Ukulungiselela ngaphambi kokusebenza
Ngaphambi kokusebenzisa i-valve, kufanele ufunde imiyalelo yokusebenza ngokucophelela. Ngaphambi kokusebenza, kufanele ucace mayelana nesiqondiso sokugeleza kwegesi, kufanele unake ukuhlola ukuvuleka kwe-valve nokuvala izimpawu. Hlola ukubukeka kwe-valve ukuze ubone ukuthi i-valve imanzi, uma kukhona umswakama okumele umiswe ukwelashwa; uma kutholakala ukuthi kunezinye izinkinga okufanele kubhekwane nazo ngesikhathi esifanele, ngeke zisetshenzwe ngokwehluleka. Uma i-valve kagesi ingasebenzi isikhathi esingaphezu kwezinyanga ezingu-3, i-clutch kufanele ihlolwe ngaphambi kokuqala, qiniseka ukuthi isibambo sisendaweni yesandla, bese uhlola ukuvala, ukuqondisa kanye nezintambo zikagesi zenjini.
Ukusebenza Okufanelekile Kwama-Valves Emanuwali
Ama-valve okwenziwa ngesandla ama-valve asetshenziswa kakhulu, futhi amasondo awo ezandla noma izibambo zakhelwe ngokuhambisana namandla omuntu avamile, kucatshangelwa amandla obuso bokuvala kanye namandla okuvala adingekayo. Ngakho-ke, awukwazi ukusebenzisa i-lever ende noma isandla eside ukuhambisa ipuleti. Abanye abantu bajwayele ukusetshenziswa kwesandla sepuleti, kufanele banake kakhulu ukuvulwa kwe-valve kufanele kusetshenziselwe ukuphoqa ubushelelezi, ukugwema amandla amaningi, okuholela ekuvuleni nasekuvaleni kwe-valve, amandla kufanele abe bushelelezi, angabi nomthelela. . Okunye ukuvulwa komthelela nokuvalwa kwezingxenye zamavalvu anengcindezi ephezulu kuye kwabhekwa njengalo mthelela futhi amavalvu ajwayelekile awakwazi ukulingana neGang.
Lapho i-valve ivuliwe ngokugcwele, i-handwheel kufanele iguqulwe kancane, ukuze izintambo phakathi kwe-tight, ukuze zingathukululi umonakalo. Ngobaama-valve esango elikhuphukayo,ukukhumbula i-stem evulekile ngokugcwele futhi ivaliwe ngokugcwele, ukugwema ukuvuleka ngokugcwele lapho umthelela endaweni efile. Futhi kulula ukuhlola ukuthi ijwayelekile yini uma ivalwe ngokugcwele. Uma ihhovisi le-valve livaliwe, noma uphawu lwe-spool lushumekwe phakathi kwemfucumfucu emikhulu, indawo ye-stem evalwe ngokugcwele kufanele ishintshwe. Ukulimala kwendawo yokuvala i-valve noma isondo lesandla se-valve.
I-valve uphawu oluvulekile: i-valve yebhola,i-valve ye-butterfly egxilile, ipulaki ye-valve stem top surface groove ehambisana nesiteshi, okubonisa ukuthi i-valve isendaweni evuleke ngokugcwele; lapho isiqu se-valve sizungeza ngo-90 ° kwesokunxele noma kwesokudla, i-groove i-perpendicular esiteshini, okubonisa ukuthi i-valve isendaweni evaliwe ngokugcwele. Amanye ama-valve ebhola, amavalvu ovemvane, xhuma ama-valve ukuze aklwebhe kanye nesiteshi sihambisane ukuze sivuleke, sime mpo ukuze sivalwe. Ama-valve anezindlela ezintathu, ezine-way-way kufanele asetshenziswe ngokuhambisana nokumakwa kokuvula, ukuvala nokuhlehla. Ngemuva kokuthi umsebenzi usuqediwe, isibambo esisuswayo kufanele sikhishwe.
Ukusebenza kahle kwama-valve okuhlola
Ukuze ugweme amandla omthelela aphezulu akhiwe ngesikhathi sokuvalai-valve yokuhlola i-rubber ehlezi, i-valve kumele ivalwe ngokushesha, ngaleyo ndlela ivimbele ukwakheka kwe-backflow velocity enkulu, okuyimbangela yokucindezela komthelela okwakhiwa lapho i-valve ivalwa ngokuzumayo. Ngakho-ke, isivinini sokuvala se-valve kufanele sihambisane kahle nezinga lokubola kwe-medium engezansi.
Uma isivinini se-medium egelezayo sihluka ebangeni elibanzi, ubuncane bejubane lokugeleza alanele ukuphoqa isici sokuvala ukuthi sime kancane. Kulesi simo, ukunyakaza kwesici sokuvala kungathungwa ngaphakathi kohlu oluthile lokushaywa kwayo. Ukudlidliza okusheshayo kwesici sokuvala kungabangela izingxenye ezihambayo ze-valve ukuthi ziguge ngokushesha, okuholela ekuhlulekeni kwe-valve ngaphambi kwesikhathi. Uma i-medium ishaya, ukudlidliza okusheshayo kwesici sokuvala nakho kubangelwa ukuphazamiseka okuphakathi okwedlulele. Noma ngabe lokhu kunjalo, ama-valve okuhlola kufanele abekwe lapho ukuphazamiseka okuphakathi kuncishisiwe.
