Ma valve mkati mwa kutayikira njira? Zodzitetezera pakugwira ntchito kwa valve? Zofunikira pakupenta ma valve ndi kulemba chizindikiro

1, dziwani njira yodutsira mkati valavu itatsekedwa kwa maola 4-6, gwiritsani ntchito thermometer ya infuraredi kuti muyeze tsinde (pafupi ndi valavu) kapena 150mm kumunsi kwa kutentha kwachitsulo cha valve, monga wamkulu kuposa 70 ℃, amadziwika kuti "internal leakage". Njirayi imagwira ntchito pama valve ambiri otuluka mkati. Koma m’ntchito yeniyeniyo, tinakumana ndi zochitika zapadera zotsatirazi1) chifukwa cha kuyika kwa payipi, pali ma valve ena asanayambe komanso pambuyo pa kusokonezeka kwa nthunzi yotentha, monga kulumikizidwa ndi kuthamanga kwa payipi, kukhetsa kwa chubu cha jellyfish.
Choyamba, muyezo wa kutayikira kwa valve
1, dziwani njira yodutsira ma valve
Pambuyo pa maola 4-6 atseka ma valve, gwiritsani ntchito thermometer ya infrared kuti muyese kutentha kwachitsulo pa tsinde (pafupi ndi thupi) kapena 150mm kumunsi kwa thupi, ngati kupitirira 70 ° C, kumatengedwa ngati "kutuluka kwamkati". Njirayi imagwira ntchito pama valve ambiri otuluka mkati.
Komabe, mu ntchito yathu yothandiza, tinakumana ndi zochitika zapadera izi:
(1) Chifukwa cha malo oyika payipi, pali ma valve ena asanayambe komanso pambuyo pa kusokonezeka kwa kutentha kwa kutentha, monga kulumikizidwa ndi kukhetsa kwapaipi, msampha wa chitoliro cha jellyfish kapena chitseko chokhetsa, mavavuwa ngakhale atayikira kwambiri, valavu. kutentha kwa tsinde kudzakhala kupitirira 70 ℃.
(2) Kumbali ndi mbali lowetsani chitseko cha msampha kapena chitseko cha msampha ndi chitoliro cha jellyfish. Malo a valavu akakhala pafupi ndi chitoliro chachikulu, bola ngati valavu iliyonse yanthambi mupaipi ikutha, kutentha kwa ma valve ena kumakwera kupitirira 70 ℃, monga valavu ya boiler, kukhetsa kwa nthunzi, ndi zina zotero. Chifukwa chake, KUSINTHA KWA KUTHA KWA NTCHITO M'MAVAVU AWA KUKHALA KUKHALA NDI NJIRA ZINA, MONGA KUYENZA KUCHULUKA KWA Khoma la Khoma kapena PRIMARY KHOMO KUTENGA NTCHITO KUTI KUDZIWA KUTHA KWA NTCHITO.
Chachiwiri, ntchito ya valve ndi yofunika kwambiri
1. Pazitseko zamabuku a madzi otsekemera a madzi otentha, ayenera kuwonjezeredwanso theka la ola pambuyo pomaliza ntchito kuti athetse kusiyana kwa valve chifukwa cha kuwonjezereka kwa kutentha ndi kuzizira kwa kutentha.
2. Kwa chitoliro cha kutentha ndi chitseko chimodzi kapena ziwiri, ndondomeko ya ntchito ya valve ndi motere: tsegulani chitseko kamodzi musanatsegule chitseko kawiri; Mukatseka, muyenera choyamba kutseka chitseko kawiri ndikutsekanso chitseko.
3, chifukwa cha ntchito ya valve pachipata, ikhoza kutsekedwa kwathunthu kapena kutsegulidwa kwathunthu, musalole theka lotseguka theka lotsekedwa, kuti muchepetse kuwonongeka kwa valve.
Chachitatu, kasamalidwe ka ma valve ndi nkhani zofunika kuziganizira
Gawo 1, isanayambe kuyesedwa kwa magetsi, pneumatic valve test, test test test, iyenera kukhala katswiri wowunika momwe ma valve ndi kayendedwe ka damper akuyendera, yang'anani ndodo yolumikizira ndipo pini isakhale yotayirira, kugwada ndi kugwa, yang'anani mayendedwe a kutsegulidwa kwa DCS ndipo in situ iyenera kukhala yofanana, pali khomo lamagetsi loyimitsa lapakati kuti muyese kuyimitsa kwapakati ndikwachilendo. Sinthani njira yosinthira khomo ndi yolondola, yosinthika, yokhala ndi chipika cholumikizira ku mayeso oyenera olumikizirana akatswiri, chipangizo chosinthira ma pneumatic chikuyenera kukhala chosinthika, palibe kutayikira komanso zochitika zachilendo, mayesowo amayenera kuyimitsa mayeso akakhala achilendo, dziwitsani nthawi yake ogwira ntchito yosamalira kuti athane ndi vutoli. ndi.
