Mavavu (chigawo chowongolera mumayendedwe a mapaipi)
Tsatanetsatane wa Zamalonda:
Monga gawo lofunikira pakuwongolera mapaipi, ntchito zazikulu za mavavu zimaphatikizapo kutsegula ndi kutseka, kuwongolera, kupatutsa, kupewa kubweza, komanso kutetezedwa kwapakatikati. Chifukwa chapadera pamakampani amafuta, ma valve amayenera kugwira ntchito mokhazikika kwa nthawi yayitali pansi pazovuta monga kuthamanga kwambiri, kutentha kwambiri, dzimbiri lamphamvu, ndi zonyansa. Kuchita kwawo kumakhudza mwachindunji chitetezo chopanga, mphamvu zamagetsi, komanso kuteteza chilengedwe.
M'makampani a petroleum, malo ogwirira ntchito a ma valve ndi ovuta kwambiri, omwe amaika zofunikira kwambiri pa kukana kutentha ndi mphamvu zamapangidwe a ma valve. Kusankhidwa kwa ma valve kuyenera kuganizira mozama za sing'anga (monga viscosity, corrosiveness, solid particle content), kuthamanga kwa ntchito, kutentha kwapakati, njira yolumikizira, ndi zofunikira zodzilamulira. Mitundu yodziwika bwino ya ma valve imaphatikizapo ma valve a zipata, ma valve a mpira, ma valve a globe, ma valve owunika, ma valve a butterfly, ndi ma valve otetezera, iliyonse ili ndi mawonekedwe ake apadera komanso zochitika zomwe zimagwira ntchito. Ndikukula kwa mafakitale a petroleum kupita kumadera akuya, polar, komanso malo osagwirizana ndi mafuta ndi gasi (monga gasi wa shale ndi mchenga wamafuta),
Tekinoloje ya ma valve ikupanga zatsopano ndipo ntchito zake zikuchulukirachulukira. M'tsogolomu, ma valve adzakhala otetezeka kwambiri, moyo wautali, ndi nzeru zambiri kuti akwaniritse zofuna za makampani opanga mphamvu padziko lonse lapansi kuti zikhale zogwira mtima, zosamalira zachilengedwe, komanso zodalirika zoyendetsera madzimadzi.
Ntchito:
njira. Ma valve opangira pobowola amagwiritsidwa ntchito makamaka m'zigawo zazikulu monga zida zamutu, makina oyendetsa matope, gulu loletsa kuphulika, ndi mapaipi opha zitsime. Mavavuwa amapangidwa ndi zida zapadera za aloyi zomwe zimalimbana ndi sulfure ndipo zimatha kupirira zipsyinjo zogwira ntchito za kutentha kwambiri komanso kuthamanga kwambiri, komanso media acidic yomwe ili ndi hydrogen sulfide. Pakati pawo, valavu ya throttle ndiyofunikira kwambiri pakuwongolera kuthamanga kwa mutu, ndipo kapangidwe kake kamene kamapangidwira mwapadera kamatha kukwaniritsa malamulo oyendetsera bwino, kuteteza kuchitika kwa ngozi zophulika. Ndi chitukuko cha zitsime zakuya kwambiri ndi chitukuko cha gasi wa shale, ma valve akupita kumalo othamanga kwambiri, kukana kwa dzimbiri kwamphamvu, ndi njira yanzeru kwambiri, zomwe zimapereka chitsimikizo chodalirika cha chitetezo pakubowola.
Valavu ya Grandtech ili ndi tsogolo ndi machitidwe awa:
Mawonekedwe:
· Kutentha kwakukulu komanso kukana kuthamanga kwambiri, kukana kwa dzimbiri
· Kuchita bwino komanso kusindikiza kwabwino
· Sinthani kumadera osiyanasiyana ogwira ntchito komanso zofunikira zapadera zantchito
