Mukufulumira kutseka madzi, koma chogwirira cha valavu chikuwoneka ngati chakhazikika pamalo pake. Mukuopa kuti kuwonjezera mphamvu kungangodula chogwiriracho.

Funso limene ndimafunsa ndi mnzanu aliyense watsopano, kuphatikizapo gulu la Budi ku Indonesia. Ndizofala kwambiri moti yankho lake ndi gawo la maphunziro athu wamba. Kasitomala akamaona kuti kuuma koyambirirako kuli koyenera, lingaliro lake loyamba lingakhale lakuti chinthucho chili ndi vuto. Mwa kufotokoza kuti kuuma kumeneku ndi chizindikiro cha chisindikizo chapamwamba komanso cholimba, timasandutsa madandaulo kukhala mfundo yodzidalira. Chidziwitso chaching'ono ichi chimathandiza makasitomala a Budi kudalira zinthu za Pntek zomwe akuyika, kulimbitsa mgwirizano wathu wopambana.

Nchifukwa chiyani ma valve a mpira wa PVC ndi ovuta kutembenuza?

Mwangotsegula valavu yatsopano m'bokosi ndipo chogwiriracho sichikugwirani ntchito. Mukuyamba kukayikira ngati mwagula chinthu chotsika mtengo chomwe chingakulepheretseni mukachifuna kwambiri.

ChatsopanoMa valve a mpira wa PVCN'zovuta kutembenuza chifukwa cha kukangana pakati pa mipando ya PTFE youma komanso yolekerera kwambiri ndi mpira watsopano wa PVC. Kulimba koyambirira kumeneku kumatsimikizira kuti chisindikizo chabwino kwambiri, chosatulutsa madzi chidzapangidwa.

Ndiloleni ndilowe m'kati mwa njira yopangira, chifukwa izi zikufotokoza zonse. Timapanga ma valve athu a Pntek pa cholinga chimodzi chachikulu: kuletsa madzi kutuluka kwathunthu. Kuti tikwaniritse izi, timagwiritsa ntchito kwambirikulolerana kolimbaZinthu zofunika kwambiri ndi mpira wosalala wa PVC ndi mphete ziwiri zotchedwaMipando ya PTFE. Mutha kudziwa PTFE ndi dzina lake la Teflon. Mukatembenuza chogwirira, mpira umazungulira mipando iyi. Mu valavu yatsopano, malo awa ndi oyera komanso ouma bwino. Kutembenuka koyamba kumafuna mphamvu zambiri chifukwa mukugonjetsa kukangana kosasinthasintha pakati pa zigawo zatsopanozi. Zili ngati kutsegula mtsuko watsopano; kupotoza koyamba nthawi zonse kumakhala kovuta chifukwa kumaswa chisindikizo chabwino. Vavu yomwe imatembenuka mosavuta kuyambira pachiyambi ikhoza kukhala ndi zolekerera zomasuka, zomwe zingayambitse kutuluka pang'onopang'ono pansi pa kupanikizika. Chifukwa chake, kuuma koyambako ndiye umboni wabwino kwambiri wa valavu yopangidwa bwino komanso yodalirika.

Kodi mungadziwe bwanji ngati valavu ya PVC ndi yoyipa?

Valavu yanu sikugwira ntchito bwino. Simukudziwa ngati yangokakamira ndipo ikufunika mphamvu, kapena ngati yasweka mkati ndipo ikufunika kusinthidwa kwathunthu.

Vavu ya PVC ndi yoipa ngati ikutuluka m'chogwirira kapena m'thupi, imalola madzi kudutsa akatsekedwa, kapena ngati chogwiriracho chikutembenuka popanda kuletsa kuyenda kwa madzi. Kuuma kokha si chizindikiro cha kulephera.

Kwa makasitomala a kampani ya Budi, kudziwa kusiyana pakati pa valavu yolimba ndi valavu yoyipa n'kofunika kwambiri popanga chisankho choyenera chokonza. Vavu yoyipa imakhala ndi zizindikiro zomveka bwino za kulephera zomwe zimapitirira kungokhala zovuta kuzitembenuza. Ndikofunikira kuyang'ana zizindikiro izi.

Kuuma kwa valavu yatsopano ndi kwachibadwa. Komabe, ngati valavu yakale yomwe inkazungulira mosavuta yakhala yolimba kwambiri, nthawi zambiri imasonyezakusonkhanitsa mchere mkatiNgakhale kuti si "yoipa" m'lingaliro lakuti yasweka, imasonyeza kuti valavu yatha ntchito ndipo iyenera kukonzedwa kuti isinthidwe.

