What is the concept of balanced pneumatic valve

balanced pneumatic valve is under the working condition of hydraulic, pneumatic valve has dynamic and static balance adjustment. Such as: static balance pneumatic valve, pneumatic valve of dynamic balance.

static balance pneumatic valve which is also called the balancing pneumatic valve, manual pneumatic valve, digital locked balance valve, pneumatic valve on-off regulation, etc. , it is by changing the pneumatic valve core and valve seat clearance ( The opening) To change through the pneumatic valve flow resistance in order to achieve the purpose of flow adjustment, the role of the object is the resistance of the system, to the new water allocation proportion according to the design and calculation of balance, each branch in proportion to increase or decrease at the same time, still can meet the needs of the current climate under part load of traffic demand, have the effect of thermal equilibrium.

pneumatic valve can be divided into dynamic flow balance of dynamic balance of pneumatic valve, pneumatic valve dynamic differential pressure balance, their self-reliance type differential pressure control pneumatic valve, etc.

the dynamic flow balance pneumatic valve which is also called: self-reliance type flow control pneumatic valve, pneumatic valve, self-reliance type balance flow pneumatic valve, pneumatic valve automatic balance, etc. , it is according to the system operating mode ( Differential pressure) Changes and automatically changes the resistance coefficient and the differential pressure in a certain range, can be effectively controlled by flow to maintain a constant, namely when before and after pneumatic valve differential pressure increases, turn down automatically by the pneumatic valve action to keep the flow does not increase, on the other hand, the differential pressure, small pneumatic valve is automatic, flow according to remain constant, however, when the pressure difference is less than or greater than the scope of the normal work of the pneumatic valve, it cannot provide additional pressure head, after all, the pneumatic valve to open or close position flow is still set low or high can't control.

dynamic balance differential pressure pneumatic valve, also known as self-reliance type pneumatic valve, differential pressure controller, differential pressure control voltage variable synchronizer, pneumatic valve differential pressure balance, etc. , it is to use differential pressure effect to adjust the opening of pneumatic valves, used to the change of the pressure drop of the pneumatic valve core make up for the change of pipeline resistance, so that can keep the differential basic the same when conditions change, the flow of the principle of it is in a certain range, can be effectively controlled system of constant pressure difference control, namely when the system pressure difference increasing, by a pneumatic valve automatically shut distortions, it can ensure the controlled system pressure difference increasing, on the contrary, differential pressure, small pneumatic valve is automatic, differential pressure remains constant.

on its pneumatic valve, pressure difference control in the automatic control of pneumatic valve plug is closed, on both ends of the pneumatic valve differential pressure exceeds the set value, pneumatic valve plug automatically open and automatically adjust the opening under the action of a pressure sensitive film, pneumatic valve pressure difference on both ends is relatively constant.
