Umgaqo wokusebenza kunye neempawu zeGlobe Valve.

Umgaqo wokusebenza

Ivalve yeGlobe, ekwabizwa ngokuba sisivalo sokumisa, yenye yezona ntlobo zisetyenziswa kakhulu zeevalvu. Idume kakhulu kuba ngexesha lokuvula kunye nokuvala inkqubo, ukungqubuzana phakathi kweendawo zokutywina kuncinci, kunqabile, ukuphakama kokuvula akukhulu, inkqubo yokuvelisa ilula, kwaye ukugcinwa kukulungele. Akufanelekanga kuphela kuxinzelelo oluphakathi kunye oluphantsi, kodwa kunye noxinzelelo oluphezulu.

Umgaqo wokuvala weGlobe Valve kukuba usebenzisa uxinzelelo lwevalve ukwenza indawo yokutywina yediski yevalve ibambelele ngokusondeleyo kumphezulu wokutywina wesihlalo sevalve, ngaloo ndlela ithintele ukuhamba kwesixhobo.

I-Valve ye-Globe ivumela kuphela i-medium ukuba ihambe kwicala elinye kwaye ineemfuno zesikhokelo ngexesha lofakelo. Ubude besakhiwo seIvalve yeglowubhuinde kunaleyo yeGalufa yeSango. Ngexesha elifanayo, ukuchasana kwamanzi kuphezulu, kwaye ukuthembeka kwayo kokutywinwa akunamandla ngexesha elide lokusebenza.

Iimpawu

(1)Ubume beIvalve yeglowubhuilula kunaleyo yeValve yeSango, kwaye zombini ukuvelisa kunye nokugcinwa kulula ngakumbi.

(2) Umphezulu wokutywina awuthandeki ukunxiba okanye ukukrwela. Inomsebenzi obalaseleyo wokutywina. Ngethuba lokuvula kunye nenkqubo yokuvala, akukho silawuli esihlobene phakathi kwe-disc ye-valve kunye nokutywinwa kwendawo yomzimba. Ke ngoko, ukunxiba okanye ukukrwela kubukhali, kwaye ukusebenza kokutywina kulungile kunye nobomi benkonzo ende.

(3) Ngethuba lokuvula kunye nokuvala, i-stroke ye-disc ye-valve incinci, ngoko ukuphakama kwe-Globe Valve kuncinci kunomGangatho weSango, kodwa ubude bayo besakhiwo bude kunobu-Valve yeSango.

(4) Itorque yokuvula nokuvala inkulu, nto leyo eyenza umsebenzi ube nzima kwaye uthabathe ixesha elide.

(5) Ukuxhathisa ulwelo oluphezulu. Ngenxa yendlela enzima ye-medium kumzimba wevalve, ukuxhathisa ulwelo kuphezulu, okukhokelela ekusetyenzisweni okubalulekileyo kwamandla.

(6) Xa i-PN ye-PN yoxinzelelo lwegama lokuhamba kwe-medium flow direction ≤ 16 MPa, ulwalathiso oluqhelekileyo lokuhamba luya phezulu ukusuka ezantsi kwe-valve disc; xa i-PN yoxinzelelo lwegama ≥ 20 MPa, indlela yokuhamba eqhelekileyo ihla ukusuka phezulu kwidiski yevalve. Oku kukwandisa ukusebenza kokutywinwa. Ngexesha lokusetyenziswa, i-medium ye-Globe Valve inokuhamba kuphela kwicala elinye kwaye ayikwazi ukutshintsha indlela yokuhamba.

(7) Xa ivuleke ngokupheleleyo, idiskhi yevalve ihlala iphantsi kokhukuliseko.

I-axis ye-valve stem ye-Globe Valve i-perpendicular kumphezulu wokutywina wesihlalo sevalve. I-stroke yokuvula okanye ukuvala i-valve ifutshane, kwaye inesenzo sokusika esithembeke kakhulu, okwenza olu hlobo lwevalve lulungele ukusetyenziswa njenge-cut-off okanye ummiselo kunye ne-throttling ye-medium.
