Muyenera kuwongolera kuyenda kwa madzi mu njira yatsopano yopayikira mapaipi. Mukuwona "PVC ball valve" pamndandanda wa zida, koma ngati simukudziwa kuti ndi chiyani, simungatsimikize kuti ndi chisankho choyenera pantchitoyo.

Vavu ya mpira wa PVC ndi valavu yolimba yapulasitiki yotseka yomwe imagwiritsa ntchito mpira wozungulira wokhala ndi dzenje mkati mwake kuti ilamulire kuyenda kwa madzi. Yopangidwa kuchokera ku Polyvinyl Chloride, ndi yotsika mtengo komanso yolimba ku dzimbiri ndi dzimbiri.

Ichi ndi chinthu choyamba chomwe ndidayambitsa kwa anzanga atsopano monga Budi ku Indonesia.Valavu ya mpira wa PVCndiye maziko a zamakonokasamalidwe ka madziNdi yosavuta, yodalirika, komanso yosinthasintha kwambiri. Kwa woyang'anira zogula ngati Budi, kumvetsetsa bwino za chinthu chachikuluchi ndikofunikira. Sikuti kungogula ndi kugulitsa gawo lake kokha; koma kupatsa makasitomala ake yankho lodalirika la chilichonse kuyambirakuthirira kunyumbaKupita ku mapulojekiti akuluakulu a mafakitale. Mgwirizano wopindulitsa aliyense umayamba ndi kuphunzira bwino zoyambira pamodzi.

Kodi cholinga cha valavu ya mpira wa PVC ndi chiyani?

Muli ndi payipi ndipo muyenera kulamulira zomwe zimayendamo. Popanda njira yodalirika yoletsera kuyenda kwa madzi, kukonza kapena kukonza kulikonse kudzakhala chisokonezo chachikulu.

Cholinga chachikulu cha valavu ya mpira wa PVC ndikupereka mphamvu yoyatsa/kuzima mwachangu komanso mokwanira mu dongosolo lamadzimadzi. Kutembenuza chogwirira mwachangu kotala limodzi kumatha kuyimitsa kwathunthu kapena kulola kuti chiziyenda bwino.

Taganizirani izi ngati choyatsira madzi. Ntchito yake yayikulu sikuwongolera kuchuluka kwa madzi, koma kuyambitsa kapena kuyimitsa madzi mwachangu. Ntchitoyi ndi yofunika kwambiri pa ntchito zambirimbiri. Mwachitsanzo, makasitomala a Budi amagwiritsa ntchito izi kupatula magawo a makina opopera madzi. Ngati chipangizo chimodzi chikufunika kukonzedwa, amatha kutseka madzi kupita kudera laling'onolo m'malo mwa nyumba yonse. Mu ulimi wothirira, amagwiritsa ntchito izi kutsogolera madzi kupita kumadera osiyanasiyana. M'madziwe ndi m'malo osambira, amayang'anira madzi kupita ku mapampu, zosefera, ndi zotenthetsera. Kuchita kosavuta komanso kwachangu kwavalavu ya mpiraIzi zimapangitsa kuti ikhale chida chofunikira kwambiri popereka chitetezo chabwino, kuonetsetsa kuti dongosolo lonse lili ndi chitetezo komanso kulamulira. Ku Pntek, timapanga ma valve athu kuti asindikize bwino, kotero akatsekedwa, amakhalabe otsekedwa.

Kodi mpira wa PVC umatanthauza chiyani?

Mukamva mawu oti “mpira wa PVC” ndipo amamveka ngati ang'onoang'ono kapena osokoneza. Mungaganize kuti akutanthauza gawo lina, zomwe zimapangitsa kuti zikhale zovuta kumvetsetsa malondawo ndikuyitanitsa molondola.

"Mpira wa PVC" umafotokoza mbali ziwiri zazikulu za valavu yokha. "PVC" ndi chinthu, Polyvinyl Chloride, chomwe chimagwiritsidwa ntchito pa thupi. "Mpira" ndi chozungulira chomwe chimatseka kuyenda kwa madzi.

Tiyeni tifotokoze dzinali, monga momwe ndimachitira nthawi zambiri kwa ogulitsa atsopano a Budi. Sizovuta monga momwe zimamvekera.

