[0002] A fiberglass membrane housing is a membrane housing made of glass fiber reinforced plastic (fiberglass) and is used to package and protect reverse osmosis (RO) membrane elements. It has the characteristics of high strength, light weight, corrosion resistance and wear resistance, and can effectively extend the service life of the RO system. In some applications, the sealing performance of the membrane housing is crucial because it directly affects the filtration effect of the system and the water quality safety. The design of a highly-sealed membrane housing with an embedded ring can provide greater installation flexibility and simplicity while ensuring a tight seal, reduce maintenance costs and time, and ensure long-term stable operation.

The sealing component is used for further sealing the fiberglass membrane housing. A sealing cover 11 is arranged inside the sealing plate 7. The sealing component includes a telescopic rod 14. One end of the telescopic rod 14 is fixedly connected to the inside of the baffle 12. A spring 15 is sleeved on the outer wall of the telescopic rod 14. One end of the spring 15 is fixedly connected to the inner wall of the baffle 12. The other end of the spring 15 is fixedly connected with a sealing ring 16. One side of the outer wall of the sealing ring 16 is slidably connected to the inside of the baffle 12. The other end of the sealing ring 16 is attached to the outer wall of the sealing plate 7;

[0027] Specifically, first, a certain number of membrane elements are placed inside the cylinder body 17. Then, water is passed into the interior of the cylinder body 17 through the water inlet pipe 2 for water treatment. During this process, first, the thrust ring 4 bears the axial force to protect the rear seal and enhance stability. Then, the adapter 5 can be connected to pipes of different sizes. Next, the sealing plate 7 and the bearing plate 8 on its outer wall bear the compressive force. At the same time, the sealing plate 7 can also cooperate with the sealing insertion ring 9 on its outer wall for sealing treatment. Finally, a baffle 12 is attached to one side of the outer wall of the sealing plate 7, and the sealing plate 7 and the baffle 12 are connected and fixed by fixing bolts 13.
