德国top托普进口底阀概述： 德国top托普进口底阀由阀体、阀盖、阀瓣、密封圈和垫片等部件组成，底阀的阀瓣有单瓣、双瓣和多瓣等几个类型。底阀在接入管路后，液体介质从阀盖方向进入阀体，液体的压力作用于阀瓣，使得阀瓣被打开允许介质流过，当阀体内的介质压力变化或消失时，阀瓣关闭阻止介质倒流。底阀实际上作用与止回阀作用相同，作用是防止水倒流。 德国托普进口底阀是一种节约能源的阀，一般安装在水泵水下吸管的底端，限制水泵管内液体返回水源,起着只进不出的功能。阀盖上有很多个进水口和加强筋,起到了不易堵塞，主要应用在抽水的管路上。 德国top托普进口可不锈钢底阀技术参数： 阀体材料：wcb、304、316 阀门口径：dn15-250mm 阀门压力：pn6-pn16 连接标准：asme b16.10、din2501 控制方式：自动 密封材料：304 工作温度：-20℃至+450℃ 德国top托普进口不锈钢底阀应用领域： 水、污水、油品等 germany top valve top import overview: germany imported top top end of the valve body, valve cover, valve, seals and gaskets and other parts, single or double valve and valve type valve flap valve etc.. at the end of the valve in the access pipe, the liquid medium from the direction of the valve cover into the valve, the fluid pressure acting on the valve, the valve was opened to allow the medium flow through the valve body, when the medium pressure change or disappear when the valve shut down to prevent the media back. at the end of the valve and check valve in the same role, is to prevent backflow of water. germany imported top bottom valve is a valve of energy conservation, water pump is usually installed in straw under the bottom limit of the liquid return pipe water pump, into play not only the function. there are many water intakes and stiffeners on the valve cover, which are not easy to jam. they are mainly used in pumping pipes. germany imported top stainless steel valve technology parameters can be top: body material: wcb, 304, 316 valve bore: dn15-250mm valve pressure: pn6-pn16 connection standards: asme, b16.10, din2501 control mode: automatic sealing material: 304 operating temperature: -20 deg c to +450 germany imported stainless steel valve top top application: water, sewage, oil, etc su wen bin (苏文宾） please do not hesitate to contact me if you need any further clarifications ; 3202186864 mobile phone : (同号） company phone :021-64387268 add : 上海徐汇区龙漕路51弄
