Mukufulumira kutseka madzi, koma chogwirira cha valve chimamveka ngati chamangidwapo. Mukuwopa kuti kuwonjezera mphamvu zambiri kumangochotsa chogwiriracho.

ChatsopanoValve ya mpira wa PVCndizovuta kutembenuza chifukwa zisindikizo zake zolimba zamkati zimapanga zokwanira bwino, zosadukiza. Vavu yakale nthawi zambiri imakhala yolimba chifukwa cha kuchuluka kwa mchere kapena kusiyidwa pamalo amodzi kwa nthawi yayitali.

Ili ndi funso lomwe ndimayankha ndi mnzanga aliyense watsopano, kuphatikiza gulu la Budi ku Indonesia. Ndizofala kwambiri kotero kuti yankho ndi gawo la maphunziro athu okhazikika. Wogula akamva kuuma koyambako, lingaliro lawo loyamba likhoza kukhala kuti katunduyo ndi wolakwika. Pofotokoza kuti kuuma uku ndi chizindikiro cha chisindikizo chapamwamba, cholimba, timatembenuza madandaulo omwe angakhalepo kukhala chidaliro. Chidziwitso chaching'ono ichi chimathandiza makasitomala a Budi kukhulupirira zinthu za Pntek zomwe akuziyika, kulimbitsa mgwirizano wathu wopambana.

Chifukwa chiyani ma valve a mpira a PVC ndi ovuta kutembenuza?

Mwangotulutsa valavu yatsopano ndipo chogwiriracho chikukana nthawi yanu. Mumayamba kukayikira ngati mwagula chinthu chotsika mtengo chomwe chidzakulepheretseni mukachifuna kwambiri.

ChatsopanoPVC valavu mpirandizovuta kutembenuza chifukwa cha kukangana pakati pa mipando yowuma, yololera kwambiri ya PTFE ndi mpira watsopano wa PVC. Kuwuma koyambiriraku kumatsimikizira kuti chisindikizo changwiro, chotsikirapo chidzapangidwa.

Ndiloleni ndilowe mozama muzopangapanga, popeza izi zikufotokozera zonse. Timapanga ma valve athu a Pntek kwa cholinga chimodzi chachikulu: kuletsa kutuluka kwa madzi kwathunthu. Kuti tichite izi, timagwiritsa ntchito kwambirikulolerana kolimba. Zomwe zili zofunika kwambiri ndi mpira wosalala wa PVC ndi mphete ziwiri zotchedwaPTFE mipando. Mutha kudziwa PTFE ndi dzina lake, Teflon. Mukatembenuza chogwirira, mpirawo umazungulira motsutsana ndi mipando iyi. Mu valavu yatsopano, malo awa amakhala aukhondo komanso owuma. Kutembenuka koyamba kumafuna mphamvu zambiri chifukwa mukugonjetsa kukangana kwapakati pazigawo zatsopanozi. Zili ngati kutsegula mtsuko watsopano; kupotoza koyamba kumakhala kovuta kwambiri chifukwa kumaswa chisindikizo changwiro. Valavu yomwe imatembenuka mosavuta kuyambira poyambira imatha kukhala ndi kulolerana kosalekeza, komwe kungayambitse kutsika pang'onopang'ono pakupanikizika. Kotero, kuuma koyambirira kumeneko ndi umboni wabwino kwambiri womwe muli nawo wa valve yopangidwa bwino, yodalirika.

Kodi mungadziwe bwanji ngati valavu ya PVC ndi yoyipa?

Vavu yanu sikugwira ntchito bwino. Simukutsimikiza ngati yangokakamira ndipo ikufunika mphamvu, kapena ngati yathyoka mkati ndipo ikufunika kusinthidwa.

Valavu ya PVC ndi yoyipa ngati ikutuluka kuchokera ku chogwirira kapena m'thupi, imalola madzi kudutsa ikatsekedwa, kapena ngati chogwiriracho chikutembenuka popanda kuletsa kutuluka. Kuumirira pakokha si chizindikiro cha kulephera.

Kwa makasitomala amakampani a Budi, kudziwa kusiyana pakati pa valavu yolimba ndi valavu yoyipa ndikofunikira kuti mupange chisankho choyenera. Valavu yoyipa imakhala ndi zizindikiro zomveka bwino zomwe zimapitilira kungokhala kovuta kutembenuka. Ndikofunika kuyang'ana zizindikiro zenizeni izi.

