I-valve uvemvane womoyayakhiwe nge-actuator yomoya kanye nevalve uvemvane.I-valve uvemvane womoya isebenzisa ipuleti levemvane eliyindilinga elizungeza nesiqu se-valve ukuze livuleke futhi livalwe, ukuze kubonakale isenzo sokuvula.I-valve ye-pneumatic isetshenziswa ngokuyinhloko njenge-valve yokuvala, futhi ingabuye iklanywe ukuba ibe nomsebenzi wokulungisa noma i-valve yesigaba nokulungiswa.Njengamanje, i-valve ye-butterfly isetshenziswa ekucindezelweni okuphansi futhi enkulu Isetshenziswa ngokuqhubekayo kumapayipi aphakathi nendawo.
Umgomo wokusebenza weI-valve ye-butterfly ye-pneumatic
Ipuleti uvemvane we valve uvemvane ifakwe ohlangothini ububanzi iphayiphi.Kusiteshi esiyisilinda somzimba we-valve uvemvane, ipuleti uvemvane okumise okwediski lizungeza i-eksisi, futhi i-engeli yokuzungeza iphakathi kuka-0.°-90°.Lapho ukujikeleza kufinyelela ku-90°, i-valve isesimweni esivuleke ngokugcwele.I-valve yevemvane ilula ngesakhiwo, incane ngosayizi futhi ilula ngesisindo, futhi iqukethe izingxenye ezimbalwa kuphela.Ngaphezu kwalokho, ingavulwa ngokushesha futhi ivalwe ngokuzungezisa okungu-90 kuphela°, futhi ukusebenza kulula.Ngesikhathi esifanayo, i-valve inezici ezinhle zokulawula uketshezi.Lapho i-valve uvemvane isendaweni evuleke ngokugcwele, ukujiya kwepuleti uvemvane kuwukuphela kokumelana lapho okuphakathi kugeleza emzimbeni we-valve, ngakho-ke ukwehla kokucindezela okukhiqizwa i-valve kuncane kakhulu, ngakho kunezici ezinhle zokulawula ukugeleza.Ama-valve ovemvane anezinhlobo ezimbili zokuvala: uphawu olunwebekayo kanye nophawu lwensimbi.Kumavalvu okuvala anwebekayo, indandatho yokuvala ingashumeka emzimbeni wevalvu noma ixhunywe kuma-periphery wepuleti lovemvane.
I-valve uvemvane womoyaukulungiswa nokulungisa iphutha
1. Uhlelo lokuhlola isilinda nokulungisa
Ngokuvamile yenza umsebenzi omuhle wokuhlanza ubuso be-cylinder futhi ugcobe i-circlip ye-cylinder shaft.Vula ikhava yokugcina yesilinda njalo ngemva kwezinyanga eziyisi-6 ukuze uhlole ukuthi akhona yini ama-sundries kanye nomswakama kusilinda, kanye nesimo samafutha.Uma amafutha okugcoba eshoda noma omile, kuyadingeka ukuqaqa isilinda ukuze sigcinwe kahle futhi sihlanzwe ngaphambi kokwengeza amafutha okugcoba.
2. Ukuhlolwa komzimba we-valve
Njalo ezinyangeni eziyisi-6, hlola ukuthi ukubukeka komzimba we-valve kuhle, ukuthi kukhona ukuvuza ku-flange ekhuphukayo, uma kufaneleka, hlola ukuthi uphawu lomzimba we-valve luhle, alugqoki, noma ngabe ipuleti ye-valve iyaguquguquka, nokuthi ngabe kukhona yini udaba lwangaphandle olubhajwe kuvalvu.
