氣動閥門的介紹
Introduction of pneumatic valve
1、檢查氣動閥的型號和參數是否滿足現場安裝需要和技術要求。
1. Check whether the model and parameters of the pneumatic valve meet the on-site installation needs and technical requirements.
2、檢查氣缸和氣動閥的位置指示器,確保沒有損壞。
2. Check the position indicators of the cylinder and pneumatic valve to ensure that they are not damaged.
3、清洗、吹掃氣動閥管路;如果介質中有雜質,應在閥門前面的管道上安裝過濾閥。
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、按氣動閥體上箭頭指示的方向安裝(下游安裝),將氣動閥接口與管道連接,并確保連接密封良好。
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、如果安裝了電磁閥,注意確保接頭密封良好。
5. If a solenoid valve is installed, take care to ensure that the connector is properly sealed.
6、當需要焊接連接時,高溫不得傳遞到氣動閥的填料上。
6. When welding connection is required, high temperature shall not be transferred to the packing of pneumatic valve.
氣動閥門和電磁閥安裝注意事項
Precautions for installation of pneumatic valve and solenoid valve
1、確保流體和氣源清潔,防止堵塞電磁閥或氣缸活塞。
1. Make sure that the fluid and air supply are clean to prevent plugging the solenoid valve or cylinder piston.
2、電磁閥線圈帶電,正常運行時熱量高。不要觸摸它。
2. The solenoid valve coil is electrified and has high heat during normal operation. Don't touch it.
3、電磁閥線圈充電時,禁止拆卸,以防觸電。
3. When charging the solenoid valve coil, do not disassemble it to prevent electric shock.
4、嚴禁撞擊、碰撞電磁閥的線圈、插座、電磁管及連接部位,以免損壞。
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、電磁閥線圈充電時,嚴禁將其蓋住,以防過熱和燃燒。
5. When charging the solenoid valve coil, it is strictly prohibited to cover it to prevent overheating and burning.
電磁閥的實際電源電壓不得超過公差范圍。
The actual supply voltage of the solenoid valve must not exceed the tolerance range.
7、介質的工作壓力、溫度和粘度不得超過規定范圍。
7. The working pressure, temperature and viscosity of the medium shall not exceed the specified range.

氣動閥門的維護方法
Maintenance method of pneumatic valve
1、在拆卸氣動閥之前,應排空氣缸內的液體,并釋放閥內的介質壓力;如果介質為高溫、高壓、易燃、易爆、有毒或腐蝕性介質,則要將其移除,以防止人員和設備受傷。
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、氣動閥的拆卸步驟:
2. Disassembly steps of pneumatic valve:
A、 拆卸氣缸:拆下鎖環,抬起并拆下氣缸,然后可以看到活塞、彈簧、位置指示器、閥桿等部件。
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、 拆除閥體:使用扳手將其夾在閥蓋根部,然后旋轉以拆除閥體,并查看閥體內部。
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:拆卸閥體后,可以看到閥桿末端的密封件。擰下固定密封件的螺釘,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、根據故障分析處理拆下的閥門。
3. Handle the removed valve according to the fault analysis.
4、處理后按拆卸步驟一次性安裝。
4. After treatment, it shall be installed once according to the disassembly steps.
5、密封件、鎖環、密封圈、彈簧等部件要安裝到位,擰緊接頭時應力均勻。在拆卸和安裝過程中,小心不要損壞隔膜和閥座。
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、修復后的閥門應進行試壓和泄漏試驗。無異常后方可安裝使用。
6. The repaired valve shall undergo pressure test and leakage test. It can be installed and used only after there is no abnormality.
