Abstract

The utility model relates to a water-saving type automatic switch. A partition plate is arranged in the shell; a water hole is opened on the partition plate, and the bottom of the shell is provided with a drainage opening; a water feeding branch pipe penetrates through an upper cavity of the shell; a floater valve is connected to the water feeding branch pipe; an external lower interface of the water feeding branch pipe is connected with a tee joint; an elastic ball is installed in a lower cavity of the shell; and a lower pipe opening of the elastic ball is connected with the tee joint after penetrating through a bottom plate of the shell. The utility model can realize the effect of automatically closing water feed after a solar water heater is full of water to achieve the aim of water saving and save the waiting time of the user and the material cost for installing the solar water heater.

Description

Water-saving automatic switch
Technical field
The utility model relates to a kind of switching device, specifically a kind of water-saving automatic switch.
Background technology
Freshwater resources are a kind of non-renewable resources, have occurred short water supply now.But also exist in some cases, the phenomenon of artificial waste water resource.As the solar water heater that generally uses at present, when last water, need by water completely after the flowing water of overflow pipe land and judge the water tank filling up water, this form is waste water resource both, sinks money again.In a single day if forget behind the last water and turn-off the water supply valve door, then waste is just bigger, more.
Summary of the invention
The purpose of this utility model just provides a kind of water-saving automatic switch, to solve solar water heater because of closing the problem of the untimely water resource waste that causes of water.
The utility model is achieved in that a kind of water-saving automatic switch, is provided with dividing plate in housing, has water hole on described dividing plate, has relief port in the bottom of described housing; Water arm on cross-under has in the upper chamber of described housing is connected to float-controlled valve on the water arm on described, and described outside lower interface and threeway of going up the water arm joined; In described lower part of frame cavity, resilient bladder is housed, after the lower nozzle of described resilient bladder passes the base plate of described housing, joins with described threeway.
The utility model utilizes the volumetric expansion after the resilient bladder water inlet to block water hole on the dividing plate when water filling, the backwater that overflows is just accumulated in the housing upper chamber when flowing into housing, thereby make the ball float action of float-controlled valve, closes automatically and closes the water arm.When water, utilize the water hole on the open dividing plate of volume retraction after the resilient bladder water outlet, the water in the housing upper chamber is flowed out by dividing plate and lower part of frame cavity, thereby make the ball float action of float-controlled valve, open the water arm, make the conducting of water arm.Realize the full automatic stop function of the water of solar water heater in last water process thus.
The utility model has top cover at the buckle closure suitable for reading of described housing, has exhaust outlet on described top cover, and the lower port cross-under of the overflow pipe of solar water heater is on described top cover.
Equipped solar water heater of the present utility model can automatically shut down water after water is full, reach water-saving purpose thus.In the process of water on solar water heater, the user needn't wait for that water initiatively closes water after completely, can freely work, thus the time of having saved the user.And, use after the utility model, can also shorten the overflow pipe of solar water heater greatly, thereby also save the material cost that solar water heater is installed for the user.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a resilient bladder 7 is housed in the lower cavity of housing 8, is fixed with dividing plate 6 at the middle part of housing 8.Dividing plate 6 is arc top spherical plate upwards preferably, has a water hole 11 in the centre of dividing plate 6.Have in the bottom of housing 8 centre bore and a bypass relief port 9---centre bore is used for the lower nozzle of cross-under resilient bladder 6, relief port 9 is used for the water of releasing and flowing down from the housing upper chamber.Horizontal water arm 5 in one of the cross-under in the upper chamber of housing 8 is connected to float-controlled valve 1 on last water arm 5, float-controlled valve 1 is arranged in the housing 8.The right-hand member of last water arm 5 passes housing 8, is used to connect the water inlet pipe of solar water heater; It is curved down that the left end of last water arm 5 passes housing 8 backs, and its outside lower interface joins with the threeway 10 that is arranged on housing 8 bottoms.After the lower nozzle of resilient bladder 7 passes the base plate of housing 8, join with the another port of threeway 10.The 3rd port (being downward port) of threeway 10 is used to connect from subscriber household and connects the upper hose that draws up.
The lower port of the overflow pipe 4 of solar water heater can be connected to the place suitable for reading of housing 8, certainly, for simplicity, can be at top cover 3 of buckle closure suitable for reading of housing 8, have exhaust outlet 2 and cross-under mouth on top cover 3, the lower port cross-under of the overflow pipe 4 of solar water heater also is fixed on this cross-under mouth.
During last water, the current in the upper hose flow in the water tank of solar water heaters by threeway 10 and last water arm 5, have the part current to enter in the resilient bladder 7 by threeway 10 simultaneously, make the volumetric expansion of resilient bladder 7, and the water hole on the dividing plate 6 11 is blocked.After water was filled with and overflowed, the current that overflow just flowed in the upper chamber of housing 8 by overflow pipe 4, and the ball float of float-controlled valve 1 is hiked up, and float-controlled valve turn-offs, and last water promptly is cut off.During water, water in the resilient bladder 7 flows out in advance, the volume retraction of resilient bladder 7, water hole 11 on the dividing plate 6 is open-minded, water in housing 8 upper chamber flows into lower cavity, and by 9 outflows of the relief port on the housing 8, this moment, float-controlled valve 1 promptly was opened, and the hot water in the solar water heater just can flow in user's the Household bathroom by last water arm 5, threeway 10 and upper hose.
