TWS Backflow Preventor

Njiisyo yakubeleka ya Backflow Preventor

TWS chikwabilila kujokela musulenchibelesyo chakapangwa kuti chilesye kujokela musyule kwamaanzi aasofweede naakuti zimwi zintu munzila yakupa maanzi aakunywa naakuti munzila yamaanzi aasalala, ikusinizya kuti nzila yakusaanguna ilikwabilidwe akusalala. Njiisyo yayo yakubeleka ikapati iyeeme akusanganyamavalvu aakulanga, nzila zyakusiyana kwakusinkilila, mpawo chimwi chiindi mavwili aagwasya kupanga "chisinkilizyo" chakuti maanzi atanjili musule. Aawa mpaapandululwa kabotu-kabotu:

Valve yakulanga yobileNzila
Zyiingi zyazyozikwabilizyo zyakujokela musulebikka mavalvu obile aabeleka aalikke aabikkidwe mumulongo. Ivalvu yakusaanguna yakulanga (inletvvalavu yakulanga) ilazumizya maanzi kuti aunke kuya kunembo muchiimo mubukkale buli kabotu pesi alajala loko kuti kwaba kujokela musule, akulesya kujokela musyule kuzwa kulubazu lwaansi. Wabilivvalavu yakulanga(kuzwidavvalavu yakulanga) ibelekela mbuli chisinkilizyo chachibili: ikuti chakusangunavvalavu yakulangayaalilwa, yabili ilabeleka kuchitila kuti ilesye kujokela musyule, kupa lukwabililo lumbi.

Kulanga-langa kwaandaana kwanguzu
Akati kazeezi zyobilemavalvu aakulanga, kuli busena bwakusiyana kwanguzu (naakuti busena buli akati-kati). Mukubeleka kabotu, nguzu zili kulubazu lwakunjila (kujulu lya valve yakusaanguna) zilisumpukide kwiinda nguzu zili akati-kati, mpawo nguzu zili akati-kati zilisumpukide kwiinda kulubazu lwakuzwa (munsi lya wabilivvalavu yakulanga). Ooku kuchincha kwakusinkilila kupa kuti mavalvu oonse obile azumanane kujaluka, akuzumizya kweenda kuya kunembo.

Kuti kujokela musule kwaswena afwaafwi (nkokuti, akaambo kakuseluka kwachiindi chifwiifwi kwa muya wakujulu naa kutanta kwa muya uuzwa munsi), kweendelana kwa muya kulanyonganizyigwa. Ivalvu yakusaanguna yakulanga ilajalwa kuchitila kutabilila kuzwa kubusena buli akati kuya kumulyango. Ikuti naa vvalavu yabili yakulanga muya uuzwa musule, ilajala kuchitila kuti ilesye kuzwa kulubazu lwakuzwa kuya kubusena buli akati.

Kubelesya Valvu Yakugwasya
Zibelesyo zyiingi zikwabilila maanzi kuti azwe musule zilijisi vvalavu yakugwisya maanzi iiswaangene abusena buli akati. Kuti zyoonse zyobile zyakukwabilila zyaalilwa naakuti kuti muya uuli akati-akati wiinda muya wakunjilila (kutondezya kuti kuli ntenda yakujokela musyule), ivalvu yakugwisya maanzi ilajaluka kuti igwisye maanzi aasofweede aali akati-akati kuya mumulengalenga (naa nzila yakugusya maanzi). Eezi zilesya maanzi aasofweede kuti atapilukili mumaanzi aasalala, akubamba kusyomeka kwanzila yakusaanguna.

Kuchita Zyolikke
Nzila yoonse ilachitika njiyo, taiyandiki kunjililwa amaanza pe. Chibelesyo eechi chilasanduka chakufwambaana kuchincha kwanguzu zyamaanzi anzila njiyakweenda, kuchitila kuti chikwabililwe kuzwa kukujokela musule mubukkale bwiindene-indene bwakubeleka.

