Maziko osankha choyendetsera magetsi cha valavu ya gulugufe

A. Mphamvu yogwirira ntchito

Mphamvu yogwiritsira ntchito ndiyo gawo lofunika kwambiri posankhavalavu ya gulugufechoyendetsera magetsi. Mphamvu yotulutsa ya choyendetsera magetsi iyenera kukhala yochulukirapo ka 1.2 ~ 1.5 kuposa mphamvu yogwiritsira ntchito yavalavu ya gulugufe.

B. Mphamvu yogwirira ntchito

Pali njira ziwiri zazikulu zogwirira ntchitovalavu ya gulugufe choyendetsera magetsi: imodzi ilibe mbale yopopera, ndipo mphamvu yake imatuluka mwachindunji; inayo ili ndi mbale yopopera, ndipo mphamvu yake imasandulika kukhala mphamvu yopopera kudzera mu nati ya tsinde la valve mu mbale yopopera.

C. Chiwerengero cha matembenuzidwe a shaft yotulutsa

Chiwerengero cha ma turn a output shaft ya valve electric actuator chikugwirizana ndi mainchesi a nominal a valve, pitch ya valve stem, ndi chiwerengero cha threaded heads. Iyenera kuwerengedwa molingana ndi M=H/ZS (M ndi chiwerengero chonse cha ma turns omwe chipangizo chamagetsi chiyenera kukwaniritsa, ndipo H ndi kutalika kwa Valve opening, S ndi pitch ya thread ya valve stem drive, Z ndi chiwerengero cha stem thread heads).

D. M'mimba mwake mwa tsinde

Pa ma valve ozungulira okhala ndi ma turn ambiri, ngati mtunda wa tsinde wololedwa ndi actuator yamagetsi sungadutse mu tsinde la valavu yokonzedwa, sungasonkhanitsidwe mu valavu yamagetsi. Chifukwa chake, mtunda wamkati wa shaft yotulutsa yopanda kanthu ya chipangizo chamagetsi uyenera kukhala waukulu kuposa mtunda wakunja wa tsinde la valavu yozungulira. Pa ma valve ozungulira mbali ndi ma valve amdima m'ma valve ozungulira mbali zambiri, ngakhale kuti palibe chifukwa choganizira za kudutsa kwa tsinde la valavu, mtunda wa tsinde la valavu ndi kukula kwa keyway ziyeneranso kuganiziridwa mokwanira posankha, kuti valavu izigwira ntchito bwino mutasonkhanitsa.

E. Liwiro lotulutsa

Ngati liwiro lotsegula ndi kutseka la valavu ya gulugufe ndi lothamanga kwambiri, n'zosavuta kupanga nyundo yamadzi. Chifukwa chake, liwiro lotsegula ndi kutseka loyenera liyenera kusankhidwa malinga ndi momwe zinthu zimagwiritsidwira ntchito.
