氣動調節閥就是以壓縮氣體為動力源,以氣缸為執行器,并借助于閥門定位器、轉換器、電磁閥、保位閥、儲氣罐、氣體過濾器等附件去驅動閥門,實現開關量或比例式調節,接收工業自動化控制系統的控制信號來完成調節管道介質的流量、壓力、溫度、液位等各種工藝過程參數。德國漢克(HANK)氣動調節閥的特點就是控制簡單,反應快速,且本質安全,不需另外再采取防爆措施。
安裝原則
1、氣動調節閥安裝位置,距地面要求有一定的高度,閥的上下要留有一定空間,以便進行閥的拆裝和修理。對于裝有氣動閥門定位器和手輪的調節閥,必須保證操作、觀察和調整方便。
2、調節閥應安裝在水平管道上,并上下與管道垂直,一般要在閥下加以支撐,保證穩固可靠。對于特殊場合下,需要調節閥水平安裝在豎直的管道上時,也應將調節閥進行支撐(小口徑調節閥除外)。安裝時,要避免給調節閥帶來附加應力)。
3、調節閥的工作環境溫度要在(-30~+60)相對濕度不大于95%。
4、調節閥前后位置應有直管段,長度不小于10倍的管道直徑(10D),以避免閥的直管段太短而影響流量特性。
5、調節閥的口徑與工藝管道不相同時,應采用異徑管連接。在小口徑調節閥安裝時,可用螺紋連接。閥體上流體方向箭頭應與流體方向一致。
6、要設置旁通管道。目的是便于切換或手動操作,可在不停車情況下對調節閥進行檢修。
7、調節閥在安裝前要徹底清除管道內的異物,如污垢、焊渣等。
使用注意事項
1、本閥應存放在干燥的室內,通路兩端必須堵塞。不準堆置存放
2、長期存放的調節閥應定期檢查,清除污垢,在各運動部分及加工面上應涂以防銹油,防止生銹。
3、本閥應安裝在水平管道上,必修垂直安裝。閥桿向上。
4、必修按圖示箭頭所指示介質流動方向進行安裝。
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.
