Description

  The present invention relates to a piping facility inspection preparation apparatus and an inspection preparation method for preparing for construction defect inspection for piping facilities.

  Piping laid in facilities such as houses is often laid on the wall surface or under the floor to secure indoor space or aesthetics, and it is flexible to increase the degree of freedom of piping laying. In many cases, piping is used to form a bent piping path that bypasses an obstacle. In particular, the heat dissipating unit in the floor heating facility stretches a resin pipe bent under the floor and forms a circulation path of hot water by the resin pipe.

  Such a piping facility is inspected as to whether or not it is correctly constructed after being laid in the wall surface or under the floor. As this inspection, one is a leakage inspection, and the other is a nail driving inspection.

  Leakage inspection is to inspect the presence or absence of leaks in pipes. Filled pipes are filled with pressurized fluid (water) and inspected by detecting the presence or absence of pressure drop over time. .

  The nail driving inspection is to inspect whether or not a nail that is struck during construction of a wall surface or a floor surface is stuck in the pipe. If the pipe is nail-pierced, the hole is blocked by the nail-pierced nail, so the initial leak test often does not detect a pressure drop, and leakage may occur after the piping equipment is in operation. In addition to leak inspection, inspection with a nail detector is performed.

  The nailing detector used here is, for example, as shown in Patent Documents 1 and 2 below. The basic principle is that for insulating resin pipes, water that is a conductive material is filled in the pipe, the first conductive path is formed by the water in the pipe, and the pipe is provided on the surface of the pipe. A second conductive path is formed by the conductive coating, and it is electrically detected that the first conductive path and the second conductive path are short-circuited when the nail is stuck in the pipe.

Japanese Patent Laid-Open No. 11-287783 JP 2002-243688 A

  When performing the above-described leakage inspection and nailing inspection on the piping facility, first, the piping is cleaned, and then the preparatory work for filling the piping with water is performed. The important thing here is to completely eliminate the air trap in the pipe and fill the pipe with water, and if this is insufficient, the leak test will not give a highly accurate result. In addition, since the conductive path due to the water in the pipe is interrupted by the air reservoir, the inspection by the nail driving detector cannot be performed effectively.

  In contrast, normally, water is supplied from one end of a pipe with a manual or electric pump and water is discharged from the other end while the pipe is filled with water. It is difficult to constantly supply water that does not contain, and as described above, in recent piping circumstances, bent pipe paths are often formed, so that air is trapped at the peak of the bent pipe. Therefore, it takes a lot of time and labor to completely fill the pipe with water without air accumulation. In particular, when continuously inspecting piping facilities laid in an apartment house, preparation work requires a great deal of time and labor.

  Further, in the above-described method, a large amount of water is supplied from one end to the pipe and discharged from the other end, so that there is a problem in that the periphery of the pipe laying location gets wet with water. In particular, since inspection of such piping equipment is often performed before delivery of a new house, there is a demand for minimizing water wetting around the periphery.

  On the other hand, it is possible to reduce time and labor by using an electric pump, but the above-mentioned problem of water wetting is not solved by this, and in the situation such as before delivery of a new house, it is necessary to operate the pump. There is also a problem that it is difficult to secure a power source.

  The present invention has been proposed in order to cope with such a situation, and when preparing for construction defect inspection for piping equipment, the air reservoir in the piping is surely removed to fill the piping with water. Reducing the time and labor of this preparatory work, being able to perform smooth preparatory work without getting wet around the piping to be inspected, and being able to easily work even in places where it is difficult to secure power It is an object of the present invention.

  In order to achieve such an object, the piping equipment inspection preparation device and inspection preparation method of the present invention have the following features.

  Furthermore, in the piping facility inspection preparation method for filling the piping with water with respect to the piping facility to be inspected, the water stored in the portable container is passed through the water supply path by a battery-driven pressurizing pump. Supplying water to one end of the pipe and recovering the water drained from the other end of the pipe into the portable container via a drainage path, and collecting the water stored in the portable container to the pipe It is characterized in that the pipe is filled with water in a state where there is no air accumulation in the pipe.

