Khangela umgaqo wokusebenza kwevalvu, ulwahlulo kunye nokufakelwa kwamanyathelo

Isebenza njani ivalve yokukhangela

Ikhangela ivalve isetyenziswe kwinkqubo yombhobho, kwaye umsebenzi wayo oyintloko kukuthintela ukubuyela ngasemva kwe-medium, ukujikeleza okujikelezayo kwempompo kunye ne-motor yayo yokuqhuba, kunye nokukhutshwa kwe-medium kwi-container.

Khangela iivalvu isenokusetyenziswa kwimigca ebonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokunyuka ngaphezu koxinzelelo lwenkqubo engundoqo. Iivalvu zokutshekisha zingasetyenziswa kwimibhobho yemidiya eyahlukeneyo ngokwezinto ezahlukeneyo.

Ivalve yokutshekisha ifakwe kumbhobho kwaye ibe yenye yamacandelo olwelo lombhobho opheleleyo. Inkqubo yokuvula kunye nokuvala i-disc ye-valve ichaphazelekayo yimeko yokuhamba kwexeshana lenkqubo apho ikhoyo; ngokulandelelana, iimpawu zokuvala zediskhi yevalvu zinefuthe kwimeko yokuhamba kwamanzi.

Jonga ulwahlulo lwevalvu

1. Ivalve yokujonga ujingi

I-disc yevalve yokujonga i-swing ikwimo yediski kwaye ijikeleza i-shaft yesitulo sesitulo sevalve. Ngenxa yokuba umjelo okwi-valve ulungelelaniswa, ukuchasana kokuhamba kuncinci kunoko kwe-valve yokukhangela i-valve. Ifanelekile kumazinga okuhamba okuphantsi kunye neenguqu ezingaqhelekanga zokuhamba. Nangona kunjalo, ayifanelekanga ukuhamba kwe-pulsating, kwaye ukusebenza kwayo kokutywinwa akufani nohlobo lokuphakamisa.

Ivalve yokukhangela i-swing yahlulwe yaba ziindidi ezintathu: uhlobo lwe-lobe enye, uhlobo lwe-lobe oluphindwe kabini kunye nohlobo lwe-lobe ezininzi. Ezi fomu zintathu zahlulwe ubukhulu becala ngokwedayamitha yevalvu.

2. Phakamisa ivalve yokukhangela

Ivalve yokukhangela apho idiski yevalve islayidi ecaleni kombindi othe nkqo womzimba wevalvu. Ivalve yokukhangela i-lift ingafakwa kuphela kumbhobho othe tye, kwaye ibhola ingasetyenziselwa i-disc yevalve kwivalve yokukhangela i-high-pressure encinci ye-diameter. Ubume bomzimba wevalve yevalve yokukhangela i-lift iyafana naleyo yevalve yeglowubhu (inokusetyenziswa ngokufanayo nevalve yeglowubhu), ngoko ke i-coefficient yayo yokumelana nolwelo inkulu. Ubume bayo bufana nevalve yeglowubhu, kwaye umzimba wevalve kunye nediski ziyafana nevalve yeglowubhu.

3. Ivalve yokukhangela ibhabhathane

Ivalve yokutshekisha apho idiskhi ijikeleza kwiphini esitulweni. I-valve yokujonga i-disc inesakhiwo esilula kwaye inokufakwa kuphela kumbhobho othe tye, kwaye ukusebenza kokutywinwa kubi.

4. Ivalve yokukhangela umbhobho

Ivalve apho idiski islayidi ecaleni kombindi womzimba wevalvu. Ivalve yokukhangela umbhobho yivalve entsha. Incinci ngobukhulu, ilula ngobunzima kwaye ilungile kubuchwephesha bokucubungula. Ngomnye wemigaqo yophuhliso lwevalve yokutshekisha. Nangona kunjalo, i-coefficient yokumelana nolwelo inkulu kancinane kunaleyo yevalve yokujonga ujingi.

5. Ivalve yokujonga ukunyanzeliswa

Olu hlobo lwevalve lusetyenziswa njengebhoyila yokutyisa amanzi kunye nevalve yokusikwa komphunga, inomsebenzi odityanisiweyo wevalve yokukhangela yokuphakamisa kunye nevalve yeglowubhu okanye ivalve ye-engile.

Ukongezelela, kukho ezinye iivalve zokujonga ezingafanelekanga ukufakwa kwempompo yepompo, njenge-valve yeenyawo, uhlobo lwentwasahlobo, uhlobo lwe-Y, njl.
