Mukasankha valavu yoyenera ya mapaipi a mafakitale, ulimi, kapena malonda, kumvetsetsa kusiyana pakati pamavavu a gulugufendimavavu awiri a gulugufe a flangendikofunikira. Ma valve onsewa amagwiritsidwa ntchito kwambiri pochiza madzi, kukonza mankhwala, HVAC, ndi mafakitale amafuta ndi gasi chifukwa cha kapangidwe kake kakang'ono, kugwiritsa ntchito bwino ndalama, komanso kuwongolera bwino kayendedwe ka madzi. Komabe, kapangidwe kake, njira zoyikira, ndi zochitika zogwiritsira ntchito zimasiyana, zomwe zimapangitsa kuti chilichonse chikhale choyenera mikhalidwe inayake. Nkhaniyi ikufotokoza kusiyana kwakukulu, ubwino, kuipa, ndi kugwiritsa ntchito ma valve a gulugufe a lug ndi double flange kuti akutsogolereni pakupanga zisankho.
1. Valavu ya Gulugufe: Kapangidwe ndi Zinthu Zake
Ma valve a gulugufe a Lug amadziwika ndi zoyikapo ulusi, kapena "ma lug," pa thupi la valavu, zomwe zimalola kuyika bolt mwachindunji ku ma flange a mapaipi. Kapangidwe kameneka kamagwiritsa ntchito ma seti awiri a mabolt odziyimira pawokha opanda mtedza, chifukwa mabolt amalowa mwachindunji m'ma lug. Kapangidwe kotereku ndi kabwino kwambiri pa ntchito zomaliza, pomwe mbali imodzi ya payipi imatha kudulidwa popanda kukhudza inayo.
Zinthu Zofunika Kwambiri pa Ma Valves a Lug Butterfly
- Ma Lugs Okhala ndi Ulusi: Ma Lugs amapereka malo olimba oikira, zomwe zimathandiza kuti valavu ikhale yolumikizidwa payokha ku flange iliyonse ya chitoliro.
- Kapangidwe Kakang'ono: Kopepuka komanso kakafupi, ma valve a lug amasunga malo, oyenera makina omwe ali ndi malo ochepa.
- Kuyenda kwa Maulendo Awiri: Ma valve ofewa otsekedwa amathandizira kuyenda kwa magetsi mbali zonse ziwiri, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito.
- Kukonza Mosavuta: Kapangidwe ka lug kamalola mbali imodzi ya payipi kuchotsedwa kuti ikonzedwe popanda kukhudza inayo.
- Kuyeza kwa Kupanikizika: Kawirikawiri kumagwiritsidwa ntchito pakugwiritsa ntchito mphamvu zochepa mpaka zapakati, ngakhale kuti kuyeza kwa kupanikizika kungachepe mu ntchito yomaliza.
- Kusinthasintha kwa Zinthu: Kumapezeka mu zipangizo monga chitsulo chosungunuka, WCB, kapena chitsulo chosapanga dzimbiri, ndi mipando monga EPDM kapena PTFE yolimbana ndi mankhwala.
2. Valavu ya Gulugufe ya Flange Yawiri: Kapangidwe ndi Zinthu Zake
Ma valve a gulugufe awiri okhala ndi ma flange ophatikizika mbali zonse ziwiri za thupi la valavu, omangiriridwa mwachindunji ku ma flange ofanana a mapaipi. Kapangidwe kameneka kamatsimikizira kulumikizana kosatayikira, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamphamvu kwambiri komanso m'mimba mwake waukulu. Kapangidwe kake kolimba kamapirira mphamvu zazikulu.
Zinthu Zofunika Kwambiri pa Ma Valves a Gulugufe a Flange Awiri
- Ma Flange Ogwirizana: Ma Flange onse awiri amalumikizana ndi ma flange a mapaipi kudzera m'mabolt, zomwe zimapangitsa kuti zigwirizane bwino.
- Kapangidwe Kolimba: Kopangidwa ndi zinthu zolimba monga WCB, chitsulo chosungunuka, kapena chitsulo chosapanga dzimbiri.
- Kutseka Kwapamwamba: Kapangidwe ka Flange kamatsimikizira kutseka kolimba, kuchepetsa zoopsa zotuluka pakugwiritsa ntchito kofunikira.
- Kuyenda kwa Magawo Awiri: Monga ma valve a lug, ma valve a flange awiri amathandizira kuyenda mbali zonse ziwiri.
- Chimake chachikulu: Chimakwanira mainchesi akuluakulu poyerekeza ndi ma valve a lug.
3. Valavu ya Gulugufe ya Lug vs. Valavu ya Gulugufe ya Flange Yawiri
Kuti musankhe mwanzeru, kumvetsetsa kusiyana kwakukulu pakati pa mavavu a gulugufe a lug ndi mavavu a gulugufe a double flange ndikofunikira kwambiri. Pansipa pali kufananiza mwatsatanetsatane kwa zinthu zofunika:
3.1 Zinthu Zofanana
- Kusinthasintha kwa Kuyika: Zonse ziwiri zimalola kuti mbali imodzi ya payipi idulidwe popanda kukhudza inayo, yoyenera machitidwe omwe amafunika kukonza pafupipafupi kapena kulekanitsidwa ndi gawo.
