1、電熱水鍋爐額定蒸發量大于0.5t/h的至少裝設兩個安全閥，額定蒸發量小于或等于0.5t/h的至少裝一個安全閥。安全閥應垂直安裝在鍋爐鍋筒、集箱的最高位置。在安全閥和鍋筒或集箱之間，不得裝有取用蒸汽的出口管和閥門。
Electric water boiler rated evaporation to 0.5t / h for at least two safety valves installed rated capacity of less than or equal to evaporation 0.5t / h to at least install a safety valve. Safety valve should be installed vertically in the highest position the boiler drum, set box. Between the valve and the drum or header shall be equipped with access steam outlet pipe and valves.

2、電熱水鍋爐http://www.shijilu.cn/杠桿式安全閥要有防止重錘自行移動的裝置和限制杠桿越軌的導架，彈簧式安全閥要有提升手把和防止隨便擰動調整螺釘的裝置。安全閥與鍋爐的連接管，其截面積應不小于安全閥的進口截面積。如果幾個安全閥共同裝設在一根與鍋筒直接相連的短管上，短管的通路截面積應不小于所有安全閥排汽面積的1.25倍。
Electric hot water boiler safety valve must be leveraged to prevent hammer their own mobile devices and limit leverage deviant guides, spring safety valve should enhance handle and prevent casual twist adjustment screw devices. Boiler safety valve and connecting pipe, its cross-sectional area of not less than the cross-sectional area of the valve imported. If several valves installed together on a short tube directly connected with the drum, short tube channel cross-sectional area of not less than all of the exhaust valve area of 1.25 times.

3、電熱水鍋爐http://www.shijilu.cn/安全閥一般應裝設排汽管，排汽管應直通安全地點，并有足夠的截面積，保證排汽暢通。安全閥排氣管底部應裝有接到安全地點的疏水管，在排氣管和疏水管上都不允許裝設閥門。
General electric water boiler safety valve should be installed in the exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area, to ensure the smooth flow of the exhaust. Safety valve should be fitted with an exhaust pipe at the bottom of the drainage pipe connected to a safe place, in the exhaust pipe and the installation of drainage pipe valves are not allowed.
