Counterbalance valve is a special function of the valve, it has good flow characteristics, the valve opening instructions, opening locking device and for the flow measurement of small pressure valve. The use of special intelligent instruments, enter the valve model and the opening value, according to the measured pressure signal can be displayed directly through the balance valve flow value, as long as each branch and user access to install the appropriate specifications of the balance valve, And with a dedicated intelligent instrument one-time debugging, you can make the user's flow to set value. Balance valve is under hydraulic conditions, play a dynamic, static balance adjustment valve. Static balance valve, also known as balance valve, manual balancing valve, digital lock balance valve, two-position control valve, which is by changing the valve core and seat clearance (opening), to change the flow resistance through the valve to achieve regulation The purpose of traffic, the role of the object is the system resistance, the new amount of water can be balanced according to the proportion of design and distribution, each branch at the same time proportional increase or decrease, still meet the needs of the current part of the load demand climate needs, play The role of heat balance. Dynamic balance valve is divided into dynamic flow balance valve, self-pressure differential valve and so on. Dynamic flow balance valve also known as: self-flow control valve, self-balancing valve, constant flow valve, automatic balancing valve. Self-operated flow control valve is based on changes in system conditions automatically change the drag coefficient, within a certain pressure range, you can effectively control the flow through to maintain a constant value, that is, when the valve before and after the pressure increase, through The valve automatically closes the small action to keep the flow does not increase, on the contrary, when the pressure drop decreases, the valve automatically open big, the flow remains unchanged, but when the pressure difference is less than or greater than the normal working range of the valve, after all, it Can not provide additional pressure head, the valve hit the fully open or fully closed position flow is still lower than the set flow rate or high can not be controlled. Dynamic pressure balance valve, also known as self-pressure control valve, differential pressure controller, regulator variable synchronizer, differential pressure balance valve, which is used to adjust the pressure valve opening, the use of spool pressure Reduce the change to make up for the change of the pipeline resistance so as to keep the pressure difference basically unchanged when the working conditions change. Its principle is that within a certain flow range, the pressure drop of the controlled system can be effectively controlled, that is, when When the system pressure increases, the valve will automatically close the small movements, which can ensure that the controlled system pressure increases. On the contrary, when the pressure difference decreases, the valve opens automatically and the pressure difference remains constant. Self-operated pressure control valve, the automatic valve plug in the control range is off, the pressure drop across the valve exceeds the pre-set value, the valve plug automatically opens and automatically adjusts the opening degree under the action of the pressure-sensitive film to maintain the pressure at both ends of the valve The difference is relatively constant.
