II Kirazira makumyabiri na gatanu kubicuruzwa byumye byashyizweho, uzi bangahe?

Taboo 11 Uburyo bwo gushiraho valve nabi. Kurugero, icyerekezo cyamazi (parike) cyerekezo cyo guhagarara valve cyangwa kugenzura valve bihabanye nikimenyetso, uruti rwa valve rwashyizwe hepfo, igenzura rya valve ryashyizwe kuri horizontalale ryashyizwe muburyo buhagaritse, ikiganza cyizamuka ryurugi rwibiti cyangwa ikinyugunyugu ntigifite umwanya wo gufungura no gufunga, na valve stem ya valve ihishe ntabwo ihura na valve yo kugenzura. Ingaruka: kunanirwa na valve, guhindura ingorane zo kubungabunga, guhagarara akenshi bitera amazi kumeneka. Ingamba: shyiramo ukurikije amabwiriza yo kwishyiriraho valve. Irembo ryizamuka rya valve rigomba kugira uburebure bwagutse bwo gufungura uburebure. Umwanya wo kuzunguruka ugomba gufatwa neza kuri kinyugunyugu. Igiti cyimyanya itandukanye ntigomba kuba munsi yumwanya utambitse cyangwa hepfo. Umuyoboro uhishe ntushobora gusa guhabwa igenzura ryujuje ibyangombwa byo gufungura no gufunga ibisabwa, ariko kandi uruti rwa valve rugomba guhura na valve. Taboo 12 Ibisobanuro na moderi ya valve yashyizweho ntabwo yujuje ibyashizweho. Kurugero, igitutu cyizina cya valve kiri munsi yikigereranyo cya sisitemu; iyo umuyoboro wa diameter wumuyoboro wamazi utanga amazi ari munsi cyangwa ingana na mm 50, ikoreshwa rya valve; guhagarara guhagarara bikoreshwa mumiyoboro yumye kandi ihagaritse yo gushyushya amazi ashyushye; ikinyugunyugu gikoreshwa mu miyoboro yo gukuramo amazi ya pompe yumuriro. Ingaruka: bigira ingaruka kumugaragaro no gufunga valve hanyuma uhindure guhangana, igitutu nibindi bikorwa. Ndetse utera imikorere ya sisitemu, ibyangiritse byangiritse gusanwa. Ibipimo: menyera urwego rushyirwa mubikorwa bya valve zitandukanye, hanyuma uhitemo ibisobanuro na moderi ya valve ukurikije ibisabwa. Umuvuduko wizina wa valve ugomba kuba wujuje ibisabwa byumuvuduko wikizamini. Ukurikije ibisabwa byubwubatsi: guhagarika valve bizakoreshwa mugihe diameter yumuyoboro wogutanga amazi ari munsi cyangwa ingana na 50mm; irembo rya valve rizakoreshwa mugihe diameter irenze 50mm. Irembo ry'irembo rigomba gukoreshwa mu gushyushya amazi ashyushye yumye kandi ihagaritse kugenzura, kandi ikinyugunyugu ntigishobora gukoreshwa mu muyoboro wo kuvoma pompe. Taboo 13 Mbere yo gushiraho valve, ubugenzuzi bukenewe ntibukorwa nkuko bisabwa. Ingaruka: mugihe cya sisitemu, imikorere ya valve ntabwo ihinduka, gufunga ntabwo bikomeye kandi ikibazo cyo kumeneka kwamazi (parike) kibaho, bigatera gukora no gusana, ndetse bikagira ingaruka kumazi asanzwe (parike). Ibipimo: imbaraga zumuvuduko nigeragezwa bizakorwa mbere yo gushiraho valve. 