  In the pipe facility inspection preparation method, a filter is provided in the upstream water supply path of the pressurizing pump, and the pipes are simultaneously cleaned by the process.

  In the pipe facility inspection preparation method, a pressure gauge is provided in a downstream supply path of the pressurizing pump, and the supply path and the pressure line are filled with pressurized water having a set pressure necessary for leak inspection. A connection end between the drainage path and the pipe is cut off.

  According to the piping equipment inspection preparation apparatus and inspection preparation method having such characteristics, the following operations can be obtained.

  That is, at the inspection work site for piping equipment, water is stored in a portable container, and the air pool in the piping is removed in the process of circulating this water in the piping, so that a predetermined pressure required for inspection in the piping is removed. Fill with water. In order to confirm that the air pocket has been completely removed, if the drainage end of the drainage path is placed in the water in the transportable container, bubbles are not generated from the drainage end, so that the air pocket is completely removed. It can be confirmed that it has been eliminated.

  Since a certain amount of water in the portable container is used and the water supplied to the pipe is collected in the portable container, the area around the pipe to be inspected is not wetted with water and is stored. Since water is circulated by a pressurizing pump, it is possible to supply water that is less likely to generate stable bubbles. As a result, it is possible to eliminate air accumulation in a short time and to fill the pipe with water of a predetermined pressure, and to reduce the work effort.

  In addition, since the pressure pump is driven by a battery using a portable container, it is easy to carry the device into the work site and to move to the work site, and to work without any problem even at a work site without a drive power supply. Can do.

  Furthermore, by providing a relief valve and a pressure gauge in the downstream water supply path of the pressurization pump, the supply pressure is adjusted by the relief valve while eliminating the air trap mentioned above, and the pressure state is confirmed by the pressure gauge. It is possible to set the filling pressure necessary for the leak inspection simultaneously with the removal of the air reservoir.

  Further, by providing a filter for collecting dirt on the pipe upstream of the pressurizing pump, the pipe can be cleaned simultaneously with the water filling process described above.

  Furthermore, a pressurizing pump unit in which a pressurizing pump, a relief valve, a pressure gauge, a filter, etc. are unitized, and a battery unit for driving the pressurizing pump to a battery are provided, and these are provided above the portable container when not in use. By enabling storage from the opening, the apparatus can be easily carried into the work site and the apparatus can be moved after the work, and workability can be improved.

  As described above, according to the present invention, when preparing for a construction defect inspection for piping equipment, it is possible to reliably eliminate air accumulation in the piping and fill the piping with water of a predetermined pressure. Moreover, the time and labor of this preparatory work can be reduced. In addition, smooth preparatory work can be performed without getting wet around the piping to be inspected. Furthermore, the work can be performed without problems even in a place where it is difficult to secure a power source.

  FIG. 1 is an explanatory diagram showing a system configuration of a piping equipment inspection preparation apparatus according to an embodiment of the present invention. This piping equipment inspection preparation device 2 fills the piping equipment 1 with water in the piping 1A as preparation work for leakage inspection and nailing inspection.

Since the hose constituting the water supply path 20A and the hose constituting the drainage path 20B need to completely immerse the water inlet end and the water drain end in the water stored in the portable container 26, the length of the hose A surplus length portion is formed, and the surplus length portion is arranged so as to wrap around the bottom of the portable container 26. Moreover, you may make it attach the lid | cover which formed the hole which a hose passes in the upper opening of the portable container 26 as needed so that this hose may not remove | deviate from the portable container 26. FIG.

  The pressure pump 24 is driven by a battery 27. The battery 27 is charged by an attached charger, and can be connected to an AC power source via an AC / DC converter as necessary.

  The pressure gauge 22 and the relief valve 23 described above are provided on the downstream side of the pressurizing pump 24, and the filter 25 described above is provided on the upstream side of the pressurizing pump 24. The filter 25 has a function of collecting dirt in the pipe 1A.

  Moreover, such a piping equipment inspection preparation device 2 can improve the portability when not in use by unitizing each part.
