Kodi pompu yanu ikutaya mphamvu yake? Valavu ya phazi lolephera kugwira ntchito imabweretsa kusokonekera kwa makina komanso kuwonongeka kwa pompu kokwera mtengo. Kusankha zinthu zoyenera, monga PVC kapena brass, ndiye chitetezo chanu choyamba.

Pa ntchito zambiri zamadzi, kuthirira, ndi mankhwala, ma valve a mapazi a PVC ndi abwino chifukwa cha kukana dzimbiri komanso mtengo wotsika. Mkuwa ndi wabwino kwambiri pa ntchito zotentha kwambiri, zitsime zakuya, kapena komwe kumafunika kulimba kwambiri kuti zisawonongeke.

Kungosankha zinthu sikokwanira. Oyang'anira bwino kugula zinthu, monga Carlos, amadziwa kuti phindu lenileni lili pakumvetsetsa zabwino ndi zoyipa za njira iliyonse. Pitirizani kuwerenga, chifukwa chidziwitso chozama ichi ndicho chimateteza ndalama zanu komanso chidaliro cha makasitomala anu.

Ndi ma valve ati abwino a mkuwa kapena PVC?

Kodi mwakhala pakati pa mkuwa wachikhalidwe ndi PVC yamakono? Kupanga chisankho cholakwika kungayambitse kulephera kwa makina msanga komanso kusintha zinthu modula. Tiyeni tifotokoze bwino chomwe chili choyenera kwa inu.

Ma valve a PVC ndi abwino kugwiritsa ntchito madzi ozizira, madzi owononga, komanso ndalama zochepa. Ma valve amkuwa ndi abwino kugwiritsa ntchito madzi otentha, mpweya wothamanga kwambiri kapena mpweya, ndipo malamulo a makina amadzi akumwa amafuna zitsulo.

Mu zomwe ndakumana nazo ku Pntek, ndawona makasitomala akusunga ndalama zambiri pa ntchito posintha kuchoka pa mkuwa kupita ku PVC komwe kuli koyenera. Wogulitsa ngati Carlos akhoza kupanga mwayi wopikisana nawo kwambiri potsogolera makasitomala ake ku yankho lotsika mtengo komanso lodalirika, osati lachikhalidwe chokha. Kusankha kumadalira kusiyana kwakukulu.

Katundu wa Zinthu

Mfundo yaikulu ya mkangano ndi zinthu zomwe zili mkati mwake. Mkuwa ndi aloyi wachitsulo, pomwe PVC ndi polima. Izi zimapangitsa kuti pakhale kusiyana kwakukulu pa magwiridwe antchito.PVC siingathe kugwidwa ndi dzimbiri komanso dzimbiri.kuchokera m'madzi ndi mankhwala osiyanasiyana, komwe ndi malo olephera kwambiri a zitsulo. Komabe, mkuwa ukhoza kuthana ndi kutentha kwambiri komanso kupsinjika popanda kupunduka. Mkuwa ndi wolemera kwambiri komanso wopirira kukhudzidwa ndi thupi.

Mtengo ndi Kukhazikitsa

Apa ndi pomwe PVC imaonekera bwino kwa woyang'anira kugula. Ma valve a PVC ndi otsika mtengo kwambiri popanga ndi kugula. Kulemera kwawo kopepuka kumatanthauzanso kuchepetsa mtengo wotumizira ndi kutumiza katundu pa oda iliyonse yomwe Carlos amaika. Kukhazikitsa kumakhala kosavuta komanso kwachangu ndi PVC, nthawi zambiri pogwiritsa ntchito simenti yosungunulira, yomwe imapanga mgwirizano wokhazikika, wosatulutsa madzi. Mkuwa umafuna zolumikizira za ulusi ndi sealant, zomwe zimafuna ntchito yambiri.

Kodi valavu ya phazi yabwino kwambiri ndi iti?

Mukuganiza kuti ma valve onse a mapazi ndi ofanana? Valavu yopangidwa molakwika idzalephera, zomwe zimapangitsa kuti pampu yanu iume ndikutha. Valavu yabwino kwambiri ili ndi zinthu zinazake zomwe muyenera kuziyang'ana.

Mtundu wabwino kwambiri wa valavu ya phazi umaphatikiza thupi lolimba, losawononga ndi makina odalirika otsekera komanso chotsukira chopangidwa bwino. Thupi la PVC lokhala ndi chisindikizo chodzaza ndi kasupe kapena chotchingira rabara nthawi zambiri ndilo chisankho chothandiza kwambiri komanso chokhalitsa pakugwiritsa ntchito madzi.

Valavu ya phazi "yabwino kwambiri"ndi yomwe siikukupangitsani kuganizira za iyo ikayikidwa. Imagwira ntchito yokha. Kwa Carlos, kupeza valavu yodalirika kwambiri ya mapazi kumatanthauza kuti makasitomala sangadandaule kwambiri komanso kumabweretsa mbiri yabwino. Ku Pntek, tikuyang'ana kwambiri mbali zitatu zofunika kwambiri kuti tikwaniritse kudalirika kumeneku.

