1. I-valve yokunciphisa ingcindezi iyi-valve enciphisa ukucindezela kokungena kungcindezi ethile edingekayo yokuphuma ngokulungiswa, futhi incike emandleni omthombo ngokwawo ukuze kugcinwe ngokuzenzakalelayo ukucindezela kokuphuma okuzinzile.Ngokombono we-fluid mechanics, i-valve yokunciphisa ingcindezi iyisici esicindezelayo lapho ukumelana kwayo kwendawo kungashintshwa, okungukuthi, ngokushintsha indawo yokudonsa, isivinini sokugeleza kanye namandla e-kinetic oketshezi kuyashintshwa, okuholela ekucindezelweni okuhlukile. ukulahlekelwa, ukuze kuzuzwe inhloso yokuwohloka komqondo.Bese uthembele ekulungisweni kwesistimu yokulawula nokulawula ukulinganisa ukuguquguquka kokucindezela kwe-post-valve namandla asentwasahlobo, ukuze ukucindezela kwe-post-valve kuhlale kungashintshi phakathi kwebanga elithile lephutha.
2. I-valve yokuphepha iyingxenye yokuvula neyokuvala esesimweni esivalekile esivalekile ngaphansi kwesenzo samandla angaphandle.Lapho ingcindezi ephakathi nendawo emshinini noma epayipini ikhuphuka ngaphezu kwenani elishiwo, izovimbela ukucindezela okuphakathi epayipini noma okokusebenza ukuba kudlule inani elishiwo ngokukhipha okuphakathi kuya ngaphandle kwesistimu.ama-valve akhethekile.Ama-valve okuphepha angama-automatic valves, ikakhulukazi asetshenziswa kuma-boilers, imikhumbi yokucindezela kanye namapayipi, ukulawula ingcindezi yokungeqi inani elishiwo, futhi adlale indima ebalulekile ekuvikeleni ukuphepha komuntu siqu nokusebenza kwemishini.
2. Umehluko omkhulu phakathi kwe-valve yokunciphisa ukucindezela kanye ne-valve yokuphepha:
1. I-valve yokunciphisa ingcindezi iyisisetshenziswa esinciphisa i-medium ne-high pressure kuya emaphakathi enomfutho ophansi.Amanani okucindezela nezinga lokushisa angaphakathi kwebanga elithile.
2. Ama-valve okuphepha ama-valve asetshenziselwa ukuvimbela ama-boilers, imikhumbi yokucindezela nezinye izinto zokusebenza noma amapayipi ukuba angalinyazwa ngenxa yokucindezela ngokweqile.Uma ingcindezi iphakeme kancane kunokucindezela okujwayelekile kokusebenza, i-valve yokuphepha izovuleka ngokuzenzakalelayo ukunciphisa ukucindezela.Uma ingcindezi ingaphansi kancane kunomfutho ojwayelekile wokusebenza, ivalvu yokuphepha ivala ngokuzenzakalelayo, iyeke ukukhipha uketshezi futhi iqhubeke ivaleka.Kalula nje, i-valve yokuphepha iwukuvimbela ukucindezela kwesistimu ekudluleleni inani elithile, futhi isetshenziselwa ikakhulukazi ukuvikela uhlelo.I-valve yokunciphisa ingcindezi iwukunciphisa ukucindezela kwesistimu ukusuka kumfutho ophezulu ukuya kunani elifiselekayo, futhi ingcindezi yokuphuma kwayo ingaphakathi kwebanga, inqobo nje uma ingaphakathi kwalolu hlu.
3. I-valve yokuphepha kanye ne-valve yokunciphisa ingcindezi yizinhlobo ezimbili zama-valve, okungama-valve akhethekile.Phakathi kwabo, i-valve yokuphepha ingeyedivayisi yokukhululwa kokuphepha , okuyi-valve ekhethekile, eyenza kuphela lapho ukucindezela kokusebenza kudlula ububanzi obuvunyelwe, futhi idlala indima yokuvikela ohlelweni.I-valve yokunciphisa ingcindezi iyi-valve yenqubo engakwazi ukucindezela izinto zokucindezela okuphezulu ukuze kuhlangatshezwane nezidingo zokucindezela zesistimu yokucubungula emva kokucubungula.Inqubo yayo yokusebenza iyaqhubeka.
