Umoya olawula ivelufa ibhekisa kwivelufa yomoya womoya, othatha umthombo womoya njengamandla, isilinda njengesixhobo, umqondiso we-4-20mA njengophawu lokuqhuba, kwaye uqhuba ivalve ngokusebenzisa izinto ezinje ngombane wevalufa yombane , Isiguquli, iveluva yentsimbi kunye nevalve yokubamba, ukwenzela ukuba ivelufa yenze isenzo sokumisela kunye neempawu zokuhamba ngokulinganayo okanye ngokulinganayo, ke, ukuhamba, uxinzelelo, ubushushu kunye nezinye iiparameter zenkqubo yombhobho wolungelelwaniso zinokuhlengahlengiswa ngendlela elinganayo.
Umoya womoya ivelufa inezibonelelo zolawulo olulula, impendulo ekhawulezileyo kunye nokhuseleko lwangaphakathi, kwaye xa isetyenziswa kwizihlandlo ezinokutsha neziqhumayo, akufuneki ukuba ithathe amanyathelo ongezelelweyo okuqhushumba.
Umgaqo wokusebenza wevalufa yokulawula umoya:
Ivalufa yomoya womoya ihlala iqulathe i-ptuatic actuator kunye nokulawula uxhulumaniso lwevalve, ukufakwa kunye nokugunyaziswa. I-actuator yomoya inokwahlulahlulwa ibe ziindidi ezimbini: uhlobo olunye lwentshukumo kunye nohlobo lwesenzo esiphindiweyo. Kukho intwasahlobo ebuyayo kwisenzo esinye se-actuator, kodwa akukho kubuya kwentwasahlobo kwi-actuator yesenzo esiphindwe kabini. I-actuator ebambeleyo inokubuyela ngokuzenzekelayo kwindawo yokuvula okanye yokuvala ebekwe yivalve xa umthombo womoya ulahlekile okanye ivelufa ingaphumeleli.
Imo yentshukumo yomoya wevalufa yomoya:
Ukuvulwa komoya (ngesiqhelo kuvaliwe) kuxa uxinzelelo lomoya kwintloko ye-membrane inyuka, ivelufa iya kwicala elonyukayo lokuvula. Xa kufakwa uxinzelelo lomoya, ivelufa ikwimeko evulekileyo ngokupheleleyo. Emva koko, xa uxinzelelo lomoya luyehla, ivelufa iya kwicala elivaliweyo, kwaye xa kungekho moya ungenayo, ivelufa ivaliwe ngokupheleleyo. Ngokubanzi, sibiza ukuvulwa komoya kwivelufa yempazamo njengevalvu evaliweyo.
Isalathiso sentsingiselo yohlobo lokuvala lomoya (uhlobo oluvulekileyo oluqhelekileyo) luchasene ngqo nolo lohlobo lokuvula umoya. Xa uxinzelelo lomoya lonyuka, ivelufa iya kwicala elivaliweyo; xa uxinzelelo lomoya luyancipha okanye alwenzi, ivalve iya kuvula okanye ivule ngokupheleleyo. Ngokubanzi, sibiza uhlobo lwegesi evaliweyo elawula ivelufa njengevali evulekileyo
Umahluko kunye nokukhetha phakathi kweqonga eliphezulu levalve yebhola kunye nevalve yebhola eqhelekileyo
Iplatifti yebhola yeqonga ephezulu, ekuthiwa yivelve yebhola ephezulu, yamkela umgangatho we-is05211, iphosa isikwere okanye isangqa esisangqa kunye nevalve yebhola njengomzimba, kwaye isiphelo seqonga liphezulu kunomphetho wangaphandle weflange kuzo zombini iphela, nto leyo efanelekileyo kuphela ukufakelwa actuator womoya, actuator yombane kunye nezinye izixhobo actuator, kodwa kwakhona kuphucula kakhulu uzinzo phakathi ivelufa kunye actuator, kwaye imbonakalo intle kakhulu kwaye esulungekisiweyo.
Ivelufa yebhola yebhola ephezulu yimveliso yendalo yevalufa yebhola yesiqhelo yebhanki. Umahluko phakathi kwevalve yebhola yeqonga ephezulu kunye nevalve yesiqhelo yebhola kukuba inokudityaniswa ngokuthe ngqo ne-actuator yokuqhuba ngaphandle kokongeza isibiyeli esiqhagamshelekayo, ngelixa ivalve yebhola yesiqhelo inokufakwa kuphela ne-actuator emva kokuba isibiyeli sifakiwe. Ukongeza ekupheliseni ukufakelwa kwesibiyeli esongezelelweyo, kuba ifakwe ngokuthe ngqo kwiqonga, uzinzo phakathi kwe-actuator kunye nevalve yebhola iphuculwe kakhulu.
Uncedo lwebhola yebhola yebhola ephezulu kukuba inokufaka ngokuthe ngqo i-pneumatic okanye i-actuator yombane kwiqonga layo, ngelixa ivelufa yebhola yesiqhelo ifuna uqhagamshelo lwevalve eyongezelelweyo, enokuthi ichaphazele ivalve esetyenziswayo ngenxa yesibiyeli esivulekileyo okanye imvume yokuhlangana okungaphezulu. Iplatifti yebhola yebhola ephezulu ayizukuba nayo le ngxaki, kwaye ukusebenza kwayo kuzinzile kakhulu ngexesha lokusebenza.
Kukhetho lweqonga lebhola yentsimbi ephezulu kunye nevalve yesiqhelo yebhola, Ulwakhiwo lwangaphakathi lwebhola yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi yebhodi ibisengumgaqo wokuvula nokuvala, ohambelana nevalve yesiqhelo yebhola. Ukongeza kwizibonelelo ezikhankanywe apha ngasentla, xa ubushushu obuphakathi buphezulu kakhulu, isibiyeli esiqhagamshelekayo kufuneka sisetyenziselwe ukukhusela ukusetyenziswa kwesiqhelo kwesixhobo kunye nokuthintela i-actuator ekubeni ingabinakho ukuyisebenzisa ngenxa yokuhambisa ubushushu obuphakathi.
