BALANCING VALVE WORKING PRINCIPLE
Balancing valve working principle is about how balance valve works. Balance valve is a dynamic and static balancing valve under hydraulic conditions, such as static balance valve, dynamic balance valve.
Valve body material: cast iron, cast steel .work pressure is 0.6-4.0MPA.
The working temperature is -5c-350C.
Valve caliber DN15-DN300.
Connection mode: flange, internal thread, driving mode: manual and electric.
Manufacturing standard: national standard.
1. What is automatic balancing valve working principle?
Balance Valve Working and Intelligent Instrument
Balancing valve function is realized through intelligent instrument and the valve has good flow characteristics. What’s more, balancing valve has a valve opening index, opening locking device, and pressure measuring valve for flow measurement. However, how do balancing valves work? Its functions are realized through intelligent instrument panel
By using the special intelligent instrument, the flow valve flowing through the balance valve be directly displayed by inputting the valve type and opening valve according to the measured pressure different signal. As long as the balance valve with appropriate specifications is installed in each branch and user’s entrance and debugged once with the special intelligent instrument, the flow rate of the user can reach the set valve.
2. Balancing Valves Types
MstnLand provides many types of balance valves such as static balance valve and dynamic balance valve.
Static Balancing Valve
Static balancing valves are also called balancing valves, manual balancing valves, digital locking balancing valves, double-position regulating valves, etc, balance valve working is through changing the clearance between the spool and the seat (opening ), to change the flow resistance through the valve in order to achieve the purpose of regulating flow, its object of the action is the resistance of the system, which can distribute the new water in proportion to the design calculation, increase and decrease the branches in proportion at the same time .still meet the flow demand of part of the load under the current climate needs, can play the role of heat balance. Dynamic balancing valves, self-operated balance valve, constant flow valve, automatic balance valve etc. MSTNLAND cast iron butterfly balance valve is a product in high demand in the market.
Automatic balancing valve working principle is to automatically changes the drag coefficient according to the change of system working condition (different pressure ) in a certain range of pressure difference, the flow-through can be effectively controlled to maintain a constant valve, that is, when the pressure difference before and after the valve increase, the flow through the valve can be maintained by the action of automatic closing small, on the contrary, when the pressure difference decrease, the valve opens automatically and the flow rate remains constant. however when the pressure difference is smaller or larger than the normal working range of the valve, it can not provide additional pressure head after all. In order to avoid unnecessary trouble, high performance valve is very necessary. At this time, the flow tare of the valve to be full open or closed position is still lower or higher than the set flow rate can not be controlled.
Dynamic Differential Pressure-Balancing Valve
Dynamic differential pressure-balancing valve, also known as self-operated differential pressure control valve, differential pressure controller, constant voltage variable synchronizer, differential pressure balancing variable, etc., balancing valve working principle is about using differential pressure to adjust the opening of the valve and uses the change of pressure drop of the valve core to compensate for the change of pipeline resistance, so as to keep the differential pressure basically unchanged, when thwart working condition changes, the valve working principle is that in a certain flow range, it can effectively control the constant pressure difference of the controlled system .that is, when the pressure difference of the system increase, it can ensure that the pressure difference of the controlled system, the valve opens automatically closing the valve, when the pressure difference decrease, the valve opens automatically, and the pressure difference remains constant. the self-operated pressure difference control valve has an automatic plug closing state within the control range, the pressure difference between the two ends of the valve exceeds the preset valve. the plug opens automatically and adjusts the opening automatically under the action of the pressure-sensitive film to keep the pressure difference between the two ends of the valve relatively constant .
