Iimpawu zeevalvu zebhola.

1. Ukunganxibi 

Kuba umbindi wevalve yevalve yebhola etywiniweyo yintsimbi yentsimbi etshizwe ngewelding kwaye umsesane wokutywina yintsimbi yealloyi eyalekayo,ivalve yebhola etywiniweyoayiyi kubangela ukugqoka ngokugqithiseleyo ngexesha lokuvula nokuvala. (I-coefficient yokuqina kwayo yi-65-70):

2. Ukusebenza kokutywina okugqwesileyo

Ekubeni ukutywinwa kwevalve yebhola evaliweyo kufezekiswa ngokusila ngesandla, kwaye inokusetyenziswa kuphela xa i-valve core kunye nendandatho yokutywina ihambelana ngokugqibeleleyo, ukutywinwa kwayo kuthembekile.

3. Ukusebenza okungenamagingxigingxi

Ngenxa yokuba i-bottom of the ring of sealing of the hard-sealed ball valve ixhotyiswe nge-spring eqinisekisa ngokungqongqo umsesane wokutywina kunye ne-valve core kunye, i-valve inokuvulwa kwaye ivalwe ngokulula kakhulu xa amandla angaphandle edlula amandla okuqinisa kwangaphambili entwasahlobo.

4. Ubomi benkonzo ende

Isetyenziswe ngokubanzi kwiinkalo ezahlukeneyo ezifana ne-petroleum, ishishini lemichiza, ukuveliswa kwamandla, ukwenza iphepha, amandla e-athom, ukuhamba ngeenqwelomoya, iirokethi, njl., kunye nakubomi bemihla ngemihla babantu.

I-valve yebhola ye-pneumatic inesakhiwo esidibeneyo, ukutywinwa okuthembekileyo, ukuyila okulula, kunye nokugcinwa okufanelekileyo. Umphezulu wokutywina kunye nomphezulu we-spherical uhlala kwindawo evaliweyo, engenakwenzeka ukuba ikhutshwe yi-medium kwaye kulula ukuyisebenzisa nokugcina. Ifanelekile kumajelo asebenza ngokubanzi njengamanzi, izinyibilikisi, iiasidi, kunye negesi yendalo. Isetyenziselwa ikakhulu ukunqumla okanye ukudibanisa okuphakathi kumbhobho, kwaye ingasetyenziselwa ukulawula nokulawula ulwelo.

Xa kuthelekiswa nezinye iintlobo zeevalvu,iivalve zebhola yepneumaticYiba nenzuzo yetorque encinci ye-angular, ukuvulwa okukhawulezayo kunye nokugudileyo, ukusebenza okuthembekileyo, kunye nokusebenza okubanzi.

1. I-thrust bearing inciphisa i-torque ekhukhulayo yesikhondo sevalve, ivumela isiqu sevalve sisebenze kakuhle kwaye sibhetyebhetye ixesha elide.

2. Umsebenzi we-Anti-static: Imithombo ifakwe phakathi kwe-sphere, i-valve stem, kunye nomzimba we-valve, onokukhupha umbane osisigxina owenziwe ngexesha lenkqubo yokutshintsha.

3. Ngenxa yeempawu ezibalaseleyo zokuzithambisa zemathiriyeli ezifana ne-polytetrafluoroethylene, kukho ilahleko encinci yokukhuhlana phakathi kwebhola yevalve kunye nomzimba wevalvu. Ke ngoko, ubomi benkonzo yeevalvu zebhola zepneumatic bude kakhulu.

4. Ukumelana nolwelo oluphantsi: Ivalve yebhola ye-pneumatic luhlobo lwevalve enobuncinci bokuxhathisa ulwelo phakathi kwazo zonke izigaba zevalvu. Nkqu nevalve yebhola yepneumatic encitshisiweyo inomlinganiselo omncinci wokuxhathisa ulwelo.

5. Ukutywinwa kwe-valve stem ethembekileyo: Ekubeni i-valve stem ihamba kuphela intshukumo ejikelezayo kwaye ayiphakamisi intshukumo ethe nkqo, isitywina sokupakisha se-valve stem ayinakwenzeka ukuba sonakaliswe, kwaye umthamo wayo wokutywina uyanda njengoko uxinzelelo oluphakathi lukhula.

6. Ukusebenza okugqwesileyo kokutywinwa kwesitulo sevalve: Iringi yokutywina yenziwe ngezinto ezilastiki ezifana ne-polytetrafluoroethylene. Ulwakhiwo kulula ukutywinwa, kwaye umthamo wokutywina wevalve yebhola ye-pneumatic uyanda njengoko uxinzelelo oluphakathi lukhuphuka.
