dn300 ductile ironvalavu yozungulira
The ductile iron round flap valve ndi valavu yanjira imodzi yomwe imayikidwa potuluka pa drainpipe kuti madzi azitha kugwira ntchito komanso kukhetsa madzi. Amagwiritsidwa ntchito kusefukira kapena kuyang'ana sing'anga, ndipo amathanso kugwiritsidwa ntchito pazovundikira shaft zosiyanasiyana. Malingana ndi mawonekedwe, chitseko chozungulira ndi chitseko chogwedeza cha square chimamangidwa. The ductile iron round flap valve imapangidwa makamaka ndi thupi la valavu, chivundikiro cha valve ndi chigawo cha hinge. Mphamvu yake yotsegula ndi yotseka imachokera ku kuthamanga kwa madzi ndipo sichifunikira ntchito yamanja. Kuthamanga kwa madzi mu valavu ya flap ndi yaikulu kuposa yomwe ili kunja kwa valavu, ndipo imatsegula. Apo ayi, imatseka ndikufikira kusefukira ndikusiya zotsatira.

Tianjin Tanggu Jinbin valavu Co., Ltd. unakhazikitsidwa mu 2004, ndi likulu mayina a yuan miliyoni 113, antchito 156, 28 malonda nthumwi za China, kuphimba kudera la mamita lalikulu 20,000 okwana, ndi mamita lalikulu 15,100 kwa mafakitale ndi maofesi. Ndi valavu wopanga chinkhoswe akatswiri R&D, kupanga ndi malonda, olowa-katundu ogwira kaphatikizidwe sayansi, mafakitale ndi malonda.
Kampaniyo tsopano ili ndi 3.5m of vertical lathe, 2000mm * 4000mm wotopetsa ndi makina ophera ndi zida zina zazikulu zopangira, zida zoyeserera zama valve zogwira ntchito zambiri komanso zida zingapo zoyesera.
