Flanged valve tau teeb tsa rau hauv cov kav dej kom muaj peev xwm kaw cov kua dej sai sai thiab tom qab lub cev qhuav dej ntawm qhov nruab nrab. Txhawm rau nce qib kev ruaj ntseg, cov ntsiab lus no nyob hauv txhua qhov chaw ntawm lub network.
Kev piav qhia
Flanged lub rooj vag valve ua raws li lub valve kaw thiab muaj tus qauv tsim yooj yim, txawm tias muaj kev ua haujlwm siab. Nws yog nyob rau hauv qeb ntawm kaw-tawm tsev kais dej thiab muaj ib tug tshwj xeeb thaiv qhov chaw nyob rau hauv nruab nrab ntawm cov qauv, nws kev tua nyob ntawm seb hom valve nws tus kheej. Qhov dav tshaj plaws yog disk xauv, wafer wedge thiab pob rotary ntsiab.
Lub flange valve tau txais nws lub npe vim yog cov flange tshwj xeeb nyob ntawm cov npoo. Lawv tau siv los muab kev nkag mus rau lub kaw lus ceev thiab muaj peev xwm tshem tawm cov khoom siv rau kev hloov lossis kho kev ua haujlwm. Nws yog tsim nyog sau cia tias qhov ntev ntawm lub mating flange keeb yuav tsum sib haum mus rau lub ntsiab phaj. Txwv tsis pub, kev sib txuas yuav tsis muaj qhov zoo, lossis nws yuav ua tsis tau txhua.
pros and cons
Ntawm cov ntsiab lus zoo, nws tsim nyog sau cov hauv qab no:
- kom muaj peev xwm kho tau sai lossis hloov lub cuab yeej nrog ib qho tshiab;
- simple;
- lub neej ua haujlwm ntev;
- qis hydraulic tsis kam;
- reliability.
Qhov tsis zoo yog qhov loj. Qhov no ua rau tus nqi siab ntawm cov ntsiab lus, tshwj xeeb tshaj yog cov loj loj, vim tias cov khoom siv loj heev xav tau rau lawv cov khoom siv. Tsis tas li ntawd tsim nyog sau cia yog qhov hnav ceev ceev ntawm cov ntsaws ruaj ruaj.
Ntau yam
Cov cam khwb cia hlau flanged rooj vag valve muaj nyob rau hauv ntau yam. Cov cuab yeej tau muab faib ua hom raws li cov kev taw qhia ntawm kev ua - parallel thiab perpendicular. Qhov kev xaiv tom kawg yog nyob ruaj ruaj thiab txuas mus rau qhov txuas mus rau lub ntsiab ntws. Parallel attachments mount ntawm xoom lub kaum sab xis thiab tsis cuam tshuam rau ntws thaum nyob rau hauv hom qauv.
Tseem muaj kev faib raws li tus qauv tsim - cov no yog lub rooj vag, pob thiab cov npoo zoo li cov ntsiab lus. Cov tom kawg yog kaw-off li qub ntawm ib hom qauv. Lawv ua tau zoo heev, muaj ib hom kev thaiv thaiv, tab sis hnyav.
Tus kheej kheej kheej kheej zoo ib yam li kaw cov khoom hauv tsev ntawm hom zoo sib xws. Cov cuab yeej siv dav tshaj plaws yog DU 50 vim lawv tus nqi qis. rooj vag valveflanged DN 100 muaj cov khoom tshwj xeeb uas kaw cov raj xa dej nrog lub caij nplooj ntoos hlav muaj zog. Raws li txoj cai, nws tau nruab rau ntawm cov kav dej thiab cov roj sib txuas.
Kev faib tawm los ntawm txoj kev tswj hwm:
- Handheld devices. Hom no yog tswj manually los ntawm tig ib tug tshwj xeeb kov los yog valve. Txawm hais tias lawv yuav tsum tau siv zog ntau rau lub cev, lawv yuav tsum tsis muaj kev saib xyuas thiab tsis tshua ua haujlwm.
- Cov khoom siv hluav taws xob. Nws muaj lub tshuab hluav taws xob built-in rau kev tswj. Lub kaw lus kaw autonomously, tom qab nias lub pob.
