I-valve iyithuluzi elisetshenziselwa ukulawula indlela, ingcindezi kanye nokugeleza koketshezi ohlelweni lwe-fluid, olungenza okuphakathi (uketshezi, igesi, impushana) kumapayipi namathuluzi kugeleze noma kumise futhi kulawule ukugeleza kwawo. I-valve iyingxenye ebalulekile yokulawula ohlelweni lokuthuthwa kwamanzi.
Ukulungiselela ngaphambi kokusebenza
Ngaphambi kokusebenzisa i-valve, funda imiyalelo yokusebenza ngokucophelela. Ngaphambi kokusebenza, qiniseka ukuthi uyazi isiqondiso sokugeleza kwegesi, futhi unake ukuhlola izimpawu zokuvula nokuvala ze-valve. Hlola ukubukeka kwevalvu ukuze ubone ukuthi imanzi. Uma imanzi, yomise; uma kutholakala ukuthi kunezinye izinkinga, zisingatheni ngesikhathi futhi ungasebenzi ngamaphutha. Uma ivalvu kagesi ingasebenzi isikhathi esingaphezu kwezinyanga ezi-3, hlola i-clutch ngaphambi kokuqala. Ngemuva kokuqinisekisa ukuthi isibambo sisesimweni semanyuwali, hlola ukufakwa, ukuqondisa kanye nomjikelezo kagesi wemoto.
Ukusebenza okulungile kwe-valve ye-manual
I-valve ye-manual iyi-valve esetshenziswa kakhulu. Isondo lesandla noma isibambo salo siklanywe ngokuvumelana nabasebenzi 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, ngakho-ke kufanele banake kakhulu. Lapho bevula i-valve, kufanele basebenzise amandla aqinile ukuze bagweme amandla amaningi, okuzobangela ukuvulwa nokuvalwa kwe-valve. Amandla kufanele azinzile futhi angathinteki. Ezinye izingxenye zama-valve anomfutho ophezulu wokuvula nokuvalwa komthelela zicabangele amandla okuthinta kanye ne-valve evamile akukwazi ukulingana enye nenye.
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. Ukulimala kwendawo yokuvala i-valve noma isondo lesandla se-valve.
Uphawu lokuvula i-valve: lapho i-groove engaphezulu kwenduku ye-valve ye-valve yebhola, i-valve ye-butterfly ne-plug valve ihambisana nesiteshi, kubonisa ukuthi i-valve isendaweni evulekile egcwele; lapho induku yevalvu izungeza 90 kwesokunxele noma kwesokudla. Lapho, i-groove i-perpendicular esiteshini, okubonisa ukuthi i-valve isendaweni evaliwe ngokugcwele. Amanye ama-valve amabhola, ama-butterfly valves nama-plug valves avuleka lapho isikrufu sihambisana nesiteshi, futhi avale lapho isikrufu sime mpo. Ama-valve anezindlela ezintathu kanye nanezindlela ezine kufanele asetshenziswe ngokulandela amamaki okuvula, ukuvala nokuhlehla. Susa isibambo esisusekayo ngemva kokusebenza.
