Muyenera kutseka madzi, koma chogwirira cha valavu sichingasunthike. Mumagwiritsa ntchito mphamvu zambiri, mukuopa kuti muwaphwanya onse, zomwe zingakupangitseni kukhala ndi vuto lalikulu kwambiri.

Ma valve atsopano a mpira wa PVC ndi ovuta kutembenuza chifukwa cha chisindikizo cholimba komanso chouma pakati pa mipando ya PTFE ndi mpira watsopano wa PVC. Kulimba koyambirira kumeneku kumatsimikizira chisindikizo chosatayikira ndipo nthawi zambiri kumachepa pambuyo pozungulira kangapo.

Mwina ili ndi funso lomwe makasitomala a Budi amafunsa kawirikawiri lokhudza valavu yatsopano. Nthawi zonse ndimamuuza kuti afotokoze kuti izikuuma kwenikweni ndi chizindikiro cha khalidweZimatanthauza kuti valavuyo yapangidwa ndikulolerana kolimba kuti apange chisindikizo chabwino komanso changwiroZiwalo zamkati ndi zatsopano ndipo sizinagwiritsidwe ntchito. M'malo mokhala vuto, ndi chizindikiro chakuti valavuyo idzachita ntchito yake yoletsa madzi kwathunthu. Kumvetsetsa izi kumathandiza kuyang'anira ziyembekezo ndikulimbitsa chidaliro mu chinthucho kuyambira koyamba.

Kodi mungapange bwanji kuti valavu ya mpira wa PVC ikhale yosavuta kutembenuka?

Mukukumana ndi valavu yolimba. Mumayesedwa kuti mugwire wrench yayikulu, koma mukudziwa kuti ikhoza kuswa chogwirira cha PVC kapena thupi lake, zomwe zingasinthe vuto laling'ono kukhala kukonza kwakukulu.

Kuti muchepetse kutembenuka kwa valavu ya PVC, gwiritsani ntchito chida monga cholumikizira cha channel-lock kapena cholumikizira chapadera cha valavu kuti mugwiritse ntchito mphamvu yowonjezera. Gwirani chogwiriracho mwamphamvu pafupi ndi maziko ake ndipo chigwiritseni ntchito molimba komanso mofanana kuti muchizungulire.

Kugwiritsa ntchito mphamvu zambiri ndiyo njira yachangu kwambiri yothyolaValavu ya PVC. Chofunika kwambiri ndi mphamvu, osati mphamvu yamphamvu. Nthawi zonse ndimalangiza Budi kuti agawane njira zoyenera izi ndi makasitomala ake omanga. Choyamba, ngati valavu ndi yatsopano ndipo sinayikidwebe, ndi bwino kutembenuza chogwiriracho mobwerezabwereza. Izi zimathandiza kuti mpira ukhale wolimbana ndi zomangira za PTFE ndipo zimatha kuchepetsa kuuma koyambirira. Ngati valavu yayikidwa kale, njira yabwino kwambiri ndikugwiritsa ntchito chida chothandizira makina. Awrench ya lambaNdibwino kwambiri chifukwa sizingawononge chogwirira, koma ma pliers otsekera njira amagwira ntchito bwino. Ndikofunikira kwambiri kugwira chogwirira pafupi ndi thupi la valavu momwe mungathere. Izi zimachepetsa kupsinjika kwa chogwiriracho ndipo zimayika mphamvu mwachindunji ku tsinde lamkati, kuchepetsa chiopsezo chothyoka pulasitiki.

N’chifukwa chiyani valavu yanga ya mpira ndi yovuta kuitembenuza?

Vavu yakale yomwe kale inkasanduka bwino tsopano yagwidwa. Mukudabwa ngati yasweka mkati, ndipo lingaliro loidula ndi mutu womwe simukusowa.

Vavu ya mpira imakhala yovuta kuyitembenuza pakapita nthawi chifukwa cha mchere wochuluka wochokera m'madzi olimba, zinyalala zomwe zimalowa mu makinawo, kapena zisindikizo zimauma ndi kumamatira patatha zaka zambiri zili pamalo amodzi.

Pamene valavu ikhala yovuta kuitembenuza mtsogolo, nthawi zambiri imakhala chifukwa cha zinthu zachilengedwe, osati vuto la kupanga. Iyi ndi mfundo yofunika kwambiri kuti gulu la Budi limvetsetse popereka madandaulo a makasitomala. Angathe kuzindikira vutolo kutengera zaka za valavuyo ndi momwe imagwiritsidwira ntchito. Pali zifukwa zingapo zomwe zimachitika izi:

Kumvetsetsa zifukwa izi kumathandiza kufotokozera kasitomala kuti kukonza ma valavu, komanso kubwezeretsanso, ndi gawo la moyo wa makina opopera madzi.

