Isimiso sokusebenza sedivayisi kagesi ye-valve

Isimiso sokusebenza sedivayisi kagesi ye-valve Ngenxa yokuthi uhlobo lwe-valve luyi-multifarious, ukuze lwakhiwe futhi lusetshenziswe kalula, umbuso wenze izinhlinzeko ezifanayo endleleni yokuhlanganisa imodeli yomkhiqizo we-valve. Inombolo yemodeli yomkhiqizo wevalvu iqukethe amayunithi ayisikhombisa akhombisa uhlobo lwevalvu, uhlobo lwedrayivu, ijoyinti nokwakhiwa, okokuvala noma ulayini, ukucindezela okulinganiselwe kanye nempahla yomzimba. Uhlobo lwe-valve lusetshenziselwa ukumela uhlobo lwe-valve, ifomu lokushayela nokuxhuma, impahla yendandatho yokuvala kanye nokucindezela okuzisholo nezinye izakhi. Ukwakheka kohlobo lwevalvu kuqukethe amayunithi ayisikhombisa ngokulandelana... Uhlobo lwevalvu Uhlobo lwevalvu lusetshenziselwa ukumela uhlobo lwevalvu, uhlobo lokushayela kanye nokuxhuma, indandatho yokuvala kanye nokucindezela okulinganiselwe nezinye izakhi. Ngenxa yokuthi uhlobo lwe-valve lunezinhlobonhlobo eziningi, ukuze lukhiqize futhi lusetshenziswe kalula, umbuso wenze izinhlinzeko ezifanayo endleleni yokuhlanganisa imodeli yomkhiqizo we-valve. Inombolo yemodeli yomkhiqizo wevalvu iqukethe amayunithi ayisikhombisa akhombisa uhlobo lwevalvu, uhlobo lwedrayivu, ijoyinti nokwakhiwa, okokuvala noma ulayini, ukucindezela okulinganiselwe kanye nempahla yomzimba. Ukwakheka kohlobo lwevalvu kuqukethe amayunithi ayisikhombisa ngokulandelana (bheka ithebula elingezansi) 1. Uhlobo lwekhodi yevalvu 2. Ikhodi yemodi yokudlulisela ivezwe ngezinombolo zesi-Arabhu ngokwethebula 1-2 Ithebula 1-2 Qaphela: ① Isondo lesandla , isibambo kanye ne-wrench drive kanye ne-valve yokuphepha, i-valve yokunciphisa ingcindezi, i-trap ikhishwe le khodi. ② Nge-pneumatic noma i-hydraulic: ngokuvamile ivula nge-6K, 7K; Ngokuvamile kuvalwe ngo-6B, 7B; Isandla somoya esine-6S sathi. Ukusebenza kukagesi okungaqhumi "9B". 3. Amakhodi efomu lokuxhuma amelwe ngezinombolo zesi-Arabhu njengoba kushiwo kuThebula 1-3 Ithebula 1-3 Qaphela: Ukushisela kuhlanganisa ukushisela izinqe kanye nokushisela isokhethi 4. Umshini kagesi wevalvu uwukubona isilawuli sohlelo lwe-valve, isilawuli esizenzakalelayo nesilawulikude esibalulekile. imishini yokushayela, inqubo yayo yokunyakaza ingalawulwa ngokushaywa unhlangothi, i-torque noma usayizi we-axial thrust. Ngoba izici zokusebenza kwedivayisi kagesi ye-valve kanye nokusetshenziswa kuncike ohlotsheni lwe-valve, imininingwane esebenzayo yedivayisi kanye nendawo ye-valve epayipini noma impahla. Idivayisi kagesi ngokuvamile iqukethe lezi zingxenye ezilandelayo: I-Motor ibonakala ngomthamo oqinile wokugcwala, i-torque enkulu yokuqala, isikhashana esincane se-inertia, isikhathi esifushane, umsebenzi wesikhashana. Indlela yokunciphisa yokunciphisa isivinini sokuphuma kwemoto. Indlela yokulawula i-stroke ukulungisa nokulawula ngokunembile indawo yokuvula nokuvala ye-valve. Indlela yokukhawulela i-torque yokulungisa i-torque (noma i-thrust) ibe inani elinqunywe kusengaphambili. Umshini wokushintsha owenziwe ngesandla nokagesi, umshini wokuxhumanisa wokusebenza okwenziwa ngesandla noma kagesi. Inkomba yokuvula ibonisa isikhundla se-valve ngesikhathi sokuvula nokuvala. Okokuqala, khetha i-actuator kagesi ngokohlobo lwe-valve 1. I-Angle stroke actuator kagesi (ikhona 360 degrees) ifanele i-valve uvemvane, i-valve yebhola, i-plug valve, njll. Ngesonto, okungukuthi, ngaphansi kwama-degree angu-360, ngokuvamile ama-degree angu-90 ukuze abone ukulawulwa kwenqubo yokuvula nokuvala i-valve. Lolu hlobo lwe-actuator kagesi luhlukaniswe ngohlobo lokuxhuma oluqondile kanye nohlobo lwe-crank eyisisekelo ngokuya ngemodi yokufaka ehlukile yokufaka. A) Okuxhunywe ngokuqondile: kubhekisela ohlotsheni lokufakwa okuxhunywe ngokuqondile kwe-shaft ephumayo ye-actuator kagesi kanye nesiqu se-valve. B) Uhlobo lwe-Base crank: lubhekisela esimweni lapho i-shaft ephumayo ixhunywe khona nesiqu se-valve ngokusebenzisa i-crank. 