[0006] Preferably, the sealing ring has an L-shaped cross-section, and the two ends of the sealing ring cross-section are respectively provided with an outer sealing bladder and an inner sealing bladder, which are connected by an internal channel.

[0007] Preferably, a positioning pressure plate is provided on the inner side of the fixing cover. The positioning pressure plate is inserted into the inner side of the tube body and presses against one end of the silicon carbide film body. Both the fixing cover and the positioning pressure plate are provided with connecting holes.

[0008] Preferably, the positioning plate has a T-shaped cross-section, and the sealing ring is fitted on the outside of the positioning plate.

[0009] Preferably, a positioning protrusion is provided on the inner side of the tube body, and the positioning protrusion is supported on the outer side of the silicon carbide film body.

[0010] Preferably, the tube body includes an outer shell and an inner liner disposed within the outer shell, a reinforcing ring is disposed between the outer shell and the inner liner, and one end of the positioning protrusion is fixed to the reinforcing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. With the designed fixing cap and sealing ring, the silicon carbide film body is installed in the tube body during use. The fixing cap is screwed onto the tube body by threads, and the sealing ring seals the connection between the fixing cap and the tube body. This makes disassembly and assembly more convenient and ensures sealing performance after long-term use.

[0013] 2. The inner lining and positioning protrusions reinforce the tube body and facilitate the support and installation of the silicon carbide membrane body. The positioning pressure plate facilitates the positioning and installation of the fixing cover, thereby ensuring greater stability after the fixing cover and silicon carbide membrane body are installed.

[0018] 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.

[0019] Example 1: Please refer to Figs. 1-3This utility model provides a technical solution: a silicon carbide tubular membrane, including a tube body 1 and a silicon carbide membrane body 8 installed inside the tube body 1. One end of the tube body 1 is screwed with a fixing cap 2, and a sealing ring 3 is provided on the inner side of the fixing cap 2, pressing against one end of the tube body 1. The sealing ring 3 has an L-shaped cross-section, and two ends of the cross-section of the sealing ring 3 are respectively provided with a sealing outer bladder 6 and a sealing inner bladder 7, which are connected by an internal channel. During use, the fixing cap 2 pushes the sealing ring. 3 is pressed tightly against one end of the tube body 1. The sealing outer bladder 6 and the sealing inner bladder 7 work together to strengthen the seal at the connection between the tube body 1 and the fixed cover 2. A positioning pressure plate 4 is provided on the inner side of the fixed cover 2. The positioning pressure plate 4 is inserted into the inner side of the tube body 1 and pressed against one end of the silicon carbide film body 8.
