Inkqubo yokusebenzisa ivalvu ikwayinkqubo yokuhlola nokuphatha ivalvu. Nangona kunjalo, le micimbi ilandelayo kufuneka iqwalaselwe xa kusetyenziswa ivalvu.
①Ivalvu yobushushu obuphezulu. Xa ubushushu bunyuka ngaphezu kwama-200°C, iibholithi ziyafudunyezwa kwaye zinde, nto leyo elula ukwenza ivalvu ivaleleke. Ngeli xesha, iibholithi kufuneka "ziqiniswe ngobushushu", kwaye akufanelekanga ukwenza ivalvu ivalwe ngokupheleleyo, ukuze kuthintelwe ukuba isiqu sevalvu singafi kwaye kube nzima ukuyivula kamva.
②Kwixesha lonyaka apho ubushushu bungaphantsi kwe-0℃, qaphela ukuvula iplagi yesihlalo sevalvu yeevalvu ezithintela umphunga namanzi ukuze kususwe amanzi aqukunjelweyo namanzi aqokelelweyo, ukuze kuthintelwe ukubanda nokuqhekeka kwevalvu. Nikela ingqalelo ekugcinweni kobushushu kweevalvu ezingenakususa ukuqokelelana kwamanzi kunye neevalvu ezisebenza ngamaxesha athile.
③ I-packing gland akufuneki icinezelwe kakhulu, kwaye ukusebenza okuguquguqukayo kwe-valve stem kufanele kuphumelele (akulunganga ukucinga ukuba okukhona i-packing gland iqinile, kokukhona ingcono, iya kukhawulezisa ukuguguleka kwe-valve stem kwaye yonyuse i-torque yokusebenza). Phantsi kwemeko yokungabikho kweendlela zokukhusela, i-packing ayinakutshintshwa okanye yongezwe phantsi koxinzelelo.
④Ngexesha lotyando, izinto ezingaqhelekanga ezifumaneka ngokumamela, ukuvumba, ukubona, ukuchukumisa, njl.njl. kufuneka zihlalutywe ngononophelo ngezizathu, kwaye ezo zisezisombululo zazo mazisuswe ngexesha elifanelekileyo;
⑤ Umqhubi kufuneka abe nencwadi yerekhodi ekhethekileyo okanye incwadi yerekhodi, kwaye anikele ingqalelo ekubhaleni ukusebenza kweevalvu ezahlukeneyo, ingakumbi ezinye iivalvu ezibalulekileyo, iivalvu ezinobushushu obuphezulu kunye noxinzelelo oluphezulu kunye neevalvu ezikhethekileyo, kubandakanya nezixhobo zazo zokudlulisa. Kufuneka kuqatshelwe ukusilela, unyango, iindawo zokutshintshwa, njl.njl., ezi zixhobo zibalulekile kumqhubi ngokwakhe, kubasebenzi bokulungisa kunye nomenzi. Misela irekhodi ekhethekileyo eneembopheleleko ezicacileyo, eziluncedo ekuqiniseni ulawulo.
