Kodi ndi chiyaniVavu ya Mpira Waing'ono

A valavu yaying'ono ya mpirandi valavu yozungulira kotala yomwe imagwiritsa ntchito mpira wopanda kanthu, wobowoka kuti ilamulire kuyenda kwa madzi. Chogwirira cha valavu chikazunguliridwa madigiri 90, mpirawo umazungulira kuti ugwirizane ndi chitoliro chake ndi payipi (malo otseguka) kapena kuutsekereza kwathunthu (malo otsekedwa). Mavalavu amenewa amadziwika ndi kukula kwawo kochepa, kapangidwe kopepuka, komanso kosavuta kugwiritsa ntchito, zomwe zimapangitsa kuti akhale abwino kwambiri pamalo opapatiza kapena kugwiritsa ntchito komwe kumafuna kusintha pafupipafupi.

Ubwino waukulu wa ma valve ang'onoang'ono a mpira ndi awa:

- Kutseka kosataya madzikuti ntchito yake ikhale yodalirika.
- Kutseka mwachangundi mphamvu yochepa.
- Kusinthasinthapogwira ntchito zamadzimadzi, mpweya, ndi zinthu zowononga.
- Kusamalira kochepachifukwa cha kapangidwe kosavuta.

Mitundu ya Ma Vavu Ang'onoang'ono a Mpira

Ma valve ang'onoang'ono a mpira amapezeka m'mapangidwe osiyanasiyana kuti agwirizane ndi ntchito zinazake. Nazi mitundu yodziwika kwambiri:

1. Valavu ya Mpira wa Ulusi

A valavu ya mpira wa ulusiIli ndi malekezero okhala ndi ulusi (NPT, BSPP, kapena BSPT) kuti ikhale yosavuta kuyika m'mapaipi popanda kuwotcherera. Ma valve awa amagwiritsidwa ntchito kwambiri m'mapayipi okhala m'nyumba, makina oponderezedwa mpweya, komanso m'mafakitale okhala ndi mphamvu yochepa.

2. Valavu ya Mpira wa Flange

Ma valve a mpira wa FlangeAli ndi malekezero opindika kuti azitha kulumikizana ndi maboliti, abwino kwambiri pamakina amphamvu kwambiri kapena akuluakulu. Amapezeka kwambiri m'mafakitale amafuta ndi gasi, kuyeretsa madzi, komanso mankhwala.

3. Valavu ya Mpira ya PC ziwiri motsutsana ndi Valavu ya Mpira ya PC zitatu

- Ma valve awiri a mpira wa PCZili ndi ziwalo ziwiri zazikulu, zomwe zimapereka mgwirizano pakati pa mtengo ndi kuthekera kogwirira ntchito.
- Ma valve atatu a mpira wa PCIli ndi magawo atatu a thupi omwe amatha kulekanitsidwa, zomwe zimathandiza kuti zisamavulidwe mosavuta kuti ziyeretsedwe kapena kukonzedwa popanda kuchotsa valavu paipi.

4. Valavu Yoyandama ya Mpira

Muvalavu ya mpira yoyandama, mpirawo umagwira ntchito m'malo mwake poukakamiza kuchokera ku mipando ya valavu. Kapangidwe kameneka ndi kotsika mtengo ndipo ndi koyenera kugwiritsidwa ntchito pa kupanikizika kochepa mpaka pakati.

Zosankha Zazinthu Za Ma Valves Ang'onoang'ono a Mpira

Zipangizo za valavu zimakhudza kulimba kwake, kukana dzimbiri, komanso kugwirizana ndi madzi. Zosankha zodziwika bwino ndi izi:

1. Valavu ya Mpira Wosapanga Chitsulo Chosapanga Chitsulo

Ma valve a mpira osapanga dzimbiri(monga SS304, SS316) amachita bwino kwambiri m'malo owononga zinthu, monga kukonza mankhwala, kugwiritsa ntchito zinthu zam'madzi, kapena machitidwe oyesera chakudya.

2. Valavu ya Mpira wa Chitsulo cha Carbon

Ma valve a mpira wa chitsulo cha kabonindi olimba komanso otchipa, abwino kwambiri pamakina otentha kwambiri komanso opanikizika kwambiri m'mafakitale opangira mafuta kapena m'mafakitale opangira magetsi.

3. Valavu ya Mpira Yopangidwa ndi Chitsulo

Ma valve a mpira wachitsulo opangidwaAmapangidwa pogwiritsa ntchito forging, zomwe zimapangitsa kuti akhale olimba kwambiri komanso opirira ku zovuta kwambiri. Amagwiritsidwa ntchito kwambiri m'mafakitale akuluakulu.

Kugwiritsa Ntchito Ma Vavu Ang'onoang'ono a Mpira

- Mapaipi ndi HVAC: Kulamulira kayendedwe ka madzi m'nyumba kapena m'mabizinesi.
- Kukonza Mankhwala: Kugwira madzi amphamvu pogwiritsa ntchito chitsulo chosapanga dzimbiri kapena ma valve okhala ndi PTFE.
- Magalimoto: Kuwongolera mafuta ndi zoziziritsira m'makina ang'onoang'ono a injini.
- Mankhwala: Kuonetsetsa kuti madzi oyeretsedwa ndi ma valve a mpira waukhondo amasamutsidwa.
- Ulimi: Kuthirira ndi kugawa feteleza.

Momwe Mungasankhire Valavu Yaing'ono Yabwino Ya Mpira

1. Kuchuluka kwa Kupanikizika ndi Kutentha: Onetsetsani kuti valavu ikukwaniritsa malire a ntchito ya dongosolo lanu.
2. Mtundu WolumikiziraSankhani malekezero okhala ndi ulusi, flange, kapena welded kutengera zofunikira pakuyika.
3. Kugwirizana kwa Zinthu: Gwirizanitsani thupi la valavu ndi zinthu zomangira ndi mtundu wamadzimadzi (monga, zomangira za PTFE za mankhwala).
4. Kukula kwa VavuTsimikizani kuti kukula kwa doko (monga, ¼” mpaka 2”) kukugwirizana ndi kukula kwa payipi yanu.
5. ZiphasoYang'anani miyezo yamakampani monga API, ANSI, kapena ISO kuti mutsimikizire khalidwe.

Mafunso Ofunsidwa Kawirikawiri Zokhudza Ma Vavu Ang'onoang'ono a Mpira

Q: Kodi pali kusiyana kotani pakati pa valavu ya mpira yaying'ono ndi valavu ya mpira wamba?

A: Mavavu a mpira waung'onoNdi zazing'ono kukula (nthawi zambiri zimakhala pansi pa mainchesi 1) ndipo zimapangidwa kuti zigwiritsidwe ntchito mopanda madzi kapena molondola, pomwe ma valve wamba amagwirira ntchito machitidwe akuluakulu.

Q: Kodi valavu yachitsulo chosapanga dzimbiri ingagwire madzi a m'nyanja?

A: Inde, ma valve achitsulo chosapanga dzimbiri a SS316 amapereka chitetezo chabwino kwambiri cha dzimbiri m'malo okhala m'nyanja.

Q: Ndi liti pamene ndiyenera kusankha valavu ya mpira ya ma PC atatu m'malo mwa kapangidwe ka ma PC awiri

A: SankhaniValavu ya mpira ya ma PC atatungati pakufunika kukonza kapena kuyeretsa pafupipafupi, chifukwa zimathandiza kuti zinthu zamkati zilowe mosavuta.
