Kodi A Triple Offset Butterfly Valve: Vs. Mtundu wa Concentric

Kodi Valve ya Gulugufe Katatu ndi chiyani: kusiyana pakati pa mavavu agulugufe okhazikika komanso ochita bwino kwambiri?

M'munda wa ma valve a mafakitale, ma valve a butterfly amagwiritsidwa ntchito kwambiri poyendetsa madzimadzi chifukwa cha mawonekedwe awo osakanikirana komanso kutsegula ndi kutseka mofulumira. Ndi chitukuko chaukadaulo, mapangidwe a mavavu agulugufe akhala akukonzedwa mosalekeza, zomwe zimapangitsa kuti pakhale mitundu ingapo mongavalavu ya butterfly yapakati, valavu yagulugufe yawiri eccentricndiatatu eccentric butterfly valve. Nkhaniyi iyamba kuchokera pamakonzedwe, kufananitsa magwiridwe antchito ndi malingaliro osankhidwa, kusanthula mozama zabwino zazikulu zaatatu eccentric butterfly valve, ndi kufufuza momwe mungasankhire zapamwambaopanga ma valve a butterflyndiogulitsa.

Kagawidwe ndi Kapangidwe ka Mavavu a Gulugufe

 1. Vavu ya Gulugufe Wapakati

 - Zomangamanga: Chovala cha valve ndi coaxial ndi tsinde la valve, malo osindikizira amapangidwa mofanana, ndipo mpando wa valve nthawi zambiri umapangidwa ndi zinthu zofewa (monga mphira).

- Ubwino wake: Mtengo wotsika, kapangidwe kosavuta, koyenera kupanikizika kochepa komanso kutentha kwabwino.

- Zoipa: Kukana kwakukulu kwa mikangano, ndipo ntchito yosindikiza imachepa ndi kuwonjezeka kwa kutentha ndi kupanikizika.

- Zochitika zantchito: malo osagwira ntchito movutikira monga chithandizo chamadzi, HVAC, ndi zina.

2. Vavu ya Gulugufe Wawiri Eccentric

- Zomangamanga:

- Choyamba eccentricity: tsinde la valve limapatuka pakati pa mbale ya valve kuti muchepetse kukangana kwa kutsegula ndi kutseka.

- Chachiwiri eccentricity: Malo osindikizira a valve amapatuka pakatikati pa payipi kuti akwaniritse kusindikiza kopanda kulumikizana.

- Ubwino wake: torque yaying'ono yotsegula ndi kutseka, ntchito yabwino yosindikiza kuposa valavu ya butterfly yapakati.

- Zoipa: zinthu zosindikizira zimakonda kukalamba pansi pa kutentha kwakukulu komanso kuthamanga kwambiri.

- Zochitika zantchito: mapaipi apakatikati ndi otsika pamafakitale amafuta ndi mankhwala.

3. Valve ya Gulugufe Watatu wa Eccentric

- Zomangamanga:

- Choyamba eccentricity: tsinde la valve limapatuka pakatikati pa mbale ya valve.

- Chachiwiri eccentricity: Malo osindikizira a valve amapatuka pamzere wapakati wa payipi.

- Chachitatu eccentricity: Kusindikiza pamwamba pa ngodya ya cone kumakwaniritsa kusindikiza kwachitsulo molimba.

- Ubwino wake:

- Kukangana kwa ziro kutsegula ndi kutseka: Chipinda cha valve ndi mpando wa valve zimalumikizana pokhapokha zitatsekedwa, zomwe zimatalikitsa moyo wautumiki.

- Kutentha kwakukulu ndi kukana kupanikizika: Zisindikizo zachitsulo zimatha kupirira kutentha kwambiri kuposa 400 ℃ ndi Class 600 pressure level.

- Kusindikiza kwapawiri: Yoyenera kugwirira ntchito movutikira komwe sing'anga imayenda mbali zonse ziwiri.

- Zochitika zantchito: Makina ofunikira okhala ndi kutentha kwakukulu komanso kuthamanga kwambiri monga mphamvu, petrochemical, ndi LNG.

4. High Performance Butterfly Valve

- Tanthauzo: Kawirikawiri amatanthauza valavu ya butterfly yokhala ndi mawonekedwe awiri kapena atatu, omwe ali ndi zizindikiro za torque yochepa, kusindikiza kwakukulu komanso moyo wautali.

