Mwayika valavu yatsopano ya PVC ndipo mukuyembekeza kuti idzagwira ntchito kwa zaka zambiri. Koma kulephera kwadzidzidzi kungayambitse kusefukira kwa madzi, kuwononga zida, ndi kutseka ntchito.

Valavu yapamwamba kwambiri ya PVC imatha kukhala zaka 20 m'malo abwino. Komabe, moyo wake weniweni umatsimikiziridwa ndi zinthu monga kuwonekera kwa UV, kukhudzana ndi mankhwala, kutentha kwa madzi, kupanikizika kwamachitidwe, komanso kangati komwe kumagwiritsidwa ntchito.

Chiwerengero cha zaka 20 chimenecho ndi poyambira, osati chitsimikizo. Yankho lenileni ndi "zimadalira." Ndinkalankhula za izi ndi Budi, woyang'anira zogula yemwe ndimagwira naye ntchito ku Indonesia. Amawona mawonekedwe onse. Makasitomala ena ateroma valve athuzikuyenda bwino mu machitidwe azaulimi pambuyo pa zaka 15. Ena akhala ndi mavavu akulephera mkati mwa zaka ziwiri. Kusiyanitsa sikuli konse valavu yokha, koma malo omwe amakhalamo. Kumvetsetsa zinthu zachilengedwe izi ndi njira yokhayo yodziwira kuti valavu yanu idzakhala nthawi yayitali bwanji ndikuwonetsetsa kuti ikukwaniritsa mphamvu zake zonse.

Kodi valavu ya mpira wa PVC ndi yotani?

Mukufuna nambala yosavuta ya dongosolo lanu la polojekiti. Koma kuyika nthawi yanu ndi bajeti pazolinga ndizowopsa, makamaka ngati valavu ikulephera nthawi yayitali musanayembekezere.

Kutalika kwa moyo wa vavu ya mpira wa PVC kumayambira zaka zingapo mpaka zaka makumi awiri. Izi sizinakhazikitsidwe. Kutalika kwa moyo kumadalira kwathunthu malo ake ogwirira ntchito komanso mtundu wa zida zake.

Ganizirani za moyo wa vavu ngati bajeti. Zimayamba pa zaka 20, ndipo vuto lililonse lopweteka "limawononga" zina mwa moyo umenewo mofulumira. Zowononga kwambiri ndi kuwala kwa dzuwa kwa UV komanso kugwiritsidwa ntchito pafupipafupi. Valovu yomwe imatsegulidwa ndi kutsekedwa kambirimbiri patsiku imatha zisindikizo zake zamkati mwachangu kuposa yomwe imatembenuzidwa kamodzi pamwezi. Momwemonso, valavu yomwe imayikidwa panja padzuwa lolunjika idzakhala yolimba komanso yofooka pakapita nthawi. Ma radiation a UV amawononga ma cell a PVC. Pambuyo pa zaka zingapo, imatha kukhala yosalimba kwambiri kotero kuti kugogoda kwapang'ono kungasokoneze. Kugwirizana kwa mankhwala, kutentha kwambiri, ndi kuthamanga kwambiri kumachepetsanso moyo wake. Avalavu yabwinozopangidwa kuchokera ku 100% namwali PVC yokhala ndi mipando yolimba ya PTFE idzakhala nthawi yayitali kuposa valve yotsika mtengo yokhala ndi zodzaza, koma ngakhale valavu yabwino kwambiri idzalephera msanga ngati itagwiritsidwa ntchito molakwika.

Zinthu Zomwe Zimachepetsa Moyo Wavavu wa PVC

Kodi mavavu a mpira a PVC ndi odalirika bwanji?

PVC imawoneka ngati pulasitiki, ndipo pulasitiki imatha kumva kufooka. Mumadandaula kuti ikhoza kusweka kapena kutayikira pansi pa kupanikizika, makamaka poyerekeza ndi valve heavy metal.

Mavavu apamwamba kwambiri a mpira wa PVC ndi odalirika kwambiri pazomwe akufuna. Kupanga kwawo pulasitiki kumatanthauza kuti satetezedwa kwathunthu ku dzimbiri ndi mineral buildup zomwe zimapangitsa kuti ma valve achitsulo alephere kapena kulanda pakapita nthawi.

Kudalirika sikungophulika. Ndi za ngati valavu amagwira ntchito pamene mukuifuna. Budi anandiuza nkhani ya m’modzi mwa makasitomala ake pantchito yolima m’madzi. Ankagwiritsa ntchito ma valve a mpira wamkuwa, koma madzi amchere pang'ono amawapangitsa kuti achite dzimbiri. Patatha chaka chimodzi, mavavuwo anali olimba chifukwa cha dzimbiri moti sankatha kuwatembenuza. Anayenera kusinthidwa. Anasinthira ku ma valve athu a mpira a PVC. Zaka zisanu pambuyo pake, mavavu a PVC omwewo akutembenuka bwino monga tsiku lomwe anaikidwa. Uku ndiye kudalirika kwenikweni kwa PVC. Sizichita dzimbiri. Simatsekedwa ndi sikelo kapena mineral deposits. Malingana ngati ikugwiritsidwa ntchito mkati mwa malire ake opanikizika / kutentha ndi kutetezedwa ku UV, ntchito yake sichitha. Valve yabwino ya PVC yokhala ndi zosalalaPTFE mipandondi odalirikaEPDM O-mpheteamapereka mlingo wa nthawi yaitali, kudalirika zodziwikiratu kuti zitsulo zambiri sizingafanane mu ntchito madzi.

