Umatshini wokutshintsha okwenziwa ngesandla kunye nombane, indlela yokudityaniswa kwesixhobo sokusebenza ngesandla okanye sombane. Isalathisi sokuvula sibonisa indawo yevalve ngexesha lokuvula nokuvala. Okokuqala, khetha i-actuator yombane ngokohlobo lwe-valve 1. I-Angle stroke actuator yombane (ikona ye-360 degrees) ifanelekile kwivalve yebhabhathane, ivalve yebhola, ivalve yeplagi, njl njl. ngeveki, oko kukuthi, ngaphantsi kwe-360 degrees, ngokuqhelekileyo i-90 degrees ukuqonda ukuvulwa kwevalve kunye nokulawula inkqubo yokuvala. Olu hlobo lwe-actuator yombane lwahlulwe lwaba ludidi loqhagamshelo oluthe ngqo kunye nohlobo lwesiseko secrank ngokwendlela yojongano lofakelo olwahlukileyo. A) Iqhagamshelwe ngokuthe ngqo: ibhekisa kuhlobo lofakelo oludityanisiweyo ngokuthe ngqo lweshafti ephumayo ye-actuator yombane kunye nesiqu sevalve. B) Uhlobo lwe-Base crank: ibhekisa kuhlobo apho i-shaft ephumayo idityaniswe nesiqu sevalvu ngekranki. 2. I-multi-rotary actuator yombane (ikona ye-360 degrees) ifanelekile kwiivalve zesango, i-globe valves, njl. Ngokuqhelekileyo idinga ngaphezulu kwesangqa esinye ukuqonda inkqubo yokuvula nokuvala inkqubo yevalve. 3. I-stroke echanekileyo (intshukumo echanekileyo) ifanelekile kwi-valve yokulawula isihlalo esinye, i-valve yokulawula isihlalo ezimbini, njl. Ezimbini, ngokweemfuno zolawulo lwenkqubo yokuvelisa ukumisela indlela yokulawula i-actuator yombane 1. Uhlobo lokutshintsha (ulawulo oluvulekileyo lwe-loop) Ukutshintsha uhlobo lwe-actuator yombane ngokubanzi luqonda ukulawulwa okanye ukuvala ivalve. Ivalve ikwimo evuleke ngokupheleleyo okanye ikwindawo evalwe ngokupheleleyo. Olu hlobo lwesivalo aludingi ukulawula ngokuchanekileyo ukuhamba okuphakathi. Kubaluleke kakhulu ukukhankanya ukuba ukutshintsha i-actuator zombane nako kunokwahlulahlula kwisakhiwo esahlukileyo kunye nesakhiwo esidibeneyo ngenxa yeefom ezahlukeneyo zesakhiwo. Oku kufuneka kucaciswe xa ukhetha uhlobo, kungenjalo kudla ukwenzeka kwintsimi yofakelo kunye nesixokelelwano solawulo *** kunye nokunye ukungalingani. A) Isakhiwo sokwahlula (ngokuqhelekileyo sibizwa ngokuba luhlobo oluqhelekileyo) : iyunithi yokulawula ihlukaniswe kwi-actuator yombane. I-actuator yombane ayikwazi ukulawula i-valve ngokuzimeleyo, kodwa kufuneka ilawulwe yiyunithi yokulawula yangaphandle. Ngokuqhelekileyo, umlawuli wangaphandle okanye ikhabhinethi yokulawula isetyenziselwa ukuxhasa. Ukungalungi kwesi sakhiwo kukuba ayilungele ukufakwa ngokubanzi kwenkqubo, ukunyuka kweengcingo kunye neendleko zokufakela, kunye nokuthanda ukusilela, xa ukusilela kusenzeka, ayilungele ukuxilongwa kunye nokugcinwa kwayo, indleko-esebenzayo ayifanelekanga. . B) Isakhiwo esidibeneyo (esiqhelekileyo sibizwa ngokuba luhlobo oludibeneyo) : iyunithi yokulawula kunye ne-actuator yombane zipakishwe ngokupheleleyo, ezinokuthi ziqhutywe kwindawo ngaphandle kweyunithi yokulawula yangaphandle, kwaye inokusebenza ngokude kuphela ngokukhupha ulwazi olufanelekileyo lolawulo. Iingenelo zesi sakhiwo yinkqubo efanelekileyo yokufakela ngokubanzi, ukunciphisa i-wiring kunye neendleko zokufakela, ukuxilongwa lula kunye nokuxazulula iingxaki. Nangona kunjalo, iimveliso zendalo ezidityanisiweyo zesakhiwo nazo zineziphene ezininzi, ngoko ke i-activator yombane ekrelekrele iveliswa. 