Uthelekiso lokuSebenza lwe-DBB kunye ne-DIB trunnion Enyuswe ivelufa yebhola

Ibhola yevalve yebhola efakwe kwitrunnion igxininisiwe kwaye isitulo sevalve siyadada. Isihlalo sevalve sinokwahlulwa sibe yi-piston effect enye (SPE) okanye isenzo sokuzikhulula,

kunye nesiphumo sepiston kabini, (DPE.) Isitulo sevalve yepiston enye sinokutywinwa kwicala elinye. Isitulo sevalve yepiston ezimbini sinokufikelela ukutywinwa kumacala omabini.

Ukuba sisebenzisa i-→ │ isimboli yepiston ye-SPE kunye ne-→ │← isimboli ye-DPE, iintlobo ezine zeevalvu ezidweliswe ngasentla zinokuchongwa kusetyenziswa iMifanekiso 1-4

Isazobe soku-1 DBB (SPE-SPE)

Umzo.2 DIB (DPE+DPE)

Umfanekiso we-3 DIB-1 (SPE+DPE)

Fig4. DIB-2 (DPE+SPE)

KuMzobo 1, xa ulwelo luhamba ukusuka kwesobunxele ukuya ngasekunene, isihlalo sevalve ephezulu (SPE) sidlala indima yokutywina, kwaye phantsi kwefuthe loxinzelelo lwamanzi,

Isitulo sevalve ephezulu sibambelela ebholeni ukuphumeza ukutywinwa. Ngeli xesha, isitulo sevalve esezantsi asidlali indima yokutywina.

Xa isixa esikhulu segesi yoxinzelelo oluphezulu iveliswa kwigumbi levalvu kwaye uxinzelelo olwenziweyo lukhulu kunamandla entwasahlobo yesitulo sevalve esezantsi,

isihlalo sevalve esezantsi siya kuvuleka ukuze siphumeze ukuthomalalisa uxinzelelo. Ngokuchasene noko, isihlalo sevalve esezantsi sisebenza njengomsebenzi wokutywina,

ngelixa isihlalo sevalve ephezulu sisebenza njengomsebenzi wokunciphisa uxinzelelo. Yile nto siyibize ngebloko ephindwe kabini kunye nevalve yeBleed.

KuMzobo 2, xa ulwelo luhamba ukusuka kwesobunxele ukuya ngasekunene, isihlalo sevalve ephezulu (DEP) siya kudlala indima yokutywina,

ngelixa isihlalo sevalve esezantsi sinokudlala indima yokutywina. Kwimveliso yokwenyani yosetyenziso, isitulo sevalvu esezantsi sidlala indima yokhuseleko kabini.

Xa isitulo sevalve ephezulu sivuza, isitulo sevalvu esezantsi sisengahlala sitywiniwe. Ngokufanayo, xa ulwelo luhamba ukusuka ekhohlo ukuya ngasekunene,

isihlalo sevalve esezantsi sidlala indima enkulu yokutywina, ngelixa isitulo sevalvu enyukayo sidlala indima yokhuseleko ezimbini. Ukungalungi kukuba xa igesi ephezulu yoxinzelelo

Iveliswa kwigumbi levalvu, akukho zihlalo zevalvu ezinyukayo okanye ezisezantsi zingakwazi ukufikelela kuxinzelelo loxinzelelo, ezinokufuna ukusetyenziswa kwevalve yokhuseleko.

ixhunywe ngaphandle kwevalve, ukwenzela ukuba uxinzelelo olukhulayo kwi-cavity lukhutshwe ngaphandle, kodwa ngelo xesha, longeza indawo yokuvuza.

KuMzobo 3, xa ulwelo luhamba ukusuka ekhohlo ukuya ekunene, isitulo sevalvu enyukayo sinokudlala indima yokutywina, kwaye isihlalo sevalve esineendlela ezimbini esisezantsi sinakho.

dlala indima yokutywina kabini. Ngale ndlela, nokuba isihlalo sevalvu enyukayo sonakele, isihlalo sevalve esezantsi sisengahlala sitywiniwe. Xa uxinzelelo ngaphakathi

umgodi uphakama ngequbuliso, uxinzelelo lunokukhutshwa ngesitulo sevalve ephezulu, enokuthiwa inesiphumo sokutywinwa esifana nezihlalo ezimbini zevalve ye-DIB-1,

Nangona kunjalo, inokufezekisa ukukhululeka koxinzelelo oluzenzekelayo kwisiphelo sesihlalo sevalve ephezulu, ukudibanisa izibonelelo zazo zombini i-DBB kunye neevalvu ze-DIB-1.

KuMzobo 4, iphantse yafana naleyo yoMfanekiso 3. Umahluko kuphela kukuba xa uxinzelelo lwegumbi levalve lukhuphuka, isiphelo sesihlalo sevalve esisezantsi siyaqonda.

ukukhululeka koxinzelelo oluzenzekelayo. Ngokubanzi, ngokwembono yetekhnoloji, kunengqiqo kwaye kukhuselekile ukukhulula uxinzelelo olungaqhelekanga phakathi.

igumbi ukuya phezulu. Ngoko ke, idizayini yangaphambili iya kusetyenziswa, ngelixa i-design yamva ingenalo ixabiso elisebenzayo, elinqabileyo kakhulu kwizicelo eziphathekayo.

Kufuneka kugxininiswe ukuba ngokubanzi, isitulo sevalve ephezulu sidlala indima enkulu yokutywina kwaye sisetyenziswa rhoqo, okukhokelela kumonakalo omkhulu.

Ukuba isihlalo sevalve esezantsi sinokudlala indima yokutywina ngeli xesha, kukuqhubela phambili kobomi bevalve. Esi sisizathu sokuba kutheni i-DIB-1 kunye ne-DIB-2 (SPE+DEP)

iivalve zinobomi obude benkonzo xa kuthelekiswa nezinye iivalvu.
