Description
Technical field
This utility model is related to water purifier technical field, more particularly to a kind of water purification with normally opened waste water electromagnetic valve
Machine.
Background technology
With social development, the improvement of people's living standards, health is increasingly paid attention to, the requirement to drinking water is also more next
Higher, household water filter has begun to popularization；
In order to reduce the discharge of water purifier waste water, waste water ratio is done into little typically all, but while waste water is reduced, band
It is exactly effectively can not to close after entering water electromagnetic valve power-off to carry out a problem, and reason is affected by hydraulic pressure, cost, water purifier water inlet
Electromagnetic valve is guide electromagnetic valve, needs intake-outlet pressure differential more than 0.02MPa, effectively could close, if waste water ratio sets
When counting below 200mL, after entering water electromagnetic valve with Pump Failure, the pressure differential of entering water electromagnetic valve rear and front end is zero, it is impossible to
Effectively close, wastewater flow is constantly in zero less than the leakage flow of entering water electromagnetic valve before and after causing water intaking valve, waste water is always
Stream.
Accordingly, it is desirable to provide a kind of water purifier with normally opened waste water electromagnetic valve is solving above-mentioned technical problem.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of water purifier with normally opened waste water electromagnetic valve, waste water
Valve is arranged to open in usual, when water purifier quits work, vent flow of the entering water electromagnetic valve vent flow less than wastewater valve so that water inlet
The pressure differential of electromagnetic valve rear and front end is more than zero, entering water electromagnetic valve quick closedown, and then reach the mesh of effective restraint waste water earial drainage
, so as to effectively reduce the leakage of waste water.
The technical scheme that this utility model is provided is to provide a kind of water purifier with normally opened waste water electromagnetic valve, including first
Level filter element 1, second level filter element 2, third level RO membrane cartridges 3, fourth stage filter element 4, normally closed entering water electromagnetic valve 5, water pump 6, pressure pot
7th, faucet 8, the connection water inlet of first order filter element 1, its outlet connect normally closed 5 one end of entering water electromagnetic valve, normally closed water inlet electromagnetism
5 other end of valve connects 2 water inlet of second level filter element, and 2 outlet of second level filter element connection 6 water inlet of water pump, 6 outlet of water pump connect
Third level RO membrane cartridges 3 are connect, the pure water inlet point two-way of third level RO membrane cartridges 3 connects 7 water inlet of pressure pot all the way, another
Road connects 4 water inlet of fourth stage filter element, and 4 water purification mouth of fourth stage filter element connection faucet 8, the sewage of third level RO membrane cartridges 3 go out
Mouth one normally opened waste water electromagnetic valve 9 of connection, during controlling the water circulation, normally opened Wastewater by Electric magnet valve 9 is powered, and built-in waste water ratio comes into force, and stops controlling the water circulation
When, normally opened 9 power-off of waste water electromagnetic valve is shown in a fully open operation, built-in waste water ratio failure.
Water purifier with normally opened waste water electromagnetic valve of the present utility model, wastewater valve are arranged to open in usual, stop in water purifier
When only working, vent flow of the entering water electromagnetic valve vent flow less than wastewater valve so that the pressure differential of entering water electromagnetic valve rear and front end is big
In zero, entering water electromagnetic valve quick closedown, and then the purpose of effective restraint waste water earial drainage is reached, so as to effectively reduce letting out for waste water
Leakage.
Description of the drawings
Fig. 1 is two visual angles of the first preferred embodiment of the water purifier with normally opened waste water electromagnetic valve of the present utility model
External structure schematic diagram.
Specific embodiment
The technical solution of the utility model is described in detail with reference to diagram.
Refer to Fig. 1, the water purifier with normally opened waste water electromagnetic valve of first preferred embodiment of the present utility model, including
First order filter element 1, second level filter element 2, third level RO membrane cartridges 3, fourth stage filter element 4, normally closed entering water electromagnetic valve 5, water pump 6, pressure
Power bucket 7, faucet 8, the connection water inlet of first order filter element 1, its outlet connect normally closed 5 one end of entering water electromagnetic valve, normally closed water inlet
5 other end of electromagnetic valve connects 2 water inlet of second level filter element, 2 outlet of second level filter element connection 6 water inlet of water pump, 6 water outlet of water pump
Mouth connection third level RO membrane cartridges 3, the pure water inlet point two-way of third level RO membrane cartridges 3, connect 7 water inlet of pressure pot all the way,
Another 4 water inlet of road connection fourth stage filter element, 4 water purification mouth of fourth stage filter element connection faucet 8, the dirt of third level RO membrane cartridges 3
Water out connects a normally opened waste water electromagnetic valve 9.
The operation principle of the present embodiment is as follows：
During system controlling the water circulation, water pump 6, normally closed entering water electromagnetic valve 5, normally opened waste water electromagnetic valve 9 are powered, normally opened waste water electromagnetic valve
9 built-in waste water ratios come into force, normal controlling the water circulation；When quitting work, water pump 6,5 power-off of normally closed entering water electromagnetic valve, normally opened waste water electromagnetic valve 9
In normally open, built-in waste water ratio failure, quick pressure releasing, 5 leakage flow of normally closed entering water electromagnetic valve are less than normally opened waste water electromagnetism
9 drawoff discharge of valve, 5 pressure at two ends of normally closed entering water electromagnetic valve difference are more than 0.02MPa, reach the quick purpose for effectively closing water, so as to
So that waste water will not earial drainage always.
Water purifier with normally opened waste water electromagnetic valve of the present utility model, wastewater valve are arranged to open in usual, stop in water purifier
When only working, vent flow of the entering water electromagnetic valve vent flow less than wastewater valve so that the pressure differential of entering water electromagnetic valve rear and front end is big
In zero, entering water electromagnetic valve quick closedown, and then the purpose of effective restraint waste water earial drainage is reached, so as to effectively reduce letting out for waste water
Leakage.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure made using this utility model description and accompanying drawing content, or directly or indirectly it is used in other related technologies