2. I-Multi-rotary actuator kagesi (ikhoneni elingu-360 degrees) ilungele ama-valve esango, ama-valve embulunga, njll. Ukujikeleza kwe-shaft okukhiphayo ye-actuator kagesi kukhulu kunesonto elilodwa, okungukuthi, kukhulu kunama-degree angu-360. Ngokuvamile idinga umbuthano ongaphezu kwesisodwa ukuze ibone ukulawulwa kwenqubo yokuvula nokuvala kwe-valve. 3. I-stroke eqondile (ukunyakaza okuqondile) ifanele i-valve yokulawula isihlalo esisodwa, i-valve yokulawula izihlalo ezimbili, njll. Ukunyakaza kwe-shaft ephumayo ye-actuator kagesi ukunyakaza okuqondile, hhayi ukujikeleza. Okwesibili, ngokwezidingo zokulawula inqubo yokukhiqiza ukuze kunqunywe imodi yokulawula ye-actuator kagesi 1. Ukushintsha uhlobo (ukulawula iluphu evulekile) Ukushintsha uhlobo lwe-actuator kagesi ngokuvamile kuqonda ukulawula noma ukuvala i-valve. I-valve isendaweni evuleke ngokugcwele noma isendaweni evalwe ngokugcwele. Lolu hlobo lwe-valve aludingi ukulawula ngokunembile ukugeleza okuphakathi. Kuhle kakhulu ukusho ukuthi ukushintsha ama-actuator kagesi nakho kungahlukaniswa ngesakhiwo esihlukanisayo kanye nesakhiwo esihlanganisiwe ngenxa yezinhlobo ezahlukene zesakhiwo. Lokhu kufanele kuchazwe lapho kukhethwa uhlobo, ngaphandle kwalokho kuvame ukwenzeka ohlelweni lokufakwa nokulawula kwensimu *** nokunye ukungafani. A) Isakhiwo sokuhlukanisa (ngokuvamile esibizwa ngokuthi uhlobo oluvamile) : iyunithi yokulawula ihlukaniswa ne-actuator kagesi. I-actuator kagesi ayikwazi ukulawula i-valve ngokuzimela, kodwa kufanele ilawulwe yiyunithi yokulawula yangaphandle. Ngokuvamile, isilawuli sangaphandle noma ikhabhinethi yokulawula isetshenziselwa ukusekela. Ububi balesi sakhiwo ukuthi akulula ukufakwa okuphelele kwesistimu, ukwandisa izindleko zezintambo nokufaka, futhi kujwayele ukwehluleka, lapho ukwehluleka kwenzeka, akulula ukuxilongwa nokugcinwa, ukonga imali akulungile. . B) Isakhiwo esihlanganisiwe (esivame ukubizwa ngokuthi uhlobo olubalulekile) : iyunithi yokulawula kanye ne-actuator kagesi zipakishwa zizonke, ezingasetshenzwa endaweni ngaphandle kweyunithi yokulawula yangaphandle, futhi ingaqhutshwa ukude kuphela ngokukhipha ulwazi lokulawula olufanele. Izinzuzo zalesi sakhiwo ukufakwa kwesistimu yonke elula, ukunciphisa izindleko zezintambo nokufaka, ukuxilongwa okulula nokuxazulula izinkinga. Kodwa-ke, imikhiqizo yesakhiwo esihlanganisiwe yendabuko nayo inokungapheleli okuningi, ngakho-ke i-actuator kagesi ehlakaniphile ikhiqizwa. 2. Uhlobo lokulawula (ukulawula i-loop evaliwe) olulawula uhlobo lwe-actuator kagesi alunayo nje umsebenzi wokushintsha uhlobo oluhlanganisiwe lwesakhiwo, kodwa futhi lungalawula ngokunembile i-valve futhi lulungise ukugeleza okuphakathi. A) Uhlobo lwesiginali yokulawula (yamanje ne-voltage) Isignali yokulawula ye-actuator kagesi ngokuvamile inesignali yamanje (4 ~ 20MA, 0 ~ 10MA) noma isignali ye-voltage (0 ~ 5V, 1 ~ 5V). Uhlobo namapharamitha wesignali yokulawula kufanele kucace lapho kukhethwa uhlobo. B) Imodi yomsebenzi (ugesi uvuliwe, ucishiwe ugesi) olawula imodi yokusebenza ye-actuator kagesi ngokuvamile ivuliwe (thatha isilawuli esingu-4 ~ 20MA njengesibonelo, i-electric on ibhekisela