Stainless Simbi Gedhi Valve

Iyo yekuvhura uye yekuvhara chikamu chesimbi isina simbi yegedhi valve igedhi, uye mafambiro egedhi ari perpendicular kune kutungamira kwemvura. Gedhi resimbi isina tsvina rine zvisimbiso zviviri. Nzvimbo mbiri dzekuisa chisimbiso dzeinonyanya kushandiswa modhi yevharuvhu inoumba wedge, uye wedge angle inosiyana nemaparamita evharuvhu. Gedhi revhavha yegedhi rejeri rinogona kuitwa rose, rinonzi gedhi rakaoma; inogonawo kugadzirwa gedhi rinogona kuburitsa zvishoma deformation kuvandudza manufacturability uye kubhadhara kutsauka kwechisimbiso chepamusoro angle panguva yekugadzirisa. Ndiro yacho inonzi ghedhi re elastiki. Stainless simbi gedhi vharafu zvinhu zvakakamurwa kuva CF8, CF8M, CF3, CF3M, 904L, Duplex Stainless Steel (4A, 5A, 6A).
Mhando dzesimbi isina tsvina yegedhi mavharuvhu anogona kupatsanurwa kuita wedge gedhi mavharuvhu uye akafanana gedhi mavharuvhu zvichienderana nekuvharika kwechiso kugadziridzwa. Wedge gedhi mavharuvhu anogona kukamurwa kuva: imwe gedhi mhando, mbiri gedhi mhando uye elastic gedhi mhando; parallel gedhi mhando gedhi vharafu Inogona kukamurwa kuva imwe gedhi mhando uye mbiri gedhi mhando. Yakakamurwa zvichienderana nenzvimbo yeshinda yehunde yevharuvhu, inogona kukamurwa kuita mhando mbiri: yakavhurika stem gedhi vharafu uye yakasviba stem gedhi vharafu. Rudzi urwu rwevharuvhu kazhinji runofanira kuisirwa yakatwasuka mupombi.
Kana iyo valve yakavhurwa, apo kusimudza kukwirisa kwegedhi kwakaenzana ne1: 1 nguva yevhavha yevhavha, nzira yemvura inenge isina kuvharwa zvachose, asi nzvimbo iyi haigoni kuongororwa panguva yekushanda. Mukushandiswa chaiko, iyo yepamusoro yevhavha stem inoshandiswa sechiratidzo, ndiko kuti, nzvimbo iyo isingagoni kuvhurwa, senzvimbo yayo yakazaruka zvakakwana. Kuti utarise chiitiko chekuvhara nekuda kwekushanduka kwekushisa, vharafu inowanzovhurwa kune apex chinzvimbo uye yozodzoserwa kumashure ne 1/2 kusvika 1 kutendeuka seyakazara yakazaruka valve nzvimbo. Nokudaro, nzvimbo yakazaruka yakakwana yevhavha inotarirwa nenzvimbo yegedhi (kureva sitiroko).
Mune mamwe mavharuvhu egedhi, stem nut inogadzika pagedhi, uye kutenderera kwegumbo remaoko kunotyaira kutenderera kwechitsigiro chevhavha kusimudza gedhi. Rudzi urwu rwevharuvhu inodaidzwa kuti vheruvha yegedhi rinotenderera kana kuti vharafu regedhi rakasviba.
