Analysis of Dynamic Balance Valves and Static Balance Valves

Analysis of dynamic balance valve and static balance valve: Dynamic balance valve is divided into flow (flow dynamic control valve) and differential pressure (self-pressure differential control valve) control, according to actual needs. The dynamic Balancing Valve is used to solve the balance problem of the branch pressure difference caused by the frequent operation of the temperature control valve at each end. The difference between it and static is: static balance


Guide: Dynamic balance valve is divided into flow (flow dynamic control valve) and differential pressure (self-operated Differential Pressure Control Valve) control, according to actual needs. The dynamic balancing valve is used to solve the balance problem of the branch pressure difference caused by the frequent operation of the temperature control valve at each end.



The difference between static and static is that the static balance valve (also called the digital lock balance valve) needs to be locked after one-time debugging by a special intelligent instrument, and the total water volume of the system is controlled within a reasonable range, but each time the change needs to pass the instrument to the valve Re-locking, the dynamic is self-reliant, not so troublesome, relying on the pressure change of the medium being adjusted in the pipe network to automatically constant flow, static in the construction cost is slightly cheaper.



The working principle of the dynamic balancing valve: to adapt to the change of the valve before and after the valve by changing the overflow area of the valve core of the balancing valve, thereby achieving the purpose of controlling the flow.



The dynamic balancing valve can be installed on the water supply pipe or on the return pipe. When the system fluid working pressure exceeds the allowable working pressure of the radiator, the safety balancing valve should be installed on the water supply pipe for safety reasons.



Static balance valve, also known as balance valve, manual balance valve, digital lock balance valve, double position control valve, etc., is used to solve the problem of branch pressure difference balance in pipeline design.



The working principle of the static balance valve is to change the flow resistance flowing through the valve to change the flow resistance by changing the gap (opening) between the valve core and the valve seat. The object of the static balance valve is to adjust the flow rate. According to the proportion of the design calculation, the branches are increased and decreased at the same time, which still meets the flow demand of part of the load under the current climate, and plays a role of heat balance.



The static balance valve can be installed on the water supply pipe or on the return pipe. It is usually installed on the return pipe, especially for the high temperature loop. For the convenience of debugging, it should be installed on the return pipe and the balance valve is installed. The supply (return) water pipe does not have to be equipped with a shut-off valve.



Regardless of the static balancing valve or the dynamic balancing valve, it is itself an impedance component, especially a dynamic balancing valve, which requires the system to consider the additional head caused by the balancing valve when selecting the pump.
