ZZYVP Pilot self-operated pressure regulator imatha kugwira ntchito popanda magetsi ndi mpweya.ZZYVP Pilot self-operated pressure regulator ndi mtundu wa valve yopulumutsa mphamvu yomwe imagwiritsa ntchito kusintha kwapakati pa kusintha kwa sing'anga kuti izindikire kusintha kwachangu komanso kufunikira kosalekeza kwa kukakamiza. pambuyo valavu.ZZYVP Woyendetsa wodziyendetsa yekha kukakamiza woyendetsa ntchito sing'anga: gasi wosawononga.
ZZYVP Pilot self-operated pressure regulator akhoza kuika chandamale kukakamiza wotsogolera pa ntchito, kotero ndi yabwino, mofulumira, ntchito yopulumutsa ndi kupulumutsa nthawi. (mwachitsanzo 50mm madzi mgawo kuthamanga), decompression chiŵerengero ndi mkulu, pazipita decompression chiŵerengero ndi 100: 1 pamene kuthamanga pamaso valavu ndi pansi 8bar.
ZZYVP Pilot self-operated pressure regulator ndi kawiri kuposa ZZY self-operated valve valve, makamaka yomwe ikugwiritsidwa ntchito pa nthawi yowonongeka kwa mpweya, pamene kupanikizika patsogolo pa valve ndi 1 ~ 8bar ndipo kupanikizika pambuyo pa valve kuli pansi pa 15KPa.

Pilot self-operated pressure regulator structure
Pilot self-operated pressure regulator ntchito mfundo
1.Pachiyambi, spool yaikulu ya valve ya ZZYVP Pilot self-operated pressure regulator imakhala yotsekedwa pansi pa spring11 action force.Director 08 amakhala otseguka pansi pa Spring 17 Action Force.
2. Sing'anga imalowa mu valavu yowongolera pansi pa njira ya muvi, kupyolera mu valve yothandizira 06, yopita kwa wotsogolera 08, kupyolera mu director 08 ndi throttle valve 13, kutuluka kwa actuator 07 chipinda cha diaphragm pansipa.Kupsyinjika kochokera ku chipinda cha diaphragm cha actuator07 pansipa chikukwera.Vavu yaikulu idzatsegulidwa pansi pa kupanikizika.Sing'anga imayenderera mu valavu, kudzera papampopi ya 09 ndi 21, kenaka imalowa mu chipinda cha diaphragm cha actuator07 pamwamba ndi chipinda cha diaphragm chowongolera 08 pamwamba.
3.Pamene kupanikizika kwa P2 pambuyo poti valve ikukwera, kupanikizika kwa P4 kumagwira ntchito pa chipinda cha 07 cha diaphragm pamwamba chikukwera, digiri yoyamba yotsegulira valve ikucheperachepera ndipo kupanikizika pambuyo pa valve kumachepetsa (kusintha koyambirira).Pakadali pano, kukakamizidwa kwa P6 kuchipinda cha director 08 diaphragm pamwambapa kukukwera ndipo digiri yotsegulira ya director 08 ikuchepera.Kupsyinjika kwa P5 mu chipinda cha diaphragm cha actuator 07 pansipa kukuchepa.ZZYVP Pilot yodziyendetsa yokha yamagetsi owongolera digirii yayikulu yotsegulira ikucheperachepera ndipo kupanikizika pambuyo pa valavu kumachepera (kusintha bwino).
4.Pamene kupanikizika kwa P2 pambuyo pa valavu kumachepetsa, kupanikizika kwa P4 kumagwira ntchito pa chipinda cha 07 cha diaphragm pamwamba ndikuchepetsa.Digiri yaikulu yotsegulira valve ikuwonjezeka, ndipo kupanikizika pambuyo pa valve ikukwera (kusintha koyambirira).Pakadali pano, kupanikizika kwa P6 mu chipinda cha 08 cha diaphragm pamwamba kukucheperachepera, Digiri 08 yotsegulira ikuwonjezeka, ndipo kukakamiza P5 kulowa m'chipinda cha 07 diaphragm pansi kukukwera.Digiri yotsegulira valavu yayikulu ikuchulukirachulukira ndipo kupanikizika pambuyo pa valavu kumapitilirabe (kusintha kwabwino).
5.The spool yaikulu ya valve ya ZZYVP Pilot self-operated pressure regulator ndi director 08 sichidzasiya kugwira ntchito mpaka itafika pamtengo wokhazikika.Panthawiyi, kupanikizika pambuyo pa valavu kukhazikitsidwa mtengo, decompression yamphamvu imatha kuchitika.
