Mububambe bwakupanga mapaipi, kusala kabotu kwamavalvu aamagesi nchintu chimwi chisinizya kuti zibelesyegwe. Kuti vvavuvu lyamagesi libelesedwe tiilyasalwa kabotu, talikonzyi buyo kunyonganya kubelesya, pele alimwi liyooleta mapenzi naa kusweekelwa kupati, aboobo, kusala kabotu vvavuvu zyamagesi mubupange bwakupanga mapaipi.
Busena bwakubelekela bwavalvu yamagesi
Mukuyungizya kukubikkila maanu kuzyeelelo zyamupaipi, kubikkila maanu kapati kweelede kuchitwa kubukkale bwabusena bwakubeleka kwawo, nkaambo chintu chamagesi muvalvu yamagesi nchibelesyo chamagesi, mpawo bukkale bwacho bwakubeleka bulajatikizyigwa kapati abusena bwakubelekela. Mbukubede, busena bwakubelekela bwavalvu yamagesi mbuboobu:
1. Kubikka mukati naa kubelesya anze antoomwe anzila zyakukwabilila;
2. Kubikka anze anze, amuwo, musenga, mvwula amume, mumuni wazuba akunyonyooka kumwi;
3. Chili abusena bukonzya kuyaka naakuti bukonzya kupwasuka muya naakuti bulongo;
4. Busena bujisi mvwula, busena butakwe maanzi;
5. Ikupya kwamupaipi kuli atala kusika ku 480°C naa kwiinda waawo;
6. Kupya kwabusena kuli munsi a -20°C;
7. Nchuubauba kuzabulwa mumaanzi naakuti kubbizyigwa mumaanzi;
8. Busena bujisi zintu zipa nguzu zya radioactive (maanda aapanga nguzu zya nyukiliya alimwi azibelesyo zyakusunka zintu zijisi nguzu zya radioactive);
9. Busena bwabwaato naakuti busena bwakukkala (amunyo wakusansaila, nkumba, akutontola);
10. Ziindi zyakuzungaana kupati;
11. Ziindi zikonzya kupya mulilo;
Kumavalvu aamagesi mumasena aambwa atala aawa, bupange, zibelesyo anzila zyakukwabilila zibelesyo zyamagesi ziliindene. Aboobo, chibelesyo chamagesi cha valve cheelede kusalwa kweendelana abusena bwakubelekela bwaambwa atala aawa.
Ziyandikana zyakubelesya magesimavalvu
Kweelana aziyandikana zyakweendelezya, ku vvalavu yamagesi, mulimo wakweendelezya ulamanizyigwa achibelesyo chamagesi. Makanze aakubelesya mavalvu aamagesi ngakuti kube kweendelezya magesi kutabelesyegwi amaanza naa kkompyuta mukujalula, kujala akubamba mavalvu. Zibelesyo zyamagesi zyamazubaano tazibelesyegwi buyo kukwabilila bantu. Akaambo kakusiyanasiyana kupati kwakubeleka abubotu bwazintu zizwa kuli basikupanga baindene, kusala zibelesyo zyamagesi akusala mavalvu zilayandika kapati mumulimo ooyu.
Kweendelezya magesi kwamagesimavalvu
Akaambo kakuzumanana kuyaambele kwazyeelelo zyakubelesya minchina yamakkampani, kulubazu lumwi, kubelesya mavwili aamagesi kuyaambele, mpawo kulubazu lumwi, zyeelelo zyakweendelezya mavwili aamagesi zilikuyaambele akukatazya. Aboobo, bupange bwamavalvu aamagesi mumakani aakweendelezya magesi abwalo bulabambululwa chiindi choonse. Kakuli kuyaambele kwasayaansi atekkinoloji akuzyibwa akubelesya makkompyuta, nzila zipya zyakweendelezya magesi ziyoozumanana kulibonya. Kuti kube kweendelezya koonse kwamagesivvalavu, kubikkila maanu kweelede kuchitwa kukusala nzila yakulela vvalavu yamagesi. Mbuli chitondeezyo, kweendelanya aziyandikana zyapulojekiti, naa kubelesya nzila yakweendelezya akati, naa nzila yomwe, naa kubelesya zibelesyo zimwi, kweendelezya pulogilamu naa kubelesya kweendelezya pulogilamu yakkompyuta, azimwi, njiisyo yakweendelezya iliindene. Chikozyano chasikupanga zibelesyo zyamagesi zyavalvu zipa buyo njiisyo zyakweendelezya magesi, aboobo dipatimenti iilanganya zyakubelesya yeelede kuchita chitondeezyo chabusongo abasikupanga zibelesyo zyamagesi akusalazya zyeelelo zyabusongo. Mukuyungizya, nusala vvalavu yamagesi, weelede kuyeeya kuti naa ulakonzya kuula imwi ntalisyo yamagesi. Nkaambo mubwini, mweendelezi weelede kuulwa alikke. Muzyiindi zyiingi, notubelesya chintu chomwe, nkuko kuyandika kuula chibelesyo, nkaambo nchuubauba mpawo nchuuba kuula chibelesyo kwiinda kuchibamba akupanga amuntu uubelesya. Eelyo bweendelezi bwamagesi nobutakonzyi kuzuzikizya ziyandikana zyakupanga, sikupanga weelede kwaambwa kuti achinche naakuti achite bupya.
