I-Valve ehlakaniphile ye-electro-pneumatic Positioner

I-valve positioner , i-accessory ephambili ye-valve yokulawula, i-valve positioner iyona nto iphambili ye-valve yokulawula, esetyenziselwa ukulawula iqondo lokuvula i-valve ye-pneumatic okanye yombane ukuqinisekisa ukuba i-valve inokumisa ngokuchanekileyo xa ifikelela kwi-predetermined. isikhundla. Ngolawulo oluchanekileyo lwe-valve positioner, ukulungiswa okuchanekileyo kolwelo kunokufezekiswa ukuhlangabezana neemfuno zeenkqubo ezahlukeneyo zoshishino. Izibonisi zevalvu zahlulwe ngokweendawo zokubeka iivalvu zepneumatic, i-electro-pneumatic valve positioners kunye neendawo ezinengqondo zevalvu ngokobume bazo. Bafumana umqondiso wokuphuma komlawuli kwaye basebenzise isignali yokuphuma ukulawula i-valve yokulawula i-pneumatic. Ukushenxiswa kwesikhondo sevalvu kubuyiselwa kwisimo sevalve ngesixhobo somatshini, kwaye ubume bendawo yevalvu bugqithiselwa kwisixokelelwano esiphezulu ngomqondiso wombane.

Iimpawu zevalve yepneumatic lolona didi lusisiseko, ukufumana kunye nokutyisa imiqondiso ngasemva ngezixhobo zoomatshini.

I-electro-pneumatic valve positioner idibanisa iteknoloji yombane kunye ne-pneumatic ukuphucula ukuchaneka kunye nokuguquguquka kokulawula.
I-valve positioner ekrelekrele yazisa itekhnoloji ye-microprocessor ukufezekisa i-automation ephezulu kunye nolawulo olukrelekrele.
Izibonisi zevalvu zidlala indima ebalulekileyo kwiinkqubo ezizisebenzelayo kwimizi-mveliso, ngakumbi kwiimeko apho kufuneka ulawulo oluchanekileyo lokuhamba kolwelo, njengemichiza, i-petroleum, kunye nemizi-mveliso yerhasi yendalo. Bafumana izibonakaliso kwinkqubo yokulawula kwaye balungise ngokuchanekileyo ukuvulwa kwe-valve, ngaloo ndlela belawula ukuhamba kwamanzi kunye nokuhlangabezana neemfuno zeenkqubo ezahlukeneyo zoshishino.
