Isimiso sokusebenza kanye nezici ze-Globe Valve.

Isimiso sokusebenza

I-Globe Valve, eyaziwa nangokuthi i-valve yokumisa, ingenye yezinhlobo zama-valve ezisetshenziswa kakhulu. Kuthandwa kakhulu ngoba ngesikhathi sokuvula nokuvala, ukungqubuzana phakathi kwezindawo zokuvala uphawu kuncane, kuqinile, ukuphakama kokuvula akukukhulu, inqubo yokukhiqiza ilula, futhi ukugcinwa kulula. Akufanelekile kuphela ukucindezela okuphakathi nokuphansi, kodwa futhi nokucindezela okuphezulu.

Isimiso sokuvala se-Globe Valve ukuthi isebenzisa ukucindezela kwesileva se-valve ukwenza indawo yokuvala ye-valve disc ihambisane eduze nendawo yokuvala yesihlalo se-valve, ngaleyo ndlela ivimbele ukugeleza kwe-medium.

I-Globe Valve ivumela i-medium ukuthi igeleze iye ohlangothini olulodwa futhi inesidingo sokuqondisa ngesikhathi sokufakwa. Ubude besakhiwo se-I-I-I-Globe Valveyinde kunaleyo ye-Gate Valve. Ngesikhathi esifanayo, ukumelana noketshezi kuphezulu, futhi ukwethembeka kokuvala uphawu akunamandla esikhathini eside sokusebenza.

Izici

(1)Isakhiwo se-I-I-I-Globe Valveilula kunaleyo ye-Gate Valve, futhi kokubili ukukhiqiza nokunakekela kulula kakhulu.

(2) Indawo yokuvala ayijwayele ukugqokwa noma ukunwaya. Inokusebenza okuhle kakhulu kokuvala. Phakathi nenqubo yokuvula nokuvala, asikho isihlobo esishelelayo phakathi kwe-disc ye-valve kanye nendawo yokuvala ye-valve yomzimba. Ngakho-ke, ukugqoka noma ukuklwebheka akunzima, futhi ukusebenza kokuvala kuhle ngempilo ende yesevisi.

(3) Ngesikhathi sokuvula nokuvala, i-stroke yediski ye-valve incane, ngakho ukuphakama kwe-Globe Valve kuncane kunokwe-Sango Valve, kodwa ubude bayo besakhiwo bude kunobu-Valve Yesango.

(4) Itorque yokuvula neyokuvala inkulu, okwenza ukuhlinzwa kube nzima futhi kuthatha isikhathi eside.

(5) Ukumelana noketshezi oluphezulu. Ngenxa yendlela ehlukumezayo ye-medium emzimbeni we-valve, ukumelana noketshezi kuphezulu, okuholela ekusetshenzisweni kwamandla okuphawulekayo.

(6) Uma i-PN yengcindezi ebizwa ngokuthi i-Medium flow direction ingu-≤ 16 MPa, ukugeleza okujwayelekile kuya phezulu kusuka phansi kwe-valve disc; lapho ingcindezi ebizwa ngokuthi i-PN ingu-≥ 20 MPa, isiqondiso esivamile sokugeleza siyehla sisuka phezulu kwe-valve disc. Lokhu kwenzelwa ukuthuthukisa ukusebenza kokuvala uphawu. Ngesikhathi sokusetshenziswa, i-medium ye-Globe Valve ingageleza ohlangothini olulodwa kuphela futhi ayikwazi ukushintsha isiqondiso sokugeleza.

(7) Uma ivuliwe ngokugcwele, i-valve disc ivame ukuguguleka.

I-axis ye-valve stem ye-Globe Valve incike endaweni yokuvala yesihlalo se-valve. I-stroke yokuvula noma ukuvala i-valve imfushane kakhulu, futhi inesenzo sokusika esithembeke kakhulu, okwenza lolu hlobo lwe-valve lufanelekele ukusetshenziswa njenge-cut-off noma i-regulation and throttling of the medium.
