Abstract
The utility model discloses an electromagnetic valve which is used for a reverse osmosis filtering system for a water-purifying machine and can automatically wash; the circuit is provided with a delay circuit which is connected in parallel with the pressure pump circuit for the water-purifying machine; a current-limit pin hole is communicated between the front and the back hole passages of the electromagnetic valve and is provided with a filtering net. When water is made, the delay circuit makes the electromagnetic valve open the valve automatically for certain time before closed; when the valve is opened, high pressure water, which comes from the pressure pump at the front of a RO membrane tube for the reverse osmosis filtering system for a water-purifying machine, drains the impurities through a normal passage of the electromagnetic valve, meeting the result of reverse washing the RO membrane tube; the electromagnetic valve automatically closes and restores to the status of not communicating, water passes through the filtering net before enters the hole passage and forms supercharging and normal water making; the current-limit pinhole is communicated and can avoid the blocking the RO membrane tube and increase the system function. The electromagnetic valve makes the reverse osmosis filtering system for the water-purifying machine save the cost for a waste water ratio, a manual ball valve, a four-surface valve and a connector and promotes the automation function of the system.
Description
Affiliated technical field
The utility model relates to a kind of solenoid valve, especially relates to a kind of solenoid valve that is used for the water purifier reverse osmosis filtration system, can washes automatically.
Background technique
The existing reverse osmosis filtration system that is used for water purifier, its principle is to utilize high pressure to force water molecule to penetrate to have the RO film pipe that is commonly called as of superfine little micropore to come impurity screening, it requires tap water or water source through one to three-stage filtration, through reach before arriving RO film pipe behind the pressure pump greater than 60 and less than 125 pounds/could produce purified water per square inch.The reverse osmosis filtering process of water purifier purified water generally be tap water after filtration, lower pressure switch, entering water electromagnetic valve, high-pressure water pump, RO reverse osmosis membrane pipe, one-way valve, four-sided valve or waste water ratio add manual ball valve, high-voltage switch gear, pressure water storage barrel, depotition cock; The design of lower pressure switch and entering water electromagnetic valve is for the protection high-pressure water pump be the usefulness of idle running, when source pressure be lower than 5 pounds/power supply of lower pressure switch disconnection, entering water electromagnetic valve can be closed per square inch the time, avoid high-pressure water pump to dally and burn out its motor; When source pressure greater than 5 pounds/per square inch the time, solenoid valve and lower pressure switch are opened the connected system water route, water is made in the supercharging of beginning water pump, the effect of proportional throttle valve is the pressure difference that causes for after the supercharging of RO film pipe behind the RO film pipe, when making it inflow greater than water-outlet quantity, produce the RO mould and strengthen, fine hair designs throttle valve with regard to forming permeable penetration theory on the diaphragm, make its feedback back pressure, it is permeable that the RO film is produced; Proportional throttle valve is exactly a pin hole valve in fact, and the water of pin hole is seldom or cutout because the throttling action of pin hole is flowed through when the pressure before the valve is little; The water that flows through pin hole when the pressure before the valve is too big is just many more, reduces the preceding pressure of valve; Since impurity can not penetrate have a superfine little micropore be commonly called as RO film pipe (this is the purpose of water purifier just), so at RO film Guan Qianhui savings impurity is arranged in the course of time, need the water recoil to clean, so become two branches after the waterexit end of general RO reverse osmosis membrane pipe, the one, drain opening, another is the pure mouth of a river, Proportional valve is in parallel with a solenoid valve or manual ball valve in the drain opening branch, when needs wash, the push button startup solenoid valve or the personnel selection of manually pressing on the water purifier are turned on ball valve by the water pressure release, and the high pressure water before the RO film pipe is gone out drain opening with the foreign material mud of RO film pipe.But this just makes troubles to the user, if forget this thing, uses rear impurity the pipe choking of RO film can be brought a series of consequences for a long time.
The model utility content
The purpose of this utility model, just be to provide a kind of and can save traditional proportional throttle valve, improve intelligent, waste water resource no longer after the full water level, reduce cost, can play backwash RO film pipe function again simultaneously in the same old way, prevent that manual ball valve not being opened contrary flushing RO film pipe because of human negligence piles up on the diaphragm mud impurity, causes the diaphragm occlusive effects to make the solenoid valve that the water purifier reverse osmosis filtration system can be washed automatically that is used for of water quality.
For achieving the above object: the solenoid valve that is used for the water purifier reverse osmosis filtration system of the present utility model, comprise valve seat, valve body, spool, coil, the valve seat two ends respectively have blind hole, and bypass is respectively arranged at the bottom of two blind holes, and both sides route axis disconnects with the spool end of valve seat axis normal or is communicated with; Valve core housing is in valve body, and coil and coil cap are enclosed within outside the valve body, and the spool hypomere is set with the spool return spring outward, is stuck in valve body lower end flange and valve base chamber, valve body overcoat coil; It is characterized in that: the compression pump circuit of delay circuit, itself and water purifier reverse osmosis filtration system is housed on the described electromagnetic valve circuit and connects; There is the current limliting pin hole to communicate between the blind hole of described valve seat two ends.
On the described current limliting pin hole filter screen is arranged.
The beneficial effects of the utility model are: owing on the electromagnetic valve circuit delay circuit is housed and with water purifier compression pump circuit and connect, both link to each other and be moving, and have the current limliting pin hole to communicate between the blind hole of valve seat two ends; When water was made in start, delay circuit cut out after can making described solenoid valve automatic valve opening certain hour automatically; The high pressure water that is come by compression pump before the RO film pipe during automatic valve opening is discharged impurity by electromagnetic valve drain opening path, promptly reach the effect of backwash RO film pipe; Solenoid valve cuts out the drain opening path automatically and recovers the obstructed state of blind hole afterwards, and water is gone into blind hole and formed supercharging and normally make water through filter screen is laggard; So can avoid the RO diaphragm to stop up and increase systemic-function, make the water purifier reverse osmosis filtration system save the cost of a waste water than, manual ball valve and four-sided valve and connecting head, and the automation function of elevator system.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic representation of water purifier reverse osmosis filtration system.
Fig. 2 is in the sectional drawing of off state for the utility model solenoid valve.
