Steel Rooj vag Valve: A Bidirectional Zero-Leakage Sealing Solution for Demanding Service Conditions

Hauv cov kav dej tseem ceeb thoob plaws cov roj & roj, lub zog tsim hluav taws xob, thiab kev ua tshuaj lom neeg, kev xaiv valve ncaj qha cuam tshuam rau tag nrho kev ua haujlwm kev nyab xeeb thiab kev ua haujlwm. Hlau rooj vagvalves tau tsim lawv tus kheej los ua qhov kev xaiv tseem ceeb rau - txoj haujlwm tseem ceeb ntawm kev sib cais ntawm kab, vim yog lawv qhov zoo ntawm cov khoom muaj txiaj ntsig - tsis tshua muaj kev khiav hauj lwm tsawg, muaj peev xwm ua tau ob txoj kev khiav, thiab kev sib khi zoo.

Tsis zoo li lub pob lossis npauj npaim li qub, uas nws qhov kev sib khi feem ntau yog nyob ntawm qhov kev taw qhia ntws, siab - zoo cam khwb cia steel rooj vag li qub xa cov peev xwm kaw zoo tib yam hauv ob qho kev qhia. Qhov no ua rau lawv tsis tuaj yeem hloov pauv hauv cov kav dej sib txuas uas cov dej ntws rov qab tau nquag los yog rov qab - muaj kev pheej hmoo siab.

Khoom siv, qauv, thiab Rugged siv

Peb lub rooj vag steel yog engineered nyob rau hauv tag nrho ua raws li API 600 thiab ASME B16.34. Lub cev yog tsim los ntawm precision casting, siv WCB carbon steel los yog CF8 / CF8M stainless hlau qib, haum rau qhov kub thiab txias ntawm -29℃mus txog 570℃(khoom siv -nyob ntawm seb).

Sab hauv trim Cheebtsam muab 13Cr stainless hlau rooj zaum nrog saj zawg zog graphite packing, kom ntseeg tau tias seal kev ncaj ncees nyob rau hauv siab sib txawv siab. Rau cov diameters loj, peb txais yuav aflexible wedge rooj vag valvetsim-qhov geometry no tau txais txiaj ntsig zoo rau kev nthuav dav thermal ntawm lub cev ntawm qhov kub siab, tiv thaiv cov kab txuas. Qhov no tshwj xeeb tshaj yog ib qho tseem ceeb heev thaum tuav high -kub chav los yog thermal roj systems.

Specification Txheej txheem cej luam

Lub zog tseem ceeb: Flow Resistance, Flow Direction, thiab Seal Performance

Qhov tseem ceeb tshaj plaws ntawm asteel rooj vag valvelies nyob rau hauv nws tshwj xeeb tsis tshua muaj txaus tsis kam. Thaum lub npoo tau muab tshem tawm tag nrho ntawm txoj kev ntws, lub bore sab hauv ua ncaj nraim - dhau, puv - chaw nres nkoj hla - qhov tseem ceeb muab qhov kev tiv thaiv coefficient zero. Nyob rau hauv ntev -ntaub kis kab mob kis tau tus mob, qhov no txhais ncaj qha mus rau hauv lub zog txuag tseem ceeb rau cov twj thiab compressors.

Tsis tas li ntawd, qhov xwm txheej bidirectional txawv cov li qub los ntawm eccentric npauj npaim lossis kos li qub. Txawm hais tias siv cov khoom sib txuas -slide los yog wedge- hom discs, tus qauv tsim kom ntseeg tau tias sealing siab yog siv tib yam tsis hais txog kev khiav dej num. Nrog hardfaced alloy sealing nto, peb lub rooj vag li qub tuav nruj kaw txawm nyob rau hauv xov xwm uas muaj me me particulates, ua tiavANSI/FCI 70-2 Chav Kawm VIzero-kev ua tau zoo.

Pov thawj kev ua tau zoo nyob rau hauv Extreme Applications

Kev ntseeg ntawm pebsteel rooj vag li qubtau pom nyob rau hauv loj infrastructure tej yaam num thoob ntiaj teb. Piv txwv li, nyob rau hauv Tuam Tshoj -Russia Eastern Gas Pipeline (Heihe-Shanghai seem) ua los ntawm National Pipeline Network Group, muaj coob tus siab - siab, loj - tho welded cam khwb cia steel rooj vag li qub tau xa mus rau mainline cais thiab ceg coj - tawm chaw nres tsheb

Nyob rau hauv txoj kev no, lub raj xa dej hla cov cheeb tsam permafrost nrog qhov kub thiab txias hloov pauv, ua rau muaj kev xav tau huab cua ntawm ob qho tib si tsis tshua muaj kev ruaj ntseg thiab muaj zog sealing muaj peev xwm nyob rau hauv thermal cycling.

Peb cov kev daws teeb meem -featuring bidirectional hlau-rau-hlau sealing thiab tiv thaiv- hluav taws kub zoo-kev nyab xeeb tsim- tau ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm txoj kev tsim hluav taws xob txoj hauv kev. Cov ntaub ntawv taug qab no qhia txog peb cov kev txawj ntse tob hauv siab -siab ntev- daim ntawv thov kev sib kis.

Hom Daim Ntawv Thov Scenarios

• Roj & roj extraction- Cov rooj sib txoos hauv qhov dej, qhov chaw sib sau ua ke siab -kev sib cais siab.
• Ntev - kis tau tus mob- Mainline thiab tawm - nqa chaw nres tsheb thaiv li qub (yuav tsum muaj tag nrho -welded lossis txuas ntxiv bonnet tsim).
• Refining & tsim hluav taws xob- Siab -kub chav tshuab, boiler feedwater, thiab catalytic cracking units.
• Kev kho dej & mining- Loj - txoj kab uas hla dej loj, slurry tuav (nrog hnav- cov coatings resistant).

Thaum xaiv lub valve, nco ntsoov paub meej tias cov chav kawm siab ua haujlwm thiab cov yam ntxwv nruab nrab. Rau cam khwb cia steel rooj vag valve qhov ntev lossis kev txhawb nqa kev txhawb nqa ntawm cov haujlwm tshwj xeeb, thov hu rauCOVALVEpab pawg engineering.
