ZZYVP Pilot self-operated pressure regulator inogona kushanda pasina magetsi nemhepo.ZZYVP Pilot self-operated pressure regulator imhando yesimba rekuchengetedza simba rekudzora vharafu rinoshandisa kuzvidzora shanduko yepakati yakagadziridzwa kuti uone kugadziridzwa otomatiki uye kukosha kwenguva dzose kwekumanikidza. mushure mevharuvhu.ZZYVP Pilot self-operated pressure regulator inoshanda medium: non-corrosive gas.
ZZYVP Pilot self-operated pressure regulator inogona kuseta kudzvanywa kwechinangwa pane mutungamiriri panguva yekushanda, saka zviri nyore, nekukurumidza, kuchengetedza vashandi uye kuchengetedza nguva. (eg50mm mvura column pressure), decompression reshiyo yakakwira, yakanyanya decompression reshiyo i100:1apo pressure pamberi pevharuvhu iri pazasi 8bar.
ZZYVP Pilot self-operated pressure regulator inopeta zvakapetwa kaviri seZZY self-operated control valve, inonyanyoshanda pachiitiko chegasi decompression, uko kudzvanywa pamberi pevharuvhu iri 1 ~ 8bar uye kumanikidza mushure mevharuvhu iri pazasi 15KPa.

Pilot self-operated pressure regulator chimiro kudhirowa
Pilot self-operated pressure regulator inoshanda musimboti
1.Pakutanga, main valve spool yeZZYVP Pilot self-operated pressure regulator inoramba yakavharwa pasi pe spring11 action force.Director 08 inoramba yakavhurika pasi pechirimo 17 chiito simba.
2. Iyo yepakati inoyerera ichipinda muvharuvhu yekudzora pasi pegwara remuseve, kuburikidza nevharuvhu yekuyamura 06, ichiyerera ichienda kumutungamiriri 08, kuburikidza nemutungamiriri 08 uye throttle valve 13, inoyerera kune actuator 07 diaphragm chamber pazasi.Dzvinyiriro kubva kuactuator07 diaphragm kamuri pazasi iri kukwira.Ivhavha huru ichazarura pasi pekumanikidzwa.Iyo yepakati inoyerera ichipinda muvharuvhu, kuburikidza nekumanikidza tap 09 uye 21, yobva yayerera ichipinda muactuator07 diaphragm chamber kumusoro uye director 08 diaphragm chamber kumusoro.
3.Apo kudzvinyirirwa kweP2 mushure mekuvhara kwevhavha kuri kukwira, simba reP4 rinoshanda pane actuator 07 diaphragm chamber iri pamusoro iri kukwira, dhigirii huru yekuvhura valve iri kuderedza uye kudzvinyirira mushure mokunge valve iri kuderedza (kugadzirisa kwekutanga).Zvichakadaro, dzvinyiriro P6 ichiita pane director 08 diaphragm kamuri iri pamusoro iri kusimuka uye director 08 yekuvhura degree iri kudzikira.Dzvinyiriro P5 muactuator 07 diaphragm kamuri pazasi iri kudzikira.Iyo ZZYVP Pilot inozviitira-inoshanda kudzvanya regulator hombe yekuvhura dhigirii iri kudzikira uye kudzvanywa mushure mevharuvhu inoramba ichidzikira (kugadziriswa kwakanaka).
4.Apo kudzvinyirirwa kweP2 mushure mekuvhara kwevhavha iri kuderera, kumanikidzwa kweP4 kunobata pane actuator 07 diaphragm chamber iri pamusoro iri kuderedza.Main valve kuvhura dhigirii iri kuwedzera, uye kudzvinyirira mushure mokunge valve ichikwira (kugadzirisa kwekutanga).Zvichakadaro, dzvinyiriro yeP6 mukamuri 08 diaphragm iri pamusoro iri kudzikira, director 08 yekuvhura dhigirii iri kuwedzera, uye kudzvanywa P5 muactuator 07 diaphragm kamuri iri pazasi iri kusimuka.Iyo huru valve yekuvhura dhigirii iri kuramba ichiwedzera uye kudzvanywa mushure mevharuvhu kunoramba kuchiwedzera (kugadziriswa kwakanaka).
5.Iyo huru yevhavha spool yeZZYVP Pilot self-operated pressure regulator uye mutungamiriri 08 haizoregi kushanda kusvikira yasvika pamutengo wakatarwa.Panguva ino, dzvinyiriro mushure mevhavha yaiswa kukosha, dynamic decompression inogona kuitika.
