Gawoli likufotokoza zigawo zikuluzikulu ndi mfundo zogwirira ntchito za valavu yagulugufe yoyendetsedwa ndi hydraulic

Vavu yagulugufe ya hydraulic ndi valavu yomwe imagwiritsidwa ntchito kuwongolera kutuluka kwa media media. Zigawo zake zazikulu zimaphatikizapo thupi la valve, valavu disc, hydraulic control chamber, actuator ndi hydraulic control components. Zotsatirazi zikufotokozera zigawo zikuluzikulu za hydraulic butterfly valve ndi mfundo zake zogwirira ntchito.

Thupi la valve
Thupi la valve la gulugufe lomwe limayendetsedwa ndi madzi nthawi zambiri limapangidwa ndi chitsulo cha ductile kapena zitsulo zotayidwa, zomwe zimakhala ndi kutentha kwapamwamba kwambiri, kukana kwa dzimbiri, kukana kuvala komanso kukana kukakamizidwa. Mkati mwa thupi la valve umagwiritsidwa ntchito ndi chophimba chapadera kapena enamel kuti awonjezere kukana kwa dzimbiri.

Kuwala kwa valve
Chimbale cha hydraulic butterfly valve nthawi zambiri chimawotchedwa ndi zitsulo zotayidwa kapena mbale yachitsulo ndikudzazidwa ndi zinthu zosindikizira monga polytetrafluoroethylene kapena rabara. Mawonekedwe a diski ya valve nthawi zambiri amakhala mawonekedwe a disc, omwe amakhala ndi magwiridwe antchito abwino.

Madzi oyendetsedwa ndi madzi
Chipinda chowongolera ma hydraulic cha hydraulic control butterfly valve ndi gawo lofunikira la gawo la hydraulic control component, lomwe nthawi zambiri limapangidwa ndi zotanuka zomata. Mapeto apamwamba ndi apansi a chipinda chowongolera ma hydraulic amalumikizidwa motsatana ndi chitoliro cha hydraulic ndi chitoliro cha mpweya, ndipo amagwirizana ndi malo apamwamba ndi otsika a disc valve.

Executive mechanism
The actuator ya hydraulic butterfly valve nthawi zambiri amagwiritsa ntchito kuphatikiza kwa hydraulic unit ndi air pressure unit kuti azitha kuwongolera kusintha kwamphamvu muchipinda chowongolera ma hydraulic, kuti athe kuwongolera kutsegulidwa kwa valavu. Chigawo cha hydraulic chimayang'anira chigawo cha hydraulic control posintha kayendedwe ndi kupanikizika kwa mafuta oponderezedwa, pamene chigawo cha pneumatic chimayang'anira payipi yamagetsi mwa kusintha kayendedwe ka mpweya ndi kuthamanga kwa mpweya.

Hydraulic control element
Zida zowongolera ma hydraulic za hydraulic butterfly valve zimaphatikizapo valavu yayikulu yowongolera ndi valavu yowongolera kuthamanga. Chovala chachikulu chowongolera chimasintha kupanikizika mu chipinda chowongolera ma hydraulic mwa kuwongolera kuthamanga ndi kuthamanga kwa mafuta a hydraulic, kuti athe kuwongolera kutsegulidwa kwa diski ya valve. The kuthamanga ulamuliro valavu zimakhudza kuthamanga kusintha mu madzi ulamuliro chipinda ndi kulamulira kuthamanga mu mpweya kuthamanga payipi, motero zimakhudza kuthamanga kusintha mu madzi ulamuliro chipinda.

Mfundo yogwira ntchito ya hydraulic butterfly valve ndiyo kuyendetsa kutsegula kwa valavu pogwiritsa ntchito mphamvu ya hydraulic pressure ndi mpweya wa mpweya, kuti muzitha kuyendetsa kayendedwe kake. Pakafunika kuwongolera kusintha kwapakati, gawo la hydraulic limasintha kutsegulira kwa diski ya valve mwa kusintha kupanikizika mu chipinda chowongolera ma hydraulic. Chigawo chowongolera mpweya chimakhudza kusintha kwamphamvu m'chipinda chowongolera ma hydraulic mwa kusintha kupanikizika kwapaipi yapaipi ya mpweya, motero kusintha kutsegulidwa kwa disc valve.

Mwachidule, valavu ya butterfly ya hydraulic ndi njira yolamulira yochokera ku hydraulic ndi mpweya wa mpweya, ndipo kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Kuphatikizika kwa thupi la valve, valavu disc, hydraulic control chamber, actuator ndi hydraulic control element ndiye chinsinsi chokwaniritsa mphamvu ya hydraulic control butterfly valve.
