双向、自动空压力表阀门它不受方向的限制,可以安装在任何不同方向设计的工艺管线和设备上。在安装时不必选择相应的阀门的安装方向,在拆卸压力表操作时,当关闭压力表的控制阀门,压力表的放空阀自动打开放净压力表内的余压。无需再打开压力表的放空开关,保证了操作人员的安全。在采购上、制造上都非常方便,降低了制造成本和工作人员的劳动强度,提高了安全系数,节约采购成本,提高了经济效益。
Two-way, automatic air pressure gauge valve It is not subject to the direction of restrictions, can be installed in any direction of the design process piping and equipment. In the installation do not have to choose the appropriate valve installation direction, when you remove the pressure gauge operation, when you close the control valve of the pressure gauge, pressure gauge vent valve automatically open to put the net pressure gauge residual pressure. No need to open the pressure gauge vent switch to ensure the safety of the operator. In the procurement, the manufacture is very convenient, reducing manufacturing costs and staff labor intensity, increased safety factor, saving procurement costs and improve economic efficiency.
