Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1, this embodiment provides a sealing structure for a heating device, which includes a superlattice nanometer heating element 1, an insulating sealing member 2 covering a pipe orifice of the superlattice nanometer heating element 1, a flange 3 sleeved on the periphery of the insulating sealing member 2, a sealing cover 4 sleeved on the superlattice nanometer heating element 1 and in threaded connection with a lower end of the flange 3, and a sealing ring 5 sleeved on the superlattice nanometer heating element 1 and pressed between the flange 3 and the sealing cover 4; an electrode 6 is exposed out of the middle of the insulating sealing element 2, and the lower bottom surface of the sealing cover 4 is coaxially and hermetically arranged with a mounting hole of an external mounting body.
Specifically, the cross section of the insulating sealing member 2 in this embodiment is U-shaped, and the insulating sealing member 2 and the flange 3 are fastened together. For the convenience of installation, the flange 3 and the superlattice nanometer heating element 1 are coaxially arranged, and external threads are arranged on the outer peripheral surfaces of the upper port wall and the lower port wall of the flange 3.
Further, in this embodiment, a through hole having a diameter equal to the outer diameter of the superlattice nanometer heating element 1 penetrates through the inner bottom surface of the sealing cover 4, and the through hole and the mounting hole of the external mounting body are coaxially and hermetically arranged. In order to facilitate the sealing welding of the sealing cover 4 and the mounting hole of the external mounting body, the sealing cover 4 in the embodiment is a stainless steel sleeve, and the inner circumferential surface of the sealing cover is provided with internal threads. After the flange 3 is screwed with the sealing cover 4, the upper end surface and the lower end surface of the sealing ring 5 are respectively abutted against the lower end surface of the flange 3 and the inner bottom surface of the sealing cover 4, at the moment, the sealing ring 5 is under the action of extrusion force, the inner wall of the sealing ring 5 is more stably and reliably tightly attached to the outer wall of the superlattice nanometer heating element 1, the embodiment takes the pressure-bearing water tank as an example, the sealing cover 4 and a mounting hole formed in the pressure-bearing water tank can be coaxially and hermetically welded before installation, then the heating element 1 is inserted into the mounting hole and passes through the flange 3 fastened with the heating element 1, and is screwed with the sealing cover 4, so that liquid in the pressure-bearing water tank is effectively prevented from overflowing, and meanwhile, the.
