[Chemical Knowledge]：Introduction to the role and use of the backwater valve

Read： 1353 Time：18months ago Source：Transform the World with Simplicity

As people pay more attention to energy conservation and environmental protection, more and more buildings and industrial equipment begin to use backwater valves to control the balance of water flow. The return valve is mainly used to control the return water temperature of the hot water system to prevent the water flow from wasting energy or affecting the normal operation of the equipment.

then what are the specific role of the return valve?

1. balance water flow

return valve the main role is to balance the water flow of the hot water system, to prevent the pipeline water level imbalance caused by equipment damage and waste of energy. The return valve can restore the balance of water flow by controlling the water flow speed in the return pipe, so as to achieve the purpose of energy saving.

2. energy saving

return valve another important role is to save energy. The backwater valve can monitor the water flow status in the pipeline at any time, control the water flow speed in real time, and prevent unnecessary energy waste. For example, in the heating equipment, the return water temperature is controlled by the return valve, so that the waste of heat energy due to the excessive water flow speed can be avoided, so that the heating equipment can work more efficiently.

3. Extend the life of the equipment

return valve can also prevent damage to the equipment caused by overheating or overcooling water flow. By reasonably controlling the water flow speed and water temperature in the return water pipeline, excessive wear and corrosion of pipelines and equipment can be effectively avoided.

In addition to the above functions, the return valve can also optimize the working efficiency of the equipment according to the specific usage scenario. For example, in some high-rise buildings, due to the difference in water pressure between each floor, it is easy to cause the heating equipment to work inefficiently. By setting the return valve, the water pressure between different floors can be balanced and the working efficiency of the whole system can be improved.

usage scenarios:

return valves are used in many industries, mainly involving the flow of media that need to be heated or cooled, including heating equipment, air conditioning equipment, industrial cooling equipment, etc. Specifically, the return valve is suitable for the following scenarios:

1. heating system

in the heating system, by setting the return valve can control the return water pipe in the hot water flow rate, to achieve more efficient thermal energy utilization effect.

2. Air conditioning system

In the air conditioning system, the water pressure difference between different floors in the cooling system can be balanced by setting the return valve, thereby ensuring the operating efficiency of the entire system.

3. Industrial cooling system

In the industrial cooling system, the cooling water flow speed and water temperature can be controlled through the return valve to prevent the normal operation of the equipment from being affected by the rapid water flow. How do

choose a backwater valve?

When choosing a backwater valve, you usually need to consider the following factors:
