Koj pom "union valve" thiab "ball valve" teev nyob rau hauv daim ntawv teev npe, tab sis lawv puas txawv? Kev xaiv tsis raug txhais tau tias koj yuav tsum txiav tawm lub valve zoo meej tom qab tsuas yog los kho lub twj tso kua mis.
Lub pob valve piav qhia txog lub tshuab kaw (lub pob). Lub union piav qhia txog hom kev sib txuas uas tso cai rau kev tshem tawm (union nuts). Lawv tsis yog sib cais; lub valve uas siv tau ntau yam tshaj plaws yog alub pob valve sib koom ua ke tiag tiag, uas muab ob qho tib si nta ua ke.
Qhov no yog ib qho ntawm cov ntsiab lus tsis meej pem uas kuv pom ntau tshaj plaws, thiab nws yog qhov sib txawv tseem ceeb rau txhua tus kws tshaj lij. Kuv feem ntau tham txog qhov no nrog kuv tus khub Budi hauv Indonesia, vim nws cov neeg siv khoom xav tau cov kev daws teeb meem uas tsis yog tsuas yog ua tau zoo xwb tab sis kuj ua tau zoo kom tswj tau mus ntev. Qhov tseeb yog, cov lus no piav qhia txog ob yam sib txawv: ib qho qhia kojli caslub valve ua haujlwm, thiab lwm tus qhia kojnws txuas li casrau cov yeeb nkab. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev tsim ib lub kaw lus ntse thiab siv tau.
Qhov txawv ntawm lub pob valve thiab lub union pob valve yog dab tsi?
Koj tau teeb tsa lub pob valve ib txwm muaj, nplaum nws mus tas li rau hauv kab. Ib xyoos tom qab, lub foob tsis ua haujlwm, thiab koj paub tias koj tsuas yog xaiv tau txiav tag nrho lub valve thiab pib dua.
Lub pob valve txheem yog ib qho chaw uas tau teeb tsa tas mus li. Lub pob valve sib koom ua ke tiag tiag muaj cov txiv ntoo uas cia koj tshem lub cev valve nruab nrab yam tsis txiav cov yeeb nkab, ua rau kev saib xyuas lossis hloov pauv yooj yim.
Qhov no yog qhov sib txawv tseem ceeb tshaj plaws rau kev npaj mus sij hawm ntev. Xav txog nws hauv cov nqe lus ntawm "mus tas li" piv rau "kev pabcuam tau." Lub pob valve me me, tus qauv yog solvent-welded ncaj qha rau hauv cov kav dej. Thaum nws nyob hauv, nws nyob rau hauv zoo. Qhov no zoo rau cov kab yooj yim, tsis tseem ceeb. Alub pob valve sib koom ua ke tiag tiag, txawm li cas los xij, yog tsim los rau yav tom ntej. Koj siv cov tshuaj yaj los vuam ob lub tailpieces sib cais rau ntawm lub yeeb nkab, thiab lub cev valve tseem ceeb nyob nruab nrab ntawm lawv. Nws tau tuav los ntawm ob lub txiv ntoo loj union. Yog tias koj xav tau hloov lub valve lub foob lossis tag nrho lub cev, koj tsuas yog tshem cov txiv ntoo thiab tsa nws tawm. Qhov no yog vim li cas peb ntawm Pntek txhawb nqa qhov kev tsim union tiag tiag; nws hloov kev kho loj mus ua haujlwm yooj yim 5 feeb.
Tus Qauv vs. Qhov Tseeb Union Pob Valve
| Feature | Txheem (Compact) Pob Valve | Muaj tseeb Union Pob Valve |
|---|---|---|
| Kev teeb tsa | Ruaj khov (solvent-welded) | Siv tau (cov txiv ntoo sib koom ua ke) |
| Kev Txij Nkawm | Yuav tsum tau txiav cov yeeb nkab | Lub cev tshem tawm kom yooj yim kho |
| Tus nqi pib | Qis dua | Siab dua |
| Tus Nqi Mus Ntev | Qis dua (kho kim heev) | Siab dua (txuag lub sijhawm thiab kev ua haujlwm) |
Lub union valve yog dab tsi?
