主要特点及用途

structural features and purpose

1、结构设计合理，刚性好，密封性能好.
2、在启闭过程中.阀瓣与阀座密封间几乎无磨擦，因而耐磨。
3、开启高度小即可达到流量。
4、可安装在管道的任意位置。
5、填料采用柔性石墨，启闭灵活.密封可靠。
6、大口径手动阀门配置撞击手轮.
7、广泛应用于石油、化工、火力发电等水、燕汽、油品管路上作接通和截断介质。改变阀瓣形状可用于系统介质的节流。

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.

	使用中易出现的问题
	1、由于关闭过载及温差影响而使阀门打不开. 2、由于介质所带固体颗粒夹于密封面，损坏密封面而泄漏。
	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.
