Valavu ya Mpira vs Valavu ya Chipata: Kuyerekeza kwa Opanga

Ma valve a mafakitalendi ofunikira kwambiri powongolera kuyenda kwa madzi m'mapaipi, koma kusankha mtundu woyenera kumadalira kumvetsetsa mawonekedwe awo apadera. Ma valve awiri omwe amagwiritsidwa ntchito kwambiri—Valavu ya Mpira vs Valavu ya Chipata—amatumikira zolinga zosiyana. Nkhaniyi ikufotokoza matanthauzo awo, kapangidwe kawo, ntchito zawo, njira zoyenera zogwiritsira ntchito, opanga, ndi mitengo kuti akuthandizeni kupanga zisankho mwanzeru.

Ponena za ntchito zamafakitale, kusankha pakati paValavu ya mpira ndiValavu ya chipataNdikofunikira kwambiri kwa opanga. Mitundu yonse iwiri ya ma valve imagwira ntchito yofunika kwambiri powongolera kuyenda kwa madzi, koma ili ndi mawonekedwe osiyana omwe amawapangitsa kukhala oyenera pazochitika zosiyanasiyana. 

Matanthauzo: Kodi Ma Vavu a Mpira ndi Ma Vavu a Chipata ndi Chiyani? 

Ma Vavu a Mpira

Avalavu ya mpiraimagwiritsa ntchito mpira wozungulira wokhala ndi bore kuti ilamulire kuyenda kwa madzi. Chogwirira chikagwirizanitsa bore ndi payipi, valavu imatseguka; kuyizungulira madigiri 90 kumatseka kuyenda kwa madzi. Ma valve a mpira amadziwika kuti amagwira ntchito mwachangu komanso amatseka mwamphamvu.

Ma Valuvu a Chipata

Avalavu ya chipataimagwiritsa ntchito chipata chotsetsereka (chokhala ndi diski yosalala kapena yooneka ngati wedge) kuti iyambe kapena kuimitsa kuyenda kwa madzi. Chipatacho chimayenda molunjika ku mbali ya madzi, zomwe zimapangitsa kuti chikhale choyenera kuyatsa/kutseka koma chosayenerera kugwedezeka.

Kuyerekeza Kapangidwe: Kapangidwe ndi Zigawo

Kapangidwe ka Vavu ya Mpira

Thupi la Valavu ya Mpira:Yaing'ono, yokhala ndi malekezero opindika kapena opindika.

Valavu ya Mpira:Chipilala chozungulira chopanda kanthu (nthawi zambiri chitsulo chosapanga dzimbiri kapena mkuwa).

Mpando:Zisindikizo za PTFE kapena elastomeric zotsekera kuti zisatuluke madzi.

Tsinde:Amagwirizanitsa chogwirira ndi mpira kuti chizungulire.

Kapangidwe ka Valavu ya Chipata

Thupi:Yaikulu komanso yolemera, nthawi zambiri imakhala yopapatiza.

Geti:Chimbale chosalala kapena chooneka ngati wedge (chitsulo chosungunuka, bronze, kapena chitsulo chosapanga dzimbiri).

Tsinde:Amakweza kapena kutsitsa chipata pogwiritsa ntchito njira yolumikizidwa ndi ulusi.

Boneti:Zimateteza zigawo zamkati.

Kusiyana Kwakukulu:Ma valve a mpira ali ndi kapangidwe kosavuta komanso kosunga malo, pomwe ma valve a chipata ndi okulirapo koma ndi abwino kwambiri pamachitidwe opanikizika kwambiri. 

Ntchito: Milandu Yoyenera Yogwiritsira Ntchito 

Nthawi Yogwiritsira Ntchito Ma Valves a Mpira

Makampani:Mafuta ndi gasi, kukonza mankhwala, HVAC.

Zochitika:Kugwira ntchito pafupipafupi, kutseka mwamphamvu (monga mipiringidzo ya gasi), madzi owononga.

Nthawi Yogwiritsira Ntchito Ma Valves a Chipata

Makampani:Kukonza madzi, magetsi, migodi.

Zochitika:Kuyenda kwathunthu/kopanda zoletsa (monga mapaipi amadzi), kugwira ntchito kosachitika kawirikawiri.

