Ivalvu yeButterfly ethambileyo
Ivalvu yeButterfly eQinileyo
Izitywino eziqinileyo zenziwe ngesinyithi, njengee-gaskets zesinyithi, iiringi zesinyithi, njl.njl., kwaye ukutywinwa kufezekiswa ngokungqubana phakathi kweesinyithi. Ke ngoko, ukusebenza kokutywina kuphantsi kakhulu, kodwa ivalvu yethu ye-ZFA valve ene-multi-layer hard seal triple offset butterfly valve yethu ayinakuvuza nakancinci. Izitywino ezithambileyo zenziwe ngezinto ezithambileyo, ezifana nerabha, i-PTFE, njl.njl. Kwezinye izixhobo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, ezingenakho ukuhlangabezana neemfuno zenkqubo, iivalvu zebhabhathane ezivaliweyo eziqinileyo zinokusombulula ingxaki.
Umahluko phakathi kweevalvu zebhabhathane ezitywiniweyo kunye neevalvu zebhabhathane ezitywiniweyo ezithambileyo:
1. Umahluko kwisakhiwo: Iivalvu zebhabhathane ezitywiniweyo ezithambileyo ikakhulu ziivalvu zebhabhathane ezisezantsi kwayeiivalvu zebhabhathane ezingaqhelekanga ezimbini, ngelixa iivalvu zebhabhathane ezitywiniweyo kakhulu ziziivaluvu zebhabhathane ezingaqhelekanga kwayeiivalvu zebhabhathane ezingaqhelekanga ezintathu.
2. Ukumelana nobushushu: Itywina elithambileyo lisetyenziswa kwindawo yobushushu obuqhelekileyo, iRubber kwi -20℃~+120℃, iPTFE kwi -25℃~+150℃. Itywina eliqinileyo lingasetyenziswa kwindawo yobushushu obuphantsi, kubushushu obuqhelekileyo, kubushushu obuphezulu nakwezinye iindawo, umzimba wevalvu yebhabhathane yeLCB kwi -29°C -+180°C, umzimba wevalvu yebhabhathane yeWCB ≤425°C, umzimba wevalvu yebhabhathane yentsimbi engagqwali ≤600°C.
3. Uxinzelelo: Itywina elithambileyo, uxinzelelo oluphantsi-uxinzelelo oluqhelekileyo lwe-PN6-PN25, itywina eliqinileyo lingasetyenziswa nakwiimeko zoxinzelelo oluphakathi noluphezulu ezifana ne-PN40 nangaphezulu.
4. Ukusebenza kokutywina: Ivalvu yebhabhathane ethambileyo kunye nevalvu yebhabhathane eqinileyo ephindwe kathathu zisebenza ngcono ekutywineni. Ivalvu yebhabhathane engaqhelekanga kathathu inokugcina ukutywina okungenalo ukuvuza okuhle kwindawo enoxinzelelo oluphezulu kunye nobushushu obuphezulu. Nangona kunjalo, kunzima kwiivalvu zebhabhathane eziqhelekileyo ezivaliweyo ukufezekisa ukungavuzi.
5. Ixesha lokusebenza: Iivalvu zebhabhathane ezitywiniweyo zinokwaluphala kwaye ziguge, kwaye ixesha lokusebenza kwazo kulindeleke ukuba libe lifutshane. Iivalvu zebhabhathane ezitywiniweyo zinobomi obude bokusebenza.
Ngenxa yeempawu ezingasentla, ivalvu yebhabhathane esembindini ifanelekile ukusetyenziswa emanzini acocekileyo, amanzi amdaka, amanzi olwandle, amanzi anetyuwa, umphunga, igesi yendalo, ukutya, amayeza, iimveliso zepetroli, ukuvulwa nokuvalwa kwemibhobho yokukhupha umoya nothuli kwicala eliphambili, kunye nee-asidi ezahlukeneyo kubushushu obuqhelekileyo, uxinzelelo kunye neemeko zemidiya ezingonakalisiyo. I-alkali kunye neminye imibhobho ifuna ukuvalwa ngokupheleleyo, uvavanyo lokuvuza kwegesi olungekho, kunye nobushushu bokusebenza obuyi--10~150℃. Ivalvu yebhabhathane evalwe ngokuqinileyo ifanelekile kwiimeko ezinobushushu obuphezulu, uxinzelelo oluphezulu kunye nemidiya ebolileyo, ezifana nezixhobo zokulawula kunye nokubhoboza kwimibhobho yeoyile, igesi, iasidi kunye ne-alkali efana nokufudumeza idolophu, unikezelo lwegesi, unikezelo lwamanzi, ipetroli, i-petrochemical, ishishini leekhemikhali, i-metallurgy, kunye namandla ombane. kunye neminye imimandla. Iyindawo elungileyo yokutshintsha iivalvu zesango kunye neevalvu zeglobe.
