Ntchito ya valavu ndi zinthu zomwe ziyenera kuganiziridwa posankha wanzeru chowongolera valavu yamagetsi chida chachikulu chogwirira ntchito Kusankhidwa kwa mavavu kumatengera magwiridwe antchito ndi chitetezo ndi kulingalira kwachuma, kufananiza kwathunthu kwa zotsatira zamphamvu. Zotsatira zotsatirazi ziyenera kuperekedwa musanasankhe ma valve: 1, katundu wakuthupi (1) Mkhalidwe wa zinthu a. Mkhalidwe wa zinthu za gasi umaphatikizapo: data yokhudzana ndi katundu, gasi weniweni kapena kusakaniza, kaya pali madontho kapena tinthu tating'onoting'ono, komanso ngati pali zigawo zomwe ziyenera kusungunuka. b. Mkhalidwe wa zinthu zamadzimadzi umaphatikizapo: (1) Zokhudzana ndi katundu wakuthupi, kaya chigawo choyera kapena chosakaniza chili ndi zigawo zosasunthika kapena mpweya wosungunuka (umene ukhoza kupangidwa kuti upangitse kutuluka kwa magawo awiri pamene kuthamanga kutsika), kaya ili ndi zolimba. inaimitsidwa nkhani, ndi kugwirizana, kuzizira mfundo kapena kuthira mfundo ya madzi. (2) Katundu wina; Kuphatikizira dzimbiri, kawopsedwe, kusungunuka kwa zida zamapangidwe a ma valve, ngakhale zitha kuyaka komanso kuphulika. Izi katundu nthawi zina osati zimakhudza zakuthupi, komanso chifukwa wapadera structural zofunika, kapena kufunika kusintha chitoliro kalasi. 2. Ntchito zogwirira ntchito pansi pa kayendetsedwe ka ntchito (1) Malingana ndi kutentha ndi kupanikizika pansi pazikhalidwe zogwirira ntchito, m'pofunikanso kugwirizanitsa zochitika zogwirira ntchito zotsegula ndi kutseka kapena kubadwanso. a. Vavu yotulutsira pampu iyenera kuganizira za kutsekeka kwakukulu kwa mpope. b. Pamene kutentha kwa kubadwanso kwa dongosolo kumakhala kwakukulu kwambiri kuposa kutentha kwabwinoko pamene kupanikizika kumachepa, zotsatira zophatikizana za kutentha ndi kupanikizika ziyenera kuganiziridwa pa mtundu uwu wa dongosolo. c. Kugwira ntchito mosalekeza: ndiko kuti, kuchuluka kwa ma valve otsegula ndi kutseka kumakhudzanso zofunikira za kukana kuvala. Kwa machitidwe omwe amasinthasintha pafupipafupi, ngati muyika ma valve awiri ayenera kuganiziridwa. (2) Kutsika kovomerezeka kwa dongosolo a. Pamene kuponderezedwa kovomerezeka kwa dongosololi kuli kochepa, kapena kutsika kovomerezeka sikuli kwakukulu koma kuyendetsa kayendetsedwe kake sikofunikira, mtundu wa valve wokhala ndi kutsika kochepa uyenera kusankhidwa, monga valavu ya chipata ndi valve yowongoka ya mpira. B. Ngati kuchuluka kwa kuthamanga kumayenera kuyendetsedwa, mtundu wa valve wokhala ndi kayendetsedwe kabwino ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. (3) Chilengedwe chomwe valavu ili: panja m'malo ozizira, makamaka pazinthu zamankhwala, thupi silikhala lachitsulo koma chitsulo chosapanga dzimbiri (kapena chitsulo chosapanga dzimbiri). 3. Ntchito ya valve (1) Kudula: Pafupifupi ma valve onse adula ntchito. Kungogwiritsidwa ntchito kudula popanda kusintha kayendetsedwe kake kungasankhidwe valavu ya chipata, valavu ya mpira, ndi zina zotero, kudula mwamsanga, tambala, valavu ya mpira, valavu ya butterfly ndiyoyenera kwambiri. Valve yapadziko lonse lapansi imatha kusintha kayendedwe kake ndikudula. Vavu ya butterfly imathanso kukhala yoyenera kusintha kwakukulu koyenda. (2) kusintha kayendedwe ka kayendedwe kake: kusankha njira ziwiri (zofanana ndi L) kapena njira zitatu (zofanana ndi T) valavu ya mpira kapena tambala, zimatha kusintha mwamsanga kayendetsedwe ka zinthu, komanso chifukwa valavu imagwira ntchito. awiri kapena kuposerapo molunjika kudzera mu mavavu, akhoza kufewetsa ntchito, kupanga lophimba molondola, ndipo akhoza kuchepetsa danga. (3) Kuwongolera: valavu yapadziko lonse lapansi, valavu ya plunger imatha kukumana ndi malamulo oyenda bwino, valavu ya singano ingagwiritsidwe ntchito kusintha pang'ono; Pakuthamanga kwakukulu kwa kayendetsedwe kokhazikika (kupanikizika, kutuluka), valve yotsekemera ndiyoyenera. (4) Chongani: Chongani valavu angagwiritsidwe ntchito kuteteza zinthu kubwerera. (5) Mavavu okhala ndi zina zowonjezera amatha kusankhidwa pazinthu zosiyanasiyana zopangira, monga mavavu okhala ndi jekete, okhala ndi mpweya ndi bypass, ndi mavavu okhala ndi mpweya kuti apewe kuyika kolimba. 