II Taboos ezingamashumi amabini anesihlanu zofakelo lwevalvu yeempahla ezomileyo, wazi kangakanani?

Taboo 11 Indlela yokufakela ivalve engalunganga. Umzekelo, indlela yokuhamba kwamanzi (umphunga) yevalve yokumisa okanye ivalve yokukhangela ichasene nophawu, isiqu sevalve sifakwe ezantsi, ivalve yokukhangela efakwe ngokuthe tye ifakwe ngokuthe tye, umqheba wevalve yesango lokunyuka okanye ivalve yebhabhathane ayinayo. indawo yokuvula nokuvala, kunye nesiqu sevalve yevalve efihliweyo ayijonganga ivelufa yokuhlola. Isiphumo: Ukusilela kwevalvu, ukutshintsha ubunzima bokulondolozwa, isikhondo esisezantsi kudla ngokubangela ukuvuza kwamanzi. Imilinganiselo: faka ngokungqongqo ngokuhambelana nemiyalelo yokufakela i-valve. Ivalve yesango enyukayo iya kuba nomphakamo owaneleyo wokuvula isikhondo. Isithuba sokujikeleza komqheba siyakuqwalaselwa ngokupheleleyo kwivalve yebhabhathane. Isiqu seevalvu ezahlukeneyo asiyi kuba ngaphantsi kwindawo ethe tye okanye ezantsi. Ivalve efihliweyo ayisayi kubonelelwa kuphela ngevalve yokuhlola ehlangabezana neemfuno zokuvula nokuvala zevalve, kodwa nesiqu sevalve siya kujongana nevalve yokuhlola. I-Taboo 12 Ukucaciswa kunye nemodeli yevalve efakiweyo ayihambelani neemfuno zoyilo. Ngokomzekelo, uxinzelelo lwe-valve lungaphantsi koxinzelelo lovavanyo lwenkqubo; xa ububanzi bombhobho wombhobho wesebe lonikezelo lwamanzi lingaphantsi okanye lilingana ne-50 mm, i-valve yesango isetyenziswa; ivalve yokumisa isetyenziselwa imibhobho eyomileyo nethe nkqo yokufudumeza kwamanzi ashushu; ivalve yebhabhathane isetyenziselwa umbhobho wokufunxa amanzi wempompo yomlilo. Umphumo: kuchaphazela ukuvulwa okuqhelekileyo kunye nokuvalwa kwe-valve kunye nokulungelelanisa ukuchasana, uxinzelelo kunye neminye imisebenzi. Nokuba kubangele ukusebenza kwenkqubo, umonakalo wevalvu unyanzelekile ukuba ulungiswe. Imilinganiselo: qhelana nobubanzi bokusetyenziswa kweevalvu ezahlukeneyo, kwaye ukhethe ukucaciswa kunye neemodeli zeevalvu ngokweemfuno zoyilo. Uxinzelelo oluncinci lwevalvu luya kuhlangabezana neemfuno zoxinzelelo lovavanyo lwenkqubo. Ngokweemfuno zenkcazo yokwakha: ivalve yokumisa iya kusetyenziswa xa ububanzi bombhobho wesebe lonikezelo lwamanzi bungaphantsi okanye bulingana ne-50mm; Ivalve yesango iya kusetyenziswa xa i-diameter ingaphezulu kwe-50mm. Ivalve yesango iya kusetyenziselwa ukufudumeza amanzi ashushu owomileyo kunye nevalve yolawulo eme nkqo, kwaye ivelufa yebhabhathane ayinakusetyenziswa kumbhobho wokufunxa impompo yomlilo. I-Taboo 13 Ngaphambi kokufakwa kwevalve, ukuhlolwa komgangatho oyimfuneko akwenziwanga njengoko kufuneka. Umphumo: ngexesha lokusebenza kwenkqubo, i-valve switch ayiguquki, ukuvala akungqongqo kwaye isiganeko sokuvuza kwamanzi (i-steam) senzeke, kubangele ukuphinda kusebenze kunye nokulungiswa, nokuba kuchaphazela ukunikezelwa kwamanzi okuqhelekileyo (umphunga). Imilinganiselo: Amandla oxinzelelo kunye novavanyo lokuqina luya kwenziwa phambi kofakelo lwevalvu. I-10% yebhetshi nganye (yephawu olufanayo, inkcazo kunye nemodeli) iya kukhethelwa uvavanyo, kwaye akukho ngaphantsi kwesinye. Ngokuba