Indlela yokusebenzisa i-valve ngendlela efanele kufanelekile ukuqoqa!

I-valve iyithuluzi elisetshenziselwa ukulawula indlela, ukucindezela nokugeleza koketshezi ohlelweni loketshezi.Kuyithuluzi elenza okuphakathi (uketshezi, igesi, impushana) kugeleze noma kume kumapayipi namathuluzi futhi akwazi ukulawula ukugeleza kwawo.I-valve iyingxenye yokulawula ebalulekile ohlelweni lokuthuthwa kwamanzi.
Ukulungiselela ngaphambi kokusebenza
Funda imiyalelo yokusebenza ngokucophelela ngaphambi kokusebenzisa i-valve.Ngaphambi kokusebenza, isiqondiso sokugeleza kwegesi kufanele sicace, futhi izimpawu zokuvula nokuvala i-valve kufanele zihlolwe.Hlola ukubukeka kwevalvu ukuze ubone ukuthi imanzi.Uma kunomswakama, kufanele omiswe;uma kukhona enye inkinga, kufanele isingathwe ngesikhathi, futhi akukho msebenzi wephutha ovunyelwe.Uma i-valve kagesi imisiwe isikhathi esingaphezu kwezinyanga ezingu-3, ​​i-clutch kufanele ihlolwe ngaphambi kokuqala, futhi i-insulation, i-steering kanye nesifunda sikagesi se-motor kufanele ihlolwe ngemva kokuqinisekisa ukuthi isibambo sisendaweni yezandla.
Indlela elungile yokusebenza kwe-valve yamanuwali
I-valve eyenziwa ngesandla iyi-valve esetshenziswa kakhulu, isondo layo lesandla noma isibambo siklanywe ngokuvumelana nezisebenzi ezivamile, kucatshangelwa amandla obuso bokuvala kanye namandla okuvala adingekayo.Ngakho-ke, i-lever ende noma isipanela eside asikwazi ukusetshenziswa ukunyakaza.Abanye abantu bajwayele ukusebenzisa isipanela, futhi kufanele basinake kakhulu.Lapho uvula i-valve, amandla kufanele azinzile ukuze agweme amandla amaningi, okwenza i-valve ivule futhi ivale.Amandla kufanele azinzile angabi nomthelela.Ezinye izingxenye zamavalvu anomfutho ophezulu wokuvula nokuvalwa komthelela zicabange ukuthi amandla okushayisana awalingani nalawo amavalvu ajwayelekile.
Lapho i-valve ivuliwe ngokugcwele, isondo lesandla kufanele lihlehliswe kancane ukuze lenze imicu iqine ukuze kugwenywe ukuxega nokulimala.Kumavalvu esiqu akhuphukayo, khumbula ukuma kwesiqu lapho sivuleke ngokugcwele futhi sivaleke ngokugcwele, ukuze ugweme ukushaya isikhungo esifile esiphezulu lapho sivuleke ngokugcwele.Kulula ukuhlola ukuthi ijwayelekile yini uma ivalwe ngokugcwele.Uma i-valve iwe, noma i-valve core seal phakathi kwemfucumfucu emikhulu eshumekiwe, ukuma kwesiqu se-valve kuzoshintsha.Indawo yokuvala i-valve noma ukulimala kwesondo lesandla.
Uphawu lokuvula i-valve: lapho i-groove engaphezulu kwesiqu se-valve ye-valve yebhola, i-valve uvemvane kanye ne-plug valve ihambisana nesiteshi, kubonisa ukuthi i-valve isendaweni evulekile egcwele;lapho isiqu se-valve sizungeziswa kwesokunxele noma kwesokudla ngo-90. I-groove i-perpendicular esiteshini, ebonisa ukuthi i-valve isendaweni evaliwe ngokugcwele.Enye i-valve yebhola, i-butterfly valve, i-valve yepulaki ene-wrench kanye nesiteshi esihambisanayo ukuze sivuleke, sime mpo ukuze sivale.Ukusebenza kwama-valve anezindlela ezintathu kanye nanezindlela ezine kuzokwenziwa ngokulandela amamaki okuvula, ukuvala nokuhlehla.Susa isibambo esisusekayo ngemva kokusebenza.
Indlela yokusebenza elungile ye-valve yokuphepha
I-valve yokuphepha iphumelele ukuhlolwa kwengcindezi kanye nokucindezela okuqhubekayo ngaphambi kokufakwa.Uma i-valve yokuphepha isebenza isikhathi eside, opharetha kufanele anake ukuhlola i-valve yokuphepha.Ngesikhathi sokuhlolwa, abantu kufanele bagweme i-valve yokuphuma kwe-valve yokuphepha, bahlole uphawu oluholayo lwe-valve yokuphepha, badonse i-valve yokuphepha ngesikrufu ngesandla, bayivule kanye ngesikhashana ukuze bakhiphe ukungcola futhi baqinisekise ukuguquguquka kwe-valve yokuphepha.