4, mphamvu ya valavu yosinthira Mu situ yochuluka ya valve yokhala ndi gudumu lamanja, ndikugwira ntchito ndi mtunda wina, ingagwiritsidwe ntchito sprocket kapena ndodo yowonjezera. Ma valve ena akulu akulu amapangidwa ndi ma motors chifukwa cha torque yambiri yoyambira. Gawo lofananira la mota yosaphulika liyenera kugwiritsidwa ntchito pamalo osaphulika. Valavu yowongolera kutali: tengani mtundu wa mphamvu ya pneumatic, hydraulic, magetsi, yomwe imatha kugawidwa kukhala valavu ya solenoid ndi valavu yoyendetsedwa ndi mota. Chosankhacho chiyenera kutengera zosowa ndi mphamvu zomwe zilipo. Chida chamagetsi chowongolera valavu ndi choyenera mavavu ena ozungulira (monga valavu ya butterfly, valavu ya mpira ndi damper baffle, ndi zina zotero) ndi zida zofananira. Bracket ingagwiritsidwe ntchito ngati Angle stroke electric actuator. Aluminiyamu aloyi kufa kuponyera chipolopolo, ndi zabwino ndi yosalala, voliyumu yaing'ono, kulemera kuwala, kukonza kwaulere, kukana dzimbiri ndi zinthu zina zabwino kwambiri, chifukwa cha kukula yaying'ono, angagwiritsidwe ntchito malo yopapatiza. Makhalidwe a ntchito ya chipangizo chamagetsi chamagetsi cha valavu 1. Galimoto Yamphamvu YOPHUNZITSIDWA kuti igwire ntchito ya valavu ZOKHUDZA KWAMBIRI ZOYENERA KUYAMBIRA, ZOYENERA KUYAMBIRA PANO NDIPONSE INERTIA. Mapiritsi a Stator ali ndi choteteza chotenthetsera mkati (mtundu wochira wokha). Vavu ikakakamira mosayembekezereka, wotetezayo amawongolera motayimitsa ndikuteteza chitetezo cha zida zonse. 2, voliyumu yaying'ono, torque yayikulu Voliyumu yonse ndi kulemera kwake ndizofanana ndi 1/3 yazinthu zachikhalidwe zofanana; Mphamvu yolowera yonse ndi yaying'ono, torque yotulutsa ndi yayikulu, ndipo malo oyika ofunikira ndi ochepa; Ndi yabwino kwambiri kukhazikitsa ndi kunyamula. 3, valavu kutsegula mawonetseredwe Lens ndi thupi ndi kunja chakudya kalasi galasi kulumikiza, chomangira kutalika ndi wamphamvu, kotero kuti mankhwala palibe kuipitsa, kutentha kukana, angathe kukana matani mvula ya dzimbiri kuwira mu malo oipa. 4, makina oletsa malire chipangizo Ayi, makina oletsa bawuti oyenda ndi malire opangidwa ndi chitsulo chosapanga dzimbiri amatha kusintha njira yoyendera kupita ku Angle yomwe mukufuna. Kuti zitheke kusintha, bolt imayikidwa kunja kwa nyumbayo. Pambuyo pa kusintha kulikonse, malo omwe amafunidwa amatsekedwa ndi mtedza wachitsulo chosapanga dzimbiri. 5. Chogwirira chamanja Chogwirizira Chitsulo chosapanga dzimbiri chingagwiritsidwe ntchito kuyendetsa valavu kuti itembenuke pamene mukuyimitsa kapena kuzimitsa, S yoyang'ana molunjika, O panjira yotsutsana ndi wotchi. 6, zida zolondola AMAPANGIDWA NDI MAGAYA AMBIRI NDI MITUNDU YA PRECISE TANGENT. Magiya ndi ma shaft amapangidwa ndi chitsulo chotenthetsera chotenthetsera, chomwe chimakhala ndi mphamvu zambiri komanso kupirira bwino ndipo chimatha kupirira kutopa kwanthawi yayitali. Mafuta oyambira amtundu wa molybdenum amawonjezedwa mumakina amagetsi kuti amalize kuthirira popanda kuyang'anira kapena kukonza. 7. Chingwe mawonekedwe Okonzeka ndi ziwiri G1/2 madzi zolumikizira chingwe kwa chingwe ndi chizindikiro zingwe kupewa kusokoneza. 8, Micro switch HD mndandanda kusankha chosinthira yaying'ono kunja, mtundu wolumikizana, moyo wochitapo kanthu, magwiridwe antchito ndi zisonyezo zina ndizabwino komanso zodalirika. 9. Makina a Servo Ma module owongolera omwe amamangidwa nthawi zonse amafanizira chizindikiro cholowera ndi chizindikiro cha potentiometer. Mulingo ukafika, mota imasiya kugwira ntchito, ndipo shaft yotulutsa imasunga valavu pamalo ofananirako mpaka chizindikiro cholowera chisinthe. Onetsetsani kusintha kosalekeza kwa kutsegula kwa valve. 10. Control module The resin encapsulated control module ili ndi mbali zabwino kwambiri za kuwonongeka kwakukulu, ntchito yamphamvu, kukana kugwedezeka, moyo wautali ndi kudalirika. 11, potentiometer yolondola idatumizidwa potentiometer yolondola kwambiri, moyo wautumiki mpaka nthawi zikwi makumi atatu! Zoyenera kwambiri pazofunikira zosinthira ma valve ang'onoang'ono! Onetsetsani bwino kusintha kwa valve yamagetsi. 12. Automatic control Intelligent Integrated chipangizo ndi chizindikiro 4 ~ 20mADC athandizira ndi linanena bungwe akhoza kulamulidwa ndi kompyuta PLC ndi DCS dongosolo, ulamuliro molingana ndi malo, popanda kulamulira pamanja, udindo kudzitsekera, kugwirizana yosavuta, khola ndi odalirika ntchito, mkulu kulamulira molondola. , kufulumira kuchitapo kanthu.
