Ma Valves Oyandama a Mpira Wolimba ndi Wofewa wa GB: Magwiridwe, Ntchito, ndi Miyezo

Ma Valves Oyandama a GB Olimba ndi Ofewa: Magwiridwe, Ntchito, ndi Miyezo

Muyezo wadziko lonse wofewa komanso wosindikizidwa mwamphamvu woyandama woyandama ndi valavu yomwe imagwiritsidwa ntchito kuwongolera ngalande zamadzimadzi, zomwe zimakhala ndi ntchito yabwino yosindikiza komanso kukana kwamadzi pang'ono. M'nkhaniyi, tikuwonetsani mawonekedwe, ntchito, ndi magwiridwe antchito amtundu wamtundu wofewa komanso wosindikizidwa wolimba womata mpira woyandama.

1. Zogulitsa

Mtundu wapadziko lonse lapansi wofewa komanso wosindikizidwa mwamphamvu wa mpira woyandama uli ndi izi:

-Kukana kwamadzimadzi otsika: Ma valve a mpira amakhala ndi kukana kwamadzi otsika kwambiri pakati pa mitundu yonse ya valavu, ngakhale kuchepetsedwa kwa ma valve a mpira, kukana kwawo kwamadzi kumakhala kochepa.

-Kutsegula ndi kutseka kofulumira komanso kosavuta: Malingana ngati tsinde la valve likuzungulira 90 °, valavu ya mpira idzamaliza kutsegulira kwathunthu kapena kutseka kwathunthu, kuti zikhale zosavuta kukwaniritsa kutsegula ndi kutseka mwamsanga.

-Kusindikiza kwabwino: Mpando wa valve wa mpira watsekedwa, ndikusindikiza bwino.

2. Kugwiritsa Ntchito Mankhwala

The dziko muyezo zofewa ndi zolimba losindikizidwa mpira valavu akuyandama ndi oyenera mafuta, gasi, mankhwala, mankhwala, chakudya, magetsi, madzi, zitsulo, ndi zomangamanga mafakitale. Valavu ya mpira yoyandama ya Flange ndi njira yolumikizira wamba, yoyenera pamikhalidwe yosiyanasiyana yogwirira ntchito.

3. Main ntchito specifications

Kuthamanga mwadzina (MPa): Kuthamanga kwadzidzidzi kwa valve ya mpira woyandama wofewa komanso wolimba wosindikizidwa ndi 0.6 ~ 42.0 MPa, ndipo milingo yoyenera yokakamiza imatha kusankhidwa malinga ndi momwe ntchito zikuyendera.

Kutentha koyenera: Kutentha koyenera kwa mavavu oyandama amtundu wofewa komanso osindikizidwa mwamphamvu ndi -196 ℃ ~ 550 ℃, pomwe mavavu amtundu wofewa komanso osindikizidwa olimba ndi oyenera gasi, mafuta amafuta ndi media ena okhala ndi H2S. ndi CO2.

Makanema ogwiritsiridwa ntchito: Ma valve a mpira ofewa komanso omata oyandama adziko lonse ndi oyenera kuwulutsa nkhani monga madzi, nthunzi, mafuta, gasi wamadzimadzi, ndi gasi.

4. Main chigawo zipangizo

chigawo chachikulu zipangizo dziko muyezo zofewa ndi zovuta losindikizidwa valavu akuyandama mpira monga mpweya zitsulo mndandanda, zosapanga dzimbiri mndandanda zosapanga dzimbiri, mndandanda sulfure kugonjetsedwa, ndi otsika kutentha mndandanda zitsulo. Zidazi zimatha kukwaniritsa zofunikira zamitundu yosiyanasiyana yogwirira ntchito, kuwonetsetsa kukhazikika komanso kudalirika kwa valve.

5. Miyezo ya kuphedwa

Valavu ya mpira yoyandama yofewa komanso yolimba yosindikizidwa idapangidwa ndikupangidwa motsatira mfundo monga GB/T12237, GB/T12221, GB/T12224, ndi GB/T12220. Miyezo iyi imatchula zofunikira za kutalika kwa mapangidwe, kulumikiza ma flanges, kuyesa ndi kuyang'ana ma valve, kuonetsetsa kuti mankhwala odalirika ali abwino.

Mwachidule, valavu yamtundu wofewa komanso yolimba yosindikizidwa ndi valve yochita bwino kwambiri, yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Kumvetsetsa mawonekedwe ake, kagwiritsidwe ntchito, ndi magwiridwe antchito akulu kungatithandize kusankha bwino ndikugwiritsa ntchito valavu yamtunduwu.
