Mukuwona valavu ya mpira wa PVC, ndipo mtengo wake wotsika umakupangitsani kukayikira. Kodi pulasitiki ingakhaledi gawo lodalirika pamadzi anga? Chiwopsezocho chikuwoneka chachikulu.

Inde, mavavu apamwamba kwambiri a PVC si abwino; ndiabwino kwambiri komanso odalirika kwambiri pazomwe akufuna. Valavu yopangidwa bwino kuchokera ku namwali PVC yokhala ndi mipando yolimba ya PTFE idzapereka zaka zambiri zautumiki wopanda kutayikira m'madzi ozizira.

Ndimakhala ndi malingaliro awa nthawi zonse. Anthu amawona "pulasitiki" ndikuganiza "zotsika mtengo komanso zofooka." Mwezi watha, ndinali kulankhula ndi Budi, bwana wogula amene ndimagwira naye ntchito kwambiri ku Indonesia. M'modzi mwa makasitomala ake atsopano, kampani yapa famu, anali wokayika kugwiritsa ntchito yathuMavavu a PVCkwa njira yawo yatsopano yothirira. Nthawi zonse ankagwiritsa ntchito zodulavalavu zitsulo. Ndinalimbikitsa Budi kuwapatsa zitsanzo. Patatha milungu iwiri, kasitomalayo adabweranso, akudabwa. Mavavu athu anali atakumana ndi feteleza ndi chinyezi chokhazikika popanda chizindikiro chimodzi cha dzimbiri chomwe chinasokoneza ma valve awo akale achitsulo. Zonse zokhudzana ndi kugwiritsa ntchito zinthu zoyenera pantchitoyo, komanso ntchito zambiri, PVC ndiye chisankho chabwino kwambiri.

Kodi valavu ya PVC imatha nthawi yayitali bwanji?

Mukupanga dongosolo ndipo muyenera kudziwa kuti mbali zanu zizikhala nthawi yayitali bwanji. Nthawi zonse kusintha mavavu olephera ndikuwononga nthawi, ndalama, ndipo ndi vuto lalikulu.

Valavu yapamwamba kwambiri ya PVC imatha kukhalapo kwa zaka 10 mpaka 20, ndipo nthawi zambiri imakhala yotalikirapo pamikhalidwe yabwino. Kutalika kwa moyo wake kumadalira kwambiri kupanga, kuwonekera kwa UV, chemistry yamadzi, komanso momwe amagwiritsidwira ntchito pafupipafupi.

Kutalika kwa moyo wa vavu ya PVC si nambala imodzi yokha; ndi zotsatira za zinthu zingapo. Chofunika kwambiri ndi khalidwe la zopangira. Ku Pntek, timalimbikira kugwiritsa ntchito100% PVC utomoni namwali. Mavavu otsika mtengo amagwiritsa ntchito “regrind,” kapena pulasitiki yokonzedwanso, yomwe ingakhale yolimba komanso yosadziŵika bwino. Chinthu chachiwiri chachikulu ndicho kugwiritsa ntchito. Ndi m'nyumba kapena kunja? PVC yokhazikika imatha kukhala yolimba pakapita nthawi ndi dzuwa, chifukwa chake timaperekaZosankha zosagwira UVkwa mapulogalamu amenewo. Kodi valavu imatembenuzidwa kamodzi patsiku kapena kamodzi pachaka? Mafupipafupi apamwamba adzavala mipando ndi kusindikiza mofulumira. Koma pakugwiritsa ntchito madzi ozizira mkati mwa kukakamiza kwake, valavu ya mpira wa PVC yopangidwa bwino ndi gawo lenileni la nthawi yayitali. Mutha kuyiyika ndikuyiwala kwa zaka zambiri.

Zinthu Zomwe Zimakhudza Moyo Wavavu wa PVC

Kodi mavavu a mpira a PVC ndi odalirika bwanji?

Muyenera gawo lomwe mungadalirepo. Kulephera kwa valve imodzi kungapangitse ntchito yanu yonse kuyimitsidwa, kuchititsa kuchedwa ndi kuwononga ndalama zambiri kukonza.

Pazolinga zawo - madzi ozizira pa / off control - apamwamba PVC mpira mavavu ndi odalirika kwambiri. Kudalirika kwawo kumachokera ku mapangidwe osavuta okhala ndi magawo ochepa osuntha ndi zinthu zomwe sizimakhudzidwa ndi dzimbiri ndi dzimbiri, zomwe zimalephera kwambiri ma valve achitsulo.

