I-valve yevemvane yomoyayakhiwe 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, ukushuba 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, ukuthi ipuleti le-valve liyaguquguquka, nokuthi kukhona yini udaba lwangaphandle olunamathele ku-valve.
I-cylinder block disassembly nezindlela zokuhlanganisa nezindlela zokuphepha:
Okokuqala susa isilinda emzimbeni we-valve, qala ususe isembozo kuzo zombili iziphetho ze-cylinder, unake isiqondiso se-piston rack lapho ususa i-piston, bese usebenzisa amandla angaphandle ukuze ujikeleze i-cylinder shaft ngewashi ukuze wenze i-piston igijime ohlangothini olungaphandle, bese uvala i-valve Imbobo ifakwe umoya kancane futhi i-piston nge-air pressure kufanele ikhishwe kancane kancane, kodwa kancane kancane kufanele ikhiphe umoya kancane kancane, kodwa kancane kancane i-ventilate indlela. 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 engxenyeni engenhla ye-shaft yegiya 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 lapho i-valve ivaliwe.
Ukufakwa komzimba we-cylinder kanye ne-valve nezindlela zokulungisa iphutha nezinyathelo zokuphepha:
Okokuqala faka i-valve endaweni evaliwe ngamandla angaphandle, okungukuthi, vula i-valve shaft ngokwewashi kuze kube yilapho ipuleti le-valve lithintana nesihlalo se-valve, futhi ngesikhathi esifanayo ubeke isilinda endaweni evaliwe (okungukuthi, i-valve encane ngaphezu kwe-cylinder shaft I-groove i-perpendicular kumzimba we-cylinder (i-valve ezungeza i-valve ukuze ifake i-valve ngendlela yewashi) ihambisane noma i-perpendicular kumzimba we-valve), bese uhlola ukuthi izimbobo ze-screw ziqondaniswe yini, uma kukhona ukuphambuka okuncane, vele uvule i-cylinder block kancane, bese uqinisa izikulufa ze-valve ye-valve kuqala hlola ukuthi izesekeli ze-valve zifakwe ngokuphelele, i-solenoid valve kanye ne-muffler yomoya, njll.±I-0.05MPA, ngaphambi kokusebenza, qiniseka ukuthi ayikho imfucumfucu ebhajwe epuleti le-valve emzimbeni we-valve Ekuthumeni kokuqala nokusebenza, sebenzisa inkinobho yokusebenza ngesandla ye-valve ye-solenoid (ikhoyili ye-solenoid valve ivaliwe ngesikhathi sokusebenza ngesandla, nokusebenza ngesandla kusebenza; lapho ukusebenza kokulawula ugesi kwenziwa, i-twist manual isethwe ku-0 futhi i-oval ivaliwe; i-0 ivaliwe; i-valve, i-1 ukuvula i-valve, 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 emikhawulweni yomibili yesilinda kancane ngesikhathi esifanayo, lapho ulungisa, i-valve kufanele ihanjiswe endaweni evulekile, bese uvala umthombo womoya Uvale bese ulungisa), lungisa kuze kube lula ukuvula nokuvala i-valve endaweni ngaphandle kwe-lea. 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.
