进口德标隔膜阀主要性能 Main performance

1.气密好，无外部泄漏。阀体与盖被中间隔膜隔开，使得隔膜上方的阀盖、阀杆等零件不受介质侵蚀。而且无外部泄漏或外界空气进入污染流体 Good air tightness, no external leakage. The valve body and cover are separated by an intermediate diaphragm, ensuring that the valve cover, valve stem, and other parts above the diaphragm are not corroded by the medium. And there is no external leakage or external air entering the contaminated fluid

2.耐蚀性?耐化学性优异。通过橡胶、氟树脂等各种衬里阀体和丰富的隔膜材料相组合，可制造适合各种流体规格的阀，性价比优于特殊合金类材料 Excellent corrosion resistance and chemical resistance. By combining various lining valve bodies such as rubber and fluorine resin with rich diaphragm materials, valves suitable for various fluid specifications can be manufactured, with better cost-effectiveness than special alloy materials

3.隔膜与阀瓣接触，阀杆上、下运动并且通过阀瓣带动隔膜与屋脊接触以达到隔断通道的目的。隔膜与尾脊不接触时具有一定节流作用，行程短对隔膜挠变要求较低，无淤积介质的死角 The diaphragm is in contact with the valve disc, and the valve stem moves up and down, driving the diaphragm to contact the ridge through the valve disc to achieve the purpose of isolating the channel. When the diaphragm is not in contact with the tail ridge, it has a certain throttling effect, and a short stroke has lower requirements for diaphragm deflection, without dead corners of accumulated media