Chibelesyo cha magesi cha valve nchibelesyo chikonzya kuchita pulogilamu ya valve, zyeendelezya alikke akweendelezya kule*, mpawo kweenda kwacho kulakonzya kweendelezyegwa amweelwe wa stroke, torque naakuti axial thrust. Mbwaanga bube bwakubeleka akubelesya kwa valve actuator kuyeeme amusyobo wa valve, nzila yakubeleka yachibelesyo, antoomwe abusena bwa valve aamupayipi naakuti zibelesyo, kusala kabotu kwa valve actuator kulayandika kapati kutegwa kutabi kuvwundauka (nguzu zyakubeleka zilisumpukide kwiinda nguzu zyakweendelezya). Muchiindi choonse, ntalisyo yakusala kabotu zibelesyo zyamagesi zili boobu:
Nguzu zyakubelekaNguzu zyakubeleka ninzila mpati yakusala chibelesyo chamagesi, mpawo nguzu zyakuzwa zyachibelesyo chamagesi zyeelede kuba ziindi zili 1.2~1.5 zya nguzu zyakubeleka zya valve.
Kuli minchina mipati yobile iibelesya chibelesyo cha magesi cha thrust valve: yomwe tiijisi thrust disc mpawo ilagwisya nguzu zyamagesi; Chimwi nchakubamba bbazu lyakusunka, mpawo nguzu zyakuzwa zilasandulwa kuba mpuwo yakuzwa kwiinda muchikozyano chakusunka.
Mweelwe wakuzungaana kwamugoti wakuzwa wachibelesyo chamagesi ulaswaangene abwaamba bwamuvuvu, kulampa kwachisiko antoomwe amweelwe wantambo, eezyo zyeelede kubalwa kweendelanya a M=H/ZS (M mweelwe woonse wakuzungaana ooko chibelesyo chamagesi nkocheelede kuzuzikizya, H mbulamfwu bwakujula kwavalvu, S mbupati bwantambo, Z mutwe wantambo Z chivvalavuchisiko).
Kuti bupati bwachisiko buzumizigwa achibelesyo chamagesi tabukonzyi kwiinda muchisiko cha valve iijisi, tachikonzyi kusanganyigwa kuba valve yamagesi. Aboobo, bupati bwamukati bwachikobela chakuzwa cha actuator bweelede kuba bupati kwiinda bupati bwaanze bwa chisiko cha valve yamusamu uujalukide. Ku valve ya musako uusiya mu partal rotary valve a multi-turn valve, nikuba kuti penzi lyakuinda lya valve stem diameter talibikkilwi maanu, diameter ya valve stem abwaamba bwa keyway azyalo zyeelede kulanga-langwa loko notusala, kuchitila kuti zibeleke kabotu nikwakamana kubunganizigwa.
Kuti kujalula akujala kwakufwambaana kwa vvalavu yakuzwa kwakufwambaana, nchuubauba kupanga nkomo yamaanzi. Aboobo, kufwambaana kwakujalula akujala kweelede kusalwa kweendelanya abukkale bwakubelesya bwiindene.
Ma valve actuators alijisi ziyandika zyawo zilibedelede, nkokuti ayelede kukonzya kupandulula torque naa nguzu zya axial. Chiindi chiingivvalavuzibelesyo zibelesya zijatikizyo zilesya kuzungaana. Aawo bupati bwachibelesyo chamagesi nibwajanwa, inguzu zyacho zyakweendelezya azyalo zilajanwa. Kanjaanji kweenda muchiindi cheelede, injini taikonzyi kuzula pe. Nokuba boobo, kuti zintu zitobela zyachitika, zilakonzya kuleta kunyamuna zintu zyiingi: chakusanguna, nguzu zyamagesi zili munsi, mpawo nguzu ziyandika tazikonzyi kujanwa pe, aboobo injini ilaleka kuzungaana; cabili nchakulubizya kuchincha nzila yakulesya nguzu zyakuzungaanya kuti ibe mpati kwiinda nguzu zyakulesyela, eezi zipa kuti kube nguzu zyiingi loko akuimika injini; chatatu nkubelesya kwachiindi chifwiifwi, mpawo kupya kujanika kwiinda mweelwe wakupya uuzumizyidwe wa injini; Chachina, nzila yakulesya nguzu zyakuzungaanya yaalilwa nkaambo kamwi, eecho chipa kuti nguzu zyakuzungaana zibe mpati loko; Cha musanu, kupya kwabusena kulisumpukide loko, ooko kuchesya nguzu zyakupya kwa injini.
Muchiindi, nzila yakukwabilila injini yakali yakubelesya ma fuse, ma overcurrent relays, thermal relays, thermostats, azimwi, pesi nzila eezyi zilijisi bubotu abubi bwazyo. Kunyina nzila iisyomeka yakukwabilila zibelesyo zijisi mikuli iindene-indene mbuli zibelesyo zyamagesi. Aboobo, misanganya yiindene-indene yeelede kubelesegwa, eeyo iikonzya kwaambwa muzibeela zyobile: yomwe njakubeteka kuyungizigwa naa kucheya kwanguzu zyakunjizya mumootokala; Cabili nkubeteka bukkale bwakupya kwa injini. Munzila iili yoonse, kufumbwa nzila ilabikkila maanu kuchiindi chakapegwa chakupya kwa injini.
Kanjaanji, nzila yakusaanguna yakukwabilila kuzwa kuzintu zyiingi njakuti: kukwabilila zintu zyiingi mukuzumanana kubeleka naakuti kweenda kwa injini, kubelesya thermostat; Mukukwabilila injini, thermal relay yakabelesegwa; Kuntenda zyakufwiinsya, ma fuse naakuti ma relay aayinda magesi alabelesyegwa.
