I-Actuator Valve yivalvu ene-actuator edibeneyo, enokulawula ivalvu ngokusebenzisa imiqondiso yombane, imiqondiso yoxinzelelo lomoya, njl. Iquka umzimba wevalvu, idiski yevalvu, isiqu sevalvu, i-actuator, isalathisi sendawo kunye nezinye izinto.
I-actuator yinxalenye ebaluleke kakhulu ye-actuator. Ngaphambi kokuba siqonde i-actuator valve, kufuneka sazi i-actuator kuqala.
Yintoni i-Actuator
Inkcazo ye-Actuator
I-Actuator yinxalenye ebalulekileyo yezixhobo zobuchwepheshe bokulawula okuzenzakalelayo. Oku kulandelayo yinkcazo eneenkcukacha ngee-actuators.
Luhlobo luni lwee-Actuators
Ii-actuators zinokwahlulwa zibe ziindidi ezintathu ngokwemo yazo yamandla: i-pneumatic, i-hydraulic, kunye ne-electric.
I-Actuator yoMbane
I-actuator yombane ine-motor kunye nendlela yokuguqula ngaphakathi. I-motor iguqula intshukumo ejikelezayo ibe yintshukumo ethe tye ngokudluliselwa kwegiya, ityhala isiqu sevalvu phezulu nasezantsi, ngaloo ndlela ilawula inqanaba lokuvula kunye nesantya sokuhamba kwevalvu.
Ii-actuator zombane zinezibonelelo zesakhiwo esincinci, ukusebenza okulula, ukuchaneka kolawulo oluphezulu, kwaye kulula ukuzidibanisa neenkqubo zolawulo lwekhompyutha ukuze kufezekiswe ulawulo olukude kunye nolawulo oluzenzekelayo.
Ii-Actuators ze-Pneumatic
Ii-actuators ze-pneumatic lolunye uhlobo oluqhelekileyo lwee-actuators ezamkela imiqondiso ye-pneumatic kwaye ziyiguqulele kwintshukumo yoomatshini.
Ii-actuators ze-pneumatic zisetyenziswa kakhulu kwiivalvu zolawulo lwe-pneumatic kwimveliso yemizi-mveliso. Zamkela imiqondiso yolawulo ye-20 \ ~ 100kPa kwaye ziqhuba iivalvu ukuze zivule, zivalwe okanye zilungiswe. Ii-actuators ze-pneumatic zinezibonelelo zesantya sokuphendula ngokukhawuleza, ukuthembeka okuphezulu kunye nokugcinwa okulula. Zifanelekile ngokukodwa kwiimeko ezifuna impendulo ekhawulezileyo kunye nolawulo oluzinzileyo.
Ii-Hydraulic Actuators
Ii-hydraulic actuators zidlulisela amandla ngenkqubo ye-hydraulic. Isitishi se-hydraulic sinikeza ioyile yoxinzelelo, edluliselwa kwi-actuator ngepayipi yeoyile ukuze iqhube ivalvu okanye ezinye izixhobo zoomatshini. Ii-hydraulic actuators zihlala zixhotyiswe ngee-electro-hydraulic servo valves, ezinokufikelela kulawulo oluchanekileyo lwendawo kunye nolawulo lwamandla.
Ii-hydraulic actuators zifanelekile kwiimeko ezifuna i-thrust enkulu okanye i-torque, njengolawulo lweevalvu ezinkulu, ukuqhuba oomatshini abanzima kunye nezixhobo, njl. Ngenxa ye-thrust enkulu kunye nozinzo oluphezulu, ii-hydraulic actuators zihlala zisetyenziswa kwizicelo zoshishino ezifuna ukuthembeka okuphezulu kunye ne-thrust ephezulu.
Emva kokuba sifunde ulwazi lwee-actuator, makhe sifunde ngolwazi olufanelekileyo lwee-actuator valves.
Inkcazo kunye nomsebenzi weeValve zeActuator
Ivalvu ye-actuator ilungisa ngokuzenzekelayo imeko yokuvulwa nokuvalwa kwevalvu ngokufumana imiqondiso yolawulo lwangaphandle, ngaloo ndlela ifezekisa ulawulo oluchanekileyo lweeparameter ezifana nokuhamba, uxinzelelo, kunye nobushushu. Isetyenziswa kakhulu kwiinkqubo zolawulo lwe-automation yemizi-mveliso ukuphucula ukusebenza kakuhle kwemveliso kunye nokhuseleko lwemveliso.
Iivalvu ze-Actuator zingahlulwahlulwa zibe ziindidi ezintathu ngokweendlela ezahlukeneyo zokuqhuba: iivalvu ze-actuator ze-pneumatic, iivalvu ze-hydraulic actuator, kunyeiivalvu ze-actuator zombane.
Iivalvu ze-Actuator ze-Pneumatic
Iivalvu ze-pneumatic actuator ziivalvu eziqhutywa zii-actuators ze-pneumatic. Zizixhobo eziqhuba ukuvula nokuvala iivalvu ze-pneumatic series angle-stroke ezifana neIivalvu zeBhola zoMoya, Iivalvu zeButterfly zePneumatic, Iivalvu zeSango lePneumatic, Iivalvu zeGlobe yePneumatic, iivalvu ze-diaphragm ze-pneumatic, kunye neevalvu ezilawula i-pneumatic. Zizixhobo ezifanelekileyo zokulawula imibhobho ye-automation yemizi-mveliso ekude okanye yomntu ngamnye.
Iivalvu ze-Actuator zoMbane
Iivalvu ze-actuator zombane ziivalvu eziqhutywa zii-actuator zombane. Zahlulwe zibe ziintlobo ze-multi-turn, i-partial-turn, i-straight-through, kunye ne-angle-through.
Ii-actuators ezijika-jika ezininzi: isetyenziselwa iivalvu zesango, iivalvu zokumisa, kunye nezinye iivalvu ezifuna ukujikeleza okuninzi kwesiphatho ukuze zivuleke kwaye zivale, okanye ziqhube iivalvu zebhabhathane, iivalvu zebhola, iivalvu zeplagi, kunye nezinye iivalvu ezijika kancinci ngokusebenzisa iidrives zegiya zeworm.
Isixhobo sokujika esingaphelelanga: isetyenziselwa iivalvu zebhabhathane, iivalvu zebhola, iivalvu zeplagi, njl.njl., ezinokuvulwa zize zivalwe ngokujikeleza ii-degrees ezingama-90
I-actuator ethe ngqo: isetyenziselwa iivalvu ezine-actuator drive shaft kunye ne-valve stem ezikwicala elinye
Isixhobo sokusebenza nge-engile: isetyenziselwa iivalvu ezine-actuator drive shaft kunye ne-valve stem ezime nkqo
Iivalvu zeHydraulic Actuator
Iivalvu ze-hydraulic actuator sisixhobo sokuqhuba ivalvu esisebenzisa i-hydraulic transmission njengamandla. Uphawu lwayo oluphawulekayo kukutyhala okukhulu, kodwa inkulu kwaye ifanelekile kwiimeko ezithile ezifuna ukutyhala okukhulu.
Iivalvu zoLawulo
Iivalvu ze-actuator ze-pneumatic, iivalvu ze-Hydraulic actuator, kunye neevalvu ze-Electric actuator zonke ziivalvu zoLawulo. Iivalvu zoLawulo zingahlulwahlulwa zibeI-SDV (iivalvu zeShutdonw)kunye neeValvu eziLawula.
