　　进口安全泄压持压阀产品详情 Productdetails

　　泄压持压阀、紧急开启阀在传动方式上采用了水力操作并能自动控制，即利用控制管路中的压差自动开合，关闭主阀，使上游的压力不超过某一设定值。阀体采用了全通道流线型设计，流体阻力小，密封性能好，自动启闭性能灵敏。该阀的主要特点是既可以作泄压阀，又可以作持压阀。

　　The imported pressure relief and emergencyopening valves adopt hydraulic operation and can be automatically controlled intransmission mode, that is, use the pressure difference in the control pipelineto automatically open and close, close the main valve, and ensure that theupstream pressure does not exceed a certain set value. The valve body adoptsthe full channel streamline design, with small fluid resistance, good sealingperformance, and sensitive automatic opening and closing performance. The mainfeature of this valve is that it can be used as both a pressure relief valveand a pressure holding valve.

　　进口安全泄压持压阀工作原理 Workingprinciple

　　1.作泄压阀时：可将水管中超过先导阀安全设定值的压力释放，并维持管中压力于一定安全值以下，以防止管中高压或突压毁坏管线设备

　　When using a pressure relief valve: it canrelease the pressure in the water pipe that exceeds the safety setting value ofthe pilot valve, and maintain the pressure in the pipe below a certain safetyvalue to prevent high pressure or sudden pressure in the pipe from damagingpipeline equipment

　　2.作持压阀时：可维持主阀上游供水压力于某一设定直以上，以保障主阀上游的供水压力

　　When acting as a pressure holding valve, itcan maintain the upstream water supply pressure of the main valve above acertain set point to ensure the upstream water supply pressure of the mainvalve

　　3.作紧急开启阀时：装于消防喷淋泵出水口处，当泵出水口处压力上升某一设定值以上立即开启

　　When acting as an emergency opening valve:installed at the outlet of the fire sprinkler pump, immediately open when thepressure at the pump outlet rises above a certain set value
