Description

Antifreeze pipe device for solar water heater

technical field

The utility model relates to an antifreeze pipe device, which is suitable for the field of solar water heaters.

Background technique

Since a part of the water delivery pipe of the solar water heater is always placed outdoors, in the cold winter, the water in the water delivery pipe will freeze, and the water delivery pipe will be blocked in the lightest case, and the solar water heater will no longer be used in winter, and the water delivery pipe will be frozen and cracked in severe cases. Using solar water heaters, and when the temperature rises, the leakage of the water pipes will cause water waste and pipe replacement problems. For this reason, some families empty the water in the solar water tanks and their pipes before the water pipes freeze in winter, or turn on the solar water heaters. The hot water tap dripped slowly. The utilization efficiency of solar water heaters is too low in winter, and some manufacturers also sell heating tapes for water pipes, wrap the heating tapes on the water pipes, and turn on the electricity to heat and dredge the water pipes when it freezes, which increases the economic cost.

And in order to make the solar water heater have antifreeze function, generally adopt in the prior art to connect an air pipe in parallel on the water pipeline, the lower end of the air pipe is introduced into the room and connected to a valve, and the upper end of the air pipe is connected to the upper end of the water pipe by a water stop valve. Although the one-time economic cost of this scheme is not high, it is mainly used for the initial installation of solar water heaters. The problem of restricting the exhaust, because the common household solar water heater is a non-pressurized water heater, and only one overflow port and exhaust port are left in the water tank. If there is foreign matter blocking the overflow port or the air circulation at the overflow port is not smooth, the water tank will The internal air cannot be replenished immediately, and the pressure difference between the inside and outside of the water tank will cause the water tank to collapse.

Gu, need provide a kind of new solar water heater antifreeze pipe device to solve the above-mentioned technical problems.

Utility model content

In order to solve the problems in the prior art, the utility model provides a solar water heater antifreeze pipe device with good antifreeze effect.

The antifreeze pipe device of the solar water heater of the present utility model comprises a thermal insulation water tank, the upper end of the thermal insulation water tank is provided with a sensor jack, the lower end is provided with a water delivery pipe, the upper end of the water delivery pipe is provided with a solenoid valve, and the lower end is provided with a hot water valve and a tap water valve , the lower end of the electromagnetic valve is connected with a tee, and the sensor jack is communicated with the tee through an air guide tube.

Preferably, the solenoid valve is a normally closed solenoid valve.

When using solar energy, close the valve of the hot water faucet and open the tap water valve. The tap water flows through the air guide pipe from the tee and is injected into the water tank from the sensor jack. After the water is full, close the tap water valve. When the water heater is not filling water, the hot water tap valve is in normal In the open state, let the cold water in the water pipe flow out naturally, so as to ensure that there is no water in the water pipe, so as to achieve the antifreeze effect.

The antifreeze pipe device of the solar water heater of the utility model plays a good antifreeze effect on the antifreeze of the solar water heater in winter by changing the device of the original pipeline, and greatly saves electric energy compared with the prior art.

Description of drawings

Fig. 1 is the schematic diagram of the antifreeze pipe device of the utility model solar water heater.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, thereby making a clearer definition of the protection scope of the utility model defined.

Referring to shown in Fig. 1, the antifreeze pipe device of the solar water heater of the present utility model comprises an insulated water tank, the upper end of the insulated water tank is provided with a sensor jack 1, the lower end is provided with a water delivery pipe 2, and the upper end of the water delivery pipe 2 is provided with a solenoid valve 3 , the lower end is provided with a hot water valve 4 and a tap water valve 5, and the lower end of the solenoid valve 3 is connected with a tee 6, and the sensor jack 1 is communicated with the tee 6 through an air duct 7.

Preferably, the solenoid valve 3 is a normally closed solenoid valve.

When using solar energy, close the hot water faucet valve 4, open the tap water valve 5, tap water flows through the air guide pipe 7 from the tee 6, and pours into the water tank from the sensor jack 1, and close the tap water valve 5 after the water is full, and the water heater is not in the water supply state , the hot water faucet valve 4 is in a normally open state, allowing the cold water in the water delivery pipe 2 to flow out naturally, thus ensuring that there is no accumulated water in the water delivery pipe 2, thereby achieving the antifreeze effect.

Connect indoor electromagnetic valve 3 power switch when putting hot water, electromagnetic valve 3 is opened, hot water flows out from the hot water faucet valve 4 that is in normally open state, closes power switch and gets final product after practical use, and needn't close hot water faucet.

Practice has proved that the antifreeze pipe device of the solar water heater of the utility model has played a very good antifreeze effect on the antifreeze of the solar water heater in winter by changing the device of the original pipeline. Compared with the prior art, it also greatly saves electric energy. .
