                    气动调节阀就是以压缩气体为动力源,以气缸为执行器,并借助于阀门定位器、转换器、电磁阀、保位阀、储气罐、气体过滤器等附件去驱动阀门,实现开关量或比例式调节,接?#23637;?#19994;自动化控制?#20302;?#30340;控制信号来完成调节管道介质的流量、压力、温度、液位等各?#27490;?#33402;过程参数。德国汉克(HANK)气动调节阀的特点就是控制简单,反应快速,且本质安全,不需另外再采取防爆措施。
                    安装原则
                    1、气动调节阀安装位置,距地面要求有?#27426;?#30340;高度,阀的上下要留有?#27426;?#31354;间,以便进行阀的拆装和修理。对于装有气动阀门定位器和手轮的调节阀,必须保证操作、观察和调整方便。
                    2、调节阀应安装在水平管道上,并上下与管?#26469;怪保?#19968;般要在阀下加以支撑,保证稳固可靠。对于特殊场合下,需要调节阀水平安装在竖直的管道上时,也应将调节阀进行支撑(小口径调节阀除外)。安装时,要避免给调节阀带来附加应力)。
                    3、调节阀的工作环境温度要在(-30~+60)相对湿度不大于95%。
                    4、调节阀前后位置应有直管段,长度不小于10倍的管道直径(10D),以避免阀的直管段太短而影响流量特性。
                    5、调节阀的口径与工?#23637;?#36947;不相同时,应采用异径管连接。在小口径调节阀安装时,可用螺纹连接。阀体上流体方向箭头应与流体方向一致。
                    6、要设?#38376;?#36890;管道。目的是便于切换或手动操作,可在不停车情况下对调节阀进行检修。
                    7、调节阀在安装前要彻底清除管道内的异物,如污垢、焊渣等。
                    使用注意事项
                    1、本阀应存放在干燥的室内,通路两端必须堵塞。不?#32423;?#32622;存放
                    2、长期存放的调节阀应定期检查,清除污垢,在各运动部分及加工面上应涂以防锈?#20572;?#38450;止生锈。
                    3、本阀应安装在水平管道上,必修垂直安装。阀杆向上。
                    4、必修按图示箭头所指示介质流动方向进行安装。
                    Pneumatic control valve is to compressed gas as the power source to the cylinder as the actuator, and by means of the valve positioner, converter, solenoid valve, security valve, gas tank, gas filter and other accessories to drive the valve, to achieve switch Or proportional adjustment, receiving the industrial automation control system control signal to complete the regulation of pipeline media flow, pressure, temperature, liquid level and other process parameters. Germany Hank (HANK) pneumatic control valve is characterized by simple control, rapid response, and intrinsically safe, no need to take another explosion-proof measures.
                    Installation principle
                    1, pneumatic valve installation location, from the ground requires a certain height, the valve up and down to leave a certain space in order to carry out the valve disassembly and repair. For the control valve with pneumatic valve positioner and hand wheel, it is necessary to ensure easy operation, observation and adjustment.
                    2, the control valve should be installed in the horizontal pipe, and vertical and vertical pipe, generally under the valve to be supported to ensure a solid and reliable. For special occasions, the need to adjust the valve installed in the vertical pipe, the control valve should also be supported (except for small diameter control valve). Installation, to avoid additional stress to the control valve).
                    3, the operating temperature of the control valve to (-30 ~ +60) relative humidity of not more than 95%.
                    4, the front and rear position of the control valve should be straight pipe, the length of not less than 10 times the diameter of the pipe (10D), in order to avoid the valve straight pipe section is too short and affect the flow characteristics.
                    5, the diameter of the valve and the process pipeline is not the same, should be used to connect the reducer. In the small diameter control valve installation, available thread connection. The direction of the fluid on the valve body should be consistent with the direction of the fluid.
                    6, to set the bypass pipe. The purpose is to facilitate switching or manual operation, in the case of non-stop control valve for maintenance.
                    7, the control valve in the installation before the complete removal of foreign bodies in the pipeline, such as dirt, welding slag and so on.
                    Precautions for use
                    1, the valve should be stored in a dry room, the two ends must be blocked. Not allowed to store storage
                    2, long-term storage of the control valve should be regularly checked, remove the dirt, in the movement part and the processing surface should be coated with anti-rust oil to prevent rust.
                    3, the valve should be installed in the horizontal pipe, compulsory vertical installation. Stem up.

                    4, compulsory according to the arrows indicated by the direction of the media flow direction to install.
