Description

The present invention relates to, for example, a pipe maintenance support device and a pipe maintenance support system that make it possible to visually recognize the presence of water leaks in existing pipes.

In areas where there are many earthquakes, even if it is a relatively small tremor, repeated tremors damage the building and its piping equipment, and water leaks continue without the residents noticing, which is a great cost. There are many cases of spending.
In recent years, where the existence of abandoned rooms and buildings such as vacant rooms in apartments or condominiums or vacant houses and old private houses has become a problem, accurately grasp the state of piping for those properties that are not in use. It is extremely difficult to do, and failure to do so can result in damage to the house due to water leaks and wasted expense.

Conventionally, various methods for measuring the water pressure of pipes have been introduced (see, for example, the following patent documents), but in these, a circuit for applying a constant water pressure to the pipe immediately after completion is provided, and water for inspection is introduced to control the water pressure. It is a method of measuring (see Patent Documents 1 to 3 below), or a method of measuring the hydrodynamic pressure by attaching an instrument to the faucet side of the faucet.

However, the former cannot measure the practical hydrostatic pressure of the existing piping, and the latter cannot accurately measure the hydrostatic pressure due to the presence of the check valve of the water stopcock, etc., and both are left unattended. There is a problem that it cannot be used for maintenance of building resources.

The present invention has been made in view of the above circumstances, and by appropriately inspecting water leakage even during use or dormant time, water leakage from pipes can be detected at an early stage, and a building can be comfortably maintained for a long time without accident. The purpose is to provide piping maintenance support equipment and piping maintenance support system for use.

The pipe maintenance support device according to the present invention, which has been made to solve the above problems, is interposed between a pressure gauge for measuring the pressure of the fluid flowing through the supply pipe and the supply pipe for the purpose of supplying the fluid, and of the supply pipe. A liquid guide tube that branches the flow path into a liquid feed path that is the target path of the supply pipe and a pressure detection path that sends fluid to the pressure gauge, and a liquid transfer path of the liquid guide tube are opened and closed to secure the pressure detection path. It is characterized by being provided with a fluid diversion device.
The destination path is a flow path that fulfills the original purpose of the supply pipe.
The pipe maintenance support device may also have a configuration including a switch for opening and closing the fluid pressure detection path.

The pipe maintenance support system according to the present invention, which has been made to solve the above problems, is characterized in that the liquid guide pipe of any of the above pipe maintenance support devices is connected to the supply pipe.

According to the piping maintenance support device and the piping maintenance support system according to the present invention, for example, inspecting water leakage of water supply equipment due to aging of a building or failure due to an earthquake, as in the conventional case, exclusively at the time of completion and repair. It is no longer performed only at times and not at other times, and water leakage inspection can be easily performed even during use or at rest.
This makes it possible to detect water leaks from pipes at an early stage, repair them at an early stage, and use valuable building resources with good quality for a long time without accidents.
