Self own differential pressure valve stem, the stem within the scope of semi-automatic plug for closed condition, differential pressure more than design fixed value on both ends of the valve, the valve plug semi-automatic open and semi-automatic adjusting opening under pressure sensitive film utility, to maintain the valve pressure difference on both ends are relatively fixed eternal. Q: on a balanced valve synopsis a: balancing valve is in the hydrodynamic conditions, dynamic and static balance adjustment valve. Dynamic differential pressure balance valve, also known as self-reliance type differential pressure valve stem, differential pressure stem, regulated variable synchronizer, differential pressure balance valve, etc. , it is to use the differential utility to adjust the opening of the valve, using the valve core to remedy the changes of the pressure drop of pipeline resistance changes, so that when conditions change can maintain pressure difference largely unchanged, the flow of the principle of it is in a certain range, the differential pressure can help to curb the controlled system fixed eternal, namely when the system pressure difference increasing, after the valve of semi-automatic shut distortions, it can be control system pressure difference increasing security, by contrast, when the differential pressure reduced hours, valve is semi-automatic, differential pressure remains fixed eternal. Also called dynamic flow balance valve: flow valve stem, self-reliance self-reliance type balancing valve, flow valve, semiautomatic balancing valve and so on, it is according to the system operating mode ( Differential pressure) Change and semi-automatic on drag coefficient, the differential pressure in a certain range, can help to stem flow through to maintain a constant, namely when before and after the valve pressure difference increased, after the valve of semi-automatic down action to maintain the flow does not increase, in contrast, when the differential pressure reduced hours, valve is semi-automatic, fixed flow according to remain forever, however, when the pressure difference is less than or greater than normal business scope of the valve, it can not supply the other head, at this point the valve down the whole piece of paper or seated position flow or higher or lower than the setting flow can't stem Marine valve. 。 Such as: static balancing valves and dynamic balancing valves. Dynamic balancing valve is divided into dynamic flow balance valve, dynamic differential pressure balance valve, self-reliance type differential pressure valve stem to itself. Static balancing valve is also called a balanced valve, balanced Industrial Valves manually, digital locked balance valve, two position regulator, etc. , it is after the change of valve core and valve seat space ( The opening) , to change the flow resistance of flow through the valve in order to achieve the purpose of the flow adjustment, its utility object is the resistance of the system, to the new water in accordance with the preset calculating equilibrium, the proportion of each branch in proportion to increase or decrease at the same time, is satisfied with the present climatology demand under part load flow needs, have the effect of thermal equilibrium. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
