J41H J41Y J41W 手動截止閥

沈陽鄭州高壓閥門手動、電動截止閥

一、手動截止閥J41H J41Y J41W主要特點及用途

主要特點及用途

structural features and purpose

1、結(jié)構(gòu)設(shè)計合理，剛性好，密封性能好.
2、在啟閉過程中.閥瓣與閥座密封間幾乎無磨擦，因而耐磨。
3、開啟高度小即可達(dá)到流量。
4、可安裝在管道的任意位置。
5、填料采用柔性石墨，啟閉靈活.密封可靠。
6、大口徑手動閥門配置撞擊手輪.
7、廣泛應(yīng)用于石油、化工、火力發(fā)電等水、燕汽、油品管路上作接通和截斷介質(zhì)。改變閥瓣形狀可用于系統(tǒng)介質(zhì)的節(jié)流。

1.Reasonable stnrctural design, good rigidity and goodsealmg performance.
2. In the course of open and close, nearly no abrasion is between the valve flap and valve suit. So, it is wearable.
3. Small open height can reality the flux.
4. Can be installed in any position of pipeline.
5. The filling adopts soft graphite, which can reach flexible open and dose and reliable sealing.
6. Large diameter manual valve is equipped with bump hand wheel.
7. Be widely cscd in the pipeline of water, vapor and oil prodtcts of petroleum, chemical indistry, thermal power for connection and dam media. To change the valve flap shape can throttle for systematic media.
