进口气动真空蝶阀(德国OLES奥莱斯阀门)
【进口气动真空蝶阀】详细说明：
气动高真空蝶阀是指工作压力低于标准大气压，形成一定真空的阀门，是真空系统中用来调节气流量、切断和接通管路的元件，一般用于控制空气和非腐蚀性气体。气动真空蝶阀的阀板采用夹紧结构，把阀板的密封圈夹紧，泄露量为零，除了能用在真空状态下,也能在低压状态下使用。气动真空蝶阀以压缩空气为动力，带动碟板旋转来作启闭运动，从而达到对管路气流的接通或切断，分为双作用和单作用，单作用具有弹簧复位的作用，可在故障时自动复位。
Pneumatic high vacuum butterfly valve refers to a valve whose working pressure is lower than the standard atmospheric pressure, forming a certain vacuum. It is used to regulate air flow, cut off and connect pipelines in the vacuum system. It is generally used to control air and non-corrosive gases. The valve plate of pneumatic vacuum butterfly valve adopts clamping structure, which clamps the sealing ring of the valve plate with zero leakage. Besides being used in vacuum, it can also be used under low pressure. Pneumatic vacuum butterfly valve is powered by compressed air and drives the disc plate to rotate for opening and closing motion, so as to achieve the connection or cut-off of pipeline air flow. It can be divided into two functions and one function, which has the function of spring reset and can automatically reset in case of failure.
【进口气动真空蝶阀】特点：
- 轴承采用自润滑轴承，摩擦阻力小
2、不必从管路上拆卸阀门即可更换蝶板密封圈。
3、该阀能对介质双向截止，实现可靠的密封，双向零泄漏
4、轴封采用具有自动补偿的特殊结构，隔断外界大气与管道的连通，从而保证管道的真空度。
1. Bearings adopt self-lubricating bearings with low friction resistance.
2. The butterfly seal ring can be replaced without removing the valve from the pipeline.
3. The valve can cut off the medium in two directions, achieve reliable sealing and zero leakage in two directions.
4. Shaft seals adopt special structure with automatic compensation to isolate the connection between the outside atmosphere and the pipeline so as to ensure the vacuum of the pipeline.