iivalve ezivaliweyo ezifakwe kumbhobho oyintloko wokunqumla, iimvavanyo zamandla kunye nokuqina ziya kuqhutywa nganye nganye. Amandla evalve kunye noxinzelelo lovavanyo lokuqina luya kuhambelana nezibonelelo zekhowudi yokwamkelwa komgangatho wokwakhiwa konikezelo lwamanzi okwakha kunye ne-drainage kunye nobunjineli bokufudumeza (GB 50242-2002). I-Taboo 14 Izinto eziphambili, izixhobo kunye neemveliso ezisetyenziselwa ulwakhiwo zikungabikho kwamaxwebhu okuchongwa komgangatho wobugcisa okanye izatifikethi zemveliso ezihlangabezana nemigangatho yangoku ekhutshwe ngurhulumente okanye uMphathiswa. Umphumo: umgangatho weprojekthi awufanelekanga, kukho iingozi ezinokuthi zikwazi ukuhanjiswa kwaye zisetyenziswe ngexesha, ngoko kufuneka zihlaziywe kwaye zilungiswe; ixesha lokwakha libambezelekile, kwaye igalelo labasebenzi kunye nezinto eziphathekayo liyanda. Imilinganiselo: izinto eziphambili, izixhobo kunye neemveliso ezisetyenziselwa unikezelo lwamanzi kunye nokuhamba kwamanzi kunye nokufudumeza kunye nobunjineli bococeko luya kunikwa amaxwebhu omgangatho wobugcisa okanye iziqinisekiso zemveliso ezihlangabezana nemigangatho ekhoyo ekhutshwe ngurhulumente okanye uMphathiswa; igama lemveliso, imodeli, inkcazo, ikhowudi yomgangatho wesizwe, umhla wokuhanjiswa, igama lomenzi kunye nendawo, isatifikethi sokuhlolwa kwemveliso yokuhanjiswa okanye ikhowudi iya kuboniswa. I-Taboo ye-15 ye-Valve inversion Isiphumo: i-valve yokukhangela, i-valve ye-throttle, i-valve yokunciphisa uxinzelelo, i-valve yokukhangela kunye nezinye iivalve ziqondisa. Ukuba zifakwe ngokuphambeneyo, i-valve ye-throttle iya kuchaphazela umphumo wenkonzo kunye nobomi; ivalve yokunciphisa uxinzelelo ayiyi kusebenza kwaphela, kwaye ivalve yokukhangela iya kubangela ingozi. Imilinganiselo: kwiivalvu eziqhelekileyo, kukho uphawu lwesalathiso kumzimba wevalvu; ukuba akunjalo, kufuneka ichongwe ngokuchanekileyo ngokwemigaqo yokusebenza yevalve. Umngxuma wevalve wevalve yokumisa awulungelelaniswanga. Ulwelo kufuneka luvunyelwe ukuba ludlule kwi-valve port ukusuka ezantsi ukuya phezulu, ukwenzela ukuba ukuxhathisa ulwelo kuncinci (kunqunywe yimilo), ukuvulwa kukugcina umsebenzi (ngenxa yoxinzelelo oluphezulu lwe-medium), kunye ne-medium. ayicinezeleki emva kokuvalwa, ekulungele ukugcinwa. Esi sizathu sokuba kutheni ivalve yokumisa ingakwazi ukuguqulwa. Musa ukufaka ivalve yesango ijonge ezantsi (okt ivili lesandla lisezantsi), kungenjalo, i-medium iya kuhlala kwisithuba sokugquma sevalve ixesha elide, ekulula ukurhwaphiliza isikhondo sevalve, kwaye akuvunyelwanga ziimfuno ezithile zenkqubo. Ngexesha elifanayo, akunzima ukutshintsha ukupakisha. Ivalve yesango evulekileyo ayisayi kufakwa ngaphantsi komhlaba, kungenjalo isikhondo esivelileyo siya kudleka ngenxa yokufuma. Xa ufaka i-valve yokukhangela i-valve, qiniseka ukuba i-disc ye-valve imile, ukwenzela ukuba ukuphakama kuguquguquke. Ivalve yokujonga ujingi iya kufakwa kunye ne-pin shaft ethe tye ukuze ijinga-bhetyebhetye. Ivalve yokukhulula uxinzelelo iya kufakwa ngokuthe nkqo kumbhobho othe tye kwaye ayisayi kuthotyelwa macala onke.