10% ya buri cyiciro (cyikimenyetso kimwe, ibisobanuro hamwe nicyitegererezo) bizatoranywa kubizamini, kandi bitari munsi yimwe. Kugirango ibyuma bifunze-byumuzunguruko byashyizwe kumuyoboro munini kugirango ucike, imbaraga nimbaraga zo kugerageza bizakorwa umwe umwe. Imbaraga za valve hamwe nigitutu cyikizamini kigomba kubahiriza ibiteganywa nigitabo cyo kwemeza ireme ryubwubatsi bwogutanga amazi nogutwara amazi nubushyuhe (GB 50242-2002). Taboo 14 Ibikoresho byingenzi, ibikoresho nibicuruzwa bikoreshwa mubwubatsi ni ukubura ibyangombwa biranga ubuhanga bwa tekiniki cyangwa ibyemezo byibicuruzwa byujuje ubuziranenge butangwa na leta cyangwa Minisiteri. Ingaruka: ubuziranenge bwumushinga ntabwo bujuje ibisabwa, hashobora kubaho impanuka, kandi ntishobora gutangwa no gukoreshwa ku gihe, igomba rero kongera gukorwa no gusanwa; igihe cyo kubaka kiratinda, kandi kwinjiza imirimo nibikoresho byiyongera. Ingamba: ibikoresho by'ibanze, ibikoresho n'ibicuruzwa bikoreshwa mu gutanga amazi no kuhira amazi, gushyushya no gukora isuku bigomba guhabwa ibyangombwa byo gusuzuma ubuziranenge bwa tekiniki cyangwa ibyemezo by'ibicuruzwa byujuje ubuziranenge butangwa na Leta cyangwa Minisiteri; izina ryibicuruzwa, icyitegererezo, ibisobanuro, code yubuziranenge bwigihugu, itariki yo kugemura, izina ryuwabikoze n’aho biherereye, icyemezo cyo kugenzura ibicuruzwa cyangwa kode igomba kwerekanwa. Taboo 15 Inversion Inversion Ingaruka: kugenzura valve, valve ya trottle, umuvuduko ugabanya valve, kugenzura valve nibindi byerekezo. Niba zashyizwe muburyo butandukanye, trottle valve izagira ingaruka kubikorwa bya serivisi nubuzima; umuvuduko ugabanya valve ntabwo uzakora na gato, kandi cheque ya valve niyo izatera akaga. Ibipimo: kubisanzwe muri rusange, hari ikimenyetso cyerekezo kumubiri wa valve; niba atari byo, bigomba kumenyekana neza ukurikije ihame ryakazi rya valve. Umuyoboro wa valve wo guhagarara ntushobora guhuza. Amazi agomba kwemererwa kunyura ku cyambu cya valve kuva hasi kugeza hejuru, kugirango irwanya amazi iba nto (bigenwa nuburyo), gufungura ni ugukoresha imirimo (kubera umuvuduko wo hejuru wikigereranyo), hamwe nuburyo bwo hagati ntabwo ihatirwa nyuma yo gufunga, byoroshye kubungabunga. Ninimpamvu ituma guhagarara guhagarara bidashobora guhinduka. Ntugashyireho amarembo ya ruguru hejuru (nukuvuga uruziga rwamaboko rumanuka), bitabaye ibyo, uburyo buzaguma mumwanya wo gutwikira valve umwanya muremure, byoroshye korora igiti cya valve, kandi birabujijwe nibisabwa mubikorwa. Igihe kimwe, ntibyoroshye guhindura ibipaki. Gufungura amarembo yumudugudu ntushobora gushyirwaho munsi yubutaka, bitabaye ibyo uruti rugaragara ruzangirika kubera ubushuhe. Mugihe ushyiraho lift igenzura, reba neza ko disiki ya valve ihagaritse, kugirango lift ihinduke. Igenzura rya swing rigomba gushyirwaho na pin shaft itambitse kugirango rishobore guhindagurika. Umuvuduko wubutabazi wumuvuduko ugomba gushyirwaho uhagaritse kumuyoboro utambitse kandi ntushobora guhinduka muburyo bwose.
