When entering the diaphragm ( The piston) Upper stem indoor pressure downstream of the water is discharged into atmosphere, or low pressure area, low utility in the disc and below the diaphragm of the pressure value is greater than at the top of the pressure value, thus pushing the main valve disc to rev. The location of the full paper: when entering the diaphragm ( The piston) Upper stem indoor pressure value in the inlet pressure and export since the middle, the main valve disc is to adjust status, adjust the position is determined by the needle valve in the duct system and pilot valve to the conjugate. 。 Have said above, the special nature of the valve near the valve disc movement speed, not prone to boil the water hammer shock, close to full close when the valve less quickly, the better, so the throttle device can be installed on the disc. It consists of a main valve and attached setting catheter, Marine valve, needle valve, ball valve and pressure gauge, etc, on the basis of using the target, function of place, can reduce pressure becomes remote sensing floating ball valve, valve, slow close check valve, flow stem, relief valve, water power electric stem valves, tight shutoff valves, etc. Additional pilot valve throttle and local to try our best to prevent Settings, small-bore orifice, avoid congestion. Pilot valve with the medium of liquid level and pressure changes [ 1] And action, because the pilot valve category is numerous, can be used alone or combined several applied, can make the main Industrial Valves in the water and water pressure and flow rate of single and compound adjustment function. Roughly similar to the main valve body by the valve, the valve when the whole paper, the pressure loss is much larger than the other valves, and all the more opening loss coefficient and near full close condition, the surge in the front of the valve diameter is larger, the more significant. Q: the principle of hydrodynamic stem valves and construct a hydrodynamic stem valve based on pressure pipeline media power, execute, regulating valve opening and closing. Indispensable to add filter net, regular check repair and set the by-pass pipe. Intermediate partition membrane type and hydrodynamic stem valve piston type two kinds, office principle is the same, is more than the downstream pressure difference, pilot valve stem, make diaphragm ( The piston) Hydraulic differential operation, the absolute by hydrodynamic semi-automatic adjustment, so that the main valve disc and complete paper or absolute closed or in the condition adjustment. 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.
