Koj yuav tsum tswj cov dej ntws, tab sis saib ntau ntau hom valve. Xaiv qhov tsis ncaj ncees lawm tuaj yeem ua rau xau, thaiv, lossis tsis tswj koj lub cev kom raug, ua rau muaj kev puas tsuaj ntau.
Muaj ntau hom PVC li qub, tab sis feem ntau yogpob li qubrau on/off tswj,check li qubtiv thaiv backflow, thiabrooj vag li qubrau kev sib cais yooj yim. Txhua hom ua haujlwm sib txawv heev hauv lub tshuab dej.
Nkag siab txog cov haujlwm tseem ceeb ntawm txhua lub valve yog qhov tseem ceeb. Kuv feem ntau siv qhov piv txwv yooj yim thaum tham nrog cov neeg koom tes xws li Budi hauv Indonesia. Lub pob valve zoo li lub teeb hloov-nws yog nyob rau lossis tawm, nrawm. Lub rooj vag valve zoo li qhov qeeb qeeb, txhob txwm tshaj tawm. Thiab daim tshev valve zoo li lub qhov rooj ib-txoj kev uas tsuas yog cia kev khiav mus los ntawm ib qho kev taw qhia xwb. Nws cov neeg siv khoom - cov neeg cog lus, cov neeg ua liaj ua teb, cov chaw tsim khoom hauv pas dej - pom qhov no ua rau nws yooj yim dua los xaiv cov khoom tsim nyog. Thaum koj paub tias txoj haujlwm twg lub valve yuav tsum ua, qhov kev xaiv yuav pom tseeb.
Puas yog tag nrho PVC li qub?
Koj pom ob lub pob PVC uas zoo ib yam, tab sis ib qho nqi ob zaug ntau dua. Nws yog kev ntxias kom yuav tus pheej yig dua, tab sis koj txhawj xeeb nws yuav ua tsis tiav thiab ua rau muaj kev puas tsuaj.
Tsis yog, txhua qhov PVC li qub tsis zoo ib yam. Lawv sib txawv loj hauv cov khoom zoo, cov ntaub ntawv foob, tsim, thiab raug precision. Cov kev sib txawv no cuam tshuam ncaj qha rau ntev npaum li cas lub valve kav ntev npaum li cas thiab qhov kev ntseeg siab npaum li cas nws ua tau raws li qhov siab.
Qhov sib txawv ntawm lub valve zoo thiab qhov tsis zoo yog nyob rau hauv cov ntsiab lus koj tsis tuaj yeem pom ib txwm. Thawj yog qhovCov khoom siv PVCnws tus kheej. Peb ntawm Pntek siv 100% nkauj xwb PVC, uas yog muaj zog, ruaj, thiab muaj ib tug siab gloss tiav. Cov khoom pheej yig dua feem ntau siv cov khoom siv rov ua dua PVC nrog cov khoom ntim zoo licalcium carbonate. Qhov no ua rau lub valve hnyav dua, tab sis kuj muaj ntau nkig thiab nquag tawg. Tom ntej no yog covcov ntsaws ruaj ruaj. Cov nplhaib dawb nyob rau hauv uas kaw lub pob yog hu ua rooj. Qhov zoo li qub siv cov ntshiabPTFE (Teflon)rau ib tug du, tsis muaj kev sib txhuam, ntev-ntev sealing. Cov pheej yig dua siv cov yas qis dua uas hnav sai sai. Cov O-rings dub ntawm lub qia yuav tsum yog EPDM, uas yog zoo heev rau dej thiab UV tiv thaiv, tsis pheej yig dua NBR roj hmab. Thaum kawg, nws los rauprecision. Peb qhov kev tsim khoom siv hluav taws xob ua kom txhua lub valve tig du. Cov khoom siv tsis zoo tuaj yeem ua kom tawv thiab nyuaj tig, los yog xoob lawv xav tias tsis ntseeg.
Qhov twg zoo dua, PVC lossis hlau valve?
Hlau xav tias hnyav thiab muaj zog, thaum PVC xav tias lub teeb. Koj txoj kev xav hais tias hlau yog ib qho kev xaiv zoo dua, tab sis qhov kev xav ntawd tuaj yeem ua rau lub cev tsis zoo los ntawm corrosion.
Tsis yog zoo dua; lawv tau tsim rau ntau txoj haujlwm. PVC yog qhov zoo tshaj rau cov dej txias thiab corrosive ib puag ncig uas hlau yuav xeb lossis txeeb. Hlau yog tsim nyog rau qhov kub thiab txias, kev kub siab, thiab qee yam tshuaj.
Kev xaiv ntawm PVC thiab hlau tsis yog hais txog lub zog, nws yog hais txog chemistry. Qhov zoo tshaj plaws ntawm PVC yog tias nws yogtiv thaiv xeb thiab corrosion. Budi muaj ib tus neeg siv khoom hauv kev lag luam aquaculture uas tau siv los hloov nws cov tooj dag li qub txhua xyoo vim tias cov dej ntsev ua rau lawv txeeb tau. Txij li thaum hloov mus rau peb PVC li qub, nws tau muaj teeb meem xoom rau tsib xyoos. Lawv ua haujlwm zoo li ib hnub. Qhov no yog qhov PVC yog qhov tseeb yeej: cov dej nrog cov chiv, cov pas dej da dej, cov kab dej ntsev, thiab cov kav dej dav dav. Txawm li cas los xij, PVC muaj nws qhov txwv. Nws tsis tuaj yeem siv rau cov dej kub, vim nws yuav muag thiab ua tsis tiav. Nws kuj muaj qhov ntsuas qis dua li cov hlau. Lub valve hlau (xws li hlau lossis tooj dag) yog qhov kev xaiv nkaus xwb rau cov kav dej, cov dej kub, lossis cov ntawv thov kev lag luam siab heev. Qhov tseem ceeb yog kom phim cov khoom siv valve rau cov kua uas ntws los ntawm nws.
