Iivalvu zebholakwayeiivalve butterfly ziindidi ezimbini ezibalulekileyo zeevalvu kwaye zisetyenziswa ngokubanzi.I-valve yebhola idinga ukutywinwa okungqongqo kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu kunye nokumelana nokuhamba okuphantsi.Iivalve zebhabhathane zisetyenziswa ikakhulu kwiimeko zokusebenza ezinoxinzelelo oluphantsi kunye neemfuno zokutywinwa okuphantsi.

 

Kukwakho iindidi ezininzi zeevalvu zebhola kunye neevalve zebhabhathane.Iivalve zebhola zinokwahlulwa zibe: iivalve zebhola ezitywiniweyo eziqinileyo, iivalve zebhola ezitywiniweyo ezithambileyo, iivalve zebhola ezidadayo, ivalve yebhola esisigxina, i-eccentric semi-ball valves, iivalve zebhola ezimilise u-V, njl.

 

Ivalve yebhabhathane yahlulwe yaba: ivelufa yebhabhathane eccentric, ivalve yebhabhathane eccentric ephindwe kabini, ivalve yebhabhathane esembindini, ivelufa yebhabhathane etywina eqinileyo, ivalve yebhabhathane etywiniweyo ethambileyo.

 

Iivalve zebhola kunye neevalve zebhabhathane zidla ngokusetyenziswa.Kwezinye iimeko, zombini zingasetyenziselwa ukusetyenziswa okuqhelekileyo, kwaye kwezinye iimeko zokusebenza, enye kuphela ingasetyenziswa.Iimpawu ezichaphazelekayo zezi ntlobo zimbini zeevalvu.Sihlalutya ngokufutshane:

Ivalve yebhola: ivalve yeqhude yavela, indawo yokuvula kunye nokuvala yingqukuva, iimpawu zezi:

1. Ukumelana nokujikeleza kuncinci.Xa ivulwe ngokupheleleyo, akukho malungu athintela ukuhamba komthombo kumjelo;

2. Inokuvalwa ngokupheleleyo phantsi koxinzelelo oluphezulu kunye nokushisa okuphezulu;

3. Inokuvulwa kwaye ivalwe ngokukhawuleza;

4. Ukuqonda ukunganyangeki okuphezulu kunye nokuxhathisa okuqinileyo kwe-corrosion ngonyango olunzima;

5. Umzimba wevalve u-symmetrical, onokunyamezela ngokufanelekileyo uxinzelelo lwepayipi kwaye unokumelana neemeko zokusebenza zoxinzelelo oluphezulu.

 

Ivalve yebhabhathane: Indawo yokuvula neyokuvala yipleyiti yebhabhathane yodidi lwediski, ephawulwa ngoku:

1. Isakhiwo esilula, ubungakanani obuncinci kunye nofakelo olufanelekileyo;

2. I-coefficient yokumelana nokuhamba okuncinci, ukuvula ngokukhawuleza kunye nokuvala;

3. Ingasetyenziselwa iivalvu ezinkulu zedayamitha;

4. Iindawo ezahlukeneyo zokutywina zingasetyenziswa kwiindawo ezahlukeneyo, kubandakanywa i-powdery kunye ne-granular media.

 

Xa kuthelekiswa nevalve yebhola, ivalve yebhabhathane inomsebenzi wokutywina ombi kancinci, kodwa phakathi kweevalve ezinobubanzi obukhulu, ivalve yebhabhathane inenzuzo eyodwa ngaphezulu kwevalve yebhola;xa isetyenziselwa ukulungelelanisa izinga lokuhamba, i-valve ye-butterfly inoluhlu oluncinci lohlengahlengiso, ngelixa i-valve yebhola ye-V-hlobo iyalungiswa.Kwimibhobho yoxinzelelo oluphezulu, iivalvu zebhola zineenzuzo ngaphezu kweevalve zebhabhathane.
