Ivalve yebhabhathane yeSitywina ethambileyo
Ivalufa yebhabhathane etywiniweyo enzima
Izitywina ezinzima zenziwe ngesinyithi, njenge-gaskets yensimbi, imisesane yentsimbi, njl., kunye nokutywinwa kufezekiswa ngokungqubuzana phakathi kweentsimbi. Ke ngoko, ukusebenza kokutywina kumbi ngokwentelekiso, kodwa ivalve yethu ye-ZFA eveliswe ivelufa enamaleko amaninzi aqinileyo etywina kathathu ibhabhathane ingakwazi ukuvuza iqanda. Izitywina ezithambileyo zenziwe ngezinto ezilastiki, ezifana nerabha, i-PTFE, njl. njl
Umahluko phakathi kweevalvu zebhabhathane ezitywinwe nzima kunye neevalve zebhabhathane ezitywinwe ngokuthambileyo:
1. Umahluko wesakhiwo: Iivalvu zebhabhathane ezithambileyo zizivalo zebhabhathane ezisembindini kwayeiivalve zebhabhathane eccentric kabini, ngelixa iivalve zebhabhathane eziqinileyo zizivalo zebhabhathane eccentric ubukhulu becala kunyeiivalve zebhabhathane eziphindwe kathathu.
2. Ukumelana nobushushu: Isitywina esithambileyo sisetyenziswa kwindawo yobushushu obuqhelekileyo, iRubber ye -20℃~+120℃, PTFE ye -25℃~+150℃. Ukutywinwa okuqinileyo kungasetyenziselwa ukushisa okuphantsi, ukushisa okuqhelekileyo, ukushisa okuphezulu kunye nezinye iindawo, i-LCB butterfly valve body for -29 ° C -+180 ° C, i-WCB butterfly valve body ≤425 ° C, i-Stainless Steel butterfly valve body ≤600 ° C.
3. Uxinzelelo: Isitywina esithambileyo soxinzelelo oluphantsi-uxinzelelo oluqhelekileyo lwe-PN6-PN25, ukutywinwa okunzima kungasetyenziswa kwiimeko eziphakathi kunye neziphezulu zoxinzelelo ezifana ne-PN40 nangaphezulu.
4. Ukusebenza kokutywina: Ivalve yebhabhathane ethambileyo kunye nevalve yebhabhathane eqinile kathathu yotywino inomsebenzi ongcono wokutywina. Ivalve yebhabhathane ye-eccentric eccentric inokugcina itywina elungileyo elingu-zero kuxinzelelo oluphezulu kunye nendawo yobushushu obuphezulu. Nangona kunjalo, kunzima kwiivalvu zebhabhathane eziqhelekileyo ezitywiniweyo ukuphumeza ukuvuza kweqanda.
5. Ubomi benkonzo: Iivalve ze-butterfly ze-soft-sealing ziyakwazi ukuguga kunye nokugqoka, kwaye ubomi babo benkonzo kulindeleke ukuba bufutshane. Iivalve zebhabhathane ezivaliweyo zinobomi obude benkonzo.
Ngenxa yezi mpawu zingentla, i-valve yebhabhathane ephakathi ilungele ukusetyenziswa kumanzi amatsha, ugutyulo, amanzi olwandle, amanzi etyuwa, umphunga, igesi yendalo, ukutya, iyeza, iimveliso zepetroleum, ukuvulwa kwe-bidirectional kunye nokuvalwa kwemibhobho yokuphuma komoya kunye nokususa uthuli, kunye ne-asidi ezahlukahlukeneyo kwiqondo lokushisa ngokubanzi, uxinzelelo kunye neemeko zeendaba ezingaboliyo. Ialkali kunye neminye imibhobho ifuna ukutywinwa okupheleleyo, uvavanyo lokuvuza kwerhasi engu-zero, kunye nobushushu bokusebenza obuyi-10 ~ 150℃. Ivalve yebhabhathane etywiniweyo ifanelekile kwiimeko ezinobushushu obuphezulu, uxinzelelo oluphezulu kunye nemithombo yeendaba ezonakalisayo, njengokulawula kunye nezixhobo zokuthoba kwioyile, igesi, iasidi kunye nemibhobho yealkali njengokufudumeza kwedolophu, unikezelo lwegesi, unikezelo lwamanzi, i-petroleum, i-petrochemical, ishishini lemichiza, isinyithi, kunye namandla ombane. kunye neminye imimandla. Lutshintsho olulungileyo lweevalvu zesango kunye neglobhu.
