Udindo wofunikira wa valavu yotseketsa yadzidzidzi ya pneumatic pagawo la gasi wachilengedwe: kuonetsetsa chitetezo ndikulimbikitsa chitukuko cha mafakitale.

Ndi kufunikira kwamphamvu padziko lonse lapansi kwa mphamvu zoyera, gasi wachilengedwe (LNG) wasanduka malo otentha pamsika wamagetsi. Popanga, kusungirako, kuyendetsa ndi kugwiritsa ntchito gasi wachilengedwe, cryogenic pneumatic shut-off valve imagwira ntchito yofunika kwambiri poonetsetsa kuti makina onse a mafakitale akugwira ntchito bwino. Pepalali lisanthula kagwiritsidwe ntchito ka valavu yotsekera mwadzidzidzi ya pneumatic pagawo la gasi wachilengedwe wa liquefied kuchokera kwa akatswiri, ndikukambirana za gawo lake lalikulu pankhaniyi. Choyamba, kugwiritsa ntchito valavu yochepetsera kutentha kwa pneumatic popanga gasi wachilengedwe wa liquefied Popanga LNG, valavu yotsekera mwadzidzidzi imagwiritsidwa ntchito podula kuperekedwa kwa LNG ndi gasi wa feedstock kuonetsetsa chitetezo. za njira yopangira. Mu njira ya liquefaction, valavu yotsika kwambiri ya pneumatic yotseka mwadzidzidzi imatha kuletsa kutuluka kwa gasi wachilengedwe komanso kupewa kuwononga chilengedwe komanso ngozi zachitetezo. Chachiwiri, kugwiritsa ntchito valavu yochepetsera kutentha kwa pneumatic mwadzidzidzi posungira ndi kuyendetsa gasi wachilengedwe wa liquefied Posungira ndi kuyendetsa gasi wachilengedwe, m'pofunika kugwiritsa ntchito valavu yotsekedwa ndi pneumatic mwadzidzidzi kuti iwonetsetse. chitetezo cha matanki osungira a LNG ndi malo oyendera. M'matangi osungira a LNG, ma valve a cryogenic pneumatic shutoff achangu amagwiritsidwa ntchito kuti achepetse kupezeka kwa LNG kuteteza LNG kutayikira. Pogwiritsa ntchito kayendedwe ka LNG, valavu yotsika kwambiri ya pneumatic yotsekera mwadzidzidzi imatha kuteteza bwino kutuluka kwa LNG panthawi yoyendetsa ndikuchepetsa chiopsezo cha ngozi. Chachitatu, kugwiritsa ntchito kwa otsika kutentha kwa pneumatic mwadzidzidzi odulidwa valavu mu ntchito ya liquefied gasi mu ntchito ya liquefied gasi, monga mphamvu mpweya, kupanga mafakitale ndi madera ena, otsika kutentha pneumatic mwadzidzidzi shutdown valavu imaseweranso. udindo wofunikira. Popanga magetsi opangira gasi, valavu yotseketsa yadzidzidzi ya pneumatic imatha kudula gasi wachilengedwe wa liquefied kuti awonetsetse kuti jenereta imagwira ntchito bwino. M'ntchito ya mafakitale, valavu yotsekera yadzidzidzi ya pneumatic imatha kuteteza kutayikira kwa gasi wachilengedwe, kuchepetsa ngozi, komanso kukonza bwino kupanga. Chachinayi, kachitidwe kachitukuko ka valavu yochepetsetsa ya pneumatic yotsika mwadzidzidzi m'munda wa gasi wachilengedwe wokhala ndi liquefied Ndi chitukuko chofulumira chamakampani amafuta achilengedwe, cryogenic pneumatic shut-off valve ipitilizabe kupita patsogolo muukadaulo. Valavu yotsekera yamtsogolo yotsika kwambiri ya pneumatic idzakhala yanzeru kwambiri komanso yodzipangira yokha, kuwongolera chitetezo ndi magwiridwe antchito amakampani a LNG. Kuphatikiza apo, kugwiritsa ntchito zida zatsopano ndi matekinoloje opangira zinthu kudzapititsa patsogolo magwiridwe antchito a ma valve otsekera mwadzidzidzi a pneumatic m'malo otsika kwambiri. Mwachidule, kugwiritsa ntchito ma valve otsika otsika kwambiri a pneumatic shutdown mwadzidzidzi m'munda wa gasi wachilengedwe wa liquefied kumachita gawo lalikulu pakuwonetsetsa kuti ntchito zonse zamakampani zikuyenda bwino. Ndi kupita patsogolo kosalekeza kwa sayansi ndi luso lamakono, ntchito ya valve yochepetsera kutentha kwadzidzidzi ya pneumatic idzapitirizabe kuyenda bwino, ndikupereka chithandizo chodalirika pa chitukuko cha gasi wachilengedwe wa liquefied.