Koj pom lo lus "union valve" thiab xav tias nws yog ib pawg sib txawv kiag li, zoo li lub qhov rooj valve lossis lub qhov kuaj valve. Qhov kev ua siab deb no tuaj yeem ua rau koj tsis xaiv qhov kev xaiv zoo tshaj plaws.
Lub valve sib koom ua ke tsis yog ib hom mechanism, tab sis yog ib hom kev sib txuas. Nws yog txhua lub valve uas siv cov khoom sib koom ua ke (cov txiv ntoo threaded) los txuas lub cev valve rau cov yeeb nkab kawg, ua rau yooj yim tshem tawm.
Lub "kev sib koom ua ke" nws tus kheej yog ib daim duab zoo kawg nkaus ntawm kev tsim kho. Nws muaj peb qhov tseem ceeb: ob lub tailpieces uas txuas rau lub yeeb nkab (los ntawm kev sib txuas ntawm cov kuab tshuaj lossis cov xov), thiab lub txiv ntoo uas rub lawv ua ke los tsim ib lub foob. Ib "lub valve sib koom ua ke"tsuas yog tsim cov yam ntxwv no rau hauv lub valve tsim. Yog li, koj tuaj yeem muaj lub pob valve sib koom ua ke tiag tiag, lub valve kuaj xyuas sib koom ua ke tiag tiag, lossis lub valve diaphragm sib koom ua ke tiag tiag. Lub hom phiaj yeej ib txwm zoo ib yam:kev pabcuam tau zooNws tso cai rau koj cais thiab tshem tawm ib daim khoom siv yam tsis tas yuav txo qhov siab ntawm tag nrho lub kaw lus lossis, qhov tseem ceeb dua, yam tsis tas txiav koj cov yeeb nkab. Txoj hauv kev modular no yog lub hauv paus ntawm kev tsim cov kav dej niaj hnub, ua haujlwm tau zoo thiab yog ib feem tseem ceeb ntawm lub tswv yim "yeej-yeej" uas kuv qhia rau cov neeg koom tes zoo li Budi. Nws txuag nws cov neeg siv khoom lub sijhawm thiab nyiaj txiag thoob plaws lub neej ntawm lub kaw lus.
Peb hom li qub yog dab tsi?
Koj tau siv lub pob valve rau txhua yam, tab sis ib qho kev siv yuav tsum tau tswj qhov ntws kom meej. Koj sim kaw ib feem ntawm lub pob valve, tab sis nws nyuaj rau tswj thiab koj hnov lub suab txawv txawv.
Peb hom valve tseem ceeb uas siv tau yog Kaw-Off (On/Off), Throttling (Regulating), thiab Non-Return (Backflow Prevention). Txhua hom valve no yog tsim los rau ib txoj haujlwm sib txawv kiag li, thiab yog siv tsis raug ces yuav ua rau koj lub system puas tsuaj.
Kev paub txog cov pawg yooj yim yog qhov tseem ceeb rau kev xaiv cov cuab yeej zoo rau txoj haujlwm. Kev siv lub valve tsis raug yog qhov yuam kev ntau heev. Lub pob valve yog ib qholub valve kaw; nws tau tsim los kom qhib tag nrho lossis kaw tag nrho. Siv nws los tswj cov dej ntws tuaj yeem ua rau muaj kev kub ntxhov uas ua rau lub pob thiab lub rooj zaum puas tsuaj, ua rau nws tsis ua haujlwm.
