Abstract

The utility model relates to an automatic water feeder for a solar water heater. A draw rod (6) arranged in a casing (3) is arranged on a fixing plate (4) of an elastic rubber plate (2), and both ends of a lever (11) are respectively hinged on the draw rod (6) and a supporting shaft (7). The tail end of the lever is provided with a sealing block (8) positioned above the water inlet hole (9) of a water inlet pipe (10). The casing is also provided with a water outlet pipe (1), and a spring is arranged between the casing and the fixing plate. The automatic water feeder can automatically supplement water when a water tank lacks water and can automatically stop the water intake when the water tank is full, so the utility model saves the users' time and energy and eliminates the possibility of swelling the water tank to bad. The utility model has the advantages of simple structure and little space occupation and can be used for other fields.

Description

The automatic water controller of solar water heater

The utility model provides a kind of automatic watering apparatus.

At present, the water process that adds of solar water heater is to add water from upper hose to water tank.When the user such as has only at overflow pipe flowing water, can know that just water tank is full, to close the water supply valve door.As untimely valve-off, the possibility of the bad water tank that rises is arranged then.Like this, the user must keep a close eye on whether flowing water of overflow pipe when water tank is added water, wasted a lot of time and efforts.And more existing priming apparatus such as ball-cock assembly, complex structure, bulky, inconvenience is installed, dependability is poor, leaks sometimes.

The purpose of this utility model provides a kind of solar water heater automatic water controller, the convenience when adding water with raising.

The utility model is achieved in that flexible in the enclosure offset plate, and pull bar and lever fixing on the elastic weld wood are hinged, the lever other end is hinged on the bolster, the lever end has sealing block, and there is the inlet opening of water inlet pipe the sealing block below, also has outlet pipe on the shell.

But adopt solar water heater automatic water supplement when water tank lacks water of said structure, water tank can stop into water when full automatically, has saved user's time and efforts, the possibility of having got rid of the bad water tank that rises, simple in structure, it is little to take up room, and also can be used for the field that other need automatic water-supply.

Below in conjunction with description of drawings concrete structure of the present utility model and operation principle.

Fig. 1 is the schematic diagram of the utility model structure.Fig. 2 is its schematic diagram of installing and using situation.

As shown in Figure 1, on the automatic water controller of the solar water heater of the utility model, flexible offset plate (2) in the shell (3), there is fixed head (4) at the elastic weld wood middle part, be fixed with pull bar (6) on the fixed head, one end of pull bar and lever (11) is hinged, the other end of lever is hinged on the bolster (7), bolster is installed on the shell, the lever end is equipped with sealing block (8), inlet opening (9) on the water inlet pipe (10) is positioned at the sealing block below, also has outlet pipe (1) on shell, and spring (5) is between shell and fixed head.

As shown in Figure 2, outlet pipe (1) is installed in the water tank (13), also has blast pipe (12) at water tank upper.

During lack of water, spring (5) promotes elastic weld wood (2) and moves down in adding the water receptacle water tank, and pull bar (6) drives lever (11), makes on the sealing block (8) and moves, and breaks away from inlet opening (9), and water promptly enters in the outer shell cavity from the inlet opening, and then enters water tank through outlet pipe (1).When water tank was expired, the pressure of water produced pressure to elastic weld wood in the shell, made spring (5) compression, and pull bar drives lever, and sealing block (8) is moved down, and inlet opening (9) are blocked, and added the water process and stopped thereby making.

Since the area bigger (as 1600: 1) of elastic weld wood and inlet opening, the arm of force of lever bigger than also (as 6: 1), therefore, the pressure at intake-outlet two ends bigger (as 9600: 1).Usually the water inlet pipe tap water hydraulic is 0.4MPa, and then less water-head is arranged is the water that has less water level in the blast pipe in the water side, only makes elastic weld wood produce less pressure (as 4.16 * 10 ^-5MPa), can keep passing in and out the pressure balance of water end (W.E.), sealing block is blocked the inlet opening, water can not enter through the inlet opening again.

Sealing block (8) can be made by rubber.

Claims

The automatic water controller of solar water heater, it is characterized in that, flexible offset plate (2) in the shell (3), there is fixed head (4) at the elastic weld wood middle part, be fixed with pull bar (6) on the fixed head, one end of pull bar and lever (11) is hinged, the other end of lever is hinged on the bolster (7), bolster is installed on the shell, the lever end is equipped with sealing block (8), inlet opening (9) on the water inlet pipe (10) is positioned at the sealing block below, also has outlet pipe (1) on shell, and spring (5) is between shell and fixed head.
