Description

Technical Field

[0001] The utility model relates to the technical field of economizers, in particular to a flexible sealing sleeve for economizers. Background Art

[0002] Economizer is a device installed at the lower part of the flue at the rear of the boiler to recover the waste heat of the exhaust gas. It heats the boiler feed water into a heating surface of saturated water under the drum pressure. Since it absorbs the heat of the high-temperature flue gas, it reduces the exhaust temperature of the flue gas, saves energy and improves efficiency, so it is called an economizer. When the economizer is in use, a flexible sealing sleeve is required at the pipe connection position, so a flexible sealing sleeve for an economizer is needed.

[0003] The existing flexible sealing sleeve for economizer is not convenient for improving the corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance of the entire sealing sleeve during operation, and it is not convenient to find the position of the sealing sleeve during inspection. Therefore, a flexible sealing sleeve for economizer is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a flexible sealing sleeve for economizer to solve the problem that the existing flexible sealing sleeve for economizer is not convenient to improve the corrosion resistance, sealing, high lubrication and non-stickiness, electrical insulation and good anti-aging resistance of the entire sealing sleeve during use, and it is not convenient to find the position of the sealing sleeve during inspection.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a flexible sealing sleeve for economizer, comprising a sealing sleeve, the inner wall of which is provided with a threaded groove, the upper end of which is provided with an engaging groove, and the upper end of which is provided with a luminous closed ring.

[0006] Preferably, the sealing sleeve is made of polytetrafluoroethylene material, and the polytetrafluoroethylene material of the sealing sleeve is a flexible material.

[0007] Preferably, the upper end of the sealing sleeve is of slotted design, and the sealing sleeve fits tightly with the luminous closed ring.

[0008] Preferably, the luminous closed loop is a "T"-shaped structure, and the luminous closed loop is made by adding fluorescent material.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model provides a sealing sleeve made of polytetrafluoroethylene material, which makes the entire sealing sleeve have excellent chemical stability. At the same time, when the sealing sleeve is used, the corrosion resistance, sealing performance, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance of the entire sealing sleeve are improved;

[0011] 2. The utility model provides a sealing sleeve and a luminous closed ring, which are fused into a whole through processing. When the sealing sleeve is in use, the luminous closed ring made of fluorescent material can emit light, so that the position of the sealing sleeve can be marked during inspection.
