Mukuona valavu ya mpira ya PVC, ndipo mtengo wake wotsika umakupangitsani kukayikira. Kodi pulasitiki ingakhaledi gawo lodalirika pamakina anga amadzi? Chiwopsezo chikuoneka chachikulu.

Inde, ma valve apamwamba a mpira a PVC si abwino okha; ndi abwino kwambiri komanso odalirika kwambiri pa ntchito zawo. Valavu yopangidwa bwino yopangidwa ndi PVC yoyambirira yokhala ndi mipando yolimba ya PTFE ipereka chithandizo cha zaka zambiri chosatulutsa madzi m'makina ozizira.

Ndimakumana ndi lingaliro limeneli nthawi zonse. Anthu amaona "pulasitiki" ndipo amaganiza kuti "ndi yotsika mtengo komanso yofooka." Mwezi watha, ndinali kulankhula ndi Budi, manejala wogula yemwe ndimagwira naye ntchito ku Indonesia. Mmodzi mwa makasitomala ake atsopano, kampani yogulitsa ulimi, anali kukayikira kugwiritsa ntchito njira yathu.Ma valve a PVCchifukwa cha njira yawo yatsopano yothirira. Iwo nthawi zonse ankagwiritsa ntchito njira zodula kwambirimavavu achitsulo. Ndinalimbikitsa Budi kuti awapatse zitsanzo. Patatha milungu iwiri, kasitomala anabwerera, akudabwa. Ma valve athu anali atakumana ndi feteleza komanso chinyezi chosalekeza popanda chizindikiro chilichonse cha dzimbiri lomwe linali litawononga ma valve awo akale achitsulo. Zonse ndi kugwiritsa ntchito zipangizo zoyenera pantchitoyo, ndipo pa ntchito zambiri, PVC ndiye chisankho chabwino kwambiri.

Kodi valavu ya mpira wa PVC imatenga nthawi yayitali bwanji?

Mukupanga dongosolo ndipo muyenera kudziwa nthawi yomwe ziwalo zanu zidzagwira ntchito. Kusintha ma valve olephera nthawi zonse ndi kutaya nthawi, ndalama, komanso ndi vuto lalikulu.

Valavu ya mpira ya PVC yapamwamba kwambiri imatha kupirira zaka 10 mpaka 20 mosavuta, ndipo nthawi zambiri imakhala yayitali kwambiri ngati zinthu zili bwino. Nthawi yake yogwira ntchito imadalira kwambiri mtundu wa chinthu chomwe chimapangidwira, kuwala kwa UV, madzi, komanso kuchuluka kwa momwe chimagwiritsidwira ntchito.

Moyo wa valavu ya PVC si nambala imodzi yokha; ndi chifukwa cha zinthu zingapo. Chofunika kwambiri ndi mtundu wa zipangizo zopangira. Ku Pntek, timalimbikira kugwiritsa ntchitoUtomoni wa PVC wa 100% wosasinthikaMa valve otsika mtengo amagwiritsa ntchito "regrind," kapena pulasitiki yobwezeretsedwanso, yomwe imatha kuphwanyika komanso yosayembekezereka. Chinthu chachiwiri chachikulu ndikugwiritsa ntchito. Kodi ndi m'nyumba kapena panja?

Kuchuluka kwa ma frequency kudzavala mipando ndi zisindikizo mwachangu. Koma pakugwiritsa ntchito madzi ozizira nthawi zonse mkati mwa mphamvu yake, valavu ya mpira ya PVC yopangidwa bwino ndi gawo lenileni la nthawi yayitali. Mutha kuyiyika ndikuyiwala kwa zaka zambiri.

Zinthu Zomwe Zimakhudza Moyo wa Valve ya PVC

Kodi ma valve a mpira wa PVC ndi odalirika bwanji?

Mukufuna gawo lomwe mungadalire kwambiri. Kulephera kwa valavu imodzi kungathe kuyimitsa ntchito yanu yonse, zomwe zingachititse kuchedwa komanso kuwononga ndalama zambiri kuti ikonze.

Pa cholinga chawo—chowongolera madzi ozizira otsegula/otseka—ma valve apamwamba a PVC ndi odalirika kwambiri. Kudalirika kwawo kumachokera ku kapangidwe kosavuta kokhala ndi zinthu zochepa zosuntha komanso zinthu zomwe sizimakhudzidwa ndi dzimbiri ndi dzimbiri, zomwe ndi zinthu zazikulu zomwe ma valve achitsulo amalephera kugwira ntchito.

