摘要： PURPOSE:To realize a pressure control device capable of quickening a response and properly controlling in accordance with pressure state. CONSTITUTION:The error between detection data D2 of a pressure detector provided in the vicinity of a piping nozzle and a preliminarily set setting value Ds is amplified by a differential amplifier 5. The amplified value is integrated by an integration circuit 6 and controls a pressure regulator, and a time constant switching circuit 10 controls an analog switch 8 based on the output value of the differential amplifier circuit 5 and switches the time constant of the integration circuit 6. Therefore, a control response can be changed in accordance with the state of the detection data D2 and an optimum control always becomes possible.

摘要： PURPOSE:To check gas-leak from both first shut-off valve and the second shut- off valve in a short time by judging that there is no abnormality such as leak from both shut-off valves when pressure in a chamber does not reduce to the second pressure value higher than the first pressure value within a time shorter than a predetermined time, after setting the pressure in the chamber between the first shut-off valve and the second one to a predetermined value. CONSTITUTION:A method for checking leak from double shut-off gas valves 1, 2 is such that after pressure in detection objective chamber is set at a predetermined pressure valve, when the pressure value does not reduce to the second set pressure value within a time shorter than a predetermined time, it is judged that there is no abnormality such as valve leak. In a leak checker for double shut-off gas valves, after pressure in the detection objective member 11 is set at a predetermined pressure valve, a controller 10 for judging that the pressure does not reduce to the second pressure value within a time shorter than a predetermined time judges no abnormality such as valve leak. Thus, a time for checking valve leak is remarkably shortened.

摘要： PURPOSE: To conduct a reliable sequence function of a pressure displacing and converting mechanism, by a method wherein two systems are formed in a parallel relation to each other at the discharge side of a hydraulic pump, and orifices, being different in a diameter from each other, are located to their respective systems to select either of the two systems with the aid of an electromagnetic valve.
CONSTITUTION: Working fluid discharged to a system 10 side from a hydraulic pump 2 returns to an oil tank 1 through a system 11 when an electromagnetic valve 5 is opened and through systems 12 and 13 when an electromagnetic valve 6 is opened. A diameter of an orifice 7 in the system 11 is larger than that of an orifice 8 in the system 13, and in the systems 11 and 12, a pressure P1 is generated when the valve 5 is opened, and a pressure P2, being higher than P1, is produced when the valve 6 is opened. A pressure displacing and converting mechanism 3 is actuated by means of the P1 and a mechanism 4 by means of the P2. With either of the valves 5 and 6 opened, an oil pressure at a discharge side is switched to perform a reliable sequence function of the mechanisms 3 and 4.

摘要： PURPOSE:To simplify a mechanism driving a plurality of valve actuators by changing over a hydraulic pressure applied to the valve actuators with a sequence valve provided at a path by-passing a suction and a delivery of an electromagnetic pump. CONSTITUTION:The electromagnetic pump 14 sucks oil in an oil tank 17 via the path 16 and returns the oil to the tank 17 from the path 18. Since an orifice 19 is provided in the path 18, a prescribed pressure is generated between the pump 14 and the orifice 19, and this pressure displaces three followers 21, 22 and 23 of the three valve actuators via the path 20. Thus, valves 7, 12, 8 and 10 are respectively driven. The sequence value 15 is provided at the path connecting the suction and the delivery of the pump 14, and when the valve 15 is opened, the pressure in the path 20 is suppressed to a low value determined with the opening area.

摘要： PURPOSE:To easily cope with the change of gas types and the change of the maximum guantity by changing the relative angle between a valve tube and an adjusting tube so as to change the relation between the amount of movement of a valve plug and the gas flow. CONSTITUTION:When a driving current is applied to the coil 11 of an electromagnetic pump 13, the temperature in pressure chambers 17, 20 is increased and an opening/closing valve and a proportional valve 50 are opened. If the angle of an adjusting tube 53 in relation to a valve tube 52 is the same, gas flows through an outlet passage 43 in response to the displacement of the proportional valve 50. When a transfer valve is operated to rotate the adjusting tube 53 by a predetermined angle, the positional relationship between a gap 57 and a window 60 is changed, then the relation between the amount of movement of the proportional valve 50 and the gas flow through the outlet passage 43 is also changed.

摘要： PURPOSE:To stably measure flow rates from a low flow rate to a high flow rate by arranging plural straightening wire nets in a flow passage at intervals, contracting the flow passage behind the wire nets, and arranging a microflow sensor right behind the contraction of area. CONSTITUTION:The straightening wire nets 71 - 74 are arranged in an entrance- side circular tube part 2 at the specific intervals, the flow passage right behind those wire nets 71 - 74 is formed into the area contraction part 3 where the flow passage is reduced in area, and the microflow sensor 11 is arranged right behind the contraction part 3. The straightening wire nets 71 - 74 may have relatively large meshes, so clogging due to dust in a flow and a pressure drop are small and disturbance and drift are reduced. Therefore, the disturbance of the flow becomes small at the microflow sensor 11. Consequently, stable measurement is stably performed from a low flow rate to a high flow rate.
