Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

With reference to Fig. 1, Fig. 3 and Fig. 5, solenoid valve of the present utility model comprises valve seat 109 and electromagnetic control assembly, has the water-inlet cavity 111 that communicates with water intake 115 in the valve seat 109, be arranged with flushing water cavity 112 in this water-inlet cavity 111, flushing water cavity 112 communicates with the flushing mouth of a river 110.Electromagnetic control assembly comprises the water shutoff assembly that is arranged on flushing water cavity 112 lower end mouth positions, and driving water shutoff assembly moves back and forth the execution member that flushing water cavity 112, water-inlet cavity 111 are changed under connection, blocking-up two states.Also be provided with concentrated water discharge mouth 101 in the fast valve seat 109 of institute, this concentrated water discharge mouth 101 communicates with water-inlet cavity 111.Because flushing water cavity 112, concentrated water discharge mouth 101 adopt design along separate routes, therefore the execution member by electromagnetic control assembly easily the switching controls domestic water purifying machine wash water route, concentrated water discharge water route, make wash water obtain cycling and reutilization, the conserve water resource, thus the user cost of domestic water purifying machine can be reduced.

Fig. 1 shows a kind of water shutoff assembly that can preferably adopt and carries out member.With reference to this figure, described water shutoff assembly comprises that its upper end can constitute the sealing gasket 2 of sealing to sparge water chamber 112 lower end mouth, and is fixed on the pressing plate 3 on sealing pad 2 lower end surfaces.The lower end mouth of described water-inlet cavity 111 is by 8 sealings of water shutoff sleeve.Described execution member comprises the coil block 7 that is arranged on outside the water shutoff sleeve 8.With reference to Fig. 1, the water shutoff assembly is normally closed, is in the state that communicates all the time between concentrated water discharge mouth 101 and the water-inlet cavity 111, and the dense water of discharging is normally carried out.When reverse osmosis membrane is washed, send instruction by the control circuit of water purification machine, coil block 7 energisings, the water shutoff assembly is descending under the effect of electromagnetic force, and flushing water cavity 112, water-inlet cavity 111 are communicated with, flushing water route conducting.

Be the hydraulic pressure in the quick removal flushing water cavity 112 when coil block 7 cuts off the power supply, the water shutoff assembly is resetted be sealed into the lower end mouth of water cavity 111, with reference to Fig. 1, described sealing gasket 2 and pressing plate 3 with flushing water cavity 112 lower end mouth, the corresponding position of water-inlet cavity 111 ports on offer leading discharge orifice 1, secondary pod apertures 9 respectively.Be provided with the biography magnetic bar 5 that is driven by coil block 7 in the described water shutoff sleeve 8, it is coaxial with leading discharge orifice 1 that this passes magnetic bar 5, and its upper end portion is provided for sealing the sealing head 4 of dominating discharge orifice 1 lower end mouth, and is provided with spring 6 between its lower end and water shutoff sleeve 8 diapires.

For the hydraulic pressure in the reverse osmosis membrane filtration unit influent side cavity being controlled at the scope of setting, be provided with choked flow pressure release assembly in the described concentrated water discharge mouth 101.With reference to Fig. 2 and Fig. 3, Fig. 4 and Fig. 5, described choked flow pressure release assembly comprises the interior cover 106 of choked flow overcoat 105, choked flow of suit, extend in the choked flow within the cover 106 in the hole passage that cover 106 and gap formation between the choked flow overcoat 105 supply dense water to pass through in cover 106, the choked flow in choked flow bar 107 and the choked flow with the choked flow bar 107 of choked flow overcoat 105 one.The spring fastener 102 that also has been threaded in the described concentrated water discharge mouth 101 is provided with spring 104 between this spring fastener 102 and the choked flow overcoat 105.The dense water that is discharged by overlap 106 in choked flow overcoat 105, the choked flow, clearance channel between the choked flow bar 107 passes through, when hydraulic pressure surpasses setting value in filtering the unit, choked flow overcoat 105 is at dense water effect lower compression spring 104, make the shorten length of the clearance channel between the cover 106 in choked flow overcoat 105, the choked flow, concentrated water discharge speeds up, and reaches the purpose of pressure release.When hydraulic pressure was lower than setting value in filtering the unit, choked flow overcoat 105 held the length that makes the clearance channel between the cover 106 in choked flow overcoat 105, the choked flow under the effect at pressure spring 104 and increases, and concentrated water discharge speed slows down, and reaches the purpose of keeping hydraulic pressure.

Showing two specific embodiments respectively by Fig. 2 and Fig. 3, Fig. 4 and Fig. 5 in this specification, is not to be that the utility model is limited on the concrete structure shown in it.On this basis every, any remodeling and be equal to replacement all belongs to protection domain of the present utility model.
