Balance valve pilot yakashanda vharafu yekuyamura CBBG-LJN

Iyo yetatu-port cartridge balancing valve ivharuvhu inogadziriswa (pilot mafuta-inobatsirwa kuvhura). Inobvumira kuyerera kwemahara kwemafuta kubva pachiteshi 2 (inlet) kuenda kuchiteshi 1 (chiteshi chekutakura): kuyerera kwemafuta kunomiswa.
Fambisa (muromo 1 kuenda kumuromo 2) kusvika dzvinyiriro yemutyairi, iyo inopesana nekuremerwa kwemutoro, inobata pamuromo 3 isati yavhura. Kugadziriswa kwechiteshi chevhavhavhavhavha ndiyo mhedzisiro yekuita kaviri kwekumanikidza kwemutoro uye kudzvanywa kwemutyairi, iyo inoumba "inverse pilot pressure ratio": mwenje wakareruka unoda kuti kuvhurwa kwemutyairi wekuvhura kuve kwakakura kupfuura mutoro, kuvandudza kugadzikana. uye zviri nani kufamba kwekutonga.
Basa rekugadzirisa kufamba kwevhavhavha yebhavhari rinoratidzwa mukuchengetedza hutano hwakanaka hwekuremerwa pavhavha inodzosera kunyange kana mutoro unopfuura. Kana vharafu yakavharwa, kubuda kwayo kudiki kwazvo (pedyo ne zero). Smooth unnotched zvigaro uye marara akatsetseka mumafuta (kunyangwe akanyanya "akachena" mafuta) anoumba chisimbiso mukati memaminitsi evhavhavhavha inovhara kuti ibvise kubuda. Iyo inosimba yekudzikisa mutoro wekudzora inogona kuitika nekusarudza yakakodzera kudzosera valve uye dhizaini dhizaini. Panguva imwecheteyo, basa rekufashukira rechiteshi 1 (chiteshi chekutakura) kuenda kuchiteshi 2 (inlet) chinosanganiswa kudzivirira kuwandisa uye kupisa kwemutoro. Ivhavha yevhavha yevhavha mitatu ine countercurrent check valve inokodzera kushanda pasi pemutoro unoramba uripo, iyo iyo mhepo yevhavha inofanira kuiswa pa 1.3 nguva inoramba iine mutoro (port 3 pressure haina kuverengwa). Balanced cartridge valve performance yakaita seiyi:
Iyo leakage idiki pa cutoff. Pamutengo wakatarwa we85%, iyo yekudonha yakanyanya kudonha ndeye 5 madonhwe / min (0.4cc/min).
Iyo hysteresis yevhavha yekuyamura zvakare idiki kana chiyero chekuyerera chichichinja zvakanyanya.
Kuramba kwakasimba kusvibiswa kwemafuta. Kushanda kumanikidza kusvika ku5000psi (350bar). Kuyerera kwe120gpm(460L/min)
Inogadziriswa screws inogona kushandiswa kudzikisa kudzvanywa kweseti: kana mutyairi wemutyairi asina kukwana, iyo emergency manual kuburitsa screw inogona kushandiswa.
