进口气动对焊，承插焊球阀的作用形式分为双作用和单作用，单作用形式具有弹簧复位功能，可在遇到故障或没有气源时，自动
归位到开启或关闭的状态。气动三片式球阀通过压缩空气为动力源，带动阀芯做0-90度的来回转动，即可实现对阀门的开关动作，在各个行业得到广泛应用，是常见的控制阀门 RETZ The functions of imported pneumatic butt welding and socket welding ball valves are divided into double acting and single acting. The single acting form has the function of spring return, which can automatically return to the open or closed state in case of failure or no air source. The pneumatic three piece ball valve uses compressed air as the power source to drive the valve core to rotate back and forth at 0-90 degrees, which can realize the opening and closing of the valve. It is widely used in various industries and is a common control valve
