Ivalve yombane ukufakwa komlawuli kunye nohlengahlengiso! Umahluko phakathi kwevalve yombane kunye nevalve yepneumatic

Ufakelo kunye nohlengahlengiso lwesilawuli sevalvu yombane:

1. Faka kwaye uyilungise ngokwemodeli ekhethiweyo kunye neenkcukacha. Itheminali ephantsi kwiphaneli yangasemva kufuneka isekelwe ngokuthembekileyo.

2. Inombolo yomdwebo wesekethe yomlawuli kunye nesixhobo sombane siyafana. Qhagamshela isilawuli kunye nesixhobo sombane ngenombolo yetheminali efanayo ngentambo. Xa isilawuli se-valve yombane sisetyenziselwa inkqubo yokulawula ngokuzenzekelayo, ii-terminals 12, 13 kunye ne-14 zisetyenziselwa ukuvula ngokuzenzekelayo nokuvala i-terminals input terminals yeempawu ezihambelanayo.

3. Cinezela iqhosha lamandla, kwaye isalathisi samandla siya kukhanya. Umtshini wolawulo olukude kwisiza uya kukhomba kwi-remote control, kwaye isalathisi sokulawula kude siya kukhanya.

4, sebenzisa ivili lesandla ukuvula ivalve ukuya kwi-50% yokuvula, cinezela ivalve evulekileyo okanye uvale isitshixo sevalve, khangela ukuba ukujikeleza kwevalve kwaye ucinezele isitshixo siyahambelana, njengokungahambelani ngokukhawuleza cinezela isitshixo sokuphumla, ukucima unikezelo lombane lwezigaba ezithathu, buyisela naziphi na izigaba ezibini zobonelelo lombane lwezigaba ezithathu.

5. Cinezela iqhosha levalve evulekileyo, xa ivalve ivulwe ngokupheleleyo endaweni, isalathisi evulekileyo kwiphaneli yangaphambili iya kukhanyisa; Cinezela iqhosha levalve yokuvala, xa i-valve ivalwe ngokupheleleyo endaweni, isalathisi esisondeleyo kwiphaneli yangaphambili iya kukhanya; Xa i-valve kwinkqubo yokuvula okanye yokuvala idinga ukuphumla, cofa iqhosha lokuphumla, i-valve iphumle. Iitheminali ezimfutshane zokudibanisa i-4 kunye ne-7, ukukhanya kwengozi kwipaneli yangaphambili.

6. Xa i-valve isendaweni evulekile ngokupheleleyo, lungisa i-potentiometer kwipaneli yangaphambili ukwenza imitha yokuvula ibonise i-100%.

I-7, indawo yokutshintsha i-remote control point kwisiza, ukukhanya kwesalathisi sesayithi, ii-terminals zesiphaluka ezimfutshane ze-12 kunye ne-13, i-valve kunye ne-open to run, kwi-point state; Isiphaluka esifutshane No. 12 kunye neNombolo ye-14 ii-terminals, i-valve yokuvala ukuba iqhube, kwi-point state.

8. Fuse 520, 1A kwiphaneli yangasemva.

Umahluko phakathi kwevalve yombane kunye nevalve yepneumatic

Umahluko phakathi kwevalve yombane kunye nevalve yepneumatic:

I-1, umgama wesenzo sevalve yepneumatic mkhulu kunevalve yombane, isantya sokutshintsha ivalve yepneumatic inokulungiswa, ulwakhiwo olulula, ukulugcina lula, inkqubo yesenzo ngenxa yeempawu zesithinteli segesi ngokwayo, akulula ukuba yonakaliswe. by jamming, kodwa kufuneka abe nomthombo womoya, kwaye inkqubo yayo yokulawula intsonkothe ​​ngakumbi kunevalve yombane. Impendulo yevalve ye-pneumatic ikhawuleza, ikhuselekile kwaye ithembekile, iifektri ezininzi ezineemfuno zolawulo eziphezulu zenzelwe izinto zokulawula isixhobo somoya zisete isikhululo somoya esicinezelekileyo. Umthombo wamandla we-actuator yevalve yepneumatic ngumthombo womoya, kwaye umthombo womoya uvela kwicompressor yomoya. Isiginali yokulawula i-elektroniki iguqulwa ibe ngumqondiso wolawulo lwe-pneumatic yi-positioner, kwaye i-actuator ye-pneumatic iqhutyelwa ukulungisa indawo yevalve.

I-2, umthombo wamandla we-valve ye-actuator yombane, ukuba ibhodi yesekethe okanye i-motor fault ikhawuleza ngokukhawuleza, ngoko ke isetyenziswa ngokubanzi kwiimfuno zokusingqongileyo aziphakamisi kwaye akukho bungozi ngexesha le-actuator ye-pneumatic kunye ne-actuator yombane yokudibanisa umsebenzi wokuthelekisa, i-pneumatic. isantya sokuphendula i-actuator sikhawuleza, sinokufaneleka ngakumbi kwisicelo kwiimeko zokulawula, Ngoko ke, abavelisi beevalvu ezilawulayo bonke bavelisa i-actuator pneumatic kunye nokuxhasa.

3. Isantya sokuphendula esilawulayo se-activator yombane asikhawulezi ngokwaneleyo, kwaye i-actuator ye-pneumatic kwivalve yokulawula ingaphezulu kwe-actuator yombane.

I-4, umehluko obalulekileyo phakathi kwe-valve yombane kunye ne-valve ye-pneumatic kukusetyenziswa kwezixhobo ezahlukeneyo zokuqhuba, oko kukuthi, i-actuator, kunye ne-valve yokulawula ngokwayo akukho mahluko. Ukusebenzisana kunye actuators ezahlukeneyo ikakhulu iimfuno iimeko zokusebenza, ezifana ishishini imichiza kunye nezinye iziganeko uqhushumbo, ukusetyenziswa iivalvu womoya, ngenxa yeemfuno eziphakamileyo zokhuseleko, kwaye ixabiso liphantsi, kunye locator ekrelekrele inokuba ebhasini. , indlela yokulawula ilula.
