When entering water electromagnetic valve is installed, iron core is loaded in mounting, then return spring seat is loaded, again return spring is loaded in spring base, then by fixed cover pressure assigned address, finally relief hole sealing gasket is loaded the assigned address of spring base, this constitutes mounting assembly.Be inserted in by joint in hold-down nut, the screw thread place on hold-down nut adds anaerobic adhesive, and then screwed in valve body by joint, then filter screen is loaded the assigned address of valve body, this forms valve component.Diaphragm is loaded the assigned address of disk, component film chip module.Diaphragm unit is loaded the relevant position of valve component.Then back taper spring is being loaded onto.In the by-pass prot of the wherein long-armed insertion diaphragm unit of back taper spring, then respectively mounting assembly, coil are loaded, finally stamp four screws, during use, magnetic valve is in normally open, control sealing gasket by electric control gear close and open the relief hole on disk thus realize closing and opening valve, structure is simple, good seal performance, assembling is simple, achieve automatic control, be active in one's movements, improve production efficiency, thus improve the reliability of product, sealed valve body and electric control gear is come by diaphragm, such sealing property is better, the requirement of Water intaking valve of water heater can be reached, by the acting in conjunction of long-armed bar and by-pass prot and through hole, filter the incrustation scale entered in by-pass prot, prevent incrustation scale from entering in valve pocket, realize excellent sealing when magnetic valve closes, moving up and down of control block frame component is carried out by the energising of coil and power-off, the iron core band flexible spring seat of mounting assembly moves up and down, thus drive sealing gasket to move up and down, return spring is used for spring base and gets back to original position, fixed cover plays fixing and sealing function, impurity in strainer filtering water inlet pipe, prevent impurity from entering into magnetic valve inside, joint is convenient to be connected with outlet pipe, the convenient fixing outlet pipe of hold-down nut.
When water-drainage solenoid valve uses, control device realizes the switch of magnetic valve by control sealing block and sealing ring, when water feeding of heater or blowdown, water-drainage solenoid valve is opened, and now outside air is communicated with water heater liner by the exhaust outlet of water heater, when water-drainage solenoid valve is energized, magnetic core moves upward, and achieves water heater liner and is communicated with extraneous, when electric heater cleaning blowdown, water yield can be prevented more and more less, thus improve contaminant removal effectiveness; After blowdown completes, to water feeding of heater, along with the rising of inner bag water level, air pressure in inner bag slowly raises, air pressure in inner bag is greater than ambient pressure, inner bag water inlet efficiency is caused to reduce, and make in inner container of electric water heater, to be mixed into air, after heating, the expansion ratio water of air is large, be in communication with the outside so will produce very high pressure, ensure that the safety of water heater, reliability service and improve into water efficiency, sealing ring plays sealing function, prevent from leaking between control device and outbreak, water-drainage solenoid valve is normally closed solenoid valve.
The present invention adopts automatic blowdown system, controls with remote controller.During blowdown, blowoff electromagnetic valve is opened, and entering water electromagnetic valve is closed, because the water level in inner bag slowly reduces, inner bag internal gas pressure reduces, and causes inside and outside inner bag and has draught head, and when causing blowdown, water yield reduces, contaminant removal effectiveness reduces, and in order to eliminate this phenomenon, is provided with pressure compensation opening at water-drainage solenoid valve.Air by pipeline to air inlet in inner bag.Now water-drainage solenoid valve is opened, and in order to realize this function, blowoff electromagnetic valve adopts electrical ball valve, and entering water electromagnetic valve and water-drainage solenoid valve adopt magnetic valve, and the wire of these three valves is connected with control panel, as long as user can realize blowdown operation with remote controller operation; During blowdown, these three valves are all in "on" position.After blowdown completes, blowoff electromagnetic valve is closed, water feeding of heater, entering water electromagnetic valve is opened (this is normally open valve), now entering water electromagnetic valve coil blackout state, inner bag water level slowly raises, air pressure now in inner bag is greater than the air pressure outside inner bag, causes into water difficulty, in order to eliminate this phenomenon, water-drainage solenoid valve is opened (this is normally close valve), now water-drainage solenoid valve coil electricity, the gas in inner bag is discharged by the pressure compensation opening of water-drainage solenoid valve, realize in but inside and outside air pressure balance, when water is full of pipeline, water-drainage solenoid valve is closed automatically.When water heater do not intake or not blowdown time, entering water electromagnetic valve, water-drainage solenoid valve, blowoff electromagnetic valve are all in off-position; Constitute water-heater system like this.
Above-mentioned detailed description of the invention is used for explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
