Dynamic balance valve is divided into flow (flow dynamic control valve) and pressure (self-pressure control valve) control of two, according to the actual needs of choice. Dynamic balance valve is used to solve the balance of branch pressure balance caused by the frequent action of temperature control valves at the end of each station. The static difference is that: static balance valve (also known as digital lock balancing valve) need to go through a dedicated intelligent instrument after a one-time debugging lock, the system's total water control within a reasonable range, but each change requires the instrument through the valve To re-lock, the dynamic is self-need not so troublesome, rely on the pipe network to adjust the pressure of media itself for constant flow, static in the project cost to be slightly cheaper. Dynamic balancing valve works: By changing the balance valve spool flow area to adapt to the valve before and after the change, so as to achieve the purpose of controlling the flow. Dynamic balance valve can be installed in the water supply pipe can also be installed in the return pipe. When the system fluid working pressure exceeds the allowable working pressure radiator, for safety reasons, the dynamic balance valve should be installed in the water supply pipe. Static balance valve, also known as balancing valve, manual balancing valve, digital lock balance valve, two-position control valve, used to solve the pipeline design branch pressure balance problem. Static balancing valve works by changing the valve core and seat gap (opening), to change the flow resistance through the valve in order to achieve the purpose of regulating the flow of its object is the system resistance, to the new amount of water In accordance with the design of the proportion of balanced distribution, each branch at the same time increase or decrease at the same time, still meet the needs of the current part of the climate load demand, play a role in thermal equilibrium. Static balance valve can be installed in the water supply pipe can also be installed in the return pipe, generally to be installed in the return pipe, especially for high temperature loop, for ease of debugging, but also installed in the return pipe, the installation of the balance valve No need to set stop valve for return pipe. Both static balance valve or dynamic balance valve, itself is the impedance element, especially the dynamic balance valve, requiring the system when the optional pump must consider the balance valve caused by the additional head.
