Ukusebenza

ivalve yokhuseleko esetyenziselwa ukulawula okanye ukunciphisa uxinzelelo kwinkqubo; Uxinzelelo lunokwakha kwaye ludale inkqubo ephazamisekileyo, isixhobo okanye ukusilela kwesixhobo, okanye umlilo. Uxinzelelo luyancipha ngokuvumela i-pressurized fluid ukuba ihambe ukusuka kwindawo encedisayo ngaphandle kwenkqubo. I-valve yokunceda yenzelwe okanye imiselwe ukuvula kwi-predetermined set pressure ukukhusela iinqanawa zoxinzelelo kunye nezinye izixhobo ezixhomekeke kwiingcinezelo ezidlula imida yazo yokuyila. Xa uxinzelelo olumiselweyo lugqithiswa, i-valve yokunceda iba "indlela yokunganyangeki" njengoko i-valve inyanzeliswa ukuba ivuleke kwaye inxalenye ye-fluid iguqulwa ngendlela yokuncedisa. Ulwelo olujikiweyo (ulwelo, irhasi okanye umxube werhasi engamanzi) ludla ngokuhanjiswa ngenkqubo yemibhobho eyaziwa njengentloko yokudangala okanye iheader yokunceda ukuya kumbindi, amadangatye erhasi aphezulu apho aqhele ukutshiswa khona zize iigesi ezitsha eziphumayo zikhutshelwe emoyeni. . Njengoko ulwelo luguqulwa, uxinzelelo olungaphakathi kwinqanawa luya kuyeka ukunyuka. Nje ukuba ifikelele kuxinzelelo lwevalve yokubuyisela kwakhona, ivalve iya kuvala. I-blowdown idla ngokuchazwa njengepesenti yoxinzelelo olusetiweyo kwaye ibhekisela kwindlela yoxinzelelo olufuna ukuhla ngayo ngaphambi kokuba i-valve iphinde ibuyele. I-blowdown inokwahluka malunga ne-2-20%, kwaye ezinye iivalvu zinee-blowdowns ezilungelelanisiweyo.
