ductile iron rubber seal 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 muEdison Federal Building muChicago. Nzvimbo iyi yaive imwe yevagadziri vemagetsi eEdison panguva iyoyo. Mumapaipi emvura apo pasina valve uye headroom iduku, valve inodiwa. Iyo 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 vakaramba vachigadzira mavharuvhu agere eshavishavi anochinjika zvichienderana nemamiriro ezvinhu, asi mushure meHondo Yenyika II, Pratt & Whitney vakasarudza kuigadzira kuita mutsara wesimba nemvura yekushandisa. Nhasi, Henry Pratt ave mutungamiri mumisika yemagetsi nemvura. Iyo 1100 yakatevedzana nyukireya yemvura vharuvhu iASME level 2 uye 3 nyukireya ine chekuita nekuchengetedza mvura butterfly valve, inotangira pakukura kubva pa6 inches kusvika 36 inches (uye yakakura sezvinodiwa). Chiyero chekugadzira chakakodzera giredhi yekumanikidza ye ANSI 150 #. Kune mavharuvhu akakura kupfuura 24in uye 75 psig service level, anosangana nezvinodiwa zveASME Sec. Ipa III code chikamu 1678. Zvigadzirwa zvekugadzira zve 1100 series zvinosanganisira flanged valve body yakagadzirwa 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 chigaro chevhavha yerubha, iyo yakagadziriswa zvachose kana kuti yakagadzirwa nemagetsi pavhavha Mumuviri, hapana zvigadziro zvakasungirirwa zvinodiwa. Ivhavhavhavhavha inogona kuva imwe-chidimbu chimiro chinopfuurira kuburikidza nevhavha disc, kana inogona kuumbwa ne-two-piece 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 yemvura vharuvhu ndeye ASME nhanho 2 uye 3 kuchengetedzwa kwenyukireya ine chekuita nemvura inopihwa 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-sealed butterfly valve inosangana nezvinodiwa zveAWWA C504, ine hukuru hunobva pa 24 inches kusvika 144 inches. 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. Iyo E-Lok valve yechigaro dhizaini inogamuchirwa, uye chigaro chevharuvha yerabha yakaiswa mumutumbi wevharuvhu kuti ipe kuvharika kwemhepo. Kuenzaniswa nemamwe madhizaini edhisiki parizvino ari pamusika, dhizaini yekutenderera inowana simba repamusoro nehuremu huremu. Kambani link www.henrypratt.com
