Abstract

The invention discloses an electricity-free low-pressure discontinuous water supply water purification machine. According to the electricity-free low-pressure discontinuous water supply water purification machine, a water inlet pipe and a waste water pipe in front of a flow restrictor are connected via a connection pipe, so that when a pressure water storage barrel is filled with water, or the pressure of a purified water pipe is increased, a water inlet is closed by a four-way valve; when other water faucets sharing a same water pipe with the electricity-free low-pressure discontinuous water supply water purification machine are used, water pressure in the water pipe is reduced, water flows from the waste water pipe into the water inlet pipe via the connection pipe because of the high pressure in a RO membrane shell assembly, and RO membrane is washed; a spring arranged on a starting membrane sheet of the four-way valve is capable of ensuring that the pressure of a long passage pressure supply end of the four-way valve is always larger than that of a water inlet-outlet open-close end, so that it is beneficial for rapid close of the four-way valve, and waste of waste water is reduced.

The present invention has the following advantages without can the cut off the water supply structure tool of water purification machine of electric low pressure: the waste water water pipe before water inlet water pipe and waste water ratio is communicated with by connecting leg, when in the time that pressure pot water is full or DI pressure raises, four-sided valve is closed water-in like this, the resistance of RO putamina group internal cause waste water ratio can cause and close resistance, cause to close and delay, and the effect of connecting leg can be derived pressure in water inlet water pipe, is beneficial to and close water-in; In the time of the first-class water of other fire hoses of the same water pipe of water purification machine, can cause the hydraulic pressure in water pipe to reduce, at this moment the elevated pressures in RO putamina group flows into from waste water water pipe water the effect of intaking in water pipe, playing flushing RO film by connecting leg, be more conducive to the quick closedown of four-sided valve, the lower effect of former water hydraulic pressure pressure is better simultaneously; The effect of connecting leg check valve is that the water that ensures water inlet water pipe does not directly enter waste pipe.In four-sided valve, start the spring above diaphragm, can make the length of four-sided valve lead to be a bit larger tham all the time Inlet and outlet water to the pressure of pressure side to open and close end, be conducive to the quick closedown of four-sided valve, and start in four-sided valve, pressure that the spring above diaphragm sets is less not to be affected water inlet and passes through in four-sided valve.

Brief description of the drawings

Fig. 1 is the present invention without the electric low pressure water purification machine structure iron of can cutting off the water supply.

Embodiment

Further illustrate the present invention without can the cut off the water supply embodiment of water purification machine of electric low pressure below in conjunction with accompanying drawing: the present invention shown in Fig. 1 is without the electric low pressure water purification machine of can cutting off the water supply, by water inlet pipe 9, RO putamina group 20, four-sided valve 1, pressure water storage barrel 8, pure water check valve 18, DI 19, waste pipe 17, waste water ratio composition 10, the exit end mouth of pipe 21 that the Inlet and outlet water of four-sided valve 1 opens and closes end connects RO putamina group 20, the length of four-sided valve 1 lead to pressure side left port 7 and long lead to connect respectively pure water check valve 18 to pressure side right output port 8 after and before pressure water storage barrel 5 between DI 19 on, on waste pipe 17, there is waste water ratio 10, the feed-water end mouth of pipe 22 that the Inlet and outlet water of four-sided valve 1 opens and closes end taps into water Three-way joint for water pipe 10, before the waste water ratio 10 of waste pipe 17, there is waste water Three-way joint for water pipe 12, water inlet Three-way joint for water pipe 10 and waste water Three-way joint for water pipe 12 are communicated with by connecting leg 11, on connecting leg 11, there is connecting leg check valve 13.In four-sided valve 1, have upper startup diaphragm 3, lower startup diaphragm 2, between upper startup diaphragm 3 and lower startup diaphragm 2, have jacking block 6, lower startup diaphragm 2 has water-in 14 and water outlet 15 below, on start diaphragm 3 and between the shell of four-sided valve 1, has spring 4.
