Ivalve yebhola yeplastiki yombane ingavalwa ngokuqinileyo kuphela nge-90 degree rotation kunye ne-torque encinci yokujikeleza. Umgodi wangaphakathi olinganayo ngokupheleleyo womzimba wevalvu ubonelela ukuchasana okuncinci kunye nokuhamba okuthe tye kumbindi.
Ngokuqhelekileyo kuqwalaselwa ukuba i-valve yebhola yeyona nto ifanelekileyo ekuvuleni ngokuthe ngqo kunye nokuvala, kodwa uphuhliso lwakutsha nje luye lwayila i-valve yebhola ukuze i-throttling kunye nokulawula ukuhamba. Olona phawu luphambili lwevalve yebhola lubume bayo obubambeneyo, ukusebenza ngokulula kunye nokugcinwa, ilungele amanzi, i-solvent, i-asidi kunye negesi yendalo kunye neminye imithombo yeendaba esebenza ngokubanzi, kodwa ifanelekile kwiimeko zokusebenza ezingezizo ezosasazo, njengeoksijini, ihydrogen peroxide, methane. kunye ne-ethylene. Umzimba wevalve yevalve yebhola unokudityaniswa okanye udityaniswe.
Ivalve yebhola sele isetyenziswa kakhulu kwipetroleum, imichiza, igesi enyibilikisiweyo, unikezelo lwamanzi kunye ne drainage, ukutya, amayeza, ukuvelisa umbane, ukwenza iphepha, ukwakhiwa kwedolophu, izimbiwa, inkqubo yebhoyila umphunga, umasipala, amandla athom, inqwelomoya, rocket kunye namanye amasebe, njengoko kunye nobomi bemihla ngemihla babantu.
Ivalve yebhola yeplastiki yombane ivele kwivalve yeplagi. Inomjikelezo ofanayo we-90 degrees yokuphakamisa isenzo, umahluko kukuba umzimba weqhude yibhola, kunye nesetyhula ngomngxuma okanye umjelo nge-axis yayo. Umlinganiselo womphezulu ongqukuva kwizibuko lomjelo kufuneka ube ngathi xa ibhola ijikeleza iidigri ezingama-90, i-inlet kunye ne-outlet kufuneka zonke zibengqukuva, ukuze kunqunyulwe ukuhamba.
Ivalve yebhola yeplastiki yombane ingavalwa ngokuqinileyo kuphela nge-90 degree rotation kunye ne-torque encinci yokujikeleza. Umgodi wangaphakathi olinganayo ngokupheleleyo womzimba wevalvu ubonelela ukuchasana okuncinci kunye nokuhamba okuthe tye kumbindi.
Ngokuqhelekileyo kuqwalaselwa ukuba i-valve yebhola yeyona nto ifanelekileyo ekuvuleni ngokuthe ngqo kunye nokuvala, kodwa uphuhliso lwakutsha nje luye lwayila i-valve yebhola ukuze i-throttling kunye nokulawula ukuhamba. Olona phawu luphambili lwevalve yebhola lubume bayo obubambeneyo, ukusebenza lula kunye nokugcinwa lula, ilungele amanzi, i-solvent, i-asidi kunye negesi yendalo kunye neminye imithombo yeendaba esebenza ngokubanzi, kodwa ifanelekile kwiimeko zokusebenza ezingezizo ezosasazo, njengeoksijini, ihydrogen peroxide, methane. kunye ne-ethylene.
Umzimba wevalve yevalve yebhola unokudityaniswa okanye udityaniswe. Umgaqo osebenzayo kunye nendima ebonakalayo yevalve yebhola yeplastiki yombane umgaqo osebenzayo wevalve yebhola kukwenza ivalve ingavalwanga okanye ivalwe ngokujikeleza ivalve.
Ivalve yebhola yokutshintsha ukukhanya, ubungakanani obuncinci, ingenziwa ibe yi-diameter enkulu, ukutywinwa okuthembekileyo, isakhiwo esilula, ukugcinwa okufanelekileyo, umphezulu wokutywina kunye nomphezulu we-spherical uhlala uvaliwe, akukho lula ukukhukuliseka okuphakathi, isetyenziswa ngokubanzi kumashishini ahlukeneyo. .
Ivalve yebhola yeplastiki yombane kunye nevalve yeplagi zezohlobo olufanayo lwevalve, indawo yayo yokuvala kuphela iyibhola, kwaye ibhola ijikeleza kumgca osembindini womzimba wevalvu ukuvula nokuvala ivalve. Ivalve yebhola isetyenziswa ikakhulu ukusika, ukusasaza kunye nokutshintsha indlela yokuhamba kombhobho ophakathi. Ivalve yebhola yeplastiki yombane luhlobo olutsha lwevalvu esetyenziswa kakhulu kwiminyaka yakutshanje.
Inezi ncedo zilandelayo:
1. Ukuchasana kwamanzi amancinci, i-coefficient yayo yokumelana ilingana nobude obufanayo becandelo lombhobho.
2. Isakhiwo esilula, umthamo omncinci kunye nobunzima obulula.
3. Iqinile kwaye ithembekile. Okwangoku, izinto zokutywina zomgangatho wevalve yebhola zenziwe ngokubanzi ngeplastiki kunye nokusebenza kakuhle kokutywinwa, kwaye isetyenziswe ngokubanzi kwinkqubo yokucoca.
4. Ukusebenza ngokufanelekileyo, ukuvulwa ngokukhawuleza kunye nokuvala, ukusuka ekuvuleni ngokupheleleyo ukuya ekuvaleni ngokupheleleyo nje ngo-90 ° ukujikeleza, kulungele ukulawula kude.
5. Ukugcinwa okulula, isakhiwo esilula se-valve yebhola, ikhonkco lokutywina elihambayo, ukuchithwa okulula kunye nokutshintshwa.
6. Xa ivalve ivulwe ngokupheleleyo okanye ivaliwe, indawo yokutywina yebhola kunye nesihlalo sevalve ibekwe yodwa ukusuka kwindawo ephakathi, kwaye i-medium ayiyi kubangela ukhukuliseko lomphezulu wokutywina wevalve.
7. Uluhlu olubanzi lwesicelo, ububanzi ukusuka kwincinci ukuya kwiimilimitha ezininzi, ukuya kwiimitha ezininzi, ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu lunokusetyenziswa.
Ivalve yebhola isetyenziswa ikakhulu ukudibanisa okanye ukuvala umbhobho ophakathi, ngakumbi kwiindawo ezifuna ukuvulwa nokuvala ngokukhawuleza, njengokothula ngokukhawuleza. Ngenxa yesakhiwo sayo esilula, iinxalenye ezincinci, ubunzima obulula kunye nokusebenza kakuhle kokutywinwa, isetyenziswa ngokubanzi
