API 594 Dual plate check valve siv rau cov kav dej ntshiab thiab kev lag luam, kev tiv thaiv ib puag ncig, kev kho dej, kev muab dej thiab cov kav dej ntws hauv cov tsev siab kom tiv thaiv kev ntws rov qab ntawm cov xov xwm. Lub check valve siv hom wafer, lub phaj npauj npaim yog ob lub voj voog, thiab siv lub caij nplooj ntoos hlav los yuam kom rov pib dua, qhov chaw sealing tuaj yeem yog lub cev surfacing vuam hnav-resistant khoom lossis roj hmab hauv ob sab phlu, ntau yam kev siv yog dav, thiab kev sealing yog txhim khu kev qha.

Qhov qhib thiab kaw ntawm API 594 lub qhov dej xyuas vam khom qhov ntws thiab lub zog ntawm cov khoom nruab nrab kom qhib lossis kaw lawv tus kheej kom tiv thaiv cov khoom nruab nrab kom tsis txhob ntws rov qab. Lub qhov dej hu ua lub qhov dej xyuas. Cov qhov dej xyuas yog cov khoom siv tsis siv neeg, uas feem ntau yog siv rau hauv cov kav dej uas cov khoom nruab nrab ntws mus rau hauv ib qho kev taw qhia, thiab tsuas yog tso cai rau cov khoom nruab nrab ntws mus rau hauv ib qho kev taw qhia kom tiv thaiv kev sib tsoo.

Raws li cov qauv ntawm lub valve, nws muaj peev xwm muab faib ua peb hom:nqa lub valve xyuas, lub qhov rooj valvethiabwafer check valveCov li qub uas tsa tau muab faib ua ob hom: ntsug thiab kab rov tav. Cov li qub uas tig tau muab faib ua peb hom: ib lub li qub, ob lub li qub thiab ntau lub li qub. Lub li qub uas tig tau yog hom ncaj. Lub li qub uas tig tau yog lub li qub uas tuaj yeem tiv thaiv cov kua dej kom tsis txhob ntws rov qab. Lub hau ntawm lub li qub yuav qhib raws li qhov siab ntawm cov kua dej, thiab cov kua dej yuav ntws los ntawm sab nkag mus rau sab tawm. Thaum qhov siab ntawm sab nkag qis dua qhov siab ntawm sab tawm, lub li qub yuav kaw raws li qhov sib txawv ntawm qhov siab ntawm cov kua dej, lub ntiajteb txawj nqus thiab lwm yam los tiv thaiv cov kua dej kom tsis txhob ntws rov qab.

Kev paub txog kev ua haujlwm ntawm API 594 check valves

Tus Qauv API 594 yog dab tsi?

API 594, tsim los ntawm American Petroleum Institute (API), yog tus qauv kev lag luam tseem ceeb hu ua "Check Valves: Flanged, Lug, Wafer, thiab Butt-welding Types." Cov lus qhia tseem ceeb no tswj hwm kev tsim qauv, kev xaiv khoom siv, qhov loj me ntawm cov qauv, kev kam rau siab-kub, thiab kev tshuaj xyuas / kev sim cov txheej txheem rau cov check valves hauv kev lag luam.

Scope & Daim Ntawv Thov ntawm API 594

API 594 siv rau ob qho tib si Hom A (lub ntsej muag luv) thiab Hom B (lub ntsej muag ntev). Nws npog tag nrho ntau yam qauv tsim, suav nrog:

• Cov Vev Xaib Tshawb Xyuas Viav
• Nqa Cov Li Qub Tshawb Xyuas
• Dual Phaj Tshawb Xyuas Valve /Wafer Kos Valves
• Npauj Npaim Tshawb Xyuas Valves
  Tus qauv no siv tau rau qhov loj ntawm lub valve txij li DN 150 (NPS 6) txog DN 400 (NPS 16). Nws tswj cov valve uas ua los ntawm cov ntaub ntawv xws li grey cast iron, ductile iron, carbon steel, stainless steel, thiab lwm yam alloys.