• PVC (Polyvinyl Chloride):Uwu ndi mtundu weniweni wa pulasitiki wolimba komanso wolimba womwe thupi la valavu limapangidwa nawo. Timagwiritsa ntchito PVC chifukwa ndi chinthu chabwino kwambiri chogwiritsira ntchito madzi. Ndi chopepuka, chomwe chimapangitsa kuti chikhale chosavuta kugwiritsa ntchito ndikuyika. Chimalimbananso ndi dzimbiri komanso dzimbiri, mosiyana ndi mavalavu achitsulo omwe amatha kuwonongeka pakapita nthawi, makamaka ndi mankhwala enaake kapena madzi olimba. Pomaliza, ndi yotsika mtengo kwambiri.
• Mpira:Izi zikutanthauza makina omwe ali mkati mwa valavu. Ndi chibowo chokhala ndi dzenje (doko) lobooledwa molunjika. Vavu ikatsegulidwa, dzenjelo limalumikizana ndi chitoliro. Mukatembenuza chogwirira, mpirawo umazungulira madigiri 90, ndipo mbali yolimba ya mpirawo imatseka chitolirocho.

Chifukwa chake, "valavu ya mpira wa PVC" imangotanthauza valavu yopangidwa ndi zinthu za PVC yomwe imagwiritsa ntchito njira ya mpira.

Ndi ma valve ati abwino a mkuwa kapena PVC?

Mukusankha pakati pa mkuwa ndi PVC pa ntchito. Kusankha zinthu zolakwika kungayambitse kulephera msanga, kuwononga ndalama zambiri, kapena kuipitsa mbiri yanu.

Palibe chabwino kuposa ichi; ndi cha ntchito zosiyanasiyana. PVC ndi yabwino kwambiri pa ntchito zamadzi ozizira, mankhwala, komanso ntchito zotsika mtengo chifukwa ndi yolimba pa dzimbiri komanso yotsika mtengo. Mkuwa ndi wabwino kwambiri pa kutentha kwambiri komanso kupsinjika.

Funso ili ndi lofala kwambiri kwa makasitomala a Budi, ndipo yankho lolondola limasonyeza ukatswiri weniweni. Kusankha kumadalira kwathunthu zosowa za pulogalamuyo. Nthawi zonse ndimalangiza kugwiritsa ntchito tebulo losavuta loyerekeza kuti chisankhocho chimveke bwino.

Pa ntchito zambiri zosamalira madzi, PVC imapereka magwiridwe antchito abwino kwambiri komanso phindu.

Kodi cholinga cha valavu ya PVC ndi chiyani?

Mumawona valavu ya PVC ngati chinthu chimodzi chokha. Kuwona pang'ono kumeneku kungakupangitseni kuphonya chithunzi chachikulu cha chifukwa chake kugwiritsa ntchito PVC mu dongosolo lonse ndi chisankho chanzeru.

Cholinga cha valavu ya PVC ndikulamulira kuyenda kwa madzi pogwiritsa ntchito chinthu chotsika mtengo, chopepuka, komanso chosagonjetsedwa ndi dzimbiri. Imapereka yankho lodalirika komanso lokhalitsa popanda kuwononga chitsulo kapena mankhwala.

Ngakhale ntchito ya valavu imodzi ndikuletsa madzi, cholinga chosankhaPVCpakuti valavu imeneyo ndi chisankho chanzeru pa dongosolo lonse. Pamene polojekiti ikugwiritsa ntchito mapaipi a PVC, kuwagwirizanitsa ndi mavavu a PVC ndiye chisankho chanzeru kwambiri. Kumapanga dongosolo lopanda msoko komanso lofanana. Mumagwiritsa ntchito simenti yosungunulira yomweyi pa maulumikizidwe onse, zomwe zimapangitsa kuti kukhazikitsa kukhale kosavuta komanso kuchepetsa mwayi wolakwika. Mumachotsa chiopsezo chadzimbiri la galvanic, zomwe zingachitike mukalumikiza mitundu yosiyanasiyana ya zitsulo mu payipi. Kwa Budi monga wogulitsa, kusunga makina a mapaipi a PVC, zolumikizira, ndi ma valve athu a Pntek kumatanthauza kuti akhoza kupatsa makasitomala ake yankho lathunthu komanso logwirizana. Sikuti kungogulitsa valavu yokha; koma kumapereka zida zake kuti zikhale ndi njira yodalirika, yotsika mtengo, komanso yokhalitsa.