Kuyerekeza kwa Wopanga: Mitundu Yotsogola 

Top Ball Vavu Opanga

1. Emerson (Fisher):Ma valve ogwira ntchito bwino kwambiri m'malo ovuta.

2. Kutumikira kwa Masika:Mapangidwe osinthika kuti agwiritsidwe ntchito m'mafakitale.

3. Ma Vavu a APOLLO:Malo okhala/malonda otchipa.

4. Ma Vavu a NSW: Wopanga Valavu ya Mpira Wogwira Ntchito kuchokera ku China

Opanga Valavu Yapamwamba ya Chipata

1. Velan:Ma valve olemera opangira magetsi.

2. Uinjiniya wa Ma Kreni:Zipangizo zosagwira dzimbiri.

3. Vavu ya NSWZaka 20 zaukadaulo mu Gate Valve Manufacture

4. AVK International:Mayankho a madzi ndi madzi otayira.

Kuyerekeza Mitengo: Ndalama Zoyambira ndi Zanthawi Yaitali 

Ma Vavu a Mpira:Mtengo wokwera wa pasadakhale (50–500+) chifukwa cha uinjiniya wolondola komanso zomatira. Mtengo wotsika wokonza pakapita nthawi.

Ma Valves a Chipata:Poyamba zimakhala zotsika mtengo (30–300+) koma zingafunike kusintha mipando/chipata nthawi zambiri.

Ndi Valavu Iti Yomwe Muyenera Kusankha 

Sankhani ma valve a mpirakuti igwire ntchito mwachangu, itseke bwino, komanso igwiritsidwe ntchito pafupipafupi.

Sankhani ma valve a chipatakwa makina amphamvu kwambiri omwe ali ndi malire ochepa a kayendedwe ka madzi.

Mwa kuwunika zinthu monga kuthamanga, mtundu wa madzi, ndi kuchuluka kwa momwe ntchito ikuyendera, mutha kusankha valavu yomwe ingakuthandizeni kwambiri kugwira ntchito bwino komanso kugwiritsa ntchito ndalama moyenera pa ntchito yanu.

Chidziwitso cha Wopanga Valve ya Mpira

Ma valve a mpira amadziwika kuti amagwira ntchito mwachangu komanso amatha kutseka bwino kwambiri.wopanga mavavu a mpiraKawirikawiri imagogomezera kuphweka kwa kapangidwe kake, komwe kumalola kuti pakhale kulamulira kosavuta kuyatsa/kutseka popanda kutsika kwambiri kwa mphamvu. Disiki yozungulira, kapena mpira, mkati mwa valavu imazungulira kuti ilole kapena kutsekereza kuyenda, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kuzimitsidwa mwachangu. Kuphatikiza apo, mavalavu a mpira ndi olimba kwambiri ndipo amatha kuthana ndi malo opanikizika kwambiri, zomwe zimapangitsa kuti akhale chisankho chabwino m'mafakitale monga mafuta ndi gasi, kukonza madzi, ndi kukonza mankhwala.

Zoganizira za Wopanga Ma Valavu a Chipata

Kumbali inayi, ma valve a chipata amapangidwira makamaka kuti azigwiritsidwa ntchito mokwanira.wopanga ma valavu a chipatanthawi zambiri zimawonetsa luso la valavu yopereka kuyenda kolunjika popanda kukana kwambiri. Mosiyana ndi mavalavu a mpira, mavalavu a chipata sali oyenera kugwiritsidwa ntchito popondereza, chifukwa amatha kuyambitsa kugwedezeka ndi kuwonongeka. Komabe, amagwira ntchito bwino kwambiri pamene kutsekedwa kwathunthu ndikofunikira, monga m'mapaipi ndi machitidwe akuluakulu amadzi. Njira yogwirira chipata imalola kutseka kolimba, kuteteza kutuluka kwa madzi akatsekedwa kwathunthu.

Mapeto

Kusankha pakati pavalavu ya mpira vs valavu ya chipatakutengera zofunikira za ntchitoyo. Ma valve a mpira ndi abwino kwambiri pozimitsa mwachangu komanso pamavuto amphamvu, pomwe ma valve a chipata ndi oyenera kwambiri pa ntchito zomwe sizikufuna kukana kuyenda bwino. Opanga ayenera kuganizira mosamala zinthu izi posankha mtundu woyenera wa valve pa ntchito zawo, kuonetsetsa kuti machitidwe awo amagwira ntchito bwino komanso odalirika.
