Ivalvu yebhabhathane elinomoyaYakhiwe yi-actuator yomoya kanye ne-valve yebhabhathane. I-valve yebhabhathane yomoya isebenzisa ipuleti lebhabhathane eliyindilinga elijikeleza nesiqu se-valve ukuze livuleke futhi livale, ukuze kufezwe isenzo sokusebenza. I-valve yebhabhathane yomoya isetshenziswa kakhulu njenge-valve yokuvala, futhi ingaklanywa futhi ukuba nomsebenzi wokulungisa noma i-valve yesigaba kanye nokulungisa. Njengamanje, i-valve yebhabhathane isetshenziswa ngokucindezela okuphansi kanye nobukhulu. Isetshenziswa kakhulu kumapayipi ane-medium-bore.
Umgomo wokusebenza weivalvu yebhabhathane elinomoya
Ipuleti le-butterfly le-valve ye-butterfly lifakwe ohlangothini lobubanzi bepayipi. Emseleni oyisilinda womzimba we-valve ye-butterfly, ipuleti le-butterfly eliyi-disc lijikeleza i-axis, kanti i-engeli yokujikeleza iphakathi kuka-0°-90°Uma ukujikeleza kufinyelela ku-90°, ivalvu isesimweni sokuvuleka ngokuphelele. Ivalvu yevemvane ilula ngesakhiwo, incane ngosayizi futhi ilula ngesisindo, futhi inezingxenye ezimbalwa kuphela. Ngaphezu kwalokho, ingavulwa futhi ivalwe ngokushesha ngokujikeleza ama-90 kuphela.°, futhi ukusebenza kulula. Ngesikhathi esifanayo, ivalvu inezici ezinhle zokulawula uketshezi. Uma ivalvu yevemvane isendaweni evulekile ngokuphelele, ubukhulu bepuleti yevemvane yikona kuphela ukumelana lapho i-medium igeleza emzimbeni wevalvu, ngakho-ke ukwehla kwengcindezi okubangelwa yivalvu kuncane kakhulu, ngakho-ke kunezici ezinhle zokulawula ukugeleza. Amavalvu evemvane anezinhlobo ezimbili zokuvala: uphawu olunwebekayo kanye nophawu lwensimbi. Kumavalvu okuvala olunwebekayo, indandatho yokuvala ingafakwa emzimbeni wevalvu noma inamathiselwe emngceleni wepuleti yevemvane.
I-valve yebhabhathane yomoyaukulungiswa nokulungiswa kwamaphutha
1. Uhlelo lokuhlola nokulungisa isilinda
Ngokuvamile yenza umsebenzi omuhle wokuhlanza ubuso besilinda bese ugcoba ungqimba lwesilinda nge-oyili. Vula isembozo sokugcina sesilinda njalo njalo ezinyangeni ezi-6 ukuze uhlole ukuthi kukhona yini ukoma nomswakama kusilinda, kanye nesimo samafutha. Uma amafutha okugcoba engekho noma omile, kubalulekile ukuqaqa isilinda ukuze kulungiswe kahle futhi kuhlanzwe ngaphambi kokufaka amafutha okugcoba.
2. Ukuhlolwa komzimba we-valve
Njalo ezinyangeni ezi-6, hlola ukuthi umzimba we-valve ubukeka kahle yini, ukuthi kukhona yini ukuvuza eflangeni lokufaka, uma kulula, hlola ukuthi uphawu lomzimba we-valve luhle yini, alugugile yini, ukuthi ipuleti le-valve liyaguquguquka yini, nokuthi kukhona yini okunye okubambeke ku-valve.
