Kodi mavavu agulugufe ali oyenerera malo otani?

Mavavu a butterfly, chifukwa cha kapangidwe kawo kosiyanasiyana komanso mawonekedwe osindikiza osinthika, amatha kusinthira kumadera osiyanasiyana atolankhani ndipo atha kugawidwa m'magulu otsatirawa:

1, Universal Media Environment

Madzi ndi njira zamadzimadzi

Oyenera madzi ofotokoza TV monga madzi abwino, zimbudzi, nyanja, mchere, etc. Mwachitsanzo, centerlinevalavu ya butterflyimatha kukwaniritsa zero leak kusindikiza m'madzi abwino, m'madzi am'madzi, m'madzi am'nyanja kuyambira -10 ℃ mpaka 150 ℃, ndipo imagwiritsidwa ntchito m'malo oyeretsera madzi, m'malo operekera madzi am'tauni, ndi makina a ngalande.

Sing'anga ya gasi

Oyenera mpweya monga mpweya, gasi, malasha gasi, nthunzi, etc. Vacuum gulugufe valavu angathe kusamalira mpweya woyera ndi sanali dzimbiri mpweya, ndi kutentha ≤ 300 ℃ ndi kuthamanga 0.1MPa; Pneumatic ventilation butterfly valves amagwiritsidwa ntchito ngati mipweya yafumbi ndi mipweya ya flue, ndipo ndi oyenera kuwongolera zitoliro zamoto ndi uinjiniya wa chilengedwe.

Sing'anga yamafuta

Oyenera mafuta osakanizika, mafuta oyengeka, mafuta opaka mafuta ndi mafuta ena. Mavavu agulugufe osindikizidwa zitsulo (monga ma valve agulugufe atatu) amatha kupirira kutentha kwambiri komanso kuthamanga kwambiri, ndipo amagwiritsidwa ntchito kwambiri pamapaipi onyamula mafuta m'mafakitale a petroleum ndi petrochemical.

2, Special sing'anga chilengedwe

corrosive medium

Acid alkali solution: Mavavu agulugufe okhala ndi fluorine ndi ma valve agulugufe okhala ndi mphira amapangidwa ndi zinthu zosagwira dzimbiri (monga polytetrafluoroethylene ndi mphira), oyenera kugwiritsa ntchito zinthu zowononga kwambiri monga sulfuric acid, hydrochloric acid, ndi sodium hydroxide.

Sing'anga ya mankhwala: Mpando wa vavu wagulugufe wotsekedwa ndi zitsulo zitatu zolimba zomata zowotcherera ndi aloyi wosatentha komanso wosachita dzimbiri, wokhoza kunyamula mpweya wowononga ndi zakumwa monga chlorine ndi hydrogen chloride.

Tinthu ndi inaimitsidwa zolimba TV

The zotanuka kusindikiza dongosolo la centerlinevalavu ya butterflyimatha kutengera semi fluid ndi granular media (monga matope, zamkati, ufa wouma), kupewa kutsekeka kapena kuvala, ndipo imagwiritsidwa ntchito kwambiri m'mafakitale monga migodi, zitsulo, ndi kupanga mapepala.

Kutentha kwakukulu ndi sing'anga yapamwamba

Valavu yagulugufe itatu ya agulugufe imakhala ndi mawonekedwe amitundu itatu, yokhala ndi kukana kutentha kopitilira 600 ℃ ndi kukana kukakamiza kwa PN40 (4.0MPa), koyenera kutentha kwambiri komanso kupanikizika kwambiri monga kutulutsa mphamvu zamagetsi ndi mayunitsi ophwanya petrochemical.

3, Ukhondo ndi chakudya kalasi TV

Mavavu agulugufe amtundu wa chakudya amapangidwa ndi zinthu zopanda poizoni, zopanda fungo, komanso zosavuta kuyeretsa (monga zitsulo zosapanga dzimbiri, UPVC), zomwe zimatsata miyezo ya GMP ndipo ndizoyenera mapaipi oyera m'mafakitale monga chakudya, chakumwa, ndi mankhwala kuti apewe kuipitsidwa kwapakati.
