ISO 15848 Fugitive Emission Globe Valve

Muyezo wa ISO 15848 ndi muyeso wapadziko lonse lapansi pakuyezera, kuyesa, ndikuzindikiritsa njira zotulutsira mpweya wotuluka m'mavavu akumafakitale, monga ma volatile organic compounds (VOCs) ndi kutayikira kwazinthu zowopsa. Cholinga chake ndikuwongolera chiwopsezo cha kuipitsidwa kwa chilengedwe cha mavavu akumafakitale poyesa njira zoyesera ndi kachitidwe kamagulu. Muyezo uwu wagawidwa m'magawo angapo, Gawo 1 (ISO 15848-1) lomwe likuyang'ana kwambiri kachitidwe kamagulu ndi njira zoyeserera zoyezetsa mtundu wa ma valve, ndi Gawo 2 (ISO 15848-2) lofotokoza zofunikira pakuyesa kuvomereza kuvomereza.

Tsopano tiyeni tiwone imodzi mwa dongosolo lathu la JUDU kuti 3 '', CL10000，API 6A ma valve a globe, Wogwiritsa Ntchito Mapeto a Chemical project akuyenera kuyesa kuti akwaniritse 50ppm maximum level emission class class C01 molingana ndi ISO15848-1 ndi ISO15848-2

Tsatanetsatane wa vavu: monga pa tebulo 1

Kujambula kwa vavu

Zithunzi za Vavu:

Monga momwe makasitomala amafunira, ma PC 10 awa ma valve a globe, 9pcs ikuyenera kutulutsa mpweya wothawathawa malinga ndi ISO 15848-2, ndipo 1pc iyenera kutulutsa mpweya wothawa kwawo malinga ndi ISO 15848-1.

ISO 15848-1: Kuyesa kwamtundu

● Kukonzekera:
Mavavu ayenera kutsimikizira mtundu wa ISO 15848-1 kuti awonetsetse kuti amayesedwa pansi pa kutentha kwanthawi yayitali komanso kupanikizika, ndikuwonetsetsa kuti zonyamulazo zauma.

● Njira yoyesera:
Pogwiritsa ntchito njira yakununkhiza (onani Zowonjezera B za ISO 15848-1), mpweya wa helium umagwiritsidwa ntchito ngati sing'anga yoyesera (kuyera ≥ 97%) kuyeza kuchuluka kwa kutayikira (gawo: ppmv, 1ppmv=1ml/m³)

● Kuyesa:
Vavu yapadziko lonse lapansi iyenera kumaliza mayeso otsekedwa - otseguka kwathunthu - otsekedwa kwathunthu. Tsimikizirani kukhazikika kwa ntchito yosindikiza

● Zotsatira Zoyesa ndi TUV:
Woyang'anira TUV.R adawonapo kutulutsa kothawa kwa 1pcs globe vales molingana ndi ISO15848- 1:2017. Nambala yosankhira yosankha valve inali JUDU20050309, tsatanetsatane wawona pansipa:

● Zithunzi Zoyesa:

ISO 15848-2 Kuyesa Kuvomereza Kupanga

● Kukonzekera:
Zimangogwira ntchito pamapangidwe a ma valve omwe adutsa mayeso amtundu wa ISO 15848-1, kuwonetsetsa kuti valavu yonyamula yowuma isanayesedwe, kupewa chinyezi chomwe chimakhudza zotsatira za mayeso, kulimbitsa chisindikizo cha valve, ndikuwonetsetsa kuti kusindikiza koyambirira kumakwaniritsa zofunikira.

● Njira yoyesera:
Kuthamanga koyezetsa kosasintha ndi 6 bar ndipo kutentha ndi kutentha kwa chipinda. Pogwiritsa ntchito njira yofunkhira (onani Zowonjezera B za ISO 15848-1), mpweya wa helium umagwiritsidwa ntchito ngati njira yoyesera (kuyera ≥ 97%) kuyeza kuchuluka kwa kutayikira (gawo: ppmv, 1ppmv = 1ml / m ³)

● Kuyesa:
Kutayikira kwa chisindikizo cha valve: Yezerani kutayikira koyambirira valavu ikakanikizidwa pamalo otseguka, ndikuyesanso pambuyo pamizere 5 yotseguka komanso yotseka kuti muwonetsetse kuti ntchito yosindikiza ikhazikika.
Kutayikira kwa chisindikizo cha vavu: Kupanikizika kukakhazikika, zindikirani kutayikira pa chisindikizo chokhazikika, ndipo pamafunika kukhala otsika kuposa malire a ppmv omwe atchulidwa muyeso.

● Zotsatira Zoyesa ndi TUV:
Woyang'anira TUV.R adawona kutulutsa kothawa kwa 9pcs ma valve a globe molingana ndi ISO15848- 2:2017, ndipo zotsatira zinakwaniritsa zofunikira, Tsatanetsatane onani pansipa:

● Zithunzi Zoyesa:

Sankhani Malingaliro

● Kusankha patsogolo kwa ISO 15848-1
Mavavu amayenera kugwiritsidwa ntchito popanga zinthu zowopsa kwambiri monga zamadzimadzi oopsa kwambiri, oyaka, komanso ophulika;
Ayenera kukwaniritsa zofunikira za satifiketi yapadziko lonse lapansi (monga EU CE, TÜ V certification);
Panthawi yopangira, ndikofunikira kutsimikizira kulimba kwa nthawi yayitali (monga makina a 610 ofunikira ndi API 624)

● Kusankha patsogolo kwa ISO 15848-2
Kuvomera mwachangu kumafunikira panthawi yopanga zochuluka (monga zitsanzo zosachepera 1 unit pa batch);
Valavu yadutsa chiphaso cha ISO 15848-1 ndipo imangofunika kutsimikizira kugwirizana kwa kuchuluka kwa kutayikira;
Zinthu zotsika mtengo komanso zotsika kwambiri (monga madzi wamba am'mafakitale).
