Number in the figure: 1 storage tank, 2 overflow pipes, 3U shape pipe, 31U shape is managed first end, and 32U shape is managed second end, 4 outlet pipes, 5 floats, 6 levers, 7 pouring weights, 8 water inlet pipes, 9 water supply valves, 91 switch levers, 10 check valves.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the spilling water that the is used for solar water heater device of cutting off the water automatically, the sidewall upper of the storage tank 1 of solar water heater is provided with overflow pipe 2, the water inlet pipe 8 of storage tank 1 is provided with water supply valve 9, the spool of water supply valve 9 is fixedlyed connected with first end of the switch lever 91 of water supply valve 9, switch lever 91 is used to control spool opening/closing water supply valve 9, the delivery port that it is characterized in that overflow pipe 2 connects U-shaped pipe first end 31, be provided with float 5 in the body of U-shaped pipe second end 32, be connected with outlet pipe 4 on the sidewall of the body of U-shaped pipe second end 32; Second end of switch lever 91 is connected with pouring weight 7; Pouring weight 7 is connected with first end of lever 6; When pouring weight 7 and lever 6 were in first duty, second end of lever 6 was taken on the mouth of pipe that is against U-shaped pipe second end 32, and water supply valve 9 is in open mode; When pouring weight 7 and lever 6 were in second duty, second end of lever 6 left the mouth of pipe of U-shaped pipe second end 32, and water supply valve 9 is in closed condition; Float 5 is used for when storage tank 1 spilling water, and second end of jack-up lever 6 also drives pouring weight 7, makes lever 6 and pouring weight 7 change to second duty from first duty.The deviation of gravity center of pouring weight is in pouring weight 7 connecting portion with switch lever 91 second ends, and meaning is that the center of gravity of pouring weight 7 is not on the connecting portion of second end of switch lever 91 and pouring weight 7.Second end of switch lever 91 is prismatic, and pouring weight 7 is provided with prismatic hole, and the prism end of switch lever 91 is plugged in the prismatic hole, and after prismatic end inserted prismatic hole, this prism end can not rotate with respect to prismatic hole in prismatic hole.Pouring weight 7 is a trapezoid block, and when first duty, trapezoid block is in inversion state; When trapezoid block was in inversion state, the little head end of trapezoid block down; Prismatic hole is arranged at little head end one side of trapezoid block, and on the cross section of trapezoid block, cross section, prismatic hole is a polygon, and polygonal center of gravity is positioned on the perpendicular bisector on trapezoidal base.Float 5 is the hollow cylinder pipe of closed at both ends.Also be provided with check valve 10 on the water inlet pipe 8.
During concrete enforcement, water supply valve is selected type hand water valve commonly used, and spool is connected with switch lever, by rotating switch bar control spool, realizes the opening and closing of valve.Pouring weight is selected iron block for use, and lever is selected iron for use, and lever and iron block weld together.The preferred non-equilateral triangle of the cross sectional shape of the prism end of switch lever, the cross section in the prismatic hole on the corresponding pouring weight also is preferably similar non-equilateral triangle, when this triangular styletable and this tri-prism hole are pegged graft thus, has only a kind of inserting mode, during with the assurance valve open, lever can be taken on the mouth of pipe that is against U-shaped pipe second end just.Float is the hollow cylinder pipe of closed at both ends, preferred hollow lucite tube.
After the user opened water supply valve, when the water level in the storage tank was increased to overflow pipe gradually, water flowed out from the delivery port of overflow pipe, and injects the U-shaped pipe from U-shaped pipe first end.According to law of connected vessels, the water level at U-shaped pipe two ends will be maintained at the same horizontal plane.The cylindrical float that U-shaped pipe second end is provided with, owing to buoyancy of water and pressure rise, the float that rises is against jack-up taking on the lever of the mouth of pipe, lever second end lifts, the pouring weight of fixedlying connected with lever first end rotates and centre-of gravity shift, then pouring weight is being rotated further under the effect of gravity, and lever and pouring weight are changed to second duty from first duty, thereby water supply valve is closed.Pouring weight after the rotation can not changed to second duty from first duty automatically owing to the effect of deadweight.The utility model adopts common components such as U-shaped pipe, float, pouring weight, and electrical equipment is not set, and is not subjected to electrical power limit, have simple in structure, cost is low, advantage such as easy to operate, safe in utilization.Because of pouring weight can not automatically revert to first duty when second duty, therefore water supply valve is closed back being opened just by the user and can be gone up water once more, the last water time is controlled voluntarily by the user, has solved the problem that adds cold water automatically after the storage tank middle water level descends and reduce water temperature.Check valve on the water inlet pipe can avoid the hot water in the storage tank to be back in the water inlet pipe.
The utility model is particularly useful for solar water heater, also can be used for the device that other need be cut off the water automatically and manually water is gone up in control.
