Kampani ya Henry Pratt ndiyomwe ikutsogolera kupanga mavavu ndi zoyitanira omwe ali ndi zaka zopitilira 60 akugwira ntchito yopangira magetsi.

Kampani ya Henry Pratt ndiyomwe ikutsogolera kupanga mavavu ndi zoyitanira omwe ali ndi zaka zopitilira 60 akugwira ntchito yopangira magetsi.
Platt anadziwitsidwa ku makampani opanga magetsi pogwiritsa ntchito ntchito yokonza nyumba ya Federal Edison Building mumzinda wa Chicago. Malowa anali amodzi mwa opanga magetsi akuluakulu a Edison panthawiyo. ali ndi mutu waung'ono kwambiri.Henry Platt & Company anafunsidwa kuti apange valavu yowonongeka kuti athetse vutoli.Mapangidwe opangidwa ndi valavu yagulugufe yomwe imakhala yokhazikika yomwe tsiku lina idzakhala chinthu chachikulu cha kampani.
Pratt adapitiliza kupanga ma valve agulugufe okhala mokhazikika motsatana-tsatana mpaka pakati pa zaka za m'ma 1940, koma Nkhondo Yachiwiri Yapadziko Lonse itatha, Pratt adaganiza zopanga valavuyo kukhala mzere wazogwiritsa ntchito mphamvu ndi madzi. Lero, Henry Platt & Company ndi mtsogoleri wamsika wamagetsi ndi madzi.
1100 Series Nuclear Water Valves ndi ASME Class 2 ndi 3 mavavu agulugufe okhudzana ndi chitetezo cha nyukiliya omwe amapezeka mu makulidwe kuyambira 6 ″ mpaka 36 ″ (zazikulu zikafunsidwa).Maganizo amapangidwe amagwira ntchito pamiyeso yokhazikika ya ANSI 150# class.Yololedwa ndi ASME Sec kwa mavavu akulu kuposa mainchesi 24, 75 psig service rating.III Code Class 1678, Available.
Mapangidwe amtundu wa 1100 amaphatikizapo matupi opangidwa ndi flanged opangidwa ndi SA-216, Gr zipangizo zogwirizana.WCB kapena SA-516, Gr.70; ma valve discs, omanga opangidwa kapena opangidwa kapena chitsulo cha kaboni, ma disc a carbon steel valve okhala ndi chitsulo chosapanga dzimbiri m'mphepete mwake chomwe chimaphimba m'lifupi lonse la mpando; ndi mipando ya mphira, yomwe imamangiriridwa kosatha kapena yokhazikika m'thupi la valve, popanda kugwiritsa ntchito zomangira zomangira. kulowa mu disk hub.
1200 Series Nuclear Air Valves ndi ASME Class 2 ndi 3 mavavu a butterfly okhudzana ndi chitetezo cha nyukiliya omwe amapezeka mu kukula kwa 6 "mpaka 48". Gulu la mapangidwe ndilofanana ndi mndandanda wa 1100.
Mapangidwe a mndandanda wa 1200 ndi ofanana ndi mndandanda wa 1100, kuphatikizapo matupi opangidwa ndi flanged, zitsulo zopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangidwa ndi makina opangidwa ndi mipando ya rabara yokhazikika komanso yosinthika, ndi ma shafts omwe angakhale opangidwa ndi chidutswa chimodzi kapena chidutswa chimodzi. chidutswa cha shaft.
Ma valve a 1400 Series Nuclear Water Valves ndi ASME Class 2 ndi 3 ma valve a butterfly okhudzana ndi chitetezo cha nyukiliya omwe amapezeka mumiyeso kuyambira 3″ mpaka 24″.Mapangidwe apangidwe amagwira ntchito pazitsulo zokhazikika za ANSI 150#.
Mapangidwe ndi zida zomangira mndandanda wa 1400 amatsanzira za mndandanda wa 1100 chifukwa cholinga chawo ndi chofanana.
Triton XR-70 Rubber Sealed Butterfly Valves amakwaniritsa zofunikira za AWWA C504 ndipo akupezeka mu makulidwe kuyambira 24″ mpaka 144″. Mitundu yodziwika bwino ya thupi ndi flange x flange end, mechanical joint (MJ) end (24in-48in), ndi flange ndi MJ end (24in, 30in, ndi 36in).
Zinthu za Triton zimaphatikizapo mapangidwe a mpando wa Pratt E-Lok ndikuyenda-kupyolera mu disk design.Ndi mapangidwe a mpando wa E-Lok, mpando wa rabara umayikidwa mu thupi la valve kuti upereke kutsekedwa kwa hermetic. pa kulemera kochepa kusiyana ndi mapangidwe ena aliwonse omwe ali pamsika panopa.
