Iivalve zebhabhathane VS Ivalve yeBhola, indlela yokukhetha ivalve efanelekileyo oyifunayo

Ubude bomzimba:

Iivalve zebhabhathane zinobude bomzimba obufutshane xa kuthelekiswa nobukhulu obufanayo beevalvu zebhola.

Ke iivalvu zeButterfly zixinene ngakumbi kwaye zigcina indawo ngexesha lofakelo.

Iivalvu zeButterfly ubude (Face to Face Dimension) idibana nomgangatho we-EN558 series 20, Series 13, Series 14. Olona luhlu lude ubuso ngobuso yi-Series EN558 series 14. (Ilingana ne-DIN3202 F4), Ezinye ii-series zisetyenziswa kakhulu kwaye ubude bazo bufutshane kakhulu emva koko EN5458 series EN5558 mfutshane kakhulu ke EN5458 . kunye nomzimba omncinci uquka i-wafer kunye ne-lug kunye noyilo lwecandelo le-U.

Iivalvu zebhola ubude (I-face-to-face Dimension) idibana nomgangatho we-ANSI B16.10, Okanye i-DIN3202 F1, F4 & F5), i-DIN3201 F1 & F5 inde kakhulu kunothotho lwe-DIN3202 F4. Ke, sinokuthi obona bude bufutshane beevalvu zebhola bubude be-DIN3202 F4. Ide kakhulu kuneevalvu zeButterfly eziqhelekileyo Series 13 & Series 20.

Ke kulwakhiwo lwenkqubo yemibhobho emitsha, iivalvu zebhabhathane zixabisa kakhulu ngenxa yoyilo lomzimba walo oxineneyo. Kwaye ukuba indawo yokufakela iyanyanzeliswa, iivalve zebhabhathane zicetywa ngamandla.

Ubukhulu

Iivalve zebhola ziqhele ukusetyenziswa kubungakanani obuncinci bombhobho ongaphantsi kwe-2”, njenge 1/4” 3/8”, 1/2”1“ & 2",Iivalvu zebhabhathane kunzima ukwenza ngokobukhulu obuncinci.

Ngokwesiqhelo iivalvu zeButterfly ziqala kubukhulu 2” Ukuba uyilo lombhobho ungaphantsi/Incinci kune-2” DN50, iivalve zebhola lukhetho olulungileyo.

Ukusuka kubukhulu be-1/4 "ukuya ku-2" (DN8-DN50), iivalve zebhola lolona khetho lulungileyo kunye noqhagamshelo olunentambo kunye noqhagamshelo lweflange.

Ukususela kubukhulu be-2 "ukuya kwi-12" (DN50-DN300), zombini iivalve zebhola kunye ne-butterfly valves zisetyenziswa ngokuqhelekileyo.

Ukusuka kubukhulu be-12”ukuya ku-24”(DN300-DN600), iivalvu zebhabhathane zisetyenziswa ngokuqhelekileyo kuyilo olungabizi kakhulu. Iivalve zebhola zibiza kakhulu phakathi kwe-12”-24” (DN300-DN600)

Ukusuka kubukhulu be-24 "ukuya kwi-100" (DN600-DN2500), iivalve zebhabhathane lolona khetho lulungileyo kwimibhobho yobungakanani obukhulu. Iivalvu zebhabhathane zineengenelo zokuqaqambisa ezicacileyo kwibala lobungakanani obukhulu kumzimba walo oxineneyo, utshintsho lwemathiriyeli ebhetyebhetye kumalungu. Iivalve ze-Butterfly ziguquguquka kwizinto zombini zomzimba kunye ne-disc, inokuhluka kwi-Ductile iron GGG40 / GGG50, i-WCB, i-Stainless Steel 316L, i-Duplex Stainless steel 4A, i-5A, nakwi-Inconel625/825. Ukutywinwa kweevalvu zeButterfly nako kuyabhetyebhetye. Iyakwazi ukuqina itywina ngezinto EPDM, NBR, PTFE ect, kwaye kwakhona inokuba intsimbi ehlaliswe izinto SS304, SS316, Stellite, duplex stainless 2205. 2507. (UNS31803 & UNS32750) .

