Abstract
The invention discloses a solar automatic control valve. The solar automatic control valve comprises a valve body (4), a water inlet (1), a water outlet (12), a valve plate (2) and a valve rod (5) which are arranged on the valve body (1), wherein the valve rod (5) is connected with a driving mechanism controlled by solar energy; the driving mechanism comprises a hydraulic cylinder (6); a piston (8) of the hydraulic cylinder is connected with the valve rod (5); and the upper end of the hydraulic cylinder (6) is provided with an air inlet and exhaust port (7), and an oil feeding pipe at the lower end of the hydraulic cylinder (6) is connected with an oil-ammonia tank (10). The solar automatic control valve is reasonable in design, simple in structure, good in control effect and reliable in operation and can realize synchronous working with a solar water heater.
Description
Technical field
The present invention relates to the device that a kind of controlling liquid flows, particularly a kind of solar energy autocontrol valve that utilizes solar energy control, it is than being more suitable for controlling solar water heater.
Background technique
Solar water heater generally comprises heat collector, the intake pipe, the outlet pipe that are connected with the heat collecting pipe of distribution in the heat collector and the hot water tank that is connected with outlet pipe, and hot water tank has reflow pipe to connect heat collector.During use, cold water gets into from intake pipe, behind the heat collecting pipe that in heat collector, distributes, comes out to get into hot water tank from outlet pipe, and the water in the hot water tank is back to heat collector, and the circulation heating is to improve water temperature.Owing to do not have valve to be connected between heat collector and the hot water tank.Night and the overcast and rainy heat loss shortcoming problem that exists.Especially, burning sun is fine, rains suddenly.Heat collector is caught in the rain, cooling suddenly, and the water temperature in the heat collector also descends thereupon; Cause the water counter-rotating reverse circulation in the heat collector, i.e. water in the heat collector flows to the bottom of hot water tank from the bottom; Flow back to the top of heat collector again from the top of hot water tank; This reverse circulation is because the water temperature of heat collector is low, this phenomenon of the big formation of density, and thermal loss is very big, causes the original hot water in the hot water tank to become cold water gradually.
Summary of the invention
The purpose of this invention is to provide a kind of solar energy autocontrol valve, it is simple in structure, and is reliable, controls effectively, can realize synchronousing working with solar water heater.
The object of the invention can be realized through following technical measures: a kind of solar energy autocontrol valve comprises that water intake, water outlet, valve plate, the valve rod of valve body, valve body, valve rod are connected with a driving mechanism through solar energy control.
Described driving mechanism comprises oil hydraulic cylinder, and the piston of oil hydraulic cylinder connects with valve rod, is set with Returnning spring on the valve rod, and the oil hydraulic cylinder upper end has porting, the oil inlet pipe of lower end to be connected with oily ammonia jar.
The present invention is reasonable in design, owing to driving mechanism is controlled by solar energy, when solar radiation is arranged; The temperature of the ammonia in the oil ammonia jar pressure that produces that raises passes to oil hydraulic cylinder through the hydraulic oil in the oily ammonia jar, after the piston stress in the oil hydraulic cylinder, with the valve rod ejection that makes progress; Valve plate upwards draws and activates to open, and after night, overcast and rainy arrival, temperature reduces; Ammonia volume-diminished in the oil ammonia jar, the piston stress in the oil hydraulic cylinder is little, through Returnning spring valve plate is closed.The present invention is simple in structure, controls effectively, reliable, can realize synchronousing working with solar water heater.
Description of drawings
Fig. 1 is a structural drawing of the present invention;
Fig. 2 is user mode figure of the present invention.
Embodiment
With reference to Fig. 1, a kind of solar energy autocontrol valve comprises water intake 1, water outlet 12, valve plate 2, the valve rod 5 of valve body 4, valve body; Valve rod 5 is connected with a driving mechanism through solar energy control, and driving mechanism comprises oil hydraulic cylinder 6, and piston 8 bottoms of oil hydraulic cylinder connect with valve rod 5; Be set with Returnning spring 3 on the valve rod 5, there is porting 7 oil hydraulic cylinder 6 upper ends, and the oil inlet pipe 11 of lower end is connected with oily ammonia jar 10; The material feeding mouth 9 of hydraulic oil and ammonia is arranged on the oil ammonia jar 10, can hydraulic oil and ammonia be joined 10 li in oily ammonia jar respectively, because the ratio of hydraulic oil is great through material feeding mouth 9; Therefore hydraulic oil is in oily ammonia jar bottom, and ammonia is on hydraulic oil.
Its working principle is: when solar radiation was arranged, the temperature of the ammonia in the oily ammonia jar raise, volumetric expansion; The pressure that produces passes to piston 8 through the hydraulic oil in the oily ammonia jar 10; Piston 8 moves up, because there is porting 7 oil hydraulic cylinder 6 upper ends, can easily valve rod 5 upwards be pushed away; Open valve plate 2, see Fig. 2; And after night, overcast and rainy arrival, temperature reduces, the ammonia volume-diminished in the oily ammonia jar, and the piston stress in the oil hydraulic cylinder is little, through Returnning spring 3 valve plate 2 is closed, and sees Fig. 1.
Below only with a mode of execution mentality of designing of the present invention is described, under the situation that system allows, the present invention can expand to external more function module simultaneously, thereby expands its function to greatest extent.
The above is merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
