Kev siab siab2- txoj kevPob Li Qub Piav Qhia
High-siab ob-txoj kev pob pob valve yog tsim tshwj xeeb rau kev tswj hwm siab. Nws tau txais ib ob-daim valve lub cev (lub valve valve lub cev + ib lub cev muaj valve lub cev) thiab cov qauv sib txuas txuas. Qhov nruab nrab tau qhib thiab kaw lossis ntws ntws los tswj los ntawm kev tig lub pob 9 {{9 {} degree. Nws yog qhov haum rau chav kawm 150 ~ 2500lb (PD1.0) PN420) High-siab Scenarios.
Tus qauv tseem ceeb suav nrog:
Split valve lub cev: lub ntsiab thiab ib lub cev tso pa hluav taws xob txuas nrog los ntawm bolts lossis flanges, uas yooj yim rau kev sib pauv thiab kev hloov pauv;
Floating / Taag Pob Tsim:
Ntab pob: qhov nruab nrab lub siab thawb lub pob kom nias lub nplhaib sib khi, uas yog tsim nyog rau nruab nrab thiab qis dua lossis sib npaug zos rau PN25);
Pob pob: lub pob yog tsau los ntawm lub sab saud thiab qis dua lub rooj valve yog qhov tsim nyog rau ultra-siab siab (ntau dua lossis sib npaug nrog PD420);
Sealing Form: carbide sealing (kub tiv taus 425 degree), PTFE mos foob (tsawg dua los yog sib luag rau qib vi mus txog Anski Vi.

Daim Ntawv Thov thiab Qauv Piv Txwv
Petrochemical: Tswj kev kub-thiab cov roj siab thiab cov acids (xws li Q41F {3}} p Cov stainless hlau pob valve); Zog thiab Pip: Chav Pipelines thiab Boiler Tshuab (xws li Bkh Series Pneumatic High-SIAB LAWV); HYDRAULIC SYSTEM: Cov Roj Tsheb Hluav Taws Xob Hydraulic (xws li Khb Yam High-Siab Carbon Steel Pob Valve); TSHWJ XEEB TSHAJ: Corrosive Gases (xws li 316L Stainless Hlau + Carbide Seal Ua ke).
Xaiv thiab Txhim Kho Cov Ntsiab Lus
Cov lus pom zoo: Kev Tsim Nyog Cov Kev Pom Zoo: Ua ntej ua ntej pob pob qauv + lub cim carbide, haum rau nquag qhib thiab cuam tshuam cov ntsaws; Corrosive Media: Xaiv 316 / 316L stainless hlau valve lub cev, lossis npib tsib xee-plated nto; Flange Txuj Ci: Ntaus Pipeline Flange Spirmicions (xws li ASME B16.5, HG / T20592). Cov ntsiab lus tshwj xeeb:
Cov Flange Bolts yuav tsum tau ua kom nruj kom tsis txhob muaj kev cuam tshuam ntawm lub cev valve thiab xau;
Lub VALVE STREAK operating chaw (ntau dua los yog sib npaug rau 90 degree) yuav tsum tau tshwj tseg, thiab pneumatic / fais actuator yuav tsum tau nruab nrog txoj kev txwv hloov.
