Ivalve yeglowubhu ye-NSW API 602, indawo yokuvula kunye neyokuvala yevalve yesango yentsimbi emkhiweyo yebhonethi yebholiti lisango.Indlela yokuhamba yesango i-perpendicular ukuya kwicala le-fluid.Ivalve yesango yentsimbi ekhandiweyo inokuvulwa ngokupheleleyo kwaye ivalwe kuphela, kwaye ayikwazi ukulungiswa kunye ne-throttled.Isango levalve yesango yentsimbi ekhandiweyo ineendawo ezimbini zokutywina.Imiphezulu emibini yokutywina eyona ndlela ixhaphakileyo yevalve yesango yenze imilo ye-wedge, kwaye i-engile ye-wedge iyahluka ngokweeparamitha zevalvu.Iindlela zokuqhuba iivalvu zesango zentsimbi ezibunjiweyo zezi: manual, pneumatic, electric, gas-liquid linkage.
Umphezulu wokutywina wevalve yesango yentsimbi ekhandiweyo unokutywinwa kuphela ngoxinzelelo oluphakathi, oko kukuthi, uxinzelelo oluphakathi lusetyenziselwa ukucinezela indawo yokutywina yesango ukuya kwisihlalo sevalve kwelinye icala ukuze kuqinisekiswe indawo yokutywina. ukuzitywina.Uninzi lwee-valve zesango zinyanzeliswa ukuba zitywinwe, oko kukuthi, xa i-valve ivaliwe, kuyimfuneko ukunyanzela iplati yesango ngokuchasene nesihlalo se-valve ngamandla angaphandle ukuqinisekisa ukutywinwa kwendawo yokutywina.
Isango levalve yesango lihamba ngokulandelelana kunye nesiqu sevalve, ebizwa ngokuba yivalve yesango lokuphakamisa intonga (ekwabizwa ngokuba yivalve yesango evulekileyo).Ngokuqhelekileyo kukho intambo ye-trapezoidal kwintonga yokuphakamisa.I-nut ishukuma ukusuka phezulu kwevalve kunye negroove yesikhokelo kumzimba wevalve ukutshintsha intshukumo ejikelezayo ibe sisindululo somgca, oko kukuthi, itorque yokusebenza ibe yityholo lokusebenza.
Izinto eziluncedo kwivalve yesango yentsimbi ekhandiweyo:
1. Ukuxhathisa ulwelo oluphantsi.
2. Amandla angaphandle afunekayo ekuvuleni nasekuvaleni amancinci.
3. Umkhombandlela wokuhamba kwendlela ophakathi awuthintelwanga.
4. Xa ivuleke ngokupheleleyo, ukhukuliseko lomphezulu wokutywina ngophakathi osebenzayo luncinane kunolo lwevalve yeglowubhu.
5. Ubume bulula kwaye inkqubo yokuphosa ilungile.
