五：结构 / Structure

阀门电动装置有六个部分组成，电机，减速器,控制机构，手-电动切换机构，手轮部件及电气部分,其传动原理见图一。

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.

转矩 : Torque mechanism

图一传动原理图

Figure 1 Transmission schematic diagram

1. 电动机：采用YDF2-W户夕卜型三相异步电机，该电机为短时工作制，额定持续工作时间为10分钟。

2. 减速器:由一对正齿轮和蜗轮付组成，电动机的动力经减速器传递给输出轴。

3. 控制机构:由转矩控制机构，行程控制机构及可调式开度指示器组成，用以控制阀门的开启和关闭及阀位指示。

(1)转诚制机构(图二一)：由曲拐，挡块，凸轮分度盘，支板和微动开关组成，当输出轴受到一定阻转矩后，蜗杆除礫夕卜，还产生轴向位移,带动曲拐旋转，同时使挡块也产生一个角位移,从而迫近凸轮，使支板上抬。当输出轴上的转矩増大到预定值时，则支板上抬直至微动开关动作，切断电源，电机停转，以实现对电动装置输出转矩的控制。

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 adjustable 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.

曲拐:Crank	关向凸轮：Closed cam	开调整轴：Adjusting shaft	开向：Open direction
分度盘:Dividing disc	开向凸轮：Open cam

（2）行程控制机构（图二二）：由十进位齿轮组，顶杆，凸轮和微动开关组成，简称计数器。其工作原理是由减速箱内

的一主动小齿轮（Z=8 ）带动计数器工作。如果计数器按阀门开或关的位置已经调整好，当计数器随输出轴转到预先调整好的位置（圈数）时，则凸轮将被转动90。，压迫微动开关动作，切断电源,电机停转，壹实现对电动装置行程（圈数）的控制。为了控制较多转圈数的阀门，可调整凸轮转180。或270。再压迫微动开关动作。

(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 (number 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)可调式开度指示器(图三)：由减速齿轮组，调节齿轮，阀门开度表盘，凸轮，微动开关，及电位器组成。在现场调试时，可根据所配阀门开关的圈数，将调节齿轮调整到所需的位置，并与减速齿轮组啮合(在立柱上有所需圈数的数字)。当阀门在开启或关闭的过程中，开度盘经减速后转动，指示阀门的开关量，指示角度与阀门开关量同步，供远传指示阀门位置用。

(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.

图四手-电动切换机构

压簧:Pressure spring	中间离合器：Intermediate clutch	蜗轮：Worm gear
切换轴：Switching axis	切换手柄：Handover handle	蜗杆：Worm
育立杆:Upright pole	手轮:Handwheel

手-电动切换机构(图四)：为半自动切换，电动转变为手动操作需扳动切换手柄，由手动转变为自动时系自行进行(不需要扳动切换手柄)。由电动变为手动时，即用人工扳动切换手柄,使输出轴上的中间离合器向上移动,压迫弹簧。当手柄推到一定位置时之间离合器脱离蜗轮与手动轴爪啮合，则可使手轮上的作用力通过中间离合器传到输出轴上，即成为手动状态。手动变为电动时自动切换，当电机旋转带动蜗轮转动时直立杆立即倒下，在压簧作用下中间离合器迅速向蜗轮方向移动 ,与手动轴脱开，与蜗轮啮合，则成为电动状态。

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.
