進口氣動真空蝶閥(德國OLES奧萊斯閥門)

【進口氣動真空蝶閥】詳細說明：

氣動高真空蝶閥是指工作壓力低于標準大氣壓，形成一定真空的閥門，是真空系統中用來調節氣流量、切斷和接通管路的元件，一般用于控制空氣和非腐蝕性氣體。氣動真空蝶閥的閥板采用夾緊結構，把閥板的密封圈夾緊，泄露量為零，除了能用在真空狀態下,也能在低壓狀態下使用。氣動真空蝶閥以壓縮空氣為動力，帶動碟板旋轉來作啟閉運動，從而達到對管路氣流的接通或切斷，分為雙作用和單作用，單作用具有彈簧復位的作用，可在故障時自動復位。

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.

【進口氣動真空蝶閥】特點：

1. 軸承采用自潤滑軸承，摩擦阻力小

2、不必從管路上拆卸閥門即可更換蝶板密封圈。

3、該閥能對介質雙向截止，實現可靠的密封，雙向零泄漏

4、軸封采用具有自動補償的特殊結構，隔斷外界大氣與管道的連通，從而保證管道的真空度。

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.

【進口氣動真空蝶閥】工作原理：

氣動真空蝶閥由氣動活塞式執行機構與真空蝶閥組合構成。
