Henry Pratt ndiye anotungamira kugadzira mavharuvhu uye zvishongedzo, ane anopfuura makore makumi matanhatu echiitiko chebasa muindasitiri yemagetsi.
Pratt akapinda muindasitiri yemagetsi kuburikidza nebasa rekugadzirisa paFederal Edison Building muChicago. Iyi nzvimbo yaive imwe yenzvimbo dzekugadzira magetsi dzeEdison panguva iyoyo. Ivhavha inodiwa mupombi yemvura iyo parizvino isina vharafu uye ine diki headroom. Henry Pratt akakumbirwa kugadzira compact valve kugadzirisa dambudziko iri. Dhizaini inogadzirwa ndeye elastic seat butterfly valve, iro rimwe zuva richava chigadzirwa chikuru chekambani.
Kusvika pakati pe-1940s, Pratt akaenderera mberi nekugadzira elastic sealing butterfly mavharuvhu zvinoenderana nemamiriro chaiwo, asi mushure meHondo Yenyika II, Pratt akafunga kugadzira vharuvhu semutsara wechigadzirwa chemagetsi uye mvura yekudyara mashandisirwo. Nhasi, Henry Pratt ndiye mutungamiri mumisika yemasimba uye mvura.
Iyo 1100 yakatevedzana nyukireya vharafu yemvura idanho reASME 2 uye 3 kuchengetedzwa kwenyukireya ine chekuita nemvura yeshavishavi vharuvhu, inotangira pakukura kubva pa6 inches kusvika 36 inches (uye yakakura sezvinodiwa). Dhizaini yegiredhi inokodzera ANSI 150 # yakajairwa giredhi yekumanikidza. Kune mavharuvhu makuru kupfuura 24 inches, 75 psig service giredhi, ASME Sec inobvumira. III kodhi chikamu 1678, iripo.
Mamiriro ekugadzira eiyo 1100 akatevedzana anosanganisira iyo flange body, iyo inogadzirwa nezvinhu zvinoenderana neSA-216, Gr. WCB kana SA-516, Gr. 70; A valve disc, iyo inogona kugadzirwa kana kukandwa chimiro kana kabhoni simbi. Iyo kabhoni simbi disc ine Stainless simbi vharafu chigaro mupendero, kufukidza yose upamhi hwechigaro vharafu pamusoro; uye chigaro chevharuvha yerabha, iyo inosungirirwa zvachose kana mechanically yakagadziriswa mumutumbi wevharuvhu pasina Kushandisa tambo dzakasungirirwa. Ivhavhavhavhavha inogona kuva imwe-chidimbu chimiro chinopfuurira kuburikidza nevhavha disc, kana inogona kuva ne-two-piece shaft yakaiswa muvhavha disc hub.
Iyo 1200 yakatevedzana yenyukireya airvharuvhu iASME Kirasi 2 uye Kirasi 3 kuchengetedzwa kwenyukireya ine chekuita nemhepo sevhisi vharuvhu, inotangira pakukura kubva pa6 inches kusvika 48 inches. Iyo yedhizaini nhanho yakafanana neiyo 1100 yakatevedzana.
Mamiriro ekugadzira eiyo 1200 akatevedzana akafanana neaya e1100 akateedzana, anosanganisira flange body, prefabricated or cast steel structure valve disc ine mechanical yakagadziriswa uye inogadziriswa chigaro cherabha, uye imwe-chidimbu chimiro kana maviri-chidimbu shaft. .
Iyo 1400 yakatevedzana nyukireya vharafu yemvura idanho reASME 2 uye 3 nyukireya ine chekuita nekuchengetedza mvura butterfly valve, inotangira pakukura kubva pa3 inches kusvika 24 inches. Iyo dhizaini giredhi yakakodzera kune yakajairwa kumanikidza giredhi ANSI 150 # giredhi.
Iyo dhizaini maficha uye zvimiro zveiyo 1400 akateedzera iyo 1100 akatevedzana nekuti mashandisiro avo akafanana.
Triton XR-70 rubber-sealed butterfly valve inosangana neAWWA C504 zvinodiwa, kubva pakukura kubva pa 24 inches kusvika 144 inches. Standard valve body styles ndeye flange x flange end, mechanical joint (MJ) end (24 inches-48 inches), uye flange neMJ end (24 inches, 30 inches, uye 36 inches).
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. Iyo yekutenderera tireyi dhizaini inowana yakakwirira simba nehuremu huremu kupfuura chero imwe tireyi dhizaini pari zvino pamusika. Kambani link www.henrypratt.com
Nhau dzesimba uye zvakadzama zvinoratidzira zvinyorwa pamusoro pesimba rekuvandudza uye mafambiro mune ichangoburwa simba rekutengesa magetsi, simba rinogoneka, solar, mhepo yekumahombekombe, hydropower, marasha, uye simba renyukireya.
