Uyazi yini izigaba ezivamile zamavalvu ebhabhathane kagesi?

Amavalvu ebhabhathane kagesiuhlobo lwevalvu kagesi kanye nevalvu yokulawula kagesi. Izindlela eziyinhloko zokuxhumanisa kagesiamavalvu ebhabhathaneyilezi: uhlobo lwe-flange kanye nohlobo lwe-wafer; izinhlobo eziyinhloko zokuvalaamavalvu ebhabhathane kagesiyilezi: ukuvalwa kwerabha kanye nokuvalwa kwensimbi.

Ugesiivalvu yebhabhathaneilawula ukuvulwa nokuvalwa kwevalvu yebhabhathane ngamasignali kagesi. Lo mkhiqizo ungasetshenziswa njengevalvu yokuvala, ivalvu yokulawula kanye nevalvu yokuhlola ezinhlelweni zamapayipi. Ifakwe idivayisi yokulawula ngesandla. Uma kwenzeka ugesi uphela, ingasetshenziswa okwesikhashana ngesandla ukuze igweme ukuthinta ukusetshenziswa kwayo.

Ukuhlukaniswa ngesimo sesakhiwo

(1) Uphawu oluphakathi

Oyedwaivalvu yebhabhathane kagesi yokuvala engavamile.

(3)I-valve kagesi yebhabhathane ephindwe kabili eyisivikelo.

(4) Ivalvu kagesi yebhabhathane evalwe nge-offset ezintathu.

2. Ukuhlukaniswa ngokuvala izinto ezingaphezulu

(1) Ipheya lokuvala uphawu oluthambile lakhiwe ngezinto ezithambile ezingezona ezensimbi ezimelene nezinto ezithambile ezingezona ezensimbi. Ipheya lokuvala uphawu lakhiwe ngezinto eziqinile zensimbi ezimelene nezinto ezithambile ezingezona ezensimbi.

(2) Ivalvu yebhabhathane kagesi enesivalo esiqinile sensimbi. Ipheya lokuvala lakhiwe ngezinto eziqinile zensimbi ezimelene nezinto eziqinile zensimbi.

3. Ukuhlukaniswa ngefomu lokuvala

(1) Ukuvalwa okuphoqelelwe: Ivalvu kagesi yebhabhathane evala ngokunwebeka. Ingcindezi ethile yokuvala ikhiqizwa yipuleti yevalvu ecindezela isihlalo sevalvu lapho ivalvu kagesi ivaliwe, kanye nokuqina kwesihlalo sevalvu noma ipuleti levalvu. Ivalvu kagesi yebhabhathane evala ngokunwebeka yangaphandle, ingcindezi ethile yokuvala ikhiqizwa yi-torque esetshenziswa kushafu wevalvu.

(2) Ivalvu kagesi yebhabhathane yokuvala ecindezelwe: Ingcindezi ethile yokuvala ikhiqizwa ngokucindezela into yokuvala enwebekayo esihlalweni sevalvu noma epuletini levalvu.

(3) I-valve kagesi ye-butterfly yokufaka uphawu ngokuzenzakalelayo: Ingcindezi ethile yokufaka uphawu ikhiqizwa ngokuzenzakalelayo yingcindezi ephakathi nendawo.
