Insiza eyinhloko ye-actuator yomoya yi-i-valve yokulawulaobeka indawo.Isebenza ngokuhambisana ne-actuator ye-pneumatic ukukhulisa i-ukunemba kokuma kwe-valve, nciphisa imiphumela yamandla okungalingani okuphakathi kanye nokungqubuzana kwesiqu, futhi uqiniseke ukuthi i-valve isabela kusignali yomlawuli.thola indawo efanele.

Lezi zimo ezilandelayo zenza kudingeke ukuthi kusetshenziswe indawo yokubuka indawo:
Lapho ukucindezela okuphakathi kuphezulu futhi kunomehluko omkhulu wengcindezi;2. Uma izinga levalvu elawulayo likhulu (DN>100);
3. Ivalvu elawula izinga lokushisa eliphezulu noma eliphansi;
4. Lapho kubalulekile ukusheshisa umsebenzi wevalvu elawulayo;
5. Uma amasiginali ajwayelekile asetshenziswa ukushayela ama-actuator ngobubanzi bentwasahlobo obungajwayelekile (ububanzi basentwasahlobo ngaphandle kuka-20-100KPa);
6. Noma nini lapho kusetshenziswa ukulawulwa kobubanzi bokuhlukanisa;
7. Uma i-valve iphendulwa, izikhombisi-ndlela zomoya-ukuvala kanye ne-air-to-open zishintshashintsha;
8. Lapho i-positioner cam idinga ukushintshwa ukuze kushintshwe izici zokugeleza kwevalvu;
9. Uma kufanele kufezwe isenzo esilinganiselwe, asikho isiqhumiseli se-piston noma indlela yokukhipha intwasahlobo;
10. Izibonisi zamavalvu zikagesi-womoya kufanele zisatshalaliswe lapho kusetshenziswa amasiginali kagesi ukulawula ama-actuator womoya.

I-valve ye-electromagnetic: I-valve ye-solenoid kufanele ifakwe ohlelweni lapho ukulawulwa kohlelo noma ukulawulwa kwezikhundla ezimbili kuyadingeka.Ukusebenzisana phakathi kwe-valve ye-solenoid kanye ne-valve elawulayo kufanele kucatshangelwe lapho kukhethwa i-solenoid valve ngaphezu komthombo wamandla we-AC ne-DC, i-voltage, kanye nemvamisa.Ingaba nomsebenzi "ovulekile ngokujwayelekile" noma "okuvalwe ngokujwayelekile".
Ama-valve amabili e-solenoid angasetshenziswa ngokuhambisana uma kudingekile ukwandisa umthamo we-solenoid valve ukuze kuncishiswe isikhathi sokusebenza, noma i-solenoid valve ingasetshenziswa njenge-valve yokushayela ngokuhambisana ne-relay yomoya yomthamo omkhulu.

I-pneumatic relay: I-pneumatic relay iwuhlobo lwesikhulisamandla samandla esingase sidlulisele isignali yomfutho womoya endaweni ekude ukuze kususwe ukuleleka okulethwe ukunwetshwa kwepayipi lesignali.Phakathi kwesilawuli kanye ne-valve elawula insimu, kunomsebenzi owengeziwe wokukhulisa noma ukunciphisa isignali.Isetshenziswa ngokuyinhloko phakathi kwe-transmitter yasensimini kanye nedivayisi yokulawula egumbini lokulawula elimaphakathi.

isiguquli:
I-converter ihlukaniswe yaba i-gas-electric converter kanye ne-electric-gas converter.Umsebenzi wayo ukuqaphela ukuguqulwa okufanayo kobudlelwane obuthile phakathi kwegesi kanye namasignali kagesi.Isetshenziswa kakhulu ukuguqula 0~10mA noma 4~ 20mA ukuguqulwa kwesignali kagesi noma 0 ~ 100KPa isignali yegesi ibe isignali kagesi engu-0 ~ 10mA noma 4 ~ 20mA.

isilawuli sezihlungi zomoya:

Okunamathiselwe kwedivayisi esetshenziswa nemishini yezimboni ezishintshayo yisihlungi somoya valvu yokwehlisa.Umsebenzi wawo oyinhloko uwukusimamisa ingcindezi ezingeni olifunayo ngenkathi ihlunga futhi ihlanza umoya ocindezelwe ophuma ku-compressor yomoya.Isilinda somoya, okokusebenza kokufafaza, imithombo yokuphakelwa komoya, nemishini yokusimamisa ingcindezi yamathuluzi amancane omoya ezinye zezibonelo zamathuluzi omoya namavalvu e-solenoid angasetshenziswa kuwo.

I-valve yokuphepha (i-valve yokuzikhiya)

I-valve yokuzikhiya iwumshini ogcina i-valve isendaweni.Uma umthombo womoya wehluleka, idivayisi ingacisha isignali yomthombo womoya ukuze igcine ikamelo le-membrane noma isignali yokucindezela yesilinda ezingeni layo langaphambi kokwehluleka kanye nendawo yevalvu endaweni yayo yangaphambi kokwehluleka.Emthelela wokuvikela isikhundla.

i-position transmitter yama-valve
Lapho i-valve yokulawula ikude negumbi lokulawula, kuyadingeka ukuhlomisa i-valve position transmitter, eguqula ukugudluka kwe-valve yokuvula ibe isignali kagesi futhi iyithumele ekamelweni lokulawula ngokuvumelana nomthetho onqunywe kusengaphambili, ukuze qonda kahle indawo yokushintsha ye-valve ngaphandle kokuya kusayithi.Isignali ingase ibe isignali eqhubekayo emele noma yikuphi ukuvulwa kwe-valve noma ingase ithathwe njengomsebenzi wokuhlehlisa isihleli se-valve.

Shintsha ukuxhumana ngenkathi usohambeni
Iswishi yomkhawulo iyingxenye edlulisela ngesikhathi esisodwa isignali yenkomba futhi ikhombisa izindawo ezimbili ezeqisayo zeswishi yevalvu.Igumbi lokulawula lingabika isimo sokushintshwa kwe-valve ngokusekelwe kule signali futhi lithathe isinyathelo esifanele.
