Yintoni umahluko phakathi kweValve yokungabuyi kunye neValve yokujonga

Xa usebenza ngeenkqubo zombhobho, unokuziva rhoqo zombiniivalvu engabuyisiyo (i-NRV)kwayeivalvu yokujongaziyasetyenziswa. Ekuqaleni, zisenokuvakala ngathi ziivalvu ezimbini ezahlukeneyo. Kodwa ngaba ziyafana ngokwenene? ​​Okanye kukho umahluko ofanele ukuphawulwa? Masiwuhlalutye ngokulula.

Yintoni iValve engabuyiyo (i-NRV)

Ivalvu engabuyiyo luhlobo lwevalvu evumela ulwelo—nokuba lulwelo okanye igesi—ukuba luhambe kwicala elinye kuphela. Nje ukuba ukugeleza kume okanye kuzama ukubuya umva, ivalvu ivala ngokuzenzekelayo. Lo msebenzi uthintela ukugeleza kwakhona, okunokonakalisa izixhobo okanye kungcolise imidiya ecocekileyo.

Ii-NRV zisetyenziswa kakhulu kwezi:Iinkqubo zokubonelela ngamanzi ukuthintela ungcoliseko.Iimpompo zokuthintela ukubuya kwamanzi xa ipompo icinyiwe.Iipayipi zoshishino apho ukugcina ukuhamba komoya calanye kubaluleke kakhulu.

Ingongoma ephambili ilula: i-NRV iqinisekisa ukuba ulwelo luya phambili kwaye alubuyeli umva.

Yintoni iValve yokujonga

Ivalvu yokukhangela isebenza ngomgaqo ofanayo. Ikwamisa ukuhamba okungasemva kwaye iqinisekisa ukuba ulwelo luhamba kwicala elinye kuphela. Iivalvu zokukhangela zinokufumaneka phantse kuyo yonke imboni, ukusuka ekucoceni amanzi ukuya kwioyile negesi.

Kukho iintlobo ezahlukeneyo zeevalvu zokujonga, ezifana nezi:Iivalvu zokujonga ukujika (ezinediski ejijekileyo evulekayo okanye evaliweyo).Iivalvu zokujonga ukuphakamisa (iidiski ziphakama okanye zihla xa kuphuma amanzi).Iivalvu zokujonga ibhola (ibhola isebenza njengendlela yokuvala).Iivalvu zokujonga i-wafer (uyilo oluncinci lweendawo ezixineneyo).

Ngoko ke, yintoni umahluko?

Apha kulapho izinto ziba nomdla khona. Inyani yile: ivalvu engabuyisiyo kunye nevalvu yokujonga izinto zizinto ezifanayo. Umahluko omkhulu usekwe kwisigama.

• Ivalvu engabuyisiyo (i-NRV) ligama eliqhelekileyo okanye elichazayo, elisetyenziswa rhoqo kwisiNgesi saseBritane nakwimizi-mveliso enxulumene namanzi.

• Igama elithi Check valve lisetyenziswa kakhulu, ingakumbi kwisiNgesi saseMelika nakwimeko yemizi-mveliso okanye yoomatshini.

Ngoko ke, xa umntu esithi i-NRV, uthetha ngesixhobo esinye omnye umntu anokuthi yi-check valve. Zombini zisebenza injongo enye: ukuthintela ukubuya kwamanzi.
