Pneumatic lining fluorine butterfly valve: the anti-corrosion lining fluorine butterfly valve is divided into two valve body combinations. The valve seat and valve body lining are integrated. The valve works. Only the plastic valve seat and lining plastic butterfly plate are in contact with the medium. The product can withstand the corrosion of any medium other than molten alkali metal and elemental fluorine, including d71f46 valve stem and butterfly plate (forging), and the surface is evenly covered with a layer of FEP. The inner surface of the valve body channel is smooth, the fluid resistance is small, the CV value is high, the circulation capacity is strong, and the torque is moderate. The four-stage sealing structure is adopted, and the temperature and aging resistant Si rubber elastic gasket valve seat is adopted to completely realize zero medium leakage.
气动通风蝶阀:阀板阀座间有一条细缝,适用于空气流通较差的环境。
Pneumatic ventilation butterfly valve: there is a fine seam between the valve plate and valve seat, which is suitable for the environment with poor air circulation.
气动伸缩蝶阀:设计新颖,结构合理,结构独特,重量轻,操作方便,启闭快;伸缩蝶阀不仅可以调节和截流,补偿管道温差引起的热膨胀和冷收缩功能,还可以方便安装和更换和维护阀门。密封件可调更换,密封性能可靠。
Pneumatic telescopic butterfly valve: novel design, reasonable structure, unique structure, light weight, convenient operation and fast opening and closing; The telescopic butterfly valve can not only adjust and shut off the flow and compensate the thermal expansion and cold contraction caused by the pipeline temperature difference, but also facilitate the installation, replacement and maintenance of the valve. The seal can be adjusted and replaced, and the sealing performance is reliable.
气动硬密封蝶阀:结构简单,体积小,重量轻,成本低。气动盘阀的特点特别明显。安装在高空黑暗道路上。经过两个五通电磁阀控制,操作方便,流量介质也可调节。流体阻力小,中大口径气动盘阀全开时循环面积大,启闭快捷省力,盘扳机旋转90角度即可完成启闭。由于转轴两侧盘板手介质的作用力接近相等,转矩方向相反,启闭扭矩小,低压下密封良好。盘阀密封材料包括丁青橡胶、氟橡胶、食用橡胶和衬四氟化物,因此密封性能良好。硬密封盘阀是软硬层叠金属片,具有金属硬密封和弹性密封的优点,在低温下密封性能优异。
Pneumatic hard seal butterfly valve: simple structure, small volume, light weight and low cost. The characteristics of pneumatic disc valve are particularly obvious. Installed on high-altitude dark roads. Controlled by two five way solenoid valves, the operation is convenient, and the flow medium can also be adjusted. Small fluid resistance, large circulation area when the medium and large diameter pneumatic disc valve is fully opened, fast and labor-saving opening and closing, and the opening and closing can be completed by turning the trigger 90 degrees. As the force of the medium on both sides of the rotating shaft is nearly equal, the torque direction is opposite, the opening and closing torque is small, and the sealing is good under low pressure. Disc valve sealing materials include butadiene rubber, fluororubber, edible rubber and lining tetrafluoride, so the sealing performance is good. Hard seal disc valve is a soft and hard laminated metal sheet, which has the advantages of metal hard seal and elastic seal. It has excellent sealing performance at low temperature.
