Kodi tiyenera kulabadira chiyani poika mavavu a mapaipi? Kugwiritsiridwa ntchito ndi mfundo yogwirira ntchito yodzipangira yokha kuthamanga kwa valve

M'mapaipi amadzimadzi, valavu ndiye chinthu chowongolera, ntchito yake yayikulu ndikulekanitsa zida ndi mapaipi, kuwongolera kutuluka, kupewa kubwereranso, kuwongolera ndi kutulutsa kuthamanga. Angagwiritsidwe ntchito kulamulira otaya mpweya, madzi, nthunzi, mitundu yonse ya zowononga TV, matope, mafuta, madzi zitsulo ndi wailesi radioactive. Chifukwa dongosolo la mapaipi kusankha valavu yoyenera n'kofunika kwambiri, pomanga, khalidwe la unsembe valavu payipi, zimakhudza mwachindunji tsogolo ntchito yachibadwa, choncho ayenera kulabadira.
Yang'anani zinthu musanayike
1. Yang'anani mosamala ngati chitsanzo cha valve ndi ndondomeko ikukwaniritsa zofunikira za kujambula.
2, yang'anani ngati tsinde ndi chimbale zimatseguka mosinthika, ngati pali chokhazikika komanso chopindika.
3. Onani ngati valavu yawonongeka, komanso ngati ulusi wa valve ndi wowongoka komanso wosasunthika.
4, fufuzani ngati kuphatikiza kwa mpando wa valve ndi thupi la valve kuli kolimba, diski ya valve ndi mpando wa valve, chivundikiro cha valve ndi thupi la valve, tsinde la valve ndi disc valve.
5. Yang'anani ngati ma valve padding, kulongedza ndi zomangira (maboliti) ali oyenerera zofunikira za chikhalidwe cha sing'anga yogwirira ntchito.
6, zakale kapena zogwiritsidwa ntchito kwa nthawi yayitali ziyenera kuchotsedwa, fumbi, mchenga ndi zinyalala zina ziyenera kutsukidwa ndi madzi.
7, *** kutsegula chisindikizo, fufuzani digiri yosindikiza, valavu ya valve iyenera kutsekedwa mwamphamvu.
Zofunikira pakuyika
1. Kuyika kwa valve sikuyenera kusokoneza ntchito, kusokoneza ndi kukonza zipangizo, payipi ndi thupi la valve palokha, ndipo maonekedwe a msonkhano ayenera kuganiziridwa.
2, valavu pa payipi yopingasa, tsinde la valve limayikidwa mmwamba, kapena kupendekera ku Angle inayake, silingayikidwe pansi pa gudumu lamanja. Valavu, tsinde ndi handwheel pa chitoliro chapamwamba chapamwamba chikhoza kuikidwa molunjika, ndipo kutsegula ndi kutseka kwa valve kungathe kuyendetsedwa patali ndi unyolo pamalo otsika otsika.
3, symmetrical dongosolo, mwaukhondo ndi wokongola; Kwa valavu pa chokwera, ngati njirayo ikuloleza, gudumu lamanja la valve liyenera kuyendetsedwa pamtunda wa chifuwa, nthawi zambiri 1.01.2m kuchokera pansi, ndipo tsinde la valve liyenera kuikidwa pambali pa woyendetsa.
4, valavu kumbali ndi mbali yokwera, kukwera kwa mzere wapakati ndi koyenera kwambiri, ndipo mtunda wa ukonde pakati pa handwheel ndi wosachepera 100mm; Mavavu a mizere yopingasa mbali ndi mbali ayenera kugwedezeka kuti muchepetse kusiyana kwa mapaipi.
5. Mukayika ma valve olemera pa mapampu a madzi, osinthanitsa kutentha ndi zipangizo zina, zothandizira ma valve ziyenera kukhazikitsidwa; Pamene valavu ikugwiritsidwa ntchito kawirikawiri ndikuyika pamwamba pa 1.8m kuchokera kumalo ogwiritsira ntchito, malo ogwiritsira ntchito okhazikika ayenera kuperekedwa.
6, thupi la valavu lili ndi chizindikiro cha muvi, muvi wolozera ndi njira yoyendetsera sing'anga. Mukayika valavu, samalani kuti muviwo uloze mbali imodzi ndi sing'anga yomwe ili mupaipi.
7. Mukayika ma valve a flange, onetsetsani kuti mapeto a ma flanges awiri ali ofanana ndi okhazikika, ndipo musagwiritse ntchito ma gaskets awiri.
