Mawonekedwe a ulusi wonyezimira wachitsulo / socket welding globe valve
1. Ili ndi mawonekedwe ophatikizika, mawonekedwe okongola komanso njira yochepetsera. Mapangidwe ake: BB kapena WB;
2. Kusindikiza pamwamba kumapangidwa ndi chitsulo cha alloy kapena simenti carbide. Kugwirizana kwa zipangizo zosindikizira ndizomveka ndipo moyo wautumiki ndi wautali;
3. Disiki ya valve ndi conical, ndipo tsinde la valve limaperekedwa ndi chisindikizo chosinthika, ndi ntchito yabwino yosindikiza. Pamwamba pa tsinde la valve ndi nitrided, yomwe imakhala ndi kukana kwa dzimbiri komanso kukana kukangana. Kulongedza kumatenga graphite yosinthika, yokhala ndi chisindikizo chodalirika, ntchito yosinthika ndi kutsegula pang'ono ndi kutseka torque;
4. Miyezo yosiyanasiyana ya mapaipi ndi mawonekedwe olumikizira (monga kuwotcherera zitsulo, kuwotcherera matako ndi kulumikizana kwa ulusi) zitha kusankhidwa.
