Boneti Yokhala ndi Valve ya BS 1873 Globe
✧ Kufotokozera
Muyezo wa BS 1873 umatanthauza Muyezo wapadera wa ku Britain wa ma valve a globe okhala ndi maboniti omangidwa. Dzina lakuti "BS 1873" limasonyeza kuti valavu ikutsatira miyezo yomwe yakhazikitsidwa ndi British Standards Institution (BSI) ya mtundu uwu wa valavu. Valavu yozungulira yokhala ndi boniti yomangidwa ndi boniti ndi mtundu wa valavu yomwe imagwiritsidwa ntchito kwambiri powongolera, kulekanitsa, kapena kupondereza kuyenda kwa madzi mupaipi. Kapangidwe ka boniti yozungulira kamalola kuti zinthu zamkati mwa valavu zifike mosavuta pazolinga zokonza ndi kukonza. Ma valve awa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza mafuta ndi gasi, petrochemical, kupanga magetsi, ndi malo oyeretsera madzi. Valavu yozungulira ya boniti yozungulira ndi yoyenera kugwiritsidwa ntchito pomwe pakufunika kutsekedwa mwamphamvu komanso komwe kukonza kapena kuyang'ana pafupipafupi kwa zinthu zamkati za valavu ndikofunikira. Ma valve a globe a BS 1873 okhala ndi maboniti omangidwa nthawi zambiri amatsatira njira zinazake zopangira ndi magwiridwe antchito zomwe zafotokozedwa mu muyezo kuti zitsimikizire kudalirika kwawo komanso kugwira ntchito kwawo. Zofunikira izi zitha kuphatikizapo kufotokozera za zipangizo, kuwerengera kwa kupanikizika ndi kutentha, kulumikizana kumapeto, ndi zina zofunikira. Mukasankha kapena kusankha valavu ya BS 1873 globe yokhala ndi bolnet yolumikizidwa, ndikofunikira kuganizira zinthu monga momwe ikugwiritsidwira ntchito, momwe imagwirira ntchito, mawonekedwe amadzimadzi, zofunikira pa kupanikizika ndi kutentha, ndi miyezo kapena malamulo aliwonse ogwira ntchito m'makampani. Ngati muli ndi mafunso enieni okhudza muyezo wa BS 1873.
✧ Zinthu zomwe zili mu BS 1873 Globe Valve Bolted Bonnet
1. Kutsegula ndi kutseka popanda kugwedezeka. Ntchitoyi imathetsa vuto lonse lakuti kutseka ma valve achikhalidwe kumakhudzidwa ndi kukangana pakati pa malo otsekera.
2, kapangidwe ka mtundu wapamwamba. Valavu yoyikidwa pa payipi ikhoza kuunikidwa ndikukonzedwa mwachindunji pa intaneti, zomwe zingathandize kuchepetsa bwino malo oimika magalimoto ndikuchepetsa mtengo.
3, kapangidwe ka mpando umodzi. Vuto loti cholumikizira chapakati chomwe chili m'mphepete mwa valavu chimakhudzidwa ndi kuwonjezeka kwa kuthamanga kwa magazi kosazolowereka limathetsedwa.
4, kapangidwe ka mphamvu yochepa. Chitsinde cha valavu chokhala ndi kapangidwe kapadera chingatsegulidwe ndi kutsekedwa mosavuta ndi chogwirira chaching'ono cha dzanja.
5, kapangidwe ka kutseka kwa wedge. Valavu imatsekedwa ndi mphamvu yamakina yoperekedwa ndi tsinde la valavu, ndipo wedge ya mpira imakanikizidwa pampando, kotero kuti kutseka kwa valavu kusakhudzidwe ndi kusintha kwa kusiyana kwa kuthamanga kwa payipi, ndipo magwiridwe antchito otseka amakhala odalirika pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito.
6. Kapangidwe kodziyeretsa ka pamwamba potseka. Pamene mpira ukupendekera kutali ndi mpando, madzi omwe ali mu payipi amadutsa mofanana pa 360° pamwamba potseka mpirawo, zomwe sizimangochotsa kuwonongeka kwa madzi othamanga kwambiri pampandowo, komanso zimatsuka kuchulukana kwa madzi otseka kuti akwaniritse cholinga chodziyeretsa.
7, m'mimba mwake wa valavu DN50 pansi pa thupi la valavu, chivundikiro cha valavu chili ndi ziwalo zopangira, DN65 pamwamba pa thupi la valavu, chivundikiro cha valavu ndi ziwalo zachitsulo zotayidwa.
8, thupi la valavu ndi chivundikiro cha valavu zili ndi njira zosiyanasiyana zolumikizirana, kulumikizana kwa pini yolumikizira, kulumikizana kwa gasket ya flange ndi kulumikizana kwa ulusi wodzitsekera.
9. Malo otsekera mpando wa valavu ndi chivundikiro cha valavu amapangidwa ndi plasma spray welding kapena surfacing cobalt chromium tungsten carbide, yomwe ili ndi kuuma kwakukulu, kukana kukalamba, kukana kukwawa komanso moyo wautali wa ntchito.
10, tsinde la valavu ndi chitsulo chosungunula, kuuma kwa tsinde la valavu yosungunula, kukana kusweka, kukana kukwawa, kukana dzimbiri, komanso moyo wautali wautumiki.
✧ Ubwino wa Bonnet Yokhala ndi Valve ya BS 1873 Globe
Pakutsegula ndi kutseka valavu yachitsulo chopangidwa ndi chitsulo, chifukwa kukangana pakati pa diski ndi pamwamba pa valavu kumakhala kochepa kuposa kwa valavu ya chipata, sikutha kusweka.
Kutsekeka kapena kutseka kwa tsinde la valavu ndi kochepa, ndipo kuli ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valavu kumafanana ndi kutsekeka kwa diski ya valavu, ndikoyenera kwambiri kusintha kuchuluka kwa madzi. Chifukwa chake, valavu yamtunduwu ndi yoyenera kwambiri kudula kapena kulamulira ndi kugwedeza.
