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 kakhulu, kodwa ivalve yethu yeZFA yenziweivelufa yebhabhathane enamaleko amaninzi aqinileyo amathathu eccentricinokufikelela ku-zero ukuvuza.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 ye -29 ° C -+ 180 ° C, i-WCB ≤425 ° C, i-Stainless Steel≤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 etywiniweyo kathathu inomsebenzi ongcono wokutywina.KathathuIvalve yebhabhathane eccentricinokugcina itywina elungileyo lokuvuza kwe-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.
Ngokubhekiselele kwezi mpawu zingasentla, ivalve yebhabhathane ephakathi ilungele ukusetyenziswa kumanzi amatsha, ugutyulo, amanzi olwandle, amanzi anetyuwa, umphunga, igesi yendalo, ukutya, amayeza, iimveliso zepetroleum, ukuvulwa kabini kunye nokuvalwa kwemibhobho yokungena komoya kunye nokususa uthuli, kunye iiasidi ezahlukeneyo kubushushu obuqhelekileyo, uxinzelelo kunye neemeko zemidiya ezingaboliyo.Ialkali kunye neminye imibhobho ifuna ukutywinwa okupheleleyo, uvavanyo lokuvuza kwerhasi engu-zero, kunye nobushushu bokusebenza obuyi-10 ~ 150℃.Ivalve yebhabhathane etywiniweyo ilungele iimeko ezinobushushu obuphezulu, uxinzelelo oluphezulu kunye nemithombo yeendaba ezonakalisayo, njengokulawula kunye nezixhobo zokutshiza kwioyile, igesi, iasidi kunye nemibhobho yealkali njengokufudumeza kwedolophu, ukubonelela ngegesi, unikezelo lwamanzi, i-petroleum, i-petrochemical, ishishini lemichiza, isinyithi, kunye namandla ombane.kunye neminye imimandla.Lutshintsho olulungileyo lweevalvu zesango kunye neglobhu.
