Abstract
The utility model discloses a water supply device for a solar water heater, which is controlled by a water tank and a float valve. The utility model is characterized in that the bottom of the water tank is provided with a water discharging valve which has the time-delay action. When the hot water in the water storage tank of the solar water heater is run out and the water is needed to be supplied, the water level in the water supply device slowly drops down because the diameter of the water discharging hole of the water discharging valve is 2 to 5 mm. Thus, the time of the opening of the supply float valve is delayed. Consequently, the defect of the existing solar water heater that the use is influenced by the instant fall of the water temperature because the tap water is suddenly added into the water storage tank can be avoided.
Description
The utility model relates to the solar water heater control device, especially a kind of solar water heater water-supply apparatus.
The water-supply apparatus of existing solar water heater has manually goes up two kinds of water and automatic loading waters.Manually water-supply apparatus needs special messenger's control, and is time-consuming.Because the last water opportunity and the last water yield are difficult to control, careless slightly, also can metal run out and cause waste.If forget and go up water, then influence is normal uses; And water is gone up in the control of automatic water-supply apparatus general using float valve, and when solar water heater water storage tank water level dropped to the water water level, float valve was opened, and running water enters the solar water heater water storage tank, and float valve cuts out after the water storage tank topped up with water, stops to go up water.But find that in use this automatic water-supply apparatus has its shortcoming, promptly when using solar water heater, because of water level in the water storage tank descends, float valve is opened water automatically, and cold water can add water storage tank immediately, and the interior water temperature of water storage tank is sharply descended and the normal use of influence.
The purpose of this utility model to provide exactly a kind of both can automatic loading water, the water storage tank water temperature is descended immediately and influence the solar water heater water-supply apparatus of normal use.
The solar water heater water-supply apparatus that designs for achieving the above object is made up of water tank, float valve and time-delay valve.The water tank upper of water-supply apparatus communicates with the overflow pipe of the water storage tank of solar water heater, and the bottom of water tank is provided with float valve and time-delay valve.The valve pocket of float valve communicates with water supply pipe and solar water heater water storage tank, and diameter is arranged at the time-delay valve top is that the vent of 2-5 millimeter communicates with water tank, vent can be blocked during buoyancy aid spool come-up in the valve pocket.
The operation principle of solar water heater water-supply apparatus of the present utility model is, when in the water tank of solar water heater water-supply apparatus when anhydrous, float valve is opened, and running water enters in the water storage tank of solar water heater by the float valve chamber.Water storage tank water completely back running water enters by overflow pipe in the water tank of water-supply apparatus, and the water level rising in the water tank makes the ball float come-up of float valve close float valve, stops to go up water.When using solar water heater, the buoyancy aid spool that the water storage tank water level drops in the time-delay valve valve pocket that makes water-supply apparatus descends, and vent just is opened, and the water in the water-supply apparatus water tank is flowed away through vent.Very little owing to water tank vent aperture, only be the 2-5 millimeter, water pouring speed is very slow, and this has just delayed opening the time of water-supply apparatus float valve, and cold water can not add in the solar water heater water storage tank immediately, makes water temperature decline suddenly and influence use in the water storage tank.After after a while, the water level in the water-supply apparatus water tank drops to the position that float valve is opened, and float valve is just opened, and automatic loading water is in order to using.
Because the vent of time-delay valve is very little, to be stopped up by foreign material easily, influence is used.Therefore the draw point that can to fix a diameter on the buoyancy aid spool in the time-delay valve valve pocket be vent diameter 1/2nd places vent.During last water, draw point can not stopped up vent by foreign material with buoyancy aid spool play up and down.
Embodiment is further described the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model solar water heater water-supply apparatus example structure schematic diagram.
As shown in Figure 1, the solar water heater water-supply apparatus is made up of the float valve 15 and the time-delay valve 11 of water tank 6 and band ball float 7.Water tank 6 tops communicate with the overflow pipe 4 of solar water heater water storage tank 3, water tank 6 tops also have exhaust outlet 5, water tank 6 bottoms are provided with the float valve 15 of band ball float 7, its valve pocket 1 communicates with the running water pipe 16 and the solar water heater inlet mouth of pipe 13, water tank 6 bottoms also have time-delay valve 11 to communicate with solar water heater water storage tank 3, time-delay valve 11 tops have the vent 8 of diameter 2-5 millimeter to communicate with the water tank 6 of water-supply apparatus, when floating, vent 8 can be blocked the buoyancy aid spool in time-delay valve 11 valve pockets, the draw point 9 that is fixed with a diameter on the buoyancy aid spool 10 and is vent 8 diameters 1/2nd is inserted in the vent, time-delay valve 11 valve pocket bottoms have backing pin 12 with buoyancy aid spool ball 10 retainings in time-delay valve 11 valve pockets.During last water, in the water storage tank 3 that the valve pocket 14 and the water inlet pipe 13 and 2 of running water by float valve 15 enters solar water heater.When solar water heater water storage tank 3 topped up with water, running water enters in the water tank 6 of water-supply apparatus by overflow pipe 4, ball float 7 floated when water level arrived certain position in the water tank 6 of water-supply apparatus, and float valve 15 disconnects running water pipe 16 and solar water heater inlet pipe 13, and last water finishes.When using solar water heater, the water in the water storage tank 3 of solar water heater is flowed out by water pipe 1.Buoyancy aid spool 10 falls in the time-delay valve 11 when water level in the solar water heater water storage tank 3 drops to, and when the water pouring valve was opened, water tank 6 water pourings of water-supply apparatus were because the diameter of vent 8 has only the 2-5 millimeter, so the water tank 6 water pouring speed of water-supply apparatus are very slow.When water uses up in the solar water heater water storage tank 3, water level does not drop to the position of opening float valve 15 yet in the water tank 6 of water-supply apparatus, running water just can not be immediately mend in the water storage tank 3 of solar water heater, after after a while, water level in the water tank 6 of water-supply apparatus could arrive the position of opening float valve 15, makes solar water heater begin to go up water.
