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. -
umda tshintsha ibhokisi-Valve Isikhundla Monitor -ukuhamba switsha
Ibhokisi yokutshintshela umda wevalve, ekwabizwa ngokuba yiValve Position Monitor okanye iswitshi yokuhamba ngevalve, sisixhobo esisetyenziselwa ukubona nokulawula indawo yokuvula nokuvala yevalve. Yahlulwe kwiindidi zoomatshini kunye nokusondele. imodeli yethu ibe Fl-2n, Fl-3n, Fl-4n, Fl-5n. Umda wokutshintsha ibhokisi yokuqhuma-ubungqina kunye namanqanaba okukhusela angahlangabezana nemigangatho yehlabathi.
Ukutshintshwa komda we-Mechanical kunokwahlulwa ngakumbi kwi-direct-acting, rolling, micro-motion kunye neentlobo ezidibeneyo ngokweendlela ezahlukeneyo zesenzo. Ukutshintshwa kwe-valve ye-Mechanical limits ngokuqhelekileyo kusebenzisa i-micro-motion switchs kunye nabafowunelwa be-passive, kwaye iifom zabo zokutshintsha zibandakanya i-pole-pole double-throw (SPDT), i-single-pole single-throw (SPST), njl.
Iiswitshi zomda wokusondele, okwaziwa ngokuba ziiswitshi zokuhamba ezingaqhagamshelwanga, izitshixo zomda wevalve yokungenisa imagnethi zihlala zisebenzisa i-electromagnetic induction proximity switches enoqhagamshelwano olungenakwenziwa. Iifom zayo zokutshintsha ziquka i-single-pole double-throw (SPDT), i-single-pole single-throw (SPST), njl.
