Double-sealing filling sleeve compensator

Abstract

The invention discloses a double-sealing filling sleeve compensator, and relates to the field of compensators. Not less than three filling nozzles are annularly distributed in the outer walls of a lower barrel body and an upper barrel body separately; sealing fillers are filled at the inner sides of the lower barrel body and the upper barrel body, and between a guide bearing bush and a gland ringseparately; and a humidity sensor is arranged at one side close to a water drainage port, of the inner wall of the upper barrel body. According to the double-sealing filling sleeve compensator, a double-layer sealing structure is adopted, so that the sealing effect of the product in a working process is greatly improved; the humidity sensor is arranged between the two layers of sealing, whether aleakage phenomenon of equipment occurs or not can be directly viewed, and once the leakage phenomenon is found, a sealing agent can be injected into the filling nozzles in time by virtue of a high-pressure agent injection gun, so that the hidden danger of leakage is eliminated in time, high safety is achieved, and meanwhile, the loss brought by the stop maintenance of the equipment is effectivelyavoided; and high-concentration flexible graphite packing and flexible graphite powder are adopted as a sealing material, and the sealing agent is expanded at a high temperature, so that the sealing effect is greatly improved.

Description

technical field [0001] The invention relates to the field of compensators, in particular to a double-seal filling type sleeve compensator. Background technique [0002] The injection-filled sleeve compensator is a compensator that is directly installed in any pipeline that transports non-corrosive one-way or multi-way fluids. It is mainly composed of a sleeve (core tube), a shell, and a sealing material. It is used for Compensate for the axial expansion and contraction of the pipeline and the axial rotation at any angle. The sliding surface of the injection-filled sleeve compensator is specially treated, and it has good corrosion resistance in the environment of salt water and salt solution, which is more than 50 times higher than that of austenitic stainless steel. At the same time, when the sealing effect is weakened due to wear after many years, the sealant can be injected into the stuffing chamber under normal working conditions to enhance the sealing performance, which ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-seal injection-filling sleeve compensator to solve the complex structure, single seal, cumbersome production process and extremely low processing efficiency proposed in the above background technology. With a single-layer seal, many problems will arise once leakage occurs during the work process. If the medium is toxic and harmful substances, leakage may endanger the safety of the staff.