I-DN700 i-vlaves yeButterfly egxininisiweyo

Uxinzelelo loxinzelelo:

1. Ukusetyenziswa koxinzelelo oluphantsi njenge-PN6, i-PN10, i-PN25, zombini ii-valve ze-butterfly kunye neebhola zebhola ziyasebenza.
2. Uxinzelelo oluphezulu olusuka kwi-PN40 ukuya kwi-PN250 (iKlasi ye-300LBS ukuya kwiklasi ye-1500LBS), ii-valve zeBhola zinokukhuphisana ne-butterfly valves, idizayini ye-valve yebhola ilula kwaye ifana ne-valve yebhola ephantsi. Nje ukuba nomzimba kunye noyilo lwe-2-pcs, ibhola enye njenge-trim, i-PTFE njengetywina. Kodwa iivalve zebhabhathane zidinga i-offset ephindwe kabini kunye ne-triple offset ukuphucula inqanaba loxinzelelo kunye noyilo lwe-fiple offset luntsokothile kakhulu kuneevalve zebhabhathane ezinoxinzelelo oluphantsi. Kwaye ibe yimfuno yayo entsonkothileyo kunye noyilo oluchanekileyo, ixabiso libiza kakhulu kuneevalvu zebhola.
3. Kuluhlu oluphezulu loxinzelelo oluvela kwi-2500LBS-4500LBS, iivalve zebhola zinokusebenza kakuhle, kodwa i-butterfly valves ayisebenzi ngokupheleleyo ngolu hlobo loxinzelelo.

Ukwehla koxinzelelo:

Iivalve zebhola zisebenzisa ibhola ngaphakathi ukulawula ukuvula nokuvala, Xa ibhola livula, amanzi / aphakathi adlula kwi-bore ye-valve yebhola ngokugcwele ngaphandle komqobo, ukuhla koxinzelelo kuphantsi kakhulu.

Iivalve zebhabhathane zisebenzisa idiski ukulawula indawo evulekileyo nokuvala. Xa i-disc ikwindawo evulekileyo, amanzi / aphakathi adlula kwi-bore ye-butterfly valves, i-disc ifakwe kwi-flow channel, ebangela ukuba umthamo omncinci wamanzi / ophakathi kwindawo yokuphuma xa kuthelekiswa nenxalenye yokungena. Iivalvu zebhabhathane zibangela ukuhla koxinzelelo olukhulu kuneevalvu zebhola

Ukutswina

Ngenxa yokuba i-disc yevalve yebhabhathane ibekwe phakathi kwendlela yokuhamba, ipesenti evulekileyo / evaliweyo kunye nesantya sokuhamba silingana ne-liner, eyongeza iivalve zebhabhathane omnye umsebenzi wokuthontsiza xa kuthelekiswa neevalvu zebhola. Kodwa kwipesenteji ephantsi yokuvula, ukuhamba kwamanzi akulingani kwaye kubangele ukunxitywa kwetywina. Iivalvu zebhabhathane ezisebenza ngokungqongqo kakhulu kwaye azicetywanga xa uxinzelelo/ulawulo lokuhamba lufuna kwinkqubo yemibhobho.

Iivalvu zebhola zenzelwe kuphela uku-off kwaye ngaphandle kokusebenza kwe-throttling.

Ihagu kunye nokugcinwa

Xa umbhobho ufuna ukucocwa, iivalve zebhola lolona khetho lulungileyo, ivuleke ngokupheleleyo kwaye ivumela ihagu ukuba igqithe ukuze ikhuphe ukungcola okusembhobho, ngakumbi emva kokusebenza ixesha elide lombhobho.t.
