Iivalvu zebholakwayeiivalvu zebhabhathane Ziindidi ezimbini ezibalulekileyo zeevalvu kwaye zisetyenziswa kakhulu. Ivalvu yebhola ifuna ukutywinwa okungqongqo kubushushu obuphezulu kunye noxinzelelo oluphezulu kunye nokumelana nokuhamba kwamanzi okuphantsi. Iivalvu zeButterfly zisetyenziselwa ikakhulu iimeko zokusebenza ezineemfuno zoxinzelelo oluphantsi kunye nokuvalwa okuphantsi.

 

Kukwakho neendlela ezininzi zokwahlulahlula iivalvu zebhola kunye neevalvu zebhabhathane. Iivalvu zebhola zingahlulwahlulwa zibe: iivalvu zentsimbi ezitywiniweyo ngokuqinileyo, iivalvu zebhola ezitywiniweyo ezithambileyo, iivalvu zebhola ezidadayo, iivalvu zebhola ezizinzileyo, iivalvu ze-semi-ball ezingaqhelekanga, iivalvu zebhola ezilawulayo ezimile okwe-V, njl.

 

Ivalvu yebhabhathane yahlulwe yaba: ivalvu yebhabhathane engaqhelekanga emithathu, ivalvu yebhabhathane engaqhelekanga kabini, ivalvu yebhabhathane esembindini, ivalvu yebhabhathane eqinileyo, ivalvu yebhabhathane ethambileyo.

 

Iivalvu zebhola kunye neevalvu zebhabhathane ziivalvu ezisetyenziswa rhoqo. Kwezinye iimeko, zombini zingasetyenziswa rhoqo, kwaye kwezinye iimeko zokusebenza, enye kuphela yazo ingasetyenziswa. Iimpawu zezi ntlobo zimbini zeevalvu. Sihlalutya ngokufutshane:

Ivalvu yebhola: ivalvu yeqhude yavela, inxalenye yokuvula neyokuvala yisphere, iimpawu zezi:

1. Ukumelana nokujikeleza kwegazi kuncinci. Xa ivuliwe ngokupheleleyo, akukho zinxalenye zithintela ukuhamba kwesixhobo esikwitshaneli;

2. Ingatywinwa ngokupheleleyo phantsi koxinzelelo oluphezulu kunye nobushushu obuphezulu;

3. Ingavulwa ize ivalwe ngokukhawuleza;

4. Ukwazi ukumelana nokuguguleka okuphezulu kunye nokumelana nokugqwala okunamandla ngonyango lokuqina;

5. Umzimba wevalvu ulingana, onokumelana ngempumelelo noxinzelelo lombhobho kwaye unokumelana neemeko zokusebenza ezinoxinzelelo oluphezulu.

 

Ivalvu yebhabhathane: Inxalenye yokuvula neyokuvala yipleyiti yebhabhathane yohlobo lwediski, ephawulwa ngolu hlobo lulandelayo:

1. Isakhiwo esilula, ubungakanani obuncinci kunye nofakelo olulula;

2. I-coefficient encinci yokumelana nokuhamba kwamanzi, ukuvulwa nokuvalwa ngokukhawuleza;

3. Ingasetyenziselwa iivalvu ezinkulu ezinobubanzi;

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

 

Xa kuthelekiswa nevalvu yebhola, ivalvu yebhabhathane inomsebenzi ombi wokutywina, kodwa phakathi kweevalvu ezinkulu, ivalvu yebhabhathane inenzuzo ekhethekileyo kunevalvu yebhola; xa isetyenziselwa ukulungisa isantya sokuhamba, ivalvu yebhabhathane inoluhlu oluncinci lohlengahlengiso, ngelixa ivalvu yebhola yohlengahlengiso yohlobo lwe-V ihlengahlengiswa. Kwimibhobho enoxinzelelo oluphezulu, iivalvu zebhola zinezibonelelo kuneevalvu zebhabhathane.