Izindlela zokuhlukanisa amabhlogo esilinda kanye nokuhlanganisa kanye nezinyathelo zokuphepha:
Okokuqala susa isilinda emzimbeni wevalvu, qala ususe isembozo kuzo zombili izinhlangothi zesilinda, naka indlela i-piston rack eqondiswa ngayo lapho ususa i-piston, bese usebenzisa amandla angaphandle ukuzungeza i-cylinder shaft ngokwewashi ukuze wenze i-piston igijime iye ohlangothini olungaphandle, bese uvala i-valve. Imbobo ingena umoya kancane futhi i-piston iphushelwa ngaphandle kancane ngomfutho womoya, kodwa le ndlela kumele inake ukungenisa umoya kancane, ngaphandle kwalokho i-piston izophuma ngokuzumayo, okuyingozi kancane! Bese ususa i-circlip ku-cylinder shaft, bese i-cylinder shaft ingavulwa komunye umkhawulo. Yikhiphe. Ngemuva kwalokho ungahlanza ingxenye ngayinye bese ufaka amafutha. Izingxenye ezidinga ukugcoba yilezi: udonga lwangaphakathi lwesilinda kanye ne-piston seal ring, i-rack kanye ne-back ring, kanye ne-gear shaft kanye ne-seal ring. Ngemva kokugcoba amafutha, kumele ifakwe ngokwe-oda lokudiliza kanye ne-reverse order yezingxenye. Ngemuva kwalokho, kumele ifakwe ngokwe-oda lokudiliza kanye ne-reverse order yezingxenye. Naka indawo yegiya kanye ne-rack, futhi uqinisekise ukuthi i-piston iyancipha ifinyelele endaweni lapho i-valve ivuliwe. I-groove engxenyeni engenhla ye-gear shaft ihambisana ne-cylinder block ngesikhathi sokuma okungaphakathi, kanti i-groove engxenyeni engenhla ye-gear shaft iqonde ngqo ku-cylinder block lapho i-piston inwetshwa iye endaweni engaphandle lapho i-valve ivaliwe.
Izindlela zokufaka nokulungisa amaphutha kanye nezinyathelo zokuphepha:
Okokuqala faka ivalvu esimweni sokuvalwa ngamandla angaphandle, okungukuthi, phendula umshafti wevalvu ngokwewashi kuze kube yilapho ipuleti levalvu lixhumene nesihlalo sevalvu, bese ngesikhathi esifanayo faka isilinda esimweni sokuvalwa (okungukuthi, ivalvu encane ngaphezu komshafti wesilinda. Umsele uqonde ngqo emzimbeni wesilinda (wevalvu ejikeleza ngokwewashi ukuze ivale ivalvu), bese ufaka isilinda kuvalvu (isiqondiso sokufakwa singahambisana noma siqonde ngqo emzimbeni wevalvu), bese uhlola ukuthi izimbobo zezikulufo ziqondile yini. Ukuphambuka okukhulu, uma kukhona ukuphambuka okuncane, vele uphendule ibhlogo lesilinda kancane, bese uqinisa izikulufu. Ukulungisa iphutha levalvu yebhabhathane yomoya kuqala hlola ukuthi izesekeli zevalvu zifakiwe ngokuphelele, ivalvu ye-solenoid kanye ne-muffler, njll., uma kungaqediwe, ungalungisi, umfutho womoya ojwayelekile wokunikezwa ngu-0.6MPA±0.05MPA, ngaphambi kokusebenza, qiniseka ukuthi akukho mfucumfucu ebhajwe epuletini levalvu emzimbeni wevalvu. Ekuqalisweni kokuqala kokusebenza, sebenzisa inkinobho yokusebenza ngesandla yevalvu yesolenoid (ikhoyili yevalvu yesolenoid ivuliwe ngesikhathi sokusebenza ngesandla, futhi ukusebenza ngesandla kuyasebenza; lapho kwenziwa umsebenzi wokulawula kagesi, ukujika ngesandla kusethwe ku-0 futhi ikhoyili ivuliwe, futhi ukusebenza ngesandla kuyasebenza; isikhundla esingu-0 ukuvala ivalvu, 1 ukuvula ivalvu, okungukuthi, ivalvu ivuliwe lapho ugesi uvuliwe, futhi ivalvu ivaliwe lapho ugesi uvaliwe. isimo.
Uma kutholakala ukuthi umenzi we-valve ye-butterfly ephefumulayo uhamba kancane kakhulu endaweni yokuqala yokuvulwa kwe-valve ngesikhathi sokusebenza nokusebenza, kodwa kushesha kakhulu ngokushesha nje lapho ihamba. Ngokushesha, kulokhu, i-valve ivaliwe kakhulu, vele ulungise ukushaywa kwesilinda kancane (lungisa izikulufo zokulungisa ukushaywa kancane kuzo zombili iziphetho zesilinda ngesikhathi esisodwa, lapho ulungisa, i-valve kufanele ithuthelwe endaweni evulekile, bese umthombo womoya kufanele ucinywe. Yicime bese ulungisa), lungisa kuze kube yilapho i-valve kulula ukuyivula nokuyivala endaweni yayo ngaphandle kokuvuza. Uma i-muffler ilungiseka, isivinini sokushintsha se-valve singalungiswa. Kuyadingeka ukulungisa i-muffler ekuvulekeni okufanele kwesivinini sokushintsha i-valve. Uma ukulungiswa kuncane kakhulu, i-valve ingase ingasebenzi.
