Ivalve yebhola yeplastiki yavela kwivalve yeplagi.Inxalenye yayo yokuvula kunye nokuvala i-sphere, esebenzisa i-sphere ukujikeleza i-90 degrees malunga ne-axis ye-valve stem ukufezekisa injongo yokuvula nokuvala.Ivalve yebhola yePlastiki ilungele ukucatshulwa kwenkqubo yothutho nge-corrosive medium.Ngokwezixhobo ezahlukeneyo, ubushushu obusebenzayo yiPVC 0℃～50℃, C-I-PVC0℃～90℃, PP -20℃～100℃, PVDF -20℃～100℃ .Ivalve yebhola yeplastiki inokumelana nokugqwesa okugqwesileyo.Umsesane wokutywina wamkela i-EPDM kunye ne-FKM;inokumelana ne-corrosion ebalaseleyo kwaye yandisa ubomi benkonzo.Ukujikeleza okuguquguqukayo kwaye kulula ukuyisebenzisa.Ivalve yebhola yeplastiki Ivalve yebhola edityanisiweyo inamanqaku okuvuza ambalwa, amandla aphezulu, kwaye uhlobo loqhagamshelo lwebhola yevalve kulula ukudibanisa kunye nokuqhaqha.

I-valve yebhola yeplastiki ayilula nje kwisakhiwo, ilungile ekusebenzeni kokutywinwa, kodwa kunye nobukhulu obuncinci, ubunzima bokukhanya, ukusetyenziswa kwezinto eziphathekayo, ubungakanani obuncinci bokufaka, kunye ne-torque encinci yokuqhuba ngaphakathi koluhlu oluthile lwe-diameter.Kulula ukusebenza kwaye kulula ukufezekisa ukuvulwa nokuvala ngokukhawuleza.Olunye lweentlobo zevalvu ezikhula ngokukhawuleza kule minyaka ilishumi idlulileyo.Ingakumbi kumazwe ahambele phambili njengeUnited States, eJapan, eJamani, eFransi, eItali, eNtshona naseBritani, ukusetyenziswa kwezivalo zebhola kuninzi kakhulu, yaye iindidi kunye nobungakanani obusetyenziswayo zisakhula.

Umgaqo osebenzayo wevalve yebhola yeplastiki kukwenza ivalve ingavalwa okanye ivalwe ngokujikeleza isiqu sevalve.Ukutshintsha kuphathekayo, kuncinci ngobukhulu, kunokwethenjelwa ekutywineni, kulula kwisakhiwo kunye nokufanelekileyo ekugcinweni.Umphezulu wokutywina kunye nomphezulu ongqukuva uhlala ukwimeko evaliweyo kwaye awukhukuliswa lula nguwo ophakathi.Isetyenziswa kakhulu kumashishini ahlukeneyo.

Ivalve yebhola luhlobo olutsha lweivalveebisetyenziswa kakhulu kwiminyaka yakutshanje.Inezi ncedo zilandelayo:

1. Ukuxhatshazwa kwamanzi kuncinci, kwaye i-coefficient yayo yokumelana ilingana necandelo lombhobho lobude obufanayo.

2. Isakhiwo esilula, ubungakanani obuncinci kunye nobunzima obulula.

3. Iqinile kwaye ithembekile.Okwangoku, izinto zokutywina ezingaphezulu kwevalve yebhola zisetyenziswa kakhulu kwiiplastiki ezinomsebenzi wokutywina kakuhle, kwaye sele isetyenziswa ngokubanzi kwiinkqubo zokucoca.

4. Ukusebenza ngokufanelekileyo, ukuvulwa ngokukhawuleza kunye nokuvala, kufuneka kuphela ukujikeleza i-90 ° ukusuka ekuvuleni ngokupheleleyo ukuya kuvaliwe ngokupheleleyo, okulungele ukulawula kude.

5. Ulondolozo olulula, ulwakhiwo olulula lweivalve yebhola, umsesane wokutywina uyashukumiseka ngokubanzi, kukulungele ukuqhawuka nokutshintsha.

6. Xa ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo sevalvu zibekwe zodwa ukusuka kwindawo ephakathi, kwaye i-medium ayiyi kubangela ukhukuliseko lomphezulu wokutywina wevalve xa i-medium idlula.

7. Inoluhlu olubanzi lwezicelo, kunye nobubanzi obuvela kwiimilimitha ezimbalwa ukuya kwiimitha ezimbalwa, kwaye ingasetyenziswa ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu.
