Ob Chav Disc Gate Valves Ua Haujlwm li cas? Parallel Slide Gate Valve

Ob chav Disc rooj vag Valveyog ib hom valve uas ua tiav qhov yuam kev sib khi los ntawm kev nthuav dav ntawm axial ntawm ob lub rooj vag ywj pheej, thiab tau siv dav hauv lub zog, kev txuag dej, thiab kev lag luam tshuaj. Tsis zoo li cov rooj vag rooj vag ib txwm muaj, nws cov txiaj ntsig tseem ceeb suav nrog xoom bidirectional - leakage sealing thiab thermal expansion self- adaptability.

Cov qauv thiab cov txheej txheem ua haujlwm
▶️ Ob chav discs yog txuas nrog lub nruab nrab expansion mechanism (xws li ib tug wedge block, caij nplooj ntoos hlav, los yog floating pob lub rooj). Thaum lub valve raug kaw, lub qia txav mus rau hauv lub expansioner, yuam ob lub disc kom nthuav dav mus rau lub rooj zaum ntawm txhua sab.

Txhua lub disc ntawm nws tus kheej tiv tauj lub rooj zaum, tsim cov kab foob zoo ib yam li cov swb sib luagrooj vag valve. Cov txheej txheem no tshem tawm qhov kev pheej hmoo ntawm dhau - wedging ntawm ib qho disc - kaw torque yog raug xa mus raws li kev sib khi siab es tsis yog poob raws li qia thrust.

Qhov tseem ceeb Parameter:CovCOVALVEOb chav disc lub rooj vag valve muaj qhov nominal siab ntau ntawm PN16 ~

▶️PN100 thiab ib txoj kab uas hla ntawm DN50 ~ DN1200. Lub sealing leakage tus nqi ua raws li API 598 tus qauv (zero pom leakage). Lub rooj zaum yog hardfaced nrog Stellite alloy los yogInconel, haum rau xov xwm kub ntawm -29℃mus rau 650 degree.

Qhov zoo tshaj lwm yam
▶️Piv rau lub qhov rooj nthuav dav, ob chav disc qauv tso cai rau lub expander kom thim rov qab ua ntej thaum qhib, yog li cov discs tshem tawm ntawm lub rooj zaum ua ntej lifting vertically, zoo heev txo cov sealing nto kev sib txhuam. Qhov no ua rau lub valve haum rau kev ua haujlwm tsis tu ncua lossis kev tshaj tawm uas muaj cov khoom seem (xws li dej phwj, slurry). Nyob rau tib lub sijhawm, nws qhov ntxaib disc lub rooj vag valve tsim tso cai rau cov discs kom muaj kev sib khi tsis tu ncua tshwj xeeb thaum lub raj xa hluav taws xob thermal expansion lossis siab hloov pauv, tiv thaiv kev sib tsoo.

Cov ntaub ntawv siv tau: Hangzhou West Lake Pumping Station
☑️Nyob rau xyoo 2021, Hangzhou West Lake Pumping Station xaiv COVALVE ob lub qhov rooj qhov rooj li qub (qauv DDGV-16Q, DN800) thaum lub sijhawm nws txoj haujlwm kho dua tshiab. Qhov nruab nrab nyob rau hauv lub twj tso kua mis qhov hluav taws xob pipeline muaj ib tug me me ntawm sediment, thiab lub valve ua 6-8 zaug ib hnub twg.

Tom qab 18 lub hlis ntawm kev ua haujlwm tas mus li, tsis muaj qhov tso tawm sab hauv lossis disc jamming tshwm sim. Ntawm -cov ntaub ntawv saib xyuas qhov chaw qhia tau hais tias tus kheej - ntxuav scraping nyhuv ntawm ob lub discs (tsis siv neeg tshem tawm cov deposits ntawm lub rooj zaum nto thaum lub sij hawm disc txav) txo cov zaus txij nkawm. Piv nrog rau thawj lub rooj vag valve, tus txiv neej tu txhua xyoo - teev tau txo los ntawm 62%.

☑️Cov ntaub ntawv no txheeb xyuas qhov kev ntseeg tau ntawm qhov sib npaug ntawm lub qhov rooj vag valve hauv kev ua haujlwm hnyav thiab muab cov ntaub ntawv muaj txiaj ntsig rau kev xaiv cov khoom siv rau kev txuag dej.
