五：結構 / Structure 閥門電動裝置有六個部分組成，電機，減速器,控制機構，手-電動切換機構，手輪部件及電氣部分,其傳動原理見圖一。 The valve electric device is composed of six parts, the motor, reducer, control mechanism, hand-electric switching mechanism, hand wheel components and electrical parts. Its transmission principle is shown in Figure 1.
轉矩 : Torque mechanism 圖一傳動原理圖 Figure 1 Transmission schematic diagram 1. 電動機：采用YDF2-W戶夕卜型三相異步電機，該電機為短時工作制，額定持續工作時間為10分鐘。 2. 減速器:由一對正齒輪和蝸輪付組成，電動機的動力經減速器傳遞給輸出軸。 3. 控制機構:由轉矩控制機構，行程控制機構及可調式開度指示器組成，用以控制閥門的開啟和關閉及閥位指示。 (1)轉誠制機構(圖二一)：由曲拐，擋塊，凸輪分度盤，支板和微動開關組成，當輸出軸受到一定阻轉矩后，蝸桿除 礫夕卜，還產生軸向位移,帶動曲拐旋轉，同時使擋塊也產生一個角位移,從而迫近凸輪，使支板上抬。當輸出軸上的轉矩増大 到預定值時，則支板上抬直至微動開關動作，切斷電源，電機停轉，以實現對電動裝置輸出轉矩的控制。 1. Motor: ydf2-w outdoor three-phase asynchronous motor is adopted, which is short-time working system and rated continuous working time is 10 minutes. 2. Reducer: it consists of a pair of spur gears and worm gear pairs. The power of the motor is transmitted to the output shaft through the reducer. 3. Control mechanism: it is composed of torque control mechanism, stroke control mechanism and adjust able opening indicator to control the opening and closing of valve and indication of valve position. (1) Torque control mechanism (Fig. 2.1): it is composed of crank, stop, cam index plate, support plate and microswitch. When the output shaft is subject to certain resistance torque, the worm not only rotates, but also produces axial displacement, which drives the crank to rotate, at the same time, the stop also produces an angular displacement, so as to approach the cam and lift the support plate. When the torque on the output shaft increases to a predetermined value, the support plate is lifted until the microswitch acts, the power supply is cut off, and the motor stops running, so as to realize the control of the output torque of the electric device.
（2）行程控制機構（圖二二）：由十進位齒輪組，頂桿，凸輪和微動開關組成，簡稱計數器。其工作原理是由減速箱內 的一主動小齒輪（Z=8 ）帶動計數器工作。如果計數器按閥門開或關的位置已經調整好，當計數器隨輸出軸轉到預先調整好的 位置（圈數）時，則凸輪將被轉動90。，壓迫微動開關動作，切斷電源,電機停轉，壹實現對電動裝置行程（圈數）的控制。 為了控制較多轉圈數的閥門，可調整凸輪轉180。或270。再壓迫微動開關動作。
(2) Stroke control mechanism (Fig. 2.2): composed of decimal gear set, ejector pin, cam and microswitch, referred to as counter. The working principle of the counter is driven by a driving pinion (z = 8) in the gearbox. If the counter has been adjusted according to the opening or closing position of the valve, when the counter is turned to the pre adjusted position (number of turns) along with the output shaft, the cam will be turned 90 °, pressing the microswitch action, cutting off the power supply, stopping the motor; and realizing the control of the electric device stroke (num ber of turns). In order to control the valve with more turns, adjust the cam to rotate 180 ° or 270 ° and press the microswitch again. (3)可調式開度指示器(圖三)：由減速齒輪組，調節齒輪，閥門開度表盤，凸輪，微動開關，及電位器組成。在現場 調試時，可根據所配閥門開關的圈數，將調節齒輪調整到所需的位置，并與減速齒輪組嚙合(在立柱上有所需圈數的數字)。 當閥門在開啟或關閉的過程中，開度盤經減速后轉動，指示閥門的開關量，指示角度與閥門開關量同步，供遠傳指示閥門位置 用。 (3) Adjustable opening indicator (Figure 3): it is composed of reduction gear set, adjusting gear, valve opening dial, cam, microswitch and potentiometer. During on-site commissioning, the adjusting gear can be adjusted to the required position according to the number of turns of the valve switch, and it can mesh with the reduction gear set (there is a number of turns required on the column). In the process of opening or closing the valve, the opening plate rotates after slowing down to indicate the on-off value of the valve, and the indicating angle is synchronized with the valve on-off value for remote transmission to indicate the valve position.
Figure 4 Hand electric switching mechanism
手-電動切換機構(圖四)：為半自動切換，電動轉變為手動操作需扳動切換手柄，由手動轉變為自動時系自行進行(不 需要扳動切換手柄)。由電動變為手動時，即用人工扳動切換手柄,使輸出軸上的中間離合器向上移動,壓迫彈簧。當手柄 推到一定位置時之間離合器脫離蝸輪與手動軸爪嚙合，則可使手輪上的作用力通過中間離合器傳到輸出軸上，即成為手動狀 態。手動變為電動時自動切換，當電機旋轉帶動蝸輪轉動時直立桿立即倒下，在壓簧作用下中間離合器迅速向蝸輪方向移動 ,與手動軸脫開，與蝸輪嚙合，則成為電動狀態。 Manual electric switching mechanism (Figure 4): it is semi-automatic switching, and the switching handle needs to be pulled for electric to manual operation, and it will be carried out by itself when it is changed from manual to automatic (no need to pull the switching handle). When changing from electric to manual, manually pull the switch handle to make the intermediate clutch on the output shaft move upward and press the spring. When the handle is pushed to a certain position and the clutch disengages from the worm gear and engages with the manual shaft claw, the force on the hand wheel can be transmitted to the output shaft through the intermediate clutch, that is to say, it becomes the manual state. When it is changed from manual to electric, it will switch automatically. When the motor rotates to drive the worm gear; the upright rod will fall down immediately. Under the action of the compression spring, the intermediate clutch will move towards the worm gear quickly, and it will be separated from the manual shaft and meshed with the worm gear; which will become the electric state. 六：外形尺寸 / Dimensions CNZ05/10/15 CNZ20/30 CNZ45/60
