Control of water flow rate balance analysis balance valve applicable scenarios
Balance valves are valves used to maintain a closed pressure balance in the pipe. It is generally installed in a hot water system, the function of which is to restrict the water pressure generated by the water in front of the valve to ensure that the water pressure of each branch pipeline is almost the same. It works through the combination of the balance valve, butterfly valve and drain valve, using an annular space between the components.
Balance valves are mainly used in hot water systems, such as domestic water supply and industrial boiler systems, and they can also be used in other systems such as cold water and steam. They are widely used due to their simple structure and convenient installation. The function of balance valve is mainly to achieve a balanced system pressure, in order to prevent the reverse pressure of the hydraulics caused by excessive differential pressure on the two sides of the valve, or to cause water hammer shock and unsafe operation.
The balance valve is an important part of the water distribution network and can be found in some high-rise buildings, domestic water supply systems and other places. During its normal operation, the valve can ensure that the pressure of the user pipe network is balanced and not affected by the pipe network pressure, thus avoiding unnecessary losses.
The balance valves are mainly composed of the valve core, valve body, valve seat, and spring. The valve core has a large hole and small hole. During operation, the pressure difference between the inlet and outlet of the valve is balanced and the compensating fluid flux is controlled by adjusting the position and stroke of the valve core. The coil spring is used to push the valve core to ensure that the balance valve can resist more pressure difference and open and close more smooth.
The balance valve can be used in the water supply and drainage systems of residential, high-rise buildings, hospitals and other places, so that the water in the respective pipes can be balanced in a short time and integrated to the corresponding section. During the operation, the valve can balance the influent and effluent flow rate in order to ensure the efficient operation of the system.
In addition, the balance valves can also be used in areas with harsh operating conditions such as high pressure, high temperature and high frequency. They can meet the needs of differential pressure in the system, reduce water hammer and water column noise, and ensure the safe and reliable operation of the system.
In summary, the balance valve is an important device for a balancing system, which can guarantee the distribution of pressure, reduce the differential pressure loss and make the system work stably, which is especially suitable for the water heating system. When choosing and installing a balance valve, it is necessary to select the appropriate valve based on the operating conditions of the system and consider the effect of the valve efficiency on the system.
