Moreover, in low-temperature environments, the outer sheath of the cable is prone to breakage and damage. Furthermore, gaps may appear at the pipe edge connections during installation, which reduces the service life of the pipes. Therefore, a high-pressure-resistant electric heat tracing pipe is proposed. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4A high-pressure-resistant electric heat tracing pipe includes a pipe body 100, a left mounting shaft assembly 200, and a right mounting shaft assembly 300. The left mounting shaft assembly 200 includes a shaft end seal 210 disposed on the outer wall of the pipe body 100. The inner wall of the pipe body 100 is provided with an inner shaft sleeve assembly 220, and the inner wall of the inner shaft sleeve assembly 220 is provided with an inner bushing 230. The outer wall of the inner shaft sleeve assembly 220 is provided with a connecting pipe 240, and the outer wall of the connecting pipe 240 is provided with an adjuster 250. The shaft end seal 210 and the inner shaft sleeve assembly 220 are integrated devices, and there is a gap between the limiting ring 221 and the inner bushing 230, which provides installation space for the pipe body 100 during installation. The inner shaft sleeve assembly 220 includes a shaft end seal 210 disposed on the inner wall of the pipe body 100. The limiting ring 221 has a connecting post 222 installed on its inner wall. An arc-shaped mounting bracket 223 is installed at the end of the connecting post 222 furthest from the limiting ring 221. When the expansion ring 324 slides within the tube body 100, the end of the shaft 321 can directly contact the arc-shaped mounting bracket 223 during the sliding process, effectively preventing the shaft 321 from directly contacting the limiting ring 221. The right mounting shaft assembly 300 includes a shaft end connecting sleeve 310 disposed on the outer wall of the tube body 100. A connecting pipe 340 is installed on the outer wall of the shaft end connecting sleeve 310, and an adjuster 350 is installed on the inner wall of the connecting pipe 340. A limiting shaft sleeve 330 is installed on the outer wall of the shaft end connecting sleeve 310, and the inner wall of the limiting shaft sleeve 330... An inner output shaft assembly 320 is provided, wherein the inner bushing assembly 220 and the shaft end connecting sleeve 310 are both made of rubber material, which effectively improves the connection stability with the tube body 100 during connection and also increases the contact area with the tube body 100 during connection. The inner output shaft assembly 320 includes a shaft 321 disposed on the inner wall of the limiting bushing 330. The outer wall of the shaft 321 is provided with a first sealing ring 322 and a second sealing ring 323. An extension ring 324 is provided at the end of the shaft 321 away from the first sealing ring 322. By providing the first sealing ring 322 and the second sealing ring 323 on the outer wall of the shaft 321, the shaft 321 can pass through the first sealing ring 322 and the second sealing ring 323 during movement. The direct contact between the second 323 and the limiting sleeve 330 effectively improves the sealing performance of the equipment. Connecting pipe 240 and connecting pipe 340 are symmetrically distributed on the outer wall of the pipe body 100, and they are interconnected. This allows the left mounting shaft assembly 200, after being connected to the right mounting shaft assembly 300, to adjust the pressure balance within the pipe body 100 by adjusting regulator 250 and regulator 350. The shaft end seal 210 and shaft end connecting sleeve 310 are symmetrically distributed on both sides of the outer wall of the pipe body 100, ensuring the sealing performance of the pipe body 100. The shaft 321 is slidably connected to the limiting sleeve 330, and both sealing rings 322 and 323 are made of natural rubber.The expansion ring 324 and the shaft 321 are integrated, and the diameter of the expansion ring 324 is the same as the diameter of the inner wall of the tube body 100. This allows the expansion ring 324 to fit snugly against the inner wall of the tube body 100 during operation, effectively improving the connection stability and preventing the tube body 100 from easily detaching during installation. The tube body 100 is primarily made of heat-resistant PVC material, which enhances its heat resistance during operation and extends its service life.

[0023] Working principle: When the equipment is needed, the worker aligns and installs the shaft end seal 210 with the shaft end connecting sleeve 310 and the pipe body 100. After installation, the worker turns the regulator 1 250 and regulator 2 350 respectively, and connects the connecting pipe 1 240 to the external connector.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
