Koj pom "union valve" thiab "pob valve" teev, tab sis lawv txawv? Xaiv qhov tsis ncaj ncees lawm txhais tau tias koj yuav tau txiav tawm lub valve zoo kawg nkaus tom qab tsuas yog ua haujlwm rau lub twj tso kua mis.
Lub pob valve piav qhia txog lub tshuab kaw (ib lub pob). Lub union piav txog hom kev sib txuas uas tso cai rau tshem tawm (union txiv ntoo). Lawv tsis yog kev sib koom ua ke; qhov ntau yam valve yog atiag union pob valve, uas muab ob qho tib si nta.
Qhov no yog ib qho ntawm feem ntau cov ntsiab lus ntawm kev tsis meej pem kuv pom, thiab nws yog ib qho kev sib txawv tseem ceeb rau txhua tus kws tshaj lij. Kuv feem ntau sib tham txog qhov no nrog kuv tus khub Budi hauv Indonesia, vim tias nws cov neeg siv khoom xav tau cov kev daws teeb meem uas tsis yog siv tau zoo xwb tab sis kuj muaj txiaj ntsig zoo los tuav lub sijhawm ntev. Qhov tseeb yog, cov ntsiab lus no piav txog ob yam sib txawv: ib qho qhia rau kojua li caslub valve ua haujlwm, thiab lwm yam qhia rau kojnws txuas li casmus cev. Nkag siab qhov sib txawv no yog qhov tseem ceeb rau kev tsim kom muaj lub ntsej muag ntse, kev pabcuam.
Dab tsi yog qhov txawv ntawm lub pob valve thiab lub union pob valve?
Koj tau nruab ib lub pob valve, mus tas li gluing rau hauv kab. Ib xyoos tom qab, lub foob tsis ua haujlwm, thiab koj paub tias koj txoj kev xaiv tsuas yog txiav tawm tag nrho lub valve thiab pib dua.
Lub pob valve txheem yog ib qho, ib qho chaw ruaj khov. Lub koom haum pob valve muaj tseeb threaded txiv ntseej uas cia koj tshem tawm lub hauv paus valve lub cev yam tsis tau txiav cov yeeb nkab, ua kev tu lossis hloov yooj yim.
Qhov no yog qhov sib txawv tseem ceeb tshaj plaws rau kev npaj mus sij hawm ntev. Xav txog nws nyob rau hauv cov nqe lus ntawm "ntev" piv rau "serviceable." Tus qauv, compact pob valve yog hnyav-welded ncaj qha rau hauv cov kav dej. Thaum nws nyob rau hauv, nws yog nyob rau hauv zoo. Qhov no yog qhov zoo rau cov kab yooj yim, tsis tseem ceeb. Atiag union pob valveTxawm li cas los xij, yog tsim los rau yav tom ntej. Koj hnyav-weld ob cais tailpieces rau cov yeeb nkab, thiab lub ntsiab valve lub cev zaum ntawm lawv. Nws yog nyob rau hauv qhov chaw los ntawm ob loj union txiv ntseej. Yog tias koj xav tau hloov lub valve cov ntsaws ruaj ruaj lossis tag nrho lub cev, koj tsuas yog unscrew cov txiv ntseej thiab nqa nws tawm. Qhov no yog vim li cas peb ntawm Pntek champion qhov tseeb union tsim; nws hloov kho loj rau hauv txoj haujlwm yooj yim 5-feeb.
Standard vs True Union Pob Valve
| Feature | Standard (Compact) Pob Valve | Muaj tseeb Union Pob Valve |
|---|---|---|
| Kev teeb tsa | Permanent (hloov-welded) | Serviceable (union ceev) |
| Kev tu | Yuav tsum tau txiav cov yeeb nkab | Lub cev tshem tawm kom kho tau yooj yim |
| Tus nqi pib | qis | Siab dua |
| Lub Sijhawm Ntev | Tsawg dua (khoom kho dua) | Siab dua (txuag lub sijhawm & kev ua haujlwm) |
Lub union valve yog dab tsi?
Koj pom lub sij hawm "union valve" thiab xav tias nws yog ib pawg sib txawv kiag li, zoo li lub rooj vag valve lossis daim tshev valve. Qhov kev tsis txaus siab no tuaj yeem ua rau koj xaiv qhov kev xaiv ua tau zoo tshaj plaws.
Lub union valve tsis yog ib hom kev sib txuas, tab sis yog hom kev sib txuas. Nws yog txhua lub valve uas siv lub koom haum fittings (threaded txiv ntseej) los txuas lub valve lub cev rau cov yeeb nkab kawg, tso cai rau kev tshem tawm yooj yim.
Lub "union" nws tus kheej yog ib qho zoo ntawm engineering. Nws muaj peb qhov tseem ceeb: ob lub tailpieces uas txuas rau cov yeeb nkab (txawm yog los ntawm hnyav weld lossis threads), thiab cov txiv ntoo threaded uas rub lawv ua ke los tsim ib lub foob. A "union valve"Tsuas yog tsim cov yam ntxwv no rau hauv lub valve tsim. Yog li, koj tuaj yeem muaj lub koomhaum tiag tiag pob valve, lub koomhaum pabcuam tiag tiag, lossis lub koomhaum tiag tiag diaphragm valve. Lub hom phiaj yeej ib txwm zoo ib yam:kev pabcuam. Nws tso cai rau koj cais tawm thiab tshem tawm ib qho khoom siv yam tsis muaj kev ntxhov siab rau tag nrho lub cev lossis, qhov tseem ceeb tshaj, tsis txhob txiav koj cov yeeb nkab. Qhov kev hloov pauv no yog lub hauv paus ntawm kev tsim cov kav dej niaj hnub, muaj txiaj ntsig zoo thiab qhov tseem ceeb ntawm "yeej-yeej" lub tswv yim uas kuv qhia nrog cov neeg koom tes xws li Budi. Nws txuag nws cov neeg siv khoom lub sijhawm thiab nyiaj txiag thoob plaws lub neej ntawm qhov system.
