Ivalve yebhola, ilungu lokuvula kunye nokuvala (ibhola) liqhutywa yi-valve stem kwaye ijikeleze i-axis yevalve yebhola.Ingasetyenziselwa ukulawula ulwelo kunye nolawulo.Phakathi kwazo, ivalve yebhola etywiniweyo enobume be-V inamandla aqinileyo okucheba phakathi kondoqo webhola omilise u-V kunye nesihlalo sevalve yentsimbi ye-hard alloy surfacing, elungele ngokukodwa imicu kunye namasuntswana aqinileyo.njl. phakathi.Ivalve yebhola ye-multi-port kwi-pipeline ayikwazi ukulawula ngokuguquguqukayo kuphela ukudibanisa, ukuguqulwa, kunye nokutshintshwa kwendlela ehamba ngayo ye-medium, kodwa inokuvala nayiphi na itshaneli kwaye idibanise amanye amajelo amabini.Olu hlobo lwevalve kufuneka lufakwe ngokubanzi ngokuthe tye kumbhobho.Ivalve yebhola yohlulwe ibe: ivalve yebhola yepneumatic, ivalve yebhola yombane, ivalve yebhola yezandla ngokwendlela yokuqhuba.

Iimpawu zevalve yebhola:

1. Ukunganxibi;kuba undoqo wevalve yevalve yebhola etywiniweyo yintsimbi yokutshiza,

Umsesane wokutywina wenziwa ngentsimbi ye-alloy engaphezulu, ngoko ke ivalve yebhola etywiniweyo ayisayi kuvelisa ukunxiba kakhulu xa ilayitiwe kwaye icinyiwe.(Ubunzima bayo buyi-65-70):

Okwesibini, ukusebenza kokutywina kulungile;ngenxa yokuba ukutywinwa kwevalve yebhola etywinwe kalukhuni kumhlaba owenziweyo, ayinakusetyenziswa de undoqo wevalve kunye neringi yokutywina ifaniswe.Ngoko ukusebenza kwakhe kokutywinwa kuthembekile.

Okwesithathu, iswitshi ilula;ngenxa yokuba emazantsi eringi yokutywina yevalve yebhola etywiniweyo ithatha intwasahlobo ukubamba ikhonkco lokutywina kunye nesiseko sevalve ngokuqinileyo kunye, iswitshi ilula kakhulu xa amandla angaphandle edlula ukulayisha kwangaphambili kwentwasahlobo.

4. Ubomi benkonzo ende: Isetyenziswe ngokubanzi kwipetroleum, kwishishini lemichiza, ekuveliseni amandla, ekwenzeni iphepha, amandla eathom, inqwelomoya, imijukujelwa namanye amasebe, kwanobomi babantu bemihla ngemihla.

I-valve yebhola ye-pneumatic inesakhiwo esilula kunye nesicatshulwa, ukutywinwa okuthembekileyo kunye nokugcinwa okufanelekileyo.Indawo yokutywina kunye ne-spherical surface ihlala ivaliweyo, engenakunqandwa lula yi-medium, kwaye kulula ukuyisebenzisa nokugcina.Ifanelekile kumajelo asebenzayo ngokubanzi njengamanzi, i-solvent, i-asidi kunye negesi yendalo.Isetyenziselwa ikakhulu ukusika Okanye ukudibanisa okuphakathi kumbhobho, kwaye ingasetyenziselwa ukulawulwa kwamanzi kunye nokulawula.

Xa kuthelekiswa nezinye iindidi zeevalvu, iivalve zebhola yepneumatic zine-angular stroke output torque, ukuvulwa okukhawulezayo, okuzinzileyo nokuthembekileyo, usetyenziso olubanzi, kunye nezi zibonelelo zilandelayo:

1. I-thrust bearing inciphisa i-torque ye-friction ye-valve stem, enokwenza i-valve stem isebenze kakuhle kwaye iguquguquke.

