综上所述,该一种可调节的金属气动蝶阀用阀座,使用时,首先,根据使用环境要求或者阀腔104内部流质压强选用单租气泵或者双气泵,选定供能气泵之后,将气泵的抽气管接通至于气动组件3中气闭室305两侧的抽气孔311上,再将气泵的吸气管接通至于气闭室305两侧的接气孔310上,通过螺栓分别由阀体组件1中的阀门接座101上的对接孔102进行穿出并固定于管道上,使得管道处于流通状态,将气动组件3通过螺栓穿过于底圈座303以及安装圈106上的螺栓孔107内并拧紧,可将气动组件3固定于阀体组件1上,之后,打开气泵开关,气泵开始工作,并通过气动组件3中的气闭室305左侧的抽气孔311将栓塞306左侧的气体抽出气闭室305内部,并通过气泵加压由气闭室305右侧的接气孔310压入栓塞306右侧的气闭室305中,此时,由于气闭室305内部的气压发生变化,气闭室305内部左侧气压明显低于右侧气压,栓塞306开始有气闭室305的中部逐渐向气闭室305的左侧开始移动,同时,栓塞306两侧外围的气密胶圈308紧密贴合气闭室305内壁,防止栓塞306两侧的气体互通造成内部气压平衡,连接柱307两端的栓塞306同时向气闭室305的左侧移动,底部齿板309对栓塞306以及连接柱307向左移动,并与蝶阀组件2中阀门杆203顶端的调节齿轮206相互啮合,带动阀门杆203以及底部的阀片202旋转,阀腔104内部的阀片202逐渐转动至与流质流动方向平行,管道内部形成通路,即可实现阀体开启状态,当气泵线停止运转,之后再向气闭室305左侧的接气孔310压入气体并向气闭室305右侧的抽气孔311内抽取空气时,此时气闭室305内部右侧气压低于左侧气压,栓塞306开始向右移动并带动底部的齿板309与调节齿轮206啮合,并带动阀门杆203以及阀片202反向旋转,直至复位,完成对阀腔104内部流体的分隔,阻断流通。
