Ma valve a chipataNdi zinthu zofunika kwambiri m'mafakitale ndi m'nyumba zosungira mapaipi, zomwe zimapangidwa kuti ziwongolere kuyenda kwa madzi kapena mpweya. Amadziwika kuti ndi odalirika komanso osavuta kugwiritsa ntchito, amachita gawo lofunikira kwambiri pakugwiritsa ntchito komwe kumafuna kuyenda kwathunthu kapena kuzimitsidwa kwathunthu. M'nkhaniyi, tifufuza tanthauzo la valavu ya chipata, momwe imagwirira ntchito, ubwino wake, njira zabwino zosamalira, komanso momwe imasiyanirana ndi mitundu ina ya mavalavu monga mavalavu a globe, mavalavu a mpira, ndi mavalavu owunikira.
Kodi Valavu ya Chipata N'chiyani?
A valavu ya chipatandi valavu yoyenda molunjika yomwe imagwiritsa ntchito "chipata" chathyathyathya kapena chooneka ngati wedge (diski) kuti iyambe kapena kuyimitsa kuyenda kwa madzi. Chipatacho chimayenda molunjika ku mbali ya madzi, mwina kutsegula kwathunthu njira kuti madzi aziyenda mopanda malire kapena kutseka mwamphamvu kuti atseke cholumikiziracho. Mavalavu a chipata nthawi zambiri amagwiritsidwa ntchito m'makina omwe kupanikizika kochepa komanso kugwira ntchito kosachitika kawirikawiri sikofunikira, monga m'mapaipi operekera madzi, mafakitale amafuta ndi gasi, ndi machitidwe a HVAC.
Kodi Valavu ya Chipata Imagwira Ntchito Bwanji?
Kugwira ntchito kwa valavu ya chipata kumadalira njira yosavuta koma yothandiza:
1. Kutsegula Valavu: Pamene gudumu lamanja kapena choyendetsera magetsi chatembenuzidwa motsutsana ndi wotchi, chipatacho chimakwera mmwamba kudzera mu tsinde lokhala ndi ulusi, zomwe zimapangitsa kuti madziwo asatseguke bwino.
2. Kutseka Valavu: Kutembenuza gudumu lamanja mozungulira wotchi kumatsitsa chipata mpaka chitakhala molimba motsutsana ndi thupi la valavu, zomwe zimapangitsa kuti chitseko chikhale cholimba ndikuletsa kuyenda kwa madzi.
Ma valve a chipata amapangidwirakutsegula kwathunthu kapena kutseka kwathunthuKugwiritsa ntchito, zomwe zimapangitsa kuti zisagwiritsidwe ntchito bwino (kuchepetsa pang'ono kuyenda kwa madzi). Kuyenda kwawo kolunjika kumatsimikizira kuti kugwedezeka kochepa komanso kutayika kwa mphamvu yamagetsi kumawoneka kochepa akatsegulidwa kwathunthu.
Ubwino wa Ma Valves a Chipata
- Kutseka Molimba: Imapereka kutseka kwabwino kwambiri, kuteteza kutuluka kwa madzi m'malo otsekedwa.
- Kutsika Kochepa kwa KupanikizikaKapangidwe kake ka full-bore kamachepetsa kukana kwake kakatsegulidwa kwathunthu.
- KulimbaKapangidwe kolimba kamayenera malo omwe ali ndi mphamvu yamagetsi komanso kutentha kwambiri.
- Kuyenda kwa Mayendedwe Awiri: Imatha kuyendetsa kayendedwe ka madzi mbali iliyonse.
- Kapangidwe Kosavuta: Yosavuta kugwiritsa ntchito ndi kusamalira.
Malangizo Okonza Ma Valuvu a Chipata
Kusamalira bwino kumawonjezera moyo wa ma valve a chipata:
1. Kuyang'anira Nthawi Zonse: Yang'anani ngati pali dzimbiri, kutuluka kwa madzi, kapena kuwonongeka kwa tsinde.
2. Kupaka mafuta: Pakani mafuta pa ulusi wa tsinde kuti muwonetsetse kuti ntchito ikuyenda bwino.
3. KuyeretsaChotsani zinyalala kuchokera ku thupi la valavu ndi chipata kuti mupewe kutsekeka.
4. Kusintha Chisindikizo: Sinthani zomatira kapena zomangira zomwe zatha ntchito kuti zisamatuluke.
5. Pewani Kulimbitsa Mopitirira MuyesoMphamvu yochulukirapo ingawononge chipata kapena mpando.
Valavu ya Chipata vs. Valavu ya Globe vs. Valavu ya Mpira vs. Valavu Yoyang'anira
1. Valavu ya Chipata vs. Valavu ya Globe
- NtchitoMa valve a pachipata ndi owongolera kuyatsa/kutseka; ma valve a globe amawongolera kayendedwe ka madzi.
- KapangidweMa valve ozungulira ali ndi thupi lovuta looneka ngati Z lothandizira kupondaponda, pomwe ma valve olowera ali ndi thupi lolunjika bwino.
- Kutsika kwa KupanikizikaMa valve ozungulira amachititsa kuti kuthamanga kwa mpweya kuchepe kwambiri akatsegulidwa pang'ono.
2. Valavu ya Chipata vs. Valavu ya Mpira
- Ntchito: Ma valve a mpiraGwiritsani ntchito mpira wozungulira wokhala ndi bore kuti mutseke mwachangu; ma valve a chipata amagwiritsa ntchito kuyenda kolunjika.
- LiwiroMa valve a mpira amagwira ntchito mwachangu koma amatha kutha msanga akagwiritsidwa ntchito pafupipafupi.
3. Valavu ya Chipata vs. Valavu Yowunikira
- Malangizo a Kuyenda: Onetsetsani kuti ma valve amalola kuyenda mbali imodzi yokha; ma valve a chipata ndi a mbali ziwiri.
- Zokha zokha: Onetsetsani kuti ma valve akugwira ntchito okha, pomwe ma valve a chipata amafunika kuyendetsedwa ndi manja kapena ndi actuator.
Mapeto
Ma valve a pachipata ndi ofunikira kwambiri pamakina omwe amafuna kutsekedwa kodalirika komanso kukana kochepa. Kumvetsetsa momwe amagwirira ntchito, ubwino wake, ndi zosowa zake zosamalira kumatsimikizira kuti amagwira ntchito bwino kwambiri. Ngakhale kuti amasiyana ndi ma valve ozungulira, ozungulira, komanso owunikira kapangidwe ndi ntchito, kusankha valve yoyenera kumadalira zomwe makina anu akufuna. Kuti mugwire bwino ntchito kwa nthawi yayitali, ganizirani bwino nthawi zonse ndi kukonza nthawi yake.
Mwa kudziwa bwino zoyambira za ma valve a zipata, mutha kupanga zisankho zodziwikiratu za ntchito zamafakitale, zamalonda, kapena nyumba.
