I-valve positioner sisixhobo esiphambili se-actuator ye-pneumatic. Isetyenziswe ngokubambisana ne-actuator ye-pneumatic ukuphucula ukuchaneka kokumisa iivalve kunye nokunqoba imiphumo ye-stem friction kunye nemikhosi engalinganiyo ukusuka kwi-medium, ukuqinisekisa ukuba i-valve ibekwe ngokuchanekileyo ngokwemiqondiso evela kumlawuli.

Isikhundla kufuneka sisetyenziswe kwezi meko zilandelayo:

Xa uxinzelelo oluphakathi luphezulu kwaye kukho umahluko omkhulu woxinzelelo.

Xa ubukhulu bevalve bukhulu (DN> 100).

Kwiivalvu zokulawula ubushushu obuphezulu okanye obuphantsi.

Xa kukho imfuneko yokunyusa isantya sokusebenza sevalve yokulawula.

Xa usebenzisa imiqondiso esemgangathweni kunye nokusebenza kwemigangatho yentwasahlobo engekho-standard (imithombo engaphandle koluhlu lwe-20-100KPa).

Xa isetyenziselwa ulawulo lweqonga.

Xa kuphunyezwa intshukumo yevalvu ebuyela umva (umzekelo, ukutshintshela phakathi kokuvalwa komoya kunye nokuvulwa komoya).

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

Xa kungekho actuator yasentwasahlobo okanye ipiston actuator kunye nesenzo sokulingana siyafuneka.

Xa usebenzisa i-actuator ye-pneumatic enemiqondiso yombane, indawo yokubeka ivalve yombane kufuneka isetyenziswe.

Ivalve yeSolenoid:

Xa inkqubo idinga ulawulo lweprogram okanye ulawulo oluvaliweyo, iivalve ze-solenoid zisetyenziswa. Xa ukhetha i-valve ye-solenoid, ngaphandle kokuqwalasela i-AC okanye i-DC amandla ombane, i-voltage, kunye ne-frequency, ingqalelo kufuneka ihlawulwe kubudlelwane obusebenzayo phakathi kwe-valve ye-solenoid kunye ne-valve yokulawula. Isenokuba luhlobo oluqhelekileyo oluvulekileyo okanye oluqhelekileyo oluvaliweyo. Ukuba kuyimfuneko ukunyusa umthamo we-valve ye-solenoid ukunciphisa ixesha lokuphendula, ii-valve ezimbini ze-solenoid zingasetyenziselwa ngokuhambelana okanye i-valve ye-solenoid ingasetyenziselwa njenge-valve yokuqhuba ngokudibanisa ne-relay ye-pneumatic enkulu.

I-Pneumatic Relay:

I-pneumatic relay yi-amplifier yamandla ekwazi ukuhambisa izibonakaliso ze-pneumatic kwiindawo ezikude, ukuphelisa i-lag ebangelwa yimibhobho yesignali ende. Isetyenziswa kakhulu phakathi kwee-transmitters zentsimi kunye namagumbi okulawula aphakathi kwizixhobo zokulawula, okanye phakathi kwabalawuli kunye neevalve zokulawula intsimi. Kananjalo inomsebenzi wokukhulisa okanye ukunciphisa imiqondiso.

Isiguquli:

Abaguquleli bahlulwe babaguquleli be-pneumatic-electric kunye nabaguquleli bombane-womoya. Umsebenzi wabo kukuguqula phakathi kweempawu ze-pneumatic kunye nombane ngokobudlelwane obuthile. Zisetyenziswa kakhulu xa zisebenza ii-actuator ze-pneumatic ezinemiqondiso yombane, ukuguqula i-0-10mA okanye i-4-20mA imiqondiso yombane kwi-0-100KPa izibonakaliso ze-pneumatic okanye ngokuphambeneyo, ukuguqula i-0-10mA okanye i-4-20mA imiqondiso yombane.

UMlawuli wesihluzi soMoya:

Izilawuli zokucoca umoya zizincedisi ezisetyenziswa kwizixhobo ezizisebenzelayo zoshishino. Umsebenzi wabo oyintloko kukucoca kunye nokucoca umoya oxinzelelweyo kwiicompressor zomoya kunye nokuzinzisa uxinzelelo kwixabiso elifunekayo. Zingasetyenziswa njengemithombo yegesi kunye nezixhobo zokuzinzisa uxinzelelo kwizixhobo ezahlukeneyo ze-pneumatic, iivalve ze-solenoid, iisilinda, izixhobo zokutshiza, kunye nezixhobo ezincinci zomoya.

Ivalufa yokuZitshixa (iNdawo yeValve yokutshixa):

Ivalve yokuzivalela sisixhobo esisetyenziselwa ukugcina indawo yevalve. Xa i-valve yokulawula i-pneumatic ifumana ukungaphumeleli kunikezelo lomoya, esi sixhobo sinokunqumla isignali yomoya, ukugcina uphawu loxinzelelo kwigumbi le-diaphragm okanye i-cylinder kurhulumente ngaphambi nje kokungaphumeleli. Oku kuqinisekisa ukuba indawo ye-valve igcinwa kwindawo phambi kokungaphumeleli, ikhonza injongo yokuvala indawo.

Isidluliseli seNdawo yeValve:

Xa i-valve yokulawula ikude negumbi lokulawula kwaye kuyimfuneko ukwazi ngokuchanekileyo indawo yevalve ngaphandle kokuya kwintsimi, i-valve position transmitter kufuneka ifakwe. Iguqula ukuchithwa kwendlela yokuvula i-valve ibe ngumqondiso wombane ngokomgaqo othile kwaye uyithumele kwigumbi lokulawula. Olu phawu lunokuba luphawu oluqhubekayo olubonisa nakuphi na ukuvulwa kwevalvu, okanye lunokuqwalaselwa njengesenzo esiguqukileyo sendawo yokubeka ivalvu.

Iswitshi yokuHamba (Isixhobo seNgxelo yeNdawo):

Umtshintshi wokuhamba ubonisa iindawo ezimbini ezigqithisileyo zevalve kwaye ngaxeshanye uthumela isignali yesalathisi. Igumbi lokulawula linokugqiba i-valve kwi-off-off status ngokusekelwe kulo mqondiso kwaye uthathe amanyathelo ahambelanayo.
