II Ama-taboos angamashumi amabili nanhlanu okufakwa kwe-valve yezimpahla ezomile, wazi kangakanani?

I-Taboo 11 Indlela yokufaka i-valve engalungile. Isibonelo, indlela yokugeleza kwamanzi (i-steam) ye-valve yokumisa noma i-valve yokuhlola iphambene nophawu, isiqu se-valve sifakwe phansi, i-valve yokuhlola efakwe ngokuvundlile ifakwe iqonde phezulu, isibambo se-valve yesango elikhuphukayo noma i-valve butterfly ayinayo. isikhala sokuvula nokuvala, futhi isiqu se-valve ye-valve efihliwe ayibhekani ne-valve yokuhlola. Umphumela: ukwehluleka kwe-valve, ukushintshwa kwezinkinga zokulungisa, ukwehla kuvame ukubangela ukuvuza kwamanzi. Izinyathelo: faka ngokuhambisana ngokuqinile nemiyalelo yokufaka i-valve. I-valve yesango le-stem ekhuphukayo izoba nobude obanele bokuvuleka kwesiqu. Isikhala sokuzungezisa isibambo sizocatshangelwa ngokugcwele iveluve uvemvane. Isiqu samavalvu ahlukahlukene akufanele sibe ngaphansi kunendawo evundlile noma siye phansi. I-valve efihliwe ngeke inikezwe kuphela i-valve yokuhlola ehlangabezana nezidingo zokuvula nokuvala ze-valve, kodwa futhi isiqu se-valve sizobhekana ne-valve yokuhlola. I-Taboo 12 Ukucaciswa kanye nemodeli ye-valve efakiwe akuhlangabezani nezidingo zokuklama. Isibonelo, ingcindezi ebizwa ngokuthi i-valve ingaphansi kwengcindezi yokuhlola uhlelo; lapho ububanzi bepayipi lepayipi legatsha lokuhlinzeka ngamanzi lingaphansi noma lilingana no-50 mm, i-valve yesango isetshenziswa; i-valve yokumisa isetshenziselwa amapayipi omile futhi aqondile okushisa kwamanzi ashisayo; i-butterfly valve isetshenziselwa ipayipi lokudonsa amanzi lepompo lomlilo. Umphumela: kuthinta ukuvulwa nokuvala okuvamile kwe-valve futhi ulungise ukumelana, ukucindezela neminye imisebenzi. Ngisho kubangele ukusebenza kwesistimu, ukulimala kwe-valve okuphoqelelwe ukulungisa. Izinyathelo: Yazi ububanzi bokusebenza kwamavalvu ahlukahlukene, bese ukhetha imininingwane namamodeli wamavalvu ngokuya ngezidingo zokuklama. Ukucindezela okulinganiselwe kwe-valve kuzohlangabezana nezidingo zokucindezela kokuhlolwa kwesistimu. Ngokwezidingo zokucaciswa kokwakhiwa: i-valve yokumisa izosetshenziswa lapho ububanzi bepayipi legatsha lokuhlinzeka ngamanzi lingaphansi noma lilingana no-50mm; I-valve yesango izosetshenziswa uma ububanzi bukhulu kuno-50mm. Ivalvu yesango izosetshenziselwa ukushisisa amanzi ashisayo ivelufa yokulawula eyomile neqondile, futhi ivalve uvemvane ngeke isetshenziselwe ipayipi lokumunca iphampu yomlilo. I-Taboo 13 Ngaphambi kokufakwa kwe-valve, ukuhlolwa kwekhwalithi okudingekayo akwenziwa njengoba kudingekile. Umphumela: ngesikhathi sokusebenza kwesistimu, ukushintshwa kwe-valve akuguquki, ukuvala akuqinile futhi kwenzeka ukuvuza kwamanzi (umusi) okubangela ukuvuselelwa nokulungiswa, ngisho nokuthinta ukunikezwa kwamanzi okujwayelekile (umusi). Izinyathelo: amandla okucindezela kanye nokuhlolwa kokuqina kuzokwenziwa ngaphambi kokufakwa kwe-valve. U-10% weqoqo ngalinye (lomkhiqizo ofanayo, ukucaciswa kanye nemodeli) uzokhethelwa ukuhlolwa, futhi kungabi ngaphansi kweyodwa. Ukuze ama-valve avaliwe afakwe epayipini