Kodi mavavu a mpira ndi abwino kwa nthawi yayitali bwanji?

Mukuyerekeza valavu ya PVC ndi yamkuwa. Chitsulocho chimamveka cholemera, ndiye chiyenera kukhala bwino, chabwino? Lingaliro ili likhoza kukutsogolerani kusankha valavu yolakwika pa ntchitoyo.

Ma valve a mpira ndi abwino kwa zaka zambiri akagwiritsidwa ntchito moyenera. Kwa PVC, izi zikutanthauza kugwiritsa ntchito madzi ozizira popanda kukhudzidwa mwachindunji ndi UV. Kwachitsulo, kumatanthauza madzi oyera, osawononga. AValve ya PVCnthawi zambiri amatuluka avalve yachitsulom'malo aukali.

"Zikhala bwino mpaka liti?" ndi funso loti "Ndibwino kwa chiyani?" Valavu yamtengo wapatali yosapanga dzimbiri ndi yosangalatsa, koma si yabwino kusankha dziwe losambira lomwe lili ndi madzi a chlorine, omwe amatha kumenyana ndi zitsulo pakapita nthawi. Valavu yamkuwa ndiyabwino kwambiri pazolinga zonse, koma imalephera m'machitidwe okhala ndi feteleza ena kapena madzi acidic. Apa ndi pamene PVC imawala. Ndilo chisankho chabwino kwambiri pamitundu yambiri yogwiritsira ntchito madzi, kuphatikiza ulimi wothirira, ulimi wamadzi, maiwe, ndi mapaipi wamba. M'malo awa, sichingawonongeke, choncho imagwira ntchito bwino kwa zaka zambiri. Ngakhale sibwino kwa madzi otentha kapena kupanikizika kwakukulu, ndiye chisankho chabwino kwambiri pa niche yake yeniyeni. Vavu ya PVC yogwiritsidwa ntchito moyenera idzakhala "yabwino" yotalika kwambiri kuposa valavu yachitsulo yogwiritsidwa ntchito molakwika. Makasitomala opambana a Budi ndi omwe amafananiza zida za valve ndi madzi, osati kungowona mphamvu.

Kodi mavavu a mpira amawonongeka?

Vavu yanu yasiya kugwira ntchito. Mumadzifunsa ngati chinatha kapena ngati china chake chinachititsa kuti chilephereke. Kudziwa chifukwa chake zinalephereka ndiye chinsinsi chopewera nthawi ina.

Inde, mavavu a mpira amawonongeka pazifukwa zingapo zomveka. Zolephera zofala kwambiri ndi zisindikizo zotopa chifukwa chogwiritsidwa ntchito pafupipafupi, kuwonongeka kwa UV kumayambitsa brittleness, kuukira kwamankhwala pazida, kapena kuwonongeka kwakuthupi chifukwa chakukhudzidwa kapena kumangika kwambiri.

Mavavu a mpira samangosiya kugwira ntchito chifukwa cha ukalamba; gawo linalake limalephera. Zomwe zimalephera kwambiri ndi zisindikizo zamkati. Mipando ya PTFE yomwe imasindikiza mpira imatha kuwonongeka pambuyo pa masauzande ambiri otseguka / otseka, zomwe zimatsogolera kudontha pang'ono. Mphete za EPDM O pa tsinde zimathanso kutha, zomwe zimapangitsa kuti pakhale kutayikira. Uku ndi kung'ambika kwabwinobwino. Chifukwa chachiwiri chachikulu ndikuwononga chilengedwe. Monga tinakambilana, kuwala kwa UV ndikupha, kumapangitsa kuti ma valve awonongeke. Mankhwala olakwika amatha kutembenuza PVC kukhala yofewa kapena kuwononga mphete za O. Njira yachitatu yomwe amapitira moyipa ndikuyika molakwika. Cholakwika chofala chomwe ndikuwona ndi chakuti anthu amalimbitsa kwambiri mavavu a PVC. Amakulunga tepi yochuluka kwambiri ya ulusi ndiyeno amagwiritsa ntchito wrench yaikulu, yomwe imatha kuthyola thupi la valve polumikiza. Kumvetsetsa njira zolephera izi kumakuthandizani kuti muteteze ndalama zanu ndikuwonetsetsa kuti zikhalitsa.

Mapeto

Valavu yabwino ya PVC imatha kukhala kwa zaka zambiri. Kutalika kwa moyo wake kumadalira nthawi yocheperako komanso kugwiritsa ntchito moyenera, kutetezedwa ku kuwala kwa UV, komanso kapangidwe kake koyenera kagwiritsidwe ntchito kake.