Kudalirika kwa valve sikungowonjezera mphamvu zake; ndi za kukana kwake zolephera wamba. Apa ndi pamene PVC imapambana. Ganizirani za valve yachitsulo m'chipinda chapansi chonyowa kapena kukwiriridwa panja. M'kupita kwa nthawi, izo zidzawononga. Chogwiririra chikhoza kuchita dzimbiri, thupi likhoza kunyonyotsoka. Valavu ya PVC imatetezedwa ku izi. Budi nthawi ina anagulitsa ma valve athu ku bizinesi ya m'nyanja ya m'mphepete mwa nyanja yomwe inkasintha mavavu amkuwa miyezi 18 iliyonse chifukwa cha dzimbiri la madzi amchere. Zaka zisanu pambuyo pake, mavavu athu oyambirira a PVC akugwirabe ntchito bwino. Chinsinsi china cha kudalirika ndi mapangidwe a zisindikizo. Mavavu otsika mtengo amagwiritsa ntchito mphira imodzi ya O-ring pa tsinde. Iyi ndi malo omwe anthu ambiri amadumphira nawo. Tinapanga ma valve athu ndiawiri O-mphete, kupereka chisindikizo chowonjezera chomwe chimatsimikizira chogwiriracho kuti chisayambe kudontha. Mapangidwe osavuta, olimba awa ndi omwe amawapangitsa kukhala odalirika.

Kumene Kudalirika Kumachokera

Ndi mavavu a mapazi a PVC abwino ndi ati?

Mukukhazikitsa pampu ndipo mukufuna valavu ya phazi. Sankhani zinthu zolakwika, ndipo mutha kukumana ndi dzimbiri, kuwonongeka, kapena kuyipitsa madzi omwe mukuyesera kupopa.

Ngakhale zili bwino konsekonse; kusankha zimadalira ntchito. APVC phazi valvendi yabwino kwa madzi owononga komanso ntchito zotsika mtengo. Valavu ya phazi la mkuwa ndi yabwino chifukwa cha mphamvu zake zolimbana ndi mphamvu komanso kuthamanga kwambiri kapena kutentha.

Tiyeni tifotokoze izi. Valavu ya phazi ndi mtundu wa valavu yowunikira yomwe imakhala pansi pa mzere woyamwa wa mpope, ndikusunga mpope. Ntchito yayikulu ndikuletsa madzi kuti asabwererenso pansi. Apa, kusankha kwakuthupi ndikofunikira. Ubwino woyamba waZithunzi za PVCndi kukana dzimbiri. Ngati mukupopa madzi abwino okhala ndi mchere wambiri, kapena madzi ochokera ku dziwe laulimi, PVC ndiye wopambana bwino. Mkuwa ukhoza kuvutika ndi dezincification, kumene mchere m'madzi umatulutsa zinc kuchokera ku alloy, ndikupangitsa kuti ikhale yofooka komanso yofooka. PVC ndi yotsika mtengo kwambiri. Ubwino waukulu wamkuwandi kupusa kwake. Ndiwolimba kwambiri ndipo imatha kugwetsedwa pansi pachitsime kapena kugundidwa ndi miyala popanda kusweka. Kwa zitsime zakuya kwambiri kapena kugwiritsa ntchito movutikira m'mafakitale komwe mphamvu zakuthupi ndizofunikira kwambiri, mkuwa ndi chisankho chotetezeka.

PVC vs. Brass Foot Valve: Sankhani Iti?

Kodi mavavu a PVC amalephera?

Mukufuna kukhazikitsa gawo ndikuyiwala za izo. Koma kunyalanyaza momwe gawolo lingalephereke ndi njira yobweretsera tsoka, zomwe zimapangitsa kutayikira, kuwonongeka, ndi kukonza mwadzidzidzi.

Inde, monga gawo lililonse lamakina, mavavu a PVC amatha kulephera. Zolephera nthawi zambiri zimayamba chifukwa cha kugwiritsira ntchito molakwika, monga kuzigwiritsa ntchito ndi madzi otentha kapena mankhwala osagwirizana, kuwonongeka kwa thupi monga kuzizira, kapena kuvala kosavuta pa valve yotsika kwambiri.

KumvetsetsaBwanjiamalephera ndiye chinsinsi chopewera. Kulephera koopsa kwambiri ndikusweka kwa thupi. Izi nthawi zambiri zimachitika pazifukwa ziwiri: kumangitsa kwambiri chingwe cha ulusi, chomwe chimayika kupsinjika kwakukulu pa valve, kapena kulola kuti madzi aziundana mkati mwake. Madzi amawonjezeka akaundana, ndipo amatsegula valavu ya PVC. Kulephera kwina kofala ndikuchucha. Ikhoza kutayikira pa chogwirira ngati tsindeO-mphetekutha—chizindikiro chodziŵika bwino cha valavu yotsika mtengo. Kapena, ikhoza kulephera kuzimitsa kwathunthu. Izi zimachitika pamene mpira kapena mipando imakandidwa ndi grit mu payipi kapena kutha chifukwa chogwiritsa ntchito molakwika valavu ya mpira kuti imveke bwino. Nthawi zonse ndimauza Budi kuti akumbutse makasitomala ake: khazikitsani moyenera, mugwiritseni ntchito potseka madzi ozizira okha, ndikugula valavu yabwino poyamba. Mukachita zinthu zitatu izi, mwayi wolephera umakhala wotsika kwambiri.