PVC vs. Hlau: Yam twg los xaiv?
| Feature | PVC Valve | Hlau Valve (Brass / Hlau) |
|---|---|---|
| Corrosion Resistance | Zoo heev | Poor to Good (nyob ntawm cov hlau) |
| Kub txwv | Tsawg (kwv yees 60 ° C / 140 ° F) | Siab heev |
| Siab txwv | Zoo (piv txwv li, PN16) | Zoo heev |
| Zoo tshaj rau | Dej txias, pas dej, dej | Kub Dej, Chav Dej, Siab Siab |
| Nqi | qis | Siab dua |
Dab tsi ua rau 'zoo' PVC valve?
Koj tab tom yuav khoom hauv online thiab nrhiav PVC valve rau tus nqi qis heev. Koj xav tias nws yog kev yuav khoom ntse lossis yog tias koj tab tom yuav qhov teeb meem yav tom ntej uas yuav xau thaum 2 AM.
Lub "zoo" PVC valve yog tsim los ntawm 100% nkauj xwb PVC, siv high-qib PTFE rooj zaum thiab EPDM O-rings, lem smoothly, thiab tau raug soj ntsuam los ntawm lub Hoobkas los lav nws yog tsis xau.
Muaj ob peb yam uas kuv qhia Budi pab neeg nrhiav. Ua ntej, tshuaj xyuas lublub cev. Nws yuav tsum muaj ib tug du, me ntsis glossy tag. Ib tug npub, chalky tsos feem ntau qhia txog kev siv cov fillers, uas ua rau nws nkig. Thib ob,ua haujlwm tuav. Nws yuav tsum tig nrog ib tug du, zoo ib yam kuj los ntawm tag nrho qhib mus rau tag nrho kaw. Yog hais tias nws yog nruj heev, jerky, los yog xav tias gritty, lub puab molding yog tsis zoo. Qhov no ua rau cov xau thiab tus kov uas tuaj yeem snap tawm. Thib peb, nrhiavcov cim meej. Lub valve zoo yuav raug cim kom meej nrog nws qhov loj me, qhov ntsuas siab (xws li PN10 lossis PN16), thiab cov khoom siv (PVC-U). Reputable manufacturers txaus siab rau lawv specs. Thaum kawg, nws los tso siab rau. Ntawm Pntek, txhua lub valve peb tsim yog ntsuas siab ua ntej nws tawm hauv lub Hoobkas. Qhov no guarantees nws yuav tsis xau. Qhov ntawd yog qhov tsis pom qhov koj them rau: kev thaj yeeb ntawm lub siab uas nws yuav ua haujlwm yooj yim.
Puas yog PVC valve tshiab ua qhov txawv?
Koj muaj lub qub valve uas tawv tig los yog muaj qhov qis heev. Nws zoo li qhov teeb meem me me, tab sis tsis quav ntsej nws tuaj yeem ua rau koj lub cev muaj kev cuam tshuam rau cov teeb meem loj dua.
Yog lawm, PVC valve tshiab ua rau muaj qhov sib txawv loj. Nws tam sim ntawd txhim kho kev nyab xeeb los ntawm kev hloov cov khoom nkig, ua kom muaj lub foob zoo meej kom tsis txhob xau, thiab muab kev ua haujlwm du, txhim khu kev qha thaum koj xav tau tshaj plaws.
Hloov lub qub valve tsis yog kho xwb; nws yog ib qho kev txhim kho loj hauv peb qhov tseem ceeb. Thawj yogkev nyab xeeb. PVC valve uas tau nyob hauv lub hnub rau xyoo dhau los ua nkig. Tus kov tuaj yeem snap, lossis phem dua, lub cev tuaj yeem tawg los ntawm kev cuam tshuam me me, ua rau dej nyab loj. Lub valve tshiab kho cov khoom siv lub zog qub. Qhov thib ob yogkev ntseeg tau. Lub drip qeeb los ntawm lub qub valve yog ntau tshaj li cov dej khib nyiab; nws qhia tau hais tias cov seals sab hauv tau ua tsis tiav. Lub valve tshiab nrog cov rooj zaum PTFE tshiab thiab EPDM O-rings muab qhov zoo meej, npuas-nruj kaw koj tuaj yeem suav rau. Peb yogkev ua haujlwm. Thaum muaj xwm txheej ceev, koj yuav tsum kaw cov dej kom sai. Ib qho qub qub uas tawv nrog lub hnub nyoog lossis nplai yog qhov siv tsis tau. Lub valve tshiab hloov tau yooj yim, muab kev tswj tam sim ntawd rau koj. Rau tus nqi me me ntawm avalve, koj rov qab kho qhov kev nyab xeeb, kev ntseeg siab, thiab kev ua haujlwm ntawm qhov tseem ceeb ntawm kev tswj xyuas hauv koj lub cev.
Xaus
txawvPVC li qubua haujlwm tshwj xeeb. Qhov zoo yog txhais los ntawm cov ntaub ntawv ntshiab thiab precision manufacturing, uas ua kom lub neej ntev dua thiab txhim khu kev qha ntau dua li lwm qhov pheej yig.