Bubotu bwazikwabilizyo zyakujokela musule

Zikwabilizyo zyakujokela musulekuchita mulimu mupati mukukwabilila nzila zyamaanzi, ikapati maanzi aakunka, kwiinda mukulesya kujokela musyule kwamaanzi aasofweede naakuti aatayandiki. Bubotu bwazyo bupati bubikkilizya:

1. **Kukwabilila Bubotu bwamaanzi**

Bubotu butaanzi mbwakukwabilila kusofwaala aakati kanzila zyamaanzi aakunywa azyamaanzi aatakonzyi kunywa (nkokuti, maanzi aasofweede mumafakitali, maanzi aakutilila, naa tombe). Eezi zipa kuti maanzi aakunwa naakuti maanzi aasalala atabi aasofweede, ikucheesya ntenda zyabuumi zijatikizyidwe akunywa maanzi aasofweede.

2. **Kutobelezya milawu**

Muzisi zyiingi, zikwabilizyo zyamaanzi kuti zitanjili musule zilazumizigwa amilawu yamapaipi amilawu yabuumi (mbuli eeyo yakabikkwa ambunga zilimbuli EPA naakuti beendelezi bamaanzi). Kuzibikka kugwasya kuti zibelesyo azibelesyo zizuzikizye ziyandikana amulawu, kutantamuka kubbadelwa mali naakuti kujalwa kwakubeleka.

3. **Kuyungizya aKusyomeka**

Zyiingi zyazyozikwabilizyo zyakujokela musulezilijisi mavwili obile aakulanga-langa alimwi amavwili aakugwasya, akupanga nzila yakukwabilila iitayandiki. Kuti chimwi chibeela chakachilwa, zimwi zilabeleka mbuli zikwabilizyo, ikucheesya ntenda yakujokela musule. Bupange oobu bupa kuti kube kubeleka kabotu nikuba kuti kuli kucinca-cinca kwanguzu naakuti kweenda kwamaanzi.

4. **Kubelesya zintu zyiingi**

Zilakonzya kubelesegwa mumasena aasiyene, mbuli mumaanda aakukkala, mumakwebo, mumafakitali, amumadolopo. Nikuba kuti zibelesyegwa mumapayipi, nzila zyakutilila, naakuti munzila zyamafakitali, zikwabilizyo zyamaanzi kuti zitanjili musule zilakwabilila maanzi kuti atanjili musule kakunyina kulanga musyobo wamaanzi (maanzi, makemikalu, azimwi) naakuti bupati bwamaanzi.

5. **Kucheesya Kunyonyooka Kwazibelesyo**

Kwiinda mukulesya kweenda kwakujokela musule, zikwabilizyo zyakujokela musyule zikwabilila mpompi, maboila, zibelesyo zyakupyasya maanzi, azimwi zibeela zyamunzila kuti zitanyonyooki akaambo kakujokela musule naa nkomo yamaanzi (kutanta kwamaanzi kwakacitika cakutayeeyelwa). Eezi zipa kuti zibelesyo zizumanane kupona kwachiindi chilamfu mpawo zigwisye mali yakuzibamba.

6. **Kuchita Zyolikke**

Zikwabilizyo zyakujokela musulekubeleka kakunyina kugwasyigwa amaanza, kuvwiila mpawo-mpawo kuchincha kwanguzu naakuti kuchincha kwamaanzi. Eezi zipa kuti kube lukwabililo luzumanana kakunyina kusyoma bantu, kupa kuti zibelesyegwe munzila zitakwe bantu naakuti zilikule.

7. **Kubelesya mali manji**

Nikuba kuti mali aakusaanguna aakubikka aliwo, mali yakuyobola kwachiindi chilamfu nchintu chipati. Zicesya mali zibelesyegwa mukusalazya maanzi aasofweede, kubambulula zibelesyo, zisubulo zyamilawu, antoomwe amilandu iikonzya kuchitwa akaambo kazyintu zikonzya kuchitika akaambo kamaanzi aasofweede. Mubwini, zikwabilizyo zyakujokela musyule zilayandika kapati mukubamba kusyomeka kwabweende bwazintu, buumi bwabantu boonse, akubeleka obotu mumilimo myiingi iibelesya maanzi.