API 594 Tsim & Cov Khoom Siv Yuav Tsum Tau

• Kev Tsim Ua Raws Cai: Kev tsim lub valve yuav tsum ua raws li API 594 cov lus qhia.
• Cov Qauv Kev Sib Txuas: Cov kev sib txuas kawg (flanged, lug, wafer, butt-weld) yuav tsum ua raws li qhov ntev thiab kev ntsuas uas tau teev tseg hauv cov qauv uas tau hais txog xws li ASME B16.11 (Socket Welding & Threaded) thiab ASME B16.15 (Cast Bronze Threaded Fittings - Class 125 & 250).
• Kev Xaiv Khoom Siv: Cov khoom siv lub cev uas raug tso cai suav nrog cov hlau grey cast, hlau ductile, hlau carbon, hlau stainless, thiab ntau yam alloys. Qhov tseem ceeb, cov khoom siv ntawm qhov chaw sealing yuav tsum sib xws nrog cov khoom siv tshwj xeeb kom ntseeg tau tias muaj kev ruaj khov thiab tiv thaiv kev xeb lossis kev puas tsuaj.

Cov Qauv Valve & Cov Txheej Txheem Txuas

API 594 faib cov li qub raws li lawv qhov kev sib txuas kawg:

• Hom Flanged: Siv cov kawg flanged rau kev sib txuas bolted rau cov yeeb nkab flanges. Zoo tagnrho rau cov qauv flange piping systems uas xav tau yooj yim sib dhos/rho tawm.
• Hom Vuam Taub: Muaj cov qhov kawg uas nkhaus rau kev vuam ncaj qha rau cov kav dej. Tsim los rau kev siv kub siab, siab siab, lossis kev pabcuam tseem ceeb uas qhov kev ruaj khov ntawm qhov xau yog qhov tseem ceeb.
• Hom Lug: Muaj cov xov ntxig (lugs) rau ntawm lub cev valve, ua kom muaj kev teeb tsa ntawm cov flanges siv bolts los ntawm cov lugs, tsim nyog rau kev pabcuam tuag-kawg.
• Hom Wafer: Muaj qhov tsim me me, sib dua uas tau teeb tsa ntawm cov flanges siv cov ntsia hlau ntev uas hla tag nrho cov kav dej. Siv qhov chaw zoo rau cov kav dej lag luam.

Kev Ntsuas Kub thiab Siab

API 594 txhais cov qib siab-kub (PT) rau cov kav dej kuaj xyuas raws li cov khoom siv, kev tsim qauv, thiab qhov loj me. Cov qib no lav tias lub valve tuaj yeem ua haujlwm tau zoo thiab ntseeg tau hauv qab qhov kub thiab txias thiab siab uas tau teev tseg thoob plaws nws lub neej ua haujlwm. Cov neeg tsim qauv thiab cov neeg ua haujlwm yuav tsum ua raws li cov kev txwv PT no.

Kev Tshuaj Xyuas & Kev Ntsuas Cov Kev Cai

Txhua lub API 594 check valves yuav tsum tau kuaj xyuas thiab sim kom paub tseeb tias ua haujlwm tau zoo thiab ruaj khov. Cov txheej txheem kuaj xyuas ua raws li cov qauv kev lag luam, feem ntau yog:

• API 598: Kev Tshuaj Xyuas thiab Kev Ntsuas Valve (suav nrog kev kuaj plhaub, kev kuaj lub rooj zaum, kev kuaj lub rooj zaum tom qab, thiab lwm yam).
• ASME B16.10: Lub ntsej muag-rau-Lub ntsej muag thiab qhov kawg-rau-Qhov kawg ntawm cov li qub.
  Cov kev ntsuam xyuas tseem ceeb suav nrog:
• Kev Ntsuas Lub Zog ntawm Lub Plhaub: Xyuas kom meej tias lub cev muaj zog thiab lub hau npog ruaj khov.
• Kev Ntsuas Qhov Xaus Ntawm Lub Rooj: Paub meej tias lub peev xwm kaw ntawm lub tshuab kaw.
• Kev Ntsuas Kaw Siab: Xyuas kom meej tias kaw tau raws li qhov siab ntsuas.
• Kev Ntsuas Kaw Qhov Siab Qis: Xyuas kom meej tias kaw tau zoo nyob rau hauv qhov siab tsawg kawg nkaus.
• Kev Ntsuas Lub Rooj Tom Qab (yog tias siv tau): Txheeb xyuas qhov kev sib khi ntawm lub qia hauv qab qhov siab thaum lub valve qhib tag.