- Ubwino waukulu: Ikhoza kusintha mavavu ena a pakhomo ndi mavavu a mpira ndi kuchepetsa mtengo wa machitidwe a mapaipi.

Chifukwa chiyani valavu yagulugufe katatu ndiye chisankho choyamba chamakampani

 1. Kusanthula ubwino wamapangidwe

- Metal hard seal design: Wopangidwa ndi chitsulo chosapanga dzimbiri, chitsulo cha alloy ndi zinthu zina, sichichita dzimbiri komanso chosavala.

- Conical kusindikiza pamwamba: kukhudzana kwapang'onopang'ono kumapangidwa potseka, ndipo chisindikizo chimakhala cholimba.

- Kukonzekera kwachitetezo chamoto: mitundu ina imakumana ndi API 607 ​​​​yotetezedwa ndi moto ndipo ndiyoyenera malo owopsa.

2. Kufananiza ndi valavu yagulugufe yawiri eccentric

3. Milandu yogwiritsira ntchito mafakitale

- Makampani opanga magetsi: amagwiritsidwa ntchito m'makina opangira madzi a boiler, osamva kutentha kwa nthunzi.

- Petrochemical: Yang'anirani zofalitsa zowononga m'magawo osweka.

- Kusungirako ndi mayendedwe a LNG: Pitirizani kusindikiza kudalirika pansi pa kutentha kwambiri.

Momwe mungasankhire opanga ma valve agulugufe apamwamba komanso ogulitsa 

1. Yang'anani mphamvu zamakono

- Patents ndi certification: Muziika patsogoloopangaomwe ali ndi tekinoloje yama valve agulugufe wapatatu ndipo amavomerezedwa ndi API 609 ndi ISO 15848.

- Kuthekera kosintha mwamakonda: Kodi mungapereke ma valve okhala ndi makulidwe osagwirizana ndi zipangizo zapadera (monga Monel, Inconel).

2. Yang'anani pa kayendetsedwe ka khalidwe la kupanga

- Kuyesa kwazinthu: Malipoti azinthu (monga miyezo ya ASTM) ndiyofunikira.

- Kuyesa magwiridwe antchito: Kuphatikizira mayeso osindikizira ndi mayeso ozungulira moyo (monga kutsegulira 10,000 ndi kutseka popanda kutayikira).

3. Onani mtengo ndi kuthekera kopereka

- Ubwino wa mafakitale aku China:

- Kupikisana kwamitengo: Chinaothandizira agulugufekudalira kupanga kwakukulu, ndipo mtengo wake ndi 30% -50% wotsika kuposa wamitundu yaku Europe ndi America.

- Kutumiza mwachangu: Kuwerengera kokwanira kwazinthu zokhazikika, zothandizira masabata a 2-4 operekera.

4. Yang'anani pambuyo-kugulitsa ntchito

- Perekani chitsogozo chokhazikitsa pamalowo, kukonza nthawi zonse komanso magawo osinthira.

Zochitika zamtsogolo za mavavu agulugufe atatu-eccentric

1. Kukwezera mwanzeru: Masensa ophatikizika ndi ma module a IoT kuti aziwunika momwe ma valve alili munthawi yeniyeni.

2. Kugwiritsira ntchito zinthu zachilengedwe: Adopt kapangidwe kopanda kutayikira komanso mpweya wocheperako (ISO 15848 certification).

3. Kukula kwa gawo la kutentha kwambiri: Imagwira ntchito kwambiri ngati hydrogen yamadzimadzi (-253 ℃) ndi helium yamadzimadzi.

Mapeto 

Valavu yagulugufe ya katatuyakhala valavu yokondedwa yamapaipi apamwamba kwambiri komanso opanikizika kwambiri m'mafakitale okhala ndi mawonekedwe ake osinthira zitsulo zolimba komanso moyo wautali wautumiki. Kaya kufanizitsa zabwino za magwiridwe antchito ndivalavu yagulugufe yawiri eccentrickapena kusiyanitsa zochitika zogwiritsira ntchitovalavu ya butterfly yapakati, ndikofunikira kusankha awopanga valavu butterflyndi luso lodalirika ndi mtengo wololera.Mafakitale a butterfly valveku China akukhala maziko oyambira ogula padziko lonse lapansi ndiukadaulo wawo wokhwima komanso mtengo wake. Ngati mukufuna kudziwa zambirivalavu yagulugufe yogwira ntchito kwambirimagawo aukadaulo kapena pezani mawu, chonde titumizireni - katswiri wopereka yankho la valve!
