In above-mentioned invention, the built-in valve of tandem is the core component of fluid level control valve, be arranged in fluid level control valve and use, during concrete enforcement, the diameter design of main valve plate (108) is 15-35mm, the diameter design of pressure releasing valve core (111) is 3-5mm, main valve plate (108) and pressure releasing valve core (111) are controlled by the lifting of float (3) to close or open, when hydroecium (IV) middle water level in fluid level control valve rises, float (3) drives pressure releasing valve core (111) and main valve plate (108) to rise by connecting rod (103) and runs to closing direction, pressure releasing valve core (111) is identical with the direction of current with the closing direction of main valve plate (108), valve is easily closed, after fluid level control valve is closed, valve pocket (I) bears the pressure of tap water, the closing direction of main valve plate (108) and pressure releasing valve core (111) and the direction of valve pocket (I) interior tap water pressure and identical, utilize the pressure of tap water that fluid level control valve is closed tight, when hydroecium (IV) middle water level in fluid level control valve declines, float (3) is along with decline, pressure releasing valve core (111) is driven to decline by connecting rod (103), because the cross section of pressure releasing valve core (111) is very little, therefore, the resistance that pressure releasing valve core (111) declines is very little, the gravity of float (3) is easy to drive pressure releasing valve core (111) to decline, open pressure release passage (104), make the earth pressure release in valve pocket (I), thus main valve plate (108) is fallen, circulation road of fetching boiling water (II) makes fluid level control valve open.Moving element of the present invention only has float (3), main valve plate (108) and pressure releasing valve core (111), and only moves up and down vertically, and has that structure is simple, a feature of reliable operation, the tight water-tight and long service life of closedown, and easy to install.In the present invention, pressure releasing valve core (111) is designed to cylindrical body or the conical structure of small bore, pressure releasing valve core (111) opens element as main valve plate (108) is auxiliary, the cross section of pressure releasing valve core (111) is far smaller than the cross section of main valve plate (108), when built-in valve cuts out, tap water pressure in valve pocket (I) is mainly applied on main valve plate (108), and main valve plate (108) is upwards compressed, and makes closedown tighter, when the diameter design of pressure releasing valve core (111) is 3mm, when tap water pressure in valve pocket (I) is 0.2MPa, the pressure that pressure releasing valve core (111) bears is below 0.015MPa, only need the gravity of 0.15kg that pressure releasing valve core (111) just can be made to open, when hydroecium (IV) middle water level in fluid level control valve declines, when the float (3) of more than 0.15kg weight is along with decline, be easy to drive pressure releasing valve core (111) to decline, open pressure release passage (104), make the earth pressure release in valve pocket (I), after earth pressure release in valve pocket (I), main valve plate (108) makes fluid level control valve open with regard to smooth opening, because connecting rod (103) is in pressure release passage (104), connecting rod (103) is movable along with the lifting of float (3), makes pressure release passage (104) plugging fault can not occur.The object that the present invention arranges dividing plate (6) and damping plate (5) in valve pocket (I) is in order to when pressure releasing valve core (111) is opened, the top energy pressure release smoothly of valve pocket (I), thus guarantees main valve plate (108) energy smooth opening, damping plate (5) selects the material of proportion slightly larger than water, when pressure releasing valve core (111) is opened, main valve plate (108) is not yet opened, current are little, damping plate (5) can not by top from dividing plate (6), damping plate (5) has isolated the water of valve pocket (I) bottom, the pressure on valve pocket (I) top is discharged, after main valve plate (108) is opened, water flow increases, damping plate (5) is pushed up from dividing plate (6), the water of valve pocket (I) bottom enters into the top of valve pocket (I) by water passage hole (602), then through flow channel (II), current via hole (114), water outlet (III) enters into hydroecium (IV).
The automatic water level that the using scope of foregoing invention comprises solar water heater, the water tank of central heating system, the water tower of industrial and mining enterprise, fire-water pond and boiler replenishing water case controls.When the present invention applies on solar water heater, useful improvement can be carried out to the using method of solar water heater, exhaust overflow is not established on the top of heat-insulating water tanks, hot water outlet and moisturizing import are separately arranged separately, hot water outlet is arranged on the top of heat-insulating water tanks, moisturizing import is arranged on the bottom of heat-insulating water tanks opposite side, in the outside of heat-insulating water tanks, fluid level control valve of the present invention is installed and carries out automatic water supplement, when there being people to use solar water, tap water carries out instant moisturizing by fluid level control valve to heat-insulating water tanks, solar water heater output hot water and automatic water supplement are operated do not interfere with each other, achieve the synchronous water supplementing method that limit goes out the moisturizing of hot water limit, make that user is round-the-clock can use hot water, also need not worry that the water of solar water heater can be finished.Water hot water outlet is arranged on the top of heat-insulating water tanks, more meets the natural law, because can rise after heating up, in heat-insulating water tanks, hot water is collected at top, and the water must not waiting in heat-insulating water tanks all heats just has hot water to export, thus hot water effluent's speed is accelerated; After supplementing water enters heat-insulating water tanks, be trapped in the bottom of heat-insulating water tanks, heated at any time when there being sunlight, improve solar water heater efficiency, overcome the shortcoming that current solar water heater can not carry out moisturizing and not have again hot water to use when heat-insulating water tanks carries out moisturizing heat-insulating water tanks when user uses hot water, also overcome simultaneously and have water to flow out the shortcoming causing water resource waste from overflow after the water of heat-insulating water tanks fills.
The invention has the beneficial effects as follows: the built-in valve of tandem of design and fluid level control valve, be adapted at solar water heater, the water tank of central heating system, the water tower of industrial and mining enterprise, fire-water pond and boiler replenishing water case are applied.When applying at solar water heater, automatic synchronization moisturizing during use solar water, exports hot water and moisturizing does not interfere with each other, when moisturizing, user still normally can use hot water, makes people can use solar water heater more easily, save the time of people, and avoid waste water resource.Current or the hydraulic pressure direction of valve plate closing direction of the present invention and tap water are identical, utilize the pressure of tap water that valve plate is closed tighter, thus overcome the shortcoming that usual fluid level control valve is not closed completely.
