Mu 'musyokwe wabutale' wamapaipi aamakkampani,mavalvubeleka mbuli babelesi bamaanzi batakwe jwi, kweendelezya kweenda kwamaanzi. Nokuba boobo, chiindi chiingi 'bafwa kabachili baniini,' eecho nchintu chipa kuusa ncobeni. Nikuba kuti tuli mukabunga komwe, nkamboonzi bamwimavalvukuleka mulimu kakuchili chiindi bamwi nibazumanana kubeleka? Mazubaano, atutobele syaazibwene mukweendelezya maanzi Waters kuti tujane kasimpe kabuumi bufwaafwi bwamavalvu.
Zintu zyotatwe zipati zipa kutivvalavu"buumi bufwaafwi"
Kufwundilila Kusikila Kufwa: Kulwana Kwabili Kwakuyuma Kwanguzu Akubola Kuyuma Kupati: Eelyo nguzu zyamunzila noziinda aawo mpozigolela vvalavu,vvalavumubili azisinkilizyo zilasinikizyigwa kapati, mpawo eezi zipa kuti zikwabilizyo zitabeleki kabotu. Kuuma kwa nkomo yamaanzi kwakufwambaana kulimbuli kulichisa mukati, kulakonzya kupa kuti vvalavu itabelesyegwi. Kubola: Mubukkale bukatazya mbuli bwamakemikalu amumaanzi aalwizi, zintu zibola zibeleka mbuli zifuwa ziteteete, akumana kakunyina kwaambuula bupati bwabwaanda bwamubili wavalvu (amweelwe wakubola uuyinda 0.5 mm/mwaka), akumana manguzu, mpawo akupa kuti kube kubola akuzwa. Waters ulamvwisisisya kuti zibelesyo zilayandikana loko, mpawo mavalvu aakwe aasalala (mbuli Hastelloy a duplex steel) alimbuli 'zikwabilizyo zyangolida, 'zisumpula kapati kusinikizyigwa akukazya kubola. Kubeleka loko: Kugela kakunyina luzyalo aamaanzi aafwambaana kapati Kubola: Zibeela ziyumu (mbuli busi bwamabwe aamulota) naa maanzi aafwambaana (mbuli busi alimwi amaanzi aajisi nsinga) zilazumanana kusanzya busena bwakujala alimwi abwaanda bwavalvu, kazibeleka mbuli zipeni zitabaliki zyakuzekaula. Mukuya kwachiindi, eezi zichitwa zipa kuti kube mikooko milamfwu aawo mpokujala, mpawo eezi zipa kuti kujala kutabeleki kabotu. Maanzi aa Waters' aayumu kapati aakujala (mbuli tungsten carbide a STL) antoomwe anzila zyamaanzi zibeleka kabotu zibeleka mbuli 'mabbaaji aabutale' kulwana 'kugonkwa kwazyuulu' ooku kutamani.
Kusinkililwa kwa Asphyxia: kusinkililwa kwakujaya kwabusofwaazi antoomwe azilonda
Kunjila kwabusofwaazi: Bulongo bwakuwelda, nsimbi, azintu zimbi zilakonzya kunjila mumupaipi mpawo zijatikizyidwe aakati kachibbula cha valve amukati. Eezi zilakonzya kupa kuti vvalavu ileke kujala naakuti kujalula kabotu, mpawo muzyiindi zikatazya, zilakonzya kunyonganya busena bwakujala kabotu. Kusanduka kwamabwe aakati-akati akukomena: Mubukkale bumwi (mbuli maanzi aatontola naa bulongo), akati-kati kulakonzya kuba mabwe naa kuvwula mukati kavvalavu, kujala kabotu zijatikizyo zya valve, akusololela kukujala kwakufwambaana naa kujala koonse. Maanzi 'aakwabilila kuzwa kukujala, mbuli mavwili mapati aa V-type ball valve antoomwe azibelesyo zyakukwasula, zibeleka mbuli zibelesyo zigwasya kugwisya 'zibulo zyagazi.'
"Kulubizya" kwasikubelesya kwakafwambaanya buumi bwavalvu
Kweelana aTWS Valve yakujala maanzi, buumi bulamfwu bwavalvu tabuli ntenda pe, pesi mbubambe bwakupanga zintu, kusala zintu, kupanga akubelesya:
Kweezyanisya kubotu, kweendelana azintu ziliwo: Chita buvwuntauzi buzulide bwabukkale bwakubeleka (kusinikizya, kupya, akati-kati, tuniini tuniini, antoomwe akubeleka) kuchitila kuti usale musyobo mubotu wa valve (vvalavu yamulyango, vvalavu ya globe, vvalavu ya bbola,valve ya butterfly) azibelesyo. Zibeela Zipati, Kusoleka Kulondoka: Zyakujala zyobile zyakabambwa kuzwa kuzintu ziyumu zitanyonyooki alimwi zitanyonyooki; chisiko cha valve chakapangwa kuzwa kuzintu ziyumu zitakonzyi kubola antoomwe akubamba kabotu atala; zibeela zipati zyeendelezya manguzu zilasinizyigwa kwiinda mukulanga-langa zintu zitamani (FEA). Busongo, Kulanganya Bubotu: Kuchita zintu munzila iiluzi kupa kuti kube kweendelana, mpawo kulingaula kutali kunyonyoona (RT/UT/PT) kugwisya tumpenda twamukati; kufumbwa nzila nkulipeda kukusyomeka. Kusala Kwabusongo, Kulangila Kumbele: Kopa busolozi bwakusala kwabasyaazibwene anzila zipangidwe kabotu kuchitila kuti mavalvu 'azyalwe muchiindi cheelede, mubusena bweelede.'
Kobamba kabotu "moyo wamakwebo" woonse
Kulezya kwamavalvu kakutanasika chiindi nchitondezyo chakuchenjezya kuti kuli mapenzi aakonzya kuchitika mubweende bwazintu mpawo chitondezya kusweekelwa kwazibelesyo akubeleka obotu. Mukusala Waters, ulikusala kuba aluzibo akulipeda kubikka manguzu mumubili wako. Tatupi buyo zintu zitamani pesi tusumpula zyeelelo zyabweendelezi bwasayaansi akubeleka kweendelana. Lilikke kwiinda mukumvwisisisya, kulemeka, akubalanganya kabotu aaba 'basikwabilizi bamakwebo' batakwe majwi mbabakonzya kubeleka kabotu, kabotu, alimwi kwachiindi chilamfu mumilimo yabo, antoomwe akusinizya kuti nzila zyamakwebo zyeenda kabotu!
