气动套筒调节阀 - 上海仪欣阀门有限公司

气动套筒调节阀

气动套筒调节阀适用控制流体介质流量、压力和高负荷工况。阀体结构紧凑,流体通道呈S流线型,允许流通能力大,可调范围广,流量特性精度高。阀芯导向部分的导向面积大,具有抗振性能强的特点。阀座密封性能符合IEC或者GB标准,调节阀配用多弹簧式薄膜执行机构,结构紧凑、输出力大。气动套筒调节阀广泛使用于要求可靠性和关闭性能高、低温以及高压工艺管线场合,由于材料范围广和设计形式的多样化,使得这些阀门可在不同的工业领域中得以应用(譬如:化工、电力、造纸、食品、冶金、采矿等)。

产品特点

1.阀座采用卡入式结构避免了螺纹旋入式的缺陷,当压紧上盖时阀芯和阀座自动对中,而且装卸简单方便,即使在严重腐蚀的情况下也能轻松的取出阀座,有利于维修和维护。
2.阀芯和阀杆采用一体式结构避免了插销式的缺陷,即使在高压差的情况下更能保证阀杆的稳定性;
3.在整个流量和特性范围内,平衡型和非平衡型阀塞,具有很高的切断密封性能;
4.金属密封和软密封具有相同的流量系数;
5.调节阀中采用平衡阀塞,可以承受比较大的允许压差;
6阀内件表面特殊处理;拋光、氮化和堆焊司钛莱合金延长了调节阀的使用寿命,工作更为可靠;
7.可调比50:1,可定制100:1;
8.采用高等级的非石棉密封或波纹管密封;
9.采用多弹簧型气动执行机构,可实现正、反作用,不需要增加其它零件就能调整弹簧范围,正作用执行机构可以实现气闭操作,反作用执行机构可实现气开操作;
10.可配气动执行机构、电动执行机构、电液动执行机构。
