Abstract
The utility model discloses an external sealing device of a bellows compensator and relates to a sealing device. The external sealing device comprises a fixed plate (1), a bellows (2), a sheath (3), asealing ring (4), a piston (5), a pressure plate (6), an end cover (7), a screw (8) and a nozzle (9), wherein the nozzle (9) is closely arranged at one end of the bellows (2); the fixed plate (1) isarranged on the outer wall of the nozzle (9); the piston (5) is arranged at the outer side of the nozzle (9) and is close to the fixed plate (1); the pressure plate (6) is connected with the piston (5) through the screw (8); the sealing ring (4) is arranged between the piston (5) and the pressure plate (6); the sheath (3) is arranged at the outer side of the bellows compensator; and the end cover(7) is matched with the port of the sheath (3). The external sealing device can protect the outer wall of the bellows of the bellows compensator against corrosion.
Description
Technical field:
The utility model relates to a kind of seal arrangement, especially a kind of external corrugated expansion joint seal arrangement.
Background technique:
Corrugated expansion joint is widely used in the various pipes and the equipment of industries such as city heat supply, electric power, oil, chemical industry, metallurgy, light industry.It not only can compensate pipeline axial displacement and lateral displacement, can also absorb the dither that machinery causes, solves that pipeline is various can not survey the variation that external cause (as earthquake etc.) brings.Make between the pipeline and pipeline has been realized flexible the connection with equipment room.Remove the compensation problem that solves pipeline enclosure, but also have compact structure, safe and reliable, long service life, advantages such as installation and maintenance convenience.But, some corrosive gass in oil, the chemical enterprise or liquid can cause corrosivity to destroy the equipment of periphery, and wherein, the corrosion-vulnerable of the bellows in the corrugated expansion joint causes the accident, though this situation can take certain measure to alleviate, and can not tackle the problem at its root.
The model utility content:
The purpose of this utility model provides a kind of external corrugated expansion joint seal arrangement, and it can protect the bellows outer wall corrosion-vulnerable not in the corrugated expansion joint, and does not influence the original function of corrugated expansion joint.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is by fixed plate 1, bellows 2, sheath 3, seal ring 4, piston 5, pressing plate 6, end cap 7, screw 8 and take over 9 and form, adapter 9 closely is arranged on an end of bellows 2, fixed plate 1 is arranged on the outer wall of adapter 9, piston 5 is arranged on the outside of adapter 9 near fixed plate 1, pressing plate 6 is connected with piston 5 by screw 8, seal ring 4 is arranged between piston 5 and the pressing plate 6, sheath 3 is arranged on the corrugated expansion joint outside, and end cap 7 cooperates with the port of sheath 3.
Described seal ring 4, piston 5, pressing plate 6 and screw 8 are formed seal.
The utility model can be protected the bellows outer wall corrosion-vulnerable not in the corrugated expansion joint, and does not influence the original function of corrugated expansion joint.
Description of drawings:
Fig. 1 is a mounting structure schematic representation of the present utility model, and Fig. 2 is the J portion enlarged diagram of Fig. 1.
Embodiment:
With reference to Fig. 1-2, this embodiment is by the following technical solutions: it is by fixed plate 1, bellows 2, sheath 3, seal ring 4, piston 5, pressing plate 6, end cap 7, screw 8 and take over 9 and form, adapter 9 closely is arranged on an end of bellows 2, fixed plate 1 is arranged on the outer wall of adapter 9, piston 5 is arranged on the outside of adapter 9 near fixed plate 1, pressing plate 6 is connected with piston 5 by screw 8, seal ring 4 is arranged between piston 5 and the pressing plate 6, sheath 3 is arranged on the corrugated expansion joint outside, and end cap 7 cooperates with the port of sheath 3.
Described seal ring 4, piston 5, pressing plate 6 and screw 8 are formed seal.
This embodiment can be protected the bellows outer wall corrosion-vulnerable not in the corrugated expansion joint, and does not influence the original function of corrugated expansion joint.
