Dzulo, gulu lamavavu a mpira olumikizidwakuchokera ku Jinbin Valve idapakidwa ndi kutumizidwa.

Valavu yolumikizira mpira yonse ndi mtundu wa valavu ya mpira yokhala ndi kapangidwe ka thupi la valavu ya mpira yonse. Imafika poyimitsa cholumikiziracho pozungulira mpirawo 90° mozungulira mzere wa tsinde la valavu. Mbali yake yayikulu ndi yakuti zigawo zonse za thupi la valavu zimalumikizidwa zonse kudzera muukadaulo wolumikizira, popanda zolumikizira zotayika monga ma flanges kapena ulusi. Kutseka kwake ntchito komanso mphamvu zake ndizabwino kwambiri kuposa za mitundu yachikhalidwe yolumikizira mavalavu a mpira. Ndi yoyenera mayendedwe azinthu monga madzi, gasi, mafuta ndi madzi osiyanasiyana owononga.

Ubwino wa welded kwathunthumpira vavu Makampaniimaonekera makamaka m'mbali zitatu:

1. Ili ndi magwiridwe antchito amphamvu kwambiri osindikiza.

Chifukwa chosakhala ndi malo otsekera olumikizidwa ndi flange, imapewa zoopsa zotuluka zomwe zimayambitsidwa ndi mabolt omasuka ndi zida zotsekera zakale m'ma valve achikhalidwe otsekera, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pazofunikira zachitetezo ponyamula zinthu zoyaka moto, zophulika, zapoizoni kapena zopanikizika kwambiri.

2. Kapangidwe kake ndi kolimba komanso kodalirika.

Kapangidwe konse ka chitsulo cholumikizidwa kali ndi mphamvu yolimbana ndi kugwedezeka komanso kugwedezeka, ndipo kamatha kusintha kuti kagwirizane ndi kupanikizika kwakukulu (mpaka 10MPa ndi kupitirira apo), kutentha kwambiri (-29℃ mpaka 300℃), pansi pa nthaka ndi chinyezi komanso malo ena ovuta. Kukhazikika kwake kuli bwino kwambiri kuposa matupi a ma valve ogawanika.

Chachitatu, mtengo wokonza ndi wotsika. Kapangidwe kake kolumikizidwa kamachepetsa ziwalo zosalimba ndipo sikafuna kumangidwa pafupipafupi kwa maboluti. Nthawi yogwira ntchito yake imatha kufika zaka makumi angapo, zomwe zimachepetsa kwambiri kuchuluka kwa ndalama zokonzera komanso nthawi yopuma. Nthawi yomweyo, kapangidwe kake kakang'ono kamathanso kusunga malo oyika.

Zochitika zodziwika bwino za mavavu a mpira olumikizidwa mokwanira zimakhala m'minda yokhala ndi zofunikira kwambiri pakusindikiza magwiridwe antchito, chitetezo komanso kukhazikika kwa nthawi yayitali (Kugwiritsa Ntchito Valuvu ya Mpira):

Mu mapaipi amafuta ndi gasi akutali, ndi gawo lofunika kwambiri lowongolera malo oikira pansi pa nthaka, lotha kupirira dzimbiri la nthaka ndi kusintha kwa nthaka, ndikuwonetsetsa kuti mafuta ndi gasi akuyenda mtunda wautali ndi otetezeka.

Mu maukonde otenthetsera mpweya m'mizinda ndi pakati, kukana kwake kuthamanga kwambiri komanso kutayikira pang'ono kumatha kuchepetsa bwino kutayika kwa mphamvu komanso zoopsa zachitetezo.

Mu njira yoyendetsera mafakitale a petrochemical ndi mankhwala, ndi yoyenera kunyamula zinthu zowononga, zoyaka moto komanso zophulika, zomwe zimakwaniritsa zofunikira pa ntchito yovuta.

Kuphatikiza apo, imagwiritsidwanso ntchito kwambiri m'mapaipi otumizira madzi amphamvu kwambiri a mapulojekiti osungira madzi ndi machitidwe apadera oyendera madzi m'munda watsopano wamagetsi chifukwa cha kudalirika kwake kwakukulu.

Ma valve a mpira olumikizidwa bwino, omwe ali ndi kuthekera koti "asatuluke" komanso kulimba, akhala zida zomwe amakonda kwambiri pamavuto olamulira madzi omwe ali ndi mphamvu zambiri komanso omwe ali pachiwopsezo chachikulu. Ma valve a Jinbin akhala akatswiri pakupanga ma valve kwa zaka 20. Ngati muli ndi zosowa zina zokhudzana ndi izi, chonde titumizireni uthenga pansipa ndipo mudzalandira yankho mkati mwa maola 24!
