The plugging structure of the other end makes the water inlet flow channel formation concentrated water side water inlet flow channel of opposite side, and raw water is from raw water side water inlet flow channel stream
Enter, concentrated water flows out from concentrated water side water inlet flow channel, the water in the water inlet flow channel of raw water side enters concentrated water side water inlet flow channel by passage, makes
The water inlet of raw water and the delivery port of concentrated water are in the side of reverse-osmosis membrane element.Because raw water needs to enter from side inlet,
It is flowed into close to the position of central tube, is then flowed out again from side from the position close to central tube, the distance that raw water is flowed through is big
Cause is twice in reverse-osmosis membrane element of the prior art, this thereby necessarily increases raw water stopped in reverse-osmosis membrane element when
Between, raw water is permeated as much as possible for pure water, improve the rate of recovery of raw water.
The plugging structure makes water in production water flow passage to enter from inlet opening 6 in central tube 7 and then from central tube 7
End outflow.
In order to further make as much as possible raw water pass through from above-mentioned passage, in the outer of the reverse osmosis membrane group wound
Side is provided with exterior seal ring 4, and position of the exterior seal ring 4 with the first adhesive waterproof tape 22 on axial location is corresponding, external seal
Circle 4 has sealing function, and (exterior seal ring realizes the sealing of two positions：The end of sealing ring inwall and the first adhesive waterproof tape 22
Sealing is realized, prevents raw water from raw water side water inlet flow channel enters concentrated water survey water inlet flow channel from 22 ends；Exterior seal ring outer wall with
Putamina (shell of dress membrane component, putamina one end is provided with water inlet, and the other end is provided with concentrated water spout and pure water mouthful) sealing, it is ensured that raw water
It can only enter concentrated water side water inlet flow channel from raw water side water inlet flow channel after into putamina, prevent raw water from being flowed directly into separately along putamina inwall
The outlet of one end concentrated water), and then the water further obstructed in the water inlet flow channel of raw water side entered in the water inlet flow channel of concentrated water side.
The reverse-osmosis membrane element also includes the pure water flow-guiding screen 9 being arranged in production water flow passage and is separately positioned on raw water side
Water inlet flow-guiding screen 10 in water inlet flow channel and concentrated water side water inlet flow channel, the pure water flow-guiding screen 9 makes pure water towards the side of central tube 1
To flowing and being entered by inlet opening 6 in central tube 1, the water inlet flow-guiding screen 10 in the water inlet flow channel of the raw water side is entering water
Flowed in water flow passage towards the direction of central tube 1, the water inlet flow-guiding screen 10 in the water inlet flow channel of concentrated water side makes water in water inlet flow channel
Enter away from the direction flowing of central tube 1, the i.e. water inlet flow-guiding screen 10 in the water inlet flow channel of raw water side and positioned at concentrated water side
Water inlet flow-guiding screen 10 in water flow passage makes the in opposite direction of current.
In this embodiment, the plugging structure is included the relative positive two ends vertically of reverse osmosis membrane
The 3rd adhesive waterproof tape 21 and 23 mutually pasted, the 3rd adhesive waterproof tape 21 and 23 is limited respectively with the first adhesive waterproof tape 22
Concentrated water side water inlet flow channel and raw water side water inlet flow channel are determined.
The plugging structure also includes the second adhesive waterproof tape 11 for being bonded at hair infiltration diaphragm reverse side surrounding, second waterproof