2. Uhlobo lokulawula (ulawulo oluvaliweyo) olulawula uhlobo lwe-actuator yombane alunayo nje umsebenzi wokutshintsha uhlobo oludibeneyo lwesakhiwo, kodwa lunokulawula ngokuchanekileyo i-valve kunye nokulungelelanisa ukuhamba okuphakathi. A) Uhlobo lophawu lolawulo (olwangoku kunye nombane) Umqondiso wolawulo wolawulo lwe-actuator yombane ngokubanzi unomqondiso wangoku (4 ~ 20MA, 0 ~ 10MA) okanye umqondiso wombane (0 ~ 5V, 1 ~ 5V). Uhlobo kunye neeparamitha zesignali yokulawula kufuneka zicace xa ukhetha uhlobo. B) indlela yokusebenza (umbane uvuliwe, ucinywe umbane) ulawula imowudi yokusebenza ye-actuator yombane ngokubanzi kumbane (thatha i-4 ~ 20MA ulawulo njengomzekelo, umbane osebenzayo ubhekisela kumqondiso we-4MA ohambelana nokuvala ivalve, i-20MA ehambelana ne-valve evulekileyo) , enye i-electric off type (thatha i-4-20MA yokulawula njengomzekelo, umbane ubhekiselele kwisignali ye-4MA ehambelana ne-valve evulekileyo, i-20MA ihambelana ne-valve off). C) Ilahleko yokukhuselwa komqondiso Ukulahleka kokukhusela umqondiso kubhekisela ekubeni xa umqondiso wokulawula ulahlekile ngenxa yeempazamo zomgca, i-actuator yombane iya kuvula kwaye ivale i-valve yokulawula kwixabiso lokukhusela elibekiwe. Ixabiso eliqhelekileyo lokukhusela livuleke ngokupheleleyo, livalwe ngokupheleleyo kwaye likwi-situ. Ngokweemfuno zendawo yokusetyenziswa kunye nebakala lobungqina bokuqhuma, isixhobo sombane sevalve sinokwahlulwa sibe luhlobo oluqhelekileyo, uhlobo lwangaphandle, uhlobo lwe-flameproof, uhlobo lwangaphandle lwe-flameproof, njl. itorque yokuphuma kwevalve yokuvula kunye nokuvala itorque efunekayo imisela itorque ye-actuator yombane ukukhetha indlela, ngokubanzi ibekwe phambili ngumsebenzisi okanye ngokuthelekisa umenzi wevalvu, njengoko umenzi we-actuator enoxanduva kuphela lwetorque yemveliso ye-actuator, Ukuvulwa kwevalve eqhelekileyo kunye nokuvala i-torque efunekayo kumiselwa ngubungakanani bedayamitha yevalve, izinto ezinje ngoxinzelelo lokusebenza, Kodwa ngenxa yokuchaneka komenzi wevalve, inkqubo yokuhlanganisa, ukwenzela ukuba ukuveliswa komenzi wevalve efanayo efunekayo itorque ikwahlukile. , nkqu inkcazo efanayo kunye ne-valve yokuvelisa i-torque yevalve yahlukile kwakhona, ukhetho lwe-torque yohlobo lwe-actuator luncinci kakhulu luya kubangela ukuba awukwazi ukuvula / ukuvala ivalve, i-actuator yombane kufuneka ikhethe uluhlu olufanelekileyo lwetorque. Isihlanu, ukhetho oluchanekileyo lwesixhobo sombane sevalve esekelwe: i-torque yokusebenza: i-torque yokusebenza yeyona parameter yesixhobo sombane sevalve, i-torque ephumayo yesixhobo sombane kufuneka ibe ngamaxesha angama-1.2 ukuya kwe-1.5 yetorque yokusebenza kwevalve. I-Operation thrust: kukho izinto ezimbini eziphambili zesixhobo sombane sevalve: enye ayixhotyiswanga ngepleyiti yokutyhala, itorque ephuma ngokuthe ngqo; Enye ixhotyiswe nge-thrust disc, i-torque yemveliso ngokusebenzisa i-thrust disc stem nut iguqulelwe kwi-output thrust. Ubalo lwesangqa sojikelezo lweshaft yesiphumo: inani lemijikelo yevalve yombane weactuator yokujikeleza kweshafti enedayamitha yegama levalve, isiqu sevalve somsonto wepitch, intambo, ngokweM = H/ZS ubalo (M yezixhobo zombane kufuneka yanelise inani elipheleleyo umsesane ojikelezayo, H bubude bevalve iyavula, S yestem drive screw pitch, Z yestem thread). Idayamitha ye-Stem: kwiivalve ze-stem zohlobo oluninzi, ukuba i-stem diameter enkulu evunyelwe sisixhobo sombane ayinakudlula isiqu sevalve yevalve, ayinakudityaniswa kwivalve yombane. Ngoko ke, i-diameter yangaphakathi ye-hollow output shaft yesixhobo sombane kufuneka ibe mkhulu kunobubanzi obungaphandle besiqu se-valve ye-stem evulekileyo. Kwezinye iivalve ezijikelezayo kunye neevalve ezininzi ezijikelezayo kwi-valve yentonga emnyama, nangona ungaqwalaseli ububanzi be-stem ngengxaki, kodwa ekukhetheni kufuneka kuqwalaselwe ngokupheleleyo ububanzi be-stem kunye nobukhulu be-keyway, ukuze indibano isebenze ngokuqhelekileyo. Isantya sokuphuma: ukuba i-valve yokuvula kunye nesantya sokuvala sikhawuleza kakhulu, kulula ukuvelisa into yokubetha kwamanzi. Ngoko ke, isantya esifanelekileyo sokuvula kunye nokuvala kufuneka sikhethwe ngokweemeko ezahlukeneyo zokusebenza.
