Umahluko omkhulu phakathi kwevalve yokunciphisa uxinzelelo kunye nevalve yokhuseleko

1. I-valve yokunciphisa uxinzelelo yi-valve eyanciphisa uxinzelelo lwe-inlet kuxinzelelo oluthile olufunekayo lokuphuma ngohlengahlengiso, kwaye ithembele kumandla ophakathi ngokwawo ukugcina ngokuzenzekelayo uxinzelelo oluzinzileyo lokuphuma.Ukusuka kwimbono ye-fluid mechanics, i-valve yokunciphisa uxinzelelo yinto ephazamisayo enokuthi ukuchasana kwayo kwendawo kungatshintshwa, oko kukuthi, ngokuguqula indawo ye-throttling, i-flow velocity kunye ne-kinetic energy ye-fluid iyatshintshwa, kubangele uxinzelelo oluhlukeneyo. ilahleko, ukuze kuphunyezwe injongo yokuthomalalisa.Emva koko uthembele ekuhlengahlengisweni kwenkqubo yokulawula kunye nokulawula ukulungelelanisa ukuguquguquka kwengcinezelo ye-post-valve kunye ne-spring force, ukwenzela ukuba uxinzelelo lwe-post-valve luhlala luhlala luhlala ngaphakathi kwinqanaba elithile lephutha.

2. Ivalve yokhuseleko yindawo yokuvula kunye nokuvala ekwimeko evaliweyo ngokuqhelekileyo phantsi kwesenzo samandla angaphandle.Xa uxinzelelo oluphakathi kwisixhobo okanye umbhobho lukhuphuka ngaphezu kwexabiso elichaziweyo, liya kuthintela uxinzelelo oluphakathi kwipayipi okanye izixhobo ezingaphezulu kwexabiso elichaziweyo ngokukhupha i-medium ukuya ngaphandle kwenkqubo.iivalve ezikhethekileyo.Iivalve zokhuseleko ziyi-valve ezizenzekelayo, ezisetyenziswa kakhulu kwiibhoyili, iinqanawa zoxinzelelo kunye nemibhobho, ukulawula uxinzelelo lokungadluli ixabiso elichaziweyo, kwaye lidlale indima ebalulekileyo ekukhuseleni ukhuseleko lomntu kunye nokusebenza kwezixhobo.

2. Umahluko omkhulu phakathi kwevalve yokunciphisa uxinzelelo kunye nevalve yokhuseleko:
1. I-valve yokunciphisa uxinzelelo sisixhobo esinciphisa i-medium kunye noxinzelelo oluphezulu ukuya phakathi kunye noxinzelelo oluphantsi.Uxinzelelo kunye namaxabiso obushushu aphakathi koluhlu oluthile.
2. Iivalve zokukhusela zisetyenziselwa ukukhusela iibhoyili, iinqanawa zoxinzelelo kunye nezinye izixhobo okanye iipayipi ukuba zonakaliswe ngenxa yoxinzelelo olugqithisileyo.Xa uxinzelelo luphezulu kancinci kunoxinzelelo oluqhelekileyo lokusebenza, ivalve yokhuseleko iya kuvula ngokuzenzekelayo ukunciphisa uxinzelelo.Xa uxinzelelo lungaphantsi kancinci kunoxinzelelo oluqhelekileyo lokusebenza, ivalve yokhuseleko izivala ngokuzenzekelayo, iyeke ukukhupha ulwelo kwaye igcine ukutywinwa.Ukubeka nje, i-valve yokukhusela kukuthintela uxinzelelo lwenkqubo ekugqithiseni ixabiso elithile, kwaye lisetyenziselwa ukukhusela inkqubo.I-valve yokunciphisa uxinzelelo kukunciphisa uxinzelelo lwenkqubo ukusuka kuxinzelelo oluphezulu ukuya kwixabiso elifunwayo, kwaye uxinzelelo lwayo lokuphuma lungaphakathi kuluhlu, ngokude nje lungaphakathi kolu luhlu.
3. Ivalve yokhuseleko kunye nevalve yokunciphisa uxinzelelo ziintlobo ezimbini zeevalve, eziziivalve ezikhethekileyo.Phakathi kwabo, i-valve yokhuseleko yesixhobo sokukhulula ukhuseleko , okuyi-valve ekhethekileyo, eyenza kuphela xa uxinzelelo olusebenzayo ludlula uluhlu oluvumelekileyo, kwaye ludlala indima yokukhusela kwinkqubo.I-valve yokunciphisa uxinzelelo yi-valve yenkqubo enokuthi i-decompress-high-pressure logistics ukuhlangabezana neemfuno zoxinzelelo lwenkqubo emva kokucubungula.Inkqubo yokusebenza kwayo iyaqhubeka.
