I-valve yokulawula umoya ibhekisela ku-valve yokulawula umoya, ethatha umthombo womoya njengamandla, isilinda njenge-actuator, isignali engu-4-20mA njengesignali yokushayela, futhi ishayela i-valve ngokusebenzisa izesekeli ezifana ne-valve positioner kagesi, i-converter, i-solenoid valve kanye ne-valve yokubamba, ukuze yenze i-valve yenza i-valve elinganayo, inqubo yokugeleza noma enye i-parameter, i-parameter egelezayo. ophakathi kwamapayipi angalungiswa ngendlela elinganayo.
I-valve yokulawula umoya inezinzuzo zokulawula okulula, ukuphendula okusheshayo nokuphepha kwangaphakathi, futhi uma isetshenziswa ezenzakalweni ezivuthayo neziqhumane, ayidingi ukuthatha izinyathelo ezengeziwe zokuvikela ukuqhuma.
Isimiso sokusebenza se-valve yokulawula umoya we-pneumatic:
I-valve yokulawula umoya ngokuvamile yakhiwa i-actuator ye-pneumatic kanye nokuxhumana kwe-valve elawulayo, ukufakwa kanye nokugunyazwa. I-actuator yomoya ingahlukaniswa ngezinhlobo ezimbili: uhlobo lwesenzo esisodwa kanye nohlobo lwesenzo esikabili. Kukhona intwasahlobo ebuyayo ku-actuator yesenzo esisodwa, kodwa ayikho intwasahlobo ebuyayo ku-actuator yesenzo esikabili. I-actuator eyodwa ebambayo ingabuyela ngokuzenzakalelayo esimweni sokuvula noma sokuvala esisethwe yi-valve lapho umthombo womoya ulahlekile noma i-valve ihluleka.
Imodi yokusebenza ye-valve yokulawula umoya:
Ukuvuleka komoya (ngokuvamile kuvalwe) yilapho ukucindezela komoya ekhanda le-membrane kwanda, i-valve iqhubekela phambili ekuvulekeni okwandayo. Lapho ukucindezela komoya okokufaka kufinyelelwa, i-valve isesimweni esivulekile ngokugcwele. Ngokulandelayo, lapho ukucindezela komoya kuncipha, i-valve ihamba ngendlela evaliwe, futhi lapho kungekho moya ongenayo, i-valve ivalwe ngokugcwele. Ngokuvamile, sibiza i-valve elawula ukuvuleka komoya njenge-valve evaliwe.
Isiqondiso sesenzo sohlobo lokuvala komoya (uhlobo oluvame ukuvuleka) luphambene ncamashi nohlobo lokuvula umoya. Lapho umfutho womoya ukhuphuka, i-valve ihamba ngendlela evaliwe; lapho ukucindezela komoya kuncipha noma cha, i-valve izovuleka noma ivuleke ngokugcwele. Ngokuvamile, sibiza i-valve yokulawula uhlobo lokuvala igesi njenge-valv evulekile yephutha
Umehluko nokukhetha phakathi kwe-valve yebhola yesikhulumi esiphezulu kanye ne-valve yebhola evamile
I-valve yebhola yesikhulumi esiphezulu, okuthiwa i-valve yebhola yesikhulumi esiphezulu, yamukela i-05211 yokukhiqiza indinganiso, iphonsa i-flange yesikwele noma eyindilinga kanye ne-valve yebhola njengomzimba, futhi ubuso bokugcina besiteji buphakeme kunomkhawulo wangaphandle we-flange emikhawulweni yomibili, engagcini nje kuphela ekufakweni kwe-actuator pneumatic, i-actuator kagesi kanye ne-actuator enkulu kanye namanye amadivaysi okuthuthukisa i-valve. i-actuator, futhi ukubukeka kuhle kakhulu futhi kucwengekile.
I-valve yebhola yesikhulumi esiphezulu iwumkhiqizo wokuziphendukela kwemvelo wevalvu yebhola yebakaki evamile evamile. Umehluko phakathi kwe-valve yebhola yesikhulumi esiphezulu kanye ne-valve yebhola evamile ukuthi ingaxhunywa ngokuqondile ne-actuator yokushayela ngaphandle kokwengeza ubakaki wokuxhuma, kuyilapho i-valve yebhola evamile ingafakwa kuphela ne-actuator ngemva kokufakwa kukabakaki. Ngaphezu kokuqeda ukufakwa kwe-bracket eyengeziwe, ngoba ifakwe ngokuqondile epulatifomu, ukuzinza phakathi kwe-actuator ne-valve yebhola kuthuthukiswa kakhulu.
Inzuzo ye-valve yebhola yesikhulumi esiphezulu ukuthi ingafaka ngokuqondile i-actuator ye-pneumatic noma kagesi endaweni yayo, kuyilapho i-valve yebhola evamile idinga ukuxhumeka kwe-valve eyengeziwe, okungase kuthinte i-valve esetshenziswayo ngenxa yobakaki ovulekile noma imvume yokuxhuma ngokweqile. I-valve yebhola yesikhulumi esiphezulu ngeke ibe nale nkinga, futhi ukusebenza kwayo kuzinzile kakhulu ngesikhathi sokusebenza.
Ekukhetheni i-valve yebhola yesikhulumi esiphezulu kanye ne-valve evamile yebhola, isakhiwo sangaphakathi se-valve ye-billiard yesikhulumi esiphezulu kusengumgomo wokuvula nokuvala, okuhambisana ne-valve evamile yebhola. Ngaphezu kwezinzuzo ezishiwo ngenhla, lapho izinga lokushisa eliphakathi nendawo liphakeme ngokuqhathaniswa, ubakaki wokuxhuma kufanele usetshenziselwe ukuvikela ukusetshenziswa okuvamile kwe-actuator nokuvimbela i-actuator ukuthi ingakwazi ukusebenzisa ngenxa yokudlulisa ukushisa okuphakathi.
