I-valve yebhola yethusi, ilungu elivulayo nelivalayo (ibhola) liqhutshwa isiqu se-valve futhi lizungeza i-axis ye-valve yebhola.Ingasetshenziselwa futhi ukulawula nokulawula uketshezi.Phakathi kwazo, i-valve yebhola eqinile emise okwe-V evalwe ngokuqinile inamandla aqinile okugunda phakathi kwengqikithi yebhola emise okuka-V kanye nesihlalo sevalvu yensimbi ye-hard alloy surface, elungele ngokukhethekile imicu nezinhlayiya ezincane eziqinile.njll. medium.I-valve yebhola enamachweba amaningi epayipini ayikwazi nje kuphela ukulawula ngokuguquguqukayo ukuhlangana, ukuphambukisa, kanye nokushintsha kwendlela yokuhamba kwendawo ephakathi nendawo, kodwa futhi ingavala noma isiphi isiteshi futhi ixhume amanye amashaneli amabili.Lolu hlobo lwe-valve ngokuvamile kufanele lufakwe ngokuvundlile epayipini.I-valve yebhola ihlukaniswe: i-valve yebhola ye-pneumatic, i-valve yebhola kagesi, i-valve yebhola ye-manual ngokusho kwendlela yokushayela.

Izici ze-Ball valve:
1. Ingagugi;ngoba i-valve core of the hard-sealedI-valve yebhola yethusii-alloy steel spray welding,
Indandatho yokuvala yenziwe ngensimbi ye-alloy engaphezulu, ngakho-ke i-valve yebhola evalwe kanzima ngeke ikhiqize ukuguga okukhulu uma ivulwa futhi icishwa.(Isici sokuqina kwayo yi-65-70):
Okwesibili, ukusebenza kokubekwa uphawu kuhle;ngenxa yokuthi ukuvalwa kwe-valve yebhola evalwe kanzima kugaywe ngokwenziwa, angeke kusetshenziswe kuze kufaniswe umongo we-valve nendandatho yokuvala.Ngakho ukusebenza kwakhe kokubekwa uphawu kunokwethenjelwa.
Okwesithathu, inkinobho ilula;ngenxa yokuthi iphansi lendandatho yokuvala ye-valve yebhola evalwe kanzima ithatha isiphethu ukuze ibambe indandatho yokuvala kanye nomgogodla we-valve ndawonye, ​​​​iswishi ilula kakhulu lapho amandla angaphandle edlula ukulayisha kuqala kwentwasahlobo.
4. Impilo ende yesevisi: Isetshenziswe kakhulu kuphethiloli, embonini yamakhemikhali, ekuphehleni amandla, ekwenzeni iphepha, amandla e-athomu, ezondiza, amarokhethi neminye iminyango, kanye nempilo yabantu yansuku zonke.
I-valve yebhola ye-pneumatic inesakhiwo esilula futhi esihlangene, ukubekwa uphawu okuthembekile nokugcinwa okulula.Indawo yokubeka uphawu kanye ne-spherical surface ihlala isesimweni esivaliwe, esingaqedwa kalula yi-medium, futhi kulula ukuyisebenzisa nokuyigcina.Ilungele imidiya evamile yokusebenza njengamanzi, i-solvent, i-asidi negesi yemvelo.Isetshenziselwa ukusika noma ukuxhuma i-medium epayipini, futhi ingasetshenziselwa ukulawula nokulawula uketshezi.
Uma kuqhathaniswa nezinye izinhlobo zama-valve, ama-valve ebhola womoya ane-angular stroke output torque, ukuvulwa okusheshayo, okuzinzile nokuthembekile, ukusetshenziswa okubanzi, kanye nezinzuzo ezilandelayo:
1. I-thrust bear inciphisa i-torque yokungqubuzana kwesiqu se-valve, engenza isiqu se-valve sisebenze kahle futhi siguquguquke.
2. Umsebenzi we-Anti-static: Isiphethu sisethwe phakathi kwebhola, isiqu se-valve kanye nomzimba we-valve, ongakhipha ugesi omile okhiqizwe phakathi nenqubo yokushintsha.
3. Ngenxa yezakhiwo ezinhle zokuzigcoba ze-PTFE nezinye izinto, ukulahlekelwa ukungqubuzana nebhola kuncane, ngakho-ke impilo yesevisi ye-valve yebhola yomoya yinde.
4. Ukumelana noketshezi oluncane: I-valve yebhola yomoya ingenye yezinhlobo ezincane zokumelana noketshezi phakathi kwazo zonke izigaba zamavalvu.Ngisho ne-valve yebhola yomoya encishisiwe enobubanzi, ukumelana kwayo noketshezi kuncane kakhulu.
5. I-valve stem seal enokwethenjelwa: Njengoba isiqu se-valve sijikeleza kuphela futhi asihambisi phezulu naphansi, uphawu lokupakisha lwe-valve stem akulula ukulinyazwa, futhi ikhono lokuvala liyakhula ngokunyuka kokucindezela okuphakathi.
6. Isihlalo se-valve sinomsebenzi omuhle wokuvala: indandatho yokuvala eyenziwe ngezinto ezinwebekayo ezifana ne-PTFE kulula ukuyivala ngesakhiwo, futhi ikhono lokuvala i-valve yebhola yomoya liyakhula ngokunyuka kwengcindezi ephakathi.
7. Ukumelana noketshezi kuncane, futhi i-valve yebhola egcwele ngokugcwele ayinakho ukumelana nokugeleza.
8. Isakhiwo esilula, usayizi omncane nesisindo esincane.
9. Iqinile futhi inokwethenjelwa.Inezindawo ezimbili zokuvala, futhi izinto ezingaphezulu zokuvala ze-valve yebhola zisetshenziswa kakhulu kumapulasitiki ahlukahlukene, anokusebenza okuhle kokuvala futhi angafinyelela ukubekwa uphawu.Ibuye isetshenziswe kabanzi kumasistimu we-vacuum.
10. Ukusebenza okulula, ukuvulwa okusheshayo nokuvala, i-valve yebhola idinga kuphela ukujikeleza i-90 ° kusukela ekuvuleni ngokugcwele kuya ekuvaleni ngokugcwele, okulungele ukulawula ibanga elide.
11. Kulula ukuyigcina, i-valve yebhola inesakhiwo esilula, indandatho yokuvala ngokuvamile iyasuswa, futhi kulula kakhulu ukuyihlakaza nokufaka esikhundleni.
12. Uma ivuliwe ngokugcwele noma ivalwe ngokugcwele, izindawo zokuvala zebhola kanye nesihlalo se-valve zihlukaniswa phakathi nendawo, futhi lapho okuphakathi kudlula, ngeke kubangele ukuguguleka kwendawo yokuvala i-valve.
13. Uhlu olubanzi lwezinhlelo zokusebenza, ububanzi obusukela kokuncane kuya kumamilimitha amaningana, olukhulu kuya kumamitha amaningana, futhi lungasetshenziswa kusuka ku-vacuum ephezulu kuya kungcindezi ephezulu.
14. Ngenxa yokuthi i-valve yebhola inempahla yokusula ngesikhathi sokuvula nokuvala, ingasetshenziswa phakathi nendawo enezinhlayiya eziqinile ezimisiwe.
15. Ukunemba okuphezulu kokucubungula kanye nezindleko eziphezulu.Ayifanele ukusetshenziswa ekushiseni okuphezulu.Uma kukhona ukungcola epayipini, kulula ukuvinjelwa ukungcola, okuholela ekutheni i-valve ayikwazi ukuvulwa.
