Description

  The present invention relates to a pressure regulating equipment. More specifically, the present invention relates to a small pressure regulator that can be easily inspected and maintained and can save space.

  At present, for example, city gas is sent to a city gas transportation line at a high pressure, and is supplied to consumers after being decompressed and regulated to a predetermined pressure by a gas pressure regulation facility provided in the transportation line. .

  In this case, most of the high-pressure gas pressure regulators that are currently in operation are more correct than the “equipment” for pressure regulation, and it is more correct to say that the pressure regulation “place”. It was manufactured separately, brought into the field, assembled on site, and a large building covering it was built to form a single pressure regulator.

  Therefore, in order to install one pressure regulating equipment, a very large installation area is required, and it is often difficult for a supplier to secure an installation location.

  In order to solve such a problem, the development which unitizes pressure regulation equipment is also performed now (for example, refer patent document 1).

According to the pressure regulating equipment disclosed in Patent Document 1, the installation area can be remarkably reduced as compared with a conventional pressure regulating station.

  Here, it is necessary to periodically inspect and maintain the gas pressure regulator from the safety and legal aspects. Therefore, it is necessary to secure a space necessary for workers to enter inside the gas pressure regulation equipment and to inspect and maintain various devices.

  Then, even in the pressure regulating equipment disclosed in Patent Document 1, a space for inspection / maintenance is ensured, and the size of the whole equipment is increased by that amount, so that complete downsizing can be achieved. I can't say that.

  In other words, in the field of gas pressure regulation equipment, it is necessary to always consider the space for inspection and maintenance, and the problem that the miniaturization of the entire apparatus does not proceed by that space was inherent. .

  The present invention is an invention made in such a situation, and a main object is to provide a pressure regulating equipment that can sufficiently perform inspection and maintenance and can realize space saving.

  As a result of diligent investigations to solve the above problems, the inventors of the present application overturned the conventional common sense that “a space for inspection and maintenance must be provided inside the facility” and “inspected and maintained internal devices from outside the facility”. The present invention has been conceived.

  That is, the present invention for solving the above-described problems is a pressure regulating equipment used for adjusting the pressure of gas from the upstream side and supplying it to the downstream side. And a storage box that can store the various devices. The storage box has doors on at least two surfaces thereof, and the various devices as necessary. When inspecting and servicing the various devices, without entering the storage box, by opening the door provided in the storage box, or by removing the storage box It can be inspected and maintained.

  In the above invention, the various devices necessary for pressure regulation, which constitute the pressure regulation equipment, include an emergency shutoff valve, a gas filter, a gas heating equipment, a governor, a shutoff valve, a pressure relief device, and these You may be comprised from the piping connected.

  Furthermore, in the said invention, the sound-insulation member may be installed in the inner wall face of the said storage box.

  According to the pressure regulating equipment of the present invention, it is a pressure regulating equipment used for adjusting the pressure of gas from the upstream side and supplying it to the downstream side, and the pressure regulating equipment includes various devices necessary for pressure regulation. And a storage box that can store the various devices, the storage box has a door on at least two surfaces, and is removable from the various devices as required. When inspecting and servicing the various devices, inspection and servicing can be performed by opening a door provided in the storage box or removing the storage box without entering a storage box. Therefore, it is possible to eliminate the space for inspection and maintenance from the inside of the pressure regulating equipment, and it is possible to reduce the size accordingly. As a result, it is not only easy for a consumer to prepare a space for pressure regulating equipment, but the pressure regulating equipment can be used simply by assembling it in the factory and installing it at the place of use. Convenient.

  In addition, various devices necessary for pressure regulation that constitute the pressure regulation equipment include an emergency shut-off valve, a gas filter, a gas heating equipment, a governor, a shut-off valve, a pressure relief device, and a pipe connecting them. By having these, the same function as the conventional pressure regulating equipment can be exhibited.

  Furthermore, by installing a soundproof member on the inner wall surface of the storage box, it is possible to eliminate the problem of noise that may occur when the storage box is downsized.

  Hereinafter, the pressure regulating equipment of the present invention will be specifically described with reference to the drawings.

  FIG. 1 is an external perspective view of the pressure regulating equipment 100 of the present invention.
