Ii-valve yebhola lepulasitikiyavela 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 ezihlukahlukene, izinga lokushisa lokusebenza liyiI-PVC0℃～50℃, C-PVC 0℃～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 njenge-United States, Japan, Germany, France, Italy, West, neBrithani, ukusetshenziswaama-valve ebholainkulu kakhulu, futhi izinhlobo nenani elisetshenziswayo kusakhula.

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 lwe-valve olusetshenziswe 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-valve yebhola, indandatho yokuvala ngokuvamile iyasuswa, kulula ukuyihlakaza nokufaka esikhundleni.

6. Uma ivuliwe ngokugcwele noma ivaliwe ngokugcwele, indawo yokuvala yebhola kanye nesihlalo se-valve ihlukaniswe phakathi nendawo. Lapho okuphakathi kudlula, ngeke kubangele ukuguguleka kwendawo yokuvala i-valve.

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