Mwayika valavu yatsopano ya PVC ndipo mukuyembekeza kuti igwire ntchito kwa zaka zambiri. Koma kulephera mwadzidzidzi kungayambitse kusefukira kwa madzi, kuwononga zida, ndikuletsa ntchito.

Wapamwamba kwambiriValavu ya mpira wa PVCimatha kukhala zaka 20 m'malo abwino. Komabe, nthawi yake yeniyeni yogwira ntchito imatsimikiziridwa ndi zinthu monga kuwala kwa UV, kukhudzana ndi mankhwala, kutentha kwa madzi, kuthamanga kwa dongosolo, komanso kangati komwe imagwiritsidwa ntchito.

Chiwerengero cha zaka 20 chimenecho ndi poyambira, osati chitsimikizo. Yankho lenileni ndi lakuti “zimadalira.” Ndinkalankhula za izi ndi Budi, woyang'anira zogula zomwe ndimagwira naye ntchito ku Indonesia. Amaona kuti ma valve athu akuyenda bwino kwambiri patatha zaka 15. Ena, mwatsoka, ma valve akhala akulephera kugwira ntchito pasanathe zaka ziwiri. Kusiyana si valavu yokha, koma malo omwe imakhala. Kumvetsetsa zinthu zachilengedwe izi ndiyo njira yokhayo yodziwira nthawi yomwe valavu yanu idzakhalapo ndikuwonetsetsa kuti ikufika pamlingo wake wonse.

Kodi valavu ya mpira wa PVC imakhala ndi moyo wautali bwanji?

Mukufuna nambala yosavuta ya dongosolo lanu la polojekiti. Koma kuyika nthawi yanu ndi bajeti yanu pamalingaliro ndi koopsa, makamaka ngati valavu yalephera kale musanayembekezere.

Nthawi yotsala ya valavu ya mpira wa PVC imachokera pa zaka zingapo mpaka zaka makumi awiri. Izi sizikukhazikika. Nthawi yomaliza yogwira ntchito imadalira kwathunthu momwe imagwirira ntchito komanso mtundu wa zipangizo zake.

Ganizirani za moyo wa valavu ngati thanki yonse ya gasi. Mumayamba ndi zaka 20. Vuto lililonse lomwe mukuligwiritsa ntchito limagwiritsa ntchito mafutawo mwachangu. Zinthu zazikulu ndi kuwala kwa dzuwa komwe kumachokera ku dzuwa komanso kugwiritsidwa ntchito pafupipafupi. Vavu yoyikidwa panja popanda chitetezo idzakhala yofooka ngatiMa radiation a UV amawononga pulasitiki ya PVC.Pakatha zaka zingapo, imatha kufooka kwambiri kotero kuti kungogogoda pang'ono kungaiswe. Valavu yotsegulidwa ndi kutsekedwa kambirimbiri patsiku imawononga zisindikizo zake zamkati mwachangu kwambiri kuposa kutsekedwa kwa mainline komwe kumazunguliridwa kawiri pachaka. Kutentha kwambiri, ngakhale komwe kuli pansi pa malire ovomerezeka a 60°C, kudzafupikitsabe moyo wake pakapita nthawi poyerekeza ndi vavu yomwe ili pamalo ozizira komanso amdima. Moyo weniweni umachokera ku kufanana ndivalavu yabwinokupita ku malo odekha.

Kodi ma valve a mpira wa PVC amatha nthawi yayitali bwanji?

Mwamva kuti zimatha kukhala kwa zaka zambiri. Koma mwawonanso zina zomwe zimasweka ndi kuoneka zachikasu patatha nyengo zochepa chabe. Izi zimapangitsa kuti zikhale zovuta kuzikhulupirira.

Mu malo otetezeka komanso osavutikira kwambiri monga chingwe cha mapaipi chamkati, valavu ya mpira wa PVC imatha kukhalapo kwa zaka zoposa 20. Komabe, ikayikidwa padzuwa lachindunji komanso ikagwiritsidwa ntchito kwambiri, nthawi yake yogwira ntchito imatha kuchepetsedwa kufika pa zaka 3-5 zokha.

Kusiyana kumeneku ndi chinthu chomwe ndimakambirana ndi Budi nthawi zonse. Ali ndi kasitomala m'modzi, mlimi, yemwe adayika ma valve athu m'nyumba yopopera yotsekedwa ya makina ake othirira zaka 15 zapitazo. Amatetezedwa ku dzuwa ndi nyengo, ndipo amagwira ntchito bwino mpaka lero. Ali ndi kasitomala wina yemwe amayika mapaipi a maiwe osambira padenga. Mapulojekiti ake oyambirira adagwiritsa ntchito ma valve osatetezedwa. Padzuwa lamphamvu la ku Indonesia, ma valve amenewo adayamba kufooka ndipo adayamba kulephera mkati mwa zaka zinayi. Unali valavu yapamwamba kwambiri yomweyi. Kusiyana kokha kunali chilengedwe. Izi zikusonyeza kuti funso silili loti "Vavu imakhala nthawi yayitali bwanji?" koma "Idzakhala nthawi yayitali bwanji?"pamalo enieni awa"Kuteteza valavu ya PVC ku dzuwa, mdani wake wamkulu, ndicho chinthu chofunikira kwambiri chomwe mungachite kuti muwonetsetse kuti yafika nthawi yayitali yogwira ntchito. Chovala chosavuta chautoto wa latexkapenabokosi la valavuakhoza kuwonjezera zaka za moyo.

