Hydraulic balance valve Excavator hydraulic cylinder valve core PVDB-LWN

Kushanda musimboti weakananga kuita vharafu yekuyamura

1. Kudzvinyirira kuenzanisa: muviri wevhavha yevheji yekuyamura yakananga inogadziriswa nekiti yekuisa chisimbiso. Kana kudzvinyirirwa kunodarika kukosha kwegadziriro, chisimbiso chekuvhara chichabudisa simba, kusundira spool uye tsvimbo yekumanikidza kune imwe nzira;
2. Nheyo yekufambisa: Kana kudzvinyirira kwakakwirira kudarika kukosha kwegadziriro, tsvimbo yekumanikidza ichapfuura nemuviri wevhavha, kuitira kuti spool inosundirwa yakazaruka, uye chikamu chemafuta e hydraulic chinobudiswa kubva pachiteshi chekufashukira;
3. Kudzora nheyo: Kana kudzvinyirira kwakaderera kudarika kukosha kwegadziriro, tsvimbo yekumanikidzika ichadhonzwa nepiston uye inodzokera kudzoka munguva, kuitira kuti nheyo yevhavha idzoke zvakare, kuitira kuti udzivise hydraulic oiri inoyerera ichibva pachiteshi chekufashukira uye iyo system disconnection kugona;

Hunhu hwekunangisa kuita vharafu yekuyamura
1. Kukurumidza kupindura: iyo yakananga-inogadzirisa valve yekuyamura inotora nheyo yekumanikidzika kwekuenzanisa, iyo inogona kukurumidza kupindura kuchinja kwechiitiko;
2. Yakachengeteka uye yakavimbika: iyo yakananga-inogadzirisa valve yekuyamura inogonawo kushanda yakadzikama mukati mekumanikidzwa kukuru, iyo inogona kunyatsodzivirira kuchengetedzwa kwegadziriro;
3. Kuchengetedza kwakareruka: zvakananga kuita vharafu yekuyamura inongoda kuongororwa nguva dzose, hapana kuchinjwa nguva dzose kwezvikamu kunodiwa, uye kugadzirisa kunenge kuri nyore;
4. Mutsindo wakaderera: Direct acting relief valve inotora pressure balance control musimboti, kudzora nzira yekuvhara yakawedzera kupfava, inogona kuderedza ruzha, yakakodzera kune yakakwirira ruzha nharaunda.
