IValve yoxinzelelo lwangasemva
UkuSebenza okuPhakamileyo kweNtsimbi yokuNceda kwiValve yoKhuseleko loKhuseleko lweValve yeDosing
Loluphi uhlobo lwevalve yoxinzelelo lwangasemva?
Ivalve yoxinzelelo lwangasemva (iValve yoxinzelelo lwangasemva) luhlobo lwesivalo esisetyenziselwa ukulawula uxinzelelo lolwelo, oluvumela ulwelo ukuba lugcine uxinzelelo oluthile kumbhobho. Iivalvu zoxinzelelo lwangasemva zidla ngokufakelwa ekupheleni kombhobho ukunqanda ukuphuma ngasemva okanye ukuqukuqela kolwelo kumbhobho nokulawula umlinganiselo wokuhamba kunye noxinzelelo lolwelo. Umgaqo osebenzayo wevalve yoxinzelelo lwangasemva kukulawula uxinzelelo lwamanzi ngokulungelelanisa ukuvulwa kwevalve. Xa uxinzelelo kumbhobho lugqithisa ixabiso elibekiweyo, ivalve ivala ngokuzenzekelayo ukuthintela ulwelo ukuba lungabuyeli ngasemva okanye luphinde lujike. Iivalve zoxinzelelo lwangasemva zisetyenziswa kakhulu kwishishini lemichiza, i-petroleum, igesi yendalo, unyango lwamanzi kunye nezinye iindawo.
Uxinzelelo lwangasemva lusebenza njani?
Ivalve yoxinzelelo lwangasemva isetyenziselwa ukulawula indlela yokuhamba kwamanzi kunye noxinzelelo. Isebenza ngokusebenzisa isiphethu okanye ipiston ngaphakathi kwevalve ukuze ulwelo lukwazi ukuqukuqela kwicala elinye ngelixa luthintela ukubuya umva. Xa ulwelo luhamba lusiya kwicala eliya phambili, ivalve iyavuleka kwaye ulwelo lunokudlula ngokukhululekileyo. Xa ulwelo luhamba lusiya kwicala elingasemva, ivalve iyavala kwaye ithintele ulwelo ukuba lungadluli. Ezifezekisa injongo yokulawula indlela yokuhamba kwamanzi kunye noxinzelelo. Kwimveliso yoshishino, i-valve yoxinzelelo lwangasemva isoloko isetyenziselwa ukulawula ukuhamba kunye noxinzelelo kwinkqubo yokubhobhoza ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo.
Yintoni umsebenzi woxinzelelo lwangasemva?
Umsebenzi wayo kukugcina uxinzelelo oluthile lwangasemva okanye ukuthintela ukugeleza ngasemva kwindlela yokubhobhoza. Kwinkqubo ye-liquid okanye i-gas flow, ukuba uxinzelelo kumbhobho lungaphantsi kwexabiso elithile, luya kukhokelela ekuhambeni okujikelezayo kwamanzi okanye igesi, le nto ibizwa ngokuba yi-backflow. I-valve yoxinzelelo lwangasemva inokulungiswa ngokulungelelanisa ukuvulwa kwevalve. Ukuze uxinzelelo kumbhobho lugcinwe ngaphakathi koluhlu oluthile, ngaloo ndlela luthintele ukwenzeka kwezinto ezihamba ngasemva.
Ngaba ivalve ye-throttle ingasetyenziswa njengevalve yoxinzelelo lwangasemva?
Iivalve ze-throttle zingasetyenziswa njengeevalve zoxinzelelo lwangasemva. Kodwa ukusebenza kunye nokusebenza kwabo kusenokungabi kuhle njengevalve yoxinzelelo lwangasemva eyenzelwe ngokukodwa. Ivalve yoxinzelelo lwangasemva kukulawula uxinzelelo kwinkqubo yokubhobhoza ukukhusela uxinzelelo olugqithisileyo ekulimazeni inkqubo. Iivalve ze-Throttle, kwelinye icala, zisetyenziselwa ukulawula ukuhamba kunye noxinzelelo. kunye nesakhiwo sabo kunye nomgaqo-nkqubo wokusebenza zihluke kwezo ze-valve zoxinzelelo lwangasemva. Ngoko ke, ukuba ufuna ukulawula ngokungqongqo uxinzelelo lwangasemva kwinkqubo yokubhobhoza, kuyacetyiswa ukuba ukhethe ivalve yoxinzelelo lwasemva olulungiselelwe ngokukodwa.