I-cylinder block disassembly nezindlela zokuhlanganisa nezindlela zokuphepha:
Okokuqala khipha isilinda emzimbeni we-valve, qala ususe isembozo emikhawulweni yomibili yesilinda, unake isiqondiso se-piston rack lapho ususa i-piston, bese usebenzisa amandla angaphandle ukuzungezisa i-cylinder shaft ngokwewashi ukuze wenze ipiston igijime ohlangothini olungaphandle, bese uvala i-valve Imbobo ingena umoya kancane futhi i-piston iphushwa ngaphandle kancane ngomfutho womoya, kodwa le ndlela kufanele inake ukuze ikhiphe umoya kancane, ngaphandle kwalokho i-piston izokhipha ngokuzumayo, okuyingozi kancane!Bese ususa i-circlip ku-cylinder shaft, futhi i-cylinder shaft ingavulwa ukusuka komunye umkhawulo.khipha.Khona-ke ungakwazi ukuhlanza ingxenye ngayinye bese wengeza amafutha.Izingxenye ezidinga ukugcotshwa yilezi: udonga lwangaphakathi lwesilinda kanye nendandatho ye-piston seal, i-rack neringi yangemuva, kanye ne-gear shaft kanye nendandatho yokuvala.Ngemuva kokugcoba amafutha, kufanele afakwe ngokulandela i-oda lokudilizwa kanye nokuhleleka okuphambene kwezingxenye.Ngemuva kwalokho, kufanele ifakwe ngokuya nge-oda lokudilizwa kanye nokuhleleka okuphambene kwezingxenye.Naka ukuma kwegiya ne-rack, futhi uqinisekise ukuthi i-piston ishwabana ibe yindawo lapho i-valve ivuliwe.I-groove engaphezulu ekugcineni kwe-gear shaft ihambisana ne-cylinder block ngesikhathi sokuma kwangaphakathi, futhi i-groove esekupheleni kwe-shaft yegiya i-perpendicular ku-cylinder block lapho i-piston yelulelwe endaweni engaphandle kakhulu lapho i-valve. ivaliwe.
Ukufakwa komzimba we-cylinder kanye ne-valve nezindlela zokulungisa iphutha nezinyathelo zokuphepha:
Okokuqala faka i-valve esimweni esivaliwe ngamandla angaphandle, okungukuthi, vula i-valve shaft ngokwewashi kuze kube yilapho ipuleti le-valve selixhumene nesihlalo se-valve, futhi ngesikhathi esifanayo ubeke isilinda esimweni esivaliwe (okungukuthi, i-valve encane ngaphezu kwe-cylinder shaft I-groove i-perpendicular to the cylinder body (i-valve ezungeza iwashi ukuze ivale i-valve), bese ifaka isilinda ku-valve (indlela yokufaka ingahambisana noma i-perpendicular nomzimba we-valve), bese uhlola ukuthi izimbobo zesikulufa ziqondaniswe yini Ukuphambuka okukhulu, uma kukhona ukuphambuka okuncane, vele ujike i-cylinder block kancane, bese uqinisa izikulufa ze-valve ye-butterfly kuqala hlola ukuthi izesekeli ze-valve zifakwe ngokuphelele, i-solenoid valve kanye ne-muffler, njll., uma ingaqediwe, musa ukulungisa iphutha, umfutho womoya ohlinzeka ngokujwayelekile ngu-0.6MPA±I-0.05MPA, ngaphambi kokusebenza, qiniseka ukuthi ayikho imfucumfucu enamathele epuleti le-valve emzimbeni we-valve Ekuqaleni kokugunyazwa nokusebenza, sebenzisa inkinobho yokusebenza ngesandla ye-valve ye-solenoid (ikhoyili ye-solenoid ivaliwe ngesikhathi sokusebenza ngesandla, futhi ukusebenza okwenziwa ngesandla kuvumelekile lapho ukusebenza kokulawula ugesi kwenziwa, i-twist manual isethelwe ku-0 futhi ikhoyili ivaliwe, futhi ukusebenza okwenziwa ngesandla kuvumelekile; okungukuthi, i-valve ivuliwe lapho amandla evuliwe, futhi i-valve ivaliwe lapho amandla evaliwe.
Uma kutholakala ukuthi umenzi we-valve butterfly we-pneumatic uhamba kancane kakhulu endaweni yokuqala yokuvula i-valve ngesikhathi sokuthunywa nokusebenza, kodwa uyashesha kakhulu ngokushesha nje lapho ehamba.Ngokushesha, kulokhu, i-valve ivalwe ngokuqinile kakhulu, vele ulungise ukushaywa kwesilinda kancane (lungisa izikrini zokulungisa i-stroke kuzo zombili iziphetho zesilinda kancane ngesikhathi esifanayo, lapho ulungisa, i-valve kufanele ihanjiswe. endaweni evulekile, bese umthombo womoya kufanele uvaliwe Uvale bese ulungisa), lungisa kuze kube lula ukuvula nokuvala endaweni ngaphandle kokuvuza.Uma i-muffler iguquguquka, isivinini sokushintsha se-valve singashintshwa.Kuyadingeka ukulungisa i-muffler ekuvuleni okufanele kwejubane lokushintsha i-valve.Uma ukulungiswa kukuncane kakhulu, i-valve ingase ingasebenzi.
