i-wcb butterfly valve

Inkampani kaHenry Pratt ingumkhiqizi ohamba phambili wamavalvu nokufakwa, oneminyaka engaphezu kwengama-60 yesipiliyoni ekuhlinzekeni ngezinsizakalo embonini yamandla.
UPratt wethulwa embonini kagesi ngomsebenzi wokulungisa e-Edison Federal Building eChicago. Isayithi lalingomunye wabakhiqizi bamandla abakhulu be-Edison ngaleso sikhathi. Emapayipini amanzi lapho ingekho i-valve njengamanje futhi igumbi lokufundela lincane, i-valve iyadingeka. I-Henry Pratt Company yacelwa ukuba idizayine ivalvu ehlangene ukuze ixazulule le nkinga. Umklamo owumphumela uyi-valve yesihlalo esinwebekayo sovemvane, ngelinye ilanga ezoba umkhiqizo oyinhloko wenkampani.
Kuze kube maphakathi nawo-1940, uPratt noWhitney babesakhiqiza amavalvu ezivamvane ezihlala njalo njalo, kodwa ngemva kweMpi Yezwe II, uPratt noWhitney banquma ukuyithuthukisa ibe umugqa womkhiqizo wokusebenzisa amandla namanzi. Namuhla, uHenry Pratt usephenduke umholi ezimakethe zikagesi namanzi.
Ivalvu yamanzi enuzi ewuchungechunge engu-1100 iyileveli ye-ASME 2 kanye ne-3 ye-nuclear ehlobene nokuphepha kwe-butterfly valve, esukela ngosayizi osuka kumayintshi angu-6 ukuya kwangu-36 amayintshi (futhi mkhulu njengoba kudingeka). Isilinganiso somklamo sifanele izinga lokucindezela elijwayelekile le-ANSI 150#. Kumavalvu amakhulu kuno-24in kanye neleveli yesevisi ye-psig engu-75, ahlangabezana nezimfuneko ze-ASME Sec. Nikeza isigaba sekhodi ye-III 1678.
Izici zokuklama zochungechunge lwe-1100 zifaka umzimba we-valve ene-flanged eyenziwe ngezinto ezihlangabezana ne-SA-216, Gr. I-WCB noma i-SA-516, Gr. 70; I-valve disc, engakhiwa noma iphonswe, noma yenziwe nge-carbon steel, kuyilapho i-carbon steel disc inomphetho wesihlalo se-valve yensimbi engagqwali emboza bonke ububanzi bendawo ekhuphukayo; kanye nesihlalo se-valve yenjoloba, esilungiswe unomphela noma esimiswe ngomshini ku-valve Emzimbeni, azikho izibophelelo ezinentambo ezidingekayo. I-valve shaft ingaba isakhiwo esiwucezu olulodwa esidlulela kudiski ye-valve, noma ingakhiwa i-shaft enezingcezu ezimbili efakwe kuhabhu le-valve disc.
I-valve yomoya we-nuclear yochungechunge engu-1200 yi-ASME Class 2 kanye ne-Class 3 ye-nuclear ehlobene nesevisi ye-air butterfly valve, esukela ngosayizi osuka ku-6in kuya ku-48in. Izinga lokuklama liyafana nochungechunge lwe-1100.
Ngokufana nochungechunge lwe-1100, izici zokuklama zochungechunge lwe-1200 zihlanganisa umzimba we-flange, i-disc ye-valve yesakhiwo sensimbi esenziwe ngaphambili noma esakhiwe esinesihlalo senjoloba esingaguquki futhi esilungisekayo, futhi isiqu se-valve singaba ucezu olulodwa noma eyodwa- isakhiwo socezu . I-shaft enezicucu ezimbili.
I-valve yamanzi enuzi ewuchungechunge engu-1400 iyileveli ye-ASME 2 kanye ne-3 ye-nuclear ehlobene nokuphepha kwe-butterfly valve, esukela ngosayizi ukusuka kumayintshi angu-3 ukuya kwangu-24 amayintshi. Isilinganiso somklamo sifanele isilinganiso sokucindezela esijwayelekile ANSI 150#.
Izici zokuklama nezinto zokwakha zochungechunge lwe-1400 zifana nalezo zochungechunge lwe-1100, futhi ukusetshenziswa kwazo kuyafana.
Ivalvu uvemvane evalwe ngerabha i-Triton XR-70 ihlangabezana nezidingo ze-AWWA C504, enosayizi osuka kumayintshi angu-24 ukuya kwangu-144. Isitayela somzimba we-valve esijwayelekile siyi-flange x isiphetho se-flange, isiphetho se-mechanical joint (MJ) (24in-48in) kanye ne-flange kanye nesiphetho se-MJ (24in, 30in kanye ne-36in).
Izici ze-Triton zifaka ukwakhiwa kwesihlalo se-Pratt E-Lok kanye ne-circulation tray design. Idizayini yesihlalo se-valve ye-E-Lok iyamukelwa, futhi isihlalo se-valve yenjoloba sifakwe emzimbeni we-valve ukunikeza ukuvala okungangeni komoya. Uma kuqhathaniswa nanoma yimiphi eminye imiklamo yediski emakethe njengamanje, ukwakheka kwediski elijikelezayo kufinyelela amandla aphezulu ngesisindo esilula.

Izindaba zamandla kanye nama-athikili anezici ezijulile mayelana namadili akamuva abahlinzeki bamandla, ukuqanjwa kabusha kwamandla kanye nezitayela zamandla avuselelekayo, ilanga, umoya wasogwini lolwandle, amandla kagesi, amalahle namandla enuzi.