Kodi mafuta abwino kwambiri opangira ma valve a mpira ndi ati?

Mwachibadwa, mumakuuzani kuti mutenge mafuta opopera kuti mugwiritse ntchito valavu yolimba. Koma mukukayikira, chifukwa choopa kuti mankhwalawo angafooketse pulasitiki kapena kuipitsa madzi.

Mafuta okhawo otetezeka komanso ogwira mtima a ma valve a mpira wa PVC ndi mafuta opangidwa ndi silicone 100%. Musagwiritse ntchito mafuta monga WD-40, chifukwa angapangitse PVC kukhala yopyapyala ndikupangitsa kuti isweke.

Uwu ndi upangiri wofunikira kwambiri wokhudza chitetezo womwe ndingapereke, ndipo ndikutsimikiza kuti bungwe lonse la Budi likumvetsa. Kugwiritsa ntchito mafuta osayenera n'koipa kuposa kugwiritsa ntchito mafuta osadzola konse. Zinthu zodziwika bwino zapakhomo monga WD-40, petroleum jelly, ndi mafuta ogwiritsidwa ntchito nthawi zonse zimakhala zochokera ku mafuta. Mankhwalawa sagwirizana ndi PVC. Amagwira ntchito ngati chosungunulira, pang'onopang'ono akuswa kapangidwe ka mankhwala a pulasitiki. Izi zimapangitsa PVC kukhala yofooka komanso yofooka. Valavu yothiridwa motere ikhoza kusinthasintha mosavuta lero, koma ikhoza kusweka ndikuphulika mawa ikapanikizika. Zipangizo zokha zomwe zili zotetezeka ku thupi la PVC, ma EPDM O-rings, ndi mipando ya PTFE ndiMafuta a silicone 100%Silicone ndi yopanda mankhwala, zomwe zikutanthauza kuti sidzagwirizana ndi kapena kuwononga zinthu za valavu. Pa makina omwe amanyamula madzi akumwa, ndikofunikira kuti mafuta a silicone akhale ndi chiphaso "NSF-61"Kuonetsetsa kuti chakudya chili bwino."

Kodi ma valve a mpira amamatira?

Kwa zaka zambiri simunafunikire kugwiritsa ntchito valavu yozimitsa moto. Tsopano pali vuto ladzidzidzi, koma mukapita kukayitembenuza, chogwiriracho chimakhala chozizira kwambiri, chikukana kusuntha konse.

Inde, ma valve a mpira amamatirira, makamaka ngati sakugwiritsidwa ntchito kwa nthawi yayitali. Zomwe zimayambitsa ndi mchere wochokera ku madzi olimba omwe amalimbitsa mpirawo kapena zisindikizo zamkati zimamatirira.

Izi zimachitika nthawi zonse, ndipo ndi vuto lomwe limabwera chifukwa chosagwira ntchito. Ngati valavu ikhala pamalo amodzi kwa zaka zambiri, makamaka m'dera lomwe lili ndi madzi olimba monga ku Indonesia, zinthu zingapo zimatha kuchitika mkati. Vuto lofala kwambiri ndikusonkhanitsa mchereMadzi ali ndi mchere wosungunuka monga calcium ndi magnesium. Pakapita nthawi, mcherewu ukhoza kukhazikika pamwamba pa mpira ndi mipando, ndikupanga kutumphuka kolimba kofanana ndi konkire. Sikelo iyi imatha kulimbitsa mpirawo pamalo otseguka kapena otsekedwa. Chifukwa china chodziwika bwino ndi kumatira kosavuta. Mipando yofewa ya PTFE imatha kumamatira pang'onopang'ono kapena kumamatira ku mpira wa PVC pakapita nthawi ngati itakanizidwa pamodzi popanda kusuntha. Nthawi zonse ndimauza Budi kuti apereke lingaliro lakuti "kukonza zoletsa"Kwa makasitomala ake. Pa ma valve ofunikira otseka, ayenera kungotembenuza chogwirira kamodzi kapena kawiri pachaka. Kutembenukira mwachangu kumalo otsekedwa ndikubwerera kuti atsegule ndizomwe zimafunika kuti muswe sikelo iliyonse yaying'ono ndikuletsa zisindikizo kuti zisamamatire.