- Mtengo Poyerekeza ndi Ma Wafer Valve: Chifukwa cha ma threaded lugs kapena dual flanges, onse ndi okwera mtengo kuposa ma wafer valves.
- Makhalidwe Ogawana:
- Thandizo la Mayendedwe Awiri: Mitundu yonse iwiri ya ma valve imalola kuyenda kwa madzi mbali iliyonse, yoyenera machitidwe okhala ndi mayendedwe osiyanasiyana amadzimadzi.
- Kusiyanasiyana kwa Zinthu: Zonsezi zitha kupangidwa kuchokera ku zinthu zofanana monga chitsulo cha kaboni, chitsulo chosungunuka, kapena chitsulo chosapanga dzimbiri, ndi mipando yosiyana (monga EPDM kapena PTFE) yopangidwa ndi madzi monga madzi, mankhwala, kapena mpweya.
3.2 Kusiyana Kofunika Kwambiri
3.2.1 Njira Yokhazikitsira
- Valavu ya Gulugufe ya Lug: Imagwiritsa ntchito maboluti a mutu umodzi kuti ilumikizane ndi ma flange a mapaipi. Ma boluti opangidwa ndi ulusi amalola maboluti awiri kuti ateteze valavuyo popanda nati, zomwe zimathandiza kuti ntchito yomaliza ikhale yosavuta komanso yosamalidwa.
- Valavu ya Gulugufe ya Flange Yawiri: Ili ndi ma flange olumikizidwa mbali zonse ziwiri, zomwe zimafuna kulumikizidwa ndi ma flange a mapaipi ndi bolt. Izi zimathandizira kulumikizana kolimba koma zimapangitsa kuti kukonza kukhale kovuta.
3.2.2 Kusinthasintha kwa Kukhazikitsa
- Valavu ya Gulugufe ya Lug: Imapereka kusinthasintha kwakukulu, chifukwa mbali imodzi imatha kulumikizidwa popanda kukhudza inayo, yoyenera makina omwe amafunika kukonzedwa kapena kusinthidwa pafupipafupi.
- Valavu ya Gulugufe ya Flange Yawiri: Imafuna kulumikizidwa ndi kulumikizidwa mbali zonse ziwiri, zomwe zimapangitsa kuti kukhazikitsa ndi kuchotsa kutenge nthawi. Imapereka kusinthasintha kochepa kosamalira koma kulumikizana kotetezeka kwambiri.
3.2.3 Ma diameter Oyenera
- Valavu ya Gulugufe ya Lug: Nthawi zambiri imayambira pa DN50 mpaka DN600.Mavavu a flange amodziikhoza kukhala njira ina m'malo mwa makina ocheperako malo.
- Valavu ya Gulugufe ya Flange Yawiri: Imayambira pa DN50 mpaka DN1800. Pa mainchesi akuluakulu, mayankho apadera amapezeka mukawapempha.
3.2.4 Mtengo ndi Kulemera
- Valavu ya Gulugufe: Yotsika mtengo kwambiri chifukwa cha kapangidwe kake kopepuka, zomwe zimachepetsa ndalama zoyikira.
- Valavu ya Gulugufe ya Flange Yawiri: Yolemera komanso yokwera mtengo chifukwa cha ma flange ophatikizika ndi zinthu zina zowonjezera. Mavavu a flange awiri akuluakulu angafunike thandizo lowonjezera chifukwa cha kulemera kwawo.
3.2.5 Kukonza ndi Kuchotsa Katundu
- Valavu ya Gulugufe ya Lug: Yosavuta kusokoneza ndi kusamalira, chifukwa mbali imodzi imatha kuchotsedwa popanda kukhudza inayo.
- Valavu ya Gulugufe ya Flange Yawiri: Imafuna ntchito yambiri kuti ichotsedwe chifukwa cha mabolts ambiri komanso zofunikira pakuyikonza molondola.

Kusankha pakati pa chosindikizidwa chofewavalavu ya gulugufendivavu ya gulugufe ya flange iwiriZimadalira zosowa za makina anu. Ma valve a gulugufe a Lug ndi abwino kwambiri pa ntchito zomwe zimafuna kukonzedwa pafupipafupi komanso kuyikidwa pang'ono. Ma valve a gulugufe a double flange, omwe ali ndi kutseka kwawo kolimba, ndi oyenera kwambiri mapaipi akuluakulu komanso ntchito zofunika kwambiri. Poyesa zinthu monga kuthamanga, kukonza, malo, ndi bajeti, mutha kusankha valve yomwe imakonza magwiridwe antchito komanso kugwiritsa ntchito bwino ndalama.
