Ikambiso yokusebenzisa i-valve nayo yindlela yokuhlola nokuphatha i-valve. Kodwana, izinto ezilandelako kufanele zitjhejwe lokha nakusetjenziswa ivalvu.
Ivalvu yokutjhisa okuphezulu. Lokha izinga lokutjhisa nalikhuphuka ngaphezu kwama-200°C, amabhawudo ayafuthumala begodu abe made, okulula ukwenza bona isivalo sevalvu sikhululeke. Ngalesisikhathi, amabhawudo kufuze "aqiniswe ngokutjhisa", begodu akukafaneli ukwenza ukuqiniswa ngokutjhisa endaweni evaliweko ye-valve, ukwenzela bona kugwenywe isiqu se-valve bona singafi begodu kube budisi ukusivula ngokukhamba kwesikhathi.
②Ngesikhathi lapho amazinga womtjhiso angaphasi kwe-0°C, tjheja ukuvula ipulagi yesihlalo sevalvu yamavalvu amisa umtjhiso namanzi ukususa amanzi ahlanganisiweko namanzi abutheleleko, ukwenzela bona ugweme ukuqanda nokuqhekeka kwevalvu. Tjheja ukulondolozwa komtjhiso wamavalvu angakwazi ukuqeda ukubuthelela kwamanzi kanye namavalvu asebenza ngezikhathi ezithileko.
Indlala yokupakisha akukafaneli igandelelwe khulu, begodu ukusebenza okuguquguqukako kwesiqu sevalvu kufanele kunqobe (akukalungi ukucabanga bona lokha indlala yokupakisha nayiqinileko, kungcono, kuzokurhabisa ukuguga kwesiqu sevalvu begodu kwandise i-torque yokusebenza). Ngaphasi kobujamo bokungabi namagadango wokuvikela, ukupakisha angeze kwathathelwa indawo nofana kufakwe ngaphasi kwengcindezi.
④Ngesikhathi sokuhlinzwa, izehlakalo ezingakajayeleki ezitholakala ngokulalela, ukuhogela, ukubona, ukuthinta, njll. kufanele zihlaziywe ngokutjheja ngebanga, begodu lezo ezisezisombululweni zazo kufanele ziqedwe ngesikhathi;
Umsebenzisi kufanele abe nebhuku elikhethekileko lokuloba nofana ibhuku lamarekhodi, begodu atjheje ukurekhoda ukusebenza kwamavalvu ahlukahlukeneko, khulukhulu amanye amavalvu aqakathekileko, amavalvu womtjhiso aphezulu kanye namavalvu akhethekileko, kufaka hlangana iinsetjenziswa zawo zokudlulisa. Kufanele kuqashelwe ukwehluleka, ukwelashwa, ukubuyiselwa kweengcenye, njll., izinto lezi ziqakathekile kumsebenzisi ngokwakhe, abasebenzi bokulungisa kanye nomenzi. Yenza ilogo ekhethekileko enemisebenzi ecacileko, okuzuzisa ukuqinisa ukuphathwa.
