Dab tsi yog qhov txawv: Sluice Valve vs Scour Valve?

Hauv kev siv dej thiab dej engineering,lub valvethiabscour valvefeem ntau tsis meej pem, tab sis lawv yog qhov sib txawv hauv kev tsim lub hom phiaj, kev ua haujlwm logic, thiab txoj haujlwm teeb tsa. Kev paub qhov txawv ntawm lawv ncaj qha cuam tshuam rau kev nyab xeeb kev ua haujlwm thiab kev saib xyuas kev ua haujlwm ntawm cov raj xa dej.

1. Core Function – Cov haujlwm tseem ceeb sib txawv

✅A lub valveyog ib txoj kab tawm -kev tawm suab cais tawm uas nws cov tswvcuab kaw (lub rooj vag) txav vertically raws li qhov nruab nrab ntawm lub rooj zaum valve. Nws lub luag haujlwm tseem ceeb yog qhib lossis kaw tag nrho cov dej ntws hauv cov raj xa dej, siv rau kev cais cov kav dej los yog cov khoom siv, tsis yog rau kev khiav dej num.

Raws li BS 5163 thiab ISO 7259 tus qauv, sluice li qub rau cov khoom siv dej feem ntau yog tsim los rau "tag nrho qhib lossis kaw tag nrho". Lub sijhawm qhib ib nrab yuav ua rau kom yaig hnav ntawm lub rooj vag thiab lub rooj zaum.

✅A scour valveNtawm qhov tod tes, tshwj xeeb yog tsim los tso cov av khib nyiab, av, lossis cov khib nyiab uas nyob hauv qab ntawm cov kav dej, lossis tshem tawm cov seem uas tsis muaj zog. Nws feem ntau yog ntsia ntawm cov ntsiab lus qis lossis qhov kawg ntawm lub network, nrog rau txoj kab uas hla feem ntau me dua cov kav dej loj. Thaum qhib, nws siv cov dej nrawm nrawm los yaug cov impurities tawm ntawm qhov system. Nws tus qauv tsim tshwj xeeb los tiv thaiv clogging thiab hnav tsis kam; Cov kev teeb tsa muaj xws li ntsaws li qub lossis pob li qub rau kev ua haujlwm ceev thiab ua kom muaj zog scouring.

2. Installation Position & Application – Installation Locations and Use Cases

✅ Hauv qhov tseeb engineering, lub sluice valve muaj nuj nqi hauv cov dej ua haujlwm ua "kev nyab xeeb xauv" rau kev saib xyuas ntawm lub network, thaum lub tshuab nqus tsev ua lub luag haujlwm ntawm "tus huv" kom tswj tau cov dej zoo thiab tiv thaiv cov pa phem thib ob.

✅Yog hais tias lub installation txoj hauj lwm yog thim rov qab - piv txwv li, siv lub sluice valve ntawm qhov qis taw tes rau sludge paug - sediment yuav yooj yim jam lub rooj vag qhia slots, ua rau lub valve tsis kaw nruj nreem. Piv txwv li, siv lub pob valve ntawm lub hauv paus ntsiab lus tsis tuaj yeem muab kev sib khi ruaj khov.

3. Kev tsim qauv & kev ua haujlwm - Cov yam ntxwv ntawm kev ua haujlwm thiab kev ua haujlwm

✅A lub valvefeem ntau nta lub qia tsis sawv los yog nce qia tsim, nrog cov qia xov koom nrog lub rooj vag txiv ntoo; tig lub handwheel nce los yog txo lub rooj vag. Nws cov sealing nto yog hlau-rau-hlau los yog resilient-seated (xws li, EPDM), thiab tus nqi to yuav tsum tau raws li ISO 5208 Class A (zero to).

✅A scour valvefeem ntau yog hom qhib ceev (piv txwv li, 90℃-rotation pob valve lossis ntsaws valve) kom tso tawm sai sai ntawm cov dej ntws tawm. Nws cov khoom siv lub rooj zaum yog qhov hnav-tiv taus dua, thiab txoj hauv kev ntws feem ntau yog tag nrho-bore lossis txo-dhau los txo qhov chaw tuag rau cov av nkos.

✅Ib qho kev xav tsis zoo: qee tus kws tsim khoom sim siv lub qhov dej tawm los ua lub pob valve, tab sis hauv qab ntawm lub rooj vag tsim cov av nkos hauv cheeb tsam, uas ua rau ua rau lub sijhawm kaw. Qhov no yog qhov tseeb yog vim li cas qhov sib txawv ntawm lub sluice valve thiab scour valve yuav tsum tau qhia meej meej hauv phau ntawv saib xyuas - kev xaiv tsis raug ncaj qha ua rau lub rooj puas tsuaj lossis kev ua haujlwm tsis zoo.

4. Kev Qhia Txog Kev Xaiv - Cov Txheej Txheem Xaiv Qhov Tseem Ceeb

• Yog hais tias yuav tsum tau kaw-off thiab lub sij hawm ntev sealing, xaiv ib tug sluice valve ua raws li AWWA C509 los yog C515 qauv.
• Yog hais tias cov sludge tawm mus ib ntus thiab dej ntws tawm ntawm cov kav dej tuag tas yuav tsum tau xaiv, xaiv ib qho hnav-resistant scour valve (xws li, eccentric plug valve lossis tag nrho-welded pob valve).

Rau tib cov yeeb nkab seem, yog tias ob lub valve tau teeb tsa nyob ib sab, xyuas kom meej tias lub sluice valve tau muab tso rau hauv dej (raws li lub ntsiab kev rho tawm valve) thiab lub pob valve tau muab tso rau hauv qab ntawm qhov qis (raws li qhov chaw tawm). Hauv kev ua haujlwm ua ntu zus, ib txwm qhib lub pob valve ua ntej, tom qab ntawd kho me ntsis ntawm lub qhov dej ntws los tswj cov dej ntws ntws - qhov no yog cov qauv sib txuas sib txuas feem ntau pom nyob rau hauv lub npe hu ua sluice valve vs scour valve daim duab.
