Problems solved by technology
A high-reliable electric heating pipe sealing structure and method are disclosed. A lead rod is arranged in an electric heating tube body. A space between the lead rod and the tube body is filled withmagnesium oxide powders. An insulation sealing device is disposed at the sealing port of the electric heating tube body and is composed of an upper opening, a middle channel, a lower channel, and a lower opening. The lead rod penetrates through the middle channel of a sealing port device. A sealant is arranged between the insulation sealing device and the electric heating pipe body. The outer diameter of the upper part of the insulation sealing device is larger than the diameter of the outer wall of the sealing port of the electric heating pipe body, and the outer diameter of the lower part of the insulation sealing device is smaller than the diameter of the inner wall of the electric heating pipe body. The diameter of the upper opening gradually decreases toward the middle of the sealingport device. The diameter of the lower channel gradually decreases toward the middle of the insulation sealing device. The lower opening is located below the lower channel. The diameter of the loweropening gradually decreases toward the lower channel. The smallest diameter of the lower opening is equal to the largest diameter of the lower channel. The high-reliable electric heating pipe sealingstructure has the advantages of good bonding during the curing process of the sealant and improving the insulation withstand voltage.
