Ivalve yebhola yeplastiki ivele kwivalve yenkanyamba.Iziqwenga zayo ezikwaziyo kunye nokuvala zisetyenziswa njengengqukuva.I-axis yokujikeleza kwevalve yokulimaza i-spherical ijikeleza i-90 degrees ukufezekisa injongo yokuvula nokuvala.Ivalve yebhola yeplastiki ifanelekile ukungenelela kwenkqubo yokudluliselwa kunye neendaba ezitshabalalisayo.Ubushushu bokusebenza kobushushu obusebenzayo bezinto ezahlukeneyo zePVC 0 ℃ ～ 50 ℃, C -PVC 0 ℃ ～ 90 ℃, PP -20 ℃ ～ 100 ℃, PVDF -20 ℃ ～ 100 ℃ ivalve yePlastiki egqwesileyo ℃ 100 ℃ yokumelana nePlastiki.Umsesane wokutywina usebenzisa i-EPDM kunye ne-FKM;inokumelana nokugqwesa okugqwesileyo kwaye yandise ubomi benkonzo.Ukusetyenziswa okuguquguqukayo kunye nokufanelekileyo.Ivalve yebhola yePlastiki ivuza ivalve yebhola, ukomelela okuphezulu, kwaye kulula ukuqhaqha iivalve zebhola ezidibanisayo.
Ivalve yebhola yeplastiki ayinayo kuphela isakhiwo esilula kunye nokusebenza kakuhle kokutywinwa, kodwa inomthamo omncinci, ubunzima obulula, ukusetyenziswa kwezinto ezincinci, ubungakanani obuncinci bokufaka, umzuzu omncinci wokuqhuba kwi-diameter ethile, encinci Enye yeendidi zevalve ezikhawulezayo kwiminyaka elishumi edlulileyo.Ngokukodwa kumazwe aphuhlileyo anjenge-United States, iJapan, iJamani, iFransi, iFransi, iItali, iNtshona, neBritani, ukusetyenziswa kweevalvu zebhola kubanzi kakhulu, kwaye iintlobo zokusetyenziswa kunye nezixa zisakhula.
Umgaqo wokusebenza wevalve yebhola yeplastiki kufuneka uvulwe okanye uvalwe sisikhondo sevalve ejikelezayo.Umtshintshi ulula, ubungakanani buncinci, isitywina sithembekile, isakhiwo silula, ukugcinwa kulula, itywina kunye ne-sphere zihlala zivaliwe, akukho lula ukuchithwa ngamajelo eendaba, kwaye zisetyenziswa ngokubanzi amashishini ahlukeneyo.
Ivalve yebhola luhlobo olutsha lwevalve olusetyenziswe ngokubanzi kwiminyaka yakutshanje.Inezi ncedo zilandelayo:
1. Ukuxhatshazwa kwamanzi kuncinci, kwaye i-coefficients yayo yokumelana nayo ilingana necandelo lombhobho lobude obufanayo.
2. Isakhiwo esilula, ubungakanani obuncinci, ubunzima obulula.
3. Iqinile kwaye ithembekile.Okwangoku, izinto zokutywina zevalve yebhola zisetyenziswa ngokubanzi kwiplastiki kunye nokutywinwa, kwaye zisetyenziswe ngokubanzi kwiinkqubo zokucoca.
4. Kulula ukusebenza, ukuvula ngokukhawuleza kunye nokuvala, nje ukuba inqanaba elipheleleyo ukuya kwinqanaba elipheleleyo, ujikeleze nje i-90 ° ukuququzelela ulawulo lomgama omde.
5. Ukugcinwa okulula, isakhiwo sevalve yebhola elula, isangqa sokutywina sisebenza ngokubanzi, kwaye sikulungele ngakumbi ukuchithwa kunye nokutshintshwa.
6. Xa ivuliwe okanye ivalwe ngokupheleleyo, isigqubuthelo se-sphere kunye nesihlalo sevalve sibekwe sodwa kwindawo ephakathi.Xa i-medium idlula, ayiyi kubangela ukukhukuliseka kwe-valve cover.
7. Umda wesicelo ubanzi, ukusuka kwincinci ukuya kwi-mm ukuya kwiimitha ezimbalwa, ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu.
