具体以下结构特点: 1、单一的弹性PTFE阀座,不必使用附加的密封圈或金属部件即能保持密封; 2、可保持双向的无泄漏密封; 3、密封设计时自动补偿了使用温度和压力的变化; 4、减少维修、延长了使用寿命。 偏置式阀杆和偏心式蝶板 1、在开启或处于任意位置时阀座与蝶板无接触; 2、减少了开启频繁时阀座上、下两面密封端的磨损; 3、减少了操作扭矩、降低了对操作机构的要求。 具有防火结构 阀门按API607标准,经过火烧试验,在发生火烧时具有密封能力。 阀杆上安装有紧定环,即使由于意外情况阀杆在阀门断裂,阀杆的上部也不会穿过紧定环落下 装卸方便 只需取下嵌件就可更换阀座,而不需拆卸蝶板和阀杆。 断流和控流性能优异 1、控制特性优异 2、流量曲线成等比变化 3、控制范围广 4、即使作为控流使用密封仍稳定 5、带凸耳式的阀门可作终端使用 |
