flange kaviri eccentric butterfly valve

Henry Pratt Kambani inotungamira kugadzira mavharuvhu uye mafittings, ane anopfuura 60 makore eruzivo mukupa masevhisi kuindasitiri yemagetsi. Pratt akaunzwa kuindasitiri yemagetsi kuburikidza nebasa rekugadzirisa rakaitwa paEdison Federal Building muChicago. Nzvimbo iyi yaive imwe yevagadziri vemagetsi eEdison panguva iyoyo. Mumapaipi emvura apo pasina valve uye headroom iduku, valve inodiwa. Henry Pratt Company (Henry Pratt Company) yakakumbirwa kugadzira compact valve kugadzirisa dambudziko iri. Magadzirirwo anozoitwa ndeye elastic seat butterfly valve, iro rimwe zuva richava chigadzirwa chikuru chekambani. Kusvika pakati pemakore ekuma1940, Pratt & Whitney vaizoramba vachigadzira mavharuvhu echigaro cheshavishavi pane imwe nyaya-ne-kesi, asi mushure meHondo Yenyika II, Pratt & Whitney vakasarudza kuigadzira kuita mutsara wechigadzirwa chekushandisa simba nemvura. Nhasi, Henry Pratt ave mutungamiri mumisika yemagetsi nemvura. Iyo 1100 yakatevedzana nyukireya mvura vharuvhu ndeye ASME level 2 uye 3 nyukireya ine chekuita nekuchengetedza mvura butterfly valve, inotangira pakukura kubva pa6 inches kusvika 36 inches (yakakura sezvinodiwa). Chiyero chekugadzira chakakodzera ANSI 150 # yakajairwa nhanho yekumanikidza. Kune mavharuvhu akakura kupfuura 24in uye 75 psig sevhisi giredhi, anosangana nezvinodiwa zveASME Sec. Ipa III code chikamu 1678. Zvigadzirwa zvekugadzira zvezvikamu zve1100 zvinosanganisira muviri weflange, wakagadzirwa nezvinhu zvinosangana neSA-216, Gr. WCB kana SA-516, Gr. 70; Ivhavha disc, iyo inogona kugadzirwa kana kukandwa, kana kugadzirwa nekabhoni simbi, nepo kabhoni simbi disc ine Stainless simbi vharafu chigaro mupendero inofukidza yose upamhi ari mounting pamusoro; uye zvigaro zvevharuvha yerubha, zvinosungirirwa zvachose Kana kuti zvigadziriswe mumutumbi wevharuvhu pasina kushandiswa kwetambo dzakasungirirwa. Iyo shaft yevharuvhu inogona kuve imwe-chidimbu chimiro inotambanukira kuburikidza nevhavha disc, kana inogona kuumbwa neaviri-zvidimbu shaft inoiswa muvhavha disc hub. Iyo 1200 yakatevedzana yenyukireya airvharuvhu ndeye ASME Kirasi 2 uye Kirasi 3 kuchengetedzwa kwenyukireya ine chekuita nemhepo sevhisi butterfly valve, inotangira pakukura kubva pa6in kusvika 48in. Iyo yedhizaini nhanho yakafanana neiyo 1100 yakatevedzana. Zvakafanana neiyo 1100 yakatevedzana, madhizaini eiyo 1200 akateedzana anosanganisira flange body, prefabricated or cast steel structure valve disc ine mechanicha yakagadziriswa uye inogadziriswa chigaro cherabha, uye hunde yevharuvhu inogona kuva imwe-chidimbu chimiro kana imwe- chidimbu chimiro. Zvimedu zviviri shaft. Iyo 1400 yakatevedzana nyukireya mvura vharuvhu ndeye ASME nhanho 2 uye nhanho 3 yenyukireya chengetedzo ine chekuita nemvura inopa butterfly valve, inotangira pakukura kubva pa3 inches kusvika 24 inches. Chiyero chekugadzira chinoshanda kune yakajairwa kudzvanywa chiyero ANSI 150#. Zvimiro zvekugadzira uye zvimiro zvezvikamu zve1400 zvakatevedzana zvakafanana neaya e1100 akatevedzana, uye mashandisiro avo akafanana. Triton XR-70 rubber sealing butterfly valve inosangana nezvinodiwa zveAWWA C504, uye saizi inobva pa24in kusvika 144in. Iyo yakajairika valve body style ndeye flange x flange end, mechanical joint (MJ) kuguma (24in-48in) uye flange uye MJ kuguma (24in, 30in uye 36in). Triton maficha anosanganisira Pratt E-Lok chigaro dhizaini uye kutenderera tirayi dhizaini. E-Lok valve chigaro dhizaini inogamuchirwa, uye chigaro chevharuvha yerabha chinoiswa muvharuvhu muviri kuti ipe kuvharika kwemhepo. Kuenzaniswa nechero imwe disc dhizaini parizvino iri pamusika, dhizaini yekutenderera inowana simba repamusoro nehuremu huremu. Kambani link www.henrypratt.com
