Description
Technical field:
The utility model relates to a kind of solar water heater water overflow prevention device.
Background technology:
Solar water heater is the energy-conserving and environment-protective product that country supports energetically, its market prospects are boundless, more and more popular to people, and solar water heater must be installed in outdoor sun-drenched place, be connected to indoor use by pipeline, its control of supplying water mainly contains following dual mode:
First kind of mode is Artificial Control: this mode needs the two-way pipeline, and one the tunnel is the Inlet and outlet water common-use tunnel, and the upper end connects solar water heater water-storage storehouse lower port, and the lower end connects running water pipe and hot water tap respectively by transfer valve; Another road pipeline is a return pipe, and the upper end connects the water return outlet or the evacuation port of upper end, solar water heater water-storage storehouse, and the lower end is placed near the easy observed place of transfer valve.Transfer valve switches to be connected with running water and carries out water filling when needs add water, will ask for help simultaneously and observe return pipe at the scene, and return pipe there are flowing out when water was filled with, and at this moment closed running water immediately.And people in use tend to forget and in time close running water, have so not only made troubles to people but also cause the great amount of water resources waste.
Another kind of mode is to install water-level probe in solar water heater water tank additional, install electric control valve additional at the running water water inlet, control electric control valve by water-level probe, so this method needs material cost height such as electric wire, electrically-controlled valve, probe, the fault rate height, the I﹠M trouble, and owing to need electric energy, therefore need certain operating cost, so be difficult to promote.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of solar water heater water overflow prevention device, and it not only can in time automatically close water inlet when solar water heater is filled with water, avoid water resource waste.And cost is very low, no operating cost, advantages such as I﹠M convenience.
The utility model technical solution problem adopts following technical scheme:
Solar water heater water overflow prevention device is provided with the uncovered container of bottom closed upper end, in the bottom of described container water inlet is set, and the middle and lower part of container is provided with delivery port, and top is provided with water return outlet; Container inner wall between described water inlet and delivery port is provided with lower clapboard, container inner wall between described delivery port and water return outlet is provided with upper spacer, intracavity bottom at described container is provided with valve block, be provided with floating block in the container above described water return outlet, described floating block is connected with connecting rod with described valve block, and being provided with between described connecting rod and the described lower clapboard can be by the valve port of described valve block shutoff; Described delivery port is connected in the bottom of solar water heater storage water tank and concordant with the lowest water level of storage tank, and described water return outlet is connected in the top of storage tank.
The bottom of described floating block is concordant with the peak level of described storage tank.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1. solar water heater storage water tank can in time be closed water inlet when water is filled with, and avoids water to overflow and causes water resource waste.
2. low cost of manufacture does not need controlling electric energy, no operating cost.
3. I﹠M is convenient.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 container, 2 water inlets, 3 delivery ports, 4 water return outlets, 5 lower clapboards, 6 upper spacers, 7 valve blocks, 8 floating blocks, 9 connecting rods, 10 valve ports, 11 storage tanks.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment:
Embodiment: referring to Fig. 1, the solar water heater water overflow prevention device of present embodiment, the uncovered container of bottom closed upper end 1 is set, in the bottom of container 1 water inlet 2 is set, this water inlet is connected on the original water inlet pipe and water outlet pipe of solar water heater, and the middle and lower part of container 1 is provided with delivery port 3, and top is provided with water return outlet 4, described delivery port 3 is connected in the bottom of solar water heater storage water tank 11 and concordant with the lowest water level of storage tank, and described water return outlet 4 is connected in the top of storage tank 11.Container inner wall between described water inlet 2 and delivery port 3 is provided with lower clapboard 5, container inner wall between described delivery port 3 and water return outlet 4 is provided with upper spacer 6, intracavity bottom at described container 1 is provided with valve block 7, be provided with floating block 8 in the container above described water return outlet, described floating block 8 is connected with described valve block 7 usefulness connecting rods 9, connecting rod can adopt stiff rod or backguy, being provided with between described connecting rod 9 and the described lower clapboard 5 can be by the valve port 10 of described valve block 7 shutoff, and the bottom of described floating block 8 is concordant with the peak level of described storage tank 11.
In the use, valve block 7 selects density to make greater than the material of the density of water, floating block 8 selects density to make less than the material of the density of water, when needs in storage tank 11 during water filling, open switch tap make running water by pipeline from water inlet 2 water filling in container, water in the container is by delivery port 3 water filling in storage tank 11, this moment, valve block 7 was owing to the reason of deadweight still sinks to the bottom, rising along with water level in the storage tank 11, when the water in the storage tank 11 is filled with, storage tank 11 makes floating block 8 float and spurs valve block 7 risings to block valve port 10 that water inlet stops by container water return outlet 4 water filling in the container of upper spacer 6 tops.When the user need use hot water, produce negative pressure in the container of valve block 7 belows, negative pressure is greater than the buoyancy of 8 pairs of valve blocks of floating block, valve block 7 sinking valve ports 10 are opened, hot water in the storage tank 11 refluxes through water outlet of container 3, water inlet 2, and along with the reduction of water level in the storage tank 11, the buoyancy of floating block 8 disappears, valve block 7 and floating block return initial position, for next water filling is got ready.
