Izinto zevalvu yensimbi, idizayini, izidingo zokuhlola Izidingo ezijwayelekile zevalvu yensimbi
2022-11-21
Impahla yevalvu yensimbi, idizayini, izidingo zokuhlola Izidingo ezijwayelekile zamavalvu ensimbi Leli zinga licacisa ingcindezi nezinga lokushisa, izinto zokwakha, izidingo zokuklama, ukuhlolwa nokuhlola, ukuhlola nokumaka nokungonakalisi kanye nokulungiswa kwamavalvu ensimbi. Ngaphakathi kwamanani esigaba sokucindezela okulinganiselwe, isilinganiso esimaphakathi phakathi kwezilinganiso zezinga lokushisa esohlwini noma izilinganiso zengcindezi zinganqunywa ngokutolikwa ngomugqa. Kodwa kuma-valve ane-flanged, indlela yokufaka phakathi komugqa ayivunyelwe ukucacisa ingcindezi yamagama. Izinga lokushisa elihambisana nokucindezela okulinganiselwe izinga lokushisa elilinganiselwe lezindlu zokucindezela, okufana nezinga lokushisa eliphakathi kulo. I-1 Range Leli zinga licacisa ingcindezi nezinga lokushisa, izinto zokwakha, izidingo zedizayini, ukuhlolwa nokuhlolwa, ukuhlolwa kokumaka nokungonakali kanye nokulungiswa kwamavalvu ensimbi. Leli zinga lisebenza ezintweni ezisohlwini lweThebula 1. Umzimba ungaphonswa, ufojiwe futhi ushiselwe, ukuxhumana ekugcineni kungase kuphendulwe, kucushwe futhi kushiselwe, kanye namavalvu afakwe isiqeshana kanye nama-single-flanged. Leli zinga lisebenza ebangeni lamapharamitha we-valve: a) Ingcindezi yegama elithi PN16 ~ PN760 amavalvu, ingcindezi ebizwa ngokuthi i-PN760* ifanele ama-valve okuphela kokushisela; b) Usayizi wokuzisholo awukho ngaphezu kwe-DN125. I-valve yokugcina yokuxhuma ye-Flange kanye ne-butt welding exhuma i-valve yokugcina; c) Amavalvu okugcina ashiselwe kanye nama-valve okugcina anentambo anosayizi wokuzisholo ongadluli i-DN65: d) amavalvu okugcina anentambo anezinga lokushisa elilinganiselwe elingekho ngaphezu kuka-540℃ kanye nengcindezi engeqile ku-PN420; e) Amavalvu ajikayo anomfutho wegazi ongu-PN16~PN25, izinga lokushisa elilinganiselwe elingekho ngaphezu kuka-540℃ 2 Amadokhumenti ayizithenjwa ezivamile Imigomo kumadokhumenti alandelayo iba imigomo yaleli Zinga ngokubhekisela kuleli Zinga. Ezicashunweni ezinedethi, zonke izichibiyelo ezilandelayo (ngaphandle kwamaphutha) noma izichibiyelo azisebenzi kuleli Zinga, nokho, abathintekayo ezivumelwaneni ezingaphansi kwaleli Zinga bayakhuthazwa ukuthi bahlole ukusetshenziswa kwezinguqulo zala madokhumenti. Ezithenjwa ezingenasuku, izinguqulo zazo ziyasebenza kuleli zinga.
