Industrial Gate Valves: Lawv yog dab tsi, hom thiab kev siv tswv yim

Yog tias koj tshiab rau kev lag luam xws li roj thiab roj, lub zog tsim hluav taws xob, lossis kev kho dej thiab xav kawm txog cov txheej txheem tswj cov kua dej, cov rooj vag kev lag luam uas peb tab tom tham hnub no yog qhov koj yuav tsum nkag siab kom meej.

 

Txawm hais tias tej zaum koj yuav tsis tau pom lossis tsis hnov ​​​​txog lawv ua ntej, lawv yog cov feem ntau siv cov dej tswj cov khoom hauv cov kav dej. Lawv feem ntau ua kom tag nrho - ntws hla lossis kaw tag - tawm ntawm cov kua, roj, thiab lwm yam xov xwm, ua lub luag haujlwm hloov tsis tau hauv ntau qhov xwm txheej.

 

Ua ntej, cia peb npog qhov tseeb qhov tseeb: raws liValve ntiaj teb, ib tug thawj coj thoob ntiaj teb valve phau ntawv journal, kev lag luam rooj vag li qub yog linear motion li qub. Lawv lub hauv paus ntsiab lus ntawm kev khiav hauj lwm yog ncaj nraim: lub rooj vag (uas tuaj yeem pom tau zoo li cov hlau disc) hauv lub cev lub cev txav mus los thiab nqis mus rau qhov kev taw qhia ntws los tswj cov dej ntws.

 

Rau cov neeg tsis paub nrog lwm cov li qub, qhov sib txawv me ntsis: tsis zoo li lub ntiaj teb li qub, uas tswj tus nqi ntws,industrial rooj vag valvestsuas yog ua "tag nrho qhib" lossis "tag nrho kaw" ua haujlwm- txawm tias tso cai rau cov kua dej uas tsis muaj kev cuam tshuam lossis cuam tshuam tag nrho. Qhov no yog lawv tus yam ntxwv tseem ceeb.

 

Dab tsi yog qhov Industrial Gate Valves?

Rau cov neeg uas tsis tau pom lub rooj vag valve, ib qho piv txwv yooj yim pab: nws ua zoo li "sluice gate" ntsia rau hauv cov kav dej, zoo ib yam li cov hauv paus ntsiab lus rau cov sluices reservoir lossis cov rooj vag hauv zej zog, tab sis me dua, meej dua, thiab tshwj xeeb tsim los rau cov kav dej kav dej.

 

Thaum cov kua dej (dej, roj, chav, thiab lwm yam) yuav tsum tau ntws thaum lub sij hawm tsim khoom, lub "qhov rooj" ( rooj vag disc) yog tag nrho lifted, tso cai rau cov kua dej du nrog tsawg kawg nkaus tsis kam thiab tsis muaj kev cuam tshuam rau kev tsim khoom. Thaum ntws yuav tsum nres -rau cov khoom siv tu lossis kev tsim khoom kaw- lub rooj vag tau qis dua los ua lub foob kaw ntom nti tiv thaiv lub rooj zaum valve, tiv thaiv kev xau, kev nyab xeeb, thiab cov khoom pov tseg.

 

Qhov no yooj yim thiab siv tau tsim ua rau lawv dav siv nyob rau hauv ntev - kis tau tus mob pipelines thiab siab - ib puag ncig siab.

Cov ntsiab lus tseem ceeb rau cov neeg kawm thawj zaug -:industrial gate valves tsis haum rau kev tswj kev khiav dej num (throttling).Raws li hais meej nyob rau hauv lubPhau ntawv Journal of Pressure Vessel Technologyluam tawm los ntawm American Society of Mechanical Engineers (ASME), ntev - lub sij hawm qhib ib feem nthuav tawm cov rooj vag thiab cov rooj zaum mus tas li erosion los ntawm siab - cov kua dej nrawm, ua rau ntxov ntxov hnav, kev co, thiab txawm valve tsis ua hauj lwm uas cuam tshuam rau tag nrho cov raj xa dej - ib qho yuam kev ntawm cov pib tshiab.

 

Feem ntauHom ntawm Industrial Gate Valves

Tom qab nkag siab txog cov hauv paus, koj yuav xav tias lawv txhua tus zoo ib yam. Qhov tseeb, kev lag luam rooj vag li qub tau muab cais los ntawm cov qauv tsim, txhua tus muaj cov yam ntxwv tshwj xeeb rau kev ua haujlwm sib txawv. Hauv qab no yog cov hom tshaj plaws uas tau piav qhia hauv cov lus yooj yim.

