PBQ940H 电动偏心半球阀

    电动偏心半球阀是在吸收消化国外的*技术而研发成功的新产品,也是*国内阀门品种空白的创新产品,是在认真权衡球阀、蝶阀、闸阀等多种阀门优缺点的前提下,借鉴德国类似产品而开发的全部国产化创新产品,应用于石油、化工、电力和冶金等行业,其核心技术属国内*,它设计*、结构新颖。产品投放市场以来，受到顾客的首肯。

*：阀门结构采用偏心契紧原理，通过传动机构达到闸紧、调节、关闭的目的，密封圈与球体都是金属面环带硬面接触密封，双偏心结构阀门在开启是球体藏于阀腔内，流通载面大，且阀门不被冲刷，无流阻。关闭时阀芯不被冲刷，关闭时阀芯球面沿阀座渐进，具有剪切功能，有效得切除结垢障碍，实现可靠密封。它对容易结垢的介质输送特别有效。

第二：阀门与半球采用双金属，在球体上堆焊不用的合金，阀座也作相应堆焊合金，经特殊的处理，密封面组合成防腐、耐磨、耐高温等各种类型，满足不同场合需求。

第三：密封严紧，输送有害气体可达到零泄露。

第四：阀座与球体保留有补偿量，当阀座磨损后，关闭时再转动少许，仍能可靠密封，延长使用寿命，此外，用户将一压板螺栓拧掉，从新调整或更换后阀座仍可用，避免了众多阀门密封失效整台报废的弊端。

根据用户需要堆焊不同的合金，双金属密封圈的选配可以用于耐磨、耐腐蚀、耐高温等而又要求严格密封的不同工业部门。

电动偏心半球阀产品的主要用途及产品特点

1、通用阀：适用于污水处理、纸浆、氧化铝、城市采暖供热要求严紧的场合。

2、油化工阀：适用于原油，重油等各类油品、化工行业耐腐蚀、两相混流介质。耐温可达425℃。

3、燃气阀：适用于煤气、天然气、液化气的输送控制。产品结构特点是在密封圈堆焊阀不同含铬合金，密封严紧、抗腐蚀。

4、料浆阀：适用于液态、固态两相混流或液态输送化学反应有结晶析分或结垢的工业管道输送。产品结构特点根据顾客所需介质、温度要求不同，球体受用铬钼、钒合金堆焊，阀座采用铬、钼合金、铬合金、不锈钢合金焊条堆焊满足不同料浆输送的需要。

5、煤粉灰渣阀：适用于电厂、水力除渣或气态输送管道的控制。产品要求耐磨性能，球体采用组合球式双金属，具有相当高的刚度并非常耐磨。阀座采用整体耐磨钢或全堆焊。
