1. Disiki rerubber lined check valveiri disk-shaped uye inotenderera ichitenderera shaft inotenderera yevharuvhu yechigaro chevhavha. Nemhaka yokuti mugero uri muvharuvhu wakagadziridzwa, kuyerera kwemvura kuduku pane kuya kwevhavhavha yerudzi rwe butterfly. Butterfly cheki valve yakakamurwa kuva imwechete disc mhando, kaviri dhisiki mhando uye hafu yerudzi rwechitatu, aya mafomu matatu anonyanya kukamurwa zvichienderana nedhayamita yevharuvhu, chinangwa ndechekudzivirira yepakati kubva pakumisa kuyerera kana kudzoka shure, kuderedza iyo hydraulic impact.
2, Rubber lined check valve: valve disc inotsvedza ichitevedza mutsara wepakati wevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharwe,ruzha cheki chekivhavha inogona kungoiswa pahorizontal pombi,mukudzvanya diki caliber check valve disc inogona kushandiswa bhora. Chimiro chemuviri wevhavhavha yekutarisa inonyarara yakafanana neiyo yevharuvhu yepasirose (inogona kuve yepasi rose neglobe valve), saka iyo fluid inodzivirira coefficient yakakura. Chimiro chayo chakafanana nevhavha yepasi, uye muviri uye disc zvakafanana nevhavha yeglobhu. Chikamu chepamusoro che diski uye chikamu chezasi chechivharo chevhavha chinogadziriswa negwaro rekufambisa, uye dhidhiyo ye disc inogona kusimudzwa uye kuderedzwa zvakasununguka muvhavhavhavha yevhavha. Kana iyo svikiro ichiyerera, dhisiki inovhurwa nepakati nekukandira, uye kana iyo yepakati inomira kuyerera, iyo valve disc inogara pachigaro nedivi rakadzika kudzivirira yepakati kubva kune countercurrent. Yakatwasuka-kuburikidza neshavishavi cheki vharafu yepakati pekupinza uye yekubuda mugero nzira uye chigaro chiteshi chinotungamira perpendicular; Vertical lift cheki vharafu, iyo yepakati inlet uye yekubuda chiteshi nzira uye chigaro chiteshi gwara rakafanana, kuyerera kwekupokana kudiki pane yakatwasuka.
3. Rubber lined check valve: valve disc inotsvedza nepakati pemutsara wemuviri wevhavha.Pipe mhando cheki vharafuivharuvhu nyowani, saizi yayo diki, uremu huremu, yakanaka yekugadzirisa tekinoroji, ndeimwe yenzira yekuvandudza yevhavhavhavha. Asi iyo fluid yekudhonza coefficient yakakura zvishoma pane iyo ye swing cheki mavharuvhu.