Kuuma kwa valve yatsopano ndikwachilendo. Komabe, ngati valavu yakale yomwe inkatembenuka mosavuta imakhala yolimba kwambiri, nthawi zambiri imalozakuchuluka kwa minerals mkati. Ngakhale kuti si "zoipa" ponena za kusweka, zimasonyeza kuti valve ili kumapeto kwa moyo wake wothandiza ndipo iyenera kukonzedwa kuti ilowe m'malo.

Kodi mafuta abwino kwambiri a mavavu a mpira ndi ati?

Chidziwitso chanu chimakuuzani kuti mutenge mafuta opopera kuti mukhale ndi valve yolimba. Koma mukukayikira, poopa kuti mankhwalawo atha kufooketsa pulasitiki kapena kuwononga mzere wamadzi.

Mafuta okhawo otetezeka komanso ogwira mtima a mavavu a mpira wa PVC ndi 100% mafuta opangidwa ndi silikoni. Osagwiritsa ntchito mafuta a petroleum monga WD-40, chifukwa amapangitsa PVC kukhala brittle ndikupangitsa kuti iphwanyike.

Uwu ndiye upangiri wofunikira kwambiri wachitetezo womwe ndingapereke, ndipo ndikuwonetsetsa kuti gulu lonse la Budi likumvetsetsa. Kugwiritsa ntchito mafuta olakwika ndikoyipa kuposa kusagwiritsa ntchito mafuta konse. Zogulitsa wamba zapakhomo monga WD-40, mafuta odzola, ndi mafuta ofunikira kwambiri ndi opangidwa ndi petroleum. Mankhwalawa sagwirizana ndi PVC. Amakhala ngati zosungunulira, akuphwanya pang'onopang'ono kapangidwe kake ka pulasitiki. Izi zimapangitsa PVC kukhala yolimba komanso yofooka. Vavu yothiridwa mafuta motere ikhoza kusinthika mosavuta lero, koma imatha kusweka ndikuphulika mopanikizika mawa. Zomwe zili zotetezeka ku thupi la PVC, mphete za EPDM O, ndi mipando ya PTFE ndi100% mafuta a silicone. Silicone ndi inert yamankhwala, kutanthauza kuti sichitha kapena kuwononga zida za valve. Kwa makina omwe amanyamula madzi akumwa, ndikofunikira kuti mafuta a silicone nawonso akhale ovomerezeka "NSF-61” kuonetsetsa kuti ilibe chakudya.

Kodi mavavu a mpira amakakamira?

Simunafunikire kugwiritsa ntchito valavu yapadera yotsekera kwa zaka. Tsopano pali zadzidzidzi, koma mukapita kukatembenuza, chogwiriracho chimakhala chozizira kwambiri, chikukana kusuntha konse.

Inde, mavavu a mpira amakakamira, makamaka ngati sagwiritsidwa ntchito kwa nthawi yayitali. Zoyambitsa zazikulu ndi kuchuluka kwa mchere kuchokera kumadzi olimba kumangirira mpira m'malo mwake kapena zisindikizo zamkati kumamatira.

Izi zimachitika nthawi zonse, ndipo ndi vuto lomwe limabwera chifukwa cha kusagwira ntchito. Vavu ikakhala pamalo amodzi kwa zaka zambiri, makamaka m'dera lomwe lili ndi madzi olimba ngati gawo lalikulu la Indonesia, zinthu zingapo zimatha kuchitika mkati. Nkhani yofala kwambiri ndikuchuluka kwa mineral. Madzi amakhala ndi mchere wosungunuka monga calcium ndi magnesium. Pakapita nthawi, mcherewu ukhoza kuyika pamwamba pa mpira ndi mipando, ndikupanga kutumphuka kolimba kofanana ndi konkriti. Sikelo iyi imatha kuyika mpirawo pamalo otseguka kapena otsekedwa. Chifukwa china chofala ndicho kumamatira kosavuta. Mipando yofewa ya PTFE imatha kumamatira pang'onopang'ono kapena kumamatira ku mpira wa PVC pakapita nthawi ngati yapanikizidwa popanda kusuntha. Nthawi zonse ndimauza Budi kuti alimbikitse "kuteteza zoteteza” Kwa makasitomala ake.” Pa ma valve ofunika otsekera, ayenera kungotembenuza chogwiriracho kamodzi kapena kawiri pachaka.” Kutembenukira mwachangu pamalo otsekeka ndi kubwereranso kuti atsegule zimangofunika kuti athyole sikelo yaing’ono iliyonse ndi kuteteza zosindikizira kuti zisamamatire.
