismount mechanical seal structure to solve this difficult problem.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of axle sleeve structure of being convenient to the mechanical seal dismounting is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of axle sleeve structure of being convenient to the mechanical seal dismounting; It is characterized in that: an end of axle sleeve is set with uncompensated ring; And stop pin is installed between the two; The sealing part of said axle sleeve and uncompensated ring is equipped with O type circle one, O type circle two, and the corresponding uncompensated ring of the other end of said axle sleeve place offers tapped through hole, in the said tapped through hole socket head screw is installed.
Between said socket head screw and the axle sleeve pad is installed.
Characteristics of the present invention are: simple in structure, be convenient to realize, and solved the problem of the uncompensated ring difficulty or ease dismounting of static mechanical seal, be difficult for causing the damage of Sealing, accelerated the overhaul of the equipments progress.
Description of drawings
Fig. 1 is the uncompensated ring of general static mechanical seal and the structural representation between the axle sleeve;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is that the present invention is installed in the schematic representation in the static mechanical seal.
Wherein: 1, O type circle 1, pin 3, O type circle 24, uncompensated ring 5, axle sleeve 6, pad 7, socket head screw.
Embodiment
Like Fig. 2, shown in 3, the present invention is a kind of axle sleeve structure of being convenient to the mechanical seal dismounting, and an end of axle sleeve 5 is set with uncompensated ring 4; And stop pin 2 is installed between the two, and said axle sleeve 5 is equipped with O type circle 1, O type circle 23 with the sealing part of uncompensated ring 4, and the corresponding uncompensated ring of the other end of said axle sleeve 54 places offer tapped through hole; Socket head screw 7 is installed in the said tapped through hole; Between said socket head screw 7 and the axle sleeve 5 pad 6 is installed, general static mechanical seal as shown in Figure 1 has 2 seal points when equipment operation, i.e. O type circle 1, O type circle 23 places; Thereby guarantee the mechanical seal proper functioning; And use mechanical seal of the present invention that 3 seal points are arranged when equipment operation, promptly O type circle 1, O type circle 23, pad 6 places guarantee that mechanical seal can be as the same proper functioning of static mechanical seal.
When dismounting static mechanical seal uncompensated ring 4, only need pull down socket head screw 7 and pad 6 earlier, can very easily take off uncompensated ring 4 with general utility tool again, and be difficult for causing damage.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
Claims (2)
1. be convenient to the axle sleeve structure that mechanical seal is dismantled for one kind; It is characterized in that: an end of axle sleeve (5) is set with uncompensated ring (4); And stop pin (2) is installed between the two; Said axle sleeve (5) is equipped with O type circle one (1), O type circle two (3) with the sealing part of uncompensated ring (4), and the corresponding uncompensated ring of the other end of said axle sleeve (5) (4) locates to offer tapped through hole, and socket head screw (7) is installed in the said tapped through hole.
2. the axle sleeve structure of being convenient to the mechanical seal dismounting as claimed in claim 1 is characterized in that: between said socket head screw (7) and the axle sleeve (5) pad (6) is installed.
