Abstract
The utility model relates to a solar water heater gravity automatic closing device, comprising a valve installed on a water-feed pipe. The solar water heater gravity automatic closing device is characterized in that a handle is connected on the valve handle of the valve, and the end section of the handle is tilting, and the included angle of the end section and the fore section of the handle is 140-165 degrees. The end of the handle is connected with a container in which is inserted with the overflow pipe of the solar energy water heater. When the solar energy water heater is needed to feed water, the handle is made to in the water supply state. When the water is full, superfluous water pours from the overflow pipe into the container. A handle for feeding cold water is driven to automatically turn to the inactive state until complete closure along with the increase of the water quantity in the container, and then the solar energy water heater automatically stops to feed water. The inner structure of the existing valve is not altered by the utility model, a straight handle is not adopted by the handle, but a bended handle with a folding angle is adopted, and the water quantity overflowed in the water tank of the solar water heater can be diminished, thus the purpose of water saving is achieved. The bended handle is favorable for installing.
Description
Technical field
The utility model belongs to the control valve field, and the weight that water is overflowed in particularly a kind of utilization is closed the device of water on the solar water heater automatically.
Background technology
Widely used mixed water valve has characteristics easy to use on the solar water heater at present, and mixed water valve is connected on the water supply pipeline, and is connected with the water tank connecting pipe road of solar water heater, also is connected with shower nozzle.Water is gone up in last cold water handle control or water is closed in the pass, and the temperature adjustment handle can be regulated the water yield of shower nozzle can regulate water temperature again.
Utilize overflow pipe to show the solar water heater whether water in the water tank is filled with, closing of water supply valve door relies on manual operations.On solar energy during water people can not away from, otherwise after filling with water, water flows out along overflow pipe, not only wastes water, and can make troubles to the user.And because manual valve-off in the zone of Timing water supply, uses very inconvenience.For this reason, people have also designed the mode of some automatic-closing valves, but all are unfavorable for promoting the use of.Chinese patent, application number is 02212899 to disclose water valve-closing device on a kind of solar water heater, disclosed the technical scheme of closing that the weight of utilizing the water that overflow pipe flows out is come by-pass valve control, the operating grip of valve (straight hand lever) connects a container by rope, and overflow pipe connects container.But at present the valve switch direction of using almost is orthogonal angle entirely, and with body of wall fixedly the time, its direction or be that horizontal direction is opened, and downward 90 degree close, or upwards 90 degree are opened, the horizontal direction pass.So on the basis that is not changing existing valve mechanism, could valve-off when the water in the container must reach a certain amount of, because, near closed condition, the rotary arm of handle is more and more littler more, and the power that needs must be increasing, so need the water of more amount, do not reach the purpose of water saving like this.In the horizontal direction for opening, downward 90 degree are example for closing with handle, and in off position, rope is very near from body of wall, is unfavorable for the placement of container, thereby influences closed condition.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of solar water heater gravity self closing device of water saving.
A kind of solar water heater gravity self closing device of the present utility model, comprise the valve that is installed on the upper hose, it is characterized in that connecting one handle on the valve handle of described valve, the latter end of handle is skewed, angle between handle latter end and the leading portion is the 140-165 degree, the end of handle connects a container, inserts the solar water heater overflow pipe in the container.
The utility model does not change the internal structure of existing valve, only needs increase handle on former valve handle for the valve of having installed and used, and the mixed water valve of later production its valve handle that only need extend is got final product.Handle does not adopt straight hand lever, adopts the bending of the hand handle, increases rotary arm, can reduce downward strength when mixed water valve cuts out, and promptly reduces the consumption of water in the container yet, reduces the water yield of overflowing in the solar water heater water tank, thereby reaches water-saving purpose.
The preferably preceding segment length of the length of described handle is 5-7cm, and latter end length is 3-4cm.
Valve of the present utility model preferably adopts the widely used mixed water valve of prior art.
Advantage of the present utility model:
Only need open valve switch during water on the solar water heater and get final product, fill water after, the water that flows out from overflow pipe enters valve is closed automatically, and is time saving and energy saving, using water wisely, and be convenient to install.The utility model also can be fit to other filling apparatus of taking back the stream device.

The specific embodiment
As Fig. 1, the following pipe joint that mixes water valve 1 is connected with running water upper hose 10, top pipe joint is connected with solar water heater inlet pipe 4, the pipe joint on the right side is connected with shower nozzle 9, and the last cold water handle 2 on the left side is a knuckle bending of the hand handle, and preceding segment length is 5-7cm, latter end length is 3-4cm, angle between leading portion and the latter end is the 140-165 degree, is preferably 150 degree (angle between handle leading portion and the latter end both can be the knuckle shape, also can be the bent angle that seamlessly transits).The end of last cold water handle 2 connects water container 6 by rope 7, and the overflow pipe 5 of solar water heater inserts in container 6.
When last cold water handle 2 horizontal directions of mixing water valve for open, when downward 90 degree are the pass, Fig. 2 is the water supply state, Fig. 3 is a closed condition.
When last cold water handle 2 horizontal directions of mixing water valve for closing, upwards 90 spending when opening, Fig. 4 is the water supply state, Fig. 5 is a closed condition.
When solar water heater need be gone up water, make cold water handle 2 be the water supply state, behind filling up water, from overflow pipe 5, flow out unnecessary water and enter container 6, along with increasing of the water yield in the container, the cold water handle rotates from the trend closed condition in the drive, and until closing fully, solar water heater stops to go up water automatically.The temperature adjustment handle 8 (also claiming the automatic water-mixing handle) that mixes water valve 1 uses according to the mode of prior art, as Fig. 1, when having a bath, when needing regulating pondage, pulls temperature adjustment handle 8 up and down, and the water yield increases when upwards pulling, and the water yield reduces when pulling downwards.When needing to regulate water temperature, left rotation and right rotation temperature adjustment handle 8, to the first from left sideway swivel, water temperature raises, a sideway swivel to the right, water temperature descends.
