Isibonelo, uma ufuna ukuvula i-DN100, i-valve butterfly ye-PN10, inani le-torque lingu-35NM, futhi ubude besibambo buyi-20cm (0.2m), khona-ke amandla adingekayo ngu-170N, okulingana no-17kg.
I-valve ye-butterfly iyi-valve engavulwa futhi ivalwe ngokuphendula ipuleti le-valve libe ngu-1/4 ukuphenduka, futhi inani lokujika isibambo libuye libe ngu-1/4.Khona-ke isikhathi esidingekayo sokuvula noma ukuvala sinqunywa i-torque.I-torque enkulu, i-valve ivula futhi ivale kancane.ngendlela efanayo.
2. I-Worm igiya le-butterfly valve:
ifakwe kuma-butterfly valves ane-DN≥50.Umqondo othinta inani lokujika nesivinini se-worm gear butterfly valve ubizwa ngokuthi "isilinganiso sejubane".
Isilinganiso sesivinini sisho isilinganiso esiphakathi kokuzungezisa kwe-actuator shaft (isondo lesandla) nokuzungezisa kwepuleti levalvu uvemvane.Isibonelo, isilinganiso sesivinini se-DN100 turbine butterfly valve ngu-24:1, okusho ukuthi isondo lesandla ebhokisini le-turbine lizungeza izikhathi ezingu-24 bese ipuleti levemvane lizungezisa indilinga engu-1 (360°).Nokho, i-angle enkulu yokuvula ipuleti levemvane ngu-90°, okuyindilinga engu-1/4.Ngakho-ke, isondo lesandla ebhokisini le-turbine lidinga ukushintshwa izikhathi ezingu-6.Ngamanye amazwi, u-24:1 usho ukuthi udinga kuphela ukujika isondo le-turbine butterfly valve 6 ukuze uqedele ukuvuleka noma ukuvala ivalve yovemvane.
| DN | 50-150 | 200-250 | 300-350 | 400-450 |
| Yehlisa Isilinganiso | 24:1 | 30:1 | 50:1 | 80:1 |
"Onesibindi" ifilimu ethandwa kakhulu futhi ethinta inhliziyo ngo-2023. Kunemininingwane yokuthi izicishamlilo zangena phakathi nendawo yomlilo futhi zajika mathupha ukuphenduka kwe-8,000 ukuvala i-valve.Abantu abangayazi imininingwane bangase bathi "lokhu kuyihaba kakhulu."Eqinisweni, isicishamlilo saphefumulela indaba ethi "Onesibindi" endabeni " yaphenduka i-valve 80,000, amahora angu-6 ngaphambi kokuyivala.
Ungathuswa yileyo nombolo, efilimini i-valve yesango, kodwa namuhla sikhuluma nge-valve butterfly.Inani lama-revolutions adingekayo ukuvala i-valve uvemvane ye-DN efanayo akudingekile ukuba libe liningi kangako.
Ngamafuphi, inani lokuvula nokuvala ukujika kanye nesikhathi sesenzo se-valve uvemvane kuncike ezintweni eziningi, njengohlobo lwe-actuator, izinga lokugeleza okuphakathi nokucindezela, njll., futhi kudingeka kukhethwe futhi kulungiswe ngokuya ngesimo sangempela. .
Ngaphambi kokuxoxa ngenani lokujika elidingekayo ukuvala i-valve uvemvane, ake siqale siqonde ithuluzi elidingekayo ukuze uvule i-valve uvemvane: i-actuator.Ama-actuator ahlukene anezinombolo ezihlukene zokujika ezisetshenziselwa ukuvala i-valve uvemvane, futhi isikhathi esidingekayo sihlukile.
Ifomula yokubala ye-Butterfly valve yokuvula nokuvala isikhathi Isikhathi sokuvula nesokuvala se-valve uvemvane sibhekisela esikhathini esisithathayo ukuze i-valve uvemvane iqede isuke ivuleke ngokugcwele iye ivaleke ngokugcwele noma isuke ivaleke ngokugcwele iye ivuleke ngokugcwele.Isikhathi sokuvula nokuvala se-valve ye-butterfly sihlobene nesivinini sesenzo se-actuator, ukucindezela kwamanzi nezinye izici.
t=(90/ω)*60,
Phakathi kwazo, t isikhathi sokuvula nokuvala, i-90 i-angle yokujikeleza ye-valve butterfly, futhi ω yi-angular velocity ye-valve butterfly.
1. Bamba i-valve uvemvane olusebenzayo:
Ngokuvamile kufakwe ama-valve evemvane ane-DN ≤ 200 (usayizi omkhulu ungaba ngu-DN 300).Kuleli qophelo, kufanele sikhulume umqondo obizwa ngokuthi "torque".
I-torque isho inani lamandla adingekayo ukuze uvule noma uvale i-valve.Le torque ithintwa yizici ezihlukahlukene, okuhlanganisa ubukhulu be-valve uvemvane, ingcindezi nezici zemidiya, nokungqubuzana ngaphakathi komhlangano we-valve.Amanani etorque ngokuvamile avezwa ngamamitha e-Newton (Nm).

3. Ivalve uvemvane ecushwe ngogesi:
Ifakwe i-DN50-DN3000.Uhlobo olufanele ama-valve ovemvane luyidivayisi kagesi yekota (i-engeli ejikelezayo engu-360 degrees).Ipharamitha ebalulekile i-torque, futhi iyunithi ingu-Nm
Isikhathi sokuvala se-valve uvemvane kagesi siyalungiseka, kuye ngamandla, umthwalo, isivinini, njll. se-actuator, futhi ngokuvamile asikho ngaphezu kwamasekhondi angu-30.
Ngakho-ke kuthatha amajika amangaki ukuvala ivalve uvemvane?Isikhathi sokuvula nokuvala se-valve uvemvane sincike ejubaneni lemoto.Isivinini sokuphuma kwe-Ivalvu yeZFAokwejwayelekile okokusebenza kukagesi ngu-12/18/24/30/36/42/48/60 (R/min).
Isibonelo, uma ikhanda likagesi elinejubane lokujikeleza lika-18, kanye nesikhathi sokuvala samasekhondi angu-20, inani lokujika elivalayo liyi-6.

Isikhumbuzi esifudumele: Iswishi kagesi yevalvu idinga itorque ukuze isebenze kukho.Uma i-torque incane, ingase ingakwazi ukuvula noma ukuvala, ngakho-ke kungcono ukukhetha enkulu kunencane.
