I-valve positioner iyisisekeli esiyinhloko sama-actuator we-pneumatic. Isetshenziswa ngokubambisana nama-actuator we-pneumatic ukuze kuthuthukiswe ukunemba kokubeka ama-valve futhi kunqobe imiphumela ye-stem friction namandla angalingani avela phakathi nendawo, ukuqinisekisa ukuthi i-valve ibekwe ngokunembile ngokuvumelana nezimpawu ezivela kumlawuli.

I-positioner kufanele isetshenziswe ezimweni ezilandelayo:

Lapho ukucindezela okuphakathi kuphezulu futhi kunomehluko omkhulu wengcindezi.

Lapho usayizi wevalvu mkhulu (DN> 100).

Kumavalvu okulawula izinga lokushisa eliphezulu noma izinga lokushisa eliphansi.

Lapho kunesidingo sokwandisa isivinini sokusebenza se-valve yokulawula.

Uma usebenzisa amasiginali ajwayelekile futhi usebenzisa amabanga entwasahlobo angajwayelekile (iziphethu ezingaphandle kobubanzi obungu-20-100KPa).

Uma isetshenziselwa ukulawula okuhleliwe.

Lapho ufinyelela isenzo sevalvu ehlehlayo (isb, ukushintsha phakathi kokuvalwa komoya nokuvuleka komoya).

Lapho kunesidingo sokushintsha izici zokugeleza kwe-valve (ikhamera ye-positioner ingalungiswa).

Uma singekho i-actuator yasentwasahlobo noma i-piston actuator kanye nesenzo sokulinganisa siyadingeka.

Uma usebenzisa ama-actuator we-pneumatic anezimpawu zikagesi, kufanele kusetshenziswe indawo yokubeka i-valve yomoya kagesi.

I-Solenoid Valve:

Lapho uhlelo ludinga ukulawulwa kohlelo noma ukulawulwa kokucisha, kusetshenziswa amavalvu e-solenoid. Lapho ukhetha i-valve ye-solenoid, ngaphandle kokucabangela amandla kagesi e-AC noma e-DC, i-voltage, nemvamisa, kufanele kuqashelwe ubudlelwano obusebenzayo phakathi kwe-valve ye-solenoid kanye ne-valve yokulawula. Kungaba uhlobo oluvame ukuvuleka noma oluvamise ukuvaleka. Uma kudingekile ukwandisa umthamo we-valve ye-solenoid ukuze unciphise isikhathi sokuphendula, ama-valve amabili e-solenoid angasetshenziswa ngokuhambisana noma i-solenoid valve ingasetshenziswa njenge-valve yokushayela inhlanganisela ne-relay ye-pneumatic yomthamo omkhulu.

I-Pneumatic Relay:

I-pneumatic relay iyisikhulisamandla samandla esingadlulisela amasiginali womoya ezindaweni ezikude, sisuse ukuleleka okubangelwa amapayipi esignali amade. Isetshenziswa kakhulu phakathi kwama-transmitters asensimini kanye namakamelo okulawula amaphakathi okulawula amathuluzi, noma phakathi kwabalawuli namavalve okulawula insimu. Iphinde ibe nomsebenzi wokukhulisa noma ukunciphisa amasignali.

Isiguquli:

Iziguquli zihlukaniswe zibe iziguquli ze-pneumatic-electric kanye neziguquli zikagesi-womoya. Umsebenzi wabo ukuguqula phakathi kwezimpawu ze-pneumatic nezikagesi ngokuvumelana nobuhlobo obuthile. Asetshenziswa kakhulu lapho kusetshenziswa ama-actuator omoya anezimpawu zikagesi, aguqula amasiginali kagesi angu-0-10mA noma 4-20mA abe amasignali womoya angu-0-100KPa noma okuphambene nalokho, aguqula amasignali kagesi angu-0-10mA noma 4-20mA.

Isilawuli Sesihlungi Somoya:

Izilawuli zokuhlunga umoya ziyizesekeli ezisetshenziswa kumathuluzi ezishintshayo zezimboni. Umsebenzi wabo oyinhloko ukuhlunga nokuhlanza umoya ocindezelweyo osuka kuma-compressor emoyeni futhi uzinzise ukucindezela ngenani elidingekayo. Zingasetshenziswa njengemithombo yegesi kanye namadivayisi okuqinisa ingcindezi yezinsimbi ezihlukahlukene ze-pneumatic, ama-valve e-solenoid, amasilinda, imishini yokufutha, namathuluzi amancane omoya.

I-Valve Ezikhiyelayo (Indawo Yevalufu Yokukhiya):

I-valve yokuzikhiya iyisisetshenziswa esisetshenziselwa ukugcina indawo yevalvu. Lapho i-valve yokulawula umoya ithola ukwehluleka ekunikezeni komoya, le divayisi inganqamula isignali yomoya, igcine isignali yokucindezela egumbini le-diaphragm noma isilinda endaweni ngaphambi nje kokwehluleka. Lokhu kuqinisekisa ukuthi isikhundla se-valve sigcinwa endaweni ngaphambi kokuhluleka, sisebenzela inhloso yokukhiya isikhundla.

I-Valve Position Transmitter:

Uma i-valve yokulawula ikude negumbi lokulawula futhi kudingekile ukwazi ngokunembile indawo ye-valve ngaphandle kokuya ensimini, kufanele kufakwe i-valve position transmitter. Iguqula ukukhishwa kwendlela yokuvula i-valve ibe isignali kagesi ngokomthetho othile futhi iyithumele ekamelweni lokulawula. Le signali ingaba isignali eqhubekayo ebonisa noma yikuphi ukuvulwa kwe-valve, noma ingabhekwa njengesenzo esiphambene sesihleli sevalvu.

Ukushintsha Kokuhamba (Idivayisi Yempendulo Yendawo):

Iswishi yokuhamba ibonisa izindawo ezimbili ezeqisayo zevalvu futhi ngesikhathi esisodwa ithumela isignali yenkomba. Igumbi lokulawula linganquma isimo se-valve yokuvala ngokususelwe kule signali futhi lithathe izinyathelo ezihambisanayo.