Peb hom li qub yog dab tsi?
Koj tau siv pob li qub rau txhua yam, tab sis ib daim ntawv thov yuav tsum muaj kev tswj xyuas kom meej. Koj sim kaw ib nrab ntawm lub pob valve, tab sis nws nyuaj rau tswj thiab koj hnov ib lub suab txawv txawv.
Peb hom kev ua haujlwm tseem ceeb ntawm li qub yog kaw-Off (On/Off), Throttling (Regulating), thiab Tsis Rov Qab (Kev Tiv Thaiv Backflow). Txhua hom yog tsim los rau txoj haujlwm sib txawv kiag li, thiab siv qhov tsis ncaj ncees lawm tuaj yeem ua rau koj lub cev puas tsuaj.
Paub txog cov pawg hauv paus yog qhov tseem ceeb rau kev xaiv cov cuab yeej zoo rau txoj haujlwm. Kev siv lub valve tsis raug yog ib qho yuam kev heev. Lub pob valve yog ibkaw-off valve; nws yog tsim los kom qhib tag nrho lossis kaw tag nrho. Kev siv nws los ua kom lub zog ntws tuaj yeem ua rau muaj kev kub ntxhov uas ua rau lub pob thiab lub rooj zaum, ua rau nws tsis ua haujlwm.
Valve Categories piav qhia
| Hom Valve | Lub luag haujlwm tseem ceeb | Piv txwv | Qhov zoo tshaj plaws siv Case |
|---|---|---|---|
| Shut-Off (On/Off) | Txhawm rau nres lossis tso cai ntws. | Pob Valve, Rooj vag Valve, Npauj Npaim Valve | Kev cais cov ntu lossis cov khoom siv. |
| Throttling (Regulating) | Txhawm rau tswj qhov nrawm lossis siab ntws. | Globe Valve, Koob Valve | Teem ib tug meej txaus tus nqi. |
| Tsis Rov Qab (Backflow) | Kom tso cai rau ntws hauv ib qho kev taw qhia xwb. | Kos Valve, Ko Taw Valve | Tiv thaiv lub twj tso kua mis los ntawm backflow. |
Dab tsi yog 4 hom pob li qub?
Koj paub txog lub koomhaum tiag tiag, tab sis koj pom lwm yam kev xaiv xws li "compact" lossis "ib thooj." Koj tsis paub meej tias qhov twg yog qhov zoo tshaj plaws rau cov ntawv thov sib txawv, thiab tej zaum koj yuav tau them nyiaj ntau dua rau cov yam ntxwv uas koj tsis xav tau.
Plaub yam tseem ceeb ntawm lub pob li qub yog qhov txawv ntawm lub cev kev tsim kho: Ib-Piece (sau), Ob-Piece (threaded lub cev), Peb-Piece (zoo li lub koomhaum tiag), thiab Compact (ib qho yooj yim, kev lag luam tsim, feem ntau ib-daim).
Thaum lub hauv paus mechanism yog tib yam (ib lub pob rotating), txoj kev lub cev yog tsim dictates nws cov nqi thiab serviceability. Nyob rau hauv lub ntiaj teb no ntawm PVC, peb feem ntau tsom rau ib-thooj / compact thiab peb-thooj / tiag union tsim.
- Ib Daim /Compact Pob Valve:Lub valve lub cev yog ib qho, kaw chav tsev. Qhov no yog qhov kev siv nyiaj txiag tshaj plaws. Nws yog lub teeb yuag, yooj yim, thiab zoo meej rau cov ntawv thov uas kev saib xyuas tsis muaj kev txhawj xeeb thiab tus nqi yog thawj tus tsav tsheb.
- Ob-Piece Pob Valve:Lub cev yog ua los ntawm ob daim uas ntsia hlau ua ke, cuab lub pob thiab ntsaws rau hauv. Qhov no tso cai rau qee qhov kev kho tab sis feem ntau yuav tsum tau tshem tawm ntawm txoj kab. Nws muaj ntau dua hauv cov hlau li qub.
- Peb daim (True Union) Pob Valve:Qhov no yog tus qauv tsim. Nws muaj ob qhov kawg txuas (tailpieces) thiab lub cev nruab nrab. Qhov no tso cai rau lub cev tseem ceeb raug tshem tawm los kho lossis hloov yam tsis muaj kev cuam tshuam cov yeeb nkab. Qhov no yog qhov kev xaiv zoo tshaj plaws thiab muaj txiaj ntsig zoo rau cov ntawv thov tseem ceeb hauv lub sijhawm ntev.
Ntawm Pntek, peb tsom mus rau kev muab qhov zoo tshaj plaws compact thiabtiag union li qub, muab peb cov neeg koom tes zoo li Budi txoj kev xaiv rau txhua tus neeg siv khoom xav tau.
Xaus
Lub pob valve yog lub tshuab; lub union yog kev sib txuas. Lub koom haum muaj tseeb pob valve ua ke nrog lawv, muab kev tswj hwm zoo tshaj plaws thiab kev saib xyuas yooj yim rau txhua qhov kev tshaj lij kav dej.
