Njira Yopangira: Mphamvu Kudzera mu Kupsinjika

Valavu ya mpira wachitsulo yopangidwa ndi chitsulo imapangidwa pogwiritsa ntchito mphamvu yayikulu yokakamiza ku chitsulo cholimba (chipolopolo), chomwe nthawi zambiri chimakhala kutentha kwambiri. Njirayi imawononga chitsulocho ndi pulasitiki, kukonza kapangidwe kake ka tirigu ndikupanga mzere woyenda mosalekeza.

•Mfundo Yofunika Kwambiri:Kusintha kwa pulasitiki pansi pa kupanikizika kumachotsa mipata yamkati ndi ma porosity, zomwe zimapangitsa kuti kapangidwe kake kakhale kolimba komanso kofanana.

• Njira Zachizolowezi:

1. Kutentha kwa Billet

2. Kupangira/Kukanikiza mu mawonekedwe

3. Makina Ovuta

4. Kuchiza Kutentha (kuti kukhale ndi mphamvu komanso kulimba)

5. Makina Opangira Zinthu Mwanzeru (malo ofunikira, ulusi)

6. Kuyang'anira Ubwino

Njira Yopangira Zinthu: Kusinthasintha Kupyolera Mu Kuumba

Avalavu ya mpira wachitsuloAmapangidwa pothira chitsulo chosungunuka m'bowo la nkhungu lomwe linali lopangidwa kale. Chitsulocho chimalimba chikazizira, kutenga mawonekedwe a thupi la valavu, lomwe kenako limatsukidwa ndikupangidwa ndi makina.

• Mfundo Yofunika Kwambiri:Kupanga madzi kumalola kupanga mawonekedwe ovuta kwambiri ndi njira zamkati pang'onopang'ono. Komabe, kumakhala ndi chiopsezo chachikulu cha zolakwika monga kuphatikizika kwa mchenga ndi kufalikira kwa mpweya.

• Njira Zachizolowezi:

1. Kupanga Nkhungu (monga, Nkhungu ya Mchenga, Nkhungu Yogulitsa)

2. Kusungunula Zitsulo

3. Kuthira mu Nkhungu

4. Kuziziritsa ndi Kulimbitsa

5. Kuchotsa ulusi ndi kuyeretsa (kuchotsa zipata)

6. Kupanga Machining

Kugwiritsa Ntchito & Mtengo: Kupanga Chisankho Chotsika Mtengo

Malo anu ogwirira ntchito ndi bajeti yanu ndi zinthu zofunika kwambiri.

Nthawi Yosankha Valavu ya Mpira ya Chitsulo Chopangidwa ndi Forged

• Utumiki Wopanikizika Kwambiri ndi Wofunika Kwambiri:Yabwino kwambiri pa kupsinjika kwa ≥10 MPa m'mafakitale a petrochemical, kupanga magetsi, ndi makina a nthunzi.

• Malo Ovuta Kwambiri:Zabwino kwambiri pa ntchito za cryogenic (LNG), zowononga kwambiri, komanso kugwiritsa ntchito ndi ma pressure shocks kapena water hammer pafupipafupi.

• Zofunikira pa Zombo Zing'onozing'ono:Chosankha chomwe chimakondedwa kwambiri pa ma valves omwe ali pansi pa DN50 (mainchesi awiri) chifukwa cha mphamvu zake zapamwamba m'magawo ang'onoang'ono.

Nthawi Yosankha Valavu ya Mpira wa Chitsulo Chopangidwa ndi Zitsulo

•Cholinga Chachikulu & Machitidwe Okhudza Kupanikizika Pakati:Yabwino kwambiri pa ntchito zamadzi, makina otenthetsera, ndi mafakitale okhala ndi mphamvu ya ≤6.4 MPa.

•Mapangidwe Aakulu ndi Ovuta Kwambiri:Njira yotsika mtengo kwambiri yopangira ma valve DN300 (mainchesi 12) ndi akulu, monga ma valve akuluakulu a chipata kapena agulugufe.

•Mapulojekiti Ofunika Kusamala ndi Mtengo:Kutaya zinthu zochepa komanso kupanga zinthu zambiri kumapangitsa kuti ma valve achitsulo chopangidwa ndi ...