Indlela elungile yokusebenza kwe-valve yokudonsa
I-valve yokukhipha amanzi kulula ukuvinjwa ngamanzi nezinye izibi.Uma iqalwa, qala ngokuvula i-valve yokudonsa bese ukhipha ipayipi.Uma kukhona ipayipi le-bypass, i-valve ye-bypass ingavulwa ukuze isetshenziswe isikhathi esifushane.Ukuze i-valve yokudonsa ngaphandle kwepayipi yokudonsa kanye nepayipi ye-bypass, i-valve yokudonsa ingasuswa.Ngemuva kokuvula i-valve yokuvala, vala i-valve yokuvala, faka i-valve yokukhipha amanzi, bese uvula i-valve yokuvala ukuze uqale i-valve yokukhipha amanzi.
Ukusebenza okulungile kwe-valve yokunciphisa ingcindezi
Ngaphambi kokuqala i-valve yokunciphisa ukucindezela, i-valve ye-bypass noma i-valve yokudonsa kufanele ivulwe ukuze kuhlanzeke ukungcola epayipini.Ngemva kokugezwa kwepayipi, i-valve ye-bypass kanye ne-valve yokudonsa kuzovalwa, bese kuqalwa i-valve yokunciphisa umfutho.Kukhona i-valve yokudonsa ngaphambi kwe-valve yokunciphisa umfutho we-steam, okudingeka ivulwe kuqala, bese ivula kancane i-valve yokuvala ngemuva kwe-valve yokunciphisa ukucindezela, futhi ekugcineni ivule i-valve yokuvala phambi kwe-valve yokunciphisa ukucindezela. .Khona-ke, bheka ama-gauge okucindezela ngaphambi nangemva kwe-valve yokunciphisa ingcindezi, futhi ulungise isikulufu sokulungisa se-valve yokunciphisa ingcindezi ukuze wenze ingcindezi ngemuva kwe-valve ifinyelele inani elimisiwe.Bese uvula kancane i-valve yokuvala ngemuva kwe-valve yokunciphisa ingcindezi ukuze ulungise ukucindezela ngemuva kwevalvu kuze kube yenelisayo.Lungisa isikulufu sokulungisa bese uvala ikepisi yokuvikela.Ngokwesibonelo
Uma i-valve yokunciphisa ingcindezi ihluleka noma idinga ukulungiswa, i-valve ye-bypass kufanele ivule kancane, futhi i-valve yokusika phambi kwe-valve kufanele ivalwe ngesikhathi esifanayo.I-valve ye-bypass kufanele ilungiswe cishe ngesandla ukuze yenze ingcindezi ngemuva kwe-valve yokunciphisa ingcindezi iqine ngokuyisisekelo kunani elinqunywe kusengaphambili.Bese uvala i-valve yokunciphisa ingcindezi, uyishintshe noma uyilungise, bese ubuyela kokujwayelekile.
Ukusebenza kahle kwe-valve yokuhlola
Ukuze ugweme amandla omthelela aphezulu akhiwe ngesikhathi lapho i-valve yokuhlola ivaliwe, i-valve kufanele ivalwe ngokushesha, ukuze kuvinjelwe ukwakheka kwe-backflow velocity enkulu, okuyimbangela yokucindezela komthelela lapho i-valve ivalwa ngokuzumayo. .Ngakho-ke, isivinini sokuvala se-valve kufanele sihambisane nezinga lokuncishiswa komfula ongezansi ngendlela efanele.
Uma ububanzi besivinini sendawo ephakathi nendawo engezansi bukhulu, ijubane elincane alanele ukuphoqa ukuvala ukuthi kume ngokuqinile.Kulesi simo, ukunyakaza kwengxenye yokuvala kungavinjelwa yi-damper ngaphakathi kohlu oluthile lwe-stroke yayo yesenzo.Ukudlidliza okusheshayo kwezingxenye zokuvala kuzokwenza izingxenye ezihambayo ze-valve ziguge ngokushesha, okuholela ekuhlulekeni ngaphambi kwesikhathi kwe-valve.Uma okuphakathi kuwukugeleza kwe-pulsating, ukudlidliza okusheshayo kwengxenye yokuvala nakho kubangelwa ukuphazamiseka okuphakathi okwedlulele.Kulesi simo, i-valve yokuhlola kufanele ibekwe endaweni lapho ukuphazamiseka okuphakathi kuncane kakhulu.
