Dzulo, gulu lavalavu mpira wowotchererakuchokera ku Jinbin Valve idapakidwa ndikutumizidwa.

Valavu yowotcherera mokwanira ndi mtundu wa valavu ya mpira yokhala ndi mawonekedwe ophatikizika a ma valve a mpira. Imakwaniritsa kuyimitsa kwa sing'angayo pozungulira mpira 90 ° kuzungulira tsinde la valve. Cholinga chake chachikulu ndi chakuti zigawo zonse za thupi la valve zimagwirizanitsidwa palimodzi kudzera mu teknoloji yowotcherera, popanda zomangira zowonongeka monga flanges kapena ulusi. Magwiridwe ake osindikiza komanso mphamvu zamapangidwe ndizabwinoko kuposa momwe zimalumikizirana ndi ma valve a mpira. Ndi oyenera mayendedwe atolankhani monga madzi, gasi, mafuta ndi zosiyanasiyana dzimadzimadzi dzimbiri.

Ubwino mokwanira weldedMpira valavu Makampanizimawonekera makamaka m'mbali zitatu:

1. Ili ndi ntchito yosindikiza yamphamvu kwambiri.

Chifukwa cha kusakhalapo kwa malo osindikizira opangidwa ndi flange, amapewa kuopsa kwa ma bolts otayirira komanso zida zomata zokalamba m'mavavu ampira ampira, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pachitetezo ponyamula zinthu zoyaka, zophulika, zapoizoni kapena zopanikizika kwambiri.

2. Mapangidwe ake ndi olimba komanso odalirika.

Kapangidwe kawonse ka welded kamakhala ndi kukana kwambiri komanso kukana kugwedezeka, ndipo kumatha kutengera kuthamanga kwambiri (mpaka 10MPa ndi kupitilira apo), kutentha kwakukulu (-29 ℃ mpaka 300 ℃), mobisa ndi chinyezi komanso malo ena ovuta. Kukhazikika kwake ndikwapamwamba kwambiri kuposa matupi a valve ogawanika.

Chachitatu, mtengo wokonza ndi wotsika. Kapangidwe ka welded kumachepetsa magawo omwe ali pachiwopsezo ndipo sikufuna kumangirira pafupipafupi ma bolts. Moyo wake wautumiki ukhoza kufika zaka makumi angapo, kutsika kwambiri kufupikitsa kwa nthawi yokonza ndi kutsika mtengo. Panthawi imodzimodziyo, mapangidwe a compact amathanso kusunga malo osungira.

Zochitika zodziwika bwino za mavavu a mpira wowotcherera mokwanira zimakhazikika m'magawo omwe ali ndi zofunika kwambiri pakusindikiza, chitetezo ndi kukhazikika kwanthawi yayitali (Kugwiritsa Ntchito Vavu ya Mpira):

M'mapaipi akutali amafuta ndi gasi, ndi gawo lowongolera pakuyalidwa mobisa, lomwe limatha kupirira dzimbiri komanso kusintha kwachilengedwe, kuonetsetsa chitetezo chamayendedwe akutali amafuta ndi gasi.

M'magasi akumatauni komanso ma netiweki otenthetsera apakati, kukana kwake kwamphamvu komanso kutsika kochepa kumatha kuchepetsa kutayika kwamphamvu komanso kuwopsa kwachitetezo.

M'mapaipi a mafakitale a petrochemical ndi mankhwala, ndi oyenera kunyamula zinthu zowononga, zoyaka komanso zophulika, kukwaniritsa zofunikira pakugwira ntchito movutikira.

Kuphatikiza apo, imagwiritsidwanso ntchito kwambiri pamapaipi opatsira madzi othamanga kwambiri pamapulojekiti osungira madzi ndi machitidwe apadera oyendetsa madzimadzi m'munda watsopano wamagetsi chifukwa chodalirika kwambiri.

Ma valve opangidwa bwino ndi mpira, omwe ali ndi kuthekera komanso kukhazikika kwa "zero" ndi kulimba, akhala zida zomwe amakonda kwambiri pakuwongolera kuthamanga kwambiri komanso kuopsa kwamadzimadzi. Mavavu a Jinbin adakhazikika pakupanga ma valve kwa zaka 20. Ngati muli ndi zosowa zina, chonde titumizireni pansipa ndipo mudzalandira yankho pasanathe maola 24! (One Piece Ball Valve)
