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 installed, pay attention to ensure that the connection is well sealed.
6.需要焊接連接時(shí)，避免高溫傳到氣動(dòng)閥的填料等處。
6. When welding connection is required, high temperature shall not be transmitted to the packing of pneumatic valve.
二、氣動(dòng)閥安裝及加裝電磁閥注意事項(xiàng)
2、 Precautions for installation of pneumatic valve and installation of 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(xiàn)圈帶電正常工作時(shí)發(fā)熱較高，請(qǐng)勿觸摸。
2. The coil of the solenoid valve is charged, and the heat is high during normal operation. Do not touch it.
3.電磁閥的線(xiàn)圈帶電時(shí)，禁止取下，以防止觸電。
3. When the coil of the solenoid valve is charged, it is forbidden to remove it to prevent electric shock.
4.電磁閥的線(xiàn)圈、插座、電磁管及連接部分，嚴(yán)禁擊打碰撞，以免損壞。
4. The coil, socket, solenoid pipe and connecting part of the solenoid valve are strictly prohibited from hitting and collision to avoid damage.
5.電磁閥的線(xiàn)圈帶電時(shí)，嚴(yán)禁覆蓋，以防過(guò)熱燒毀。
5. When the coil of the solenoid valve is charged, it is strictly prohibited to cover it to prevent overheating and burning.
6.電磁閥的實(shí)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(zhì)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(hù)方法
3、 Maintenance method
1.氣動(dòng)閥拆卸前，必須排空汽缸中的流體，泄去閥門(mén)內(nèi)介質(zhì)壓力；如果介質(zhì)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(shè)備以外傷害。
1. Before disassembling the pneumatic valve, the fluid in the cylinder must be drained to relieve the medium pressure in the valve; 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(dòng)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(jiàn)活塞、彈簧、位置指示器、閥桿等部件。
A remove the cylinder: remove the locking ring, lift up and remove the cylinder, and 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(jìn)行旋轉(zhuǎn)，即可拆卸閥體，看到閥體內(nèi)件。
B remove the valve body: use a wrench to clamp it at the root of the bonnet and rotate it to remove the valve body and see the internals of the valve body.
C 拆密封件：在拆開(kāi)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. remove the seal: after removing the valve body, you can see the seal at the end of the valve rod. Unscrew the screw fixing the seal to remove the seal.
3.根據(jù)故障分析，對(duì)拆開(kāi)的閥門(mén)進(jìn)行相應(yīng)的處理。
3. Handle the disassembled valve according to the fault analysis.
4.處理完畢，參照拆卸步驟一次安裝。
4. After treatment, install it at one time according to the disassembly steps.
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(shí)，用力要均勻。拆卸和安裝過(guò)程中要注意不要碰傷膜片和閥座。
5. Seals, locking rings, sealing rings, springs and other components must be installed in place, and the force should be even when tightening the connectors. Be careful not to damage the diaphragm and valve seat during disassembly and installation.
6.維修好的閥門(mén)，必須做試壓和滲漏等試驗(yàn)，沒(méi)有異常后才能再次安裝使用。
6. The repaired valve must be tested for pressure test and leakage, and can be installed and used again only after there is no abnormality.
