Koj yuav tsum xaiv lub pob valve, tab sis ntau yam yog qhov nyuaj. Xaiv qhov tsis ncaj ncees lawm yuav txhais tau tias qhov tsis zoo, kev xau yav tom ntej, lossis ib qho system uas yog npau suav phem los tswj.
Plaub hom pob li qub yog categorized los ntawm lawv lub cev tsim: ib qho,ob daim, peb daim, thiab sab saum toj nkag. Txhua tus qauv tsim muaj qhov sib txawv ntawm tus nqi, lub zog, thiab kev kho yooj yim, kho kom haum rau cov kev siv tshwj xeeb thiab cov kev xav tau tu.
Kev nkag siab txog cov hom yooj yim no yog thawj kauj ruam, tab sis nws tsuas yog qhov pib xwb. Kuv feem ntau muaj kev sib tham no nrog Budi, tus thawj tswj kev yuav khoom tseem ceeb uas kuv koom nrog hauv Indonesia. Nws cov neeg muas zaub tau tsis meej pem los ntawm tag nrho cov terminology. Nws pom tias ib zaug nws tuaj yeem piav qhia qhov sib txawv ntawm qhov yooj yim, nws cov neeg siv khoom muaj kev ntseeg siab ntau dua. Lawv tuaj yeem txav los ntawm qhov tsis paub meej rau kev xaiv tus kws tshaj lij, txawm tias lawv tab tom yuav ib lub valve yooj yim rau txoj kab dej los yog ib qho nyuaj rau kev lag luam. Cia peb rhuav tshem cov hom no tiag tiag rau koj.
Dab tsi yog qhov txawv ntawm pob li qub?
Koj pom cov ntsiab lus zoo li "chaw nres nkoj puv," "trunnion," thiab "floating ball" ntawm cov ntawv tshwj xeeb. Cov lus piav qhia no ua rau nws nyuaj rau paub yog tias koj tau txais qhov kev ua tau zoo rau koj cov kev xav tau tshwj xeeb.
Tshaj li lub cev style, pob li qub yog ntaus los ntawm lawv qhov loj me (full port vs. standard port) thiab sab hauv pob tsim (floating vs. trunnion). Tag nrho qhov chaw nres nkoj ua kom tsis muaj kev txwv tsis pub khiav, thaum trunnion designs tuav tsis tshua muaj siab.
Cia peb dhia tob rau hauv ob lub cev thiab sab hauv hom. Kev tsim kho lub cev yog txhua yam txog kev nkag mus rau kev saib xyuas. Aib qhovalve yog ib chav kaw; nws pheej yig tab sis kho tsis tau. Aob daimvalve lub cev sib cais nyob rau hauv ib nrab, tso cai rau kho, tab sis koj yuav tsum tau tshem tawm ntawm lub raj xa dej ua ntej. Qhov zoo tshaj plaws tu-phooj ywg tsim yog lubpeb daimvalve. Lub hauv paus uas muaj lub pob tuaj yeem raug tshem tawm los ntawm unscrewing ob lub bolts, tawm hauv cov yeeb nkab sib txuas. Qhov no yog qhov zoo tagnrho rau cov kab uas xav tau kev pabcuam nquag. Sab hauv, "chaw nres nkoj" lossis qhov hauv lub pob tseem ceeb. Achaw nres nkoj puvvalve muaj ib lub qhov loj tib yam li cov yeeb nkab, tsim kev txwv tsis pub khiav. Astandard chaw nres nkojyog me ntsis me me, uas yog qhov zoo rau ntau daim ntawv thov. Thaum kawg, yuav luag tag nrho PVC pob li qub siv antab pobtsim, qhov system siab thawb lub pob ruaj ntseg tiv thaiv lub rooj zaum hauv qab los tsim lub foob.

Dab tsi yog qhov sib txawv ntawm pob valve txuas?
Koj tau pom lub zoo meej valve, tab sis tam sim no koj yuav tsum txuas nws. Xaiv txoj kev sib txuas tsis raug tuaj yeem ua rau muaj kev txhim kho tsis zoo, tsis tu ncua, lossis lub kaw lus koj tsis tuaj yeem ua haujlwm yam tsis muaj hacksaw.
Cov hom kev sib txuas ntau tshaj plaws rau cov pob li qub yog cov kuab tshuaj-weld sockets rau PVC daim ntawv cog lus ruaj khov, threaded xaus rau kev koom nrog cov ntaub ntawv sib txawv, flanged kawg rau cov kav dej loj, thiab kev sib koom ua ke tiag tiag rau kev pabcuam siab tshaj plaws.
