Kutheni le nto i-valves inqanda i-backflow ephakathi?

'NjengeGqibelelo'-nye "kwiinkqubo zemibhobho,Jonga i-valvevesYiba nomsebenzi ophambili wokunyanzela ukuhamba kwemithombo yeendaba kunye nokuphelisa umngcipheko wokomsa. Esi sibonakaliso sivela kumdibaniso onzulu wokuyilwa kwendlela yayo yendlela kunye nemigaqo-nkqubo yoomatshini.

Ukusuka kwimbono yolwakhiwo, jonga ii-valves eziqhelekileyo ezenziwe nge-disves, izihlalo zeValve, kunye neendlela zokudibanisa (ezinje nge-chinges kunye nemithombo) ngaphakathi. Xa i-Medium ihamba ngendlela eyandulelayo, ingcinezelo ye-fluid ityhila i-dipc isuka kwisitulo sevali, senza itshaneli egudileyo kwaye ivumela i-prium idlule kakuhle; Nje ukuba isikhululo se-verve esiphakathi, i-valve disve ivalve ihamba ngokukhawuleza imvakalisiso yesihlalo kwaye iqinile itywina elidityanisiweyo, lenze indlela ethembekileyo kunye nokusika indlela yokuhamba ngokuhamba. Umzekelo, iveli yokujonga ireyitha efakwe kwindawo yokuphuma kwempompo yamanzi inokuvala ngoko nangoko i-idi ye-vamp xa impompo imisiwe, ithintela ifuthe le-hammer ukusuka ekuhambeni kokuhamba kwamanzi.

Imithetho-siseko yeenkqubo ze-fluid ye-fluid ngakumbi yokuphucula ubuchule bokuphuma kwi-valves yokutshekisha. Xa uqukuqela phambili, uxinzelelo olunamandla lwe-medium lugcina i-idil ye-valve ivulekile, ikhokelela ekuchaseni okuncinci; Xa i-REAL PREARE yenzekile, uxinzelelo lwe-valve displas lupholile, kwaye uxinzelelo lwe-Dowlightream Prevel luyekele i-disver ye-id, ukufezekisa "ukufezekisa" i-sero leakoge "le" lero leakyid ". Le ndlela yokuphendula eguqukayo yenza ukuba i-valves ijonge ngokukhawuleza ukuze iqhelanise nokuxinana, ingakumbi kwiindawo ezinomngcipheko omkhulu njengamashishini eekhemikhali, ukuphepha ngokufanelekileyo umngcipheko wokuxuba okuphakathi okanye ukuqhuma.

Ukuphuculwa kwezinto kunye neenkqubo kukuphucule kakhulu ukuthembeka kweevalva zokujonga. Intsimbi itywinweJonga i-valvezenziwe ngezinto ezinganyangekiyo ezixhaphaza ezingqondweni ezifana nentsimbi engenasitali kunye ne-hastelloy, kwaye zilungele ubushushu obuphezulu kunye nemibhobho yoxinzelelo ephezulu; I-Voves ethambileyo etywiniweyo ifumana i-Airtight Ling Pallight nge-iraber kunye ne-polytetrafluorosene, intlanganiso ukucoceka kokutya kunye namayeza okutya. Ukongeza, uyilo oluncedisiweyo lwentwasahlobo yevatso linokulifihla ixesha lokuvala, kwaye indawo yokuvula ejikelezayo ikhawulezisa ukutywina kwe-centrifugal amandla, ukuqhubela phambili ukusebenza kwe-anti

Kwiinkqubo zempompo zamanzi ukuya kwimibhobho ye-aerospace,Jonga i-valvevesSoloko udlala indima ephambili njenge "jates-nye ngendlela". Ngobuchule bolwakhiwo, ubuchule boomatshini, kunye nokuthathwa kwendlela, kunye nenkqubo yokhuseleko lwezinto ezininzi kwenziwa ukuqinisekisa ukuba ukuhamba ngokungqongqo kulwahlulo olumiselweyo, ukubonelela ngesiqinisekiso esiqinileyo sokukhuseleka kwemizi-mveliso kunye nokuzinza kwenkqubo.
