Brief analysis, static balance valve and dynamic balance valve

by:Sure     2021-08-22
The dynamic balance valve is divided into two types: flow (flow dynamic control valve) and differential pressure control, which can be selected according to actual needs. The dynamic balance valve is used to solve the branch pressure balance problem caused by the frequent action of the temperature control valve at the end of each station. The difference between it and static is: static balance valve needs to be locked after one-time debugging through a special intelligent instrument to control the total water volume of the system within a reasonable range. The dynamic balance valve is divided into flow rate (flow dynamic control valve) and differential pressure control. Selection for actual needs. The dynamic balance valve is used to solve the branch pressure balance problem caused by the frequent action of the temperature control valve at the end of each station. The difference between it and the static state is that the static balance valve needs to be locked after a one-time debugging by a special intelligent instrument to control the total water volume of the system within a reasonable range, but each time the change is made, the valve needs to be re-locked by the instrument, and the dynamic is independent It doesn’t have to be so troublesome. It relies on the pressure change of the adjusted medium in the pipe network for automatic constant flow. The static one is slightly cheaper in terms of engineering cost. The working principle of the dynamic balance valve: by changing the flow area of u200bu200bthe spool of the balance valve to adapt to the changes before and after the valve, so as to achieve the purpose of controlling the flow. The dynamic balance valve can be installed on the water supply pipe or on the return pipe. When the working pressure of the system fluid exceeds the allowable working pressure of the radiator, for safety reasons, the dynamic balance valve should be installed on the water supply pipe. Static balance valve is also called balance valve, manual balance valve, digital lock balance valve, two-position control valve, etc., used to solve the problem of branch pressure balance in pipeline design. The working principle of the static balance valve is: by changing the gap (opening) between the valve core and the valve seat, the flow resistance flowing through the valve is changed to achieve the purpose of adjusting the flow. The object is the resistance of the system, which can reduce the new water volume. According to the proportional distribution calculated by the design, each branch will increase and decrease proportionally at the same time, which still meets the flow demand of part of the load under the current climate demand, and plays a role of heat balance. The static balance valve can be installed on the water supply pipe or on the return pipe. Generally, it should be 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 water supply (return) pipe does not need to be equipped with a shut-off valve. Regardless of the static balance valve or the dynamic balance valve, it is an impedance element by itself, especially the dynamic balance valve, which requires the system to consider the additional head caused by the balance valve when selecting the water pump.