Kodi ma valve a mpira wa PVC ndi odalirika bwanji?

PVC ndi pulasitiki chabe, ndipo imatha kuoneka yolimba ngati chitsulo. Mumada nkhawa kuti ingasweke kapena kutuluka madzi mukapanikizika ndi zinthu zenizeni, zomwe zingakupangitseni kuwoneka ngati yosadalirika ngati valavu yolemera yamkuwa.

Ma valve apamwamba a PVC ndi odalirika kwambiri pa ntchito zawo. Kapangidwe kawo ka pulasitiki kumatanthauza kuti sakhudzidwa ndi dzimbiri ndi mchere zomwe zimapangitsa kuti ma valve achitsulo alephere kapena kugwidwa pakapita nthawi.

Kudalirika sikungokhala mphamvu chabe; koma kumagwira ntchito nthawi zonse. Valavu yachitsulo imawoneka yolimba, koma m'madzi ambiri, kudalirika kwake kumachepa pakapita nthawi. Michere m'madzi, kapena mankhwala monga chlorine, ingayambitse dzimbiri ndi kukula mkati. Izi zimapangitsa kuti valavu ikhale yolimba komanso yovuta kuyitembenuza. Pomaliza pake, imatha kugwira ntchito kwathunthu, zomwe zimapangitsa kuti ikhale yopanda ntchito pakagwa ngozi. Mavavu a PVC alibe vutoli. Ndi osagwira ntchito m'madzi ndi zinthu zina zomwe zimawonjezeredwa. Sangathe kuchita dzimbiri kapena kuwononga. Pamwamba pamkati pamakhalabe yosalala, ndipo mpira umapitirira kutembenuka mosavuta, ngakhale patatha zaka khumi akugwira ntchito. Uku ndiye kudalirika kwenikweni komwe ndimalankhula ndi makasitomala a Budi. Pakugwiritsa ntchito madzi ozizira, kuyambira maiwe osambira mpaka ulimi wamadzi, valavu ya PVC imapereka kudalirika kwanthawi yayitali komwe chitsulo nthawi zambiri sichingagwirizane nako chifukwa sichingagwire ntchito.

Kodi valavu ya PVC imatenga nthawi yayitali bwanji?

Valavu yanu yasiya kugwira ntchito bwino. Mukudzifunsa ngati yangotha ​​chifukwa cha ukalamba, kapena ngati pali china chake chomwe chachititsa kuti ilephereke kotero mutha kuyiletsa kuti isachitikenso.

Valve ya PVC imatha pamene chinthu chofunikira chalephera kugwira ntchito. Izi nthawi zambiri zimachitika chifukwa cha chimodzi mwa zinthu zitatu: zomangira zamkati zotha ntchito, kuwonongeka kwa UV komwe kumapangitsa thupi kukhala lofooka, kapena kuwonongeka kwakuthupi chifukwa chomangika kwambiri.

Ma valve samangofa ndi ukalamba; gawo linalake limatuluka. Kulephera koyamba komanso kofala kwambiri ndi zisindikizo. Mphete zoyera za PTFE zomwe zimatseka mpirawo ndipo mphete zakuda za EPDM O pa tsinde zimawonongeka chifukwa cha maulendo ambirimbiri otseguka ndi otseka. Izi zimapangitsa kuti pakhale kutayikira pang'ono, kaya kudzera mu chitoliro kapena kutuluka mu chogwirira. Uku ndi kusweka kwachibadwa. Kulephera kwachiwiri ndi thupi lokha. Kuwala kwa UV kumapangitsa PVC kusweka pakapita zaka zambiri. Valavu yogwira ntchito bwino imatha kusweka mwadzidzidzi kuchokera ku nyundo yamadzi kapena kugwedezeka pang'ono. Kulephera kwachitatu kofala kumachitika panthawi yoyika. Anthu nthawi zambiri amagwiritsa ntchito mphamvu zambiri kapena tepi yolumikizira ulusi akamalumikiza ma valve olumikizidwa. Izi zimapangitsa kuti kumapeto kwa ulusi wachikazi kukhale kupanikizika kwambiri, zomwe zimapangitsa kuti tsitsi lizisweka zomwe zingalephereke milungu kapena miyezi ingapo pambuyo pake. Kumvetsetsa njira zolephera izi kumasonyeza kuti nthawi ya moyo wa valavu ndi chinthu chomwe mungathe kuyang'anira ndikuchikulitsa.

Mapeto

Valavu ya PVC yabwino imatha kukhalapo kwa zaka zambiri. Nthawi yake yogwira ntchito imadalira nthawi yochepa koma imadalira kwambiri kugwiritsidwa ntchito moyenera, chitetezo ku kuwala kwa UV, komanso kapangidwe koyenera ka makina ake.
