供应美国tyco泰科流体控制ZSFM系列隔膜雨淋阀

美国tyco泰科流体控制ZSFM系列隔膜雨淋阀由主阀，水力警铃，压力开关，手动球阀，电磁阀，三通球阀，针阀及控制管路等组成。配以开式喷头、水幕喷头、闭式喷头及火灾报警控制系统即可组成相应的水喷雾灭火系统。具有结构简单、操作容易、安全**、安装维护方便等特点。失火时，雨淋阀开启，系统开式喷头一齐自动喷水灭火，不仅可以灭火处火源，而且可以同时自动向整个被保护的面积上喷水，从而防止火灾的蔓延和扩大。适用于易结冰或需**保护的火灾危险性大的建筑物和场地。
ZSFM series diaphragm raining valve consists of main valve, hydraulic warn-bell, pressure switch, manual ball valve, solenoid valve, three-way ball valve, needle valve and control pipeline and, equipped with an opened shower, water curtain shower, closed shower and fire warning control system, can form the corresponding water sprayed fog fire extinguishing system, It features a simple structure, easy, safe and reliable operation, convenient installation and maintenance In case of a fire, the valve is opened, together with the opened shower, to automatically spray water to extinguish it, not only turning off the fire source but also automatically spraying water onto the whole protected area so as to prevent the fire from extending, Suitable for the building and playground easy to iced or required to be seriously proteeted and of a big fire danger.

结构及用途STRUCTURE AND PURPOSE
  ZSFM系列隔膜雨淋阀主阀采用隔膜将主阀分为上下两腔，上腔为控制腔。利用上下腔面积差产生水压力实现主阀密封。未失火时，三通球阀手柄向下，针阀、检修球阀、末端球阀为开启状态，电磁阀、手动球阀、排放球阀为开闭状态，压力表1灰进口压力，压力表2为0. 此时主阀为关闭状态。失火时，有三种控制方式控制主阀开启灭火。主阀开启后，压力进入压力开关盒水力警铃，水力警铃发出警声；压力开关向控制中心发出信号或开启消防泵。隔膜雨淋阀具有防复位结构，主阀开启10﹪后防复位装置自动启动，防止由于误操作使主阀回位。灭火后，切断传动管网，关闭电磁阀。、手动球阀和末端球阀即可关闭主阀。 
结构合理、美观：雨淋阀控制管线选用**铜管，合理配置控制元件，使控制阀门简单，明了。 
控制、操作方便、**：三种控制方式确保主阀开启，且三种控制方式中任一种控制方式均能开启主阀。 
内置 防复位装置：防复位装置内简化了控制配管。防复位装置的启动由主阀自动控制，复位操作简单。 
The main valve of ZSFM series diaphragm raining valve divides itself into upper and lower two cavities, the upper one is the control cavity, and utilizes/the are difference between the cavities to produce water pressure to realize sealing of it, when there is no fire, the tee ball valve’s handle is downward ,the needle valve, overhaul ball valve are opened, the solenoid valve, manual ball valve and drainage ball valve are closed, the pressure gauge 1 shows the inlet pressure and the pressure gauge 2 shows zero. The main valve is closed then, There are three control modes, in case of a fire, to control the main valve to be opened to put out the fire ,After the main valve is opened, pressure steps into both pressure switch and hydraulic warn-bell, the latter sends out a warning sound and the former sends out a ** to the control center or to open the fire-fighting pump, This valve is of a reset resisting structure, which automatically opens after the main valve is opened by 10﹪to prevent it from reset due to wrong operation, After the fire is put, the main valve can be closed just by cutting off the driving pipe network, closing the solenoid valve, manual ball and final-end valve.
