产品描述
一、偏心半球阀特点:
1、其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,密封副是金属面环带硬面接触密封,双偏心结构在开启时阀芯位于藏球室内,流通截面大,且阀门不被冲刷,关闭时阀芯不被冲刷,开启时阀芯球面沿阀座渐进,有效地切除结垢障碍,实现可靠密封。它对两相混流易结垢固体析出的混流输送特别有效
2、阀门的半球用双金属,母材上堆焊不同的合金,阀座也作相应堆焊经特殊的处理,密封面组合成防腐、耐磨、高强度等各种类型,满足不同场合需求
3、密封严密、输送有害气体可达零泄露
4、密封副的阀芯留有补偿量、当阀做磨损后,关闭时再转动少许,任能可靠密封,延长了使用寿命。此外,用户将压紧螺母拧掉,调整或更换后阀座仍可用,避免了阀门密封失效后,整台报废的弊端
