Uhlalutyo lomgaqo wokusebenza wevalve yokuhambisa

Ivalve ye-Isovolumetric: ngokubanzi inomphathi okhululayo ukunciphisa uxinzelelo.

Ivalve ye-Isobaric: inevalve yokubuyisela i-oyile, enokuthi icinezele ngokufanelekileyo inaliti yesibini kunye ne-cavitation emva kwesitofu.

(1) Ivalve yokuhambisa kunye nesihlalo sevalve zizinto ezichanekileyo ezihambelanayo, ezenziwe ngentsimbi yealloy ephezulu. Umngxuma wesikhokelo, ubuso obuphezulu kunye nezantsi ekupheleni kunye nomngxuma wesihlalo zicutshungulwa ngokuchanekileyo kwaye ziphantsi, kwaye azikwazi ukutshintshwa emva kokuhambelana.

(2) Inxalenye ye-conical yevalve yokuhambisa yi-axial cone yokutywinwa komphezulu wevalve. Inxalenye ye-conical yevalve iyatyibilika kumngxuma wesikhokelo ukukhokela. Umsila wenziwa ngomatshini ukuze wenze i-cross-shaped cross-section ukuvumela amafutha ukuba adlule. I-cylindrical surface embindini wevalve yokuhambisa ibizwa ngokuba yindawo yokunciphisa uxinzelelo, eyenza umthamo wokunciphisa uxinzelelo phakathi kwayo kunye ne-cone yokutywina.

(3) Ubuso obusezantsi besiphelo sesitulo sevalve kunye nobuso obungasentla besiphelo somkhono weplunger zenziwe ngokuchanekileyo ngoomatshini kwaye zingena ngokuqinileyo. Iqiniswe yi-clamping nut kunye ne-torque ecacisiweyo yokuqinisa. Kukho igasket yobhedu yokutywina yoxinzelelo oluphezulu yobunzima obuthile phakathi kwentongomane yokubambelela kunye nesitulo sevalvu. Kukwakho negasket yokutywina enoxinzelelo oluphantsi phakathi kwevalve yokuhambisa i-clamping nut kunye nobuso obuphezulu bendlu.

(4) Isinciphisi esifakwe kwi-grooved ifakwe kwi-cango yangaphakathi yevalve yokuhambisa i-oyile yokuhambisa i-oyile ukunciphisa umthamo wesithuba somngxuma wangaphakathi, ukukhuthaza ukutshiza ngokukhawuleza kunye nokuyeka, kunye nokunciphisa ukuphakama okuphezulu kwevalve yokuhambisa.
