旋啟式(shi)止(zhi)回閥

玫德集(ji)團旋啟式止回閥采(cai)用國外先進的結構設計，嚴(yan)格的制造工藝和高性(xing)能的材料(liao)，密(mi)封性(xing)可靠(kao)，操作輕快，維護簡單便利，使用壽(shou)命(ming)長。

旋啟式止回閥(fa)在管(guan)道系(xi)統(tong)(tong)(tong)(tong)中(zhong)通常(chang)用(yong)于防止介(jie)質的逆流，以保護重要設備的正常(chang)使用(yong)，廣泛用(yong)于生活用(yong)水系(xi)統(tong)(tong)(tong)(tong)、給排水系(xi)統(tong)(tong)(tong)(tong)、污水處理系(xi)統(tong)(tong)(tong)(tong)、灌溉、空調系(xi)統(tong)(tong)(tong)(tong)、消(xiao)防系(xi)統(tong)(tong)(tong)(tong)等(deng)(deng)管(guan)路系(xi)統(tong)(tong)(tong)(tong)及化工能源等(deng)(deng)工業。

產(chan)品特征：

眾多(duo)不同(tong)的(de)材料和(he)選(xuan)項(xiang)，適用(yong)于多(duo)種(zhong)應用(yong)
規格：DN 50至DN 600，2＂至24＂

法(fa)蘭連接(jie)按(an)照DIN EN、ANSI/ASME等標(biao)準
閥(fa)(fa)體、閥(fa)(fa)蓋和(he)閥(fa)(fa)瓣主體皆為(wei)球(qiu)墨鑄鐵材質，球(qiu)化率達到(dao)國際二級(ji)球(qiu)化水平，強度(du)高，抗腐蝕性能好

閥(fa)體(ti)輕，閥(fa)瓣啟閉行程短(duan)，流(liu)線型結構，流(liu)阻小(xiao)

關閉(bi)(bi)時間短(duan)，能(neng)夠實現速閉(bi)(bi)功能(neng)，節能(neng)效(xiao)果好
