Product Overview
OS&Y (Sab nraum Ntsia Hlau thiab Yoke) Rising Stem Gate Valves yog tsim los rau hnyav -lub luag haujlwm ntawm / tawm kev cais nyob rau hauv siab - siab chav, roj, roj, thiab tshuaj kab. Los ntawm kev ua kom cov qia threads sab nraum qhov ntws, cov txheej txheem kev khiav hauj lwm yog cais tawm ntawm cov txheej txheem dej corrosion thiab cov khoom khib nyiab.
Qhov pom qhov nce siab muab kev pom tseeb tam sim ntawm qhov chaw valve los ntawm qhov deb, txaus siab rau qhov tseem ceeb ntawm kev nyab xeeb rau cov refineries, fais fab nroj tsuag, thiab kev lag luam piping headers.
Cov yam ntxwv tseem ceeb ntawm OS & Y Rising Stem Gate Valve
Visual Stem Position Indicator
Cov ceg nce siab muab cov kab tam sim - ntawm - pom qhov tseeb ntawm qhov qhib / kaw valve.
Tiv Thaiv Sab Nraud Kab Xov
Cov xov ua haujlwm tseem nyob sab nraum cov kua dej los tiv thaiv qhov nruab nrab -induced corrosion thiab xov seizing.
Tsawg-Txoj Siab-Tso Kev rho tawm
Tag nrho -chaw nres nkoj ncaj- los ntawm kev tsim ua kom muaj kev ua haujlwm siab tshaj plaws nrog kev kub ntxhov tsawg.
Customized Metallurgies thiab Trims
Cov khoom siv lub cev thiab cov rooj zaum yog sib npaug rau qhov kub thiab txias, siab, thiab dej chemistry.
Flanged thiab Welded kev sib txuas
Tsim los rau thoob ntiaj teb lub ntsej muag - mus rau - lub ntsej muag thiab xaus kev sib txuas qhov ntev rau poob - nyob rau hauv hloov.
Certified Pressure Testing
Txhua lub valve raug kuaj xyuas hydrostatic thiab plhaub nrog cov ntawv pov thawj zeb muab rau ib qho kev txiav txim.
Txoj Cai Ua Haujlwm
Ib qho OS&Y nce qia rooj vag valve tswj cov kab ntws los ntawm kev txav ib lub rooj vag vertically hla txoj hauv dej sab hauv.
Tig lub tes log tig lub txiv ntoo sab nraud, tsav qhov tsis yog -rotating qia upward los yog downward. Thaum qhib, lub qia nqa lub npoo tag nrho tawm ntawm cov kwj deg, tsim kom muaj txoj hauv kev ncaj nrog qhov tsis txaus ntseeg tsis txaus.
Thaum kaw, lub qia quab yuam cov npoo mus rau hauv lub valve lub cev lub rooj zaum los ua kom nruj, xau- pov thawj foob. Vim hais tias cov qia threads nyob sab nraum cov kua chamber, lawv tuaj yeem raug tshuaj xyuas thiab lubricated thaum lub sijhawm ua haujlwm niaj hnub yam tsis muaj kev cuam tshuam txaus.

FAQ
Q: Dab tsi yog OS & Y sawv rau hauv valve engineering?
A: OS & Y stands rau Sab Nrauv Ntsia Hlau thiab Yoke. Nws piav qhia txog tus qauv tsim uas cov qia threads nyob sab nraum cov kua dej -wetted chamber, tiv thaiv kev khiav hauj lwm cov khoom los ntawm cov kua dej sab hauv.
Q: Vim li cas OS&Y rooj vag li qub thiaj nyiam rau kev nyab xeeb - cov kav dej tseem ceeb?
A: Sab nraud nce qia ua raws li qhov taw qhia lub cev. Cov neeg khiav dej num tuaj yeem pom qhov pom tseeb tam sim ntawd seb puas muaj kab qhib tag nrho, kaw tag nrho, lossis cais yam tsis muaj kev ntsuas phau ntawv.
Q: Puas yog OS & Y Gate Valve siv tau rau kev ntws tawm?
A: Tsis yog. Rooj vag li qub yog tsim los nruj heev rau tag nrho - qhib lossis tag nrho - kaw kev pabcuam. Kev khiav hauj lwm nyob rau hauv ib feem qhib txoj hauj lwm ua rau lub rooj yaig thiab kev co loj heev vim muaj dej turbulent ntws.
Q: Cov rooj vag li qub no puas muaj ntawv pov thawj rau API 600?
A: Yog. Valves tuaj yeem teeb tsa, tsim, thiab sau tseg kom ua tau raws li API 600 cov cai, suav nrog phab ntsa thickness, qia taub, thiab cov qauv tsim.
Q: Cov ntsiab lus dab tsi yuav tsum tau txais kom tau txais cov lus qhia tseeb?
A: Thov qhia qhov loj ntawm lub valve (NPS / DN), qhov ntsuas siab (Class / PN), lub cev thiab cov khoom siv trim, hom kev sib txuas kawg, kev ua haujlwm kub, dej nruab nrab, thiab cov qauv tsim tsim.