elikhulu ukuze anqanyulwe, ukuhlolwa kwamandla nokuqina kuzokwenziwa ngamunye ngamunye. Amandla e-valve nokucindezela kokuhlolwa kokuqina kuzohambisana nezinhlinzeko zekhodi yokwamukela ikhwalithi yokwakha yokuphakelwa kwamanzi okwakha kanye ne-drainage kanye nobunjiniyela bokushisisa (GB 50242-2002). I-Taboo 14 Izinto ezisetshenziswayo ezibalulekile, okokusebenza kanye nemikhiqizo esetshenziswa ekwakhiweni ukushoda kwemibhalo yezimpawu zekhwalithi yobuchwepheshe noma izitifiketi zomkhiqizo ezihlangabezana namazinga amanje akhishwe umbuso noma uMnyango. Umphumela: ikhwalithi yephrojekthi ayifanelekile, kunezingozi ezingase zibe khona, futhi ayikwazi ukulethwa futhi isetshenziswe ngesikhathi, ngakho-ke kufanele isetshenziswe kabusha futhi ilungiswe; isikhathi sokwakha sibambezelekile, futhi okokufaka komsebenzi kanye nezinto zokwakha kwanda. Izinyathelo: izinto ezibalulekile, okokusebenza kanye nemikhiqizo esetshenziswa ekuhlinzekeni kwamanzi kanye nokukhipha amanzi kanye nobunjiniyela bokushisisa nokuthuthwa kwendle kuzohlinzekwa ngemibhalo yokuhlolwa kwekhwalithi yobuchwepheshe noma izitifiketi zomkhiqizo ezihlangabezana namazinga amanje akhishwe umbuso noma uMnyango; igama lomkhiqizo, imodeli, ukucaciswa, ikhodi evamile yekhwalithi kazwelonke, usuku lokulethwa, igama lomkhiqizi nendawo, isitifiketi sokuhlolwa komkhiqizo wokulethwa noma ikhodi izokhonjiswa. I-Taboo 15 I-valve inversion Umphumela: i-valve yokuhlola, i-throttle valve, i-valve yokunciphisa ingcindezi, i-valve yokuhlola namanye ama-valve aqondise. Uma zifakwe ngokuphambene, i-valve ye-throttle izothinta umphumela wesevisi nokuphila; i-valve yokunciphisa ingcindezi ngeke isebenze nhlobo, futhi i-valve yokuhlola izodala ingozi. Izinyathelo: kuma-valve ajwayelekile, kunophawu lwesiqondiso emzimbeni we-valve; uma kungenjalo, kufanele ikhonjwe ngendlela efanele ngokuvumelana nesimiso sokusebenza se-valve. I-valve ye-valve yokumisa ayilingani. Uketshezi kufanele luvunyelwe ukuba ludlule embobeni ye-valve ukusuka phansi kuye phezulu, ukuze ukumelana noketshezi kube kuncane (kunqunywa ukuma), ukuvulwa konga umsebenzi (ngenxa yokucindezela okuphakeme kwe-medium), kanye nendawo ephakathi. ayicindezelwe ngemuva kokuvalwa, okulungele ukulungiswa. Lesi yisizathu sokuthi kungani i-valve yokumisa ingakwazi ukuhlehliswa. Ungayifaki i-valve yesango ibheke phansi (okungukuthi, isondo lesandla libheke phansi), ngaphandle kwalokho, okuphakathi kuzohlala isikhathi eside endaweni yekhava yevalvu, okulula ukugqwala isiqu se-valve, futhi kwenqatshelwe ezinye izidingo zenqubo. Ngesikhathi esifanayo, akulula ukushintsha ukupakisha. I-valve yesango ye-stem evulekile akufanele ifakwe ngaphansi komhlaba, ngaphandle kwalokho isiqu esiveziwe sizogqwala ngenxa yomswakama. Uma ufaka i-valve yokuhlola i-lift, qiniseka ukuthi i-valve disc imile, ukuze i-lift iguquguquke. Ivalvu yokuhlola ukushwibeka izofakwa nephinikhodi yayo ivundlile ukuze ikwazi ukushwiba kalula. Ivalvu yokukhulula ukucindezela kufanele ifakwe iqonde epayipini elivundlile futhi akufanele ithambekele kuzo zonke izinhlangothi.