8. Mukayika ma valve opangidwa ndi ulusi, valavu yokhala ndi ulusi iyenera kukhala ndi kugwirizana kwamoyo kuti iwonongeke mosavuta. Kukhazikitsa kwa kugwirizana kwamoyo kuyenera kuganizira za kuwongolera, nthawi zambiri madzi amayenda kudzera mu valve ndiyeno kudzera pa kugwirizana kwamoyo.
Cholinga ndi mfundo ya kudzidalira mtundu kuthamanga kuchepetsa valavu Kudzidalira mtundu kuthamanga kuchepetsa valavu ndi ulamuliro valavu lotseguka-kutseka mbali ya kutsegula kwa thupi kusintha otaya sing'anga, sing'anga kuthamanga kuchepetsedwa, nthawi yomweyo. nthawi mothandizidwa ndi gawo la valavu mutatha kupanikizika sinthani kutsegula kwa gawo lotseguka, sungani valavu pambuyo pa kupanikizika mkati mwamtundu wina, pansi pa chikhalidwe cha kusintha kwa mpweya wolowera, sungani kuthamanga kwa kutuluka mkati mwa kukula kwa seti. , Tetezani zotsatila zanyumba ndi zida zopangira.
Cholinga ndi ntchito yayikulu: valavu ndi yoyenera madzi, nthunzi, payipi yapakati pamlengalenga, posintha mphamvu yolowera kuti ichepetse kupanikizika kofunikira, pamene kulowetsedwa ndi kutuluka kwasintha, ndi mphamvu ya sing'anga yokhayokhayo imasunga kuthamangitsidwa kotulutsa mkati mwamitundu ina, koma kukakamiza kolowera ndi kutulutsa kotulutsa kuyenera kukhala ≥0.2MPA/CM
Mfundo yogwirira ntchito ndi kapangidwe: Pamene valavu yochepetsera kuthamanga imaperekedwa, Kusintha kasupe mu chikhalidwe chosagwedezeka, panthawiyi valavu yaikulu ya valavu ndi kulipira chimbale mu boma chatsekedwa, pamene ntchito molingana ndi wotchi kusintha wononga, psinjika kusintha kasupe, kupanga nembanemba valavu lotseguka kusuntha malipiro chimbale, sing'anga ndi dzenje polipira mpando kwa b mabowo mu pisitoni pamwamba, pisitoni pansi zochita za sing'anga kuthamanga, kusiya kusuntha pansi kulimbikitsa valavu yaikulu mpando valavu, kupanga sing'anga otaya valavu. Ndi c pansi pa dzenje mu diaphragm panthawi imodzimodziyo, pamene valavu itatha kupanikizika kwambiri kuposa kukakamiza, kukankhira diaphragm mmwamba kulamulira kupanikizika kwa kasupe, kulipira chimbale kutseka njira, ndiye kuchepetsa kutuluka mu pisitoni pamwamba pa sing'anga, kutsika kutsika, komanso panthawiyi valavu yaikulu ya valavu pazitsulo zazikulu za valve disc kasupe kukankhira pansi, chilolezo cha diski yaikulu ya valve ndi mpando waukulu umachepetsedwa, kutuluka kwapakati kumakhala kochepa, valavu pambuyo pa kupanikizika mphamvu imatsikiranso pamlingo watsopano, m'malo mwake, pamene kupanikizika pambuyo pa valavu kumakhala kotsika kusiyana ndi kupanikizika kokhazikika, kusiyana pakati pa diski yaikulu ya valve ndi mpando waukulu wa valve kumawonjezeka, kutuluka kwapakati kumawonjezeka, kotero kuti kupanikizika pambuyo pake. valavu imawonjezeranso kuti ifike pamlingo watsopano.
Okondedwa Makasitomala,
Moni, kampani yathu ndi gulu lachitukuko chapamwamba kwambiri lomwe lili ndi mphamvu zaukadaulo, limapereka zinthu zabwino kwambiri, mayankho athunthu komanso ntchito zaukadaulo zapamwamba kwa ogwiritsa ntchito ambiri. Zogulitsa zazikulu ndi valavu yosindikizira ya nayitrogeni, chipangizo chosindikizira cha nayitrogeni, valavu yodziyendetsa yokha yochepetsera mphamvu. Bizinesiyo imatsatira cholinga cha chikhulupiriro chabwino, chabwino, chochita bizinesi, ndi njira zolimba zokwerera nsonga zatsopano, kupereka zopereka kumakampani opanga ma automation, kulandira makasitomala atsopano ndi akale khalani otsimikiza kuti agula zomwe amakonda. Tidzakutumikirani ndi mtima wonse!
