摘要： PROBLEM TO BE SOLVED: To make an air tight examining work for gas piping easy, by calculating the difference between the initial value of the gas pressure from a pressure chamber and the final value after the passage of a specific time, and determining the existence of the gas leakage on the basis of the result of the same. SOLUTION: A device comprises an element 6 having a pressure chamber 17, a digital manometer 11 having a semiconductor pressure sensor 26, and a three-way cock 2 having channels 10, 3, 5, 8. In the case when a new piping to which the gas has not been supplied, is examined, the pressed air of the specific pressure is included in the gas piping 1 to be examined, by a pump for pressurization 4. Then the three-way cock 2 is switched to make the pressed air in the gas piping 1 to be examine, act on the semiconductor pressure sensor 26. The digital manometer 11 stores this initial value, and the pressure of the pressed air after the passage of a specific time as the final value, calculates the difference between the initial value and the final value, and determines that the leakage does not exist when the difference between the final value and the initial value is within an extent of an allowable negative prescribed value, and the leakage exists when the difference is the negative value more than the prescribed value.

摘要： PURPOSE: To arrange two mortar receiver flanges in their respective territories by fastening and fixing both side elastic holding pieces between a pair of collar half bodies on a piping by way of sandwiching the piping. CONSTITUTION: It is constituted so that inner peripheral parts 21a, 21b of flanges 20a, 20b and internal surfaces of installation pieces 30a, 30b come along a piping outer peripheral surface, elasticity restraining pieces 31a, 31b projectively provided on their respective internal sides respectively make close contact with the outer peripheral surface of a piping 3. Thereafter, connected holding pieces 40a, 40b fasten the piping 3 by elasticity recovering force, and accordingly, slipping of a receiver jig consisting of a pair of collar half bodies is prevented. Consequently, it is possible to seal a lower side of a ring cavity between a through hole inner peripheral surface of a floor slab passing through the piping and the piping outer peripheral surface by both of the flanges of both of the collar half bodies.

摘要： PROBLEM TO BE SOLVED: To enable confirmation of support strength of a piping, by fitting with the use of a simple attachment means a quake-sensitive sensor to an object to be supported, e.g. a gas meter or the like supported by the piping, receiving a signal from the quake-sensitive sensor and detecting whether or not vibrations applied to the piping exceed a predetermined criterion. SOLUTION: When a sensor unit 1 is to be used, a male connector 15 at one end of a signal line is connected to a female connector 28 of an apparatus case 2. In consequence of the connection, a second quake-sensitive sensor 21 in the case 2 is disconnected automatically from a vibration-detecting means, while a first quake-sensitive sensor 11 of the sensor unit 1 is automatically connected to the vibration-detecting means. Thereafter, the sensor unit 1 is set to a gas meter which is an object supported by a piping. In order to set the sensor unit, a sucker 13b at a rear face of a horizontal plate part 2b is used to suck and hold the sensor unit in a horizontal state to an upper face of the gas meter. A power source switch 24 of the case 2 is turned ON, thereby applying various vibrations to the piping. The vibrations are detected by the quake-sensitive sensor 11 and input to the quake-detecting means in the case 2.
