Ivalve yebholakunye nevalve yeplagi luhlobo olufanayo lwevalve, indawo yayo yokuvala kuphela yibhola, ibhola ijikeleza umgca osembindini womzimba wevalvu ukufikelela evulekileyo, ivalwe ivalve.Ivalve yebhola kumbhobho isetyenziswa ikakhulu ukusika, ukusasazwa kunye nokutshintsha indlela yokuhamba kwendawo.Ivalve yebhola isetyenziswa kakhulu kwiminyaka yakutshanje luhlobo olutsha lwevalve yebhola yevalve kunye nevalve yeplagi luhlobo olufanayo lwevalve, indawo yayo yokuvala kuphela yibhola, ibhola ejikeleze umgca osembindini womzimba wevalve ukuze uvule kwaye uvale. ivalve.

Ivalve yebholakumbhobho ikakhulu isetyenziselwa ukunqumla, ukusasazwa kunye nokutshintsha indlela yokuhamba kwendlela.Ivalve yebhola luhlobo olutsha lwevalve esetyenziswe ngokubanzi kwiminyaka yakutshanje.Inoncedo olulandelayo:

1. Ukuxhatshazwa kwamanzi kuncinci, kwaye i-coefficient yayo yokumelana ilingana necandelo lombhobho lobude obufanayo.

2. Isakhiwo esilula, umthamo omncinci, ubunzima obulula.

3. Iqinile kwaye inokwethenjelwa, indawo yokutywina yomgangatho wevalve yebhola isetyenziswa ngokubanzi iplastiki, ukutywinwa kakuhle, kwaye isetyenziswe ngokubanzi kwinkqubo yokucoca.

4. Kulula ukusebenza, vula kwaye uvale ngokukhawuleza, ukusuka ekuvuleni ngokupheleleyo ukuya kukuvalwa ngokupheleleyo nje ngokujikeleza kwe-90 °, ekulungele ukulawula kude.

5. Ukugcinwa okulula, isakhiwo sevalve yebhola silula, ikhonkco lokutywina lisebenza ngokubanzi, ukuchithwa kunye nokutshintshwa kulungeleka ngakumbi.

6. Xa ivuliwe ngokupheleleyo okanye ivalwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo sevalvu yodwa kuphakathi.Xa i-medium idlula, ayiyi kubangela ukhukuliseko lomphezulu wokutywina wevalve.

7. Isebenza kuluhlu olubanzi lweesayizi ukusuka kwincinci ukuya kwiimilimitha ezimbalwa ukuya kwiimitha ezimbalwa, ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu lunokusetyenziswa.

Ivalve yebholaisetyenziswe kakhulu kwi-petroleum, kwishishini lemichiza, ekuveliseni amandla, ekwenzeni iphepha, amandla e-athom, inqwelomoya, iirokethi kunye namanye amasebe, kunye ne-People's Daily Life.
