Zogulitsa:
1. Thupi limapangidwa ndi chitsulo chapamwamba cha nodular cast iron, chomwe chimachepetsa kulemera kwa 20% mpaka 30% poyerekeza ndi valve yachipata yachikhalidwe.
2. Mapangidwe apamwamba a ku Ulaya, kapangidwe koyenera, kuyika bwino ndi kukonza.
3. Disiki ya valve ndi screw idapangidwa kuti ikhale yopepuka komanso yothandiza, ndipo torque yotseka ndi yaying'ono, yomwe ili pafupi ndi 50% yotsika kuposa momwe zimakhalira.
4. Pansi pa valavu yachipata imagwiritsa ntchito mawonekedwe apansi-pansi monga chitoliro chochepa, ndipo ikatsekedwa, kuthamanga kwachangu kumathamanga ndikutsuka zinyalala popanda kuwononga chivundikiro cha valve ndikuyambitsa nyama.
5. The vavu chimbale utenga apamwamba mphira wa kumwa madzi muyezo encapsulation wonse.Ukadaulo wotsogola wa rabara umathandizira kuti vulcanized valve disc iwonetsetse miyeso yolondola ya geometric, ndipo mphira ndi ma ductile castings amakhala ndi zomatira zolimba, zosavuta kugwa komanso kukhala ndi kukhazikika bwino.
6. Thupi la valve limapangidwa ndi kuponyedwa kwapamwamba, ndipo miyeso yolondola ya geometric imapangitsa kuti miyeso yoyenera ya thupi la valve isindikizidwe kwathunthu.
Kufotokozera Mwatsatanetsatane:
RV (H, C, R) X chipata valavu ndi mtundu wa zotanuka mpando kusindikiza chipata ndi encapsulation yofunika ya chimbale.Valavu ili ndi ubwino wosinthira kuwala, kusindikiza kodalirika, kosavuta kudziunjikira zinyalala, kukana dzimbiri, kulibe dzimbiri, komanso kukumbukira bwino kwa rabara.Itha kugwiritsidwa ntchito kwambiri mumitundu yosiyanasiyana yamadzi ndi mapaipi otulutsa ngati zotsekera kapena zowongolera.
ukadaulo parameter:
Zogwiritsidwa ntchito: ductile iron
Kukula: DN50mm ~DN600mm
Kupanikizika kwamphamvu: 1.0 MPa ~ 2.5MPa
Kutentha: -10 ℃—80 ℃
Ntchito sing'anga: madzi oyera, zimbudzi
Gwiritsani ntchito nthawi:
Valavu yokhala ndi chisindikizo chapampando ndiyoyenera kuthira madzi ambiri ndi ngalande, Kutentha kwa HVAC ndi mpweya wabwino, zozimitsa moto ndi ulimi wothirira.
