Description

Automatic and manual integrated emptying device for water supply and drainage pipes of water heater

Technical Field

The utility model relates to a solar water heater and an outdoor heat preservation water tank, in particular to an automatic and manual integrated draining device for a water heater water supply pipe and a water drain pipe.

Background

At present, the upper and lower water pipes of the existing solar water heater and outdoor heat preservation water tank are basically connected with the upper and lower water pipes by adopting a water outlet at the lower part. The pipe always has water, and when hot water is used, cold water in the pipe must be discharged before hot water can be used. In winter, water in the water pipe is easy to freeze and cannot be used. The emptying anti-freezing valve is installed, the joint cannot be emptied, the reinforced heat preservation or the additional heat tracing belt is needed, and faults and potential safety hazards exist. The siphon principle is utilized to empty and prevent freezing of the pipeline, and the operation is complex and inconvenient when in use. ZL201020062409.3 discloses that the indoor pressure-bearing heat-preserving container is additionally arranged for emptying and freezing prevention, but the siphon water suction method is adopted, a small amount of water is used for many times, and a small amount of water in the container can be generated, so that hot water cannot be led out. The water tank is connected with the lower water outlet for use, and due to unbalance of the water levels of the outdoor heat preservation water tank and the indoor heat preservation container, accumulated water can be generated by multiple times of water use, so that the container is full of water, and normal emptying and freezing prevention are not realized.

In one embodiment of the present utility model, the return water receiving tank 24 is provided with a drain hole.

In one embodiment of the utility model, the side port of the three-way motor valve I2, the top of the upper sensor port 6, the side port of the three-way motor valve II 14 and the top of the two-way motor valve 17 are respectively connected with the controller instrument 3, and the controller instrument 3 is connected with a pipeline leading to the backwater storage tank 24.

In one embodiment of the utility model, the bottom of the water tank is provided with a drain switch 13.

When the utility model is actually used and implemented, after the installation, the tap water switch 1 is opened, the water supply start key is opened on the controller meter 3, the low-pressure hand is opened from the upper opening and the lower opening of the three-way motor valve I2, water starts to be supplied upwards along the water supply pipe 25, the water in the water tank is fully filled by the sensor, the low-pressure hand is closed from the lower opening of the three-way motor valve I2, the low-pressure hand is automatically opened from the side opening of the three-way motor valve I2, and because the water supply process is designed to supply water to the water tank water inlet 5 at the upper side of the water tank, water in the water pipe naturally flows out from the side opening of the low-pressure hand from the three-way motor valve I2 and flows into the backwater storage tank 24, so that the natural effects of full water self-stop and closed emptying are achieved. When water is used, the hot water faucet 22 or the water mixing valve 23 is opened, and the hot water naturally flows out; after the hot water tap 22 and the water mixing valve 23 are closed, as the water reservoir is an empty body (cavity), water flows into the water reservoir to naturally generate pressure, air naturally floats to the top of the lower water outlet 12 of the outdoor heat preservation water tank, and the water level of the upper water tank and the water level of the indoor water reservoir are kept at the same time, so that the water in the water reservoir is naturally in a water-free state, and the required emptying purpose is achieved. Because water is used for many times, the water level of the water storage device can slowly rise, when the water level rises to the set water level, the water level control switch 16 is turned on, the upper opening of the three-way motor valve II 14 above the water storage device is closed, the side opening of the three-way motor valve II 14 is automatically opened for air intake, the low-pressure two-way motor valve 17 below the three-way motor valve II is also automatically opened, and water of the water storage device can flow into the backwater storage pool 24.

Thus, the effect of opening to discharge hot water and closing to drain is achieved. When the water supply and drain pipes are not used, the water supply and drain pipes are in a water-free state at any time, the water supply and drain pipes are not frozen and blocked in winter, the water supply and drain pipes are well used in winter, and hot water is used at any time.

In summary, by means of the technical scheme, the three-way motor valve I is arranged on the water supply pipe, the three-way motor valve II is arranged on the water drain pipe, the water level control switch and the two-way motor valve are arranged on the water storage device, the three-way motor valve I, the upper sensor port, the three-way motor valve II, the water level control switch and the two-way motor valve are uniformly and coordinately controlled through the controller instrument, one side port of the three-way motor valve and one side port of the two-way motor valve are communicated with the backwater storage tank through pipelines to be used for draining the water, the utility model can be manually controlled, and the controller instrument and the motor valves can also be used for automatically controlling the parts such as the controller instrument and the motor valves to drain the water in the water outlet pipe, so that the water in the water outlet pipe can be emptied and antifreezed, the utility model can adapt to the requirements of different users, and the situation that the water pipe cannot be used by residual water in winter and the water in the outdoor heat preservation water tank can be avoided. The product can also be provided with a water level control switch and the like, and when the water level of the water tank is excessive, the excessive water is discharged, so that the water tank is protected.
