Isibonelo, uma ufuna ukuvula ivalvu yebhabhathane i-DN100, PN10, inani le-torque lingu-35NM, kanti ubude besibambo bungu-20cm (0.2m), khona-ke amandla adingekayo angu-170N, okulingana no-17kg.
Ivalvu yebhabhathane iyivalvu engavulwa futhi ivalwe ngokuphendula ipuleti levalvu ngokujika okungu-1/4, kanti inani lokujika kwesibambo nalo liyijika elingu-1/4. Bese isikhathi esidingekayo sokuvula noma ukuvala sinqunywa yi-torque. Uma i-torque inkulu, ivalvu ivula futhi ivala kancane. Ngokuphambene nalokho.
2. I-valve yebhabhathane eqhutshwa yigiya le-worm:
ifakwe kuma-valve e-butterfly ane-DN≥50. Umqondo othinta inani lokujika kanye nesivinini se-worm gear butterfly valve ubizwa ngokuthi "isilinganiso sesivinini".
Isilinganiso sejubane sibhekisela kusilinganiso esiphakathi kokujikeleza kwe-actuator output shaft (isondo lesandla) kanye nokujikeleza kwepuleti le-butterfly valve. Isibonelo, isilinganiso sejubane se-DN100 turbine butterfly valve singu-24:1, okusho ukuthi isondo lesandla ebhokisini le-turbine lijikeleza izikhathi ezingu-24 kanti ipuleti le-butterfly lijikeleza indilinga engu-1 (360°). Kodwa-ke, i-engeli yokuvula ephezulu yepuleti le-butterfly ingu-90°, okuyindilinga engu-1/4. Ngakho-ke, isondo lesandla ebhokisini le-turbine lidinga ukuphendulwa izikhathi ezingu-6. Ngamanye amazwi, u-24:1 usho ukuthi udinga kuphela ukujika isondo lesandla le-turbine butterfly valve izikhathi ezingu-6 ukuze uqedele ukuvulwa noma ukuvalwa kwe-butterfly valve.

I-“The Bravest” yifilimu ethandwa kakhulu futhi ethinta inhliziyo ngo-2023. Kukhona imininingwane yokuthi abacishi bomlilo bangene phakathi komlilo futhi bajika ngesandla amajika angu-8,000 ukuze bavale ivalvu. Abantu abangayazi imininingwane bangase bathi “lokhu kuyihaba kakhulu.” Eqinisweni, umcimi womlilo uphefumulele indaba ethi “The Bravest” endabeni “wajika ivalvu amajika angu-80,000, amahora ayisithupha ngaphambi kokuba ayivale.
Ungamangali yilelo nani, ku-movie liyivalvu yesango, kodwa namuhla sikhuluma ngevalvu yebhabhathane. Inani lokujikeleza okudingekayo ukuvala ivalvu yebhabhathane ye-DN efanayo akudingeki neze libe liningi kangako.
Ngamafuphi, inani lokujika nokuvula kanye nesikhathi sokusebenza kwevalvu yevemvane kuncike ezintweni eziningi, njengohlobo lwe-actuator, izinga lokugeleza eliphakathi kanye nengcindezi, njll., futhi kudinga ukukhethwa nokulungiswa ngokwesimo sangempela.
Ngaphambi kokuxoxa ngenani lamajika adingekayo ukuvala ivalvu yebhabhathane, ake siqale siqonde ithuluzi elidingekayo ukuvula ivalvu yebhabhathane: i-actuator. Ama-actuator ahlukene anezinombolo ezahlukene zamajika asetshenziswa ukuvala ivalvu yebhabhathane, futhi isikhathi esidingekayo naso sihlukile.
Ifomula yokubala isikhathi sokuvula nokuvala ivalvu yebhabhathane Isikhathi sokuvula nokuvala ivalvu yebhabhathane sibhekisela esikhathini esithathayo ukuthi ivalvu yebhabhathane iqede kusukela ekuvulekeni ngokuphelele kuye ekuvalekeni ngokuphelele noma kusukela ekuvalekeni ngokuphelele kuye ekuvulekeni ngokuphelele. Isikhathi sokuvula nokuvala ivalvu yebhabhathane sihlobene nesivinini sokusebenza kwe-actuator, umfutho woketshezi nezinye izici.
t=(90/ω)*60,
Phakathi kwazo, u-t yisikhathi sokuvula nokuvala, u-90 uyi-engeli yokujikeleza kwevalvu yevemvane, kanti u-ω uyijubane le-angular levalvu yevevu yevevu.
1. Ivalvu yebhabhathane esetshenziswa yisibambo:
Ngokuvamile ifakwe kuma-valve e-butterfly ane-DN ≤ 200 (usayizi omkhulu ungaba yi-DN 300). Kuleli qophelo, kufanele sikhulume ngomqondo obizwa ngokuthi "i-torque".
I-torque ibhekisela enanini lamandla adingekayo ukuvula noma ukuvala i-valve. Le torque ithintwa yizici ezahlukahlukene, okuhlanganisa ubukhulu be-valve ye-butterfly, ingcindezi kanye nezici ze-media, kanye nokungqubuzana ngaphakathi kwe-valve assembly. Amanani e-torque avame ukuvezwa ngamamitha e-Newton (Nm).

3. Ivalvu yebhabhathane esebenza ngogesi:
Ifakwe i-DN50-DN3000. Uhlobo olufanele ama-valve e-butterfly idivayisi kagesi ejika ngekota (i-engeli ejikelezayo engu-360 degrees). Ipharamitha ebalulekile i-torque, kanti iyunithi yi-Nm
Isikhathi sokuvala sevalvu yebhabhathane kagesi siyalungiseka, kuye ngamandla, umthwalo, isivinini, njll. se-actuator, futhi ngokuvamile asidluli imizuzwana engama-30.
Ngakho-ke kuthatha ukujika okungaki ukuvala ivalvu yebhabhathane? Isikhathi sokuvula nokuvala ivalvu yebhabhathane sincike esivinini senjini. Isivinini sokuphuma kwevalvuI-valve ye-ZFAkwemishini kagesi evamile ingu-12/18/24/30/36/42/48/60 (R/min).
Isibonelo, uma ikhanda likagesi linejubane lokujikeleza elingu-18, kanye nesikhathi sokuvala esingu-20 imizuzwana, khona-ke inani lamajika elivalayo lingu-6.

Isikhumbuzo Esifudumele: Iswishi kagesi yevalvu idinga i-torque ukuze isebenze kuyo. Uma i-torque incane, ingase ingakwazi ukuvula noma ukuvala, ngakho-ke kungcono ukukhetha enkulu kunencane.
