详细介绍

主要特点及用途

chief features and usages

1、产品结构设计合理，刚性好，流体阻力小。
2、密封面采用不锈钢和硬质合金，使用寿命长。
3、填料采用柔性石墨，启闭灵活，密封可靠。
4、闸板结构分弹性和刚牲两种形式。弹性闸板结构适应温差大的场合。
5、广泛适用于石油、化工、火力发电等水、蒸汽、油品管路上作接通和截断介质，不可作节流用。

1、compact structure easonable design good rigidity,smooth charnel small coefficient of flow resistance.
2、The sealing face uses stainless steel and car-bide alloy and is of long duration.
3、Using flexible graphite fillings. reliable sealing light and nimble opearation.
4、 Structure type elastic wedge type with single or dual-gate board
5、widely used as the clevice of open or close to connect of cat off the medium inside of the pipeline of water,steam or oil goods in steam power plants.

!!!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沉积体腔底部.导致闸板关闭不到位. 3、密封泄漏多由于密封面擦伤所致。
Easy happening problem during the use
1 .The valve cannot be opened be-cause of overload close and temperature difference. 2. The media with solid particle deposit at the bottom of coelom leads to uncom-pleted close of flashboard. 3. More sealing leakage arising fromscratch of sealing surface.
