What does the solar tee with anti-backflow function mean?

Introduction What does the solar tee with anti-return water function mean? When the solar water heater is installed at home, there is such a tee on the water supply pipe and the cold water part should be stopped.

What does the solar tee with anti-backflow function mean?

This means that when a solar water heater is installed in a house, there is such a tee on the water supply pipe and a check valve is required for the cold water part. Therefore, there is such a product on the market, which is a three-way with a check valve at one end. This is a combination product of a three-way valve and a check valve.

How to install the inlet and outlet pipes of solar water heaters

It can be determined that the problem is not the solar energy itself, but the pressure water if municipal water pressure. is lower than the solar pressure, the solar water will flow back into the water pipe. The solution is: install a check valve before or behind the solenoid valve on the water supply side. The necessary accessories are also very simple, a roll of raw material tape, an outer wire and a check valve. there are noneus. A piece of raw material tape, a piece of outer wire and two or three pieces of check valve. It's the cost.

1. Installation of the pipeline

To prevent the backflow of hot water, a non-return valve must be installed in the pipeline. The check valve is installed where the hot water pipe is connected to the tap water and is installed in a vertical direction to ensure that the arrow is upwards, in the same direction as the tap water. Block the exhaust vent. All pipes must be effectively secured. Choose a suitable size hose clamp, and the distance between hose clamps should not exceed 1 meter. The ball valve should be installed at the junction of the solar hot water system pipe and tap water.

2. Pipe insulation

It is recommended to use polyurethane, rubber or poly materialshigh quality ethylene (wall thickness 20-50mm) as insulation materials, easy to install and dismantle. and do not require water absorption, low thermal conductivity and good dimensional stability. After testing the pipes with water, the heating cables are installed and then insulated.

3. Antifreeze of pipes

In areas with low temperatures and easy freezing, closed balcony pipes should be added to increase the antifreeze properties of the heating cables. This heating cable has the characteristics of anti-aging, self-limiting temperature, fast start-up speed, low operating cost, easy installation and maintenance and 'strong thermal stability.

Detailed information

Daily maintenance of solar water heaters:

1 When installing a water heater solar, there may be dust. or dustns the water line If there is an oily smell, you can open the faucet to remove debris before using it for the first time.

2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.

3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.

4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
