Zithini izizathu zokusilela kokutywina kwe-valves yesango?

Ukusilela kokutywina kwendlelaI-valves yesangoIbangelwa ikakhulu kwezi zizathu zilandelayo:

Into yokutywina komhlaba

Nxiba kunye nokukrazula: Ukuvula rhoqo nokuvalwa kwesango, ukuxabana kwexesha elide phakathi kwendawo yokutywina, kuya kuthi ngokuthe ngcembe kusekho umbandela wokutywina, okukhokelela ekunciphiseni kwendlela yokutywina. Umzekelo, kwimibhobho ihambisa imithombo yeendaba enamasuntswana anengqiqweni, amasuntswana aya kwandisa ukunxila komgangatho wokutywina.

I-Colososion: Ukuba i-Medium iyaphambuka, iyakukubangela ukhukuliseko lwekhemikhali kumhlaba wokutywina, ukonakalisa isakhiwo kunye nokusebenza kwezinto zokutywina komhlaba. Imithombo yeendaba enamandla kunye ne-Alkali inokubangela ukuba i-fake kwaye ivele i-corosion kumgangatho wesinyithi wokutywina, echaphazela isiphumo sokutywina.

Umonakalo: Ngexesha lokufakwa, ukuthutha, okanye ukusetyenziswa, umphezulu wokutywina unokwenzakala yimikhosi yangaphandle enjengokungqubana, ukutyhoboza, njl njl.

I-valve isitulo kunye nemiba yesango

Isihlalo seVove seVulve: Ukuba unxibelelwano phakathi kwesihlalo sevali kunye nebhunga le-vali lingayikhululi phantsi kwesenzo soxinzelelo oluphakathi kwaye sibangele ukungaphumeleli.

Isiphoso seSango: Xa isango liphantsi komkhosi ongalinganiyo okanye ubushushu obuphezulu, unokuyifumana, ibangela isango lokungalingani ngesihlalo sevali kwaye sibangelwa kukuvuza. Umzekelo, ukuba aI-Palve yesangoIsebenza ixesha elide phantsi kweemeko zobushushu obuphezulu, isango lingafikelela ngenxa yokwanda okungalinganiyo.

Ukusebenza okungafanelekanga kunye nokugcinwa

Ukuvalwa okungaphelelanga: Umqhubi akazange anciphise ngokupheleleyo i-valve yesango xa uvale, okukhokelela kwizithuba eziphakathi komgangatho wokutywina kwaye ubangele ukuvuza okuphakathi.

Ukunqongophala kokulungiswa: Ukunqongophala kwexesha elide lokugcinwa kwesondlo kunokukhokelela ekuqokeleleni okungcolileyo, ubumdaka, njl njl. NgaphakathiI-Palve yesango, echaphazela ukusebenza kwento yokutywina komgangatho wokutywina. Ngeli xesha, ukunqongophala kokuhlolwa rhoqo kunye nokutshintshwa kwamatywina kunokukhokelela ekunciphiseni kwendlela yokutywina.

Impembelelo yeempawu eziphakathi

Ingcinezelo yoxinzelelo: Ukuguquguquka rhoqo kuxinzelelo oluphakathi kunokubangela imikhosi yempembelelo engazinzanga esangweni, echaphazela ukutywinwa kwetywina phakathi kwesango kunye nesihlalo se-vale, esikhokelela ekungaphumlweni kwetywina.

Ukwahluka kweqondo lobushushu: Umaqondo wobushushu okutshintsha kwe-Prium unokubangela ukwanda kwe-shirium kunye nokwahlulahlula izinto ezahlukeneyo zevalve yesango. Ukuba i-coefficents ekwandisiweyo yecandelo ngalinye lahlukile, uxinzelelo lwe-thermal luya kwenziwa, lukhokelela ekungcungcuthekise okanye ukukhululeka kumgangatho wokutywina kwaye uchaphazele ukusebenza kokutywina.
