Hydrodynamic stem can discharge valve + 羭 enough, can lead to solidification and Marine Industrial Valves discharge water, reduce the heat rate of heating facilities. Q: hydrodynamic stem valve accurately answer: selection of hydrodynamic stem valve is a hydraulic valve stem, it consists of a main valve and set the catheter, pilot valve, needle valve, ball valve and pressure gauge, etc. 。 Selects the hydrodynamic stem valve, be sure to press always steam consumption per hour multiplied by the ratio 2 - For maximum frozen water, 3 times to selection of hydrodynamic stem valve displacement. Using hydrodynamic stem valves, the first thing to pay attention to the selection. So be on the basis of differential pressure of work choose hydrodynamic stem valve displacement. When choosing hydrodynamic stem valves, can not choose to nominal pressure hydrodynamic stem valve, because the nominal pressure can only express the hydrodynamic stem body shell pressure level, hydrodynamic stem Industrial Valves is the difference between the nominal pressure and work pressure is very big. Office differential pressure refers to the hydrodynamic stem office minus the hydrodynamic pressure before the valve stem valve export back pressure difference. Selection of hydrodynamic stem valve requirements without error correct vapor barrier drainage, acuity degree is high, can increase the utilization rate of steam, not leaking steam, office performance is reliable, high back pressure rate, use fixed number of year of the survival of length, convenient maintenance is preferred. Ability to guarantee the hydrodynamic stem valves while driving as far as possible to speed up the discharge frozen water, a sudden increase the temperature of the heating facilities. Selection is not appropriate, can lead to resistance and water leakage phenomenon. 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.
