Kodi Valavu ya Chipata ndi Chiyani? Tanthauzo, Kapangidwe, Mitundu, ndi Chidziwitso cha Wopereka
Chiyambi
Valavu ya chipataNdi gawo lofunika kwambiri m'machitidwe opangira mapaipi a mafakitale, opangidwa kuti azilamulira kuyenda kwa madzi. Ma valve a zipata amadziwika kuti ndi odalirika komanso osavuta kugwiritsa ntchito, chifukwa amagwiritsidwa ntchito kwambiri m'mafakitale opereka madzi, mafuta ndi gasi, komanso mankhwala. M'nkhaniyi, tifufuza tanthauzo, kapangidwe kake, ntchito, magulu, zipangizo, njira zolumikizira, ndi mitengo ya ma valve a zipata, poyerekeza mayiko akuluakulu opanga zinthu monga China, USA, ndi Germany.
Kodi Valavu ya Chipata ndi Chiyani?
A valavu ya chipatandi valavu yoyenda molunjika yomwe imagwiritsa ntchito chipata chosalala kapena chooneka ngati wedge kuyambitsa kapena kuletsa kuyenda kwa madzi. Ikatsegulidwa kwathunthu, imalola kuyenda kosalekeza, ndipo ikatsekedwa, imapereka chisindikizo cholimba. Kapangidwe kake kosavuta kamapangitsa kuti ikhale yoyenera kugwiritsa ntchito poyatsa/kutseka m'malo molamulira kuyenda kwa madzi.
Kapangidwe ka Valavu ya Chipata
Valavu yodziwika bwino ya chipata imakhala ndi:
1. Thupi: Imasunga zinthu zamkati ndipo imalumikizana ndi payipi.
2. Chipata/Mphepete: Disiki yosunthika yomwe imatseka kapena kulola kuyenda.
3. Tsinde: Imalumikiza gudumu lamanja kapena choyeretsera magetsi ku chipata.
4. Boneti: Imaphimba tsinde ndi thupi, kuonetsetsa kuti madzi salowa.
5. MipandoMalo omwe chipata chimatsekeredwa akatsekedwa.
Ntchito za Ma Valves a Chipata
- Kuwongolera Kutsegula/Kutseka: Amagwiritsidwa ntchito makamaka kutsegula kapena kutseka mapaipi kwathunthu.
- Kukana Kutsika kwa Mayendedwe: Kutsika kochepa kwa mphamvu ya mpweya ikatsegulidwa kwathunthu.
- Kuyenda kwa Mayendedwe Awiri: Yoyenera kugwiritsa ntchito zomwe zimafuna kuyenda mbali zonse ziwiri.
Magulu a Ma Valavu a Chipata
Ma valve a zipata amagawidwa m'magulu motere:
1. Kapangidwe ka Chipata:
–Valavu ya Chipata cha Wedge: Kwa makina amphamvu kwambiri.
–Valavu ya Chipata Chofanana Chofanana: Yabwino kwambiri pa nthunzi kapena mpweya.
2. Mtundu wa Tsinde:
–Tsinde Lokwera: Kusuntha kwa tsinde kooneka kumasonyeza malo a valavu.
–Tsinde LosakweraKapangidwe kakang'ono ka malo ochepa.
Zipangizo Zofala
Kusankha zinthu kumakhudza kulimba ndi kugwiritsa ntchito:
- Chitsulo Choponyedwa: Yotsika mtengo pamakina amadzi opanda mphamvu zambiri.
- Chitsulo chosapanga dzimbiri: Imalimbana ndi dzimbiri m'malo okhala ndi mankhwala kapena m'nyanja.
- Chitsulo cha Kaboni: Yoyenera mapaipi amafuta/gasi otentha kwambiri.
- Mkuwa: Amagwiritsidwa ntchito m'makina a m'nyanja ndi a HVAC.
Njira Zolumikizirana
Ma valve a chipata amalumikizidwa ku mapaipi kudzera mu:
1. Malekezero Ozungulira: Za makina a mafakitale amphamvu kwambiri.
2. Mapeto Okhala ndi Ulusi: Chofala kwambiri m'mapaipi ang'onoang'ono.
3. Mapeto Osefedwa: Imapereka magwiridwe antchito osataya madzi m'magwiritsidwe ntchito ofunikira.
Zinthu Zokhudza Mitengo ya Valavu ya Chipata
ThemtengoKuchuluka kwa valavu ya chipata kumadalira pa:
- Kukula ndi KupanikizikaMa valve akuluakulu kapena magulu amphamvu kwambiri amawononga ndalama zambiri.
- Zinthu ZofunikaMa valve achitsulo chosapanga dzimbiri ndi okwera mtengo kuposa chitsulo chopangidwa ndi chitsulo.
- Mtundu ndi WogulitsaOpanga odziwika bwino akhoza kulipiritsa ndalama zambiri.
Pa avareji, mitengo imayambira pa$5 pa ma valve ang'onoang'ono achitsulo chopangidwa ndi chitsuloku$1,000+ pa ma valve akuluakulu achitsulo chosapanga dzimbiri.
Mayiko Akuluakulu Opanga: China vs. Ogulitsa Padziko Lonse
1. China:
- Ikulamulira kupanga padziko lonse lapansi ndiyotsika mtengomayankho.
- Nyumba zambirimafakitalendiopangakupereka maoda ambiri.
- Mpikisanomitengopopanda kusokoneza khalidwe (monga, miyezo ya ASTM/API).
2. USA ndi Germany:
- Amadziwika ndi ma valve olondola kwambiri koma pamtengo wokwera.
- Amakonda kwambiri mafakitale apadera monga nyukiliya kapena ndege.
3. India:
- Ikuoneka ngati njira ina yosawononga ndalama zambiri m'malo mwa China.
Chifukwa Chosankha Ogulitsa aku China
- Ma MOQ Otsika: Yabwino kwambiri kwa mabizinesi ang'onoang'ono mpaka apakatikati.
- KusinthaMafakitale ambiri **amafakitale** amapereka mapangidwe okonzedwa mwaluso.
- Kutumiza Mwachangu: Ma network olimba a zinthu zoyendera.
Mapeto
Ma valve a pachipata ndi ofunikira kwambiri pakuwongolera madzi m'mafakitale osiyanasiyana. Kumvetsetsa kapangidwe kake, zipangizo zake, ndi mitengo yake kumathandiza kusankha valve yoyenera zosowa zanu. Mukamagula zinthu, ganizirani kugwirizana ndi kampani yodalirika.wogulitsakapenawopangamuChinakuti muyeze bwino khalidwe ndi mtengo wake. Ndi zapamwambamafakitalendi mpikisanomitengo, China ikadali chisankho chabwino kwambiri pakugula ma valve a pachipata.
