WCb butterfly valve

Inkampani kaHenry Pratt ngumvelisi ohamba phambili weevalvu kunye nokufakelwa, kunye neminyaka engaphezu kwe-60 yamava ekuboneleleni ngeenkonzo kwishishini lamandla. I-Pratt yaziswa kwishishini lamandla ngomsebenzi wokulondoloza kwi-Edison Federal Building e-Chicago. Isayithi yayingomnye wabavelisi bamandla abakhulu be-Edison ngelo xesha. Kwimibhobho yamanzi apho kungekho valve ngoku kwaye igumbi lentloko lincinci, ivalve iyafuneka. Inkampani kaHenry Pratt yacelwa ukuba iyile ivalve ebambeneyo ukusombulula le ngxaki. Uyilo olusisiphumo sisivalo esinelastiki sesitulo sebhabhathane, esiya kuthi ngenye imini sibe yimveliso ephambili yenkampani. Kuze kube phakathi kwiminyaka yee-1940, uPratt noWhitney babesavelisa iivalve zebhabhathane eziguquguqukayo kwimeko nganye, kodwa emva kweMfazwe Yehlabathi II, uPratt noWhitney bagqiba ekubeni bayiphuhlise ibe ngumgca wemveliso wamandla kunye nosetyenziso lwamanzi. Namhlanje, uHenry Pratt uye waba yinkokeli kwiimarike zombane kunye namanzi. Ivalve yamanzi enyukliya ye-1100 yinqanaba lesi-2 le-ASME kunye ne-3 enxulumene nokhuseleko lwenyukliya enxulumene nonikezelo lwamanzi ivelufa yebhabhathane, esukela kubukhulu obusuka kwi-intshi ezi-6 ukuya kwi-intshi ezingama-36 (kwaye inkulu njengoko kufuneka). Ukulinganiswa koyilo kufanelekileyo kwinqanaba loxinzelelo oluqhelekileyo lwe-ANSI 150 #. Kwiivalvu ezinkulu kune-24in kunye ne-75 inqanaba lenkonzo ye-psig, ziyahlangabezana neemfuno ze-ASME Sec. Ukubonelela nge-III ikhowudi yodidi lwe-1678. Iimpawu zoyilo zechungechunge lwe-1100 ziquka i-valve ye-flanged body eyenziwe ngezinto ezidibana ne-SA-216, i-Gr. WCB okanye SA-516, Gr. 70; I-disc ye-valve, enokuthi yenziwe okanye iphoswe, okanye yenziwe nge-carbon steel, ngelixa i-carbon steel disc inomphetho wesihlalo sevalve yensimbi engenasici egubungela yonke ububanzi bendawo yokunyuka; kunye nesihlalo sevalve yerabha, esisigxina okanye egxininiswe ngoomatshini kwivalve Emzimbeni, akukho zibophelelo ezinentambo ezifunekayo. I-valve shaft ingaba sisakhiwo esinye esinabela kwi-disc ye-valve, okanye inokuqulunqwa kwi-shaft-piece-piece shaft efakwe kwi-disc hub ye-valve. Ivalve yomoya yenyukliya ye-1200 yi-ASME Udidi lwesi-2 kunye noDidi 3 lwenkonzo yokhuseleko lwenyukliya enxulumene nenkonzo yomoya ivelufa yebhabhathane, esusela kubukhulu obusuka ku-6in ukuya kuma-48in. Umgangatho woyilo ufana nochungechunge lwe-1100. Ngokufana nochungechunge lwe-1100, iimpawu zoyilo zechungechunge lwe-1200 zibandakanya umzimba we-flange, i-disc ye-valve yesakhiwo okanye i-cast steel structure kunye nesihlalo serabha esisisigxina kunye nesilungelelanisiweyo, kunye nesiqu se-valve sinokuba yinto enye okanye enye- isakhiwo seqhekeza. I-shaft enamacandelo amabini. Ivalve yamanzi enyukliya ye-1400 yinqanaba lesi-2 le-ASME kunye ne-3 lokhuseleko lwenyukliya enxulumene nonikezelo lwamanzi ivelufa yebhabhathane, esukela kubukhulu obusuka kwi-intshi ezi-3 ukuya kwi-intshi ezingama-24. Umlinganiselo woyilo ufanelekile kumlinganiselo woxinzelelo oqhelekileyo we-ANSI 150 #. Iimpawu zoyilo kunye nezakhiwo ze-1400 series zifana nezo ze-1100 series, kwaye ukusetyenziswa kwazo kuyafana. I-valve ye-butterfly etywiniweyo ye-Triton XR-70 ihlangabezana neemfuno ze-AWWA C504, kunye nobukhulu obuvela kwi-intshi ezingama-24 ukuya kwi-intshi ze-144. Isitayela somzimba we-valve eqhelekileyo yi-flange x isiphelo se-flange, i-mechanical joint (MJ) ekupheleni (24in-48in) kunye ne-flange kunye ne-MJ ekupheleni (24in, 30in kunye ne-36in). Iimpawu zeTriton zibandakanya uyilo lwesihlalo sePratt E-Lok kunye noyilo lwetreyi yokujikeleza. Uyilo lwesitulo sevalve ye-E-Lok luyamkelwa, kwaye isihlalo sevalve yerabha sifakwe kumzimba wevalvu ukubonelela ngokuvalwa komoya. Xa kuthelekiswa naluphi na olunye uyilo lwediskhi okwangoku kwimarike, uyilo lwediskhi yokujikeleza lufezekisa amandla aphezulu kunye nobunzima obulula. Ikhonkco leNkampani www.henrypratt.com Iindaba zamandla kunye namanqaku anzulu malunga nezivumelwano zamva nje zababoneleli bamandla, iinguqulelo zamandla kunye neentsingiselo zamandla ahlaziyekayo, ilanga, umoya ongaselunxwemeni, amandla ombane, amalahle kunye namandla enyukliya.
