The balance valve is a valve that performs dynamic and static balance adjustment under hydraulic conditions. Such as: static balance valve, dynamic balance valve.
Static balance valve is also known as balance valve, manual balance valve, digital lock balance valve, two-position control valve, etc. It changes the flow resistance through the valve by changing the gap (opening) between the valve core and the valve seat to achieve adjustment. The purpose of the flow is the resistance of the system, which can balance the distribution of the new water according to the proportion calculated by the design, and increase or decrease each branch at the same time in proportion to still meet the flow demand of the partial load under the current climate demand. The role of heat balance.
Dynamic balance valve is divided into dynamic flow balance valve, dynamic differential pressure balance valve, self-operated self-pressure differential control valve, etc.
Dynamic flow balance valve is also known as: self-operated flow control valve, self-operated balance valve, constant flow valve, automatic balance valve, etc. It automatically changes the resistance coefficient according to the system operating conditions (pressure difference). Within the range, the flow through can be effectively controlled to maintain a constant value, that is, when the pressure difference before and after the valve increases, the automatic closing action of the valve can keep the flow from increasing. On the contrary, when the pressure difference decreases, the valve When the pressure difference is smaller or larger than the normal working range of the valve, it cannot provide additional pressure head after all. At this time, when the valve is fully opened or fully closed, the flow rate is still higher than the set value. Low or high flow cannot be controlled.
