What is the main plumbing return pipe? Where is the balance valve installed in the main pipeline? Does every radiator need a balance valve?

There are two main types of water heating pipes. The pipe from the heat source to the radiator is the upper pipe, and the water temperature is high. When the heat energy is radiated by the radiator and then flows back to the heat source for recycling, the pipeline is called return pipe, and the water temperature is low. The backwater main pipe is the main pipe for multiple radiators to flow to the heat source.

The balance valve is used to balance the flow between radiators, which is generally installed at the joint between the main water pipe and the radiator branch pipe, and not every radiator has it.

It is suitable for the return water main pipe and branch pipe of heating system and air conditioning water system, which is a major update of the design of balance valve. Its characteristic is that one valve is multi-purpose, which can not only accurately adjust the resistance, but also play the role of opening and closing. As the main shaft of the valve body is sealed by the annular sealing ring,

Without maintenance, all functions such as measurement, adjustment, emptying and charging at night can be completed on site without interrupting the operation of the system and affecting the overall thermal insulation of the system.

Because the balance valve has the function of flow measurement, in order to stabilize the water flow before and after the valve and ensure the measurement accuracy, the balance valve should be installed in the straight pipe section as far as possible.

Extended data:

1, the construction of floor radiant heating system should avoid overlapping construction with other types of work, resulting in difficult coordination or unclear responsibilities, delayed construction period and difficult quality assurance. Users need to let us communicate with the decoration company in advance to coordinate the work coordination process;

2, hydropower transformation should be completed before the floor heating system construction approach. Before the installation of the floor heating system, it is necessary to ensure that the construction of water and electricity pipelines on the construction site is completed, and the kitchen and bathroom are tested and accepted. The ground in the construction area is flat and clean, and there are no exposed steel bars, water and electricity pipelines and any equipment, materials and sundries that affect the construction.

3. It's the same as looking for a decoration company to do bean stone concrete backfill. We suggest that the decoration company do this project, and the decoration company can also pay attention to it to minimize the possibility of damaging the floor heating during construction;

4. The owner shall assist us to coordinate the relationship with the property management company and the neighborhood, and create conditions for normal construction, including going to the property management and other relevant departments to handle the corresponding personnel and equipment passes, commencement and acceptance approval procedures, etc.
