I-Positioner ye-electro-pneumatic Valve ehlakaniphile

I-valve positioner, isesekeli esiyinhloko se-valve elawulayo, i-valve positioner iyisesekeli esiyinhloko se-valve elawulayo, esetshenziselwa ukulawula izinga lokuvula kwe-valve yomoya noma kagesi ukuqinisekisa ukuthi i-valve ingayeka ngokunembile lapho ifika endaweni enqunyiwe. Ngokulawula okunembile kwe-valve positioner, ukulungiswa okunembile koketshezi kungafinyelelwa ukuze kuhlangatshezwane nezidingo zezinqubo ezahlukene zezimboni. Ama-valve positioner ahlukaniswe ngama-valve positioner omoya, ama-valve positioner omoya kanye nama-valve positioner ahlakaniphile ngokwesakhiwo sawo. Athola isignali yokukhipha yomlawuli bese esebenzisa isignali yokukhipha ukulawula i-valve elawulayo yomoya. Ukufuduka kwesiqu se-valve kubuyiselwa ku-valve positioner ngedivayisi yomshini, futhi isimo se-valve position sidluliselwa ohlelweni oluphezulu ngesignali kagesi.

Ama-valve positioners omoya ayindlela eyisisekelo kakhulu, amukela futhi adlulisele izimpawu ngamadivayisi emishini.

I-valve positioner ye-electro-pneumatic ihlanganisa ubuchwepheshe kagesi kanye ne-pneumatic ukuthuthukisa ukunemba kanye nokuguquguquka kokulawula.
I-valve positioner ehlakaniphile yethula ubuchwepheshe be-microprocessor ukuze kufezwe ukuzenzekela okuphezulu kanye nokulawula okuhlakaniphile.
Ama-valve positioners adlala indima ebalulekile ezinhlelweni zokwenza izinto ngokuzenzakalela kwezimboni, ikakhulukazi ezimweni lapho kudingeka khona ukulawulwa okunembile kokugeleza koketshezi, njengezimboni zamakhemikhali, uphethiloli, kanye negesi yemvelo. Athola izimpawu ezivela ohlelweni lokulawula futhi alungise ngokunembile ukuvulwa kwevalvu, ngaleyo ndlela alawule ukugeleza koketshezi futhi ahlangabezane nezidingo zezinqubo ezahlukahlukene zezimboni.
