Balance valve principle balance valve structure balance valve feature balance valve application balance valve construction

The balancing valve is a special function valve with good flow characteristics, valve opening indication, opening locking device and pressure measuring small valve for flow measurement. Using a special intelligent meter, input the valve type and opening value, and directly display the flow value flowing through the balancing valve according to the measured differential pressure signal. As long as the balance valve of the appropriate specification is installed in each branch and user inlet, And with a dedicated smart meter for one-time debugging, the traffic of each user can reach the set value.

The balance valve is a valve that adjusts dynamic and static balance under hydraulic conditions. Static balance valve, also known as balance valve, manual balance valve, digital lock balance valve, double position control valve, etc., it changes the flow resistance through the valve to change the gap between the valve core and the valve seat (opening) The purpose of the flow, the object of which is the resistance of the system, can balance the new water quantity according to the proportion of the design calculation, and the branches will increase and decrease at the same time, still satisfying the flow demand of the partial load under the current climate demand. The role of heat balance. The dynamic balancing valve is divided into a dynamic flow balancing valve, a self-operating self-pressure differential control valve, and the like.

Dynamic flow balancing valves are also known as self-operated flow control valves, self-operated balancing valves, constant Flow Valves, and automatic balancing valves. The self-operated Flow Control Valve automatically changes the resistance coefficient according to the change of the operating conditions of the system. Within a certain pressure difference range, the flow rate can be effectively controlled to maintain a constant value, that is, when the differential pressure before and after the valve increases, The automatic closing action of the valve can keep the flow rate from increasing. Conversely, when the pressure difference is reduced, the valve automatically opens and the flow rate remains constant, but when the pressure difference is less than or greater than the normal working range of the valve, it is after all Additional heads are not available, and the flow is still lower or higher than the set flow rate when the valve is fully open or fully closed.

Dynamic differential pressure balancing valve, also known as self-operated differential Pressure Control Valve, differential pressure controller, voltage variable synchronizer, differential pressure balance valve, etc., it uses differential pressure to adjust the opening of the valve, using the pressure of the spool The change is made to compensate for the change of the pipeline resistance, so that the pressure difference can be kept basically unchanged when the working condition changes. The principle is that the pressure difference of the controlled system can be effectively controlled within a certain flow range, that is, when When the pressure difference of the system increases, it can ensure the pressure difference of the controlled system increases by the automatic closing action of the valve. Otherwise, when the pressure difference is reduced, the valve automatically opens and the pressure difference remains constant. Self-operated differential pressure control valve, the automatic valve plug is closed in the control range, the pressure difference between the two ends of the valve exceeds the preset value, the valve plug automatically opens and automatically adjusts the opening under the action of the pressure sensitive membrane to maintain the pressure at both ends of the valve The difference is relatively constant.
