Koj yuav tsum tau nruab lub valve, tab sis xaiv qhov tsis ncaj ncees lawm yuav txhais tau tias cov sij hawm ua hauj lwm ntxiv tom qab. Kev kho yooj yim tuaj yeem yuam koj txiav cov kav dej thiab kaw tag nrho cov kab ke.
Lub pob valve ob lub koomhaum tuaj yeem raug tshem tawm tag nrho los ntawm lub raj xa dej rau kev kho, thaum ib lub koomhaum tsis tuaj yeem. Qhov no ua rau ob lub koomhaum tsim qauv zoo tshaj plaws rau kev saib xyuas thiab kev pabcuam ntev.
Lub peev xwm los ua haujlwm yooj yim rau lub valve yog qhov tseem ceeb hauv tag nrho cov nqi ntawm cov tswv. Nws yog ib lub ntsiab lus tseem ceeb uas kuv tham nrog cov neeg koom tes xws li Budi, tus thawj tswj kev yuav khoom hauv Indonesia. Nws cov neeg siv khoom, tshwj xeeb tshaj yog cov chaw tsim khoom lag luam, tsis tuaj yeem them taus lub sijhawm ntev. Lawv yuav tsum muaj peev xwm sib pauv tawm lub valve cov ntsaws ruaj ruaj lossis tag nrho lub cev lub cev hauv feeb, tsis yog teev. Kev nkag siab txog qhov sib txawv ntawm kev sib txawv ntawm ib leeg thiab ob lub koom haum tsim yuav pab koj xaiv lub valve uas txuag koj lub sijhawm, nyiaj txiag, thiab mob taub hau loj hauv txoj kev.
Dab tsi yog qhov txawv ntawm ib leeg lub pob valve thiab ob lub koomhaum pob valve?
Koj pom ob lub valve uas zoo sib xws tab sis muaj lub npe sib txawv thiab tus nqi. Qhov no ua rau koj xav tsis thoob yog tias qhov kev xaiv pheej yig dua ib leeg yog "zoo txaus" rau koj qhov project.
Ib lub koom haum ob leeg muaj xov txuas ntawm ob qho kawg, tso cai rau nws tshem tawm tag nrho. Ib lub koom haum muaj ib qho txuas, txhais tau hais tias ib sab yog ruaj khov, feem ntau yog cov cement hnyav.
Xav txog nws zoo li kho lub log tsheb. Ob lub koom haum valve zoo li lub log tuav los ntawm cov txiv ntoo; koj tuaj yeem yooj yim tshem tag nrho lub log tawm los kho nws. Lub union valve ib leeg zoo li lub log uas yog welded rau lub qag ntawm ib sab; koj tsis tuaj yeem tshem nws tiag tiag rau kev pabcuam. Koj tsuas tuaj yeem txiav ib qho kawg thiab viav vias tawm ntawm txoj kev. Yog hais tias lub valve lub cev nws tus kheej tsis ua hauj lwm los yog koj yuav tsum tau hloov cov ntsaws ruaj ruaj, lubob uniontsim yog loj heev superior. Budi cov neeg cog lus tsuas yog siv ob lub koom haum li qub rau cov ntawv thov tseem ceeb vim tias lawv tuaj yeem ua tiav kev hloov pauv hauv qab tsib feeb yam tsis tau txiav ib lub yeeb nkab. Tus nqi me me ntxiv ua ntej them rau nws tus kheej thawj zaug kev saib xyuas yuav tsum tau ua.
Dab tsi yog qhov txawv ntawm ib lub valve thiab ob lub valve?
Koj hnov cov lus zoo li "ib lub valve" thiab "ob lub valve" thiab tsis meej pem. Koj txhawj xeeb tias koj tuaj yeem txhais cov ntsiab lus tsis raug rau ib qhov project, ua rau kev txiav txim tsis raug.
"Single valve" feem ntau txhais tau hais tias ib qho yooj yim, ib-daim valve uas tsis muaj kev sib koom ua ke. "Ob chav valve" feem ntau yog luv luv rau "ob lub koom haum lub pob valve," uas yog ib lub valve uas muaj ob lub koomhaum sib txuas.
Cov terminology tuaj yeem ua kom yuam kev. Cia peb qhia meej. Ib qho "ib lub valve" hauv nws daim ntawv yooj yim feem ntau yog "compact" lossisib lub pob valve. Nws yog ib qho chaw kaw uas yog glued ncaj qha rau hauv cov kav dej. Nws yog pheej yig thiab yooj yim, tab sis yog tias nws ua tsis tau, koj yuav tsum txiav nws tawm. Ib tug "ob lub valve" los yog "ob lub union valve"hais txog peb cov khoom lag luam hero: ib chav tsev peb-thooj (ob lub koom haum xaus thiab lub cev tseem ceeb) uas tso cai rau kev tshem tawm yooj yim. Nws yog ib qho tseem ceeb kom tsis txhob cuam tshuam qhov no nrog "ob chav thaiv" teeb, uas suav nrog kev siv ob qhov sib cais, tus kheej li qub rau kev sib cais siab. Rau 99% ntawm cov ntawv thov dej, ib qho "ob chav sib koom ua ke" qhov kev pabcuam zoo tshaj plaws ntawm lub pob valve. Pntek rau txhua qhov kev teeb tsa zoo.
