Imuphi umehluko phakathi komthombo wegesi i-triplex kanye ne-pneumatic triplex?

I-pneumatic valve actuator ingumoya ocindezelwe njengamandla okuvula nokuvala. Ama-valve ebhola womoya, ama-valve ovemvane womoya, ama-valve esango lomoya, ama-valve eglobhu womoya, ama-diaphragm womoya, ama-valve okulawula umoya kanye nolunye uchungechunge lwe-pneumatic yedivayisi ye-angular stroke drive. Iwukufinyelela ukulawulwa kwepayipi ebangeni elide endaweni eyodwa noma ehlukene yepayipi lemishini ezishintshayo yezimboni yedivayisi efanelekile.

Abanye abantu kulula kakhulu ukudida umthombo wegesi i-triplex kanye ne-pneumatic triplex. Ngicabanga ukuthi umehluko phakathi kwakho kokubili ukuthi umthombo wegesi kathathu ngesihlungi, i-valve yokunciphisa ingcindezi, inkungu kawoyela, izingxenye ezintathu. kuyilapho i-triplex ye-pneumatic yomthombo wegesi i-triplex, ama-switch switch, ama-solenoid valves akhiwe izingxenye ezintathu, umthombo wegesi i-triplex iyi-triplex yomoya ngaphakathi kwezingxenye zengxenye.

Isihlungi iyisisetshenziswa sokuhlanza umoya, esihluza amanzi nokungcola okusemoyeni. Ama-actuator we-pneumatic ukwenza umsebenzi, izingxenye ezibalulekile. uma kungenjalo ukuhogela kwe-pneumatic actuator kokungcola kuzothinta ukusetshenziswa komsebenzi wayo nempilo yesevisi.

I-valve yokunciphisa ingcindezi iwukuba ulungise ingcindezi yomthombo womoya ukuze kuzuzwe ukuzinza kwengcindezi, ngemva kokuba i-valve yokunciphisa ingcindezi ukulungisa ingcindezi ifanelekile, ukusetshenziswa kwedivayisi yokukhiya. Indima ye-atomizer kawoyela ukuthumela uwoyela ngepayipi legesi kusilinda ukuze kufezwe inhloso yokugcoba isilinda.

Ama-valve e-Solenoid ayizingxenye eziyinhloko zezingxenye zokulawula umoya. ngama-valve e-solenoid angabona isilawuli kude. Ama-valve e-Solenoid asetshenziselwa i-valve ye-pneumatic "open" noma "vala" ukusebenza kokulawula ugesi. Ngokuhambisana nezindinganiso zokuxhuma ze-NAMUR, zifakwe ngokuqondile ohlangothini lwe-actuator ye-pneumatic, ngaphandle kwesidingo sokuxhuma kwepayipi. Ngokwesistimu yokulawula i-instrumentation idinga ukukhetha isilawuli esisodwa sikagesi noma isilawuli sikagesi esiphindwe kabili. I-valve ye-solenoid enezinhlangothi ezimbili enezinhlangothi ezinhlanu ene-actuator esebenza kabili, i-valve ye-solenoid enezinhlangothi ezimbili ene-actuator eyodwa, wonke umshini ulula, uhlangene, umthamo omncane, impilo ende. Umkhiqizo unohlobo oluyisisekelo (IP67) kanye nohlobo lokuvikela ukuqhuma, izinga lokuvikela ukuqhuma i-ExdIIBT4, futhi izinga layo lokuvikela ukuqhuma lifanele izimboni.

I-Limit switch, iyithuluzi lokubonisa isimo se-valve, iyisiginali yokuxhumana eshintshayo, impendulo ohlelweni lokulawula kude.

I-Positioner, kune-positioner kagesi kanye ne-pneumatic positioner. indawo kagesi isekelwe kusayizi wesiginali yamanje 4 ~ 20mA kumthethonqubo wokugeleza kwemidiya ye-valve nokulawula. ngokuphambene nalokho, isikhundla somoya sisekelwe kusayizi wesiginali ye-pneumatic 0.02 ~ 0.1MPa kumthethonqubo wokugeleza kwemidiya ye-valve nokulawula.