Unit 2, nthawi iliyonse mukayamba, iyenera kukhala yogwirizana ndi zomwe zikugwiritsidwa ntchito, chipata chamadzi ShuFang chiyenera kuyang'ana kutsekedwa ndi lamulo, madzi a ShuFang amazimitsidwa (maola 10) pambuyo pa maola 6, pambuyo pa chipata cha madzi. chizindikiro cha kutentha kwa hydrophobic, chiyenera kukhazikitsidwa pa chitoliro cha valve pambuyo pofufuza ndikuweruza ngati kutayikira kwa valve, kutentha kusonyeza kuti palibe kutentha komwe kumasonyeza kuti ndi woonda pambuyo pa watergate, thermometer ya infuraredi imagwiritsidwa ntchito kuyeza kutentha kwa kutsogolo ndi kumbuyo kwa makoma a chitoliro. valavu kapena kumva kuti muwone ngati valavu ikutha. Monga kutayikira kwamagetsi kapena pneumatic valve, kuyenera kutsekedwa khomo lamagetsi la hydrophobic kapena chitseko cha pneumatic chitseko chodzipatula, chitseko chamagetsi cha hydrophobic, chitseko cha pneumatic popanda chitseko chodzipatula, monga kutayikira, chiyenera kugwedezeka kutseka chitseko chamagetsi, ndikusowa ndi kukhudzana. chithandizo chamankhwala. Monga Buku khomo kutayikira, ndi akusowa ndi kukhudzana yokonza mankhwala.
3, nthawi iliyonse isanayambe kutsekedwa, zowonongeka za valve (kutayikira) ziyenera kuyang'aniridwa, valve yowonongeka iyenera kukwera ndikudziwitsa dipatimenti yoyenera yokonza.
4. Potsegula ndi kuyimitsa njira kapena ndi njira yothira madzi, chitseko cha madzi chikatsegulidwa, fufuzani ngati pali kutentha pambuyo pa valve kapena throttle hole (msampha), kuti muwonetsetse kuti ikhoza kugwira ntchito ngalande (kutulutsa) madzi, kuteteza dzimbiri chifukwa cha kutentha kwa chitoliro cha madzi chifukwa cha kutsekeka kwa valavu kapena payipi kapena throttle hole (msampha).
KUPITA KWA VALVU NDI KUSINTHA ZINTHU KUTI KUDZIWA KWA VALVU KUKHALA PANTHAWI YOPANDA WOSACHITA PA THUPI LA VALVI NDI BONNET, NDIPO CHIZINDIKIRO CHODINDIKIRA PANKHOMBO CHIDZAPIKIDWA PA ZOPANDA ZOKHUDZA ZOTHANDIZA, NTCHITO YOPITA, NDIPONSO ZOPANDA. MONGA ZAKULAMBIRA PAGOLI PAMSIMU. Mtundu wa utoto wamakina opatsirana umatchulidwa motere: chipangizo chamagetsi, mtundu wamba wopaka utoto wapakati; Atatu mwa amodzi (akunja, osaphulika, odana ndi dzimbiri) mtundu wopaka utoto wabuluu; Pneumatic, hydraulic, gear transmission ndi njira ina yopatsira yomwe ili ndi mtundu wa chinthu cha valve.
1. Kuzindikiritsa zigawo za valve
Pa chigoba cha valve ya valve, pali mzere wopingasa wokhala ndi muvi. Manambala omwe ali pamwamba pa mzere wopingasa amasonyeza kuchuluka kwa kuthamanga kwadzina, ndipo ena amasonyeza chizindikiro cha kutentha ndi kuthamanga kwa ntchito. Mwachitsanzo, PNl0 ndi PT510 amagwiritsidwa ntchito pansi pa magawo opangira 10MPa ndi 510 ℃. Nambala yomwe ili pansi pa mzere wopingasa imasonyeza m'mimba mwake mwadzina la chitoliro cholumikizira.
→ imasonyeza kuti valavu ndi yowongoka, yolowera pakati ndi njira yotuluka, mu mzere wapakati womwewo kapena wofanana.
Chrysene> imasonyeza kuti gawo la valve ndi mtundu wa angle-angle, sing'anga imachita pa gawo lotseka.
Zimasonyeza kuti valavu ili ndi njira zitatu ndipo sing'anga ili ndi njira zingapo zoyendetsera.
