Embodiment: describe the embodiment of the present invention 1 below in conjunction with accompanying drawing and a preferred embodiment:
Fig. 1 is that a kind of two-pass reverse osmosis film or the water-purifying machine of nanofiltration membrane or ultra-filtration membrane or the structure of water purifying plant analyse and observe diagram:
(1), strainer virgin state: all terminal valves are all in closure state.
(2), two water route water converges the process manufacturing water purification:
Water enters into connecting passage 1A (1A) from water-in (1), 0 grade or 1 grade or be greater than 1 grade of preposition filter core (2), connecting passage 2A1 (2A1), 0 or 1 or be greater than 1 pump (1B) dynamic action under, water from threeway 2B (2B) through connecting passage 2A2 (2A2), enter into 0 grade or 1 grade or be greater than 1 grade of mid-filter core one (31) and carry out filtering or processing, again through connecting passage 3A1 (3A1), the water purification entering into a RO film or nanofiltration membrane or ultrafiltration membrane filter element (41) brings out mouth, enter into connecting passage 4A (4A), threeway 4B1 (4B1), connecting passage 4A3 (4A3), threeway 4B4 (4B4), connecting passage 4A5 (4A5), machinery or electron pressure switch 61 (61), water purification or pure water flow out from the first water purification interface or valve (81), the process of the Article 1 path filtering of two water routes of Here it is water purification or pure water.
Meanwhile, water from threeway 2B (2B) through connecting passage 2A3 (2A3), threeway 4B3 (4B3), connecting passage 2A4 (2A4), enter into 0 grade or 1 grade or be greater than 1 grade of mid-filter core two (32) and filter or process, water is again through connecting passage 3A2 (3A2), enter into the 2nd RO film or nanofiltration membrane or ultrafiltration membrane filter element (42) to filter or process, water purification or pure water are through connecting passage 4A2 (4A2) and threeway 4B2 (4B2), through connecting passage 4A3 (4A3), threeway 4B4 (4B4), machinery or electron pressure switch 61 (61), flow out from the first water purification interface or valve (81), the process of two water route Article 2 path filtering of Here it is water purification or pure water.
First and second water purification of paths filtration of two water route or converging of pure water, constitute the filtration of two film such as two reverse osmosis membrane filter element, thus, realize comparatively big yield, when the water yield is enough large, the pressure water storage barrel occupying volume larger space of conventional reverse osmosis film machine can be omitted.
(3), secondary membrane such as reverse osmosis membrane filtration manufactures the process of water purification or pure water:
(1), according to actual needs, magnetic valve 91 (91) preferably adopts normally closed valve, when adopting normally closed valve, when power is off, magnetic valve 91 (91) is in normally off, be in normally open during energising, when pressure that is mechanical or electron pressure switch 61 (61) reaches set(ting)value, magnetic valve 91 (91) cuts out automatically; Magnetic valve 92 (92) preferably adopts normally open valve.
(2), when closedown first water purification interface or valve (81), because hydraulic pressure continues to increase, machinery or electron pressure switch 61 (61) Self-shut electromagnetic valve 91 (91) when pressure reaches set(ting)value, now, magnetic valve 92 (92) can automatically be opened.
(3) when opening the first water purification interface or valve (81), can simultaneously Self-shut electromagnetic valve 92 (92) when magnetic valve 91 (91) is opened, thus ensure that the filtration pure water that such as reverse osmosis membrane filter element filters of the first step cannot enter into 0 or 1 or be greater than among 1 internal airbag or pressure water storage chamber or rearmounted filter core (7).
(4), water from threeway 2B (2B) through connecting passage 2A2 (2A2), enter into 0 grade or 1 grade or be greater than 1 grade of mid-filter core one (31) and carry out filtering or processing, again through connecting passage 3A1 (3A1), the water purification entering into a RO film or nanofiltration membrane or ultrafiltration membrane filter element (41) brings out mouth, enter into connecting passage 4A (4A), threeway 4B1 (4B1), then enter into connecting passage 4A1 (4A1), water is again through threeway 4B3 (4B3), connecting passage 2A4 (2A4), enter into 0 grade or 1 grade or be greater than 1 grade of mid-filter core two (32) and filter or process, water is again through connecting passage 3A2 (3A2), enter into filtration or process that the 2nd RO film or nanofiltration membrane or ultrafiltration membrane filter element (42) carry out secondary, now, the water quality of water purification or pure water is better, finally, water purification or pure water are through connecting passage 4A2 (4A2) and threeway 4B2 (4B2) and connecting passage 4A4 (4A4), water continues through magnetic valve 92 (92) and enters into 0 or 1 or be greater than in 1 internal airbag or pressure water storage chamber or rearmounted filter core (7) and store, due to shut electromagnetic valve 91 (91) time can link or automatically open magnetic valve 92 (92), magnetic valve 91 (91) can link when being opened or Self-shut electromagnetic valve 92 (92), this guarantees the water that the water entering 0 or 1 or be greater than 1 internal airbag or pressure water storage chamber or rearmounted filter core (7) is through cascade filtration or process, finally, water flows out from the second water purification interface or valve (82), the complete procedure of Here it is cascade filtration or process.
(4), 0, auto-switch or 1 or be greater than the process of 1 pump (1B):
Due to 0 or 1 or be greater than 1 pump (1B) and be connected with machinery or electron pressure switch 61 (61) and mechanical or electron pressure switch 62 (62) respectively, when hydraulic pressure reaches the force value of setting, machinery or electron pressure switch 61 (61) and machinery or electron pressure switch 62 (62) control 0 or 1 or be greater than the switch of 1 pump, after water system is full, no matter be open the first water purification interface or valve (81), still the second water purification interface or valve (82) is opened, 0 or 1 or be greater than 1 pump (1B) and all can automatically start water processed, after the first water purification interface or valve (81) and the second water purification interface or valve (82) are closed simultaneously, when hydraulic pressure is elevated to machinery or the electron pressure switch value of setting, 0 or 1 or be greater than 1 pump (1B) and will automatically close.
