Valavu ya Mpira Yolowera Yapamwamba
Kodi valavu ya mpira yolowera pamwamba ndi iti?
Ponena za kalembedwe ka thupi, ma valve a mpira nthawi zambiri amatha kugawidwa m'magulu awiri:valavu yolowera mbali ya mpira,valavu ya mpira yolowera pamwambandivalavu ya mpira yolumikizidwa kwathunthu.
Ma valve olowera pamwamba a mpira arMa valve omwe amasonkhanitsa mpira wake kuchokera mbali ya pamwamba. Ali ngati valavu yozungulira yomwe ili ndi thupi ndi boneti koma gawo lokongoletsa limagwiritsa ntchito mtundu wa mpira. Lili ndi thupi limodzi.Ma valve olowera pamwamba amagwiritsidwa ntchito m'machitidwe opachikira mapaipi pomwe pamwamba pa valve pakhoza kuchotsedwa kuti mulowe mpira ndi mipando popanda kuchotsa valve yonse kuchokera mumakina opachikira mapaipi.Ma valve a mpira olowera pamwamba nthawi zambiri amagwiritsidwa ntchito m'makina opangira zinthu komwe kukonza mkati mwa mzere kumakondedwa kuposa kuchotsa ma valve onse. Chifukwa chake, ndizofala kwambiri kugwiritsa ntchito ma valve a mpira olowera pamwamba pa kuthamanga kwambiri komwe kumafuna kukonza pafupipafupi monga ma valve a HIPPS (High Integrity Pressure Protection System) ndi zina zotero. Ubwino wa ma valve a mpira olowera pamwamba ndi kapangidwe kake komwe kamalola kulumikizana kochepa kwa ulusi kotero kuti kumachepetsanso njira yotulutsira madzi.
N'zotheka kuchotsa boniti yaValavu ya mpira yolowera pamwambakulola kulowa mosavuta m'bowo la thupi popanda kuchotsa valavu pamzere. Zida zapadera zokonzera zimalola kuchotsa mipira ndi mipando; ntchito yokonzayi imafuna malo ochepa kwambiri kuzungulira valavu, motero imalola kuti ikhale m'malo omwe malo ndi olepheretsa.
Kapangidwe ka mpira wolowera pamwambaImapezeka mu mawonekedwe opangidwa kapena opangidwa ndi chitsulo, thupi lofanana ndi chidutswa chimodzi lotsekedwa ndi bolnet yolumikizidwa ndi bolnet. Imaonetsetsa kuti ili ndi mphamvu zokwanira komanso kulimba pansi pa kuthamanga kwakukulu kogwira ntchito. Mtunduwu umaphatikizapo Full ndi Reduced bore, pressure ANSI class kuyambira 150 mpaka 1500, ndi kuphatikiza konse komwe kungatheke kwa ma ENDS connections: flanged (RF-RTJ), butt welding ndi HUB ends.
Zinthu zazikulu za valavu ya mpira yolowera pamwamba

- Tsinde losapsa ndi mphepo.
- Chisindikizo cha PTFE kapena graphite chokhala ndi kapu yolimba komanso mtundu wa koni.
- Cholumikizira cha thupi chomwe sichikhudzidwa ndi kupsinjika kwa mapaipi.
- Zitsogozo za tsinde mu chivundikiro ndi chigoba cha gland zimachotsa kugwedezeka kwa mbali. Flange yodzipangira yokha ndi gland yokhala ndi zidutswa ziwiri.
- Gasket ya thupi lopanda zitsulo yokhala ndi graphite yozungulira yokhala ndi mabala osapanga dzimbiri.
- Chotsukira chodzaza ndi madzi chimateteza ku gall ndipo chimapereka chisindikizo chachiwiri cha tsinde.
- ASME Gawo 8 kulumikizana kwa chivundikiro/chivundikiro cha thupi ndi bolt kumapereka kutseka kwakukulu kwa gasket ya thupi.
- Imalola kulowa pa intaneti kuti mpando usinthidwe.
- Ikhoza kulumikizidwa mu mzere popanda kusokoneza motsatira malangizo a Velan.
- Chokongoletsera chachitsulo chosapanga dzimbiri pa ma valve onse kuphatikizapo chogwirira.
- Zogwirira ndi chipangizo chotseka, komanso zowonjezera zomwe zilipo.
- Zipangizo zotsekera muyezo.
- Kugogoda kwa muyezo wa ma actuator oyika.
- Ma valve amatha kukwaniritsa zofunikira za NACE pa ntchito ya mpweya wowawasa ngati pakufunika.
- Moto unayesedwa motsatira API 607 Rev. 5/ISO 10497.

Kugwiritsa ntchito ma valve a mpira wolowera pamwamba
Ili ndi zabwino monga ntchito yabwino kwambiri yokonza pa intaneti, kukana madzi pang'ono, kapangidwe kosavuta, kusindikiza kodalirika, kugwiritsa ntchito bwino ndi kukonza, kugwira ntchito mwachangu, kutsegula ndi kutseka kosinthasintha, ndi zina zotero.
Mtundu uwu waValavu ya Mpira Yolowera Yapamwamba imagwiritsidwa ntchito kwambiri pakugwiritsa ntchito, kuyeretsa, ndi kunyamula mafuta, gasi ndi mchere. Ingagwiritsidwenso ntchito popanga mankhwala, mankhwala; njira yopangira magetsi amadzi, mphamvu ya kutentha ndi mphamvu ya nyukiliya; njira yotulutsira madzi, yomwe imagwiritsidwa ntchito kwambiri m'mapaipi ndi mafakitale. Makamaka pogwiritsira ntchito pamene kukonza pa intaneti kukufunika.
