电热水锅炉安全阀有哪些安装要求?

1、电热水锅炉额定蒸发量大于0.5t/h的至少装设两个安全阀,额定蒸发量小于或等于0.5t/h的至少装一个安全阀。安全阀应垂直安装在锅炉锅筒、集箱的最高位置。在安全阀和锅筒或集箱之间,不得装有取用蒸汽的出口管和阀门。
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、电热水锅炉http://www.jnshengxin.cn/杠杆式安全阀要有防止重锤自行移动的装置和限制杠杆越轨的导架,弹簧式安全阀要有提升手把和防止随便拧动调整螺钉的装置。安全阀与锅炉的连接管,其截面积应不小于安全阀的进口截面积。如果几个安全阀共同装设在一根与锅筒直接相连的短管上,短管的通路截面积应不小于所有安全阀排汽面积的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、电热水锅炉http://www.jnshengxin.cn/安全阀一般应装设排汽管,排汽管应直通安全地点,并有足够的截面积,保证排汽畅通。安全阀排气管底部应装有接到安全地点的疏水管,在排气管和疏水管上都不允许装设阀门。
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.
