Description

Technical Field

[0001] The utility model belongs to the technical field of sealing devices, in particular to a pure water tank sealing device. Background Art

[0002] Pure water equipment mainly uses reverse osmosis membrane technology. Its working principle is to apply a certain pressure to water, so that water molecules and ionized mineral elements pass through the reverse osmosis membrane, while most inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in the water cannot pass through the reverse osmosis membrane, so that the permeated pure water and the impermeable concentrated water are strictly separated; the pore size on the reverse osmosis membrane is only 0.0001 micron, while the diameter of the virus is generally 0.02-0.4 micron, and the diameter of ordinary bacteria is 0.4-1 micron.

[0003] When current pure water equipment is working, it is necessary to use water pipes to transport raw water to the inside of the pure water equipment for purification. The water pipes on the existing pure water equipment are all sealed with flanges, which are usually fixed with screws. If a water leakage problem occurs in the later stage, the screws need to be tightened to remove the flange, which is very troublesome. The screws are prone to rust over time, which increases the difficulty of disassembly. Failure to quickly inspect the sealing device will affect subsequent production. Utility Model Content

[0006] Furthermore, the sealing ring is arranged closely against the sealing circular groove, the sealing circular ring plate is located between the sealing ring and the sealing circular groove, the gap between the sealing ring and the sealing circular groove is consistent with the sealing circular ring plate, and the three are tightly connected.

[0007] Furthermore, the springs are both located inside the first fixing groove and the second fixing groove, the springs are both fixedly connected to the first fixing groove and the second fixing groove, and the length of the springs is smaller than the length of the first fixing groove and the second fixing groove.

[0008] Furthermore, the sum of the lengths of the fixing block and the limiting block is the same as the lengths of the first fixing slot and the second fixing slot, and the fixing block and the limiting block are both movably connected to the first fixing slot and the second fixing slot.

[0013] Beneficial effects: The utility model has reasonable design and has the following beneficial effects:

[0014] 1. It is necessary to take out the card plates on the four fixing devices from the card slots, so that the limit plate can be separated from the side of the fixing block. The pressure fixing block without the limit plate will be separated from the first fixing slot and the second fixing slot due to the action of the spring. Through the action of the limit block and the limit slot, the fixing block will stay in the moving slot. Then the four fixing devices can be taken away from the sides of the first sealing plate and the second sealing plate, so that the two sealing plates can be separated for maintenance. The fixing device can be disassembled by simply taking the card plate out of the card slot, which is very convenient to operate.

[0015] 2. The sealing ring can be replaced after long-term use to prevent aging from affecting the sealing effect. The cooperation between the sealing ring and the sealing ring plate can make the sealing effect between the first connecting pipe and the second connecting pipe better, so that the raw water can be better transported to the water purifier without leakage.

The clamping plate 89 is movably connected inside the clamping groove 84. A connecting block 88 is provided on the side of the clamping plate 89 away from the fixed plate 81. A limiting plate 87 is provided on the end of the connecting block 88 close to the connecting plate 82. Limiting blocks 810 are provided on both sides of the end of the fixed block 85 close to the spring 86. Limiting grooves 811 are provided on both ends of the movable groove 83 close to the spring 86. A first fixed groove 9 is provided between the fixed block 85 and the first sealing plate 3, and a second fixed groove 10 is provided between the fixed block 85 and the second sealing plate 4.

[0025] Among them, the sealing ring 7 is arranged closely against the sealing circular groove 6, the sealing circular ring plate 5 is located between the sealing ring 7 and the sealing circular groove 6, the gap between the sealing ring 7 and the sealing circular groove 6 coincides with the sealing circular ring plate 5 and the three are tightly connected; the sealing ring 7 can be replaced after long-term use in the later stage to prevent aging from affecting the sealing effect. Through the cooperation between the sealing ring 7 and the sealing circular ring plate 6, the sealing effect between the first connecting pipe 1 and the second connecting pipe 2 can be better, so that the raw water can be better transported to the pure water machine without leakage.

[0026] The springs 86 are all located inside the first fixed groove 9 and the second fixed groove 10, and the springs 86 are all fixedly connected to the first fixed groove 9 and the second fixed groove 10. The length of the spring 86 is less than the length of the first fixed groove 9 and the second fixed groove 10; the sum of the lengths of the fixed block 85 and the limiting block 810 is the same as the length of the first fixed groove 9 and the second fixed groove 10, and the fixed block 85 and the limiting block are all movably connected to the first fixed groove 9 and the second fixed groove 10; the movable grooves 83 are all located on the sides of the first fixed groove 9 and the second fixed groove 10 and the lengths and heights of the three are the same; the spring 86 is in a compressed state when the fixing device 8 fixes the two sealing plates.

[0027] The sum of the widths of the first sealing plate 3 and the second sealing plate 4 is the same as the length of the fixing plate 81 ; this allows the fixing device 8 to better fix the two sealing plates.

[0028] The limiting plates 87 are all located on the side of the moving groove 83; the clamping plates 89 are all matched with the clamping groove 84 and the two are movably connected. The first sealing plate 3 and the second sealing plate 4 have the same length, width and height and are movably connected; the limiting plates 87 are located on the side of the fixed block 85 when the fixing device 8 fixes the two sealing plates, and the fixed block 85 is limited and fixed so that the fixed block 85 is always located inside the moving groove 83, the first fixed groove 9 and the second fixed groove 10. The position of the limiting plates 87 can be adjusted by moving the position of the clamping plates 89, thereby adjusting the position of the fixed block 85.

[0029] Working principle: When the sealing device needs to be repaired during use, the card plates 89 on the four fixing devices 8 need to be taken out from the card slots 84, so that the limit plate 87 is detached from the side of the fixing block 85. The pressure fixing block 85 without the limit plate 87 will be detached from the first fixing slot 9 and the second fixing slot 10 due to the action of the spring 86. Through the action of the limit block 810 and the limit slot 811, the fixing block 85 will stay in the movable slot 83. Then the four fixing devices 8 can be removed from the sides of the first sealing plate 3 and the second sealing plate 4. In this way, the two sealing plates can be separated for repair to see if the sealing ring 7 needs to be replaced.