Kusanthula Mtengo

Ma valve achitsulo opangidwa ndi chitsulo nthawi zambiri amakhala okwera mtengo ndi 30%-50% kuposa ena achitsulo chopangidwa ndi chitsulo. Izi zimachitika chifukwa cha mtengo wokwera wa zinthu zopangira (ma billets poyerekeza ndi zitsulo zotsalira), kupanga zinthu zomwe zimafuna mphamvu zambiri, komanso nthawi yayitali yopangira. Kusiyana kwa mtengo kumaonekera makamaka mu ma rating amphamvu kwambiri komanso zinthu zachilendo.

Buku Lanu Losankha Valve la Masitepe Anayi

Tsatirani ndondomeko iyi yopangira zisankho kuti musankhe valavu yoyenera ya mpira wa chitsulo cha kaboni:

1. Yang'anani Kuchuluka kwa Kupanikizika:Kupanikizika Kwambiri (≥10 MPa) → Sankhani Chopangidwa. Kupanikizika Kwapakati-Kotsika (≤6.4 MPa) → Chopangidwa ndi Cast n'choyenera.

2. Unikani Kuopsa kwa Ntchito:Mwankhanza (Yowononga, Yokoka, Yozungulira) → Sankhani Yopangidwa. Yopanda poizoni (Kutentha kwa malo, Kuyenda Kokhazikika) → Yopangidwa ndi yovomerezeka.

3. Dziwani Kukula kwa Valavu:Bowola Lalikulu (≤DN50) → Chopangidwa ndi chopangidwa ndi bwino kwambiri. Bowola Lalikulu (≥DN300) → Chopangidwa ndi chotsika mtengo kwambiri.

Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri)

Q: Kodi mungathe kusiyanitsa valavu ya mpira yopangidwa ndi yopangidwa ndi pulasitala?

Yankho: Kawirikawiri, inde. Ma valve a mpira wachitsulo wopangidwa nthawi zambiri amakhala ndi malo osalala komanso matupi ang'onoang'ono komanso osalala. Ma valve a mpira wachitsulo wopangidwa nthawi zambiri amakhala ndi mawonekedwe okhwima (kuchokera ku nkhungu), kukula kwakukulu, ndi mawonekedwe ovuta kwambiri okhala ndi zizindikiro zodziwika bwino za maziko.

Q: Kodi valavu yopangidwa ndi forged nthawi zonse imakhala yabwino kuposa valavu yopangidwa ndi chitsulo?

A: Sizinali choncho nthawi zonse. "Kuli bwino" kumadalira momwe imagwiritsidwira ntchito. Valavu yachitsulo yopangidwa ndi chitsulo ndi yabwino kwambiri pa ntchito zofunika kwambiri. Komabe, kugwiritsa ntchito valavu yopangidwa ndi chitsulo chokwera mtengo mumzere wamadzi wopanda mphamvu zambiri ndi ndalama zosafunikira. Valavu yachitsulo yopangidwa ndi chitsulo ndiyo yabwino kwambiri.zachumakusankha ntchito zokhazikika.

Q: Kodi ma valve onse a carbon steel ball ndi opangidwa kapena opangidwa ndi chitsulo?

Yankho: Mawu akuti "valavu ya mpira wa chitsulo cha kaboni" amatanthauza zinthuzo, osati njira yopangira. Mavalavu achitsulo cha kaboni amatha kupangidwa pogwiritsa ntchito forging kapena casting, ndichifukwa chake kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri.

Mapeto

Muvalavu ya mpira wachitsulo chopangidwa ndi chitsulo vs valavu ya mpira wachitsuloMkangano, palibe wopambana m'modzi. Valavu yachitsulo yopangidwa ndi chitsulo ndiyo chitsimikizo chosatsutsika cha mphamvu ndi kudalirika pakugwiritsa ntchito mphamvu zambiri komanso zofunika kwambiri. Valavu yachitsulo yopangidwa ndi chitsulo imapereka kusinthasintha kosayerekezeka komanso kugwiritsa ntchito ndalama moyenera pa ntchito zonse, zazikulu, komanso zoganizira bajeti.

Mwa kuwunika mosamala zomwe makina anu amafunikira pa kuthamanga kwa mpweya, zolumikizira, kutentha, ndi kukula kwake poyerekeza ndi mphamvu za mtundu uliwonse wopanga, mutha kusankha motsimikiza valavu yabwino kwambiri yachitsulo cha kaboni yomwe imatsimikizira magwiridwe antchito, chitetezo, ndi mtengo wake.
