Umgaqo wokusebenza wevalve yokutshekisha.

Iivalve zokukhangela zingasetyenziselwa kwimibhobho apho uxinzelelo kwinkqubo yokuncedisa inokunyuka ngaphezu koxinzelelo lwenkqubo.Khangela iivalvuzingahlelwa ikakhulu kwiivalvu zokujonga ujingi (ezijikeleza kumbindi womxhuzulane) kwaye ziphakamise iivalvu zokujonga (ezihamba nge-axis).

Umsebenzi wolu hlobo lwe-valve yokutshekisha kukuvumela ukuba i-medium ihambe kwicala elinye kuphela kwaye ithintele ukuhamba okubuyela emuva. Ngesiqhelo, le valve isebenza ngokuzenzekelayo. Ngaphantsi koxinzelelo lwe-fluid ehamba kwicala elinye, i-disc valve ivula; xa ulwelo luqukuqela kwelinye icala, uxinzelelo lolwelo kunye nobunzima bokuzimela bediski yevalve busebenza kwisitulo sevalve, ngaloo ndlela kunqunyulwa ukuhamba.

Ivalve yokukhangela lolunye uhlobo olunjalo lwevalve. Ibandakanya iivalve zokujonga ujingi kunye neevalvu zokukhangela zokuphakamisa. Ivalve yokujonga ujingi inomatshini wehenjisi kunye nediski yevalve ephumla ngokukhululekileyo kumphezulu wesihlalo sevalve ethambekele njengomnyango. Ukuqinisekisa ukuba idiski yevalve inokuhlala ifikelela kwindawo efanelekileyo kwisihlalo sevalve ngalo lonke ixesha, idiski yevalve iyilwe ngendlela yehinge ukwenzela ukuba idiski yevalve ibe nesithuba esaneleyo sokujinga kwaye inokuqhagamshelana ngokwenyani nangokupheleleyo nesitulo sevalve. I-disc yevalve inokwenziwa ngokupheleleyo ngetsimbi okanye inokuba nesikhumba, irabha, okanye isigqubuthelo sokwenziwa esalaminated kuyo, kuxhomekeke kwiimfuno zokusebenza.

Xa ivalve yokukhangela i-swing ivuleke ngokupheleleyo, uxinzelelo lwe-fluid luphantse lungathintelwa, ngoko ke ukuhla koxinzelelo kwivalve kuncinci. I-disc yevalve yokukhangela i-lift ibekwe kwindawo yokutywina yesihlalo esiphezulu sevalve yomzimba. Le valve, ngaphandle kokuvumela i-disc ukuba iphakame ngokukhululekile kwaye iwe, inesakhiwo esifanayo ne-valve yokumisa. Uxinzelelo lwe-fluid lubangela ukuba i-disc iphakamise ukusuka kwindawo yokutywina yesihlalo sevalve, kwaye ukubuya kwe-medium kubangela ukuba i-disc ibuyele kwisihlalo sevalve kwaye inqumle ukuhamba.

Ngokuxhomekeke kwiimeko zokusebenza, i-disc ye-valve ingaba yesakhiwo sesinyithi esipheleleyo okanye ngendlela yerabha okanye i-rubber ring efakwe kwi-disc ye-valve. Njengevalve yokumisa, indlela yokuhamba yevalve yokujonga i-lift nayo incinci, ngoko ke ukuhla koxinzelelo kwivalve yokukhangela i-lift kukhulu kune-valve yokujonga i-swing, kwaye umda wokuhamba kwevalve yokujonga ujingi uncinci kakhulu.
