2. Use: the new adjustable lower pressure valve installed in the city of one-way horzontally, can higher valve upstream ( Imports) Pressure to meet use requirement downstream ( Export) Pressure, no matter how upstream pressure Marine valves and flow changes, setting good downstream pressure maintain fixed eternal unchanged. When the main valve opens, media of exports also after a pilot valve to the main valve cavity on the diaphragm chamber, make the main valve plate mouth highly reliable in a value, so the valve after pressure is fixed eternal. Stem line by the gate valve, filter, pressure gauge, of piping accessories. The main Industrial Valves consists of body, diaphragm, cover, diaphragm, the valve stem, valve plate and other major parts. 。 Pressure feedback system composed of pilot valve assembly and stem line. After a pilot Industrial Valves to form independent pressure feedback system, and using the hydraulic principle of stem, outlet pressure is not affected by the influence of inlet pressure and flow rate changes, can reduce dynamic pressure, can reduce static pressure again. C, large caliber, for the nation's largest so far lower pressure valve. E, can replace the middle pool, pool of land surface or the size of the object surface, to prevent the secondary pollution of water quality. 4. Technical parameter: a, nominal pressure: 1. 0 mpab, outlet pressure: PN1. 0 mpa adjusting range 0. 1MPa— 0. 8 mpac, suit to use media: raw water, water: d, medium temperature 0 ℃ - 80℃　　5. Unique place: a, decreased the new adjustable pressure valve's adjustment, reduce the pressure and voltage stabilizing effect is good. D, body sees fit and use streamlined wide-body presupposition, flow capacity, resistance losses small. When the outlet pressure increases, media after pressure feedback system on the main valve cavity pressure increases, the main valve of the inferior vena stress equilibrium was mutilated, the opening of the valve value decreases, and the after mouth growth medium velocity and kinetic energy change lead to pressure loss, valve after pressure reduction. 3. Structure: the decreasing of the new adjustable pressure valve by the main valve, pressure feedback system, stem line. B, protection and convenient operation, only need to adjust the pilot valve adjusting screw, can make very accurate and reliable outlet pressure, key parts that fit and use high quality material, do not need to protect. Q: adjustable water with lower pressure valve principle of answer: 1. Adjustable water with lower pressure valve principle: reduce the pressure valve outlet pressure by adjusting screw on the pilot valve stem, it is coordinated with the needle valve on the pilot valve operation, a but beginning and end of the valve pressure was maintained after setting are fixed constants for eternity. , by contrast, when the valve after pressure relief, the increase of the opening of the main valve plate, valve after pressure. 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.
