Abstract
Disclosed is an automatic full-water cutoff valve. A rotation switch is disposed inside a valve body of the automatic full-water cutoff valve, a valve shaft of the cutoff valve is fixedly connected with a valve shaft of a water feeding valve of a water heater, and a water inlet connector of the cutoff valve is communicated with an overflow pipe of the water heater. When water is fully fed, water in the water heater flows into the automatic full-water cutoff valve through the overflow pipe, the rotation switch, which is under pressure of the water inside the overflow pipe, in the valve body drives a valve shaft of the water feeding valve of the water heater to rotate, and accordingly, the purpose of automatically closing the water feeding valve when the water is fully fed is achieved.
Description
Technical field
The utility model relates to the device of closing automatically when water is full on a kind of solar water heater.
Background technique
At present, the known method of the full self-closing device of solar water heater water is, a secondary water tank is set above water-heater water tank, has an interface to be connected with water-heater water tank on the secondary water tank, in the secondary water tank ball float controlling switch is arranged, ball float controlling switch links to each other with the water inlet of water heater.When in the water tank during filling up water, the water in the water-heater water tank has promptly entered in the secondary water tank, and the ball float in the secondary water tank is subjected to buoyancy and drives ball float controlling switch and rotate, and makes ball float controlling switch close the current in the water inlet, thereby reaches the purpose that water is closed completely automatically.But, because secondary water tank is in the water heater top, so usually reach very high temperature in the secondary water tank, make the jointing of ball float controlling switch and water inlet usually have very thick incrustation scale, when containing other impurity in the water, just easier obstruction filling pipe end makes water heater can not enter water.
Summary of the invention
In order to overcome the deficiency that the full self acting stop valve of existing water stops up filling pipe end easily, the utility model provides a kind of water full self acting stop valve, and the full self acting stop valve of this water can be realized the full automatic closing function of water easily.
The technological scheme that its technical problem that solves the utility model adopts is: the arc-shaped cavity that two connections are arranged in the valve body of the full self acting stop valve of water, one is the blade arc cavity, another is the valve shaft arc-shaped cavity, the valve shaft of the full self acting stop valve of water and valve shaft arc-shaped cavity form and are sealed and matched, there is a curved blade to be cemented on the valve shaft, and blade and blade arc cavity form and are sealed and matched, one water inlet interface and water outlet interface is arranged, and water inlet interface and water outlet interface are connected with the blade arc cavity respectively on valve body.When the full self acting stop valve of water was installed on the water heater, the valve shaft that makes the full self acting stop valve of water was connected with the valve shaft of the water supply valve of water heater, and the water completely water inlet interface of self acting stop valve is connected with the spill pipe of water heater.
The beneficial effects of the utility model are: because this valve is installed in indoorly, suffered externally temperature influence is little, and simple in structure, can realize stably that water closes completely automatically.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the utility model is installed in the schematic representation on the solar water heater.
Fig. 2 is a sectional view of the present utility model.
1. internal water tanks among the figure, 2. turnover water pipe, 3. spill pipe, 4. relief opening, 5. discharging valve, 6. water supply valve, the 7. full self acting stop valve of water, 8. valve body, 9. valve shaft, 10. blade, 11. blade arc cavitys, 12. valve shaft arc-shaped cavities, 13. water inlet interfaces, 14. water outlet interfaces.
Embodiment
Fig. 1 is installed in embodiment on the solar water heater for the full self acting stop valve of water, in Fig. 1, turnover water pipe 2 one ends are communicated with discharging valve 5 and water supply valve 6, the other end is communicated with water heater internal water tank 1, relief opening 4 on the internal water tank 1 is connected with spill pipe 3, the valve shaft 9 of the full self acting stop valve 7 of water is connected with spill pipe 3 with the valve shaft concrete mutually of water supply valve 6, the water inlet interface 13 of the full self acting stop valve 7 of water.
Among Fig. 2, there are two arc-shaped cavities to be respectively blade arc cavity 11 and valve shaft arc-shaped cavity 12 in the valve body 8 of the full self acting stop valve 7 of water, the valve shaft 9 of the full self acting stop valve 7 of water forms with valve shaft arc-shaped cavity 12 and is sealed and matched, blade 10 is cemented on the valve shaft 9, and blade 10 forms with blade arc cavity 11 and is sealed and matched, into water interface 13 and water outlet interface 14 are arranged, and water inlet interface 13 and water outlet interface 14 are connected with blade arc cavity 11 respectively on valve body 8.This device realizes that the principle of closing automatically is, when waterborne the expiring in the solar water heater internal water tank 1, water promptly enters in the spill pipe 3 by relief opening 4, water enters in the blade arc cavity 11 by the water inlet interface 13 of the full self acting stop valve 7 of water under action of gravity, blade 10 drives valve shaft 9 and rotates under the action of gravity of water, and the valve shaft of valve shaft 9 and water supply valve 6 is connected, thereby closes water supply valve 6, reaches the purpose of closing automatically when water is expired.
Claims (1)
1. a water is expired self acting stop valve, it is characterized in that: the arc-shaped cavity that two connections are arranged in its valve body, be respectively blade arc cavity and valve shaft arc-shaped cavity, the valve shaft of the full self acting stop valve of water and valve shaft arc-shaped cavity form and are sealed and matched, one curved blade is cemented on the valve shaft, and blade and blade arc cavity form and are sealed and matched, and a water inlet interface and a water outlet interface is arranged on valve body, and water inlet interface and water outlet interface are connected with the blade arc cavity respectively.
