Iivalvu zeglowubhu zeBellows, ezikwabizwa ngokuba ziivalvu zeglowubhu ezitywiniweyo, ziyilelwe ukudala umqobo wesinyithi phakathi kwendawo yolwelo kunye neatmosfera nge-automatic hob-welding ukuqinisekisa ukuvuza kwesiqu esingu-zero. Xa kuthelekiswa nevalve yeglowubhu yemveli inezi nzuzo zilandelayo:
1. I-Bellows globe valve ubomi benkonzo ende, ukunciphisa inani lokugcinwa, ukunciphisa iindleko zokusebenza. Uyilo lwetywina lwemibhobhobhozo luqinisekisa ukuvuza kwesiqu esingu-zero kwaye lubonelela ngeemeko ezingenalulondolozo.
2. I-Valve yokuvula kunye ne-torque yokuvala incinci, inciphisa amandla okusebenza, kwaye inokuqhuba naluphi na uhlobo lwesixhobo sokuqhuba, kulula ukulawula kude.
3. Inkangeleko entle, ishaneli yevalve inomgca wokuhamba kakuhle, ukunciphisa i-coefficient yokumelana nokuhamba kwevalve, luhlobo lwemveliso ephezulu yokugcina amandla.
4. Isitywina sangaphandle sevalve sisebenzisa i-bellows seal kunye negraphite, insimbi engenasici ye-gasket seal, isitywina esithembekileyo, ukusetyenziswa kwexesha elide akukwazi ukuthatha indawo yokupakisha ukutywinwa. Kusetyenziso lwemizi-mveliso, ivalve yokuyeka eqhelekileyo ebangelwa kukuvuza: ubushushu obuphezulu, ityhefu ephezulu, inokutsha kunye nokuqhushumba, imithombo yeendaba ene-radioactive njalo njalo, kungekuphela nje ukungcoliseka kwendalo, kodwa ikwabangela ilahleko enkulu yomntu kunye nepropathi. Ivalve yokumisa i-bellows ikhuseleke ngakumbi kwaye izinzile, kwaye imigangatho ephezulu yehlabathi yamkelwa ngokungqongqo kuyilo kunye nokuveliswa.
Izinto eziluncedo kunye nokusetyenziswa kwevalve yeglowubhu
Ivalve yokumisa iBellows ayivuzi, isetyenziswa kumajelo eendaba asemngciphekweni omkhulu ikhuselekile.
Iivalvu zeglowubhu eziqhelekileyo zitywinwe ngokupakishwa, phakathi kwesiqu kunye nokupakishwa kuya kutyibilika, kulula ukuvuza kwiqondo lobushushu eliphantsi (spool).
Ivalve yeglowubhu yeBellows inokolulwa kwaye icinezelwe intsimbi yokutywina endaweni yokupakisha itywina, inokuthintela ngempumelelo ilahleko yokupakisha ebangelwa kukuvuza kwangaphandle. Ngokuqhelekileyo isetyenziselwa ukusasaza okuphakathi okunamandla okuvuzayo, okufana nevalve kwinkqubo ye-hydrogen, okoko nje imivumbo ingonakaliswanga, akukho kuvuza ngokubanzi; Kwaye ivalve yeglowubhu ngokubanzi ngokupakishwa ukutywinwa, kulula ukuvuza.
Olu hlobo lwe-valve stem yokuvula okanye i-stroke yokuvala ifutshane, kwaye inomsebenzi othembekileyo wokusika, kwaye ngenxa yokutshintshwa kwesihlalo sevalve ngokusebenzisa i-stroke ye-disc ihambelana ngokuthe ngqo nobudlelwane, ilungele kakhulu ukulawulwa kokuhamba. Ngoko ke, olu hlobo lwevalve lufanelekile ukusika okanye ukulawula kunye nokusetyenziswa kwe-throttling.
