Izici zama-valve ebhola.

1. Ingagugi 

Njengoba umnyombo we-valve we-valve yebhola evalwe kanzima iyinsimbi eyingxube efafaziwe futhi indandatho yokuvala iyi-alloy steel overlay welding,i-valve yebhola evalwe kanzimangeke kubangele ukuguga ngokweqile ngesikhathi sokuvula nokuvala. (I-coefficient yokuqina kwayo ingu-65-70):

2. Ukusebenza okuhle kakhulu kokubeka uphawu

Njengoba ukubekwa uphawu kwe-valve yebhola evalwe kanzima kufinyelelwa ngokugaya ngesandla, futhi kungasetshenziswa kuphela uma i-valve core kanye nendandatho yokuvala ihambisana ngokuphelele, ukusebenza kwayo kokuvala kunokwethenjelwa.

3. Ukusebenza okushelelayo

Ngenxa yokuthi iphansi lendandatho yokuvala ye-valve yebhola evalwe kanzima ifakwe isiphethu esiqinisa ngokuqinile indandatho yokuvala kanye nomgogodla we-valve ndawonye, ​​i-valve ingavulwa futhi ivalwe kalula kakhulu lapho amandla angaphandle edlula amandla angaphambi kokuqinisa entwasahlobo.

4. Impilo ende yesevisi

Isetshenziswe kabanzi emikhakheni ehlukahlukene efana ne-petroleum, imboni yamakhemikhali, ukukhiqiza amandla, ukwenza iphepha, amandla e-athomu, ezondiza, amarokhethi, njll., kanye nasezimpilweni zabantu zansuku zonke.

I-valve yebhola ye-pneumatic inesakhiwo esihlangene, ukubekwa uphawu okuthembekile, umklamo olula, nokugcinwa okulula. Indawo evalayo kanye nendawo eyindilinga kuvame ukuba sesimweni esivaliwe, okungenzeka ukuthi singaguguleka yi-medium futhi kulula ukuyisebenzisa nokuyinakekela. Ilungele imidiya evamile yokusebenza njengamanzi, izincibilikisi, ama-asidi, negesi yemvelo. Isetshenziselwa kakhulu ukusika noma ukuxhuma i-medium epayipini, futhi ingasetshenziselwa ukulawula nokulawula uketshezi.

Uma kuqhathaniswa nezinye izinhlobo zama-valve,ama-valve ebhola we-pneumaticube nenzuzo ye-torque encane ye-angular, ukuvulwa okusheshayo nokushelelayo, ukusebenza okuthembekile, nokusebenza okubanzi.

1. I-thrust bear inciphisa i-torque ye-valve stem, okwenza isiqu se-valve sisebenze kahle futhi siguquguquke isikhathi eside.

2. Umsebenzi we-Anti-static: Iziphethu zifakwa phakathi kwendilinga, isiqu se-valve, nomzimba we-valve, ongakhipha ugesi omile okhiqizwe phakathi nenqubo yokushintsha.

3. Ngenxa yezakhiwo ezinhle kakhulu zokuzigcoba zezinto ezifana ne-polytetrafluoroethylene, kukhona ukulahlekelwa okuncane kokungqubuzana phakathi kwebhola le-valve nomzimba we-valve. Ngakho-ke, impilo yesevisi yama-valve ebhola womoya yinde kakhulu.

4. Ukumelana noketshezi oluphansi: I-valve yebhola yomoya iwuhlobo lwe-valve enokumelana okuncane koketshezi phakathi kwazo zonke izigaba zamavalvu. Ngisho nevalvu yebhola yomoya encishisiwe enobubanzi inokumelana noketshezi oluncane.

5. Ukuvalwa kwesiqu se-valve okunokwethenjelwa: Njengoba isiqu se-valve sihamba kuphela ukunyakaza okujikelezayo futhi hhayi ukunyakaza kokuphakamisa okuqondile, uphawu lokupakisha lwesiqu se-valve mancane amathuba okuthi lonakale, futhi amandla alo okuvala ayanda njengoba ingcindezi ye-medium ikhula.

6. Ukusebenza kahle kokuvalwa kwesihlalo se-valve: Indandatho yokuvala yenziwe ngezinto ezinwebekayo njenge-polytetrafluoroethylene. Isakhiwo kulula ukuvala, futhi umthamo wokuvala we-valve yebhola yomoya uyakhula njengoba umfutho ophakathi ukhuphuka.
