Kukonza ma valve opangira mafakitale opangira makina opangira ma valve okhazikika odzilamulira okha

Njira yochitira ma valve, yodziyendetsa nokha komanso mphamvu yakunja. Kudzidalira kumatanthawuza kapangidwe ka mkati mwa valavu yopangidwa ndi kusintha kwa zinthu zomwe zimagwira ntchito, kutentha ndi mphamvu zina zoyendetsera chigawo cha valve zigawo zosiyanasiyana zosuntha; Kuyendetsa kwamphamvu kunja kumatanthauza kugwiritsa ntchito mphamvu yakunja kuyendetsa magawo osiyanasiyana osuntha apakati pa valve, kuphatikiza pamanja, magetsi, pneumatic, hydraulic control valve, electromagnetic induction drive ndi njira zoyendetsera izi. Vavu yosalondola imaphatikizapo kusindikiza kosavomerezeka, kaimidwe kosavomerezeka, kulephera kugwira ntchito, ndi zina zotero. Kuthina kosavomerezeka kumaphatikizapo kutsekedwa ndi kutuluka kwa mpweya. Kaimidwe kosavomerezeka kumaphatikizapo kulephera kwa galimoto, kukhala pampando, kufa kwa spool, ndi zina zotero. Kulephera kwa ntchito molingana ndi mtundu wa valve ndikosiyana...

Muyezo uwu umafotokoza zofunikira zonse pakuyika, kugwiritsa ntchito ndi kukonza ma valve achitsulo m'mafakitale.
Izi zimagwiranso ntchito ku ma valve a globe, ma valve a globe, ma valve opumula, ma valve a pachipata, ma valavu a disc, ma valve agulugufe a pneumatic, ma valavu a pulagi, ma cheke, ma valve, ma valve owongolera kupanikizika, misampha ya nthunzi, ma valve owongolera ndi ma valve ena.
2 Zolemba zodziwika bwino
Zomwe zili m'malemba otsatirawa zimakhala zofunikira za Mfundoyi molingana ndi kukhazikitsidwa kwa izi. Ngati chikalata chili ndi deti, kusintha kulikonse kotsatira (popanda erratum) kapena kusinthidwanso sikuli koyenera pa izi. Komabe, ngati chikalata sichinatchulidwe, nambala yamtundu wa nambalayo idzagwiritsidwa ntchito pazolinga zake kulimbikitsa kafukufuku wasayansi wosiyanasiyana kuti agwirizane ngati chikalatacho chingagwiritsidwe ntchito.

