1. Kukonza valavu pachipata
1.1 Zigawo zazikulu zaukadaulo:
DN: NPS1”~ NPS28”
PN: CL150 ~ CL2500
Zida zigawo zikuluzikulu: ASTM A216 WCB
Tsinde-ASTM A276 410; Mpando—ASTM A276 410;
Nkhope yosindikiza—VTION
1.2 Miyezo Yogwiritsidwa Ntchito: API 6A、API 6D
1.3 Kapangidwe ka valve (onani mkuyu 1)
Fig.1 vavu yachipata
2. Kuyendera ndi kukonza
2.1: Kuyang'ana kunja:
Yang'anani pamwamba pa valavu kuti muwone ngati pali kuwonongeka, ndiyeno muwerenge; Lembani mbiri.
2.2 Onani chipolopolo ndikusindikiza:
Yang'anani ngati pali vuto linalake ndipo lembani zowunikira.
3. Kupasuka kwa Vavu
Vavu iyenera kutsekedwa musanaphwasule ndikumasula mabawuti olumikizira. Ayenera kusankha sipanala yoyenera yosasinthika ku ma bolts，Mtedza udzawonongeka mosavuta ndi sipikani chosinthika.
Maboti a dzimbiri ndi mtedza ayenera kuthiridwa ndi palafini kapena chochotsera dzimbiri; Yang'anani kumene ulusi wa screw ukupita ndikupotoza pang'onopang'ono. Zigawo zowonongeka ziyenera kuwerengedwa, kuzilemba ndi kusungidwa mwadongosolo. Tsinde ndi chipata cha chipata chiyenera kuikidwa pa bulaketi kuti zisawonongeke.
3.1 Kuyeretsa
Onetsetsani kuti zida zotsalira zayeretsedwa mofewa ndi burashi ndi Palafini, petulo, kapena zoyeretsera.
Mukamaliza kuyeretsa, onetsetsani kuti zida zotsalira sizikhala ndi mafuta komanso dzimbiri.
3.2 Kuyang'ana zida zosinthira.
Yang'anani mbali zonse zotsalira ndikulemba mbiri.
Pangani dongosolo loyenera lokonzekera molingana ndi zotsatira zoyendera.
4. Kukonza zida zosinthira
Konzani zotsalirazo molingana ndi zotsatira zoyendera ndi dongosolo lokonzekera; sinthani zida zosinthira ndi zida zomwezo ngati pakufunika.
4.1 Kukonza Gate:
①Kukonza T-slot: kuwotcherera kutha kugwiritsidwa ntchito pokonza fracture ya T-slot, Kupotoza koyenera kwa T-slot, Weld mbali zonse ziwiri ndi bar yolimbitsa. Kuwotcherera pamwamba kungagwiritsidwe ntchito kukonzanso T-slot pansi. Pogwiritsa ntchito kutentha kwa kutentha pambuyo pa kuwotcherera kuti muchepetse kupsinjika ndikugwiritsa ntchito kulowa kwa PT kuti muyang'ane.
②Kukonza zogwetsedwa:
Kugwetsa kumatanthauza kusiyana kapena kusuntha kwakukulu pakati pa nkhope yosindikiza pachipata ndi nkhope yosindikiza Mpando. Ngati kufanana chipata valavu watsika, akhoza kuwotcherera pamwamba ndi pansi mphero, ndiye, ndondomeko akupera.
4.2 Kukonza nkhope yosindikiza
Choyambitsa chachikulu cha kutayikira kwa ma valve mkati ndikusindikiza kuwonongeka kwa nkhope. Ngati kuwonongeka kuli kwakukulu, muyenera kuwotcherera, Machining ndikupera kusindikiza nkhope. Ngati si chachikulu, kokha akupera. Kupera ndiyo njira yaikulu.
a. The Basic mfundo akupera:
Lowani pamwamba pa akupera chida pamodzi workpiece. Lowetsani abrasive mu mpata pakati pa malo, ndiyeno sunthani chida chopera kuti chipere.
b. Kupera kwa nkhope yosindikiza pachipata:
Mchitidwe akupera: manual mode ntchito
Pakani abrasive pa mbale mofanana, ikani workpiece pa mbale, ndiyeno tembenuzani pamene mukupera molunjika kapena "8" mzere.
4.3 Kukonza tsinde
a. Ngati kukanda kulikonse pankhope yodinda tsinde kapena pamalo olimba sikungafanane ndi kapangidwe kake, nkhope yosindikizira iyenera kukonzedwa. Kukonza njira: lathyathyathya akupera, Zozungulira akupera, yopyapyala akupera, makina akupera ndi Cone akupera;
b. Ngati tsinde la valavu likupindika> 3%, yesetsani kuwongola chithandizo ndi makina ochepera opera kuti mutsimikize kutha kwa pamwamba ndi kukonza kuzindikira ming'alu. Njira zowongola: Kuwongola kwa static, kuwongola kozizira ndi kuwongola kwa kutentha.
c. Kukonza mutu wa tsinde
Mutu wa tsinde umatanthawuza mbali za tsinde (tsinde, pamwamba pa tsinde, mphero pamwamba, zolumikizira ndi zina) zolumikizidwa ndi mbali zotseguka ndi zotseka. Kukonza njira: kudula, kuwotcherera, amaika mphete, amaika pulagi etc.
d. Ngati sizingakwaniritse zofunikira zowunikira, ziyenera kupangidwanso ndi zinthu zomwezo.
4.4 Ngati kuwonongeka kulikonse ndi pamwamba pa flange mbali zonse za thupi, ayenera kukonza Machining kuti zigwirizane ndi zofunika muyezo.
4.5 Mbali zonse ziwiri za RJ zolumikizira thupi, ngati sizingafanane ndi zomwe zimafunikira pakakonzedwa, ziyenera kuwotcherera.
4.6 Kusintha kwa zida zovala
Kuvala mbali kumaphatikizapo gasket, kulongedza, O-ring etc. Konzekerani kuvala mbali molingana ndi zofunikira zosamalira ndikulemba mbiri.
5. Sonkhanitsani ndi kukhazikitsa
5.1 Kukonzekera: Konzani zida zosinthira, gasket, kulongedza, zida zoyika. Ikani zigawo zonse mu dongosolo; musagone pansi.
5.2 Chekeni choyeretsera: Malo oyeretsera (chomangira, kusindikiza, tsinde, mtedza, thupi, boneti, goli ndi zina) ndi Palafini, petulo kapena woyeretsa. Onetsetsani kuti palibe mafuta ndi dzimbiri.
5.3 Kuyika:
Poyamba, yang'anani indentation ya tsinde ndi chipata kusindikiza nkhope kutsimikizira kulumikiza zinthu;
Pukutani, pukutani thupi, bonati, chipata, kusindikiza nkhope kuti ikhale yoyera, Ikani zida zosinthira mwadongosolo ndikumangitsa mabawuti molingana.
