三、進口氣動調(diào)節(jié)蝶閥結(jié)構(gòu)特點：

1．氣動蝶閥操作力矩小，是所有閥類中操作力矩最小的一種，啟閉迅速，以壓縮空氣為動力，通過活塞齒條，齒輪的機械傳動閥桿，以角行程輸出的扭矩轉(zhuǎn)動閥板0~90°，就能快速的完成啟閉動作，結(jié)構(gòu)簡單、體積小、重量輕、流阻小、流量系數(shù)大，密封性能好。調(diào)節(jié)范圍大。是自動化控制系統(tǒng)中儀表的執(zhí)行單元。

 2．采用電-氣閥門定位器，以電信號和壓縮空氣為動力，接受控制系統(tǒng)輸入的0-10mA DC或4-20mA DC電流信號，由調(diào)節(jié)器將壓縮空氣，轉(zhuǎn)換成氣源壓力信號輸入輸出，改變閥板的旋轉(zhuǎn)角度（0-90° 任意角度），具有較好的調(diào)節(jié)控制流量等參數(shù)。

3．采用電磁換向閥、閥位回訊器，以AC220V或DC24V電源電壓和壓縮空氣作動力，實現(xiàn)對流體介質(zhì)的快速二位切斷控制。

4．氣動執(zhí)行機構(gòu)采用活塞式氣缸及曲臂轉(zhuǎn)換結(jié)構(gòu)，輸出力矩大，體積精小，采用全密封防水設計防護等級高。氣缸體采用鏡面氣缸，無油潤滑，磨擦系數(shù)小、耐腐蝕、具有超強的耐用性及可靠性。所有傳動軸承均采用邊界自潤滑軸承無油潤滑，確保傳動軸不摩損。

1. The pneumatic butterfly valve has a small operating torque, which is the smallest one among all valve categories. It can be opened and closed quickly. With compressed air as power, it can quickly complete the opening and closing action by rotating the valve plate 0 ~ 90 ° with the torque output from the angle stroke through the mechanical transmission valve rod of the piston rack and gear. It has simple structure, small volume, light weight, small flow resistance, large flow coefficient and good sealing performance. Large adjustment range. It is the execution unit of the instrument in the automatic control system.

2. The electric pneumatic valve positioner is used to receive the 0-10mA DC or 4-20mA DC current signal input by the control system with the electric signal and compressed air as the power. The regulator converts the compressed air into the air source pressure signal input and output, changes the rotation angle of the valve plate (0-90 ° arbitrary angle), and has better parameters such as regulating and controlling the flow.

3. Adopt electromagnetic reversing valve and valve position return device, and use AC220V or DC24V power supply voltage and compressed air as power to realize fast two position cut-off control of fluid medium.

4. The pneumatic actuator adopts piston type cylinder and crank arm conversion structure, with large output torque, small volume and high protection level of full sealing and waterproof design. The cylinder body adopts mirror cylinder, no oil lubrication, small friction coefficient, corrosion resistance, super durability and reliability. Boundary self-lubricating bearing without oil lubrication is adopted for all transmission bearings to ensure that the transmission shaft is not damaged.