Cov Qeb ntawm Valve Piav Qhia
| Hom Valve | Kev Ua Haujlwm Tseem Ceeb | Piv txwv li niaj zaus | Cov Ntaub Ntawv Siv Zoo Tshaj Plaws |
|---|---|---|---|
| Kaw-Tawm (Rau/Tawm) | Yuav tsum nres lossis tso cai rau dej ntws tag nrho. | Pob Valve, Rooj Vag Valve, Npauj Npaim Valve | Cov seem lossis cov khoom siv cais tawm. |
| Kev tswj hwm (Throttling) | Txhawm rau tswj qhov ceev lossis qhov siab ntawm kev ntws. | Lub Ntiaj Teb Valve, Koob Valve | Teem ib qho nqi ntws kom meej. |
| Kev tsis rov qab los (Backflow) | Yuav kom tso cai rau kev ntws mus rau hauv ib qho kev taw qhia xwb. | Kos Valve, Ko Taw Valve | Tiv thaiv lub twj tso kua mis los ntawm kev ntws rov qab. |
4 hom pob valve yog dab tsi?
Koj paub txog cov li qub sib koom ua ke tiag tiag, tab sis koj pom lwm cov kev xaiv xws li "compact" lossis "one-piece." Koj tsis paub tseeb tias qhov twg zoo tshaj plaws rau ntau daim ntawv thov, thiab koj yuav them nyiaj ntau dhau rau cov yam ntxwv uas koj tsis xav tau.
Plaub hom pob valve tseem ceeb yog sib txawv los ntawm kev tsim lub cev: Ib-Daim (kaw), Ob-Daim (xov lub cev), Peb-Daim (zoo li lub koom haum tiag tiag), thiab Compact (tus qauv yooj yim, pheej yig, feem ntau yog ib daim).
Txawm hais tias lub tshuab sab hauv zoo ib yam (lub pob uas tig tau), txoj kev uas lub cev raug tsim los txiav txim siab nws tus nqi thiab kev pabcuam. Hauv ntiaj teb ntawm PVC, peb feem ntau tsom mus rau ib daim/me me thiab peb daim/kev sib koom ua ke tiag tiag.
- Ib Daim /Lub Pob Valve Me Me:Lub cev valve yog ib lub kaw lus kaw. Qhov no yog qhov tsim pheej yig tshaj plaws. Nws tsis hnyav, yooj yim, thiab zoo meej rau cov ntawv thov uas tsis muaj kev txhawj xeeb txog kev saib xyuas thiab tus nqi yog qhov tseem ceeb.
- Ob-Daim Pob Valve:Lub cev yog ua los ntawm ob daim uas ntsia hlau ua ke, ntes lub pob thiab kaw sab hauv. Qhov no tso cai rau qee qhov kho tab sis feem ntau yuav tsum tau tshem nws tawm ntawm kab. Nws feem ntau tshwm sim hauv cov hlau valves.
- Peb Daim (Muaj Tseeb Union) Lub Pob Valve:Qhov no yog tus qauv tsim zoo tshaj plaws. Nws muaj ob lub qhov txuas kawg (cov khoom seem) thiab lub cev nruab nrab. Qhov no tso cai rau lub cev tseem ceeb kom raug tshem tawm rau kev kho lossis hloov pauv yam tsis cuam tshuam lub yeeb nkab. Qhov no yog qhov kev xaiv txhim khu kev qha thiab pheej yig tshaj plaws rau cov ntawv thov tseem ceeb rau lub sijhawm ntev.
Ntawm Pntek, peb tsom mus rau kev muab cov khoom me me zoo tshaj plaws thiabqhov tseeb union valves, muab rau peb cov neeg koom tes zoo li Budi cov kev xaiv zoo rau txhua yam kev xav tau ntawm cov neeg siv khoom.
Xaus lus
Lub pob valve yog ib lub tshuab; lub union yog ib qho kev sib txuas. Lub pob valve union tiag tiag muab lawv ua ke, muab kev tswj hwm zoo tshaj plaws thiab yooj yim txij nkawm rau txhua lub tshuab plumbing.
