Abstract
The utility model discloses a shaft sleeve structure facilitating disassembly of a mechanical sealing. A non-compensation ring is arranged on one end of a shaft sleeve in sleeved mode, and an anti-rotating pin is arranged between the shaft sleeve and the non-compensation ring. An O-shaped circle one and an O-shaped circle two are arranged on the sealing position of the shaft sleeve and the non-compensation ring. A threaded through hole corresponding to the non-compensation ring is arranged on the other end of the shaft sleeve. An inner hexagon screw is arranged in the threaded through hole. The shaft sleeve structure facilitating disassembly of the mechanical sealing is simple in structure, and easy to achieve, solves the problem that the non-compensation ring of a static mechanical sealing is difficult to disassemble, and quickens overhaul schedule of devices, and sealing pieces are not easy to damage.
Description
Technical field
The utility model relates to the mechanical seal field, is 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.
The model utility content
The purpose of the utility model is to overcome above-mentioned not enough problem, and a kind of axle sleeve structure of being convenient to the mechanical seal dismounting is provided.
The utility model 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.
The characteristics of the utility model 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 the structural representation of the utility model;
Fig. 3 is that the utility model 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 utility model 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 between the two stop pin 2 is installed; Said axle sleeve 5 is equipped with O type circle 1, O type circle 23 with the sealing part of uncompensated ring 4; The corresponding uncompensated ring of the other end of said axle sleeve 54 places offer tapped through hole, and 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 are installed; General static mechanical seal as shown in Figure 1 has 2 seal points when equipment operation; Be O type circle 1, O type circle 23 places, thereby guarantee the mechanical seal proper functioning, and use the mechanical seal of the utility model that 3 seal points are arranged when equipment operation; Be 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 utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or changes according to the technological scheme of the utility model and model utility design thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
Claims (2)
