I-valve yebhola yepulasitiki yavela ku-valve yepulaki. Ingxenye yayo yokuvula neyokuvala iyindilinga, esebenzisa i-sphere ukuzungezisa ama-degree angama-90 eduze kwe-axis yesiqu se-valve ukufeza injongo yokuvula nokuvala. I-valve yebhola yepulasitiki ilungele ukucatshangelwa kwenqubo yokuthutha nge-corrosive medium. Ngokusho kwezinto ezahlukene, izinga lokushisa lokusebenza yi-PVC 0℃～50℃, C-I-PVC0℃～90℃, PP -20℃～100℃, PVDF -20℃～100℃ . I-valve yebhola lepulasitiki inokumelana nokugqwala okuhle kakhulu. Indandatho yokuvala yamukela i-EPDM ne-FKM; inokumelana nokugqwala okuhle kakhulu futhi yandisa impilo yesevisi. Ukujikeleza okuguquguqukayo futhi kulula ukuyisebenzisa. I-valve yebhola yepulasitiki I-valve yebhola ebalulekile inamaphuzu ambalwa okuvuza, amandla aphezulu, futhi uhlobo lokuxhumana lwe-valve yebhola kulula ukuhlanganisa nokuhlakazwa.

I-valve yebhola yepulasitiki ayilula nje kuphela ngesakhiwo, inhle ekusebenzeni kokuvala, kodwa futhi incane ngosayizi, ilula ngesisindo, iphansi ngokusetshenziswa kwezinto ezibonakalayo, isayizi encane yokufaka, futhi incane ekushayeleni i-torque ngaphakathi kobubanzi obuthile bokuzisholo. Kulula ukuyisebenzisa futhi kulula ukuyifinyelela ukuvulwa nokuvala ngokushesha. Enye yezinhlobo zama-valve ezikhula ngokushesha eminyakeni eyishumi edlule. Ikakhulukazi emazweni athuthukile njengaseMelika, eJapane, eJalimane, eFrance, e-Italy, eNtshonalanga, naseBrithani, ukusetshenziswa kwamavalvu ebhola kukhulu kakhulu, futhi izinhlobonhlobo nenani elisetshenziswayo zisakhula.

Isimiso sokusebenza se-valve yebhola lepulasitiki ukwenza i-valve ivuleke noma ivinjwe ngokuzungezisa isiqu se-valve. I-switch iyaphatheka, incane ngosayizi, inokwethenjelwa ekubekweni uphawu, ilula ngesakhiwo futhi ilungele ukulungiswa. Indawo yokuvala kanye nendawo eyindilinga kuvame ukuba sesimweni esivaliwe futhi ayiguguleka kalula yi-medium. Isetshenziswa kabanzi ezimbonini ezahlukahlukene.

I-valve yebhola wuhlobo olusha lwei-valveosekusetshenziswe kabanzi eminyakeni yamuva. Inezinzuzo ezilandelayo:

1. Ukumelana noketshezi kuncane, futhi i-coefficient yayo yokumelana ilingana nengxenye yepayipi yobude obufanayo.

2. Isakhiwo esilula, usayizi omncane kanye nesisindo esincane.

3. Iqinile futhi ithembekile. Njengamanje, indawo yokuvala uphawu ye-valve yebhola isetshenziswa kabanzi kumapulasitiki anomsebenzi omuhle wokuvala, futhi isetshenziswe kabanzi ezinhlelweni ze-vacuum.

4. Ukusebenza okulula, ukuvulwa okusheshayo nokuvala, udinga kuphela ukuzungeza i-90 ° kusukela ekuvuleni ngokugcwele kuya kuvaliwe ngokugcwele, okulungele ukulawula okude.

5. Ukugcinwa okulula, isakhiwo esilula se-i-valve yebhola, indandatho evala uphawu ngokuvamile iyagudluka, kulula ukuyiqaqa bese uyishintsha.

6. Uma ivuleke ngokugcwele noma ivaleke ngokugcwele, indawo yokuvala yebhola kanye nesihlalo sevalvu kuyahlukaniswa phakathi nendawo, futhi okuphakathi ngeke kubangele ukuguguleka kwendawo yokuvala ivalvu lapho okuphakathi kudlula.

7. Inezinhlobonhlobo zezinhlelo zokusebenza, ezinobubanzi obusuka kumamilimitha ambalwa kuya kumamitha ambalwa, futhi ingasetshenziswa kusuka ku-vacuum ephezulu kuya ekucindezelweni okuphezulu.
