Inkampani kaHenry Pratt ingumkhiqizi ohamba phambili wamavalvu nezinto ezifakwayo onolwazi olungaphezu kweminyaka engama-60 esebenzela imboni yamandla.

Inkampani kaHenry Pratt ingumkhiqizi ohamba phambili wamavalvu nezinto ezifakwayo onolwazi olungaphezu kweminyaka engama-60 esebenzela imboni yamandla.
IPlatt yethulwa embonini kagesi ngomsebenzi wokulungisa e-Federal Edison Building edolobheni laseChicago.Le ndawo yayingomunye wabakhiqizi bakagesi abakhulu be-Edison ngaleso sikhathi. ine-headroom encane kakhulu.UHenry Platt & Company wacelwa ukuba aklame ivalvu ehlangene ukuze kuxazululwe le nkinga.Umklamo okhiqizwa ivalve uvemvane ohlezi eqinile oyoba ngolunye usuku umkhiqizo oyinhloko wenkampani.
UPratt waqhubeka nokukhiqiza amavalvu ovemvane ahlezi eqinile njalonjalo kwaze kwaba maphakathi nawo-1940, kodwa ngemva kweMpi Yezwe II uPratt wanquma ukuthuthukisa ivalvu ibe umugqa womkhiqizo wokusebenzisa amandla namanzi. Namuhla, uHenry Platt & Company ungumholi wemakethe kugesi namanzi.
I-1100 Series Nuclear Water Valves ayi-ASME Class 2 kanye namavalvu e-butterfly ahlobene nokuphepha kwe-nuclear atholakala ngosayizi ukusuka ku-6″ kuya ku-36″ (amakhudlwana uma ucelwa). Izilinganiso zedizayini zisebenza ezilinganisweni zokucindezela ezijwayelekile ze-ANSI 150# class.Kuvunyelwe yi-ASME I-Sec yamavalvu amakhulu kuno-24 amayintshi, 75 psig service rating.III Code Class 1678, Iyatholakala.
Izici zedizayini zochungechunge lwe-1100 zifaka imizimba ene-flanged eyenziwe nge-SA-216, izinto ezihambisana ne-Gr.WCB noma i-SA-516, Gr.70; ama-valve disc, okwakhiwa kwendwangu noma okuphonsiwe noma insimbi ye-carbon, amadiski e-carbon steel valve anomphetho wesihlalo sensimbi engagqwali amboze bonke ububanzi bendawo yokuhlala; kanye nezihlalo zenjoloba, eziboshelwe unomphela noma zilungiswe ngomshini emzimbeni we-valve, ngaphandle kokusetshenziswa kwezibophelelo ezinentambo.I-valve shaft ingaba ukwakhiwa kocezu olulodwa olunwebeka nge-valve disc, noma ingaba ne-shaft enezicucu ezimbili efakiwe. ungene ku-disc hub.
I-1200 Series Nuclear Air Valves ayi-ASME Class 2 kanye namavalvu e-butterfly ahlobene nokuphepha kwenuzi oku-3 atholakala ngosayizi 6″ kuya ku-48″. Isigaba sokuklama siyefana nochungechunge lwe-1100.
Izici zokuklama zochungechunge lwe-1200 zifana nochungechunge lwe-1100, okuhlanganisa imizimba e-flanged, amadiski okwakhiwa kwensimbi akhiwe noma acijile anezihlalo zenjoloba ezilungiswe ngomshini nezilungisekayo, namashafti angaba ngokwakhiwa kocezu olulodwa noma ucezu olulodwa. ucezu shaft.
I-1400 Series Nuclear Water Valves ayi-ASME Class 2 kanye namavalvu e-butterfly ahlobene nokuphepha kwenuzi atholakala ngosayizi ukusuka ku-3″ ukuya ku-24″.Izilinganiso zomklamo zisebenza ezilinganisweni zokucindezela ezijwayelekile ANSI 150#.
Izici zokuklama nezinto zokwakha zochungechunge lwe-1400 zilingisa lezo zochungechunge lwe-1100 ngoba inhloso yazo iyafana.
I-Triton XR-70 Rubber Sealed Butterfly Valves ihlangabezana nezimfuneko ze-AWWA C504 futhi atholakala ngosayizi ukusuka ku-24″ kuya ku-144″.Izinhlobo zomzimba ezijwayelekile ziyi-flange x isiphetho se-flange, isiphetho se-mechanical joint (MJ) (24in-48in), ne-flange nesiphetho se-MJ (24in, 30in, kanye 36in).
Izici ze-Triton zihlanganisa umklamo wesihlalo se-Pratt E-Lok kanye ne-flow-through disc design.Ngomklamo wesihlalo se-E-Lok, isihlalo senjoloba sifakwe emzimbeni we-valve ukuze sinikeze ukuvala kwe-hermetic.Umklamo we-flow-through disc uzuza amandla amakhulu ngesisindo esiphansi kunanoma yimuphi omunye umklamo wediski osemakethe njengamanje.
