Abstract
The invention relates to a hydrostatic water-full automatic cut-off valve used to automatically cut off water feed of solar water heater. A rotary switch is arranged in a valve body. The valve shaft of the automatic cut-off valve is fixedly connected with the water feed valve of the water heater. The water inlet interface of the automatic cut-off valve is communicated with the overflow pipe of the water heater. When water is full, the water in the water heater flows into the hydrostatic water-full automatic cut-off valve through the overflow pipe, the rotary switch in the valve body drives the valve shaft of the water feed valve of the water heater to rotate under the pressure of the water in the overflow pipe, and thereby the water feed valve is automatically cut off when water is full.
Description
Technical field
The present invention relates to the device that water on a kind of solar water heater is closed when full automatically.
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 invention provides a kind of hydrostatic water-full automatic cut-off valve, this hydrostatic water-full automatic cut-off valve can be realized the full automatic closing function of water easily.
The technical solution adopted for the present invention to solve the technical problems is: the arc-shaped cavity that two connections are arranged in the valve body of hydrostatic water-full automatic cut-off valve, 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 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 hydrostatic water-full automatic cut-off valve is installed on the water heater, the valve shaft of the water supply valve of the valve shaft of hydrostatic water-full automatic cut-off valve and water heater is connected, the water inlet interface of hydrostatic water-full automatic cut-off valve is connected with the spill pipe of water heater.
The invention has the beneficial effects as follows: 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
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is that the present invention is installed in the schematic representation on the solar water heater.
Fig. 2 is the A-A sectional view of hydrostatic water-full automatic cut-off valve among Fig. 1.
1. internal water tanks among the figure, 2. turnover water pipe, 3. spill pipe, 4. relief opening, 5. discharging valve, 6. water supply valve, 7. hydrostatic water-full automatic cut-off valve, 8. valve body, 9. valve shaft, 10. blade, 11. the blade arc cavity, 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 hydrostatic water-full automatic cut-off valve, 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 hydrostatic water-full automatic cut-off valve 7 and the valve shaft concrete mutually of water supply valve 6, the water inlet interface 13 of hydrostatic water-full automatic cut-off valve 7 is connected with spill pipe 3.
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 hydrostatic water-full automatic cut-off valve 7, 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 water inlet interface 13 by hydrostatic water-full automatic cut-off valve 7 under action of gravity enters in the blade arc cavity 11, 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. hydrostatic water-full automatic cut-off 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 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.
