Isimiso sokusebenza se-valve elawula umoya womoya

I-valve elawula i-pneumatic ibhekisela ku-valve yokulawula umoya, ethatha umthombo womoya njengamandla, isilinda njenge-actuator, isignali ye-4-20mA njengesiginali yokushayela, futhi ishayela i-valve ngezinsiza ezifana ne-valve valve positioner , i-converter, i-valve ye-solenoid ne-valve yokubamba, ukuze kwenziwe i-valve isenzo sokulawula ngezimpawu zokugeleza okuqondile noma okulinganayo, Ngakho-ke, ukugeleza, ingcindezi, izinga lokushisa kanye neminye imingcele yenqubo yepayipi eliphakathi ingalungiswa ngendlela elinganayo.

I-valve yokulawula umoya inezinzuzo zokulawula okulula, ukuphendula okusheshayo nokuphepha kwangaphakathi, futhi uma isetshenziswa ezimweni ezivuthayo neziqhumayo, ayidingi ukuthatha ezinye izindlela zokuqhuma.

Isimiso sokusebenza se-valve elawula umoya womoya:
I-valve yokulawula umoya womoya ivame ukwenziwa nge-pneumatic actuator nokulawula ukuxhumana kwe-valve, ukufakwa nokuthunyelwa. I-actuator yomoya ingahlukaniswa ngezinhlobo ezimbili: uhlobo lwesenzo esisodwa nohlobo lwesenzo esiphindwe kabili. Kukhona intwasahlobo ebuyayo ku-actuator yesenzo esisodwa, kepha ayikho intwasahlobo yokubuyisa ku-actuator yesenzo esiphindwe kabili. I-actuator esebenzayo eyodwa ingabuyela ngokuzenzakalela esimweni sokuvula noma sokuvala esethwe yi-valve lapho umthombo womoya ulahlekile noma i-valve yehluleka.

Imodi yesenzo ye-valve elawula umoya womoya:
Ukuvulwa komoya (okuvame ukuvalwa) kulapho ingcindezi yomoya ekhanda le-membrane inyuka, i-valve ihambela ngasendaweni yokuvula okwandayo. Lapho umfutho womoya wokufaka ufinyelelwa, i-valve isesimweni esigcwele esivulekile. Ngokulandelayo, lapho umfutho womoya uncipha, i-valve iya ohlangothini oluvaliwe, futhi lapho kungekho moya okokufaka, i-valve ivalwa ngokuphelele. Ngokuvamile, sibiza i-valve yokulawula ukuvulwa komoya njengephutha i-valve evaliwe.

Ukuqondiswa kwesenzo kohlobo lokuvala umoya (uhlobo oluvame ukuvuleka) kufana ncamashi nalokho kohlobo lokuvulwa komoya. Lapho umfutho womoya unyuka, i-valve iya ohlangothini oluvaliwe; lapho umfutho womoya uncipha noma ungasebenzi, i-valve izovuleka noma ivule ngokuphelele. Ngokuvamile, sibiza uhlobo lokulawula igesi lokulawula igesi njenge-valve evulekile enephutha

Umehluko nokukhethwa phakathi kwepulatifomu yebhola yesikhulumi ephezulu ne-valve yebhola ejwayelekile
Ipulatifomu yebhola yasepulatifomu ephezulu, ebizwa nge-high-ball ball valve, isebenzisa i-is05211 yokukhiqiza ejwayelekile, iphonsa i-flange eyisikwele noma eyindilinga ne-valve yomzimba njengomzimba, futhi ukuphela kobuso besikhulumi kuphakeme kunomphetho wangaphandle we-flange ukuphela, okungahambisani nokufakwa kwe-actuator yomoya kuphela, i-actuator kagesi namanye amadivayisi we-actuator, kepha futhi kuthuthukisa kakhulu ukuzinza phakathi kwe-valve ne-actuator, futhi ukubukeka kuhle kakhulu futhi kucwengekile.

I-high ball ball valve ingumkhiqizo wokuvela we-valve ejwayelekile yebakaki yebhola. Umehluko phakathi kwepulatifomu yebhola yesikhulumi ephezulu ne-valve yebhola ejwayelekile ukuthi ingaxhunyaniswa ngqo ne-actuator yokushayela ngaphandle kokungeza ubakaki wokuxhuma, kuyilapho i-valve yebhola ejwayelekile ingafakwa kuphela ne-actuator ngemuva kokuthi ubakaki ufakiwe. Ngaphezu kokuqeda ukufakwa kubakaki abengeziwe, ngoba kufakwe ngqo epulatifomu, ukuzinza phakathi kwe-actuator ne-valve yebhola kuthuthukiswa kakhulu.

Ubuhle bepulatifomu yebhola yasepulatifomu ephezulu ukuthi ingakwazi ukufaka ngqo i-actuator yomoya noma kagesi epulatifomu yayo, kuyilapho i-valve yebhola ejwayelekile idinga ukuxhumeka okwengeziwe kwe-valve, okungathinta i-valve esetshenziswayo ngenxa yobakaki ovulekile noma imvume yokuhlanganisa okweqile. I-valve yebhola yesikhulumi ephezulu ngeke ibe nale nkinga, futhi ukusebenza kwayo kuzinzile kakhulu ngesikhathi sokusebenza.

Ekukhetheni i-valve yebhola yesikhulumi ephezulu ne-valve ejwayelekile yebhola, ukwakheka kwangaphakathi kwepulatifomu ye-billiard valve kusengumgomo wokuvula nokuvala, okuhambisana ne-valve yebhola ejwayelekile. Ngaphezu kwezinzuzo ezibalulwe ngenhla, lapho izinga lokushisa eliphakathi liphakeme ngokwengeziwe, ubakaki wokuxhuma kufanele usetshenziselwe ukuvikela ukusetshenziswa okujwayelekile kwe-actuator futhi uvimbele i-actuator ukuthi ingakwazi ukusebenzisa ngenxa yokudlulisa okuphakathi kokushisa.
