Ngokuvamile kubalulekile ukuhlela izinto ezisizayo ezahlukene ngenkathi kusetshenziswa ama-valve omoya ukuze kuthuthukiswe ukusebenza kwawo noma ukusebenza kahle kwawo. Izihlungi zomoya, ama-valve e-solenoid aguqulayo, ama-switch omkhawulo, ama-positioner kagesi, njll. ziyizesekeli ezijwayelekile zama-valve omoya. Isihlungi somoya,ivalvu yokunciphisa ingcindezi, kanye ne-lubricator kuyizingxenye ezintathu zokucubungula umthombo womoya ezihlanganiswe njengezingxenye ezintathu zomoya kubuchwepheshe be-pneumatic. Lezi zingxenye zisetshenziselwa ukuhlanza nokuhlunga umthombo womoya ongena entweni yomoya bese uyikhipha emthonjeni womoya olinganiselwe wento. I-transformer yamandla esesekethe isebenza ngendlela efana nengcindezi.

Izinhlobo ezahlukene ze-pneumaticivalvuokunamathiselwe

Ukulawula ukuvula nokuvala ivalvu enezindawo ezimbili nge-actuator esebenza kabili. (i-entender ephindwe kabili)

Uma isekethe yomoya yesekethe ivaliwe noma yehluleka,ivalvuizovula noma ivale ngokuzenzakalelayo ngenxa ye-actuator yokubuyisela intwasahlobo. (Isebenza ngendlela efanayo)

I-valve eyodwa ye-solenoid: uma kusetshenziswa ugesi, i-valve iyavuleka noma iyavaleka; uma ugesi ususwa, i-valve iyavuleka noma iyavaleka (uhlobo oluvikela ukuqhuma luyatholakala).

I-valve ye-solenoid ephindwe kabili enomsebenzi wememori kanye nokwakhiwa okuvimbela ukuqhuma evuleka lapho ikhoyili eyodwa inikwa amandla futhi ivale lapho enye ikhoyili inikwa amandla.

Idivayisi yokuphendula nge-switch ekhawulelwe: xhumana nesignali yesikhundla se-switch se-valve ngebanga elide (amamodeli angaqhumi nawo ayatholakala).

I-Electric positioner: Ilungisa futhi ilawula ukugeleza okuphakathi kwevalvu (uhlobo olungaqhumi luyatholakala) ngokuhambisana nosayizi wesignali yamanje (ejwayelekile engu-4-20mA).

Isikhundla somoya: shintsha futhi ulawule ukuhamba okuphakathi kwevalvu ngokuhambisana nosayizi wesignali yomfutho womoya (enelebula engu-0.02-0.1MPa).
Isiguquli sikagesi (inguqulo engaqhumi iyatholakala): Guqula isignali yamanje ibe isignali yokucindezela komoya ukuze isetshenziswe ne-pneumatic positioner.

Ukuze kuqiniswe ukuphakelwa komoya, kuhlanzwe futhi kugcotshwe izingxenye ezihambayo, ukwelashwa komthombo womoya kuhlanganisa izingxenye ezintathu: ivalvu yokwehlisa umfutho womoya, isihlungi, kanye ne-lubricator.

Indlela yokusebenza ngesandla: Ezimweni ezingavamile, ukulawula okuzenzakalelayo kungasuswa ngesandla.

Ukukhetha izesekeli zama-valve omoya:

Ama-valve omoya ayimishini yokulawula ezenzakalelayo eyinkimbinkimbi eyenziwe ngezingxenye ezahlukene zomoya. Abasebenzisi kumele bakhethe ngokucophelela ngokusekelwe ezidingweni zokulawula.

1. Uhlobo olusebenza kabili, uhlobo olusebenza kanye, incazelo yemodeli, kanye nesikhathi sesenzo sama-actuator omoya.

2. I-valve ye-solenoid yokulawula eyodwa, i-valve ye-solenoid yokulawula okuphindwe kabili, i-voltage yokusebenza, kanye nama-valve e-solenoid angenakuqhuma ayatholakala.

3. Impendulo yesiginali ihlanganisa okulandelayo: iswishi yomshini, iswishi yokusondela, isiginali yamanje yokuphuma, i-voltage yokusetshenziswa, kanye nohlobo olungaqhumi.

4. Indawo: kagesi eyodwa, omoya ababili, ugesi ongu-8, umfutho womoya ongu-4, i-converter kagesi engu-5, kanye nezinhlobo eziyisithupha ezingaqhumi.

5. Ukwelashwa komthombo womoya ngezingxenye ezintathu: izithambisi ezimbili kanye nevalvu yokunciphisa umfutho wesihlungi.

6. Indlela yokusebenza ngesandla.
