Abstract
The invention relates to a maintenance-free self-regulation compensator which comprises a connecting pipe, a guide cylinder, an outer sheath, a corrugated pipe and a long connecting pipe. The corrugated pipe is connected with the inner surface of the outer sheath, an end plate is connected with a sealing packing device, the device comprises a guide ring, a sealing ring and a pressure plate I, the guide ring is fixedly connected with the end plate, the sealing ring is arranged in a sealing cavity formed by the guide ring and the long connecting pipe, a bolt with a nut is arranged between the pressure plate I and the end plate, a spring is arranged between the nut and the pressure plate I, a convex ring is arranged at a position, which is in contact with the sealing ring, on the pressure plate I, a guide nozzle is arranged at the convex ring, and the pressure plate enables the convex ring to compress the sealing ring via the bolt and the spring. The maintenance-free self-regulation compensator has the advantages that owing to a spring and bolt sealing structure capable of automatically regulating the sealing pressure, the self-regulation sealing structure of the compensator can effectively block media even if the corrugated pipe leaks due to fatigue in a usage procedure, so that leakage of the integral compensator is prevented; and sealing packing can be injected via the guide nozzle, the sealing performance of the compensator is strengthened, and accordingly the compensator is maintenance-free.
Description
Technical field
The present invention relates to the pipeline extension expansion compensation device, especially a kind of non-maintaining self-regulation compensator that adopts bellows and the automatic regulating sealing pressure of spring bolt.
Background technique
At present, all need segmentation that some compensators for the compensation pipeline extension are installed in existing heat supply pipeline, particularly be embedded in underground length for delivery of high temperature, high-pressure medium apart from heat supply pipeline, the wall thickness of compensator is large, intensity is higher.In using process, the extending amount that produces due to heat supply pipeline is larger, compensator bellows wave number is more, the bellows of compensator easily local leakage occurs because of fatigue, therefore need periodic maintenance or change compensator, cause the working life of compensator shorter, maintenance and the workload of changing are large, and cost is higher.
Summary of the invention
For the deficiency of above existing compensator, the purpose of this invention is to provide a kind of difficult leakage, long service life, adopt the non-maintaining self-regulation compensator of bellows and the automatic regulating sealing pressure of spring bolt.
The objective of the invention is by realizing by the following technical solutions:
non-maintaining self-regulation compensator, comprise adapter, guide shell, oversheath, bellows and long pipe, the internal surface of described adapter is connected with guide shell, the outer surface of taking over is fixedly connected with oversheath by ring flat-plate, described bellows-sheathed is located between oversheath and long pipe and is connected with long pipe with oversheath respectively, described guide shell extend in long pipe, one end of described bellows is fixedly connected with guide plate by end ring, guide plate is fixedly connected with near an end of taking over long pipe, the other end of described bellows is fixedly connected with the internal surface of oversheath by end plate, described end plate is connected with sealing packing device,
Described sealing packing device comprises guide ring, seal ring, pressing plate I, described guide ring is fixedly connected with end plate, described seal ring is located in the Seal cage of guide ring and end plate and long pipe outer surface formation, be provided with nut bolt between described pressing plate I and end plate, be provided with spring between described nut and pressing plate I, the position that contacts with seal ring on the pressing plate I is provided with bulge loop, and the pressing plate I makes described bulge loop press seal circle by bolt and spring.
As the preferred technical solution of the present invention, the bulge loop position of described pressing plate I is provided with the guide mouth, and the guide mouth is communicated with the Seal cage at described seal ring place.
As the preferred technical solution of the present invention, be provided with fixed plate between the outer surface of described pressing plate I and described long pipe, fixed plate is fixedly connected with the outer surface of long pipe.
The invention has the beneficial effects as follows: with respect to prior art, compensator of the present invention adopts the spring bolt sealing configuration of bellows and automatic regulating sealing pressure, even in using process, the bellows of compensator local leakage occurs because of fatigue, the self-regulation sealing configuration of compensator can effectively stop medium, makes compensator can not occur on the whole leaking.The present invention can also inject stuffing box packing by the guide mouth, strengthens the sealability of compensator, keeps for a long time reliable sealing and normal use of compensator, thereby realizes non-maintaining purpose.It is low, safe and reliable that the present invention is difficult for leakage, long service life, maintenance cost.