Kudalirika kwa valavu sikungokhala mphamvu yake yokha; koma kumangokhudza kukana kwake ku zolephera zomwe zimachitika kawirikawiri. Apa ndi pomwe PVC imapambana. Taganizirani za valavu yachitsulo yomwe ili pansi pamadzi kapena yobisika panja. Pakapita nthawi, idzapsa. Chogwiriracho chingapse, thupi likhoza kuwonongeka. Vavu ya PVC siikhudzidwa ndi izi. Budi nthawi ina idagulitsa mavavu athu ku bizinesi yolima nsomba m'mphepete mwa nyanja yomwe inkasintha mavavu amkuwa miyezi 18 iliyonse chifukwa cha dzimbiri la madzi amchere. Patatha zaka zisanu, mavavu athu oyambirira a PVC akadali kugwira ntchito bwino. Chinsinsi china chodalirika ndi kapangidwe ka zisindikizo. Mavavu otsika mtengo amagwiritsa ntchito mphete imodzi ya rabara pa tsinde. Apa ndi malo ofala otayikira madzi. Tinapanga mavavu athu ndimphete ziwiri za O, kupereka chisindikizo chowonjezera chomwe chimatsimikizira kuti chogwiriracho sichiyamba kudontha. Kapangidwe kosavuta komanso kolimba aka ndi komwe kamapangitsa kuti zikhale zodalirika kwambiri.

Kumene Kudalirika Kumachokera

Ndi ma valve ati abwino a mkuwa kapena PVC foot?

Mukukhazikitsa pampu ndipo mukufuna valavu ya phazi. Sankhani chinthu cholakwika, ndipo mutha kukumana ndi dzimbiri, kuwonongeka, kapena kuipitsa madzi omwe mukuyesera kupompa.

Palibe chilichonse mwa izi chomwe chili chabwino kuposa china chilichonse; kusankha kumadalira momwe mungagwiritsire ntchito.Valavu ya phazi la PVCndi bwino pa ntchito zowononga madzi ndi zotsika mtengo. Valavu ya phazi la mkuwa ndi yabwino chifukwa cha mphamvu zake zakuthupi motsutsana ndi kugundana komanso chifukwa cha kuthamanga kwambiri kapena kutentha.

Tiyeni tifotokoze mwachidule izi. Valavu ya phazi ndi mtundu wa valavu yoyezera yomwe imakhala pansi pa chingwe chokokera cha pampu, ndikusunga pampuyo ili yokonzeka. Ntchito yayikulu ndikuletsa madzi kuti asatuluke. Apa, kusankha zinthu ndikofunikira kwambiri. Ubwino woyamba waPVCndi kukana dzimbiri kwake. Ngati mukupopa madzi a m'chitsime okhala ndi mchere wambiri, kapena madzi ochokera m'dziwe loti alime, PVC ndiye wopambana. Mkuwa ukhoza kuvutika ndi dezincization, pomwe mchere m'madzi umatuluka mu zinc kuchokera mu alloy, zomwe zimapangitsa kuti ikhale ndi mabowo komanso yofooka. PVC nayonso ndi yotsika mtengo kwambiri. Ubwino waukulu wamkuwandi kulimba kwake. Ndi kolimba kwambiri ndipo kumatha kupirira kugwetsedwa m'chitsime kapena kugundana ndi miyala popanda kusweka. Pazitsime zakuya kwambiri kapena ntchito zovuta zamafakitale komwe mphamvu zakuthupi ndizofunikira kwambiri, mkuwa ndi chisankho chotetezeka.

Valavu ya PVC vs. Brass Foot: Ndi iti yomwe mungasankhe?

Kodi ma valve a mpira wa PVC amalephera?

Mukufuna kuyika gawo kenako nkuliiwala. Koma kunyalanyaza momwe gawo lingawonongekere ndi njira yobweretsera tsoka, zomwe zimapangitsa kuti pakhale kutayikira, kuwonongeka, komanso kukonza mwadzidzidzi.

Inde, monga mbali ina iliyonse ya makina, mavavu a mpira a PVC amatha kulephera. Kulephera nthawi zambiri kumachitika chifukwa chogwiritsa ntchito molakwika, monga kuwagwiritsa ntchito ndi madzi otentha kapena mankhwala osagwirizana, kuwonongeka kwakuthupi monga kuzizira, kapena kuwonongeka kosavuta pa valavu yosakhala yabwino.

KumvetsetsaBwanjiKulephera ndiko chinsinsi chopewera izi. Kulephera kwakukulu kwambiri ndi kusweka kwa thupi. Izi nthawi zambiri zimachitika pazifukwa ziwiri: kumangitsa kwambiri cholumikizira cha ulusi, chomwe chimaika mphamvu yayikulu pa valavu, kapena kulola madzi kuzizira mkati mwake. Madzi amafutukuka akazizira, ndipo amagawa valavu ya PVC momasuka. Kulephera kwina kofala ndikutuluka kwa madzi. Kumatha kutuluka kuchokera pa chogwirira ngati tsindeMphete za OKutha—chizindikiro chosonyeza valavu yotsika mtengo. Kapena, ingalephere kuzimitsidwa kwathunthu. Izi zimachitika mpira kapena mipando ikakanda ndi grit mu payipi kapena kutha chifukwa chogwiritsa ntchito molakwika valavu ya mpira kuti iyende bwino. Nthawi zonse ndimauza Budi kuti akumbutse makasitomala ake: kuyika bwino, kuigwiritsa ntchito pokhapokha ngati madzi ozizira atseka, ndikugula valavu yabwino poyamba. Ngati muchita zinthu zitatuzi, mwayi woti mulephere umakhala wotsika kwambiri.
