Izinhlobo kanye nokukhethwa kwezesekeli ze-valve yomoya

Enqubweni yokusebenzisa i-I-Velve Yomoya, ngokuvamile kuyadingeka ukumisa ezinye izingxenye ezisizayo ukuze kuthuthukiswe ukusebenza kwevalvu yomoya, noma kuthuthukiswe ukusebenza kahle kokusetshenziswa kwevalvu yomoya. Izesekeli ezivamile zamavalvu omoya zifaka: izihlungi zomoya, amavalvu e-solenoid aguqulayo, izinkinobho zomkhawulo, ama-positioner kagesi, njll. Kubuchwepheshe be-pneumatic, izakhi ezintathu zokucubungula umthombo womoya wesihlungi somoya, ivalvu yokunciphisa ingcindezi kanye no-oyela mister zihlanganiswa ndawonye, ​​okubizwa ngokuthi i-pneumatic triple piece. Isetshenziselwa ukungena emthonjeni womoya ukuze kuhlanzwe futhi kuhlungwe ithuluzi lomoya futhi kuncishiswe ingcindezi entweni ukuze kunikezwe umthombo womoya olinganisiwe. Ingcindezi ilingana nomsebenzi we-transformer yamandla kwisekethe.

Izinhlobo Zezesekeli Ze-Pneumatic Valve:

I-Actuator ye-Pneumatic esebenza kabili:

Ukulawula okunezikhundla ezimbili kokuvula nokuvala ivalvu. (Ukusebenza kabili)

I-actuator ye-pneumatic yokubuya kwentwasahlobo:

Ivalvu iyavuleka noma ivale ngokuzenzakalelayo lapho isekethe yegesi yesekethe inqanyulwa noma ingasebenzi kahle. (Isebenza kanye kuphela)

I-valve eyodwa ye-solenoid elawulwa ngogesi:

Ivalvu iyavuleka noma ivale lapho kunikezwa amandla, bese ivala noma ivula ivalvu lapho amandla elahleka (kukhona izinhlobo ezingamelani nokuqhuma).

I-valve ye-solenoid elawulwa ngogesi kabili:

Ivalvu iyavuleka uma ikhoyili eyodwa inikwe amandla, bese ivalvu iyavaleka uma ikhoyili enye inikwe amandla. Inomsebenzi wememori (uhlobo olungenasivikelo luyatholakala).

Ibhokisi Lokushintsha Umkhawulo:

Ukudluliswa kwebanga elide kwesignali yesikhundla sokushintsha sevalvu (enohlobo oluvikela ukuqhuma).

Isibekeli Sikagesi:

Lungisa futhi ulawule ukugeleza okuphakathi kwevalvu ngokuya ngobukhulu besiginali yamanje (ejwayelekile engu-4-20mA) (enohlobo oluvikela ukuqhuma).

Isikhundla Somoya:

Lungisa futhi ulawule ukugeleza okuphakathi kwevalvu ngokuya ngobukhulu besiginali yokucindezela komoya (ejwayelekile engu-0.02-0.1MPa).

Isiguquli sikagesi:

Iguqula isignali yamanje ibe isignali yokucindezela komoya. Isetshenziswa kanye ne-pneumatic positioner (enohlobo oluvikela ukuqhuma).

I-FRL (Isihlungi Somoya, I-Valvu Yokulawula, I-Lubricator):

Isihlungi Somoya (F): isetshenziselwa ukuhlunga ukungcola kanye nomswakama emoyeni ocindezelwe ukuqinisekisa ukuhlanzeka kohlelo lomoya.

I-Valve Yokulawula (R): isetshenziselwa ukunciphisa igesi enomfutho ophezulu iye ekucindezelweni okudingekayo ukuqinisekisa ukusebenza okuvamile kwezingxenye zomoya.

‌I-Lubricator (L): isetshenziselwa ukufaka inani elifanele lamafutha okugcoba ohlelweni lomoya ukuze kuncishiswe ukungqubuzana futhi kwandiswe isikhathi sokuphila kwemishini.

Lezi zingxenye zivame ukusetshenziswa ndawonye, ​​​​ezibizwa ngokuthi i-pneumatic triplex (FRL), edlala indima yokuhlanzwa, ukuhlunga kanye nokunciphisa ingcindezi kubuchwepheshe be-pneumatic.

Indlela Yokusebenza Ngesandla:

Ukulawula okuzenzakalelayo kungasetshenziswa ngesandla ngaphansi kwezimo ezingavamile.

Ukukhethwa Kwezesekeli Ze-Pneumatic Valve

I-Pneumatic Valve iyithuluzi lokulawula elizenzakalelayo eliyinkimbinkimbi. Lakhiwe ngezingxenye ezahlukahlukene zomoya. Abasebenzisi badinga ukwenza ukukhetha okuningiliziwe ngokuya ngezidingo zokulawula.

1. I-actuator yomoya:

Uhlobo lokulingisa kabili
Uhlobo olulodwa lokulingisa
Imininingwane yemodeli
Isikhathi sesenzo

2. I-valve ye-solenoid:

I-valve ye-solenoid yokulawula eyodwa
I-valve ye-solenoid yokulawula okubili
I-voltage yokusebenza
Uhlobo olungaqhumi

Impendulo Yesignali:

Iswishi yemishini
Iswishi yokusondela
Isignali yamanje yokukhipha
Ukusebenzisa i-voltage
Uhlobo olungaqhumi

4. Isifaki-ndawo:

I-positioner kagesi
Isikhundla somoya
Isignali yamanje
Isignali yokucindezela komoya
Isiguquli sikagesi
Uhlobo olungaqhumi

5. Izingxenye Ezintathu ze-FRL:

Hlunga
I-valve yokunciphisa ingcindezi
Idivayisi yenkungu egcotshwe ngotshani

6. Indlela yokusebenza ngesandla.
