Inqubo yokusebenzisa ivalvu iphinde ibe inqubo yokuhlola nokuphatha ivalvu. Kodwa-ke, izinto ezilandelayo kufanele ziqashelwe lapho kusetshenziswa ivalvu.
①Ivalvu yokushisa okuphezulu. Uma izinga lokushisa likhuphuka ngaphezu kwama-200°C, amabhawodi ayashiswa futhi ande, okulula ukwenza i-valve seal ikhululeke. Ngalesi sikhathi, amabhawodi kudingeka “aqiniswe ngokushisa”, futhi akufaneleki ukwenza i-hot-tightening endaweni evaliwe ngokuphelele yevalvu, ukuze kugwenywe ukuthi isiqu sevalvu singafi futhi kube nzima ukusivula kamuva.
②Ngesizini lapho izinga lokushisa lingaphansi kuka-0℃, qaphela ukuvula ipulaki yesihlalo sevalvu yamavalvu avimba umusi namanzi ukuze kususwe amanzi ahlanganisiwe namanzi aqongelelekile, ukuze kugwenywe ukubanda nokuqhekeka kwevalvu. Qaphela ukugcinwa kokushisa kwamavalvu angakwazi ukuqeda ukuqongelelana kwamanzi namavalvu asebenza ngezikhathi ezithile.
③ I-packing gland akufanele icindezelwe kakhulu, futhi ukusebenza okuguquguqukayo kwe-valve stem kufanele kunqobe (akulungile ukucabanga ukuthi uma i-packing gland iqinile, kungcono, izosheshisa ukuguguleka kwe-valve stem futhi yandise i-torque yokusebenza). Ngaphansi kwesimo sokungabi nazinyathelo zokuzivikela, i-packing ayikwazi ukushintshwa noma ukungezwa ngaphansi kwengcindezi.
④Ngesikhathi sokuhlinzwa, izinto ezingavamile ezitholakala ngokulalela, ukuhogela, ukubona, ukuthinta, njll. kufanele zihlaziywe ngokucophelela ngezizathu, futhi lezo ezingezona izixazululo zazo kufanele zisuswe ngesikhathi;
⑤ Umqhubi kufanele abe nencwadi yokurekhoda ekhethekile noma incwadi yokurekhoda, futhi aqaphele ukurekhoda ukusebenza kwamavalvu ahlukahlukene, ikakhulukazi amanye amavalvu abalulekile, amavalvu okushisa okuphezulu kanye nomfutho ophezulu kanye namavalvu akhethekile, kufaka phakathi amadivayisi awo okudlulisa. Kufanele kuqashelwe ukwehluleka, ukwelashwa, izingxenye zokufaka esikhundleni, njll., lezi zinto zibalulekile kumqhubi uqobo, kubasebenzi bokulungisa kanye nomkhiqizi. Misa i-log ekhethekile enemithwalo yemfanelo ecacile, ezuzisayo ekuqiniseni ukuphathwa.
