BS 1873 Globe Valve Bolted Bonnet
✧ Kufotokozera
Muyezo wa BS 1873 umatanthawuza ku British Standard kwa mavavu apadziko lonse okhala ndi ma boniti opindika. Mawu akuti "BS 1873" akusonyeza kuti valavu ikugwirizana ndi miyezo yokhazikitsidwa ndi British Standards Institution (BSI) ya mtundu uwu wa valve. kuthamangitsa kutuluka kwa madzimadzi mu payipi. Mapangidwe a bonnet opangidwa ndi bolts amalola kuti azitha kulowa mkati mwa valavu pofuna kukonza ndi kukonza zolinga.Ma valvewa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo mafuta ndi gasi, petrochemical, magetsi opangira magetsi, ndi malo opangira madzi. Valavu ya globe ya bolt ndi yoyenera kugwiritsidwa ntchito pamene kutsekedwa kolimba kumafunika ndipo pamene kukonzanso kawirikawiri kapena kuyang'anira ma valve mkati ndikofunika. kuonetsetsa kudalirika kwawo ndi magwiridwe antchito. Njirazi zingaphatikizepo mafotokozedwe a zipangizo, kutentha kwa kutentha, kugwirizana kwa mapeto, ndi zinthu zina zofunika.Pofotokoza kapena kusankha valavu ya BS 1873 ya globe yokhala ndi boniti yotsekedwa, ndikofunika kulingalira zinthu monga momwe ntchito ikufunira, mikhalidwe yogwirira ntchito, katundu wamadzimadzi, kuthamanga ndi kutentha, ndi miyezo kapena malamulo aliwonse amakampani. Ngati muli ndi mafunso okhudza muyezo wa BS 1873.
✧ Mawonekedwe a BS 1873 Globe Valve Bolted Bonnet
1. Kutsegula ndi kutseka popanda kukangana. Ntchitoyi imathetsa vutolo kuti kusindikiza kwa ma valve achikhalidwe kumakhudzidwa ndi kukangana pakati pa malo osindikizira.
2, mawonekedwe amtundu wapamwamba. Vavu yomwe imayikidwa papaipi imatha kuyang'aniridwa mwachindunji ndikukonzedwanso pa intaneti, zomwe zimatha kuchepetsa kuyimitsidwa kwa chipangizocho ndikuchepetsa mtengo.
3, kapangidwe ka mpando umodzi. Vuto lomwe sing'anga mu valavu ya valve imakhudzidwa ndi kuwonjezereka kwamphamvu kwamphamvu kumathetsedwa.
4, mapangidwe otsika a torque. Tsinde la valve yokhala ndi mapangidwe apadera amatha kutsegulidwa mosavuta ndi kutsekedwa ndi chogwirira chaching'ono chamanja.
5, kamangidwe kusindikiza mphero. Valavu imasindikizidwa ndi mphamvu yamakina yoperekedwa ndi tsinde la valavu, ndipo mphero ya mpira imakanikizidwa kumpando, kotero kuti kusindikiza kwa valve sikukhudzidwa ndi kusintha kwa kusiyana kwa payipi, ndipo ntchito yosindikiza ndiyo kutsimikiziridwa modalirika pansi pazikhalidwe zosiyanasiyana zogwirira ntchito.
6. Kudzitchinjiriza kamangidwe ka kusindikiza pamwamba. Mpirawo ukatsetsereka kuchoka pampando, madzi a mupaipi amadutsa 360 ° molingana ndi kusindikiza pamwamba pa mpirawo, zomwe sizimangochotsa kukokoloka kwamadzi othamanga kwambiri pampando, komanso kumachotsa kudzikundikirako. malo osindikizira kuti akwaniritse cholinga chodziyeretsa.
7, valavu m'mimba mwake DN50 pansi pa thupi valavu, valavu chivundikirocho ndi forging zigawo, DN65 pamwamba valavu thupi, valavu chivundikiro ndi kuponyedwa zitsulo mbali.
8, thupi la valavu ndi chivundikiro cha valve zimakhala ndi njira zosiyanasiyana zolumikizirana, kulumikizana kwa pini, kulumikizana kwa flange gasket ndi kulumikiza ulusi wodzisindikiza.
9. Malo osindikizira a mpando wa valve ndi valavu amapangidwa ndi kuwotcherera kwa plasma kapena pamwamba pa cobalt chromium tungsten carbide, yomwe imakhala ndi kuuma kwakukulu, kukana kuvala, kukana abrasion ndi moyo wautali wautumiki.
10, valavu tsinde zakuthupi ndi nitriding chitsulo, nitriding valavu tsinde pamwamba kuuma, kukana kuvala, kukana abrasion, kukana dzimbiri, moyo wautali utumiki.
✧ Ubwino wa BS 1873 Globe Valve Bolted Bonnet
Panthawi yotsegulira ndi kutseka kwa valve yachitsulo yopangidwa ndi zitsulo, chifukwa kukangana pakati pa diski ndi kusindikiza pamwamba pa thupi la valve ndi kochepa kuposa kwa valve yachipata, imakhala yosagwira ntchito.
Kutsegula kapena kutseka kwa tsinde la valve ndi kochepa kwambiri, ndipo kumakhala ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valve kumakhala kofanana ndi kugunda kwa valve disc, ndikoyenera kwambiri kusintha. wa mlingo wotuluka. Choncho, valavu yamtunduwu ndi yoyenera kwambiri kudulidwa kapena kuwongolera ndi kugwedeza.

✧ Pambuyo pa Ntchito Yogulitsa
Monga katswiri wopanga ma valve opangira zitsulo komanso kutumiza kunja, tikulonjeza kupatsa makasitomala ntchito zapamwamba zotsatsa pambuyo pogulitsa, kuphatikiza izi:
1.Kupereka malangizo ogwiritsira ntchito mankhwala ndi malingaliro okonza.
2.Zolephera zomwe zimayambitsidwa ndi zovuta zamtundu wazinthu, timalonjeza kuti tipereka chithandizo chaukadaulo ndikuthana ndi mavuto munthawi yaifupi kwambiri.
3.Kupatula kuwonongeka komwe kumachitika chifukwa chogwiritsa ntchito mwachizolowezi, timapereka ntchito zokonzetsera zaulere komanso zosinthira.
4.Tikulonjeza kuti tidzayankha mwamsanga pa zosowa za makasitomala panthawi ya chitsimikizo cha mankhwala.
5. Timapereka chithandizo chaumisiri cha nthawi yayitali, kuyankhulana pa intaneti ndi ntchito zophunzitsira. Cholinga chathu ndikupatsa makasitomala chidziwitso chabwino kwambiri chautumiki ndikupangitsa zomwe makasitomala akumana nazo kukhala osangalatsa komanso osavuta.
