Description

Non-pressurized fully automatic solar water heater tank

technical field

The utility model relates to a non-pressurized full-automatic solar water heater water tank, which belongs to the technical field of solar water heaters.

Background technique

Existing non-pressurized full-automatic solar water heater water tank mainly adopts common single tank, and an external floating ball tank is attached. Due to the large mixed layer of cold and hot water, low temperature water flows out prematurely, and the utilization rate of hot water is low, especially in low temperature seasons.

Contents of the invention

The purpose of this utility model is to provide a non-pressurized automatic solar water heater water tank, which can overcome the above-mentioned shortcomings, and has the advantages of beautiful appearance, easy installation, fast heating, and large water output.

There is an insulation layer between the outer shell and the inner tank of the water tank. A floating ball box is installed in the water tank, which is connected with the inner tank through the water nozzle. A baffle is set in the inner tank. And the electric heater, there is a floating ball in the floating ball box connected with the valve body by a pull rod, and the floating ball is connected with the water inlet pipe.

Description of drawings

Figure 1. Schematic diagram of a non-pressurized fully automatic solar water heater tank

Between the shell (12) and the inner tank (7) of the water tank is an insulating layer (13), and the middle part of the inner tank (7) is equipped with a baffle plate (8), and the baffle plate (8) has a through hole (16). Exhaust faucets (9) and drain nozzles (10) are arranged, electric heaters (11) are arranged below the drain nozzles (10), and the drain nozzles are connected to a valve (15) by pipelines (17); There is a floating ball box (4) at the bottom, and a floating ball (3) is connected with the floating ball valve body (2) by a pull rod (14) in the box; the valve body (2) is connected with the water inlet pipe (1), and the floating ball box (4) communicate with the inner tank (7) by faucets (5), (6).

The advantages of this water tank are: a floating ball box and a baffle are arranged in the tank, which can control the water level of the water inlet;

Detailed ways

When the water tank is initially filled with water, tap water enters the float tank (4) from the water inlet pipe (1) through the float valve body (2), and then enters the inner tank (7) from the water inlet (6). , the water is constantly increasing in the right chamber of the baffle (8), when the water level reaches the position of the through hole (16) of the baffle (8), the water enters the left chamber of the baffle (8) through the through hole (16) ; Along with the overall rise of the water level in the inner tank (7), the water level in the float box (4) also rises, and the float (3) rises to the closed position with the water level, and the pull rod (14) is pulled to close the float valve body (2) , the tap water stopped replenishing water.

When using water, open the hot water valve (15), hot water flows out from the drain nozzle (10), the water level in the inner tank (7) drops, and forms a water level difference with the water level of the float tank (4), and the water in the float tank (4) Enter the right side chamber of the inner tank (7) through the water inlet (6) to replenish water, and at the same time the floating ball (3) drops with the water level, the pulling force of the tie rod (14) decreases, and the water pressure torque of the tap water overcomes the pulling moment of the floating ball valve pull rod (14) Enter the float box (4) to replenish water, and the float box (4) water level rises, so the water in the float box (4) just continues to enter the inner bag (7) right side chamber to replenish water. The cold water entering the right side chamber of the inner tank (7) presses the hot water in the right side chamber into the left side chamber of the baffle (8) from the bottom. Since the baffle (8) is attached with a layer of heat insulating material, the cold water is mainly connected to the right side. Indoor hot water undergoes heat exchange, and a very small amount of heat conduction occurs between the inner tank (7) and the left chamber, and because the cold water is at the bottom, the mixed layer of cold and hot water is reduced, and the utilization rate of hot water is greatly improved.

An electric heater (11) is arranged at the end of the water outlet (10). Because the baffle (8) divides the inner tank (7) into left and right side chambers, the electric heater only heats the water in the left chamber so that the water temperature rises quickly. It saves electricity and provides convenience for users to use water.
