Intshayelelo kwiivalvu zeBhola

Iivalvu zebhola

Ivalve yeBhola yivalve ejikelezayo ejikelezayo esebenzisa idisk emile okwebhola ukumisa okanye ukuqalisa ukuhamba. Ukuba ivalve ivuliwe, ibhola ijikeleza ukuya kwindawo apho umngxuma ophumela ebholeni ungqamene nevalve yomzimba wokungena kunye nokuphumayo. Ukuba ivalve ivaliwe, ibhola iyajikeleziswa ukuze umngxuma ube perpendicular ukuya kuvula umzimba wevalvu kwaye ukuhamba kuyekile.

Iintlobo zeevalvu zeBhola

Iivalvu zebhola zifumaneka kwiinguqulelo ezintathu: i-port epheleleyo, i-venturi port kunye ne-port encitshisiweyo. I-valve ye-port epheleleyo ine-diameter yangaphakathi elingana nobubanzi obungaphakathi bombhobho. I-Venturi kunye neenguqulelo ze-port ezincitshisiweyo ngokubanzi zincinci ubukhulu bombhobho omnye kunobukhulu bomgca.

Iivalvu zebhola zenziwe ngolungelelwaniso lomzimba olwahlukileyo kwaye ezona zixhaphakileyo zezi:

• Iivalvu zebhola zokungena eziphezulu zivumela ukufikelela kwivalvu yangaphakathi ukuze kugcinwe ngokukhutshwa kwevalve yeBhonethi-isigqubuthelo. Akudingeki ukuba kususwe i-valve kwinkqubo yombhobho.
• I-Slit body Ivalvu yebhola inamalungu amabini, apho elinye ilungu lincinci njengelinye. Ibhola ifakwe kwinxalenye enkulu yomzimba, kwaye inxalenye yomzimba omncinci ihlanganiswe ngoxhumo oluboshiweyo.

Iziphelo zevalve ziyafumaneka njenge-butt welding, i-socket welding, i-flanged, i-threaded kunye nabanye.

Izixhobo – Uyilo – Ibhonethi

Izinto eziphathekayo

Iibhola zihlala zenziwe ngeentsimbi ezininzi, ngelixa izihlalo zivela kwizinto ezithambileyo ezifana neTeflon®, iNeoprene, kunye nendibaniselwano yezi zixhobo. Ukusetyenziswa kwezixhobo zesihlalo esithambileyo kunika isakhono esihle sokutywina. Ukungalungi kwezixhobo ze-soft-seat (izinto ze-elastomeric) kukuba, azikho zingasetyenziswa kwiinkqubo zokushisa okuphezulu.

Umzekelo, izihlalo zepolymer ezinefluorinated zingasetyenziselwa ubushushu benkonzo ukusuka ku-−200° (nangaphezulu) ukuya kuma-230°C nangaphezulu, lo gama izihlalo zegraphite zinokusetyenziswa kumaqondo obushushu ukusuka ku-?° ukuya ku-500°C nangaphezulu.

Uyilo lwesiqu

Isiqu esikwivalve yeBhola asincanyathiselwanga ebholeni. Idla ngokuba nenxalenye yoxande ebholeni, kwaye loo nto ingena kwisithuba esisikwe ebholeni. Ukwandiswa kuvumela ukujikeleziswa kwebhola njengoko ivalve ivuliwe okanye ivaliwe.

Ibhonethi yevalve yebhola

Ibhonethi yevalve yeBhola ibotshelelwa emzimbeni, obambe i-stem assembly kunye nebhola endaweni. Ukulungelelaniswa kweBonnet kuvumela ukunyanzeliswa kokupakisha, okubonelela ngesitywina se-stem. Izinto zokupakisha izikhondo zevalve yeBhola idla ngokuba yiTeflon® okanye iTeflon-ezaliswe okanye iO-rings endaweni yokupakisha.

Iivalvu zebhola izicelo

Oku kulandelayo zezinye iinkqubo eziqhelekileyo zeevalvu zeBhola:

• Ukusetyenziswa komoya, igesi, kunye nolwelo
• Imijelo kunye neendawo zokuphuma kulwelo, igesi, kunye nezinye iinkonzo zolwelo
• Inkonzo yomphunga

Izinto eziluncedo kunye nezingeloncedo kwiivalvu zeBhola

Izinto eziluncedo:

• Umsebenzi wokucima ikota ngokukhawuleza
• Ukutywinwa okuqinileyo ngetorque ephantsi
• Incinci ngobungakanani kunezinye iivalvu ezininzi

Izinto ezingeloncedo:

• Iivalvu zeBhola eziqhelekileyo zineempawu ezilambathayo
• Kwi-slurry okanye ezinye izicelo, amasuntswana amisiweyo angazinza kwaye avaleleke kwimingxuma yomzimba ebangela ukuguga, ukuvuza, okanye ukusilela kwevalvu.
