Description

Energy saving lever solenoid valve solar water saving device

technical field

The utility model relates to a water-saving device for a solar water heater, in particular to a water-saving device for timely emptying the water stored in the hot water pipe of the solar water heater.

Background technique

At present, most of the solar water heaters are installed on the roof, but in the current cities, most of them are high-rise buildings, and the distance between the hot water pipes from the roof to the user's room is relatively long, resulting in the hot water trapped in the hot water pipes after use. It gets cold again after not being used for a long time, and a large amount of hot water will be released when it is used next time, resulting in a waste of water resources. And existing solar water-saving device, almost all is installed water tank type water-saving device at the water outlet of bathing, not only complicated design, and expensive, is unfavorable for installation. In addition, the existing water-saving devices for the water outlets of solar hot water tanks are electronic valve-controlled water-saving systems, which consume a lot of power, and most of them are high-power solenoid valves, which are dangerous to operate. When the weather is irradiated, the user just cannot utilize the hot water that still has residual temperature in the solar hot water tank to take a bath.

Contents of the invention

In order to overcome the shortcomings of the above-mentioned solar water heater, the purpose of this utility model is to provide an energy-saving lever solenoid valve solar water-saving device, which has a simple structure, easy installation, low power consumption, safe use, and is suitable for water-saving of high-rise buildings.

To achieve the above purpose, the technical solution adopted by the utility model is: install a solenoid valve with a linkage lever between the outlet pipe and the hot water pipe of the solar hot water tank, the lever is hinged with the iron core rod and the valve stem at the same time, There is a valve ball closing the water inlet and the air vent, and the two valve balls of the water inlet and the air vent are alternate opening and closing stations, and the contact switch of the solenoid valve is arranged in the user's room.

The technical scheme of the utility model also includes:

There is an insulated hot water tank connected to the hot water pipe in the user's room. The outlet pipe of the insulated hot water tank and the cold water pipe are connected to the mixed warm water pipe through a three-way pipe joint. A water level gauge is installed on the insulated hot water tank. There is also an electric heater.

The iron core rod of the electromagnetic valve is equipped with a buckle with a return spring (its structure is the same as that of the spring telescopic ballpoint pen buckle).

The beneficial effects of the utility model are: the electromagnetic valve has a simple structure, is easy to install, consumes less power, and a small amount of power is enough to drive the iron core rod, so that the remaining water in the hot water pipe can be emptied while closing the water outlet of the solar hot water tank. So as to achieve the purpose of water saving; the solenoid valve is driven by batteries, so it is easy to install and safe to operate.

Description of drawings

Fig. 1 is the structural representation of the utility model.

In the figure: solar hot water tank 1, solenoid valve 2, hot water pipe 3, return spring 4, water level scale 5, heat preservation hot water tank 6, cold water pipe 7, contact switch 8, hot water valve 9, cold water valve 10 , Outlet pipe 11, buckle 12, iron core rod 13, lever 14, vent valve ball 15, valve stem 16, water inlet valve ball 17.

Detailed ways

As shown in Figure 1, the lever solenoid valve 2 of this water-saving device is installed in the position where the outlet pipe 11 of the solar water heating tank 1 is connected with the hot water pipe 3, and the contact switch 8 for controlling the action is connected to the bathroom through a wire. The linkage lever 14 of the electromagnetic valve 2 is hinged with the iron core rod 13 and the valve rod 16 at the same time, and one end of the valve rod 16 is connected to the valve ball 17 of the water inlet and the other end of the valve ball 15 of the vent port, and the two valve balls are in the working state of alternate opening and closing. bit. The hot water pipe 3 is connected to the indoor thermal water heater 6 after passing through the electromagnetic valve 2. The thermal thermal water heater 6 is provided with a transparent water level gauge 5 outside the thermal thermal water heater 6. The thermal thermal water heater 6 is also provided with an electric heater (not shown in the figure). The water outlet of 6 links to each other hot water valve 9, and cold water pipe 7 is provided with cold water valve 10, and hot water valve 9 and cold water valve 10 are connected to the mixed temperature water pipe of bathing by three-way pipe joint.

When using hot water, press the contact switch 8, the solenoid valve 2 is connected instantaneously, the iron core rod 13 is sucked, the corresponding action of the lever 14 drives the valve rod 16 to move, the vent valve ball 15 closes the vent port, and the water inlet valve ball 17 then opens the outlet pipe 11 and leads to the water inlet of the hot water pipe 3, and simultaneously the buckle 12 installed on the iron core rod 13 keeps the location of the iron core rod (the structure of the buckle 12 is similar to that of a spring telescopic ballpoint pen). buckle); when the user is about to finish bathing, the water level gauge 5 can be used to estimate the water consumption required, and the contact switch 8 is pressed again, the solenoid valve 2 is connected instantaneously again, and the iron core rod 13 is separated from the buckle 12 Reset by back-moving spring 4, water inlet valve ball 17 blocks the water inlet, and vent valve ball 15 opens vent to ensure hot water pipe 3 internal and external atmospheric pressure balance, and the water retained in the pipe is sent into heat preservation hot water tank 6 for the user to use up. When running into overcast and rainy weather or the weather with little sunshine, can directly put the water of solar hot water tank 1 surviving residual temperature into heat preservation hot water tank 6, can use after slightly heating by electric heater.
