進口氣動真空蝶閥

所屬類別：真空閥  

全稱：Orsen型-氣動高真空蝶閥

氣動真空蝶閥的主要優點，結構簡單，體積小重量輕，造價低，氣動蝶閥該特點尤其顯著，安裝在高真空管道。流體阻力較小，中大口徑的氣動蝶閥全開時有效流通面積較大，啟閉迅速省力，碟扳旋轉90角度即可完成啟閉，由于轉軸兩側蝶板手介質作用力接近相等，而產生的轉矩方向相反，因而啟閉力矩較小，低壓下可實現良好的密封，蝶閥密封材料有丁晴橡膠、氟橡膠，食用橡膠，襯四氟故密封性能良好，其中硬密封蝶閥為軟硬層疊式金屬片具有金屬硬密封和彈性密封的重優點，無論在低溫情況下均具有優良的密封性能。

The main advantage of the vacuum pneumatic butterfly valve, simple structure, small size, light weight, low cost, pneumatic butterfly This feature was particularly notable, installed in a high vacuum line. Fluid resistance is small, while the large-diameter pneumatic valve fully open and effective flow of larger, open and close rapidly effort, pull the disc rotation angle of 90 to complete the opening and closing, due to the media on both sides of the shaft butterfly wrench force nearly equal, and the torque generated by the opposite direction, so the smaller opening and closing torque, low pressure can achieve a good seal, valve seal materials NBR, Viton, edible rubber, PTFE lining so good sealing performance, which is a soft seal butterfly advantages hard heavy metal sheets stacked with a metal seal and a resilient seal, both at low temperatures have excellent sealing properties.

進口氣動真空特點：

1、小巧輕便，容易拆裝及維修，并可在任意位置安裝。

2、結構簡單、緊湊，操作扭矩小，90°回轉開啟迅速。

3、流量特性趨直線，調節性能好。

4、蝶板與閥桿的連接采用無銷釘結構，克服了有可能的內泄漏點。

5、蝶板外圓采用球面造型，提高了密封性能及延長了閥門的使用壽命，帶壓啟閉5萬次以上仍保持零泄漏。

6、密封件可更換，且密封可靠達到雙向密封。

7、蝶板可根據用戶要求噴涂覆層，如尼龍或聚四氟類。

8、該閥可設計成法蘭連接和對夾連接。

9、驅動方式可選擇手動、電動或氣動。

Imported pneumatic vacuum features:

1, small, lightweight, easy installation and maintenance, and can be mounted in any position.

2, the structure is simple, compact, low operating torque, 90 ° swing open quickly.

3, the flow characteristics of linear trend, regulated performance.

4, the disc-free connection with the stem pin structure, it is possible to overcome the internal leaks.

5, using the spherical shape of the outer disc, improved sealing performance and extend the life of the valve, with pressure hoist more than 50,000 times remain zero leakage.

6, the seals can be replaced, and achieve bi-directional sealing reliable sealing.

7, the disc can be sprayed coatings based on user requirements, such as nylon or PTFE classes.

8, the valve can be designed into flanged and wafer.

9, drive optional manual, electric or pneumatic.

■Orsen型－氣動高真空蝶閥

■Orsen型氣動高真空蝶閥是通過電磁換向閥改變氣路方向，控制執行氣缸驅動蝶閥作啟閉運動。用于接通或切斷真空管路中的氣流。適用介質為純凈空氣和非腐蝕性氣體。可選配反饋信號裝置及電氣閥門定位器。

■Orsen Pneumatic High Vacuum Butterfly Valve

■Orsen pneumatic high vacuum butterfly valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the butterfly valve opened and closed. It is used to put through or cut off the airflow in vacuum pileline. Applicable medium can be pure air and noncorrosive gases. They may be fitted with signal feedback device and electropneumatic valve positioner.
