Ukusebenza

i-valve yokuphepha esetshenziselwa ukulawula noma ukunciphisa ingcindezi ohlelweni;ingcindezi ingase yakheke futhi idale ukuphazamiseka kwenqubo, ukwehluleka kwethuluzi noma okokusebenza, noma umlilo.Ukucindezela kuyadalulwa ngokuvumela uketshezi olucindezelwe ukuthi lugeleze lusuka endaweni eyisiza ngaphandle kwesistimu.I-valve yokusiza iklanyelwe noma isethwe ukuze ivuleke ekucindezelweni okumisiwe okunqunywe kusengaphambili ukuze kuvikelwe imikhumbi yokucindezela nezinye izinto zokusebenza ekubhekaneni nezingcindezi ezidlula imingcele yazo yokuklama.Lapho ukucindezela okuhleliwe kweqiwa, i-valve yokukhulula iba “umzila wokumelana okuncane” njengoba ivalvu iphoqelelwa ukuba ivuleke futhi ingxenye yoketshezi iphambukiswa ngomzila osizayo.Uketshezi oluphambukisiwe (uketshezi, igesi noma ingxube ye-liquid-gas) ngokuvamile luhanjiswa ngesistimu yamapayipi eyaziwa ngokuthi i-flare header noma unhlokweni wokusiza ukuya endaweni ephakathi nendawo ephakeme, lapho ivame ukushiswa khona bese kuthi amagesi avuthayo akhishelwe emkhathini. .Njengoba uketshezi luphambukisa, ukucindezela ngaphakathi komkhumbi kuzoyeka ukunyuka.Uma ifinyelela ukucindezela kwe-valve yokuvuselela kabusha, i-valve izovala.I-blowdown ivame ukushiwo njengephesenti lokucindezela okumisiwe futhi ibhekisela ekutheni ingcindezi idinga ukwehla ngaphambi kokuba i-valve iphinde iqale kabusha.I-blowdown ingahluka kusukela cishe ku-2-20%, kanti amanye ama-valve ane-blowdown elungisekayo.

 

Isicelo:

Isetshenziswa kumishini namapayipi ngamafutha, umoya, amanzi neminye imidiya enezinga lokushisa lokusebenza ≤300℃.
