手動、電動截止閥

主要特點及用途

structural features and purpose

1、結構設計合理，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、廣泛應用於石油、化工、火力發電等水、燕汽、油品管路上作接通和截斷介質。改變閥瓣形狀可用於系統介質的節流。

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.

	使用中易出現的問題
	1、由於關閉過載及溫差影響而使閥門打不開. 2、由於介質所帶固體顆粒夾於密封麵，損壞密封麵而泄漏。
	Easy happening problem during the use
	1.The vale carrot be opened beats of ovedcad close and temperature difference. 2.The media with solid particle deposit at the bottom of coelom leads to uncompleted close of flashboard.
