Description

Technical Field

[0001] This utility model relates to the field of pipe fitting sealing technology, specifically to a quick-setting energy-saving sealing structure for liquid raw material tape in pipe fittings. Background Technology

[0002] Liquid PTFE tape, as a commonly used pipe sealing material, has advantages such as good sealing performance, aging resistance, and wide applicability. It is widely used in threaded connection sealing in water supply and drainage, gas, and industrial pipelines. In the existing technology, liquid PTFE tape is usually directly coated onto the external thread surface of the pipe fitting, and then screwed into the joint for fixation, relying on ambient temperature for natural curing.

[0003] However, this traditional sealing structure has significant drawbacks: firstly, the liquid raw material tape cures slowly, especially in low-temperature environments, where curing times can last for several hours or even longer, affecting construction efficiency; secondly, the sealing area lacks effective heat conduction and insulation structures, and fluctuations in ambient temperature or heat loss further delay the curing process. Furthermore, the cured sealing layer is prone to stress shrinkage due to temperature changes, reducing sealing stability, while heat loss also leads to energy waste. Therefore, a sealing structure that can accelerate curing and reduce heat loss is urgently needed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a fast-curing and energy-saving sealing structure for liquid raw material tape in pipe fittings, so as to solve the problems of slow curing, high energy consumption and insufficient sealing reliability of liquid raw material tape in the prior art.

[0005] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: A quick-setting energy-saving sealing structure for a pipe fitting with liquid PTFE tape includes a connector with internal threads and a pipe fitting with external threads. The internal and external threads are screwed together. The structure also includes a liquid PTFE tape sealing layer, a thermally conductive reinforcing layer, and an insulation sleeve. The liquid PTFE tape sealing layer is uniformly coated on the external thread surface of the pipe fitting body. The thermally conductive reinforcing layer tightly wraps around the outside of the connector and completely covers the liquid PTFE tape sealing layer. The insulation sleeve is detachably fitted outside the thermally conductive reinforcing layer. This detachable structure facilitates installation and maintenance. Its inner wall fits against the outer wall of the thermally conductive reinforcing layer, reducing heat loss and achieving energy-saving effects.

[0006] As a further improvement of this utility model, the thermal conductivity enhancement layer is a high thermal conductivity silicone layer.

[0007] As a further improvement of this utility model, the thickness of the thermally conductive reinforcing layer is 0.5-2mm, and its surface is provided with several axially conductive heat pipes. The axially conductive heat pipes extend along the axial direction of the pipe body, which can accelerate the transfer of ambient heat or heat of the pipeline transport medium to the sealing layer and promote the rapid curing of liquid raw material tape.

[0008] As a further improvement of this utility model, the insulation sleeve includes an inner layer of insulation cotton and an outer protective sleeve. The insulation cotton is made of flame-retardant polyurethane material, which has good heat insulation effect and flame retardancy, avoiding safety hazards. The protective sleeve is made of flexible rubber material, which plays a role in wear resistance and corrosion resistance.

[0009] As a further improvement of this utility model, the coating thickness of the liquid raw material tape sealing layer is 0.2-0.8mm, and the coating range covers the complete meshing surface of the external thread of the pipe body, ensuring full fit of the sealing surface and avoiding sealing failure due to missed coating.

[0010] The beneficial effects of this utility model are: 1. Fast curing: The thermally conductive reinforcement layer is made of high thermal conductivity silicone material, which, together with the axial heat transfer cable, can quickly transfer heat to the liquid raw material tape sealing layer. Compared with the traditional structure, the curing time is shortened by more than 60%, significantly improving construction efficiency.

[0011] 2. Energy saving: The flame-retardant polyurethane insulation cotton of the insulation jacket can effectively reduce heat loss in the sealing parts, especially suitable for pipelines transporting high-temperature media, reducing energy consumption, and avoiding the impact of low-temperature environment on the curing process.

[0012] 3. Sealing stability: The liquid raw material tape sealing layer covers the entire mating surface, and the tight wrapping of the thermally conductive reinforcement layer ensures uniform stress on the sealing layer. The insulation sleeve reduces the impact of temperature fluctuations on the sealing layer, avoids stress shrinkage, improves sealing durability, and reduces the risk of leakage.

[0013] 4. Easy to install and disassemble: The insulation sleeve has a detachable structure, which can be quickly disassembled during later maintenance or pipeline inspection without damaging the joints and pipe fittings, making it highly practical. Attached Figure Description

[0019] The thermally conductive enhancement layer 4 is a high thermal conductivity silicone layer.

[0020] The thickness of the thermally conductive reinforcing layer 4 is 0.5-2mm, and its surface is provided with several axially conductive heat pipes 41. The axially conductive heat pipes 41 extend along the axial direction of the pipe fitting 2 body, which can accelerate the transfer of ambient heat or heat of the pipeline transport medium to the sealing layer and promote the rapid curing of liquid raw material tape.

[0021] The insulation sleeve 5 includes an inner insulation cotton 51 and an outer protective sleeve 52. The insulation cotton 51 is made of flame-retardant polyurethane material, which has good heat insulation effect and flame retardancy, avoiding safety hazards.
