Ukulungiselela ngaphambi kokuhlinzwa
Ngaphambi kokusebenzisa ivalvu, kufanele ufunde imiyalelo yokusebenza ngokucophelela. Ngaphambi kokusebenza, kufanele ucacise ukuthi igesi igeleza kanjani, kufanele uqaphele ukuhlola izimpawu zokuvula nokuvala ivalvu. Hlola ukubukeka kwevalvu ukuze ubone ukuthi ivalvu imanzi yini, uma kukhona umswakama ozokwenziwa ukwelashwa kokomisa; uma kutholakala ukuthi kunezinye izinkinga okufanele zixazululwe ngesikhathi, akufanele zisebenze ngokwehluleka. Uma ivalvu kagesi ingasebenzi isikhathi esingaphezu kwezinyanga ezintathu, i-clutch kufanele ihlolwe ngaphambi kokuqala, qiniseka ukuthi isibambo sisesimweni sesandla, bese uhlola ukufudumeza, ukuqondisa kanye nezintambo zikagesi zemoto.
Ukusebenza Okufanele Kwama-Valve Ezandla
Ama-valve esandla yiwona asetshenziswa kakhulu, futhi amasondo awo esandla noma izibambo zenzelwe ngokuhambisana namandla avamile omuntu, kucatshangelwa amandla okuvala kanye namandla okuvala adingekayo. Ngakho-ke, awukwazi ukusebenzisa i-lever ende noma isandla eside ukuhambisa ipuleti. Abanye abantu bajwayele ukusebenzisa ipuleti ngesandla, kufanele banake kakhulu ukuvulwa kwe-valve. Kufanele kusetshenziswe ukuphoqa ukushelela, ukugwema amandla amaningi, okuholela ekuvulekeni nasekuvalekeni kwe-valve, amandla kufanele abe bushelelezi, hhayi umthelela. Ukuvulwa nokuvalwa komthelela kwezinye izingxenye ze-valve ezinengcindezi ephezulu kuye kwabhekwa njengomthelela futhi ama-valve ajwayelekile awakwazi ukulingana ne-Gang.
Uma ivalvu ivuliwe ngokugcwele, isondo lesandla kufanele liguqulwe kancane, ukuze imicu phakathi kwayo iqine, ukuze ingawukhululi umonakalo.amavalvu esango lesiqu akhuphukayo,ukukhumbula indawo evulekile nevaliwe ngokuphelele lapho isiqu sibekwe khona, ukugwema ukuvuleka ngokuphelele lapho kuthinteka isikhungo esifile. Futhi kulula ukuhlola ukuthi kuyinto evamile yini uma ivaliwe ngokuphelele. Uma ihhovisi le-valve livaliwe, noma uphawu lwe-spool lufakwe phakathi kwemfucumfucu emikhulu, indawo yesiqu evaliwe ngokuphelele kufanele ishintshwe. Umonakalo ebusweni bokuvala i-valve noma isondo lesandla le-valve.
Uphawu oluvulekile lwevalvu: ivalvu yebhola,ivalvu yebhabhathane eliyindilinga, umsele wom ...
Ukusebenza kahle kwama-check valve
Ukuze kugwenywe amandla amakhulu okushaya akhiwe ngesikhathi sokuvalai-valve yokuhlola ehleli ngerabha, ivalvu kumele ivalwe ngokushesha, ngaleyo ndlela kuvinjelwe ukwakheka kwejubane elikhulu lokugeleza emuva, okuyimbangela yokucindezela komthelela okwakheka lapho ivalvu ivalwa ngokuzumayo. Ngakho-ke, ijubane lokuvala ivalvu kufanele lihambisane kahle nezinga lokubola kwe-medium engezansi komfula.
Uma ijubane le-medium egelezayo lihluka ebangeni elibanzi, ijubane elincane lokugeleza alanele ukuphoqa into yokuvala ukuthi ime kancane. Kulokhu, ukunyakaza kwento yokuvala kungancishiswa ngaphakathi kwebanga elithile lokushaya kwayo. Ukudlidliza okusheshayo kwento yokuvala kungabangela ukuthi izingxenye ezihambayo zevalvu ziguge ngokushesha kakhulu, okuholela ekwehlulekeni kwevalvu ngaphambi kwesikhathi. Uma i-medium ishaya ngamandla, ukudlidliza okusheshayo kwento yokuvala nakho kubangelwa ukuphazamiseka okukhulu kwe-medium. Noma ngabe yikuphi lapho kunjalo, ama-valve okuhlola kufanele atholakale lapho ukuphazamiseka okuphakathi kuncishiswa khona.
