[0022] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0023] refer to Figures 1 to 10The present embodiment provides a double-layer noise reduction and thermal insulation pipe, comprising a pipe body 1, a soft porcelain layer 2 arranged on the outside of the pipe body 1, a glass wool layer 3 arranged on the outside of the soft magnetic thermal insulation layer, a rock wool interlayer 4 arranged on the outside of the glass wool layer 3, a reinforcement mesh 5 arranged between the glass wool layer 3 and the rock wool interlayer 4, an outer layer 6 arranged on the outside of the rock wool interlayer 4, a U-shaped base 7 arranged at the bottom of the outer layer 6, and a U-shaped insert 8 connected to the U-shaped base 7, wherein a connecting nut 9 is screwed on the bottom of the U-shaped insert 8; the soft porcelain layer 2 is made of modified clay (MCM) as the main raw material, and is formed, baked, and irradiated and cross-linked using a special temperature-controlled molding system; the glass wool layer 3 is a felt blanket made of glass fiber, and the rock wool interlayer is made of inorganic fiber and other materials; the soft porcelain layer, glass wool layer, and rock wool interlayer are all products available on the market, and they are existing materials and will not be described in detail here.

[0024] During use, the soft porcelain layer is made of modified clay as the main raw material. It has excellent thermal insulation performance and is flexible enough to fit the outside of the pipe body. The glass wool layer has good sound absorption and noise reduction performance, which can reduce the noise inside the pipe body. The rock wool interlayer is on the outside of the glass wool layer. The glass wool layer has better sound insulation and fire prevention effects. The glass wool layer has low cost and can be laid in advance. Then the rock wool interlayer is laid on the outer layer of the glass wool layer, which can reduce the dust and some glass fiber overflow of the glass wool layer, and further improve the sound insulation effect. The reinforcement net can make the glass wool layer firmly fixed to the outer layer of the soft porcelain layer, and at the same time prevent the glass wool layer from long-term vibration and position displacement. The outer layer is wrapped with a rock wool interlayer, which can protect the rock wool interlayer and prevent the rock wool interlayer from aging or being damaged by foreign objects. After the pipe is inserted into the U-shaped base through the U-shaped insert, the bottom of the U-shaped insert is screwed and fixed by a connecting nut. The soft porcelain layer, glass wool layer and rock wool interlayer on the outside of the pipe fit more tightly and are not easy to loosen and fall off to produce gaps, greatly improving the service life and noise reduction performance.

[0025] One end of the reinforcement net 5 is provided with a disassembly device 10, and the disassembly device 10 includes a first spacer 101, a second spacer 102 spaced apart from the first spacer 101, a first adjusting bolt 103 provided on both sides of the second spacer 102 and the second spacer 102, an adjusting nut 104 matched with the first adjusting bolt 103, a first protruding rod 105 fixed on one side of the first spacer 101, a second protruding rod 106 fixed on one side of the second spacer 102, and a U-shaped card seat 100 rotatably connected to the first protruding rod 105 and the second protruding rod 106. 7. An opening 108 is provided in the middle of the U-shaped base 107, and a locking bolt 109 is provided in the middle of the U-shaped base 107. A rubber pad 111 is provided on the inner side of the U-shaped base 107. The rubber pad 111 protects one side of the iron wire to prevent the locking bolt 109 from squeezing the reinforcement mesh 5. Since the U-shaped base 107 is also made of metal, the problem of deformation and damage caused by the built-in iron wire of the reinforcement mesh 5 after compression is solved. The surface of the U-shaped base 7 has an electroplating layer, which is beneficial to improving the corrosion resistance and wear resistance of the U-shaped base 7 and extending the service life of the U-shaped base 7.

[0026] When the U-shaped bracket is fixed, the first fixing bolt is inserted into the fixing nut, and the first fixing bolt is inserted into the fixing nut to reduce the spacing between the first and second fixing plates, thereby reducing the spacing between the left and right sides of the reinforcement net. Compared with the existing reinforcement net fixing method, the reinforcement net is tightened manually and then fixed with wire. During long-term use, the wire is easy to loosen, and two people are required to cooperate to fix the wire mesh during the tightening process of the reinforcement net. This structure has good fixation, is not easy to fail after long-term use, and can be installed by one person.

[0027] The U-shaped holder 107 is provided with a fastener 110 for adjusting the width of the opening 108. After the locking bolt 109 is tightened and inserted into the U-shaped holder 107, the fastener 110 is tightened to avoid the disadvantage that the opening 108 of the U-shaped holder 107 is widened under tension on the left and right sides of the reinforcement net 5, and the locking bolt 109 fails and falls off.

[0028] The surface of the adjusting nut 104 is provided with a plurality of arc-shaped protrusions 112 , which are in the shape of arc lines. When the adjusting nut 104 is tightened, the arc-shaped protrusions 112 will contact the second spacer 102 , increasing the friction during contact and preventing the adjusting nut 104 from loosening.
