Ukuvula nokuvalwa kwe-valve ngesandla, amandla amakhulu
Umphumela: i-valve izolimala uma ilula, futhi ingozi yokuphepha izobangelwa uma inzima
Izinyathelo: I-valve yezandla, isondo layo lesandla noma isibambo, iklanyelwe ngokwabasebenzi abavamile, kucatshangelwa amandla okuvala uphawu namandla okuvala adingekayo. Ngakho-ke, akuvunyelwe ukuhamba nge-lever ende noma i-wrench ende. Abanye abantu bajwayele ukusebenzisa i-wrench, kufanele banake kakhulu, bangasebenzisi amandla amaningi, ngaphandle kwalokho kulula ukulimaza indawo yokuvala, noma ukuphula isondo lesandla nesibambo. Vula futhi uvale i-valve, amandla kufanele azinzile, angabi nomthelela. Ezinye izingxenye zama-valve anomfutho ophezulu wokuvula nokuvalwa komthelela zicubungule amandla omthelela futhi i-valve evamile ayikwazi ukulinda. Ukuze i-valve ye-steam, ngaphambi kokuvula, izoshiswa kusengaphambili futhi amanzi ahlanganisiwe azosuswa. Lapho ivula, izohamba kancane ngangokunokwenzeka ukuze igweme isando samanzi. Lapho i-valve ivuliwe ngokugcwele, buyisela isondo lesandla emuva kancane, ukuze izintambo ziqine ukugwema ukuxega nokulimala. Ukuze uthole ama-valve esiqu esivulekile, khumbula ukuma kwesiqu se-valve lapho ivuleke ngokugcwele futhi ivaleke ngokugcwele ukuze ugweme ukushaya indawo efile ephezulu lapho ivuleke ngokugcwele. Kulula ukuhlola ukuthi ijwayelekile yini uma ivalwe ngokugcwele. Uma ihhovisi le-valve liwa, noma i-sundry enkulu ishumekwe phakathi kwama-valve core seals, indawo ye-valve stem izoshintsha lapho i-valve ivalwe ngokugcwele. Lapho ipayipi lisetshenziswa okokuqala, kukhona ukungcola okuningi ngaphakathi, ngakho-ke i-valve ingavuleka kancane. Ukugeleza kwesivinini esikhulu se-medium kungasetshenziswa ukuyigeza, bese ivalwa kancane (ayikwazi ukuvalwa ngokushesha noma ngobudlova ukuze kuvinjwe ukungcola okusele ekulimazini indawo yokuvala). Ingavulwa futhi. Phinda izikhathi eziningi, hlanza ukungcola, bese ufaka ekusebenzeni okujwayelekile. Lapho i-valve ivame ukuvulwa, kungase kube nokungcola endaweni yokuvala. Uma ivaliwe, le ndlela engenhla izosetshenziswa ukuyigeza ihlanzeke, bese ivalwa ngokusemthethweni. Uma isondo lesandla nesibambo zonakalisiwe noma zilahlekile, kufanele zifaniswe ngokushesha, futhi azikwazi ukushintshwa yi-wrench eguquguqukayo, ukuze ugweme ukulimaza izinhlangothi ezine ze-valve stem nokwehluleka ukuvula nokuvala, okuholela ezingozini zokukhiqiza. . Kweminye imidiya, lapho ivalvu ivaliwe futhi ipholiswa ukuze ishwabe ivalvu, opharetha kufanele ayivale futhi ngesikhathi esifanele ukuze agcine indawo yokuvala ingenamithungo emihle. Uma kungenjalo, imidiya igeleza emithumeni emihle ngesivinini esikhulu futhi igugule kalula indawo yokuvala. Ngesikhathi sokusebenza, uma kutholakala ukuthi ukusebenza kunzima kakhulu, izizathu zizohlaziywa. Uma ukupakisha kuqinile kakhulu, kungaxegiswa kahle. Uma isiqu se-valve sitshekile, abasebenzi bazokwaziswa ukuthi basilungise. Kwamanye ama-valve, lapho evaliwe, izingxenye zokuvala ziyashiswa futhi zandiswe, okwenza kube nzima ukuvula; uma kufanele zivulwe ngalesi sikhathi, zingakhulula intambo yebhonethi ingxenye yesiyingi ukuze kuqedwe ukucindezeleka kwesiqu se-valve, bese behambisa isondo lesandla.
