Iimpawu zemveliso
Ngokweemfuno zemeko yokwenyani, ulwakhiwo olusezantsi luyilwe njengodidi olusezantsi olusicaba, kwaye umzimba wevalvu luhlobo lwe-V. Ikwabonelela ngeendlela ezimbini zokusebenza zokunyusa nokuthoba. Umngxuma ongaphakathi womzimba wevalvu uxhotyiswe nge-anti-corrosion neringi yokutywina, enokukhusela umzimba wevalve kukhukuliseko oluphakathi kunye nokudleka ngexesha lokuvulwa. Umsesane wokutywina uphathwa ngokukodwa ukwenza ubunzima bomhlaba bufikelele kwi-hrc56-62, onomsebenzi wokumelana nokugqoka okuphezulu kunye ne-anti-corrosion. Umphezulu wokutywina wediski ye-valve ugqunywe nge-carbide ene-cemented xa kuyimfuneko, kwaye isibini sokutywina samkela isitywina somgca ukuqinisekisa ukuthembeka kwesitywina kunye nokuthintela ukonakala. Ngexesha elifanayo, uyilo lwe-disc ye-stroke emfutshane yamkelwa. Iindlela ezahlukeneyo zokusebenza, ezinje ngemanuwali, ipneumatic (ukubuya kwentwasahlobo, ukusebenza kabini, kunye nangaphandle kwevili lesandla), umbane, ihydraulic, igiya, njl.