1. Wedge Gate Valves

Feem ntau siv hom kev lag luam rooj vag valve.Nws lub ntsiab tseem ceeb yog ib lub voj voog - zoo li lub rooj vag. Thaum kaw, cov kua siab ua kom lub foob ntawm lub rooj vag thiab lub rooj zaum, tsim kom muaj ib qhotus kheej- sealing effectuas tiv thaiv kom tsis txhob tawg. Nws yog qhov zoo tagnrho rau siab -siab, siab - qhov chaw kub xws li cov kav dej thiab cov roj xa mus.

 

Wedge rooj vag li qub tau muab faib ntxiv rau hauv:

• Rigid wedge
• Flexible wedge(zoo dua thermal expansion / contraction adaptability, tsis txhob jamming)
• Sib cais

 

2. Parallel Gate Valves

Tsis zoo li cov rooj vag qhov rooj, lawv siv ob lub rooj sib txig sib luag nrog cov qhov rooj lossis cov txheej txheem sib kis. Cov rooj vag tsis txhob nias rau ib leeg, ua rau muaj kev hnav tsis zoo, ua rau lawv tsim nyog rau kev siv qis - siab xws li cov kav dej hauv nroog.

 

Muaj ntau qhov sib npaug ntawm qhov rooj vag valvetsis siv neeg lub rooj zaum hnav them nyiaj, ncua kev pab cuam lub neej thiab txo kev hloov zaus.

 

3. Rising Stem vs. Non-Rising Stem Gate Valves

Muab faib los ntawm qia (tus "tswj pas nrig" uas nqa / txo lub rooj vag) txav:

• Rising qia rooj vag Valves: Lub qia txuas mus rau sab saud thaum lub valve qhib, tso cai rau kev soj ntsuam ncaj qha ntawm txoj haujlwm qhib rau cov tswv teb.
• Tsis yog -Rising Stem Gate Valves: Lub qia tsis nthuav dav, tsim kom muaj kev sib cog lus zoo tshaj plaws rau cov kav dej hauv av thiab cov chaw kaw.

 

Core Applications ntawm Industrial Gate Valves

Raws li ib qho tseem ceeb ntawm kev tswj cov kua dej, cov rooj vag muaj kev lag luam yog qhov tseem ceeb hauv kev lag luam tseem ceeb, ntsiag to txhawb kev ua haujlwm ruaj khov txawm tias tsis pom.

 

Roj & Roj Kev Lag Luam: Siv rau kev sib cais ntawm lub taub hau thiab lub kav dej loj kaw -tawm.Tag nrho -port gate valvestau siv dav dav, ua kom yooj yim ntawm kev ntxuav cov cuab yeej thaum ua haujlwm pigging.

 

Fais fab nroj tsuag: Forged steel rooj vag li qubfeem ntau ntsia tau rau hauv lub ntsiab chav cais thiab boiler feedwater pipelines, tiv taus siab -siab, siab - kub.

 

Water Treatment & Municipal Engineering: Tsis yog- nce qia li qub cais tawm thaum lub sij hawm kho cov cuab yeej hauv cov twj tso kua dej thiab cov chaw kho dej khib nyiab, ua kom muaj kev nyab xeeb.

 

Kev ua tshuaj lom neeg: Stainless hlau rooj vag valvestiv thaiv corrosive media, tswj kev ruaj ntseg thiab ruaj khov ntau lawm.

Yuav Ua Li Cas Xaiv Txoj Cai Industrial Gate Valve

Xaiv txoj cai valve tsuas yog xav tau peb qhov tseem ceeb:

• Hom Nruab Nrab: Xaiv cov khoom raws li cov kua xa tawm -stainless steel rau corrosive media.
• Siab & Kub: Match valve ntsuas rau pipeline khiav hauj lwm siab thiab kub.
• Qhov chaw nruab: Xaiv qhov nce siab kom pom tau yooj yim, tsis yog - nce qia rau thaj chaw kaw.

 

Kev ceeb toom tseem ceeb: ib txwm ua raws li cov qauv thoob ntiaj teb xws liAPIthiabASME. Raws li tau sau tseg hauvVALVEcov ntawv xov xwm, kev ua raws cai ncaj qha cuam tshuam rau kev ua haujlwm hauv lub neej thiab kev nyab xeeb ntawm kev lag luam, thiab yuav tsum tsis txhob raug saib xyuas hauv kev yuav khoom lossis kev xaiv.