Njira Yotsekera

Cholinga chonse cha valavu ya phazi ndikusunga madzi mu chingwe chokokera madzi pamene pampu yazimitsidwa. Chisindikizo ndicho chilichonse.

• Yodzaza ndi masika:Izi zimagwiritsa ntchito kasupe kukankhira diski kapena mpira pampando. Zimapereka chisindikizo chabwino kwambiri ndipo zimatha kuyikidwa molunjika kulikonse. Iyi ndi kapangidwe kodalirika kwambiri.
• Wopanga chophimba:Chophimba chosavuta cha rabara kapena pulasitiki chimaphimba potulukira. Mphamvu yokoka ndi kuthamanga kwa madzi zimathandiza kuti chitseke. Ndi chotsika mtengo ndipo chimagwira ntchito bwino koma chiyenera kuyikidwa moyima.
• Mpira:Mpira woyandama womasuka umakhala mu khola ndipo umatseka potulukira madzi akasiya kutuluka. Ndi kapangidwe kosavuta koma nthawi zina umatha kutsekeka ngati pali zinyalala.

Kapangidwe ka Chotsukira (Chophimba)

Chotsekera ndi mzere woyamba wa chitetezo cha valavu, chomwe chimaletsa masamba, miyala, ndi zinyalala zina kulowa ndikuwononga pampu. Chotsekera chabwino chimakhala ndi mabowo ang'onoang'ono okwanira kutseka tinthu towononga koma akuluakulu mokwanira kuti asalepheretse madzi kuyenda bwino, zomwe zingatseke pampu. Timagwiritsa ntchito PVC yolimbikitsidwa pa zotsekera zathu kuti zitsimikizire kuti sizikugwa kapena kuwononga pakapita nthawi.

Kusankha Zinthu Zofunikira pa Ntchito

Monga tafotokozera, zinthu zofunika kwambiri pa thupi la munthu ndi izi. Pa ulimi wothirira, maiwe, ndi njira zambiri zotumizira madzi, PVC ndi yabwino kwambiri. Pa zitsime zakuya komanso zamiyala komwe valavu ingakhudzidwe, kapena pa njira zamadzi akumwa, valavu ya mkuwa yolemera, yopanda lead ingafunike.

Kodi kuipa kwa zolumikizira zamkuwa ndi kotani?

Kodi brass nthawi zonse ndi chisankho chapamwamba komanso chopanda nkhawa? Chikhulupiriro chofalachi chingabise zovuta zazikulu zomwe zimakhudza phindu lanu. Kumvetsetsa zovuta izi ndikofunikira kwambiri pogula zinthu mwanzeru.

Zoyipa zazikulu za mkuwa ndi mtengo wake wokwera, kulemera kwake kwakukulu komwe kumawonjezera ndalama zotumizira, komanso kufooka kwake ku mtundu wina wa dzimbiri wotchedwa dezincification, makamaka m'madzi okhala ndi chlorine wambiri kapena pH yotsika. Ma alloy ena a mkuwa alinso ndi lead.

Nthawi zonse ndimalimbikitsa ogula ngati Carlos kuti aziganizira mtengo wonse wa umwini, osati mtengo woyambirira wokha. Ngakhale kuti brass imawoneka yayikulu, zofooka zake zingayambitse mavuto a nthawi yayitali omwe zinthu monga PVC sizili nazo. Nkhani yake ndi kusankha chida choyenera pantchitoyo.

Kuwononga Zinc ndi Kuukira kwa Mankhwala

Mkuwa ndi chinthu chopangidwa ndi mkuwa ndi zinc. M'madzi ena, zinc imatha kuchotsedwa mosavuta kuchokera pamalo olumikizirana, ndikusiya kapangidwe ka mkuwa kofooka, kokhala ndi mabowo komwe kamakhala ndi ming'alu komanso kulephera. Izi zimatchedwakuchotsedwa kwa zinkiNdi chinthu chopha madzi pang'ono. Zopangira zopangidwa ndi PVC yabwino sizimakhudzidwa ndi zinthu zimenezi, zomwe zimapangitsa kuti zikhale zodziwikiratu komanso zamoyo nthawi yayitali m'madzi osiyanasiyana.

Mtengo Weniweni: Mtengo ndi Kulemera

Kwa woyang'anira kugula, bajeti ndiye chinthu chofunika kwambiri. Zomangira za mkuwa nthawi zonse zimakhala zodula kuposa za PVC, nthawi zambiri zimakhala ndi phindu lalikulu. Koma mtengo wake suthera pamenepo. Mkuwa ndi wokhuthala kasanu ndi katatu kuposa PVC. Izi zikutanthauza kuti kutumiza kulikonse kwa ma valve ndi zomangira zamkuwa kumawononga ndalama zambiri mu katundu. Pakatha chaka chimodzi, izi zimapangitsa kuti pakhale ndalama zambiri zomwe zimakhudza mwachindunji bajeti ya Carlos ndi phindu la kampaniyo.
