[0021] The reverse osmosis membrane shell sealing structure with end cover handle according to the present application will be described in more detail below with reference to the accompanying drawings, in which the preferred embodiments of the present application are shown, it should be understood that the present application described herein can be modified by those skilled in the art, and the advantageous effects of the present application can still be achieved. Therefore, the following description should be understood as a broad knowledge for those skilled in the art, and not as a limitation of the present application.

[0022] The present application will be described in more detail in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present application will be more apparent according to the following description. It should be noted that the drawings are very simplified and all use non-precise proportions, only to facilitate, clear and assist the purpose of illustrating the embodiments of the present application.

[0023] As shown in Figs. 1-2 The reverse osmosis membrane shell sealing structure with end cover handle according to the present application comprises a membrane shell 1, an end cover assembly arranged in the internal space of the membrane shell 1, and a water production channel 6 connected with the end cover assembly, and the end cover assembly is connected with the membrane shell 1.

[0024] The end cover assembly comprises an end cover pressure plate 5 and an end cover handle 2, the end cover pressure plate 5 is connected with the membrane shell 1, the water production channel 6 penetrates through the end cover pressure plate 5, and the water outlet of the water production channel 6 is located on one side of the end cover pressure plate 5, so as to improve the efficiency of water flow and reduce pressure loss. The end cover handle 2 is connected with the water outlet through a fastener, so as to facilitate disassembling the end cover assembly through the end cover handle and the fastener.

[0025] In the present embodiment, the front surface of the end cover handle is I-shaped, a groove part is arranged on the back surface of the end cover handle, and the groove part faces the end cover pressure plate 5, so that the operator can naturally stretch into the groove to form stable grip, effectively prevent slipping, and improve the safety of disassembly operation.

[0026] In the present embodiment, the end cover assembly further comprises an end cover sealing plate 3, a U-shaped end cover sealing ring 4, and a pressure plate stop ring 7.

[0027] The end cover sealing plate 3 is arranged on the other side of the end cover pressure plate 5, connected with the membrane shell 1, and the middle part of the end cover sealing plate 3 penetrates through the end cover pressure plate 5.

[0028] One end of the U-shaped end cover sealing ring 4 is connected with the end cover sealing plate 3 and located on the inner wall of the membrane shell 1, and the U-shaped opening faces the inside of the membrane shell 1. When there is no medium pressure or the medium pressure is low in the inside of the membrane shell 1, the U-shaped end cover sealing ring 4 maintains a certain shape due to its elasticity. When the medium pressure increases, due to the U-shaped structure of the U-shaped end cover sealing ring 4, the U-shaped end cover sealing ring 4 is pushed by the medium pressure to contact the end cover sealing plate 3, so that the U-shaped end cover sealing ring 4 is tightly attached to the membrane shell 1 and the end cover sealing plate 3. The greater the medium pressure, the greater the attachment force of the U-shaped end cover sealing ring 4 to the inner wall of the membrane shell 1 and the circumference of the end cover sealing plate 3, so that the U-shaped end cover sealing ring 4 is more tightly attached to the inner wall of the membrane shell 1, that is, the U-shaped end cover sealing ring 4 is tightly attached to the inner wall of the membrane shell 1 and the circumference of the end cover sealing plate 3 under the action of the medium pressure to form a self-sealing. The self-sealing can automatically adapt to pressure changes and provide more stable sealing effect.

[0029] In addition, since the U-shaped end cover sealing ring 4 is annular and has a U-shaped cross section in the radial direction, Fig. 1 only the upper half of the U-shaped end cover sealing ring 4 is shown, Fig. 1 the lower half of the U-shaped end cover sealing ring 4 is not shown.

[0030] In addition, the U-shaped end cover sealing ring 4 is made of elastic material, and common sealing materials such as rubber can be selected. Due to the elasticity and toughness of the U-shaped sealing ring 4, the U-shaped end cover sealing ring 4 can be tightly attached after compression, thereby providing excellent sealing effect.

[0031] In an embodiment, the inner wall of the membrane shell 1 is provided with a groove, the U-shaped end cover sealing ring 4 is arranged in the groove, and the end of the U-shaped end cover sealing ring 4 connected with the end cover sealing plate 3 is located outside the groove and is tightly connected with the end cover sealing plate 3. The U-shaped sealing ring 4 is fixed in the groove, and when high pressure is running, the self-sealing function of the U-shaped sealing ring 4 is combined with the limiting effect of the groove to effectively prevent medium leakage, thereby improving the sealing effect.

[0032] The shape of the groove matches the shape of the U-shaped end cover sealing ring 4, so that the U-shaped end cover sealing ring 4 can better contact the inner wall of the membrane shell 1, thereby being more tightly attached under the action of pressure, improving the sealing effect and reducing the possibility of leakage.

[0033] In the embodiment, the pressure plate retaining ring 7 is arranged on the other side of the end cover pressure plate 5 and located in the membrane shell 1. The pressure plate retaining ring 7 is used to fix the end cover pressure plate 5, preventing the end cover pressure plate 5 from being displaced or falling off under pressure.

[0034] In the embodiment, the reverse osmosis membrane shell sealing structure further comprises an adapter 8.

[0035] The adapter 8 is sleeved on the product water channel 6, connecting the components together to form a complete reverse osmosis membrane structure. The end cover sealing plate 3 is sleeved on the adapter 8, which can ensure the sealing between the product water channel 6 and the external system, preventing leakage.

[0036] In a specific embodiment, the fastener is a fastening nut 9. The part of the end cover sealing plate 3 passing through and located on the other side of the end cover pressure plate 5 is provided with external threads, and the fastening nut 9 is engaged with the external threads, used to fix the end cover pressure plate 5 and the end cover sealing plate 3, improving the sealing performance of the end cover assembly, thereby preventing water or other liquids from leaking between the end cover pressure plate 5 and the end cover sealing plate 3.

[0037] In summary, the end cover handle is arranged at the product water outlet of the product water channel, so that the end cover assembly can be disassembled through the end cover handle and the fastener, avoiding the deformation or fracture of the end cover assembly caused by the traditional disassembly method, effectively prolonging the service life of the equipment. The design of the I-shaped end cover handle conforms to the principle of ergonomics, so that the fingers can naturally extend into the groove to form stable gripping, effectively preventing slipping and improving the safety of disassembly operation.

[0038] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Therefore, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
