Lianggong valve is very prosperous in the valve industry, and many people will choose it. We are very honored to have the opportunity to cooperate with you. Here, we will explain to you what to pay attention to when installing good worker valves!

1.安装前检查良工阀门是否缺件，型号是否正确，阀体是否有杂物，消声器是否堵塞。

1. Before installation, check whether the good worker valve is missing, whether the model is correct, whether there are sundries in the valve body and whether the muffler is blocked.

2.将阀门和气缸置于关闭位置。

2. Place the valve and cylinder in the closed position.

3.将气缸安装在阀门上(装置方向与阀体平行或笔直)，然后检查螺孔是否对齐。不会有重大错误。如果有任何错误，只需轻轻转动气缸并拧紧螺钉。

3. Install the cylinder on the valve (the direction of the device is parallel or straight with the valve body), and then check whether the screw holes are aligned. There will be no major mistakes. If there are any errors, just turn the cylinder slightly and tighten the screws.

4.安装完成后，调试电磁阀(正常供气压力为0.40.6MPa)。调试时，需要手动打开和关闭电磁阀(电磁阀线圈只有在电磁阀切断后才能手动操作)，检查电磁阀的打开和关闭情况。如果在开启和关闭开始时发现阀门被强制，然后在擦洗操作期间，阀门处于正常状态，则应减小气缸的行程(同时向内调整气缸两端的行程调整螺钉)。调整过程中，将阀门操作到开启位置(然后关闭气源，再次调整)，直到阀门启闭平稳，无漏气。还应注意，可调消声器可以调节阀门的开启和关闭速度，但不能太小，否则阀门可能不会移动。

4. after installation, adjust the solenoid valve (the normal supply pressure is 0.40.6MPa). During commissioning, it is necessary to open and close the solenoid valve manually (the solenoid valve coil can be operated manually only after the solenoid valve is cut off), and check the opening and closing of the solenoid valve. If it is found that the valve is forced at the beginning of opening and closing, and then the valve is in normal state during scrubbing operation, reduce the stroke of the cylinder (and adjust the stroke adjustment screws at both ends of the cylinder inward at the same time). During the adjustment, operate the valve to the open position (then close the air source and adjust again) until the valve opens and closes smoothly without air leakage. It should also be noted that the adjustable muffler can adjust the opening and closing speed of the valve, but it should not be too small, otherwise the valve may not move.

5.安装前务必保持干燥，不要露天存放。

5. Be sure to keep dry before installation and do not store in the open air.

6.安装良工阀门前检查管道，确保管道内无焊渣和其他异物。

6. Check the pipeline before installing the good worker valve to ensure that there is no welding slag and other foreign matters in the pipeline.

7.节气门体手动启闭阻力适中，节气门扭矩与所选执行器扭矩匹配。

7. The manual opening and closing resistance of the throttle body is moderate, and the throttle torque matches the torque of the selected actuator.

8.良工阀门连接法兰标准正确，管卡法兰符合良工阀门法兰标准。良工阀门应使用专用法兰，而不是焊接平法兰。

8. The connecting flange standard of Lianggong valve is correct, and the pipe clamp flange meets the flange standard of Lianggong valve. Valves of good workmanship shall use special flanges instead of welded flat flanges.

9.确认法兰焊接正确。安装良工阀门后，不要焊接法兰，以免烧坏橡胶件。

9. Confirm that the flange is welded correctly. After installing the Lianggong valve, do not weld the flange to avoid burning the rubber parts.

10.安装的法兰需要对齐并插入良工阀门。

10. The installed flange needs to be aligned and inserted into the Lianggong valve.

11.安装所有法兰螺栓并用手拧紧。您会发现良工阀门和法兰已经对齐，然后小心地打开和关闭良工阀门，以确保灵敏的打开和关闭。

11. Install all flange bolts and tighten them by hand. You will find that the Lianggong valve and flange are aligned, and then carefully open and close the Lianggong valve to ensure sensitive opening and closing.

12.全开阀门，用不带垫圈的扳手对角拧紧螺栓，不要过度拧紧螺栓，以免阀环严重变形和启闭扭矩过大。

12. Fully open the valve and tighten the bolts diagonally with a wrench without washer. Do not over tighten the bolts to avoid serious deformation of the valve ring and excessive opening and closing torque.
