摘要： PROBLEM TO BE SOLVED: To provide a gas-blast circuit breaking device that can open a cutoff valve closed at the time of consumption of a battery, a power source of the gas-blast circuit breaking device, according to a specified rule. SOLUTION: Specified battery consumption voltage before reaching the lower limit value of battery consumption of a battery power source 10 is detected by a voltage drop detecting part 2, and a cutoff valve 9 is closed by a gas-blast circuit breaking control part 6, while the cutoff valve 9 can be opened when an opening receiving part 3 receives an opening demand. A timer part starts counting from the time of detecting the battery consumption voltage. After the lapse of preset specified time, opening action is stopped by an opening function stop part 5, and a gas passage is cut off again by the cutoff valve 9. With this action, gas is usable until a gas-blast circuit breaking device is replaced due to battery consumption.

摘要： PROBLEM TO BE SOLVED: To prolong the lifetime of a battery by providing a cock switching indicating unit for outputting the cock switching allowing signal, a cock switching signal generating unit for outputting the cock switching output signal and a switching cock driving unit for opening and closing a gas passage with a cock, and desirably setting the electrifying time for driving the switching cock in the cock switching signal generating unit. SOLUTION: A timer counter for showing the total used time of a device is counted by a cock switching indicating unit 1, and in the case where the indication for switching a cock is not given, the processing is concluded. In the case where the indication is given, a cock switching signal generating unit 2 judges whether a value of the timer counter achieves the predetermined value, for example, a half value of the used time as a lifetime of a device or a value at 80% of the lifetime of the product, at which voltage is suddenly lowered, or not. In case of a value less than the predetermined value, battery voltage is judged sufficient, and a short electrifying time is set. In the case of the predetermined value or more, lowering of battery voltage is judged, and a long electrifying time is set. A switching cock driving unit 3 opens and closes a gas passage with a double-way cut-off valve, and the working is concluded. Abrasion of a built-in battery can be thereby lowered.

摘要： PROBLEM TO BE SOLVED: To interrupt a gas passage by discriminating the leakage of gas from a gas consuming pattern and the abnormal use of a gas device for a long time. SOLUTION: The leakage of gas unstable in its flow rate which leaks from a rubber hose or the like and the abnormal use of a complicated control gas device for a long time are discriminated from a consuming pattern with many changes. When a flow rate signal from a flow rate measuring means 2 is located within a range of prescribed flow rate, it is measured what number of times of the ON/OFF signals of an individual equipment are generated from an individual equipment estimating means 3 for a prescribed period. When the number of times is a prescribed number or more, this pattern is discriminated from the consuming pattern of an ordinary gas equipment by a using pattern monitor means 6 for outputting a using pattern abnormal signal. Thus, in the case of an abnormal gas consuming pattern, a gas passage is interrupted.

摘要： PROBLEM TO BE SOLVED: To automatize opening of a valve by instructing the time, reconcile safety and convenience, and improve reliability of a gas interruption apparatus. SOLUTION: A valve opening time instruction signal B is outputted from a sensor monitoring part 1 through a communication receiver part 2, and a valve is opened with a valve opening/closing driving part 4 following a valve opening signal C when the time reaches a specific time set in association with the valve opening instruction time in a valve opening instruction part 3. Further, the existence of leakage is judged in a leakage detection part 6 based upon a flow rate signal of a flow rate detection part 5 whereby a gas use allowance signal or a gas use interruption signal is outputted. When the gas use interruption signal E is outputted, a valve closing instruction part 7 outputs a valve closing signal H and hence the valve opening/closing driving part 4 closes the valve.

摘要： PURPOSE: To enhance the reliability as a gas-blast circuit-breaking device by mutually monitoring whether a trouble occurs in a flow rate measuring means to detect an abnormality flow rate for gas and a pressure sensor to detect abnormality of a gas pressure. CONSTITUTION: A gas apparatus combustion means A detects whether gas is used in a spot situated downstream from a gas meter 4 from the increase and the decrease of a flow rate signal from a flow rate measuring means 1, and outputs an apparatus combustion signal A. Meanwhile, a gas apparatus combustion means B detects whether gas is used in a spot situated downstream from the gas meter 4 from the increase and the decrease of a pressure signal from a pressure sensor 8 and outputs an apparatus combustion signal B. A control part 11 announces non-coincidence to the outside through an announcing means 12 when an apparatus combustion signal A and an apparatus combustion signal B do not coincide with each other and improves reliability of a gas-blast circuit-breaking device.

摘要： PURPOSE: To reduce the consumption of a battery of a gas emergency trip device so as to increase the reliability of it by driving a valve drive part when a gas unuse signal from a flow monitoring means is present so as to close a shut-off valve and, after a specified time, turn off the power of each means for selecting a low power mode. CONSTITUTION: When a gas enterpriser inputs a gas unuse signal from an external input terminal 5, a control part 16 drives a valve drive part 3 when the gas unuse signal is present so as to close a shut-off valve 2 and, after 40sec later, turn off the powers of an external sensor input means 6, an alarm means 10, and a valve return means 7 for selecting low power mode. Even if the gas enterpriser fails to input the gas unuse signal, a signal from a flow monitoring means 8 outputs the gas unuse signal when gas flow is zero for two weeks. By this, not only the input operation from the external input terminal 5 of the gas enterpriser is reduced but also the battery 17 of the gas emergency trip device is suppressed from consuming when monitoring is never required. Thus the reliability of the emergency trip device is increased and the device is tripped surely so that the safety can be maintained even when a house is not dwelled.

摘要： PURPOSE: To enhance the reliability by simulating the operation at a pressure detecting section periodically. CONSTITUTION: When the gas pressure in a gas passage drops below a predetermined level, a pressure detecting section 2 delivers a pressure drop signal B. When the pressure drop signal B is not delivered, a gas pressure drop signal D is delivered forcibly and periodically from a section 5. If a flow rate signal A is received during delivery of the pressure drop signal B or the pressure drop signal B is not present during delivery of the forced pressure drop signal D, an interruption alarm signal C is delivered from a pressure decision section 3.

摘要： PURPOSE:To improve reliability by preventing erroneous stop from being generated again by re-registering the learnt result when the erroneous stop occurs after learning is completed. CONSTITUTION:A flow rate signal G from a flow rate measuring means 1 is calculated into a real flow rate P1 by a flow rate arithmetic part 2. During a prescribed learning term, a learning processing part 3 calculates a flow rate pattern Q as the learnt result and holds it. Further, a flow rate decision part 4 receives the flow rate pattern Q from the learning processing part and a flow rate pattern P2 from the flow rate arithmetic part and compares them and in the case of abnormality, a stop/alarm signal R is outputted. A stop alarming means 5 issues an alarm or stops a gas route. While receiving the signal of this flow rate decision part 4, a stop flow rate storage part 6 stores a flow rate pattern F at the time of stop. Corresponding to an input from the outside, a reregister signal T is outputted by an erroneous stop time reregister signal input means 7. An erroneous stop time reregister processing part 8 instructs the holding of the flow rate pattern F in the stop flow rate storage part 6 to the learning processing part 3 and updates the learnt result.
