1. Tanthauzo Loyambira ndi Kapangidwe
Vavu yofewa yotsekera ya gulugufe yozungulira (yomwe imadziwikanso kuti "valavu ya gulugufe yapakati") ndi valavu yozungulira yozungulira yozungulira kotala yomwe imapangidwira kuyatsa/kutseka kapena kuletsa kuyenda kwa madzi m'mapaipi. Zinthu zake zazikulu ndi izi:
Kapangidwe Kozungulira: Chitsinde cha valavu, diski, ndi mpando zili pamalo ofanana pakati, zomwe zimapangitsa kuti zikhale zosavuta komanso zazing'ono.
Njira Yotsekera Yofewa: Chisindikizo chofewa cha elastomeric (monga rabara, EPDM, NBR) chimalumikizidwa mu thupi la valavu kapena mpando, zomwe zimapangitsa kuti chisindikizocho chikhale cholimba kuti chisatuluke.
Malekezero Opindika: Vavu ili ndi maulumikizidwe opindika, zomwe zimathandiza kuti pakhale kuyika kosavuta pa mapaipi ogwirizana ndi miyezo monga ANSI, DIN, kapena JIS.
2.Zigawo Zofunika
3. Mfundo Yogwirira Ntchito
Malo Otseguka: Diski imazungulira 90° kuti igwirizane ndi njira yoyendera, kuchepetsa kutsika kwa kuthamanga kwa magazi ndikulola kuyenda kwathunthu.
Malo Otsekedwa: Disiki imazungulira kumbuyo kuti ikanikizidwe motsutsana ndi chisindikizo chofewa, zomwe zimapangitsa kuti ikhale yotseka kwambiri. Kapangidwe kake kamadalira kusintha kwa chisindikizo kuti chitseke, zomwe zimapangitsa kuti chikhale chothandiza kwambiri pakugwiritsa ntchito mphamvu zochepa.
4. Zinthu Zofunika Kwambiri ndi Ubwino
Kutseka Kolimba: Zisindikizo zofewa zimapereka kukana kotuluka madzi bwino, nthawi zambiri zimakwaniritsa miyezo yolimba ngati thovu (monga, ANSI B16.104 Class VI, ISO 15848-1).
Kugwiritsa Ntchito Mphamvu Yochepa: Kapangidwe kake kozungulira komanso chisindikizo chosinthasintha chimachepetsa kukangana, zomwe zimapangitsa kuti ntchito yamanja ikhale yosavuta kapena kugwiritsidwa ntchito ndi ma actuator opepuka.
Yaing'ono komanso Yopepuka: Poyerekeza ndi ma valve a chipata kapena a globe, ma valve a gulugufe ozungulira ndi ang'onoang'ono komanso osavuta kuwayika m'malo ochepa.
Yotsika Mtengo: Kapangidwe kosavuta komanso kugwiritsa ntchito zinthu zochepa kumapangitsa kuti zikhale zotsika mtengo pazofunikira zoyendetsera kayendedwe ka madzi.
Kugwirizana kwa Zida Zosiyanasiyana: Koyenera madzi, mpweya, mafuta, zakumwa zosawononga, ndi zida zopyapyala (zokhala ndi zokutira zosapsa).
5. Mafotokozedwe Aukadaulo
Kuchuluka kwa Kupanikizika: Kupanikizika kotsika mpaka kwapakati (monga PN6)–PN16 / Kalasi 125–Kalasi 150).
Kuchuluka kwa Kutentha:
Ma elastomer okhazikika (monga, NR, EPDM): -10°C mpaka 90°C (14)°F mpaka 194°F).
Zisindikizo zotentha kwambiri (monga Viton®, PTFE): -20°C mpaka 150°C (-4)°F mpaka 302°F).
Kutsatira Miyezo:
Kapangidwe: EN593, API 609, MSS SP-67.
Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Kuyesa: API 598, (mayeso otayira madzi).
6. Mapulogalamu
Ma valve a gulugufe otsekedwa bwino okhala ndi flange D341X-16Qamagwiritsidwa ntchito kwambiri mu:
Kupereka Madzi ndi Kutulutsa Madzi: Makina amadzi a m'matauni, malo oyeretsera zinyalala, ndi maukonde othirira.
