Injiniya yemigodhi yemichina zvikamu Hydraulic valve cartridge balancing valve RPGE-LCN

Hydraulic valve inhengo ye otomatiki inoshandiswa nemafuta ekumanikidza, inodzorwa nepressure valve pressure oil, inowanzosanganiswa neelectromagnetic pressure valve, inogona kushandiswa kuremotedza hydropower station mafuta, gasi, mvura pombi system. Inowanzo shandiswa kusungirira, kutonga, lubrication uye mamwe mafuta edunhu. Kune yakananga chiito mhando uye piyona mhando, akawanda-kushandisa mapiyona mhando. Basa re hydraulic valve rinonyanya kushandiswa kudzikisa uye kudzikamisa kudzvanywa kwemafuta ebazi muhurongwa, uye inowanzoshandiswa kusungirira, kutonga, kuzora uye mamwe maseketi emafuta. Kune yakananga inofamba mhando, inotungamira mhando uye superposition mhando. Chinhu chinoshandiswa mukufambiswa kwehydraulic kudzora kudzvanywa, kuyerera, uye nzira yezvinwiwa. The pressure control valve inonzi pressure control valve, flow control valve inonzi flow control valve, and control on, off and flow direction inonzi direction control valve. Kurongeka kwemavharuvhu e hydraulic: kupatsanurwa nebasa: kuyerera kwevharuvhu (vhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha ku vhuya,kumisa vheji,diverter vharuvhu,kutsarukana,diverter kuunganidza vharuvhu), pressure valve (relief valve, pressure reduction valve, sequence valve, unloading valve) electromagnetic reversing valve, manual reversing valve, check valve, hydraulic control check valve)

Mavharuvhu ekuyamura ekutyaira anowanikwa mune zvakasiyana-siyana zvigadziriso. Iyo yakajairwa-chikamu chetatu-yakadzika dhizaini yekuyamura vharafu, iyo inoumbwa nezvikamu zviviri: pilot vharafu uye huru vharuvhu.

Iyo taper pilot vharafu, gomba rekunyorovesa (yakagadziriswa throttle hole) pahombe yevharuvhu uye kudzvanywa kunodzora chitubu pamwe chete zvinoumba mutyairi hafu-bhiriji chikamu chekumanikidza negative mhinduro yekutonga, iyo ine basa rekupa iyo huru nhanho yekumanikidza kumanikidza mushure mevharuvhu yekutyaira. kudzora kudzvinyirira kukamuri yepamusoro yevharuvhu huru spool. Iyo huru spool ndiyo muenzanisi weiyo huru control loop. Chiso chepamusoro chinoshanda sesimba rekuraira reiyo main spool, nepo kumucheto kwepasi kunoshanda sekumanikidza kuyera pamusoro peiyo huru loop uye kuita sesimba remhinduro. Simba rinoguma rinogona kutyaira spool, kugadzirisa saizi yechiteshi chekufashukira, uye pakupedzisira kuzadzisa chinangwa chekutonga nekugadzirisa kudzvanywa kweiyo inlet pressure P1.