Valve Serviceability Sib piv
| Hom Valve | Nws puas tuaj yeem raug tshem tawm tag nrho? | Yuav kho / hloov li cas? | Qhov zoo tshaj plaws siv Case |
|---|---|---|---|
| Compact (One-Piece) | No | Yuav tsum tau txiav tawm ntawm cov kav dej. | Tsawg-qis, tsis tseem ceeb daim ntawv thov. |
| Ib leeg Union | No | Nws tuaj yeem raug txiav tawm ntawm ib sab nkaus xwb. | Kev siv tau txwv tsis pub siv tau. |
| Ob chav Union | Yog lawm | Unscrew ob lub unions thiab tshem tawm. | Tag nrho cov txheej txheem tseem ceeb yuav tsum tau kho. |
Dab tsi yog qhov txawv ntawm hom 1 thiab hom 2 pob valve?
Koj tab tom saib daim phiaj xwm qub lossis tus neeg sib tw cov ntawv spec thiab saib "Hom 1" lossis "Hom 2" valve. Cov jargon uas niaj hnub no ua rau tsis meej pem thiab ua rau nws nyuaj rau kev sib piv rau cov khoom niaj hnub.
Qhov no yog cov laus terminology. "Hom 1" feem ntau yog xa mus rau ib qho yooj yim, ib-daim valve tsim.
Xav txog nws zoo li lub tsheb "Type 1" yog Model T thiab "Type 2" yog lub tsheb niaj hnub. Cov tswv yim zoo ib yam, tab sis thev naus laus zis thiab kev tsim qauv sib txawv hauv ntiaj teb. Ntau xyoo dhau los, kev lag luam tau siv cov ntsiab lus no los sib txawv cov qauv pob valve. Niaj hnub no, cov ntsiab lus feem ntau tsis siv lawm, tab sis lawv tseem tuaj yeem tshwm sim ntawm cov phiaj xwm qub. Thaum kuv pom qhov no, kuv piav qhia rau cov neeg koom tes zoo li Budi tias peb Pntektiag union pob li qubYog cov kev hloov pauv niaj hnub no ntawm "Type 2" lub tswv yim. Lawv tau tsim los ntawm hauv av kom yooj yim lub rooj zaum thiab kev hloov pauv thiab kev tshem tawm hauv kab.
Dab tsi yog qhov txawv ntawm DPE thiab SPE pob li qub?
Koj nyeem ib daim ntawv qhia txog kev qhia txog DPE lossis SPE rooj zaum. Cov ntsiab lus no tsis meej pem, thiab koj ntshai xaiv qhov tsis ncaj ncees lawm tuaj yeem tsim qhov xwm txheej txaus ntshai hauv koj lub raj xa dej.
SPE (Ib leeg Piston Effect) thiab DPE (Double Piston Effect) hais txog yuav ua li cas lub rooj zaum valve tuav lub siab thaum lub valve kaw. SPE yog tus qauv rau PVC li qub, raws li nws cia li vents siab yam xyuam xim.
Qhov no tau txais kev, tab sis lub tswv yim tseem ceeb rau kev nyab xeeb. Nyob rau hauv lub kaw valve, lub siab tuaj yeem qee zaum ua rau hauv nruab nrab lub cev kab noj hniav.
- SPE (Ib Piston Effect):Qhov no yog tus qauv kev lag luam rau cov hom phiaj dav dav PVC pob li qub. IbSPE roojseals tiv thaiv siab los ntawm sab sauv. Txawm li cas los xij, yog tias muaj kev ntxhov siabsab hauvlub valve lub cev, nws tuaj yeem ruaj ntseg thawb dhau lub rooj zaum hauv qab thiab qhov cua. Nws yog ib tug self-relieving tsim.
- DPE (Double Piston Effect): A DPE roojtuaj yeem foob tiv thaiv los ntawmob leegsab. Qhov no txhais tau tias nws tuaj yeem ntxiab siab hauv lub cev kab noj hniav, uas tuaj yeem ua rau muaj kev phom sij yog tias nws nce ntxiv vim thermal expansion. Qhov kev tsim no yog rau cov kev siv tshwj xeeb thiab yuav tsum tau muaj kev sib cais ntawm lub cev kab noj hniav.
Rau txhua daim ntawv thov dej txheem, zoo li Budi cov neeg siv khoom muaj, tus qauv SPE muaj kev nyab xeeb dua thiab peb tsim dab tsiPntek li qub. Nws tiv thaiv kev phom sij siab tsim tau.
Xaus
Lub pob valve ob lub koomhaum yog qhov zoo tshaj rau txhua qhov kev xav tau kev saib xyuas, vim nws tuaj yeem raug tshem tawm tag nrho yam tsis muaj cov kav dej. Kev nkag siab txog lub valve tsim kom ntseeg tau tias koj xaiv kom raug.
