Inkampani kaHenry Pratt ngumvelisi okhokelayo weevalvu kunye nezinto zokufakelwa uneminyaka engama-60 yamava okusebenzela ishishini lamandla.
IPlatt yaziswa kushishino lwamandla ngomsebenzi wokulondoloza kwiSakhiwo se-Federal Edison kwisixeko saseChicago.Isiza sasingomnye wabavelisi bamandla abaphambili be-Edison ngelo xesha.Ivalve iyafuneka kumgca wamanzi okwangoku ongenaso ivalve kwaye inentloko encinci kakhulu.UHenry Platt & Inkampani yacelwa ukuba iyile ivalve ebambeneyo ukusombulula le ngxaki.Uyilo oluveliswayo sisivalo esihlala ibhabhathane esomeleleyo esiya kuthi ngenye imini sibe yimveliso ephambili yenkampani.
U-Pratt uqhubekile nokuvelisa iivalve zebhabhathane ezihlala zihleli kwimeko-nye-case de kwaba phakathi kwiminyaka yee-1940s, kodwa emva kweMfazwe Yehlabathi II uPratt wagqiba ekubeni aphuhlise ivalve ibe ngumgca wemveliso yokusetyenziswa kwamandla kunye namanzi. Namhlanje, uHenry Platt & Company yinkokeli yemarike kumbane namanzi.
I-1100 Series Nuclear Water Valves zi-ASME Udidi lwesi-2 kunye ne-3 yokhuseleko lwenyukliya enxulumene nonikezelo lwamanzi izivalo zebhabhathane ezifumaneka ngokobukhulu ukusuka kwi-6″ ukuya kuma-36″ (enkulu xa kuceliwe). Amazinga oyilo asebenza kuxinzelelo oluqhelekileyo lwe-ANSI 150# iklasi.Ivunyelwe yi-ASME I-Sec yeevalvu ezinkulu kune-intshi ezingama-24, i-75 psig yenkonzo yokukala.IIII Code Class 1678, Iyafumaneka.
Iimpawu zokuyila ze-1100 series ziquka imizimba e-flanged eyenziwe nge-SA-216, i-Gr izinto ezihambelanayo.WCB okanye SA-516, Gr.70; iidiskhi zevalve, zolwakhiwo olwenziweyo okanye olwakhiweyo okanye intsimbi yekhabhoni, iidiskhi zentsimbi yekhabhoni ezinomphetho wesihlalo sentsimbi engenasici esigubungela bonke ububanzi bomphezulu wesihlalo; kunye nezihlalo zerabha, ezibotshelelwe ngokusisigxina okanye zilungiswe ngoomatshini kumzimba wevalve, ngaphandle kokusetyenziswa kweziqhoboshi ezinentambo. kwi-disc hub.
I-1200 Series Nuclear Air Valves zi-ASME Class 2 kunye ne-3 yenkonzo yokhuseleko lwenyukliya enxulumene nenkonzo yomoya yeevalvu zebhabhathane ezifumaneka ngobukhulu 6″ ukuya kuma-48″.Iklasi yoyilo iyafana nothotho lwe-1100.
Iimpawu zokuyila ze-1200 series zifana nochungechunge lwe-1100, kubandakanywa imizimba ene-flanged, i-discs yokwakha eyenziwe okanye eyenziwe ngentsimbi enezihlalo zerabha ezilungiswe ngoomatshini kunye nezilungelelanisiweyo, kunye neeshafti ezinokuthi zibe yinto enye yokwakha okanye isakhiwo esisodwa. i-piece shaft.
Iivalvu ze-1400 zeNyukliya zaManzi zeNyukliya zi-ASME Udidi lwesi-2 kunye nesi-3 sokhuseleko lwenyukliya olunxulumene nonikezelo lwamanzi iivalvu zebhabhathane ezifumaneka ngokobukhulu ukusuka ku-3″ ukuya kuma-24″.Umlinganiselo woyilo usebenza kumazinga oxinzelelo asemgangathweni ANSI 150#.
Iimpawu zoyilo kunye nezinto zokwakha ze-1400 series zilinganisa ezo ze-1100 series kuba injongo yazo iyafana.
I-Triton XR-70 I-Rubber etywiniweyo ye-Butterfly Valves ihlangabezana neemfuno ze-AWWA C504 kwaye zifumaneka ngobukhulu ukusuka kwi-24 "ukuya kwi-144" Iintlobo zomzimba eziqhelekileyo ziyi-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 ze-Triton ziquka i-Pratt E-Lok yokuyila isihlalo kunye nokuhamba-nge-disc design.Ngoyilo lwesihlalo se-E-Lok, isihlalo se-rubber sifakwe kumzimba we-valve ukubonelela ngokuvalwa kwe-hermetic. kubunzima obuphantsi kunalo naluphi na olunye uyilo lwediski olukhoyo ngoku kwimarike.
