Rooj vag Valve Flanged kawg

Puas muaj qhov sib txawv loj ntawm flanged kev twb kev txuas thiab threaded screwed kev twb kev txuas ntawm lub rooj vag li qub?

Flanged kev sib txuas siv sib txuam flanges, bolts thiab gaskets los txuas cov kav dej thiab li qub. Lawv haum cov yeeb nkab loj diameters thiab high-pressure industrial kab. Disassembly rau kev kho yog yooj yim, thiab sealing kev ua tau zoo nyob ruaj khov mus ntev.

Threaded xaus ntsia hlau ncaj qha mus rau cov kav dej me me yam tsis muaj flanges. Lawv raug nqi tsawg dua thiab siv qhov chaw teeb tsa tsawg dua, tab sis tsuas yog haum me me, cov kab hluav taws xob tsis tshua muaj siab. Threaded pob qij txha yooj yim rau seepage nyob rau hauv siab kub thiab tawv ua hauj lwm tej yam kev mob, thiab yog tsis yooj yim sua kom sib cais tom qab.

Cov cwj pwm tseem ceeb

Puas yog nws zoo siv flanged gate li qub kom qeeb lossis kho cov dej ntws?

Peb tsis pom zoo kom throttling ntws nrog flanged rooj vag li qub txhua. Cov li qub no yog tsim los nruj heev rau lub xeev qhib lossis kaw tag nrho.

Khaws cov npoo ib nrab qhib cia kom nrawm nrawm nruab nrab tsis tu ncua cuam tshuam rau qhov chaw sib khi, uas yuav khawb thiab hnav lub rooj sai sai, ua rau muaj qhov tsis zoo mus tas li. Kev qhib ib nrab kuj ua rau muaj zog kev co thiab dej rauj uas ua mob rau lub valve thiab cov kav dej txuas. Globe li qub lossis pob li qub yog qhov tsim nyog dua yog tias xav tau kev hloov pauv.

Qhov loj npaum li cas thiab qhov ntsuas siab ua li cas Gate Valve Flanged End feem ntau tuaj hauv?

Cov nominal ntau thiab tsawg npog DN50 txog DN1200. DN80, DN100, DN150, DN200 thiab DN300 yog peb cov muag khoom loj tshaj plaws rau kev lag luam thiab hauv nroog.

Standard siab qib suav nrog ob lub hauv paus ntsiab lus:

GB txheem PN10, PN16, PN25, PN40; ANSI Chav Kawm 150, Chav Kawm 300, Chav Kawm 600.

PN16 thiab Chav Kawm 150 ua haujlwm rau feem ntau cov dej, chav dej thiab cov kav dej tshuaj lom neeg, thaum cov qib siab siab ua haujlwm siab-kub thiab petrochemical ua haujlwm scenarios.

Dab tsi yog cov ntaub ntawv raw khoom siv rau kev tsim flanged rooj vag li qub?

Valve lub cev thiab cov ntaub ntawv wedge yog xaiv raws li nruab nrab thiab kub:

WCB carbon steel: peb cov kev xaiv tseem ceeb, lub zog muaj zog rau cov roj tsis tu ncua, dej thiab nruab nrab-kub chav

SS304 / SS316 stainless hlau: tiv thaiv corrosion, zoo tagnrho rau cov kua dej thiab cov kav dej hiav txwv

Ductile hlau: kev lag luam xaiv rau cov dej tsis zoo hauv nroog

Cov khoom siv sib txawv sib txawv kuj sib xws: graphite packing rau high-temperature chav, RPTFE rau tsis muaj zog corrosive media, thiab Stellite nyuaj alloy rau hnav-resistant high-pressure sealing ntsej muag.

Peb yuav tsum ua raws li cov kauj ruam kev tu txhua hnub rau Gate Valves Flanged End?

Ua cov tshev yooj yim li niaj zaus tuaj yeem ua rau koj lub rooj vag valve kav ntev dua.

Nco ntsoov tias koj tsuas yog qhib tag nrho lossis kaw tag nrho lub valve, tsis txhob tso nws ib nrab qhib vim qhov no yuav hnav tawm lub foob sai.

Xyuas cov flange bolts txhua ob peb lub hlis. Tighten ib qho xoob xoob thiab hloov cov pa roj qub qub yog tias koj pom cov xau nyob ib puag ncig kev sib koom tes.

Muab cov roj nplua nyeem tshwj xeeb rau ntawm lub qia valve tam sim no thiab tom qab ntawd ces tus kov tig smoothly tsis tau daig.

Tshem plua plav thiab tshuaj lom neeg tsim tawm ntawm lub valve sab nraud kom tsis txhob xeb ua rau lub cev thiab flanges.

Yog tias lub valve tseem xau thaum kaw tag nrho, muab nws sib nrug los ntxuav lossis hloov cov ntaub qhwv thiab cov rooj zaum sib khi.

Yog tias lub valve yuav tsis siv ib ntus, cia nws qhib tag nrho thiab npog lub qia kom tiv thaiv nws los ntawm xeb thiab av.
