Ungayikhetha njani ivalve ethembekileyo?

Ukukhetha ukuthembekaIbhotile yebhabhathaneIfuna ukuqwalaselwa ngokupheleleyo kwesakhiwo, isixhobo, kunye neemeko zokusebenza.

Uhlobo lolwakhiwo sisiseko sokukhetha ivali yebhabhathane. Uxinzelelo olusezantsi kunye neemeko zobushushu zegumbi (ezinje ngeenkqubo zokubonelela ngamanzi) zilungele i-valves yebhabhathane, enesakhiwo esilula kunye neendleko eziphantsi; Iivalves eziphindwe kabini ze-eccentric zinokusetyenziswa kwiimeko eziphakathi kunye neemeko eziphakathi zobushushu (ezinje ngemibhobho yokutsala edolophini), ngentsebenzo engcono kune-valve eziphakathi kwe-valve; Iivila ezintathu zebhabhathane kufuneka zikhethwe kubushushu obuphezulu kunye neemeko eziphezulu zokusetyenziswa koxinzelelo (ezinje nge-Steam, umbhobho we-oyile kunye noxinzelelo lwerhasi), i-pipeding yegesi exhaphakileyo, inobomi obude. Umzekelo, xa uhambisa imithombo yeendaba ebomvu kwimibhobho yekhemikhali, i-316 ye-316 ye-316 ye-valve ye-valve ye-valve ye-Ptfey + ye-PTFA yokutyhubela iverubhu emithathu ye-eccentric anokuxhathisa i-chimical slosion.

Ukukhetha izinto ezibonakalayo kuchaphazela ngqo ukuqina kweI-Butterfly Valves. Izixhobo zomzimba zeValve kufuneka zingqinelane noxinzelelo lokusebenza: I-Iron ye-Iron Valve inokusetyenziswa kuxinzelelo oluphantsi kunye neemeko zobushushu zegumbi (ezinje ngenkqubo yamanzi emondo); I-carbon yensimbi okanye imizimba yentsimbi engenasitayile kufuneka ikhethwe kwiindawo eziphakathi nephezulu zoxinzelelo (ezinje ngemibhobho yeoyile); Iimeko zoncedo ezinamandla (ezinje ngamanzi aselwandle) zifuna izixhobo ezizodwa. Ngokwemithombo yokutywina, imithombo yeendaba engaqhelekanga (njengamanzi nomoya) ilungele ukutywinwa kwerabha; Imithombo yeendaba yekhemikhali (ezinje ngee-asidi kunye neziseko) kufuneka zitywinwe ngePolytetrafliookeOothlOothylene (PTFE); Ukutywinwa kwensimbi (njengentsimbi engenasitayile okanye isabelo esinzima) kufuneka isetyenziswe kwiqondo lobushushu ephezulu kunye nemeko ephezulu yoxinzelelo.

Ukulungelelaniswa kwemeko yokusebenza yeyona nto iphambiliIbhotile yebhabhathaneukhetho. Kuyimfuneko ukucacisa uhlobo lwe-medium (igesi / irhasi / i-paricle equkayo), uluhlu lobushushu (-196 ℃ ukuya kwi-600 ℃), iimfuno zoxinzelelo (uhlobo lokutshintsha). Umzekelo, ukuba isityalo sonyango lokuntywila kufuneka sikhuphe isixa esikhulu sokuntywila, kufuneka sikhethe umzimba we-valve ye-valve ye-valve nge-DN300 okanye ngaphezulu kunye ne-valve evaliweyo yebhabhathane; Xa udlulisa imithombo yeendaba ye-viscous efana neSiraphu kwizityalo zokutya, i-eccentric abterricly valves kufuneka isetyenziselwe ukunciphisa ukunganyangeki.
