Abstract
The invention relates to a water closer which automatically closes when the water of a solar water heater is full. The problem needing to be solved is to overcome the defect that the existing solar water heater can not automatically close the water. The invention is characterized in that a quick-opening valve with a lower resistance is arranged on the water inlet pipe of the water heater. A valve spring and a handle rod are arranged on the valve with a lower resistance. A cylindrical bolt is arranged on the location corresponding to the handle rod by 90 degrees; the lower end of the cylindrical bolt is connected with a labor saving lever formed by a working board. The lower part of the working board is provided with a pressure capsule and a tee. The tee is connected with a return pipe and an emptying pipe. The water closer has the advantages of reasonable design, simple structure and convenient maintenance. The sensitivity for closing water is high; a switch is touched when less water returns. The water closer is safely and reliably used.
Description
Technical field

Background technique
Solar water heater has obtained using widely in daily life.Prior solar water heater is employed when moisturizing to be the ball valve switch, adds the wait that water needs certain hour.Sometimes the user forgets Guan Shui, causes " water overflow Kingsoft ", causes great water resource waste.Adopt the float-ball type water controller to be immersed in for a long time in the hot water because of its parts, reliability is very poor, so gradually eliminated.And adopt the electronic type water controller because of cost height, dangerous very difficult popularization.
Summary of the invention
Content of the present invention is: overcome the shortcoming of existing water-supply valve of solar water heater, for the user provides a kind of reliable, safe, practical solar energy automatic water-closing device.
Realize that foregoing invention purpose design proposal is such.
Auto-closing device for solar water heater, comprise the valve that is installed on the heater inleting pipe, it is characterized in that: described valve is lower resistance, quick opening valve, its angle of rotation is 90 degree. lower resistance valve 8 is provided with column valve rod 1, column valve rod 1 can rotate with valve switch, column valve rod 1 is provided with handlebar 5, suit valve spring 3 on the column valve rod on handlebar 5 tops; The lower resistance valve is installed on the valve shell 2.On the right side of valve shell 2, be 90 degree corresponding parts with handlebar 5 lock bolt sleeve 7 is installed, be provided with columnar lock tongue 6 in the lock bolt sleeve 7, there is Returnning spring 9 columnar lock tongue 6 lower ends, and Returnning spring base 10 is equipped with in Returnning spring 9 lower ends.Center, columnar lock tongue 6 lower end links to each other with connecting rod 12, and connecting rod 12 passes Returnning spring 9 and base 10 thereof.The connecting rod of spring pedestal 10 lower ends is equipped with location card 11; The below of lower resistance valve 8 is provided with working plate 15, and the both sides of working plate 15 are provided with positioning shaft 13, and positioning shaft 13 passes the valve casing corresponding part.The lower end of connecting rod 12 curves in the working hole 14 of front end that the right angle is inserted in working plate 15; Close-connected with the working plate lower end is Pressure capsule 16, Pressure capsule 16 upper end closeds, and lower ending opening also is connected with threeway 19.Threeway 19 connects return pipe 17 and emptying pipe 18 successively.
The present invention has the advantage of the following aspects:
1. the present invention is reasonable in design, and is simple in structure, easy to maintenance.
2. bright and beautiful sensitivity height is closed in the present invention, and a small amount of backwater is trigger switch just.
3. safety of the present invention, reliable.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention
Accompanying drawing 2 is working plate and Pressure capsule and connecting rod position relation.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described by embodiment
Auto-closing device for solar water heater comprises the valve that is installed on the heater inleting pipe, it is characterized in that: described valve is lower resistance, quick opening valve, its angle of rotation is 90 degree. lower resistance valve 8 is provided with column valve rod 1, column valve rod 1 can rotate with valve switch, column valve rod 1 is provided with handlebar 5, suit valve spring 3 on the column valve rod on handlebar 5 tops; The lower resistance valve is installed on the valve shell 2.On the right side of valve shell 2, be 90 degree corresponding parts with handlebar 5 lock bolt sleeve 7 is installed, be provided with columnar lock tongue 6 in the lock bolt sleeve 7, there is Returnning spring 9 columnar lock tongue 6 lower ends, and Returnning spring base 10 is equipped with in Returnning spring 9 lower ends.Center, columnar lock tongue 6 lower end links to each other with connecting rod 12, and connecting rod 12 passes Returnning spring 9 and base 10 thereof.The connecting rod of spring pedestal 10 lower ends is equipped with location card 11; The below of lower resistance valve 8 is provided with working plate 15, and the both sides of working plate 15 are provided with positioning shaft 13, and positioning shaft 13 passes the valve casing corresponding part.The lower end of connecting rod 12 curves in the working hole 14 of front end that the right angle is inserted in working plate 15; Close-connected with the working plate lower end is Pressure capsule 16, Pressure capsule 16 upper end closeds, and lower ending opening also is connected with threeway 19.Threeway 19 connects return pipe 17 and emptying pipe 18 successively.
When solar water heater need add water, handlebar 5 nine ten degree that turn right, valve spring 3 has just stored elastic potential energy.Simultaneously, handlebar 5 promotes dead bolt 6 and moves down, and handlebar 5 is crossed dead bolt 6, and dead bolt 6 rises under Returnning spring 9 effects, and dead bolt 6 has stoped the resilience of handlebar 5, and valve 8 is opened, and begins to solar water heater watering.
After the solar water heater water tank topped up with water, unnecessary water just overflows from return pipe 17 and is pressed in the Pressure capsule 16, Pressure capsule 16 pressed volume expand, and the rear end of working plate 15 is upwards risen, and working plate 15 is a laborsaving lever, so the working plate front end moves downward, pulling connecting rod 12 also makes dead bolt 6 move downward, and has removed the retaining power of handlebar 5 like this, at this moment, the elastic potential energy that valve spring 3 stores just is released, and valve 8 returns to the state of pass under the elastic force effect of valve spring 3.Realized that solar water heater closes automatically after water is filled it up with.After the water route was closed, emptying pipe was gently discharged all backwater in the return pipe, and is ready for close water next time.
