Magetsi valavu pachipata: ntchito, makhalidwe, ndi ntchito
Valve yamagetsi yamagetsi ndi valavu yoyenda yomwe imayenderana ndi Z-type multi turn actuator ndipo imabwera mumitundu yonse yakusintha komanso yanzeru. Valavu yamtunduwu ndi yosavuta kugwiritsa ntchito ndipo ndiyo yofala kwambiri yotsegula ndi kutseka valve, yomwe imagwiritsa ntchito mmwamba ndi pansi pa chipata kuti igwirizane ndi kutseka sing'anga yamadzimadzi mu payipi. Lili ndi ntchito zosiyanasiyana, kuphatikizapo mafakitale monga magetsi, zitsulo, mafuta, mankhwala, mapepala, ndi zimbudzi.
Zomwe zimapangidwa ndi mavavu amagetsi a wedge gate makamaka zimaphatikizapo mfundo izi:
1. Kukaniza kwamadzimadzi kumakhala kochepa, ndipo malo osindikizira sakhudzidwa kwambiri ndi kukokoloka ndi kukokoloka ndi sing'anga.
2. Ndiosavuta kutsegula, imakhala ndi ntchito yabwino yosindikizira, njira yopanda malire yapakati yothamanga, sichisokoneza kutuluka, ndipo sichichepetsa kupanikizika.
3. Ili ndi mawonekedwe osavuta, njira yabwino yopangira zinthu, ndi ntchito zosiyanasiyana.
Miyezo yophatikizira mavavu amagetsi a wedge yamagetsi ndi GB/T13927, JB/T 79, GB/T9113, GB/T 12224, GB/T12234, GB/T12221, HG/T20592, EN1092, ndi JB/T9092.
Pazinthu zazikuluzikulu zogwirira ntchito, mavavu amagetsi a wedge amagetsi ndi oyenera pazofalitsa zosiyanasiyana komanso kutentha. Mwachitsanzo, carbon zitsulo (C-mtundu) ndi oyenera madzi, nthunzi, ndi mafuta mankhwala, ndi kutentha kwabwino ≤ 425 ℃; Chromium faifi tambala zitsulo (P-mtundu) ndi oyenera asidi nitric, ndi kutentha oyenera ≤ 200 ℃; Chromium faifi tambala molybdenum zitsulo (R-mtundu) ndi oyenera asidi asidi, ndi kutentha oyenera ≤ 200 ℃; Chromium molybdenum chitsulo (Mtundu I) ndi oyenera madzi, nthunzi, ndi mafuta mankhwala, ndi kutentha kwabwino ≤ 550 ℃.
Zinthu zazikuluzikulu za ma valve olowera pachipata chamagetsi amaphatikiza thupi / chivundikiro, chipata / mpando, nati ya valavu, gudumu lamanja, ndi tsinde la valve. Kusankhidwa kwa zinthu za zigawozi kumatsimikiziridwa makamaka kutengera malo ogwirira ntchito ndi zinthu zapakati za valve kuti zitsimikizire kuti ntchito ndi moyo wa valve.
Ponseponse, mavavu amagetsi a wedge ndi othandiza, odalirika, komanso ma valve ochita zachuma omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
