The winter in the north is very cold. At this time, heating is particularly important. The heating may not be familiar to most people, but how much do you know about the heating valve ? What should you watch out for when using it? How to wash you know? Next, Xiaobian asks everyone to answer one by one.
[Introduction to heating valve]
The heating valve just refers to a kind of fitting of the radiator system and is a kind of valve. Currently, the commonly used valves of the heater system on the market are mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, pressure-regulating valve, and minus. Pressure valve, electro-dynamic valve, etc.
[Use of Heating Relief Valve Precautions]
A. The valve on the heating pipe is not free to switch. If the heating system is run for the first time, it usually needs to be debugged.
Specific operation method
1 Adjust the position. Adjust each riser valve to the proper position;
2 Open the manual bleed valve of each radiator to discharge the air accumulated in the radiator, or open the exhaust valve installed on the top of the system and exhaust the exhaust valve until each radiator is heated up. The commissioning is completed. Once the commissioning is completed, the valve should be fixed and cannot be switched on and off.
3. When turning on the valve, turn the handwheel clockwise. When closing, turn the handwheel counterclockwise. Press the open/close indicator to rotate it in place. Radiator can not be arbitrarily changed position, can not freely discharge water from the system, lose hot water, the water temperature in the pipe network will quickly reduce, resulting in lower indoor temperature.
4. If it is found that the valve is faulty, stop using it immediately to find out the cause and clear the fault.
[heating valve cleaning step]
Parts must be processed through the following processes before assembly:
1, according to processing requirements, some parts need to be polished, the surface can not be processed burr;
2, all parts degreasing treatment;
3, after the completion of degreasing pickling passivation, cleaning agent does not contain phosphorus;
4. After pickling, purifying and rinsing with purified water, no chemical residues can be left. Carbon steel components eliminate this step,
5. One by one component is wiped with a non-woven fabric, and the surface of the components such as wire wool cannot be retained, or it can be blown dry with clean nitrogen;
6. Wipe the individual parts with non-woven cloth or precision filter paper and wipe the pure alcohol until no dirt is found.
The above introduced the precautions of the heating pressure reducing valve and how to clean the steps. I hope to be helpful to everyone.
