Ukuhlaziywa kwesimiso sokusebenza kwe-valve yokulethwa

I-valve ye-Isovolumetric: ngokuvamile inomphathi okhululayo ukunciphisa ingcindezi.

I-valve ye-Isobaric: ine-valve yokubuyisela uwoyela, engacindezela ngempumelelo umjovo wesibili kanye ne-cavitation ngemuva komjovo.

(1) I-valve yokulethwa kanye nesihlalo se-valve yizingxenye ezifaniswe ngokunemba, ezenziwe ngensimbi ye-alloy yekhwalithi ephezulu. Imbobo yomhlahlandlela, ubuso bokugcina obungenhla naphansi kanye nembobo yesihlalo kucutshungulwa ngokunembile futhi kuphansi, futhi akukwazi ukushintshaniswa ngemva kokufanisa.

(2) Ingxenye eyindilinga yevalvu yokudiliva iyindawo ye-axial sealing cone yevalvu. Ingxenye eyisiyingi ye-valve ishelela embotsheni yomhlahlandlela ukuze iqondise. Umsila wenziwa ngomshini one-groove ukuze wenze isiphambano esimise okwesiphambano ukuze uphethiloli udlule. I-cylindrical surface emaphakathi nevalve yokudiliva ibizwa ngokuthi indawo yokusiza ingcindezi, eyenza ivolumu yokukhulula ingcindezi phakathi kwayo nendawo yekhoni yokuvala.

(3) Ubuso obuphansi bokugcina besihlalo sevalvu kanye nobuso obungaphezulu bomkhono we-plunger bufakwe ngomshini futhi buqina. Iqiniswa i-clamping nut nge-torque ecacisiwe yokuqinisa. Kukhona i-copper high-pressure sealing gasket yogqinsi oluthile phakathi kwe-clamping nut nesihlalo sevalvu. Kukhona futhi i-gasket yokuvala ingcindezi ephansi phakathi kwentongomane yokubopha i-valve kanye nobuso obungaphezulu bendlu.

(4) Isinciphisi esine-grooved sifakwa emgodini ongaphakathi we-valve yokuhambisa uwoyela yokucindezela uwoyela ukuze kuncishiswe umthamo wesikhala somgodi ongaphakathi, sikhuthaze ukufutha ngokushesha futhi simise, futhi sinciphise ukuphakama okuphezulu kwevalvu yokudiliva.
