Valves

Valves thiab Manifoldyog cov khoom tseem ceeb hauv cov roj thiab cov kav dej hauv cov kav dej thiab cov khoom siv siab hauv cov chaw petrochemical, ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo dua thiab kev ua haujlwm petrochemical. Lawv cov haujlwm tseem ceeb suav nrog: qhib / kaw qhov nruab nrab ntws; tswj nruab nrab siab thiab ntws tus nqi; sib cais, sib tov, lossis faib cov khoom nruab nrab; tiv thaiv nruab nrab siab los ntawm kev tshaj tawm tus nqi kom muaj kev nyab xeeb ntawm cov kav dej thiab cov khoom siv ua haujlwm, thiab lwm yam.

 

Muaj ntau hom muaj nyob ntawm qhov sib txawv ntawm cov kua dej, qhov kub thiab txias, thiab cov khoom siv physico-chemical uas yuav tsum tau ua kom muaj kev tswj hwm sib txawv. Rooj vag, Choke, kos, thiab Plug valve muaj cov ntawv thov dav tshaj plaws.

Qhib / kaw cov kua dej ntws nrog qhov tsis muaj zog, kev sib khi zoo, tsis muaj kev txwv tsis pub khiav, thiab kev ua haujlwm me me rau lawv cov qauv luv.

Nws cov stems muaj qhov nce thiab tsis nce. Rising stems nplua corrosive cov kev pab cuam thaum uas tsis yog-nce sawv daws yuav mas siv nyob rau hauv cov kav dej rau tsawg-siab, tsis-corrosive media xws li

Lub rooj vag phaj cov qauv muaj xws li cov npoo thiab cov kab sib txuas.

Wedge daim hlau muaj ib qho thiab ob lub qhov rooj variants. Cov rooj vag sib npaug feem ntau siv hauv cov roj / roj tsheb thauj mus los thiab tsis tshua muaj nyob hauv cov nroj tsuag tshuaj.

(2) Lub pob valve

Siv rau qhib / tawm. Piv nrog rau cov khoom siv rooj vag, lawv muaj cov kua dej ntau dua thiab kev ua haujlwm torque tab sis kuj muaj cov kev xav tau ntawm cov dej ntws.

◆ Qhov zoo:

(1) Tsawg foob kev sib txhuam thaum qhib / kaw, ua rau hnav tsis kam.

(2) Qhov siab qhib qis dua.

(3) Nws feem ntau tsuas muaj ib qho chaw foob, ua kom yooj yim rau kev tsim khoom thiab kev saib xyuas.

Raws li lub cev configurations, nws muaj inline, lub kaum sab xis, thiab Y-hom variants. Inline muaj cov ntawv thov dav tshaj plaws thaum lub kaum sab xis siv rau 90 degree ntws kev hloov pauv.

(3) Tshawb xyuasValves

Kuj hu ua qhov tsis rov qab los yog ib txoj kev valve, tiv thaiv kev thim rov qab. Xyuas kom tseeb tias cov dej ntws ntws tau muab tso ua ke sib phim lub xub valve. Ntau hom muaj nyob nrog qhov sib txawv ntawm cov tuam txhab tsim khoom, tab sis lawv tau muab faib ua cov qauv nqa thiab viav vias hom. Lift checks muaj xws li ib leeg thiab ob lub flap variants.

(4) Plug valve

Nws muaj cov dej tsis zoo, sealing zoo, lub neej ua haujlwm ntev, thiab bidirectional sealing haum rau cov khoom siv phom sij heev. Txawm li cas los xij, lawv muaj lub zog ua haujlwm siab dua thiab tus nqi. Lawv cov kab noj hniav tsis sib xyaw kom tsis txhob muaj kab mob hauv cov chaw ua haujlwm. Yog li ntawd, nws yog tsim nyog nyob rau hauv ib co kev siv.

(1) Vigor muab cov saum toj no dav siv valve, tag nrho raws li API 6A nrog zoo zoo thiab kev sib tw kom zoo dua.

(2) Product Specification Level (PSL) rau rooj vag valve: 1-3, rau tag nrho lwm yam khoom: 1-4

(3) Khoom siv: AA-FF

(4) Kev Ua Tau Zoo (PR): 1-2.

(5) Ua Haujlwm Siab: 2000PSI-15000PSI

Valve cov ntaub ntawv muaj xws li lub cev, internals, gaskets, packing thiab fasteners, thiab lwm yam. Qhov no qhia txog lub cev valve cov ntaub ntawv uas muaj cam khwb cia hlau, carbon hlau, stainless hlau, thiab hlau alloy.

(1) Cam khwb cia hlau

Grey cam khwb cia hlau (A126-2B) feem ntau yog siv nyob rau hauv qis-siab valve thiab tsis pom zoo rau cov txheej txheem kav. Nodular cam khwb cia hlau (A395) muaj lub zog zoo dua thiab tawv dua li grey cam khwb cia hlau.

(2) Carbon hlau

Cov khoom siv carbon steel feem ntau yog A216-WCB (casting) thiab A105 (forging). Nco ntsoov cov kev pabcuam carbon steel saum 400 degree ua rau lub neej luv luv. Rau cov kev pabcuam kub qis, cov khoom siv yog A352-LCB (casting) thiab A350-LF2 (forging).

(3) Austenitic Stainless hlau

Austenitic stainless steels feem ntau yog siv rau hauv cov kev pabcuam corrosive lossis cryogenic xws li castings - A351-CF8, A351-CF8M, A351-CF3, A351-CF3M thiab forgings - A 182-F304, A182-F316, A182-F304L, A182-F316L.

(4) Alloy hlau

Rau cov kev pabcuam kub qis, A352-LC3 (casting) thiab A350-LF3 (forging) feem ntau yog siv thaum A217-WC6 (casting), A182-F11 ( forging), thiab A217-WC9 (casting), A182-F22 (forging) yog siv rau cov kev pabcuam kub kub. Txij li thaum WC9 thiab F22 muaj ntau Cr thiab Mo tshaj 1-1/4Cr-1/2Mo WC6 thiab F11, lawv muaj kev nkag tau zoo dua ntawm qhov kub thiab txias.

(2) Kev ua haujlwm yuav tsum tau ua (tswj lossis qhib / tawm) feem ntau cuam tshuam rau hom valve.

(3) Kev khiav hauj lwm tej yam kev mob (ntau zaus) cuam tshuam valve hom thiab cov khoom.

(4) Flow yam ntxwv thiab kev sib txhuam poob.

(5) Valve loj muaj rau qhov loj me.

(6) Cov kev cai tshwj xeeb xws li kev kaw thaum muaj xwm txheej ceev, sib npaug siab.

Ntawm Vigor,Valves thiab Manifoldyog peb lub siab nyiam thiab kev txawj ntse. Peb muab cov khoom muaj txiaj ntsig zoo, kev ua haujlwm siab.