Machitidwe a HVAC: Kulamulira mpweya, madzi, kapena nthunzi pakutenthetsa, mpweya wabwino, ndi mpweya woziziritsa.
Makampani Ogulitsa Zakudya ndi Zakumwa: Kugwiritsa ntchito ukhondo ndi zomatira zovomerezeka ndi FDA (monga EPDM yokhala ndi zokutira zamtundu wa chakudya).
Njira Zonse Zamakampani: Kusamalira madzi osawononga m'mafakitale a mankhwala, mapepala, ndi mankhwala (kwa zofalitsa zofatsa zokha).
Kumanga Sitima Zapamadzi ndi Zombo: Kuwongolera kuyatsa/kuzima m'madzi a m'nyanja kapena machitidwe a ballast (okhala ndi zipangizo zosagwira dzimbiri).
7. Zolepheretsa ndi Zoganizira
Malire a Kupanikizika ndi Kutentha: Sikoyenera kugwiritsa ntchito mphamvu yamphamvu (monga, >PN16) kapena kutentha kwambiri (monga nthunzi yoposa 150).°C).
Zoopsa za Kudzimbiritsa: Zitsulo (monga zitsulo zopangidwa ndi chitsulo) zimatha kudzimbiritsa m'malo ovuta; sinthani kukhala chitsulo chosapanga dzimbiri kapena zinthu zophimbidwa ndi chitsulo chopanda dzimbiri kuti zikhale zovuta.
Zida Zolimba: Zisindikizo zofewa zimatha kutha msanga ndi madzi okhala ndi tinthu tating'onoting'ono; ganizirani ma valve a gulugufe olimba kapena zokutira zina zoteteza.
Kusankha Actuator: Pa ma valve akuluakulu kapena ntchito pafupipafupi, gwiritsani ntchito actuator za pneumatic/hydraulic kuti mupewe kutopa ndi manja.
8. Kukhazikitsa ndi Kusamalira
Kukhazikitsa:
Onetsetsani kuti ma flanges ali olunjika ndipo mabolts amangiriridwa mofanana kuti asatuluke.
Pewani kuyika valavu pansi pa mphamvu ya payipi yochuluka.
Kukonza:
Yang'anani nthawi zonse chisindikizocho ngati chawonongeka kapena chasweka, makamaka ngati chikugwiritsidwa ntchito nthawi zambiri.
Pakani mafuta pa tsinde ndi pa actuator nthawi ndi nthawi kuti muwonetsetse kuti ntchito ikuyenda bwino.
Sinthani chisindikizo ngati patuluka madzi; mapangidwe ena amalola kusintha chisindikizo popanda kuchotsa valavu paipi.
9Malangizo Osankhira Ogulitsa ndi Zogulitsa
Chitsimikizo cha Zinthu: Onetsetsani kuti zisindikizo zikukwaniritsa miyezo yamakampani (monga, FDA ya chakudya, ATEX ya malo ophulika).
Zosankha Zosintha: Ogulitsa ena amapereka mapangidwe oletsa kusinthasintha, zinthu zoteteza moto, kapena zokutira zapadera (monga epoxy, PTFE) za ntchito zapadera.
Mapeto
Ma valve a gulugufe otsekedwa bwino okhala ndi flangendi njira yotsika mtengo komanso yodalirika yowongolera kuthamanga kwa mpweya wochepa mpaka wapakati pazinthu zosafunikira kwenikweni. Kusavuta kwawo, kutseka bwino, komanso kusamalitsa bwino kumapangitsa kuti ikhale chisankho chodziwika bwino m'madzi, HVAC, ndi machitidwe wamba amafakitale. Pamalo ovuta kwambiri, kukweza mapangidwe achilendo kapena zipangizo zapamwamba kumalimbikitsidwa. Nthawi zonse fufuzani mawonekedwe a media, momwe ntchito ikuyendera, ndi zofunikira kuti mutsatire malamulo kuti musankhe valavu yoyenera zosowa zanu.
Mphira uliwonse wokhala ndi malo ozunguliravalavu ya gulugufemonga valavu ya gulugufe wa wafer, valavu ya gulugufe wa lugD7L1X-16Q, Y-strainer, valavu yowunikira wafer,valavu ya chipataZ41X-16Qzofuna, akhoza kulankhulana ndiValavu ya TWSfakitale, tidzakuyankhani nthawi yoyamba.
