Ivalvu yebhola yeplastiki yombane ingavalwa ngokuqinileyo kuphela ngokujikeleza okungama-90 degrees kunye ne-torque encinci yokujikeleza. Umngxuma wangaphakathi olinganayo ngokupheleleyo womzimba wevalvu unika ukumelana okuncinci kunye nendlela ethe tye yesixhobo.
Ngokuqhelekileyo kucingelwa ukuba ivalvu yebhola yeyona ifanelekileyo ekuvuleni nasekuvaleni ngqo, kodwa uphuhliso lwakutshanje luye lwayila ivalvu yebhola yokulawula ukugoba kunye nokuhamba kwamanzi. Uphawu oluphambili lwevalvu yebhola lulwakhiwo lwayo oluncinci, kulula ukuyisebenzisa kunye nokugcinwa kwayo, ifanelekile emanzini, isinyibilikisi, i-asidi kunye negesi yendalo kunye nezinye izixhobo zokusebenza ngokubanzi, kodwa ikwafanelekile nakwiimeko zokusebenza ezimbi zezixhobo, ezifana neoksijini, i-hydrogen peroxide, i-methane kunye ne-ethylene. Umzimba wevalvu yevalvu yebhola unokuba yi-integral okanye udityaniswe.
Ivalvu yebhola isetyenziswa kakhulu kwi-petroleum, iikhemikhali, igesi enyibilikisiweyo, ukuhanjiswa kwamanzi kunye nokutsalwa kwamanzi, ukutya, amayeza, ukuveliswa kwamandla, ukwenziwa kwamaphepha, ukwakhiwa kwedolophu, izimbiwa, inkqubo yomphunga webhoyila, umasipala, amandla e-athomu, uhambo ngeenqwelo-moya, irokhethi kunye namanye amasebe, kunye nobomi bemihla ngemihla babantu.
Ivalvu yebhola yeplastiki yombane iphuhliswe kwivalvu yeplagi. Inentshukumo efanayo yokuphakamisa ukujikeleza ngama-90 degrees, umahluko kukuba umzimba we-cock yibhola, enomngxuma ojikelezayo okanye umjelo odlula kwi-axis yayo. Umlinganiselo womphezulu ojikelezayo kwi-channel port kufuneka ube ngowokuba xa ibhola ijikeleza ngama-90 degrees, i-inlet kunye ne-outlet zonke kufuneka zibe yi-spherical, ukuze kunqunyulwe ukuhamba kwamanzi.
Ivalvu yebhola yeplastiki yombane ingavalwa ngokuqinileyo kuphela ngokujikeleza okungama-90 degrees kunye ne-torque encinci yokujikeleza. Umngxuma wangaphakathi olinganayo ngokupheleleyo womzimba wevalvu unika ukumelana okuncinci kunye nendlela ethe tye yesixhobo.
Ngokuqhelekileyo kucingelwa ukuba ivalvu yebhola yeyona ifanelekileyo ekuvuleni nasekuvaleni ngqo, kodwa uphuhliso lwakutshanje luye lwayila ivalvu yebhola yokulawula ukugoba kunye nokuhamba kwamanzi.

Umzimba wevalvu yevalvu yebhola unokuba yinto edibeneyo okanye edibeneyo. Umgaqo wokusebenza kunye nendima esebenzayo yevalvu yebhola yeplastiki yombane, umgaqo wokusebenza wevalvu yebhola kukwenza ivalvu ivuleke okanye ivalwe ngokujikelezisa ivalvu.
Isibane se-ball valve switch, esincinci ngobukhulu, singenziwa sibe nobubanzi obukhulu, ukutywinwa okuthembekileyo, isakhiwo esilula, ukugcinwa okulula, umphezulu wokutywinwa kunye nomphezulu ojikelezayo zihlala zivaliwe, akukho lula ukukhukuliseka yi-medium, isetyenziswa kakhulu kumashishini ahlukeneyo.
Ivalvu yebhola yeplastiki yombane kunye nevalvu yeplagi zezohlobo olufanayo lwevalvu, yinxalenye yayo yokuvala kuphela yibhola, kwaye ibhola ijikeleza umgca osembindini womzimba wevalvu ukuvula nokuvala ivalvu. Ivalvu yebhola isetyenziselwa kakhulu ukusika, ukusasaza nokutshintsha indlela yokuhamba kwesixhobo esiphakathi kwipayipi. Ivalvu yebhola yeplastiki yombane luhlobo olutsha lwevalvu olusetyenziswa kakhulu kwiminyaka yakutshanje.
Inezibonelelo ezilandelayo:
1. Ukumelana nolwelo oluncinci, i-coefficient yayo yokumelana ilingana nobude obufanayo becandelo lombhobho.
2. Ulwakhiwo olulula, umthamo omncinci kunye nobunzima obulula.
3. Iqinile kwaye ithembekile. Okwangoku, izinto zokutywina zevalvu yebhola zenziwe ngeplastiki kwaye zisebenza kakuhle ekutywineni, kwaye zisetyenziswa kakhulu kwinkqubo yokutywina.
4. Ukusebenza okulula, ukuvulwa nokuvalwa ngokukhawuleza, ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvaleni ngokupheleleyo ixesha elide ukuya kujikelezo lwe-90 °, olulungele ulawulo olukude.
5. Ukugcinwa lula, ulwakhiwo olulula lwevalvu yebhola, iringi yokutywina eshukumayo, ukuqhaqha nokutshintsha lula.
6. Xa ivalvu ivuliwe okanye ivaliwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo sevalvu uyahlukaniswa kwi-medium, kwaye i-medium ayizukubangela ukuwohloka komphezulu wokutywina ivalvu.
7. Uluhlu olubanzi lokusetyenziswa, ububanzi ukusuka kwi-millimeters ezincinci ukuya kwiimilimitha ezininzi, ukuya kwiimitha ezininzi, ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu lunokusetyenziswa.
Ivalvu yebhola isetyenziswa kakhulu ukudibanisa okanye ukuvala i-pipeline medium, ingakumbi kwiindawo ezifuna ukuvulwa nokuvalwa ngokukhawuleza, njengokukhutshwa kwempahla ngokukhawuleza. Ngenxa yesakhiwo sayo esilula, iindawo ezimbalwa, ubunzima obuphantsi kunye nokusebenza kakuhle kokuvala, isetyenziswa kakhulu.
