气动偏心半球阀产品概述

双偏心半球阀利用偏心阀体,偏心球体和阀座,阀杆作旋转运动时在共同轨迹自动定心,关闭过程中越关越紧,*达到良好的密封目的。阀门的球体和阀座*脱离,消除了密封圈的磨损,克服了传统球体阀座与球体密封面始终磨损的问题,非金属弹性材料被嵌入金属座中,阀座金属面受到良好的保护。本产品特别适用于钢铁业,铝业,纤维,微小固体颗粒,纸浆,煤灰,石油气等介质.

气动偏心半球阀产品特点

1、双偏心半球阀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   因堆焊不同合金(或组合球)双金属密封副的选配可以用于耐磨、耐腐蚀、耐高温且要求严格密封的工况 
1、通用阀:规格型号DN40-1600。适用于污水处理、纸浆、城市采暖供热等要求严紧的场合 
2、油化工阀:规格DN40-1600。适用于原油、重油等各类油品、化工行业弱腐蚀、二相混流介质 
3、煤气阀:规格DN40-1600。适用于煤气、天然气、液化气的输送控制 
4、料浆阀:规格DN40-1600。适用于液态、固态两相混流或液态输送中化学反应有结晶析出或结垢的工业管道输送 
5、煤粉灰渣阀:规格DN40-1600。适用于电厂、水力除渣或气态输送管道的控制     
 

执行标准

设计:GB12237-89 
法兰连接:GB/T17241.6-1998、GB/T9115(钢制)
结构长度:GB12221-89
