Indlela yokukhetha okulungileyomanual butterfly valveimpahla yokutywina?
Iivalve zebhabhathane ezenziwe ngesandla luhlobo oluqhelekileyo lwesivalo, ikakhulu esetyenziselwa ulawulo lokuhamba kunye nolawulo lolwelo kwimibhobho. Izinto zokutywina zidlala indima ebalulekileyo ekusebenzeni kokutywinwa kwevalve ye-butterfly manual, ngoko xa ukhetha ivalve, kuyimfuneko ukuqonda ukusebenza kunye noluhlu lwesicelo sezinto zokutywina ezahlukeneyo ukuze kukhethwe into efanelekileyo yokutywina i-butterfly valve.
1. Irabha yeFluorine (FKM)
Irabha yeFluorine inokumelana neekhemikhali ezilungileyo kunye neempawu zobushushu obuphezulu, kwaye inokwenza isitywina esingcono kumaqondo obushushu aphantsi. Ifanelekile kwimidiya engamanzi equlethe i-asidi, i-alkalis, i-oyile kunye ne-oxidants. Nangona kunjalo, izinto zokutywina irabha ye-fluorine zibiza kakhulu kwaye ayifanelekanga ukusetyenziswa phantsi kweemeko zomphunga.
2.NBR irabha
Izibonelelo ze-NBR zokutywinwa kwerubha izinto zixabiso eliphantsi kunye nokusebenza okuzinzile. Nangona kunjalo, ukumelana kwayo nobushushu obuphezulu, ukuxhathisa kwe-oxidation kunye nokuxhathisa ukubola kubuthathaka, ngokuyintloko ilungele izicelo ezincinci kunye nobungakanani obuphakathi obuphantsi obufana namanzi, i-oyile, umphunga kunye ne-metal brine.
3. Irabha yeNeoprene (CR)
I-Neoprene inokumelana ne-oyile elungileyo kunye neempawu zokuchasana nokuguga, kwaye ingasetyenziswa kuluhlu olubanzi lobushushu. Ifanele i-oyile, ikhabhoni eneklorini kunye nezinye izinyibilikisi ezikwimeko ephakathi, kodwa ayifanelekanga kwindawo yobushushu obuphezulu bomphunga.
4. Irabha yeSilicone (Si)
Izinto zokutywina irabha ye-Silicone inokumelana nobushushu obuphezulu, ukuxhathisa kwimitha kunye nokothuka kunye nokumelana nokuqhekeka, ilungele ukutywinwa kwindawo yobushushu obuphezulu. Nangona kunjalo, ukuqina kunye nokumelana nokukrazula kwerabha ye-silicone kwindawo yobushushu obuphantsi kumbi kakhulu.
5.PTFE
I-advanteji ye-PTFE kukuba inokumelana ne-corrosion elungileyo kunye nokumelana nobushushu obuphezulu, kodwa ukuqina kwayo kunye nokumelana nokunxiba akubi, kwaye ayifanelekanga ukusetyenziswa kwiindawo ezinolwelo kunye namazinga okuhamba ngokukhawuleza.
6. I-Polyimide (PI)
I-Polyimide luhlobo lobushushu obuphezulu kunye nezixhobo zeplastiki ezinamandla aphezulu, kunye nokusebenza kakuhle kwiqondo eliphezulu lobushushu kunye nokumelana nokugqwesa kweekhemikhali, ezifanelekileyo kubushushu obuphezulu kunye noxinzelelo oluphezulu njengesixhobo sokutywina.
Xa ukhetha izinto zokutywinwa kwevalve yebhabhathane, kuyimfuneko ukuqwalasela ubume bolwelo olukwimibhobho, izinga lokuqukuqela, ubushushu, uxinzelelo kunye nezinye izinto, kwaye ukhethe izinto ezifanelekileyo zokutywina ukuqinisekisa ukusebenza okuzinzileyo kunye nokusebenza ngokukhuselekileyo kwencwadi. ivelufa butterfly. Kubalulekile ukuba uqaphele ukuba ngaphambi kokusebenzisa nayiphi na into yokutywina, kuyacetyiswa ukuba uvavanye ukuqina kwayo kunye nokusebenza kokutywinwa kwindawo ekujoliswe kuyo yamanzi.
