I-Intelligent Valve electro-pneumatic Positioner

I-valve positioner , i-accessory eyinhloko ye-valve elawulayo, i-valve positioner iyisesekeli esiyinhloko se-valve elawulayo, esetshenziselwa ukulawula izinga lokuvula le-valve yomoya noma kagesi ukuze kuqinisekiswe ukuthi i-valve ingamisa ngokunembile lapho ifinyelela okunqunywe kusengaphambili. isikhundla. Ngokulawulwa okunembile kwesimo se-valve, ukulungiswa okunembile koketshezi kungafinyelelwa ukuze kuhlangatshezwane nezidingo zezinqubo ezihlukahlukene zezimboni. Ama-valve positioners ahlukaniswe abe ama-valve positioners womoya, ama-electro-pneumatic valve positioners kanye nama-valve positioners ahlakaniphile ngokwesakhiwo sawo. Bathola isignali yokuphuma yesilawuli bese besebenzisa isignali yokuphumayo ukuze balawule i-valve yokulawula umoya. Ukususwa kwesiqu se-valve kubuyiselwa endaweni yokubeka i-valve ngomshini owumshini, futhi isimo sokuma kwevalvu sidluliselwa ohlelweni olungaphezulu ngesignali kagesi.

Ama-valve omoya womoya awuhlobo oluyisisekelo kakhulu, oluthola futhi olunikeza amasiginali ngokusebenzisa imishini eyimishini.

I-electro-pneumatic valve positioner ihlanganisa ubuchwepheshe bukagesi kanye ne-pneumatic ukuthuthukisa ukunemba nokuguquguquka kokulawula.
I-valve positioner ehlakaniphile yethula ubuchwepheshe be-microprocessor ukuze kuzuzwe okuzenzakalelayo okuphezulu nokulawula okuhlakaniphile.
Ama-valve positioning adlala indima ebalulekile ezinhlelweni ezishintshayo zezimboni, ikakhulukazi ezimeni lapho kudingeka khona ukulawulwa okunembile kokugeleza koketshezi, njengezimboni zamakhemikhali, ze-petroleum, negesi yemvelo. Bathola amasignali ohlelweni lokulawula futhi balungise ngokunembile ukuvulwa kwe-valve, ngaleyo ndlela balawule ukugeleza kwamanzi futhi bahlangabezane nezidingo zezinqubo ezihlukahlukene zezimboni.
