I-valve positioner iyisengezo esiyinhloko sama-actuator omoya. Isetshenziswa kanye nama-actuator omoya ukuthuthukisa ukunemba kokubekwa kwama-valve nokunqoba imiphumela yokungqubuzana kwesiqu kanye namandla angalingani avela ku-medium, ukuqinisekisa ukuthi i-valve ibekwe kahle ngokwezimpawu ezivela kumlawuli.

I-positioner kufanele isetshenziswe ezimweni ezilandelayo:

Uma ingcindezi ephakathi nendawo iphezulu futhi kukhona umehluko omkhulu wengcindezi.

Uma usayizi wevalvu mkhulu (DN > 100).

Kumavalvu okulawula okushisa okuphezulu noma okushisa okuphansi.

Uma kunesidingo sokwandisa ijubane lokusebenza kwevalvu yokulawula.

Uma usebenzisa izimpawu ezijwayelekile futhi usebenzisa amabanga entwasahlobo angewona ajwayelekile (iziphethu ezingaphandle kwebanga elingu-20-100KPa).

Uma isetshenziswa ukulawula okuhleliwe.

Uma ufeza isenzo se-valve yokubuyela emuva (isb., ukushintsha phakathi kokuvala umoya kanye nokuvula umoya).

Uma kunesidingo sokushintsha izici zokugeleza kwevalvu (ikhamera yesikhundla ingalungiswa).

Uma kungekho i-spring actuator noma i-piston actuator futhi kudingeka isenzo esilinganayo.

Uma usebenzisa ama-actuator omoya anezimpawu zikagesi, kufanele kusetshenziswe i-electric-air valve positioner.

I-Valve ye-Solenoid:

Uma uhlelo ludinga ukulawulwa kohlelo noma ukulawulwa kokuvula, kusetshenziswa ama-valve e-solenoid. Uma ukhetha i-valve ye-solenoid, ngaphandle kokucabangela ukunikezwa kwamandla e-AC noma e-DC, i-voltage, kanye nemvamisa, kufanele kunakwe ubudlelwano obusebenzayo phakathi kwe-valve ye-solenoid ne-valve yokulawula. Ingavulwa noma ivalwe ngokuvamile. Uma kudingeka ukwandisa amandla e-valve ye-solenoid ukuze kufinyezwe isikhathi sokuphendula, ama-valve amabili e-solenoid angasetshenziswa ngokuhambisana noma i-valve ye-solenoid ingasetshenziswa njenge-valve yokushayela indiza ehlanganiswe ne-relay ye-pneumatic enamandla amakhulu.

I-Relay yomoya:

I-relay ye-pneumatic iyi-amplifier yamandla engadlulisela izimpawu zomoya ezindaweni ezikude, isuse ukulibaziseka okubangelwa amapayipi amade esignali. Isetshenziswa kakhulu phakathi kwama-transmitter asensimini namakamelo okulawula aphakathi ukuze kulawulwe izinsimbi, noma phakathi kwabalawuli nama-valve okulawula insimu. Iphinde ibe nomsebenzi wokukhulisa noma ukunciphisa izimpawu.

Isiguquli:

Ama-converter ahlukaniswe ngama-converter e-pneumatic-electric kanye nama-converter e-electric-pneumatic. Umsebenzi wawo ukuguqula phakathi kwamasignali e-pneumatic kanye ne-electric-pneumatic ngokuya ngobuhlobo obuthile. Asetshenziswa kakhulu lapho kusetshenziswa ama-actuator e-pneumatic anezimpawu zikagesi, ukuguqula amasignali kagesi angu-0-10mA noma angu-4-20mA abe amasignali e-pneumatic angu-0-100KPa noma okuphambene nalokho, ukuguqula amasignali kagesi angu-0-10mA noma angu-4-20mA.

Umlawuli Wezihlungi Zomoya:

Izilawuli zezihlungi zomoya ziyizesekeli ezisetshenziswa ezinsimbini zokwenza izinto ngokuzenzakalela kwezimboni. Umsebenzi wazo oyinhloko ukuhlunga nokuhlanza umoya ocindezelwe kuma-compressor omoya nokuqinisa ingcindezi ngenani elidingekayo. Zingasetshenziswa njengemithombo yegesi kanye namadivayisi okuqinisa ingcindezi ezinsimbini ezahlukahlukene zomoya, ama-valve e-solenoid, amasilinda, imishini yokufafaza, kanye namathuluzi amancane omoya.

Ivalvu Ezivalelayo (Ivalvu Yokukhiya Indawo):

I-valve ezikhiyayo iyithuluzi elisetshenziselwa ukugcina indawo ye-valve. Lapho i-valve yokulawula umoya ihlangabezana nokwehluleka kokunikezwa komoya, le divayisi inganqamula isignali yomoya, igcine isignali yokucindezela ekamelweni le-diaphragm noma kwisilinda esimweni ngaphambi nje kokwehluleka. Lokhu kuqinisekisa ukuthi indawo ye-valve igcinwa endaweni ngaphambi kokwehluleka, kufeza injongo yokukhiya indawo.

Isidluliseli Sesikhundla Sevalvu:

Uma i-valve yokulawula ikude negumbi lokulawula futhi kudingeka ukwazi ngokunembile indawo ye-valve ngaphandle kokuya ensimini, kufanele kufakwe i-transmitter yesikhundla se-valve. Iguqula ukufuduka kwendlela yokuvula i-valve ibe isignali kagesi ngokuya ngomthetho othile bese iyithumela egumbini lokulawula. Lesi signali singaba isignali eqhubekayo ekhombisa noma yikuphi ukuvulwa kwe-valve, noma singabhekwa njengesenzo esiphambene ne-valve positioner.

Ukushintsha Kokuhamba (Idivayisi Yempendulo Yesikhundla):

Iswishi yokuhamba ikhombisa izikhundla ezimbili ezikude zevalvu futhi ithumela isignali yokubonisa ngasikhathi sinye. Igumbi lokulawula linganquma isimo sokusebenza kwevalvu ngokusekelwe kulesi signali bese lithatha izinyathelo ezifanele.