Cov haujlwm ua haujlwm
Flanged valve ua haujlwm hauv ntau qhov siab, qib siab tshaj plaws tuaj yeem ncav cuag ntau pua units. Kev khiav hauj lwm kub ntawm +200 txog -50 degrees. Cov hlau cam khwb cia yog tus cwj pwm los ntawm cov yam ntxwv txuas ntxiv, tshwj xeeb, ua haujlwm nrog cov khoom siv roj tuaj yeem tshwm sim ntawm +400 degrees, thiab cov kua nruab nrab thauj tuaj yeem muaj qhov kub ntawm +270 degrees Celsius.
Clinker flanged gate valve yog tsim los ntawm cov ntaub ntawv xws li cam khwb cia hlau thiab hlau. Qhov parameter no nyob hauv daim ntawv lo ntawm lub cuab yeej. Txhua yam khoom nruab nrog flanges yuav tsum tau ua tib zoo xaiv raws li qhov ntev, uas yog tswj los ntawm cov ntaub ntawv tshwj xeeb. Ua ntej ntawm tag nrho cov, lub diametrical loj ntawm lub conditional passage yog coj mus rau hauv tus account. Yog tias muaj qhov tsis sib xws nrog cov qauv no, kev sib txuas ua tsis tau. Yog siv rau installationflanged steel khoom nrog qhov loj ntawm DN 80 lossis DN 50, lub flange mus rau cov kav dej uas nyob ib sab yuav tsum muaj qhov tsis sib xws. Nyob rau tib lub sijhawm, flanged lub rooj vag valve, zawv zawg ntxaiv uas ua haujlwm hloov pauv hloov pauv thaum qhib, tuaj yeem ua rau ntau qhov ntau thiab tsawg. Qhov loj tshaj plaws tuaj yeem ncav cuag 1500mm, qhov me tshaj plaws rebar muaj txoj kab uas hla ntawm 25mm.
Scope of application
Cov ntsiab lus DN 80 thiab DN 50 feem ntau siv dav hauv cov kav dej nruab nrab thiab sab ceg ntawm cov tshuab. Tsis tas li ntawd, lawv tau siv rau hauv cov tshuab loj hauv tsev, cov ceg ntoo thiab hauv chav boiler. Lub flanged rooj vag valve 100 yog qhov loj dua thiab tau nruab rau ntawm cov cua sov thiab cov kav dej loj. DU 200 cov khoom siv tsuas yog nyob rau hauv kev lag luam tej yam kev mob ntawm lub siab lub ntsiab systems, thaum loj tshwj xeeb bolts yog siv rau lawv installation. Tus nqi ntawm fittings nyob ntawm ob qhov ntev thiab cov qauv tsim. Tus nqi ntawm cov khoom siv hauv kev tsim khoom kuj tseem ceeb.
Installation
Kev txhim kho cov khoom yog ua raws li tus qauv txheej txheem. Nyob rau tib lub sijhawm, kev ua haujlwm tau yooj yim los ntawm vuam flanges rau cov kav dej lossis li qub. Txwv tsis pub, cov neeg ua haujlwm yuav tsum tau txuas cov li qub ntawm nws tus kheej nrog cov khoom ntxiv thiab txuas cov yeeb nkab ib leeg. Cov txheej txheem no yuav tsum muaj nyiaj txiag loj thiab cov nqi sijhawm, thiab tseem muaj qee qhov teeb meem, qhov tsis ua haujlwm uas tuaj yeem ua tauua rau muaj teeb meem thaum ua haujlwm. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev lag luam.
Nrog kev pab los ntawm lub nplhaib roj hmab sealing, nruj yog nce. Nws yog ntsia rau hauv ib lub channel nyob rau ntawm lub phaj flange. Nyob rau sab pem hauv ntej ntawm lub phaj yuav tsum tsis muaj scuffs thiab lwm yam kev puas tsuaj, txwv tsis pub muaj peev xwm ntawm depressurization thiab ib tug breakthrough ntawm lub system. Nyob rau hauv cov xwm txheej ntawm kev ua hauj lwm nrog kev kub siab, qhov no yog fraught nrog loj txim.
