Description
Technical field
The utility model relates to water purification system technical field, is specifically related to a kind of pressure-bearing type RO membrane filtration bottle.
Background technology
Along with improving constantly of people's living standard, the quality of people to tap water is also more and more paid attention to, water-purifying machine becomes the selection of most of human consumer, current traditional RO membrane filtration bottle is in water purification operation process, the pure water inlet of RO membrane filtration bottle is directly connected by PE flexible pipe with pressure-pot usually, pressure-pot mainly stores the effect of water, because reverse osmosis water outlet is very slow, very fast with water outlet during pressure-pot water storage water, due to pressure-pot directly with RO membrane filtration bottle directly to being communicated with, when not water outlet, RO membrane cartridge is in the pressure effect of pressure-pot always, the refluence of water purification is also there will be when not water outlet, RO membrane cartridge is under long-term pressure effect, not only can affect its purifying water effect, but also the work-ing life of RO film can be affected.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of pressure-bearing type RO membrane filtration bottle, the utility model efficiently solves traditional RO membrane filtration bottle in stopping Water treatment, because filter flask is directly communicated with pressure-pot, under causing RO filter core to be in pressure effect for a long time, not only can cause the water purification reflux problem in pressure-pot, and can affect RO membrane cartridge purifying water effect and work-ing life problem.
The utility model is achieved through the following technical solutions:
A kind of pressure-bearing type RO membrane filtration bottle, comprise RO membrane filtration bottle (1), RO membrane filtration bottle (1) is provided with water entry (2), water purification passage (3), RO membrane cartridge (4) is provided with in RO membrane filtration bottle (1), described RO membrane filtration bottle (1) comprises filter flask lid (5), bottle (6), described water entry (2) is arranged at filter flask lid (5) middle position, water purification passage (3) is arranged at bottle (6) bottom, it is characterized in that: be provided with one-way check valvegear (8) in the water purification passage (3) of described bottle (6) bottom.
The further Technological improvement plan of the utility model is:
Described one-way check valvegear (8) comprises L-type housing (81), L-type housing (81) one end is water purification import (82), it is pure water inlet (83) to opposite end, water purification import (82), pure water inlet (83) is provided with Sealed casing pipe (84), the Sealed casing pipe (84) that one-way check valvegear (8) is held by water purification import (82) is tightly connected with water purification passage (3), L-type housing (81) inside is provided with check ball (85), nearly pure water inlet (83) end of check ball (85) is connected with L-type housing (81) inwall elasticity by spring (86), nearly water purification import (82) end of check ball (85) is provided with hollow snap ring (87).
The further Technological improvement plan of the utility model is:
Described one-way check valvegear (8) water purification import (82) end is fixedly connected with water purification passage (3), and pure water inlet (83) end is connected with pressure-pot by PE flexible pipe.
The further Technological improvement plan of the utility model is:
Described water purification passage (3) side is also provided with waste water tunnel (7), waste water tunnel (7) is provided with capillary waste water plug (9).
The utility model compared with prior art, has following obvious advantage:
One, the utility model arranges one-way check valvegear on the water purification passage of traditional RO membrane filtration bottle, the pressure of pressure-pot when not carrying out water purification operation is made to be enclosed in pressure-pot side by check ball, not only water purification can not be back in filter core, it also avoid filter core and bear pressure-pot pressure for a long time, thus raising purifying water effect, also extend the work-ing life of RO film simultaneously.
Two, the waste water tunnel of the utility model bottom traditional RO membrane filtration bottle arranges capillary waste water plug, it is outside that the kapillary of waste water in discharge process under the internal pressure of RO filter flask in capillary waste water plug discharges bottle, because capillary diameter is very thin, in RO filter flask water purification discharge process, affect the aquifer yield of water purification passage hardly, thus improve the cleaning water of traditional RO membrane filtration bottle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model one-way check valve structure schematic diagram.
Embodiment
As shown in Figure 1, 2, the utility model comprises RO membrane filtration bottle 1, RO membrane filtration bottle 1 is provided with water entry 2, water purification passage 3, RO membrane cartridge 4 is provided with in RO membrane filtration bottle 1, described RO membrane filtration bottle 1 comprises filter flask lid 5, bottle 6, described water entry 2 is arranged at filter flask lid 5 middle position, and water purification passage 3 is arranged at bottom bottle 6, is provided with one-way check valvegear 8 in the water purification passage 3 bottom described bottle 6; One-way check valvegear 8 comprises L-type housing 81, L-type housing 81 one end is water purification import 82, it is pure water inlet 83 to opposite end, water purification import 82, pure water inlet 83 are provided with Sealed casing pipe 84, one-way check valvegear 8 is tightly connected with water purification passage 3 by the Sealed casing pipe 84 of water purification import 82 end, L-type housing 81 inside is provided with check ball 85, nearly pure water inlet 83 end of check ball 85 is connected with L-type housing 81 inwall elasticity by spring 86, and nearly water purification import 82 end of check ball 85 is provided with hollow snap ring 87; Described one-way check valvegear 8 water purification import 82 end is fixedly connected with water purification passage 3, and pure water inlet 83 end is connected with pressure-pot by PE flexible pipe, and described water purification passage 3 side is also provided with waste water tunnel 7, waste water tunnel 7 is provided with capillary waste water plug 9.
Composition graphs 1,2 sketches the backwash process of filter flask of the present utility model:
In filter flask device normal operation process, former water enters RO membrane filtration bottle 1 from the water entry 2 of filter flask lid 5, and purify through RO membrane cartridge 4, the water purification passage 3 of former water bottom bottle 6 through purifying enters the water purification import 82 of one-way check valvegear 8, water through purification is also pushed open check ball 85 by hollow snap ring 87 under the effect of the pressure and enters PE flexible pipe by pure water inlet 83, thus enter pressure-pot connection, the waste water simultaneously produced in the former water process of purification, the kapillary 82 of the capillary waste water plug 9 of clamping in waste water tunnel 7 discharges RO membrane filtration bottle 1 outside,
When filter flask device does not carry out water purification operation, the pressure of pressure-pot inside promotes check ball 85, and check ball 85 withstands hollow snap ring 87, thus the water purification in pressure-pot cannot be back in filter flask, and inner pressure also can not act on RO membrane cartridge always.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
