Composite sleeve compensator with warning device and intelligent management system thereof

Abstract

The invention relates to a composite sleeve compensator with a warning device and an intelligent management system thereof. The composite sleeve compensator with the warning device comprises core tubes, corrugated pipes and a flow guide pipe, wherein the flow guide pipe is arranged in an inner cavity formed in the part from the left core tube to the right core tube; an outer sleeve pipe is arranged on the peripheries of the left corrugated pipe and the right corrugated pipe; the left end of the outer sleeve pipe is connected with the left core tube; the right end of the outer sleeve pipe is connected with the right core tube through a sealing device; the sealing device comprises a packing ring, a gland packing and a packing gland flange; the management system comprises a plurality of compensators, a signal transmission device and a central control unit; and all the compensators are in circuit connection with the signal transmission device and the central control unit. According to thecomposite sleeve compensator with the warning device and the intelligent management system thereof, the compensator is improved in sealing performance and not liable to leakage, and can maintain reliable sealing for a long time; besides, the service life is long, the maintenance cost is low, the operation is safe and reliable, and meanwhile the real-time management and safety monitoring level of the pipeline is greatly improved.

Description

technical field [0001] The invention relates to the technical field of pipeline compensators, in particular to a composite sleeve compensator equipped with an alarm device and an intelligent management system thereof. Background technique [0002] At present, when the heat pipe network transports high-temperature media such as hot water and steam, the bellows sleeve compensator is generally used to compensate the displacement of the pipe due to the expansion and contraction of the pipe due to the influence of the temperature of the medium. Because the displacement of the compensating pipe is compensated by the expansion and contraction of the bellows, the compensation capacity of the sleeve compensator is limited by the structure. The inner wall of the compensator bears the pressure of the medium, and the sealing packing cannot maintain a good sealing state for a long time, which is prone to leakage. [0003] Most bellows compensators work in the internal pressure type. Afte...

AI Technical Summary

Problems solved by technology

When the pipe expands or contracts due to thermal expansion and cold contraction, the bellows will be subjected to stretching or compression force, and the pressure on the inner wall of the bellows will easily cause the compensator to twist

During long-term use, due to the large amount of expansion and contraction produced by the heating pipe and the large wave number of the bellows, the bellows of the compensator are prone to leakage due to fatigue. Once the internal pressure bellows leaks, the entire compensator will fail

Therefore, it is necessary to maintain or replace the pipeline compensator regularly, resulting in a short service life of the compensator, a large workload of maintenance and replacement, and high cost

Sometimes due to failure to detect leaks and failed compensators in time, safety production accidents occur