kusignali ye-4MA ehambisana nokuvala i-valve, i-20MA ehambisana ne-valve evuliwe) , enye iwuhlobo lwe-electric off (thatha isilawuli se-4-20MA njengesibonelo, i-electric on ibhekisela kusignali ye-4MA ehambisana ne-valve evulekile, i-20MA ihambisana ne-valve off). C) Ukulahleka kokuvikela isignali Ukulahlekelwa ukuvikela kwesignali kubhekisela ekutheni lapho isignali yokulawula ilahleka ngenxa yamaphutha olayini, i-actuator kagesi izovula futhi ivale i-valve yokulawula enanini lokuvikela elimisiwe. Inani elijwayelekile lokuvikela livuleke ngokuphelele, livalwe ngokuphelele futhi lisendaweni. Ngokwezidingo zendawo yokusetshenziswa kanye nebanga lobufakazi bokuqhuma, idivayisi kagesi ye-valve ingahlukaniswa ngohlobo olujwayelekile, uhlobo lwangaphandle, uhlobo olungashi, uhlobo lwangaphandle olungashi, njll. Okune, ngokusho kwe-torque ye-valve edingekayo kuma-actuator kagesi. i-torque ephumayo yokuvula nokuvala i-torque edingekayo inquma i-torque ephumayo ye-actuator kagesi ukuze ikhethe ukuthi, ngokuvamile ibekwa kanjani phambili ngumsebenzisi noma ngumkhiqizi wamavalvu afanayo, njengoba umenzi we-actuator enesibopho kuphela nge-torque ephumayo yama-actuator, Ukuvulwa kwe-valve evamile nokuvala i-torque edingekayo kunqunywa usayizi wobubanzi be-valve, izici ezifana nokucindezela kokusebenza, Kodwa ngenxa yokunemba kokucubungula komkhiqizi we-valve, inqubo yokuhlanganisa, ukuze ukukhiqizwa komkhiqizi ohlukile we-torque efanayo edingekayo ye-valve nakho kuhluke. , ngisho nokucaciswa okufanayo nge-torque yomkhiqizi we-valve ye-valve kuhlukile futhi, ukukhetha kwetorque yohlobo lwe-actuator kuncane kakhulu kuzokwenza ukuthi i-valve ayikwazi ukuvula/ukuvala, i-actuator kagesi kufanele ikhethe uhla olufanele lwetorque. Okwesihlanu, ukukhethwa okulungile kwedivayisi kagesi ye-valve esekelwe: i-torque yokusebenza: i-torque yokusebenza iyipharamitha eyinhloko yedivayisi kagesi ye-valve, i-torque ephumayo yedivayisi kagesi kufanele ibe izikhathi ezingu-1.2 kuya kwezingu-1.5 ze-torque yokusebenza kwe-valve. I-Operation thrust: kunezakhiwo ezimbili eziyinhloko zedivayisi kagesi ye-valve: eyodwa ayinayo i-thrust plate, i-torque ephumayo eqondile; Enye ifakwe i-thrust disc, i-torque ephumayo nge-thrust disc stem nut iguqulelwe ku-output thrust. Isibalo sendingilizi ye-valve yokuzungezisa: inombolo ye-laps valve actuator kagesi ephumayo ezungezayo enobubanzi obujwayelekile bevalvu, intambo ye-valve stem, intambo, ngokuya ngokubala kwe-M = H/ZS (M yamadivaysi kagesi kufanele anelise inani eliphelele indandatho ejikelezayo, H ubude be-valve evuleka, u-S we-stem drive screw pitch, u-Z wentambo ye-stem). Ububanzi be-stem: kuma-valve we-stem ohlobo oluningi, uma ububanzi be-stem obukhulu ngokuqhathaniswa obuvunyelwe idivayisi kagesi bungakwazi ukudlula isiqu se-valve ye-valve, ngeke buhlanganiswe ku-valve kagesi. Ngakho-ke, ububanzi bangaphakathi bomgodi wokuphuma ongenalutho wedivayisi kagesi kufanele bube bukhulu kunobubanzi obungaphandle besiqu se-valve ye-stem evulekile. Kwamanye ama-valve ajikelezayo kanye nama-valve amaningi ajikelezayo ku-valve yenduku emnyama, nakuba ungacabangi ububanzi be-stem ngenkinga, kodwa ekukhetheni kufanele futhi kubhekwe ngokugcwele ububanzi be-stem kanye nobukhulu bokhiye, ukuze umhlangano usebenze ngokujwayelekile. Ijubane lokukhiphayo: uma isivinini sokuvula nokuvala sishesha kakhulu, kulula ukukhiqiza umkhuba wokushaywa kwamanzi. Ngakho-ke, isivinini esifanelekile sokuvula nokuvala kufanele sikhethwe ngokuvumelana nezimo ezihlukene zokusebenza.
