Posachedwapa, malo ochitira masewera olimbitsa thupi a Jinbin valve amaliza ntchito yolimbitsa thupi kwambirivalavu ya magalasiNtchito yopangira, zofunikira zake ndi DN100, DN200, mphamvu yogwirira ntchito ndi PN15 ndi PN25, zinthuzo ndi Q235B, kugwiritsa ntchito silicone rabara seal, chogwirira ntchito ndi flue gas, blast furnace gas. Akatswiri a workshop atayang'anitsitsa, ma valve a magolovesi amphamvu awa apakidwa ndipo ali okonzeka kutumizidwa ku Russia.

Kotero, kodi makhalidwe ndi ubwino wa valavu yotchingira mbale yothamanga kwambiri ndi ziti?

Mphamvu yothamanga kwambiri

Kapangidwe ka mphamvu ya PN16 (1.6MPa) ndi PN25 (2.5MPa) kakhoza kusinthidwa kuti kagwirizane ndi njira ya mapaipi opanikizika kwambiri. M'mimba mwake mwa DN100 ndi DN200 mutha kukwaniritsa zofunikira zosiyanasiyana za kudula kwa njira yolumikizirana, kaya ndi njira yaying'ono komanso yapakatikati yoyendetsera kayendedwe ka madzi kapena njira yayikulu yolumikizirana mapaipi, ikhoza kukhala yokhazikika.

2. Kugwira ntchito kodalirika kosindikiza

Kapangidwe kotseka kolondola, kokhala ndi zipangizo zotsekera zapamwamba kwambiri, ngakhale pansi pa mikhalidwe yopanikizika kwambiri, kumatha kuletsa kutuluka kwa cholumikiziracho, kuonetsetsa kuti dongosolo la mapaipi ndi lolimba, komanso kuonetsetsa kuti ntchitoyo ndi yotetezeka.

3. Kugwira ntchito bwino kwambiri kwa zinthu

Thupi lalikulu limapangidwa ndi chitsulo cha Q235B chomwe chili ndi mphamvu zabwino, kulimba komanso mphamvu zogwirira ntchito, kupirira kokhazikika, kukana mwamphamvu kugunda, ndipo chimatha kusintha momwe zinthu zilili zovuta kugwira ntchito ndikuwonjezera moyo wautumiki wa chipangizocho.valavu yooneka ngati akhungu.

4. Ntchito yabwino komanso kukonza

Yokhala ndi chipangizo choyendetsera ndi manja, ntchito yosinthira ndi yosavuta komanso yosinthasintha, mitundu ina imathandizira kuwongolera kutali; Kapangidwe kakang'ono, malo ochepa, kuyika ndi kusokoneza kosavuta, komanso mtengo wotsika wokonza.

Momwe mungagwiritsire ntchito ng'anjo ya valve yophulika ya golidi yothamanga kwambiri

1. Malo opangira mafuta: Mu mapaipi opanikizika kwambiri monga mayendedwe a mafuta osakonzedwa ndi kukonza zinthu zopangira mankhwala, amagwiritsidwa ntchito pochotsa zinthu zofalitsa panthawi yokonza zida ndi kugawa mapaipi kuti ateteze kutuluka kwa zinthu zoyaka ndi zophulika ndikuwonetsetsa kuti ntchitoyo ndi yotetezeka.

2. Makampani opanga magetsi: Ndi oyenera makina amphamvu monga mapaipi a nthunzi m'malo opangira magetsi otentha ndi mapaipi amadzi ozungulira m'malo opangira magetsi a nyukiliya kuti achepetse kufalikira kwapakati komanso kulekanitsa zida ndikuwonetsetsa kuti makinawo ndi olimba panthawi yokonza kapena kugwiritsa ntchito zida zamagetsi.

3. Makampani opanga zitsulo: Mu ng'anjo yophulika, mapaipi a okosijeni/nayitrogeni ndi zina, kuti athe kuthana ndi kutentha kwambiri komanso kupanikizika kwambiri, kutseka mapaipi ndi kutsekeka kwa media, kuti akwaniritse zosowa zokhwima zowongolera chitetezo popanga zitsulo.

4. Dongosolo lotumizira mpweya: limagwiritsidwa ntchito poyang'anira mapaipi a mpweya okhala ndi mphamvu zambiri mumzinda. Pa nthawi yokonza, valavu yobisika imagwiritsidwa ntchito kuletsa mpweya kutuluka, kupewa kutuluka kwa mpweya, ndikuwonetsetsa kuti ntchito yomanga ndi yotetezeka komanso yodalirika ya mpweya woperekedwa mumzinda.

Ndi makhalidwe a kupanikizika kwamphamvu, kutseka kwakukulu komanso kukonza kosavuta, valavu yotchinga yamtunduwu yakhala chida chachikulu chodulira pakati komanso kudzipatula kwachitetezo m'mapaipi opanikizika kwambiri a mafakitale.
