Abstract

The utility model discloses a pipeline compensator, which includes a compensator locking flange, an obturating ring, and a flange bolt. An inclined conic obturating surface is arranged on the corner where the obturating surface contact the inside of two flange pieces positioned on the end of the compensator, a pipeline compensator drawtube is arranged on the end abutting against the compensator locking flange, and a conic main pipeline connector is arranged on the other end of the drawtube. In addition, a sidestep-shaped heave is arranged on the inner side of the two flange pieces abutting against the outer side of the inclined conic obturating surface. The utility model can be installed conveniently, can be clamped on the main pipeline fast no matter at anywhere, and is hard to leak within the transfusion pressure of 2.0 MPa. When the obturating ring is abraded, the flange bolt only needs to be screwed close to lead the inclined conic obturating surface to compress the obturating ring inwards, further can enable the obturating ring to be clamped on the main pipeline close and keep on playing the obturating role, so that the service life of the compensator is prolonged, and the transfusion pressure in the pipe is improved.

Description

Pipeline compensator
Technical field
The utility model relates to the compensation device that a kind of liquid-transport pipe-line is provided with because of expanding with heat and contract with cold, especially a kind of flexible process longer pipe road compensator.
Background technique
Industrial liquid-transport pipe-line often route is very long, as when expanding with heat and contract with cold, is easy to produce fracture, and people just manage pipe laying compensator on pipeline, with anti-fracture and leak.Existing compensator is that " O " type rubber seal is enclosed within the tube wall interlayer between compensator and the main pipe, is made main pipe flexible naturally.This compensator in use has some inconvenience:
1, ground easily produces and leaks not at ordinary times.
2, easy leakage when transfusion working pressure 0.2MPa.
3, " O " type circle is easily aging.
4, be not easy to install and change.
Summary of the invention
Technical problem to be solved in the utility model, be to provide a kind of easy for installation, simple and reliable, working life longer pipe road compensator.
As follows for solving the technological scheme that above technical problem adopts: the utility model comprises compensator locking flange, seal ring, flange bolt, it is characterized in that: the inboard and contacted corner of seal ring at the every flange that is positioned at the compensator end, be provided with the tilted conical sealing surface, be provided with the pipeline compensator telescopic pipe at a end, be provided with taper main pipe connecting body at the other end of telescopic pipe near compensator locking flange.In addition, inboard and at every locking flange near the lateral direction of tilted conical sealing surface, be provided with a stepped shape projection.
Because adopt above technological scheme, its effect is conspicuous:
1, install easily, and long service life.
2, be not easy to produce leak of liquid.
3, scalable process is longer.
4, can improve infusion pressure to 2.0MPa and difficult generation leakage.
Description of drawings
Fig. 1 is a sectional arrangement drawing of the present utility model.
Among the figure: 1, main pipe 2, compensator locking flange 3, seal ring 4, flange bolt 5, pipeline compensator telescopic pipe 6, main pipe connecting body 7, tilted conical sealing surface 8, stepped shape projection
Embodiment
With reference to Fig. 1, the utility model comprises compensator locking flange (2), seal ring (3), flange bolt (4), lock flange (2) relative inner and the contacted corner of seal ring (3) at two that are positioned at the compensator end, tilted conical sealing surface (7) is set, at a end pipeline compensator telescopic pipe (5) is set, taper main pipe connecting body (6) is set at the other end of telescopic pipe (5) near compensator locking flange (2).In addition, inboard and at two locking flanges (2) near the lateral direction of tilted conical sealing surface (7), design a stepped shape projection (8).
It is convenient that the utility model is installed or changed, no matter where can both be stuck on the main pipe firmly, at infusion pressure 2.0MPa with interior difficult leakage, after seal ring is worn, only need tighten flange bolt (4), allow tilted conical sealing surface (7) further crush seal circle (3) inward, allow seal ring be stuck in tightly on the main pipe (1), continue the performance seal action, thus the working life of compensator prolonged, and can improve the infusion pressure in the pipe.

Claims (2)

1. pipeline compensator, it comprises compensator locking flange (2), seal ring (3), flange bolt (4), it is characterized in that: in two flange (2) relative inner that are positioned at the compensator end and the contacted corner of seal ring (3), be provided with tilted conical sealing surface (7), be provided with pipeline compensator telescopic pipe (5) at a end, be provided with taper main pipe connecting body (6) at the other end of telescopic pipe (5) near compensator locking flange (2).
2. pipeline compensator according to claim 1 is characterized in that: inboard and at two flanges (2) near the lateral direction of tilted conical sealing surface (7), be provided with a stepped shape projection (8).
