进口气动真空蝶阀
所属类别:真空阀  
全称:Orsen型-气动高真空蝶阀
气动真空蝶阀的主要优点,结构简单,体积小重量轻,造价低,气动蝶阀该特点尤其显著,安装在高真空管道。流体阻力较小,中大口径的气动蝶阀全开时有效流通面积较大,启闭迅速省力,碟扳旋转90角度即可完成启闭,由于转轴两侧蝶板手介质作用力接近相等,而产生的转矩方向相反,因而启闭力矩较小,低压下可实现良好的密封,蝶阀密封材料有丁晴橡胶、氟橡胶,食用橡胶,衬四氟故密封性能良好,其中硬密封蝶阀为软硬层叠式金属片具有金属硬密封和弹性密封的重优点,无论在低温情况下均具有优良的密封性能。
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.
进口气动真空特点:
1、小巧轻便,容易拆装及维修,并可在任意位置安装。
2、结构简单、紧凑,操作扭矩小,90°回转开启迅速。
3、流量特性趋直线,调节性能好。
4、蝶板与阀杆的连接采用无销钉结构,克服了有可能的内泄漏点。
5、蝶板外圆采用球面造型,提高了密封性能及延长了阀门的使用寿命,带压启闭5万次以上仍保持零泄漏。
6、密封件可更换,且密封可靠达到双向密封。
7、蝶板可根据用户要求喷涂覆层,如尼龙或聚四氟类。
8、该阀可设计成法兰连接和对夹连接。
9、驱动方式可选择手动、电动或气动。
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-气动高真空蝶阀
■Orsen型气动高真空蝶阀是通过电磁换向阀改变气路方向,控制执行气缸驱动蝶阀作启闭运动。用于接通或切断真空管路中的气流。适用介质为纯净空气和非腐蚀性气体。可选配反馈信号装置及电气阀门定位器。
■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.