2. Umsebenzi we-Anti-static: I-spring ibekwe phakathi kwebhola, i-valve stem kunye nomzimba we-valve, onokuthumela ngaphandle umbane osisigxina owenziwe ngexesha lokutshintsha.

3. Ngenxa yezinto ezilungileyo zokuzithambisa ze-PTFE kunye nezinye izinto, ukulahleka kwe-friction kunye nebhola kuncinci, ngoko ke ubomi benkonzo yevalve yebhola ye-pneumatic bude.

4. Ukuxhathisa ulwelo oluncinci: Ivalve yebhola yepneumatic yenye yeentlobo ezincinci zokuxhathisa ulwelo phakathi kwazo zonke iindidi zevalvu.Nditsho nevalve yebhola yepneumatic encitshisiweyo, ukuxhathisa kwayo kulwelo kuncinci kakhulu.

5. Ukutywinwa kwe-valve stem ethembekileyo: Ekubeni i-valve stem ijikeleza kuphela kwaye ayihambi phezulu kwaye iphantsi, ukupakisha isitywina se-valve stem akulula ukuba sonakaliswe, kwaye amandla okutywinwa ayanda ngokunyuka koxinzelelo oluphakathi.

6. Isihlalo sevalve sinomsebenzi wokutywina kakuhle: ikhonkco lokutywina elenziwe ngezinto ezilastiki ezifana ne-PTFE kulula ukutywinwa kwisakhiwo, kunye nokukwazi ukutywinwa kwe-valve yebhola ye-pneumatic kwandisa ngokunyuka koxinzelelo oluphakathi.

7. Ukuxhathisa ulwelo kuncinci, kwaye ivalve yebhola egcweleyo ayinakuchasana nokuhamba.

8. Isakhiwo esilula, ubungakanani obuncinci kunye nobunzima obulula.

9. Iqinile kwaye ithembekile.Ineendawo ezimbini zokutywina, kunye nezixhobo zokutywina zevalve yebhola zisetyenziswa ngokubanzi kwiiplastiki ezahlukeneyo, ezinomsebenzi wokutywina kwaye zinokufikelela ukutywinwa.Ikwasetyenziswa ngokubanzi kwiinkqubo zevacuum.

10. Ukusebenza okulula, ukuvulwa ngokukhawuleza kunye nokuvala, i-valve yebhola idinga kuphela ukujikeleza i-90 ° ukusuka ekuvuleni ngokupheleleyo ukuya ekuvaleni ngokupheleleyo, okulungele ukulawula umgama omde.

11. Kulula ukuyigcina, i-valve yebhola inesakhiwo esilula, indandatho yokutywina iyashukunyiswa ngokuqhelekileyo, kwaye ikulungele ngakumbi ukuchithwa nokutshintsha.

12. Xa ivuliwe ngokupheleleyo okanye ivalwe ngokupheleleyo, iindawo zokutywina zebhola kunye nesihlalo sevalve zibekwe zodwa ukusuka kwindawo ephakathi, kwaye xa i-medium idlula, ayiyi kubangela ukukhukuliseka kwendawo yokutywinwa kwevalve.

13. Uluhlu olubanzi lwezicelo, ububanzi ukusuka kwincinci ukuya kwiimilimitha ezininzi, ezinkulu ukuya kwiimitha ezininzi, kwaye zingasetyenziswa ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu.

14. Ngenxa yokuba i-valve yebhola inepropathi yokucima ngexesha lokuvula kunye nokuvala inkqubo, ingasetyenziselwa phakathi kunye neengqungquthela eziqinileyo ezimisiwe.

15. Ukuchaneka okuphezulu kokusebenza kunye neendleko eziphezulu.Ayifanelekanga ukusetyenziswa kwiqondo lokushisa eliphezulu.Ukuba kukho ukungcola kwipayipi, kulula ukuvalelwa ngokungcola, okubangela ukuba i-valve ayikwazi ukuvulwa.
