燃氣電磁閥安裝方式:
1. 閥門安裝單位應具備相應資質并按相關的燃氣管道施工規(guī)范安裝。
2. 閥門應安裝在戶內的總進氣閥之后,以便檢修。
3. 應按閥體標明的氣流方向安裝,閥體線圈不得倒立,允許水平和垂直安裝。
4. 電磁閥控制線應正確可靠連接,控制線有極性:白色線為正極黑色線為負極,不能接反。
5. 管道吹掃時,建議將電磁閥隔離,以免管內雜物損壞閥門密封材料。
6. 管道在進行試壓檢測密封性能前,應先使電磁閥處開閥狀態(tài)。
7. 手動開閥時,宜在閥門進出口壓力平衡時操作。
8. 電動關閥時,切忌接錯電源,如:接錯極性、加錯電壓或長時間通電等,以免損壞電磁線圈。

Gas solenoid valve: also known as gas emergency shut-off valve
imported gas solenoid valve is suitable for city gas, liquefied petroleum gas, natural gas and other gas-burning heating medium line to do two style-off switch for temperature control of the executive agency. It is widely used in the textile industry, printing industry, gas heat setting and glass, bulb industry and other industries furnace heating gas heating automatic control system.
imported gas solenoid valve, a gas pipeline safety emergency cut-off device. It can be connected with the gas leak or fire alarm systems and other intelligent alarm control terminal module connections, to achieve on-site or remote auto / manual emergency cut off gas supply to ensure gas safety. When harmful strong vibration, the valve will automatically close. Open valve shall be subject to human intervention, manual open, to meet the security management practices, consistent incident handling characteristics.
Explosion-proof solenoid valve performance in line with GB3836.1-2000, "Electrical apparatus for explosive gas atmospheres - Part 1: General requirements", GB3838.9-2006 "Electrical apparatus for explosive gas atmospheres - Part 9: Encapsulation" m "" provisions made Encapsulation structure, proof mark for Exmb | | T4, suitable for factory has | | A, | | B, | | C grade, T1 ~ T4 group explosive gas or vapor and air to form an explosive gas mixture Regions 1 and 2 areas.

Gas solenoid valve installation:
1 valve is installed units should have the appropriate qualifications and press the gas pipeline construction specifications related to installation.
2 valves should be installed indoors after the total intake valve for maintenance.
3 indicate the direction of airflow valve should be installed, the valve coils not inverted, allowing horizontal and vertical installation.
4 solenoid valve control lines should be correct and reliable connection, control line polarity: the white wire is the positive black line is negative, can not be reversed.
5 pipe purging, it is recommended to isolate the solenoid valve to prevent damage to the valve pipe sealing material debris.
6 pipeline pressure test detected during the sealing performance, before the solenoid valve at the open valve state.
7 manually open the valve when the valve outlet pressure should be in balance operation.
8 Electric Off valve, should not take the wrong power supply, such as: pick the wrong polarity, add the wrong voltage or long power so as to avoid damage to the solenoid coil.
