I-valve positioner sisixhobo esiphambili se-actuators zomoya. Isetyenziswa kunye ne-pneumatic actuators ukuphucula ukuchaneka kokubekwa kweevalvu kunye nokoyisa imiphumo yokungqubana kwesiqu kunye namandla angalinganiyo avela kwi-medium, ukuqinisekisa ukuba ivalvu ibekwe ngokuchanekileyo ngokwemiqondiso evela kumlawuli.

I-positioner kufuneka isetyenziswe kwezi meko zilandelayo:

Xa uxinzelelo oluphakathi luphezulu kwaye kukho umahluko omkhulu woxinzelelo.

Xa ubungakanani bevalvu bukhulu (DN > 100).

Kwiivalvu zokulawula ezishushu kakhulu okanye ezishushu kancinci.

Xa kukho imfuneko yokunyusa isantya sokusebenza kwevalvu yokulawula.

Xa usebenzisa imiqondiso eqhelekileyo kwaye usebenza kwiintlobo zentwasahlobo ezingezizo ezisemgangathweni (iintlobo zentwasahlobo ezingaphandle koluhlu lwe-20-100KPa).

Xa isetyenziselwa ulawulo olucwangcisiweyo.

Xa ufezekisa isenzo sevalvu yokubuyela umva (umz., ukutshintsha phakathi kokuvala umoya kunye nokuvula umoya).

Xa kukho imfuneko yokutshintsha iimpawu zokuhamba kwevalvu (i-positioner cam inokulungiswa).

Xa kungekho sixhobo sokuqalisa intwasahlobo okanye isixhobo sokuqalisa i-piston, kufuneka kwenziwe intshukumo elinganayo.

Xa usebenzisa ii-actuators zomoya ezinemiqondiso yombane, kufuneka kusetyenziswe i-electrical-air valve positioner.

Ivalvu yeSolenoid:

Xa inkqubo ifuna ulawulo lwenkqubo okanye ulawulo oluvuliweyo, kusetyenziswa iivalvu zesolenoid. Xa kukhethwa ivalvu yesolenoid, ngaphandle kokuqwalasela umbane we-AC okanye we-DC, i-voltage, kunye ne-frequency, kufuneka kuqwalaselwe ubudlelwane obusebenzayo phakathi kwevalvu yesolenoid kunye nevalvu yokulawula. Ingavulwa okanye ivalwe ngokuqhelekileyo. Ukuba kuyimfuneko ukwandisa amandla evalvu yesolenoid ukuze kuncitshiswe ixesha lokuphendula, iivalvu ezimbini zesolenoid zingasetyenziswa ngaxeshanye okanye ivalvu yesolenoid ingasetyenziswa njengevalvu yovavanyo kunye ne-relay yepneumatic enamandla amakhulu.

I-Relay ye-Pneumatic:

I-relay ye-pneumatic sisixhobo sokukhulisa amandla esinokudlulisela imiqondiso ye-pneumatic kwiindawo ezikude, sisuse ukushiyeka okubangelwa yimibhobho yesignali ende. Isetyenziswa kakhulu phakathi kwabathumeli bentsimi kunye namagumbi olawulo aphakathi ukuze kulawulwe izixhobo, okanye phakathi kwabalawuli kunye neevalvu zolawulo lwentsimi. Ikwanomsebenzi wokukhulisa okanye ukunciphisa imiqondiso.

Isiguquli:

IiConverters zahlulwe zaba zii-converters ze-pneumatic-electric kunye nee-converters ze-electric-pneumatic. Umsebenzi wazo kukuguqula phakathi kweempawu ze-pneumatic kunye neze-electric ngokwendlela ethile yobudlelwane. Zisetyenziswa kakhulu xa kusetyenziswa ii-actuators ze-pneumatic ezineempawu zombane, ziguqula izibonakaliso zombane ze-0-10mA okanye ze-4-20mA zibe ziimpawu ze-pneumatic ze-0-100KPa okanye ngokuchaseneyo, ziguqula izibonakaliso zombane ze-0-10mA okanye ze-4-20mA.

Umlawuli weFilter yoMoya:

Izilawuli zezihluzi zomoya zizixhobo ezisetyenziswa kwizixhobo zokwenza izinto ngokuzenzekelayo kwimizi-mveliso. Umsebenzi wazo ophambili kukucoca nokucoca umoya ocinezelweyo kwiicompressor zomoya kunye nokuzinzisa uxinzelelo ngexabiso elifunekayo. Zingasetyenziswa njengemithombo yegesi kunye nezixhobo zokuzinzisa uxinzelelo kwizixhobo ezahlukeneyo zomoya, iivalvu zesolenoid, iisilinda, izixhobo zokutshiza, kunye nezixhobo ezincinci zomoya.

Ivalvu Ezivalelayo (Ivalvu Yokutshixa Indawo):

Ivalvu ezitshixayo sisixhobo esisetyenziselwa ukugcina indawo yevalvu. Xa ivalvu yokulawula umoya ifumana ukungasebenzi kakuhle komoya, esi sixhobo sinokunqumla isignali yomoya, sigcine isignali yoxinzelelo kwigumbi le-diaphragm okanye kwisilinda kwimeko ngaphambi nje kokuba ingasebenzi. Oku kuqinisekisa ukuba indawo yevalvu igcinwa kwindawo ngaphambi kokuba ingasebenzi, isebenzela injongo yokutshixa indawo.

Umthumeli wesikhundla seValve:

Xa ivalvu yokulawula ikude negumbi lolawulo kwaye kuyimfuneko ukwazi ngokuchanekileyo indawo yevalvu ngaphandle kokuya entsimini, kufuneka kufakwe itransmitter yendawo yevalvu. Iguqula ukufuduka kwendlela yokuvula ivalvu ibe yisignali yombane ngokomthetho othile kwaye iyithumele kwigumbi lolawulo. Le signali inokuba yisignali eqhubekayo ebonisa naluphi na ukuvulwa kwevalvu, okanye ingathathwa njengesenzo esichaseneyo sendawo yevalvu.

Utshintsho lokuHamba (Isixhobo sokuBuya kwindawo ethile):

Iswitshi yokuhamba ibonisa iindawo ezimbini ezikude zevalvu kwaye ngaxeshanye ithumela isignali yokubonisa. Igumbi lolawulo linokumisela imeko yokuvala kwevalvu ngokusekelwe kolu phawu kwaye lithathe amanyathelo afanelekileyo.
