( 6) According to the Numbers on the handwheel transferred to calculate the valve opening, and balance the next unit. ( 3) Seizing all the air filter device and remove them completely system. ( 2) Install the valve in order to guarantee the very accuracy of the flow rate, in equilibrium with a certain length of straight pipe before and after valve, and flow direction and the direction of arrow remain exactly the same. ( 5) Bring balance valve the flow input procedure of computer, digital surveying other balance valve were replicated inside the unit before, every input after all valve flow inside the unit, calculate the chance to calculate each of the balanced valve opening. Q: balanced valve regulating installation way of answer: ( 1) Workshop drawings, before install the valve to confirm main, riser and branch pipe, and facilities, the system is divided into units, confirm the balanced valve flow and mark on the drawing, the main of the preset flow rate is equal to the sum of branch pipe the preset flow. Marine valve ( 4) Open all should open the shutoff valves and open all stem valves, and then choose any unit, choose any balanced valve, in a unit of using digital type reconnaissance survey of computer under the existing valve opening pressure difference; Survey of the valve is closed, and the pressure difference, and then the valve from the new open to in situ. 。 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.
