你好！1.有吊顶的，用吊顶型喷头，设在吊顶下；2.无吊顶的，溅水盘距离屋顶板下底0.075m~0.55m，视距离梁的水平距离决定。3.>0.8m的有可燃物的吊顶内须增设一排喷头，一般用上下喷。希望能帮到你

易熔合金消防喷淋头安装规范：安装时将喷头螺纹旋入外罩内，然后一起拧入安装管内，并用专用扳手伸入外罩内将喷头拧紧在管道上。拧紧时注意不要碰喷头的玻璃球及反溅盘；更不能扳拧喷头的支撑臂，否则会使喷头变形而发生泄漏。最后，将内罩旋入外罩内（应特别注意：因为内罩与底盖之间是用低温易熔合金焊接而成的，低温易熔合金的焊接强度较低，所以在旋入的时候应特别小心，不要在底盖上用力过大，应按内罩上的几个按螺旋分布的点慢慢旋入外罩内。若用力过大，将造成易熔合金断裂，底盖与内罩脱落。安装时应使用本厂生产的专用扳手。如果喷头安装后不能密封，绝不允许在扳手上用加长套管安装。应检查管件是否合格），若管件不合格，请更换或修复管件螺纹以后再行安装，若强行安装可能造成喷头损坏。

你好很高兴为你解答，消防喷淋头用于消防喷淋系统，当发生火灾时，水通过喷淋头溅水盘洒出进行灭火。消防喷淋头类型消防喷淋头一共有四种：分别为下垂型洒水喷头、直立型洒水喷头、普通新洒水喷头、边墙型洒水喷头;一、下垂型喷头是使用最广泛的一种喷头，下垂安装于供水支管上，洒水的形状为抛物体型，将总水量的80～100%喷向地面。主要用于不需要装饰的场所，如车间、仓库、停车库、厨房等。二、直立型喷头直立安装在供水支管上，洒水形状为抛物体型，将总水量的80～100%向下喷洒，同时还有一部分喷向吊顶，适宜安装在移动物较多，易发生撞击的场所如仓库，还可以暗装在房间吊顶夹层中的屋顶处以保护易燃物较多的吊顶顶硼。三、普通型洒水喷头既可直接安装，又可下垂安装于*管网上，将总水量的40%-60%向下喷洒，较大部分喷向吊顶。适用于餐厅、商店、仓库、地下车库等场所。四、边墙型洒水喷头靠墙安装，适宜于空间布管较难的场所安装，主要用于办公室、门厅、休息室、走廊客房等建筑物的轻危险部位。消防喷淋头安装间距1.喷淋头安装间距一般为直径3.6米，半径1.8米;2.喷淋头最大保护面积为12.5平方;3.喷淋头距墙不能小于300mm;4.当喷淋头与吊顶距离大于80m，且吊顶内有可燃物时需使用上下喷;消防喷淋头工作原理：消防喷淋头上的红色液体是一种对热极其敏感的东西。当温度升高，他就迅速膨胀，使装他的玻璃破裂，然后玻璃内的压力传感器就会使消防*泵*。希望我的回答能帮助你。望采纳。
