Which switch is Bora heating?

Pacific Auto Network has a temperature knob on the air conditioning panel, which is divided into two sides: red stands for high temperature and blue stands for refrigeration. Hit the car first and let the engine warm up. After a few minutes, turn the knob to the red side, and the hot air will come out of the tuyere. If the tuyere temperature is not hot, it may be that the heater water tank is blocked and needs cleaning. If the blockage is too serious, it needs to be replaced.

Home heating will install two pipes, a water inlet pipe and a return pipe, and each pipe has a valve to control the temperature. If the heater is not used for a long time, it may be necessary to open the valve to exhaust, and the valve can be closed when the water drops. There will always be a sign on the valve that says the opening and closing direction, but sometimes the words will be worn off or dirty, so how to open and close?

Schematic diagram of heating valve switch at home There will be a water inlet valve and a water return valve on the radiator, which are generally closed clockwise and opened counterclockwise. There are two temperature control valves, the upper one is a switch, and the lower one is to adjust the water temperature. You can see if there is a letter "s" on the heating valve, which means "off"; If there is an "O", it means "On"; Some will have an arrow pointing near the letter, and twisting in the direction of the sign will open or close the valve.

Where is the heating valve at home? The valve is on the main pipeline, and the supply return pipe is horizontal, open horizontally and close vertically. The supply pipe and the return pipe have a valve. The return valve of heating is on the return pipe, and the inlet valve is on the inlet pipe. The heating pipe with filter is a water inlet pipe with high temperature; The heating pipe without filter is return pipe, with low temperature. The valve on the return pipe is a backwater valve, which will be used when exhausting. Timely exhaust can accelerate water circulation and improve heating effect.

There are two types of return valves. One is the ball valve, which is controlled by the handle. The handle is opened in the same direction as the pipeline, and the handle and the pipeline are closed at 90 degrees; The other is the gate valve, which is controlled by rotating the handwheel. Open counterclockwise and close clockwise.

1. Adjust the valve to a proper position.

2. Open the heater return valve to discharge the air in the heater. At this point, the heater began to heat up. When the heating is very hot, stop exhausting. At this point, the debugging has been completed, so once the heating valve is successfully debugged, it cannot be opened and closed at will.

3. If there is something wrong with the valve, please stop working and find someone in time.

4. During the hot water test, please leave someone at home, open the inlet valve and the return valve, turn off the running air, and do not shake the heating pipe or increase the weight.
