The front ends of the first lower sleeve 101 and the first upper sleeve 102 are spliced ​​into a horizontal tube shape, and the rear ends of the first lower sleeve 101 and the first upper sleeve 102 are spliced ​​with the first valve sleeve 103 and the second valve sleeve 104 into a vertical tube shape. The external valve can be referenced. Figures 1-3 The external valve flange ring is located on one side of the extension pipe, and the external valve body is the main body.

[0025] The outer sheath 200 includes a left half sheath 201 and a right half sheath 202 located outside the first lower half sheath 101 and the first upper half sheath 102, and a rear valve sheath 203 located outside the first valve sheath 103 and the second valve sheath 104.

[0026] The first lower half sheath 101, the first upper half sheath 102, the first valve sleeve 103 and the second valve sleeve 104 are connected by a snap-fit ​​assembly 300, and the first lower half sheath 101, the first upper half sheath 102 and the rear valve sleeve 203 are connected by a snap-fit ​​assembly 300.

[0027] The front ends of the left half-shroud 201 and the right half-shroud 202 are spliced ​​together to form a horizontal tube. The front ends of the left half-shroud 201 and the right half-shroud 202 are spliced ​​together with the rear valve sleeve 203 to form a vertical tube. In use, first, the aerogel felt 400 is wrapped around the outside of the valve. Then, the first lower half-shroud 101 is attached to the front flange ring of the external valve. Next, the first upper half-shroud 102 is spliced ​​and fixed to the first lower half-shroud 101. The first upper half-shroud 102 and the first lower half-shroud 101 are fitted and surrounded to the front end of the front flange ring of the external valve and the front end of the valve body. Finally, the first valve sleeve 103 is joined to the first upper half-shroud 102 and the first lower half-shroud 203 to form a vertical tube. The lower half of the sheath 101 is spliced ​​at the left rear end position. The second valve sleeve 104 is spliced ​​at the right rear end position of the first upper half sheath 102 and the first lower half sheath 101. Then, the components are connected and fixed together by the snap-fit ​​assembly 300. After completion, the left half sheath 201 and the right half sheath 202 are spliced ​​to the outside of the first upper half sheath 102 and the first lower half sheath 101. The rear left and right sides of the valve sleeve 203 are spliced ​​and connected to the first upper half sheath 102 and the first lower half sheath 101. The inner sheath 100 and the outer sheath 200 are easy to disassemble and can be reused, which is convenient for maintenance personnel to carry out later maintenance.

[0028] The distance between the inner sheath 100 and the outer sheath 200 is 2mm to 10mm, and the actual usage distance is about 5mm, leaving a margin. Sound insulation or heat insulation materials can be added according to customer needs.

[0029] It also includes an aerogel felt 400 located between the inner sheath 100 and the outer valve. The aerogel felt 400 has good thermal insulation properties. The aerogel felt 400 is an existing material and will not be described in detail here.

[0030] The buckle assembly 300 includes a hook block 301, a hinge block 302 spaced apart from the hook block 301, a flap 303 hinged to the top of the hinge block 302, a connecting ring 304 rotatably mounted on the flap 303 and cooperating with the hook block 301, a locking block 305 located in the middle of the hinge block 302, a horizontal slot 306 located on the top of the locking block 305, a horizontal hole 307 located in the middle of the flap 303 and engaged in the horizontal slot 306, and a spring 308 located between the locking block 305 and the hinge block 302.

[0031] To disassemble the buckle assembly 300, press down on the locking block 305. After rotating the locking block 305, the horizontal locking groove 306 disengages from the horizontal hole 307 in the middle of the flip plate 303. Then rotate the flip plate 303 upwards. The flip plate 303 causes the connecting ring 304 to tilt upwards, pulling the connecting ring 304 out of the hook block 301. Then, disassemble the buckle assemblies 300 on the outer sheath 200 and the inner sheath 100 in sequence.

[0032] When installation is required, such as Figures 4-10The hook block 301 is fixed at the top and bottom of the first lower half sheath 101. The hinge block 302 is located near the hook block 301 on the first upper half sheath 102. The first upper half sheath 102 is spliced ​​and attached to the first lower half sheath 101. Then the connecting ring 304 is placed inside the hook block 301. Then the flip plate 303 is rotated downward. After the flip plate 303 is attached to the hinge block 302, it will drive the connecting ring 304 to lock inside the hook block 301. During the downward rotation of the flip plate 303, the horizontal hole 307 passes through the locking block 305. The horizontal slot 306 on the locking block 305 is engaged in the horizontal hole 307 of the flip plate 303 under the action of the spring 308. The installation of the sheath is quick and convenient through the buckle assembly 300. The sheath can be reused. The installation principle of other components of the inner sheath 100 and the outer sheath 200 is the same as above, and will not be described in detail here.

[0033] The top of the locking block 305 is inclined on the side near the horizontal slot 306. When the flip plate 303 flips downward, the horizontal hole 307 of the flip plate 303 can automatically engage with the slot 306 along the inclined surface.
