气动阀门的介绍
Introduction of pneumatic valve
1、检查气动阀的型号和参数是否满足现场安装需要和技术要求。
1. Check whether the model and parameters of the pneumatic valve meet the on-site installation needs and technical requirements.
2、检查气缸和气动阀的位置指示器，确保没有损坏。
2. Check the position indicators of the cylinder and pneumatic valve to ensure that they are not damaged.
3、清洗、吹扫气动阀管路;如果介质中有杂质，应在阀门前面的管道上安装过滤阀。
3. Clean and purge the pneumatic valve pipeline; If there are impurities in the medium, a filter valve should be installed on the pipe in front of the valve.
4、按气动阀体上箭头指示的方向安装(下游安装)，将气动阀接口与管道连接，并确保连接密封良好。
4. Install in the direction indicated by the arrow on the pneumatic valve body (downstream installation), connect the pneumatic valve interface with the pipeline, and ensure that the connection is well sealed.
5、如果安装了电磁阀，注意确保接头密封良好。
5. If a solenoid valve is installed, take care to ensure that the connector is properly sealed.
6、当需要焊接连接时，高温不得传递到气动阀的填料上。
6. When welding connection is required, high temperature shall not be transferred to the packing of pneumatic valve.
气动阀门和电磁阀安装注意事项
Precautions for installation of pneumatic valve and solenoid valve
1、确保流体和气源清洁，防止堵塞电磁阀或气缸活塞。
1. Make sure that the fluid and air supply are clean to prevent plugging the solenoid valve or cylinder piston.
2、电磁阀线圈带电，正常运行时热量高。不要触摸它。
2. The solenoid valve coil is electrified and has high heat during normal operation. Don't touch it.
3、电磁阀线圈充电时，禁止拆卸，以防触电。
3. When charging the solenoid valve coil, do not disassemble it to prevent electric shock.
4、严禁撞击、碰撞电磁阀的线圈、插座、电磁管及连接部位，以免损坏。
4. It is strictly forbidden to strike or collide the coil, socket, solenoid pipe and connection part of the solenoid valve to avoid damage.
5、电磁阀线圈充电时，严禁将其盖住，以防过热和燃烧。
5. When charging the solenoid valve coil, it is strictly prohibited to cover it to prevent overheating and burning.
电磁阀的实际电源电压不得超过公差范围。
The actual supply voltage of the solenoid valve must not exceed the tolerance range.
7、介质的工作压力、温度和粘度不得超过规定范围。
7. The working pressure, temperature and viscosity of the medium shall not exceed the specified range.

气动阀门的维护方法
Maintenance method of pneumatic valve
1、在拆卸气动阀之前，应排空气缸内的液体，并释放阀内的介质压力;如果介质为高温、高压、易燃、易爆、有毒或腐蚀性介质，则要将其移除，以防止人员和设备受伤。
1. Before disassembling the pneumatic valve, drain the liquid in the air cylinder and release the medium pressure in the valve; If the medium is high temperature, high pressure, flammable, explosive, toxic or corrosive, it shall be removed to prevent injury to personnel and equipment.
2、气动阀的拆卸步骤：
2. Disassembly steps of pneumatic valve:
A、 拆卸气缸：拆下锁环，抬起并拆下气缸，然后可以看到活塞、弹簧、位置指示器、阀杆等部件。
A. Dismantle the cylinder: remove the lock ring, lift and remove the cylinder, and then you can see the piston, spring, position indicator, valve rod and other components.
B、 拆除阀体：使用扳手将其夹在阀盖根部，然后旋转以拆除阀体，并查看阀体内部。
B. Dismantle the valve body: use a wrench to clamp it at the root of the bonnet, then rotate it to remove the valve body and view the inside of the valve body.
C、 拆卸密封件：拆卸阀体后，可以看到阀杆末端的密封件。拧下固定密封件的螺钉，拆卸密封件。
C. Disassembling seals: After disassembling the valve body, the seals at the end of the valve stem can be seen. Unscrew the screws fixing the seal and remove the seal.
3、根据故障分析处理拆下的阀门。
3. Handle the removed valve according to the fault analysis.
4、处理后按拆卸步骤一次性安装。
4. After treatment, it shall be installed once according to the disassembly steps.
5、密封件、锁环、密封圈、弹簧等部件要安装到位，拧紧接头时应力均匀。在拆卸和安装过程中，小心不要损坏隔膜和阀座。
5. Seals, lock rings, seal rings, springs and other components shall be installed in place, and the stress shall be uniform when tightening the joints. Be careful not to damage the diaphragm and valve seat during disassembly and installation.
6、修复后的阀门应进行试压和泄漏试验。无异常后方可安装使用。
6. The repaired valve shall undergo pressure test and leakage test. It can be installed and used only after there is no abnormality.
