Enkambweni yokusebenzisa i-valve ye-pneumatic, ngokuvamile kuyadingeka ukulungisa ezinye izingxenye ezisizayo ukuze kuthuthukiswe ukusebenza kwe-valve ye-pneumatic, noma ukuthuthukisa ukusebenza kahle kokusetshenziswa kwe-valve yomoya. Izesekeli ezivamile zamavalvu womoya zihlanganisa: izihlungi zomoya, amavalvu e-solenoid ahlehlayo, ukushintsha komkhawulo, izindawo zokubeka ugesi, njll. Kubuchwepheshe bomoya, izingxenye ezintathu zokucubungula umthombo womoya wesihlungi somoya, i-valve yokunciphisa umfutho kanye ne-mister kawoyela kuhlanganiswe ndawonye, ​​​​okubizwa ngokuthi pneumatic ucezu kathathu. Isetshenziselwa ukufaka umthombo womoya ukuze kuhlanzwe futhi kuhlungwe insimbi yomoya kanye nokunciphisa ukucindezela kwethuluzi ukuze kunikeze umthombo womoya olinganiselwe Ukucindezela kulingana nomsebenzi we-transformer yamandla kumjikelezo.

Izinhlobo zezesekeli ze-valve ye-pneumatic:

I-actuator ye-pneumatic esebenza kabili: Ukulawulwa kwezindawo ezimbili zokuvula nokuvala i-valve. (Ulingisa kabili)

I-actuator ye-Spring-return: Ivalvu ivula noma ivaleke ngokuzenzakalelayo lapho isifunda segesi yesifunda sisikwa noma singasebenzi kahle. (Single acting)

Ivalvu ye-solenoid eyodwa elawulwa nge-elekthronikhi: Ivalvu ivula noma ivale lapho kunikezwa amandla, futhi ivale noma ivule ivalvu lapho amandla elahlekile (izinguqulo ezivikela ukuqhuma ziyatholakala).

Ivalvu ye-solenoid elawulwa nge-elekthronikhi kabili: Ivalvu iyavuleka lapho ikhoyili eyodwa inamandla, futhi ivalvu ivaleka lapho enye ikhoyili inikwa amandla. Inomsebenzi wenkumbulo (uhlobo lobufakazi bangaphambili luyatholakala).

I-echo yokushintsha umkhawulo: Ukudluliselwa kwebanga elide kwesignali yendawo yokushintsha yevalvu (nohlobo lokuvikela ukuqhuma).

Indawo kagesi: Lungisa futhi ulawule ukugeleza okuphakathi kwe-valve ngokosayizi wesignali yamanje (okujwayelekile okungu-4-20mA) (nohlobo lokuvikela ukuqhuma).

I-pneumatic positioner: Lungisa futhi ulawule ukugeleza okuphakathi kwe-valve ngokobukhulu besignali yokucindezela komoya (okujwayelekile 0.02-0.1MPa).

Isiguquli sikagesi: Siguqula isignali yamanje ibe isignali yokucindezela komoya. Isetshenziswa kanye ne-pneumatic positioner (nohlobo lokuvikela ukuqhuma).

Ukucubungula umthombo womoya izingxenye ezintathu: okuhlanganisa i-valve yokunciphisa umfutho womoya, isihlungi, idivayisi yenkungu kawoyela, ukuqiniswa kwengcindezi, ukuhlanza nokugcobisa izingxenye ezihambayo.

Indlela yokusebenza eyenziwa mathupha: Ukulawula okuzenzakalelayo kungenziwa mathupha ngaphansi kwezimo ezingavamile.

Ukukhetha izesekeli ze-valve ye-pneumatic:

I-valve ye-pneumatic iyithuluzi lokulawula elizenzakalelayo eliyinkimbinkimbi. Yakhiwe ngezinhlobonhlobo zezingxenye zomoya. Abasebenzisi badinga ukukhetha okuningiliziwe ngokuya ngezidingo zokulawula.

1. I-Actuator yomoya: ① ​​uhlobo olusebenza kabili, ② uhlobo olulodwa lokulingisa, ③ ukucaciswa kwemodeli, ④ isikhathi sesenzo.

2. I-valve ye-Solenoid: ① isilawuli esisodwa se-solenoid valve, ② isilawuli esikabili solenoid valve, ③ i-voltage esebenzayo, ④ uhlobo olungaqhumi

3. Impendulo yesiginali: ① iswishi yomshini, ② iswishi yokuba seduze, ⑧ isignali yamanje ephumayo, ④ kusetshenziswa i-voltage, ⑤ uhlobo lokuvikela ukuqhuma

4. Indawo: ① indawo kagesi, ② indawo yomoya, ⑧ isignali yamanje, ④ isignali yomfutho womoya, ⑤ isiguquli sikagesi, ⑥ uhlobo olungaqhumi.

5. Izingxenye ezintathu zokwelapha umthombo womoya: ① ​​isihlungi sokunciphisa i-valve, ② idivayisi yenkungu kawoyela.

6. Indlela yokusebenza ngezandla.
