國內外的2W水用黃銅、不銹鋼電磁閥從原理上分為三大類（即：直動式、分步直動式、先導式），而從閥瓣結構和材料上的不同與原理上的區別又分為六個分支小類（直動膜片結構、分步重片結構、先導膜式結構、直動活塞結構、分步直動活塞結構、先導活塞結構)，按照氣路數分為2位2通，2位3通，2位4通，2位5通。2W water brass, stainless steel solenoid valves are suitable for water or liquid as the working medium, can be automated controls or protozoa control of water, oil, liquids and other working medium pipe off. 2W water brass, stainless steel solenoid valve As the rubber seal, so the cleaning medium is greatly reduced, with open and close rapidly, reliability, and other characteristics.
Valve Co., Ltd. Shanghai Zhi wide water solenoid valve works as follows: the open water for the second pilot valve solenoid valve, the structure is dominated by the pilot valve and the main valve solenoid valve, the main valve with rubber seal structure. Chang position, the movable core sealed pilot valve port, valve chamber pressure balance, closing the main valve port. When the coil is energized, the electromagnetic force generated on the active core pull, the main valve cavity medium leakage from the pilot valve port, as well as a pressure differential, diaphragm or valve cup was quickly lifted, opening the main valve to open, the valve will show passage of the. When the coil power, the magnetic field disappeared, moving core reset, closing the pilot valve opening, after the pilot valve and the main valve cavity pressure balance valve and was closed.
