摘要： In a conventional relief valve having a valve element supported by a diaphragm, since a surface of the valve element exposed to pressure is large and an opening/closing operation of the valve element is rapidly conducted, the operation often leads to chattering and is therefore poor in stability. A relief valve of the invention is free from chattering and capable of smoothly performing the opening/closing operation of its valve element (7). The element (7) is adapted to open and close a fluid passage and disposed between: an inlet port (2) in direct communication with an upstream-side fluid passage (1); and, an outlet port (4) in direct communication with a downstream-side fluid passage (3), and is provided with a flange (8) in its upper portion. Mounted on the flange (8) is a sleeve-like bellows (6) for supporting the valve element (7).

摘要： A flow rate controller detects a clogged state of an orifice to prevent errors during flow rate measurement. The flow rate controller includes a differential pressure flow meter, with an orifice disposed between a pair of pressure sensors, that converts a pressure difference detected by the two pressure sensors into a flow rate, a flow-rate adjusting valve whose degree of opening is controlled such that the difference between a measured flow rate value and a preset flow rate value falls within a predetermined range, and a control unit that controls the degree of opening of the flow-rate adjusting valve upon receiving the pressure values detected by the pressure sensors. The control unit compares the preset flow rate value and the measured flow rate value and determines that there is a clog fault when a flow rate difference, as compared with a predetermined value, continues for a predetermined time period.