Hom kev sib txuas uas koj xaiv txhais tau li cas lub valve txuas nrog koj cov kav dej.Qhov (socket).los yog "slip" kev sib txuas yog siv rau PVC yeeb nkab, tsim kom muaj kev ruaj ntseg, xau-pov thawj daim ntawv cog lus siv cov cement hnyav. Qhov no yog qhov yooj yim thiab txhim khu kev qha heev.XovCov kev sib txuas (NPT lossis BSPT) tso cai rau koj los kho lub valve rau hauv cov yeeb nkab threaded, uas yog qhov zoo rau kev txuas PVC rau cov khoom siv hlau, tab sis nws yuav tsum tau xov xov sealant thiab ceev faj installation kom tsis txhob xau. Rau cov kav dej loj (feem ntau tshaj 2 ntiv tes),flangedkev sib txuas yog siv. Lawv siv bolts thiab gasket los tsim kom muaj zog, ruaj ntseg, thiab tshem tau yooj yim. Tab sis rau qhov kawg kev ruaj ntseg hauv cov kav dej me, tsis muaj dab tsi ntaus ibMuaj tseeb Unionvalve. Qhov kev tsim no muaj ob lub union txiv ntseej uas cia koj tshem tawm tag nrho lub valve lub hauv paus lub cev rau kev kho lossis hloov thaum qhov kev sib txuas xaus tseem txuas nrog cov yeeb nkab. Nws yog qhov zoo tshaj plaws ntawm ob lub ntiaj teb: kev sib txuas ruaj khov thiab kev pabcuam yooj yim.
Sib piv hom kev sib txuas
| Hom kev sib txuas | Nws ua haujlwm li cas | Qhov zoo tshaj plaws siv rau |
|---|---|---|
| Qhov (socket) | Glued rau ntawm PVC yeeb nkab. | Permanent, leak-proof PVC systems. |
| Xov | Screws mus rau ib tug threaded yeeb nkab. | Koom nrog cov khoom sib txawv; disassembly. |
| Flanged | Bolted ntawm ob lub yeeb nkab flanges. | Cov kav dej loj loj; industrial siv. |
| Muaj tseeb Union | Unscrews tshem tawm lub cev valve. | Cov tshuab yuav tsum tau yooj yim, ceev tu. |
Qhov txawv ntawm MOV li qub yog dab tsi?
Koj xav kom automate koj lub cev, tab sis "MOV" suab zoo li cov cuab yeej ua haujlwm nyuaj. Koj tsis paub meej txog lub hwj chim, kev xaiv tswj, thiab yog tias nws tseem siv tau rau koj qhov project.
MOV stands rauMotorized Ua Haujlwm Valve, uas yog ib qho valve tswj los ntawm tus actuator. Ob hom tseem ceeb yog hluav taws xob actuators, uas siv lub tshuab hluav taws xob, thiab pneumatic actuators, uas siv cov cua compressed los khiav lub valve.
Ib qho MOV tsis yog hom tshwj xeeb ntawm lub valve; Nws yog tus qauv valve nrog lub actuator mounted rau nws. Hom actuator yog qhov tseem ceeb.Hluav taws xob actuatorsyog cov khoom siv ntau tshaj plaws rau PVC pob li qub hauv cov tshuab dej. Lawv siv lub tshuab me me los tig lub valve qhib lossis kaw thiab muaj nyob rau hauv ntau qhov hluav taws xob (xws li 24V DC lossis 220V AC) kom phim koj lub zog. Lawv zoo meej rau cov ntawv thov xws li automated irrigation zones, water treatment dosing, or remote tank filling.Pneumatic actuatorssiv lub zog ntawm compressed cua kom snap lub valve qhib lossis kaw sai heev. Lawv muaj zog heev thiab txhim khu kev qha tab sis yuav tsum muaj cua compressor thiab cov kab cua ua haujlwm. Koj feem ntau tsuas pom lawv hauv cov nroj tsuag loj loj uas cov cua compressed twb yog ib feem ntawm cov infrastructure. Rau feem ntau ntawm Budi cov neeg muas zaub, hluav taws xob actuators muab qhov zoo tshaj plaws tshuav nyiaj li cas ntawm kev tswj, nqi, thiab kev yooj yim.
Dab tsi yog qhov txawv ntawm hom 1 thiab hom 2 pob valve?
Koj tab tom nyeem ib daim ntawv qhia tshwj xeeb thiab pom "Hom 21 Pob Valve" thiab tsis muaj qhov qhia tau tias txhais tau li cas. Koj txhawj xeeb koj yuav tsis pom cov ntsiab lus tseem ceeb ntawm nws txoj kev nyab xeeb lossis kev ua haujlwm.
Cov ntsiab lus no feem ntau yog hais txog ntau tiam neeg ntawm lub koomhaum tiag tiag pob li qub los ntawm cov npe tshwj xeeb. "Hom 21" tau dhau los ua luv luv rau kev tsim qauv niaj hnub, kev ua haujlwm siab uas suav nrog qhov tseem ceeb ntawm kev nyab xeeb thiab kev siv tau zoo li cov txiv ntoo thaiv kev nyab xeeb.
