    • Enabled is to detect the content volume and leakage amount of a pipeline to be inspected, simply and promptly with a remarkably small inspecting device so that the propriety of the inspection result of the pipeline may be precisely judged with the leakage amount related to the content volume of the pipeline. In a leakage inspecting method for a pipe line, an inspecting gas is fed at a predetermined flow rate inward from one end opening of the inspected pipe line in a closed state, while the flow rate being detected by a flow meter and the pressure being detected by a pressure detector, and the temperature of the pipe line or the inspecting gas fed to the pipe line is detected by a temperature detector. The detected pressure value, the detected flow rate value and the detected temperature value are inputted to a processor so that the content volume VL of the inspected pipe line is calculated as VL = Feed Flow Rate Q x Pressure Time Period t / Pressure Rise P2, from the pressure time period t till the pressure rise P2 in the inspected pipe line becomes a set value and from the feed flow rate Q of the inspecting gas. Next, the leakage amount QL from the inspected pipe line is calculated as QL = Pressure Drop P2' x Pipe Line Content Volume VL / Pressure Drop Time t', from the pressure drop P2' after lapse of the predetermined pressure drop time t' after the inside of the inspected pipeline was pressurized to a predetermined value, and from the pipeline content volume VL calculated.
    • 启用是检查管道的内容量和泄漏量,简单快速地检查设备,使得管道检查结果的合适性可以用与内容相关的泄漏量精确判断 的管道。 在管线的泄漏检查方法中,以关闭状态从被检查管路的一个端部开口向内侧以规定的流量供给检查气体,同时由流量计检测流量并检测压力 通过压力检测器,通过温度检测器检测供给到管路的管路或检查气体的温度。 将检测到的压力值,检测流量值和检测到的温度值输入到处理器,使得被检查管路的内容积VL被计算为VL =进料流量Q x压力时间段t /压力上升P2, 从加压时间t到检查管路中的压力上升P2成为设定值,并且从检查气体的供给流量Q开始。 接下来,从经过预定管线的泄漏量QL计算出经过预定压力下降时间t'之后的压降P2'的QL =压降P2'×管线内容量VL /压降时间t' 被检查管道的内部被加压到预定值,并且从管道内容物体积VL计算。

    • A coupling for a fluid control apparatus and a fluid control apparatus using the same are provided to remarkably lighten in comparison with a conventional coupling by employing light material to form the coupling. A coupling for a fluid control apparatus includes a connection member(23) and a channel member(24). The connection member has a groove at the center of the connection member. A device formation member is fixed by a male screw member for adhering the device formation part. The channel member has a channel path(12) and exists at the groove. The channel member is made of corrosion resistance substances. Specific gravity of the connection member is less than that of the channel member because the connection member is made of light specific gravity substances. A component member of the groove screw connected with the male screw member for adhering the device formation part is buried in the connection member. The component member of the groove and the channel member are made of stainless steel or stainless alloy. The connection member is made of aluminum.
