[0019] like Figure 1 The overhead gas pipeline protection sleeve shown includes: a sleeve 4, a sponge filling layer 3, a rubber ring 5 and a clamp 6. Anti-corrosion paint is applied to the outside of the gas pipeline 1 as an anti-corrosion layer 2. The sponge filling layer 3 is sleeved on the outside of the gas pipeline 1, and the sponge filling layer 3 is composed of a sponge tape wrapped around the outer layer of the gas pipeline 1, which is used to fill the gap between the sleeve 4 and the gas pipeline 1 to prevent the sleeve 4 from shaking. In order to ensure the filling effect, the thickness of the sponge filling layer 3 is greater than the distance between the gas pipeline 1 and the sleeve 4. After the sleeve 4 is installed, the sponge filling layer 3 is squeezed to completely fill the gap.
[0020] The sleeve 4 is a circular structure with a diameter larger than the gas pipeline 1, including a left sleeve 4 and a right sleeve 4 matched with the left sleeve 4, and the left sleeve 4 and the right sleeve 4 are sleeved outside the sponge filling layer 3 and bonded by glue. The sleeve 4 is provided with a plurality of clamps 6 for fixing the sleeve 4, and the clamps 6 are fixed at the top and tail ends of the sleeve 4. In order to further improve the fixing effect and prevent the middle part of the sleeve 4 from being damaged by force, a plurality of clamps 6 can also be provided in the middle part of the sleeve 4. The clamps 6 on the sleeve 4 are arranged at equal distances, and the number is increased or decreased according to the length of the sleeve 4.
[0021] The clamp 6 at the end of the sleeve 4 fixes the sleeve 4 and seals both ends of the sleeve 4. In order to further prevent rainwater from entering the sleeve 4 from the gap, first, when the sponge tape is wound to form the sponge filling layer 3, the installation position of the rubber ring 5 is reserved at the two ends of the sleeve 4. The rubber ring 5 is sleeved on the outside of the gas pipeline 1 and in close contact with the sleeve 4. The rubber ring 5 is pressed between the gas pipeline 1 and the sleeve 4 to form a tight seal between them, thereby preventing water from leaking and preventing rainwater from penetrating into the sleeve.
[0022] Secondly, polyurethane foaming agent can be filled between the upper side of the clamp 6 at the top end of the sleeve 4 and the gas pipeline 1, and polyurethane foaming agent can be filled between the lower side of the clamp 6 at the tail end of the sleeve 4 and the gas pipeline 1 to prevent the accumulated water from corroding the rubber ring 5 and causing leakage. High-quality polyurethane foaming agent meets relevant environmental protection standards and can be used in large quantities with almost no adverse effects on the human body and the environment.
[0023] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