Kodi ndingathe kudzola valavu ya mpira wa PVC?

Vavu ndi yolimba, ndipo chibadwa chanu choyamba ndi kupopera WD-40. Koma mukukayikira, mukudabwa ngati mankhwalawo angawononge pulasitiki kapena kuipitsa madzi anu akumwa.

Musagwiritse ntchito mafuta odzola monga WD-40 pa valavu ya PVC. Mankhwalawa amawononga pulasitiki ndi zomatira za PVC. Gwiritsani ntchito mafuta odzola 100% okhala ndi silicone ngati pakufunika kutero.

Ili ndi chenjezo lofunika kwambiri la chitetezo lomwe ndimapereka kwa ogwirizana nafe onse. Pafupifupi mafuta onse opopera, mafuta, ndi mafuta odzola m'nyumba ndi ofala kwambiri.zopangidwa ndi mafutaMafuta oyeretsedwa a petroleum amachititsa kuti pulasitiki ya PVC iwonongeke komanso ikhale yofooka. Kugwiritsa ntchito mafutawa kungayambitse kusweka kwa thupi la valve pakatha maola ambiri kapena masiku angapo. Mafuta okhawo otetezeka komanso oyenera a PVC, EPDM, ndi PTFE ndi awa:Mafuta a silicone 100%Ndi yopanda mankhwala ndipo siidzavulaza zigawo za valavu. Ngati makinawo ndi a madzi akumwa, mafuta a silicone ayeneranso kukhalaSatifiketi ya NSF-61Kuonedwa kuti ndi kotetezeka pa chakudya. Komabe, kugwiritsa ntchito bwino kumafuna kuchepetsa mphamvu ya chingwecho komanso nthawi zambiri kusokoneza valavu. Nthawi zambiri, ngati valavu yakale ndi yolimba kwambiri moti imafunika mafuta, ndi chizindikiro chakuti ikuyandikira mapeto a moyo wake, ndipo kuisintha ndiye njira yotetezeka komanso yodalirika.

Ndi njira iti yosinthira valavu ya mpira wa PVC?

Muli pa valavu, mwakonzeka kuitembenuza. Koma ndi njira iti yotseguka, ndipo ndi njira iti yotsekedwa? Muli ndi mwayi wa 50/50, koma kuganiza molakwika kungayambitse madzi ambiri mwadzidzidzi.

Kuti mutsegule valavu ya mpira wa PVC, tembenuzani chogwirira kuti chigwirizane ndi chitoliro. Kuti muchitseke, tembenuzani chogwiriracho pang'onopang'ono (madigiri 90) kuti chikhale cholunjika ku chitolirocho.

Ili ndiye lamulo lofunika kwambiri pakugwiritsa ntchitovalavu ya mpira, ndipo kapangidwe kake kabwino kamapereka chizindikiro chowoneka nthawi yomweyo. Malo a chogwirira amatsanzira malo a dzenje lomwe lili mkati mwa mpira. Pamene chogwirira chikuyenda mbali yomweyo ndi chitoliro, madzi amatha kudutsa. Pamene chogwirira chidutsa chitoliro kuti chipange mawonekedwe a "T", madzi amatsekeka. Ndimapatsa gulu la Budi mawu osavuta kuti ndiphunzitse makasitomala awo: "Pa mzere, madzi amayenda bwino." Lamulo losavuta ili limachotsa zongoganizira zonse ndipo ndi muyezo wamba wa ma valve a mpira ozungulira kotala, kaya apangidwa ndi PVC, mkuwa, kapena chitsulo. Njira yomwe mumazungulira—mozungulira wotchi kapena mozungulira wotchi—sichinthu chofunikira monga malo omaliza. Kuzungulira madigiri 90 ndiko komwe kumapangitsa ma valve a mpira kukhala achangu komanso osavuta kugwiritsa ntchito potseka mwadzidzidzi.

WolimbaValavu ya PVCnthawi zambiri ndi chizindikiro cha chisindikizo chatsopano, cholimba. Gwiritsani ntchito mphamvu yokhazikika, osawononga mafuta odzola. Pa ntchito, kumbukirani lamulo losavuta: parallel ndi lotseguka, perpendicular ndi yotsekedwa.
