氣動閥門的安裝及使用要求有哪些?

來源:http://www.serviceforo.com/ 日期:2023-02-15 發(fā)布人:admin
1.檢查氣動閥門的型號,參數是否符合現場安裝需要和技術要求。
1. Check whether the model and parameters of the pneumatic valve meet the site installation requirements and technical requirements.
2.檢查氣動閥門的氣缸、位置指示器,確保無損傷。
2. Check the air cylinder and position indicator of the pneumatic valve to ensure there is no damage.
3.必須把氣動閥的管道清洗、吹掃干凈;如介質內有雜質,在閥前管道上應加裝過濾閥。
3. The pipeline of pneumatic valve must be cleaned and purged; If there are impurities in the medium, a filter valve should be installed on the pipeline in front of the valve.
4.按氣動閥閥體上箭頭指示的方向安裝(順流安裝)把氣動閥門的接口與管道連接上,并確保連接處良好的密封。
4. Install in the direction indicated by the arrow on the pneumatic valve body (downstream installation), connect the interface of the pneumatic valve with the pipeline, and ensure that the connection is well sealed.
5.如加裝電磁閥,注意連接處確保密封良好。
5. If a solenoid valve is added, pay attention to ensure that the connection is well sealed.
6.需要焊接連接時,避免高溫傳到氣動閥的填料等處。
6. When welding connection is required, avoid high temperature being transmitted to the packing of pneumatic valve.
二、氣動閥安裝及加裝電磁閥注意事項
2、 Precautions for installing pneumatic valve and adding solenoid valve
1.必須保證流體、氣源潔凈,以防堵塞電磁閥或氣缸活塞。
1. The fluid and air source must be clean to prevent blocking the solenoid valve or cylinder piston.
2.電磁閥的線圈帶電正常工作時發(fā)熱較高,請勿觸摸。
2. When the coil of the solenoid valve is electrified and works normally, the heat is high. Do not touch it.

3.電磁閥的線圈帶電時,禁止取下,以防止觸電。
3. When the solenoid valve coil is electrified, it is forbidden to take it down to prevent electric shock.
4.電磁閥的線圈、插座、電磁管及連接部分,嚴禁擊打碰撞,以免損壞。
4. The coil, socket, solenoid pipe and connecting part of the solenoid valve shall not be hit or collided to avoid damage.
5.電磁閥的線圈帶電時,嚴禁覆蓋,以防過熱燒毀。
5. When the solenoid valve coil is electrified, it is forbidden to cover it to prevent overheating and burning.
6.電磁閥的實際電源電壓不能超出公差范圍。
6. The actual power supply voltage of the solenoid valve shall not exceed the tolerance range.
7.介質工作壓力,工作溫度、黏度,不得超出規(guī)定的范圍。
7. The working pressure, temperature and viscosity of the medium shall not exceed the specified range.
三、維護方法
3、 Maintenance method
1.氣動閥拆卸前,必須排空汽缸中的流體,泄去閥門內介質壓力;如果介質是高溫、高壓易燃、易爆,有毒或者有腐蝕性,必須徹底清除,以防造成人身、設備以外傷害。
1. Before disassembling the pneumatic valve, the fluid in the cylinder must be drained and the medium pressure in the valve must be relieved; If the medium is high temperature, high pressure, flammable, explosive, toxic or corrosive, it must be completely removed to prevent personal and equipment injury.
2.氣動閥拆卸步驟:
2. Disassembly steps of pneumatic valve:
A 拆汽缸:取下鎖緊環(huán),向上提起并取下汽缸后,可以看見活塞、彈簧、位置指示器、閥桿等部件。
A Dismantle the cylinder: remove the locking ring, lift up and remove the cylinder, and then you can see the piston, spring, position indicator, valve rod and other components.
B 拆閥體:用扳手卡在閥蓋根部進行旋轉,即可拆卸閥體,看到閥體內件。
B Dismantle the valve body: use a wrench to clamp it at the root of the bonnet and rotate it to disassemble the valve body and see the valve body internals.
C 拆密封件:在拆開閥體后,可以看到在閥桿末端的密封件,擰下固定密封件的螺絲,即可拆下密封件。
C Dismantle the seal: after disassembling the valve body, you can see the seal at the end of the valve rod. Unscrew the screw that fixes the seal to remove the seal.
3.根據故障分析,對拆開的閥門進行相應的處理。
3. According to the fault analysis, handle the disassembled valve accordingly.
4.處理完畢,參照拆卸步驟一次安裝。
4. After handling, install it once according to the removal procedure.
5.密封件、鎖緊環(huán)、密封環(huán)和彈簧等部件一定要安裝到位,擰緊連接件時,用力要均勻。拆卸和安裝過程中要注意不要碰傷膜片和閥座。
5. The components such as seals, locking rings, sealing rings and springs must be installed in place. When tightening the connectors, the force should be even. Pay attention not to damage the diaphragm and valve seat during removal and installation.
6.維修好的閥門,必須做試壓和滲漏等試驗,沒有異常后才能再次安裝使用。
6. The repaired valve must undergo pressure test and leakage test, and can be installed and used again after there is no abnormality.
