Zamgulu Mbali
1) Mogwirizana ndi miyezo ya madzi akumwa.
2) Zinthuzo zimasinthidwa ndi nano kuti zithandizire kukana kwazinthu komanso kukana kwamphamvu.
3) Kuonjezera ma anti UV absorbers ndi ma antioxidants kuzinthu zopangira kuti apititse patsogolo kukana kwa nyengo ndi kukalamba.
4) Ikhoza kukhazikitsidwa molunjika kapena molunjika.
PVC woona mgwirizano cheke vavu mankhwala ndi asidi, zamchere, ndi mkulu-kutentha kugonjetsedwa, chimagwiritsidwa ntchito m'mafakitale osiyanasiyana monga makampani mankhwala, mankhwala amadzi otayira, zomangamanga zomera, PCB kupanga mzere, asidi heavy ndi alkali makampani, ndi madzi kuyeretsa zomangamanga.
Chigawo chatsopano cha njanji chokhala ndi njanji yowongolera chimatsimikizira kuti dziko lapansi silimapendekeka ndipo lili ndi mphamvu yoyimitsa madzi.
Magawo olumikizira mbali zonse za mankhwalawa amapangidwa mu mawonekedwe olumikizana osinthika, omwe ndi abwino kuyika ndikusintha.
Mankhwalawa ndi pulasitiki kwathunthu popanda zowonjezera zitsulo.
Kodi valavu ya cheki imagwira ntchito bwanji?
1. Pewani sing'angayo kuti isabwerere chammbuyo
Vavu yoyang'ana ili ndi njira imodzi yokha yolowera, ndiko kuti, motsatira njira yolowera, kuti madzi asayendere mbali ina. Sing'anga yoyenda kuchokera kumbali yolowera (mbali yakumunsi) kupita, kuchokera kumbali yotulukira (kumtunda) kunja. Pamene kulowetsedwa kolowera kumakhala kwakukulu kuposa kulemera kwa valve ndi kukana kwake kothamanga komanso pamene valve imatsegulidwa. Mosiyana ndi zimenezi, pamene sing'anga imayenda chammbuyo, valavu imatsekedwa.
2. Pewani mpope ndi kuyendetsa galimoto kuti zisabwerere
Chongani valavu ndi ntchito yodziwikiratu, komwe kumayendera kuthamanga kwamadzimadzi, valavu yotseguka; madzimadzi amapita mbali ina, ndi kuthamanga kwamadzimadzi ndi valavu yamadzimadzi ya valavu yamadzimadzi imagwira pampando wa valve, motero imadula kutuluka.
3. Pewani kutayikira kwa chidebe chapakati
Ma valve owunikira angagwiritsidwe ntchito kuti apereke kupanikizika kungathe kupitilira kukakamiza kwapaipi yothandizira pamapaipi othandizira. Amagwiritsidwa ntchito m'mapaipi pomwe sing'anga imayenda mbali imodzi, kulola sing'anga kuyenda mbali imodzi yokha kuti ateteze ngozi.
Kodi chimachitika ndi chiyani popanda valavu?
1) Mapampu amadzi opanda ma valve owunika angayambitse mapaipi amadzi kuphulika
Mapampu amadzi samayikidwa valavu yowunikira, pompayo ikasiya kugwira ntchito, madzi otaya amabwerera m'mbuyo, ndipo mapaipi ena amakhala osasunthika, alibe ntchito yobwerera, pakadali pano kubweza kwamadzi kudzapanga kukakamiza, kuonjezera kuthamanga kwa madzi. payipi, ndipo mwinanso kuphulitsa chitoliro cha madzi, kubweretsa mavuto osafunikira ndi kutayika kwa alendi.
2) Pampuyo ilibe zida zoyendera zingayambitse kuipitsidwa kwa reflux
Mapampu amadzi alibe zida zowunikira, pompayo ikugwira ntchito, kuyenda kwamadzi kumatha kukhala koyenda bwino, koma pompayo ikasiya kugwira ntchito kapena kusayenda bwino, mpope sungathe kutsimikizira njira imodzi yamadzi. Pamenepa, chimbudzicho chidzabwereranso m’mipope yamadzi aukhondo, zomwe zidzadzetsa kuipitsa kwa madzi ndi kuika chiwopsezo ku thanzi la eni nyumba. Pa nthawi yomweyi, chifukwa cha kulowa kwa madzi obwerera m'mbuyo, zidzachititsanso kudzikundikira kwa matope mu chitoliro, zomwe zimakhudza moyo wa ntchito ya chitoliro cha madzi.
3) Pampu sichiyika valavu yoyendera idzawononga mphamvu
Mapampu amadzi omwe sanayikidwe valavu amatanthawuza kuti pakukhazikitsa njirayo idzawononga mphamvu zambiri, kulepheretsa madzi oyenda unidirectional, kufunikira kosalekeza kuwononga mphamvu kuti ayende, kuwononga magetsi osafunika.
Pofuna kupewa zoopsa zomwe tazitchula pamwambapa, tiyenera kuonetsetsa kuti poika mpope wa madzi, tiyenera kuyang'ana ngati valve yowunikira yayikidwa kapena ayi, kuti tiwonetsetse kuti kutuluka kwa madzi sikudzabwerera m'mbuyo ndikuyambitsa kugwirizana. mavuto.