Nsonga ya vavu ndi chitoliro kapena mawonekedwe ofikira zida, kuphatikiza looper flange, kulumikizana kwa flange, kulumikizana kwa ulusi, kulumikizana kwa groove, ndi zina.
njira yoyendetsera galimoto yoyendetsa maikolofoni
Njira yochitira ma valve, yodziyendetsa nokha komanso mphamvu yakunja. Kudzidalira kumatanthawuza kapangidwe ka mkati mwa valavu yopangidwa ndi kusintha kwa zinthu zomwe zimagwira ntchito, kutentha ndi mphamvu zina zoyendetsera chigawo cha valve zigawo zosiyanasiyana zosuntha; Kuyendetsa kwamphamvu kunja kumatanthauza kugwiritsa ntchito mphamvu yakunja kuyendetsa magawo osiyanasiyana osuntha apakati pa valve, kuphatikiza pamanja, magetsi, pneumatic, hydraulic control valve, electromagnetic induction drive ndi njira zoyendetsera izi.
3.3 Ntchito ya masitayilo kuntchito
Njira yogwirira ntchito ya valve imaphatikizapo kutseguka ndi kutseka, nthawi zambiri kutsekedwa, kachitidwe kakang'ono ka ntchito, kachitidwe ka ntchito kosalekeza, kachitidwe ka nthawi yozungulira nthawi.
3.4 kulephera kwa valve Kulephera kwa valve
Kulephera kwa mavavu kumaphatikizapo kulephera kwa chisindikizo, kulephera kwa kaimidwe, kulephera kugwira ntchito, ndi zina zotero. Kuthina kosavomerezeka kumaphatikizapo kuwonekera ndi kutuluka kwa mpweya. Kuyika kosavomerezeka kumaphatikizapo kulephera kwa galimoto, mpando wokhazikika, spool wakufa, ndi zina zotero. Kulephera kwa ntchito kumasiyanasiyana malinga ndi mitundu yosiyanasiyana ya valve, monga kusintha valavu molakwika, kuthetsa kusasunthika kwa kupanikizika kwa ntchito, valavu osati molingana ndi zomwe zikugwiritsidwa ntchito.
4 Kuyika
4.1 Kukonzekera Kuyika
4.1.1 Musanakhazikitse valavu, fufuzani kuti chiphaso cha chiyeneretso cha mankhwala ndi bukhu lokhazikitsa ndi ntchito la valve ndi lathunthu komanso lovomerezeka.
4.1.2 Kuyang'anira maonekedwe kudzachitika musanakhazikitse ma valve, omwe adzatsatire izi:
a) Pamwamba pasakhale ming'alu, mabowo amchenga, kuwonongeka kwa makina, dzimbiri, madontho ndi zolakwika zina;
b) Dzina la fakitale silidzagwa, ndipo magawo a ntchito mu fakitale nameplate amagwirizana ndi mfundo zazikuluzikulu za dongosolo;
c) Mbali zonse ziwiri za valve ziyenera kusungidwa ndi chitetezo choteteza chitetezo.
d) Pasakhale madzi osungira, dzimbiri, madontho ndi kuwonongeka mu bolodi la dera la mafuta;
e) Sipadzakhala utoto pazitsulo zolumikizidwa ndi flange, screw idzakhala yosasunthika, kusindikiza pamwamba pa flange sikudzawonongeka ndi axial pipe groove ndi zinthu zina, ndipo kuwotcherera kwa magetsi kudzakhala kosatheka. pasakhale kuwotcherera makina kuwonongeka;
f) valavu yachitetezo chamtundu wa masika kuti muwone kukhulupirika kwa chisindikizo. Vavu yamtundu wa ndodo iyenera kukhala ndi zida zoyikira nyundo zolemera;
g) Pakatikati mwa thupi la chitoliro cha rabara, dziwe lopangidwa ndi porcelain ndi valavu yapulasitiki yokhala ndi pulasitiki iyenera kukhala yosalala, nsalu ndi zinthu zapansi ziyenera kuphatikizidwa mwamphamvu, popanda ming'alu, ziphuphu ndi zolakwika zina.
4.1.3 Valve kutsegula ndi kutseka kuyendera ndi kupanikizika
Vavu (kupatulapo valavu) yosinthira iyenera kukhala yomvera, chizindikiro cha malo molondola. Musanayambe kukhazikitsa, sinthani pamanja mphamvu ya valve katatu kuti muwone ngati pali vuto.
Vavu (kupatula valavu) idzasiyidwa fakitale kwa nthawi yopitilira chaka chimodzi, ndipo ikuyembekezeredwa kuti iyese kukakamiza pansi pamikhalidwe. Mayeso a valve pamakampani a petrochemical ndi magawo ofananira adzachitidwa molingana ndi zofunikira za JB/T 9092, ndipo kuyesa kwa ma valve a mafakitale kudzachitika molingana ndi zomwe GB/T 13927.
4.2 Kuyika
4.2.1 Zofunikira Zonse
4.2.1.1 Werengani buku loyika mosamala musanayike valavu.
4.2.1.2 Mavavu otchulidwa kuti alowemo adzaikidwa malinga ndi zofunikira za valve.
4.2.1.3 Nthawi zambiri, chopondera cha valve sichiyenera kuyikidwa pansi kuti mpando usamangidwe.
4.2.1.4 Valavu yokwezera cheke iyenera kukhala yokhazikika, mawondo a valavu yoyang'ana valavu ayenera kukhala ofanana.
4.2.1.5 Pali valavu yotulutsa chitetezo, ndipo valavu yotulutsa iyenera kukhala ndi chitoliro chotulutsira, ndipo kutulutsa kwake sikuyenera kuyang'anizana ndi woyendetsa.
4.2.1.6 Malo oyika ma valve ayenera kukhala abwino kuti agwire ntchito ndi kukonza.
Njira yoyendetserayi imakakamira chifukwa chakuwonongeka kwa kasupe wa carbon steel torsion pogwiritsira ntchito valavu yodziyendetsa yokha. Vutoli linathetsedwa posintha kasupe wa torsion kukhala chitsulo chosapanga dzimbiri. (4) Kwa mapaipi amene sagwiritsidwa ntchito mocheperapo, zigawo zina zimakakamira chifukwa mavavu odziyendetsa okha sagwira ntchito kwa nthawi yayitali. Mwa kukonza nthawi zonse ndikuwongolera ma valve, mwayi wolephera wamba umachepetsedwa.
Self - operating control valve application status
Ukadaulo wodziyimira pawokha wowongolera kutentha kwa valve key processing
(1) Valavu yodzilamulira yokhayokha (malo ozindikira kutentha amkati) polowera cholumikizira kutentha ndi kuwongolera kutentha.
(2) Valavu yodzilamulira yokha (capillary kunja kutentha kutentha) polowera kutentha ndi kutulutsa kutentha.
2. Mavuto ogwiritsira ntchito achitika
(1) Nkhope yakakamira;
(2) Valavu sangathe kutsegulidwa;
(3) ofunda capillaries dehysis;
(4) The actuator yakanidwa;
(5) Mapangidwe amkati a actuator amawonongeka pambuyo pa condensate;
(6) Chingwe chaching'ono cha actuator sichingatulutsidwe pambuyo potsekedwa;
(7) Kutaya kwa valve ndi kwakukulu.
3 Njira zowongolera ndi kukonza
(1) Musanayambe kuyang'ana kwapachaka koyenera, mwayi wa zolephera wamba ndi waukulu kwambiri. Kuwonjezeka wachibale Mwina wa anayendera chaka chino. Zomwe zili mu kuyendera kwa chaka chino ndi: fufuzani ngati pali vuto lililonse ndi dongosolo lokonzekera, pamanja kusintha kutentha, kuti muwone ngati pali malo ofanana a valve yosinthira; Onani kutulutsa kwa capillary.
(2) Chifukwa cha kusankha kwa thovu guluu kuchita kutentha kutentha, chifukwa cha thovu guluu mu valavu, kuti valavu munakhala. Pambuyo posintha njira yotetezera kutentha, vutoli limathetsedwa pakapita nthawi.
(3) The actuator anakanidwa chifukwa dzimbiri carbon steel torsion kasupe. Vutoli linathetsedwa posintha kasupe wa torsion kukhala chitsulo chosapanga dzimbiri.
(4) Kwa mapaipi amene sagwiritsidwa ntchito mocheperapo, zigawo zina zimakakamira chifukwa mavavu odziyendetsa okha sagwira ntchito kwa nthawi yayitali. Kukonzekera nthawi zonse ndi kuwongolera kumachitika kuti valavu ichepetse mwayi wolephera wamba.
