Kukonzekera kwa ma valve opangira mafakitale opangira makina opangira ma valve odziyendetsa okha

Kukonzekera kwa ma valve opangira mafakitale opangira ntchito yokonza zofunikira zonse zodziyendetsa pawokha kutentha kwa valve ntchito Njira yochitira valavu, yodziyendetsa yokha 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. Kuyika kosavomerezeka kumaphatikizapo kulephera kwa galimoto, mpando wokhazikika, spool wakufa, ndi zina zotero. Kulephera kwa ntchito molingana ndi mtundu wa valavu ndi kosiyana ... Gulu 1 Muyezo uwu umalongosola zofunikira zonse pakuyika, kugwiritsa ntchito ndi kukonza ma valve azitsulo zamakampani. 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'mabuku otsatirawa zimakhala zofunikira za Mafotokozedwewa 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. GB/T 13927 Kuyeza kwa ma valve opangira mafakitale (GB/T 13927 2008,ISO/DIS 5208:2007,MOD) JB/T 9092 kuyesa ma valve ndi kuyesa 3 Tanthauzo la Mawu Mawu ndi matanthauzo otsatirawa akugwiritsidwa ntchito pa izi. Connection mode tonnect} pa mode Vavu nsonga ndi chitoliro kapena zipangizo kupeza mawonekedwe, kuphatikizapo looper flange, flange kulumikiza, ulusi kulumikiza poyambira, ndi zina zotero. galimoto njira kuyendetsa micans Actuating vavu kanthu njira, self- actuating ndi 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 masitayelo pantchito Mavavu ogwirira ntchito amaphatikizapo kutseguka ndi kutseka, nthawi zambiri kutsekedwa, kachitidwe kakang'ono ka ntchito, kachitidwe ka ntchito kosalekeza, kachitidwe ka nthawi yozungulira. 3.4 kulephera kwa valve Kulephera kwa valve kumaphatikizapo kulephera kwa chisindikizo, kulephera kwa kaimidwe, kulephera kwa ntchito, ndi zina zotero. 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 vavu, fufuzani kuti chiphaso choyenerera cha malonda ndi bukhu lokhazikitsa ndi ntchito la valve ndi lathunthu komanso lovomerezeka. 4.1.2 Kuyang'anira maonekedwe kudzachitika musanayambe kuyika ma valve, omwe adzatsatire zotsatirazi: a) Pamwamba pasakhale ndi ming'alu, mabowo a mchenga, kuwonongeka kwa makina, dzimbiri, madontho ndi zofooka 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 chivundikiro chotetezera 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 yotsegula ndi kutseka kuwunika ndi kuyesa kukakamiza Vavu (kupatula valavu) Kusinthana kuyenera kukhala kosavuta, 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. Kuyesa kwa ma valve pamakampani a petrochemical ndi magawo ofananirako kudzachitika molingana ndi zofunikira za JB/T 9092, ndipo kuyesa kwa valve yamafuta ambiri 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 usakhazikike. 4.2.1.4 Valavu yokwezera cheke iyenera kukhala yokhazikika, mawondo a valavu opindika ayenera kukhala amtundu. 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. The actuating mechanism 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. Pochita kukonza nthawi zonse ndikuwongolera valavu, mwayi wolephera wamba umachepetsedwa. Kudzidalira pawokha kuwongolera kutentha valavu yodziyimira payokha ukadaulo wowongolera kutentha (1) Vavu yodzilamulira yokha (malo ozindikira kutentha kwamkati) polowera kutentha ndi kuwongolera kutentha. (2) Valavu yodzilamulira yokha (capillary kunja kutentha kutentha) polowera kutentha ndi kutulutsa kutentha. 2. Mavuto ogwiritsira ntchito adachitika (1) Spool yakhazikika; (2) Valavu silingatsegulidwe; (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 zothanirana ndi kukonza ndi kukonza (1) Kuwunika koyenera kwapachaka kusanachitike, kuthekera kwa kulephera kofala kumakhala kwakukulu 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, kumabweretsa 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.
