Kugereranya Imikorere ya DBB na DIB trunnion Yashizwe kumupira wumupira

Umupira wa trunnion ushyizwemo bal valve irashizweho kandi intebe ya valve ireremba. Intebe ya valve irashobora kugabanywa mubikorwa bya piston imwe (SPE) cyangwa ibikorwa byo kwikuramo,

n'ingaruka ebyiri za piston, (DPE.) Intebe imwe ya piston ya valve irashobora gufungwa gusa icyerekezo kimwe. Intebe ya piston ebyiri irashobora kugera kashe mubyerekezo byombi.

Niba dukoresheje ikimenyetso → │ kuri piston ya SPE hamwe na → │ ← ikimenyetso cya DPE, ubwoko bune bwimibiri yavuzwe haruguru burashobora kumenyekana ukoresheje Ishusho 1-4

Igishushanyo 1 DBB (SPE-SPE)

Igishushanyo.2 DIB (DPE + DPE)

Igishushanyo.3 DIB-1 (SPE + DPE)

Igishushanyo4. DIB-2 (DPE + SPE)

Mu gishushanyo cya 1, iyo amazi atemba ava ibumoso ugana iburyo, intebe yo hejuru ya valve (SPE) igira uruhare mukidodo, kandi bitewe numuvuduko wamazi,

intebe yo hejuru ya valve yifatira kumupira kugirango igere kashe. Muri iki gihe, icyicaro cyo hasi cya valve ntikigiramo uruhare.

Iyo umubare munini wa gaze yumuvuduko mwinshi ubyara mucyumba cya valve kandi umuvuduko ukomoka uruta imbaraga zamasoko yintebe yimbere ya valve,

intebe yo hepfo ya valve izakingurwa kugirango igabanye umuvuduko. Ibinyuranyo, intebe yo hepfo ya valve ikora nkigikorwa cyo gufunga,

mugihe intebe yo hejuru ya valve ikora nkigikorwa cyo gutabara birenze urugero. Ibi nibyo twise double block na Bleed valve.

Igishushanyo cya 2, mugihe amazi atemba ava ibumoso ugana iburyo, intebe yo hejuru ya valve (DEP) izagira uruhare mukidodo,

mugihe intebe yimbere ya valve nayo ishobora kugira uruhare rwo gufunga. Mubikorwa nyabyo byokubyara umusaruro, intebe yimbere ya valve mubyukuri ifite uruhare runini rwumutekano.

Iyo intebe yo hejuru ya valve isohotse, intebe yimbere ya valve irashobora kuguma ifunze. Mu buryo nk'ubwo, iyo amazi atemba ava ibumoso ugana iburyo,

intebe yo hasi ya valve ifite uruhare runini rwo gufunga, mugihe intebe yo hejuru ya valve ifite uruhare runini rwumutekano. Ikibi nuko iyo gaze yumuvuduko mwinshi

ikorerwa mubyumba bya valve, ntamwanya wo hejuru cyangwa epfo na ruguru intebe irashobora kugera kubutabazi bwumuvuduko, bishobora gusaba gukoresha ikoreshwa ryubutabazi bwumutekano

ihujwe n’inyuma ya valve, kugirango umuvuduko uzamuka mu cyuho ushobora kurekurwa hanze, ariko icyarimwe, wongeyeho ingingo yamenetse.

Mu gishushanyo cya 3, iyo amazi atemba kuva ibumoso ugana iburyo, intebe yo hejuru ya valve irashobora kugira uruhare mukidodo, kandi intebe yo hepfo yinzira ebyiri-intebe irashobora kandi

Gira uruhare runini. Ubu buryo, nubwo intebe yo hejuru ya valve yangiritse, intebe yo hasi ya valve irashobora gukomeza gufungwa. Iyo igitutu imbere

umwobo uzamuka gitunguranye, igitutu kirashobora kurekurwa hifashishijwe intebe yo hejuru ya valve, bishobora kuvugwa ko bifite ingaruka zisa nkizifunga nkuko imyanya ibiri yinzira ebyiri zibiri DIB-1,

Ariko, irashobora kugera kubutabazi bwihuse kurwego rwo hejuru rwicyicaro cyimbere, ihuza ibyiza byombi DBB na DIB-1.

Mu gishushanyo cya 4, birasa nkibiri mu gishushanyo cya 3. Itandukaniro gusa ni uko iyo umuvuduko uri mu cyumba cya valve uzamutse, intebe yimbere ya valve irangira ibimenya

kugabanuka k'umuvuduko ukabije. Muri rusange, ukurikije tekinoroji, birumvikana kandi bifite umutekano kurekura umuvuduko udasanzwe hagati

icyumba kugeza hejuru. Kubwibyo, ibishushanyo mbonera bizakoreshwa, mugihe igishushanyo cya nyuma nta gaciro gifite, kikaba ari gake cyane mubikorwa bifatika.

Twakagombye gushimangira ko muri rusange, intebe yo hejuru ya valve igira uruhare runini rwo gufunga kandi ikoreshwa kenshi, bikavamo amahirwe menshi yo kwangirika.

Niba intebe yo hepfo yimbere ishobora no kugira uruhare mukidodo muriki gihe, ni ugukomeza ubuzima bwa valve. Ninimpamvu yatumye DIB-1 na DIB-2 (SPE + DEP)

indangagaciro zifite ubuzima burebure bwa serivisi ugereranije nizindi valve.
