Then office principle of flow valve stem what? Digital flow valve stem its Marine valve structure is composed of semi-automatic valve core, manual valve core and show local component. 。 Impact by water flow through the valve, water flow movement within the impeller, the impeller rotating and sensing transmission induction, the sensor sends out the electrical signal is proportional to the flow, traffic signals through a wire into electronic calculator, through the calculation of the calculator, micro disposer after disposal, the flow value. Manual valve core is used to regulate traffic, on the basis of values to set the desired flow value. Its office is and its complex. Semi-automatic valve core is used to keep the traffic forever fixed, namely in the pipe network pressure changes, semi-automatic valve core will be under the effect of pressure on small semi-automatic on high heat off valve mouth to keep setting flow number has not changed. Q: traffic stem office principle a: valve stem valve is the valve the preset flow, a new product research and development, production, and was called 400 x flow Industrial Valves stem, is a kind of right and use high precision guide form multifunctional valve stem flow. Show local by flow valve movement, sensors, transmission device, electronic calculator show local component. Suitable for use in water distribution to stem in pipeline flow and pressure, to maintain the prescribed flow unchanged, will limit excessive flow in a specified value in advance, and appropriate to the upstream pressure is reduced, even if the main valve upstream of the pressure change, also won't affect the main valve downstream of the flow. 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.
