Description

Technical Field

[0001] The utility model relates to the technical field of gas transportation equipment, in particular to a gas pressure regulating box installation device. Background Art

[0002] At present, civil gas pressure regulating boxes generally install manual flange devices on medium-pressure pipelines, so that when gas leaks from the gas pressure regulating box, the medium-pressure pipeline can be disconnected through the flange device to prevent further gas leakage. However, the manual flange device can only disconnect the medium-pressure pipeline when personnel discover gas leakage. If no one discovers it for a long time, it will cause a major safety accident.

[0003] To this end, the prior art has realized automatic monitoring of gas leaks and timely closing of the pipeline by installing a solenoid valve on the medium-pressure air intake pipeline and installing a combustible detector connected to the solenoid valve in the pressure regulating box; at the same time, the current suspended gas pressure regulating box is generally suspended on the wall by expansion screws or installed on a mounting bracket and fixed to the wall by the mounting bracket. However, since the solenoid valve structure is added to the medium-pressure air intake pipeline, the use of the above-mentioned gas pressure regulating box installation structure will cause the solenoid valve to be exposed to the external environment for a long time, which will inevitably cause the solenoid valve to have a shorter service life or higher failure rate due to environmental influences; at the same time, after adding the solenoid valve structure, it is necessary to add another section of pipeline to the medium-pressure air intake pipeline, and the lack of protection or fixed structure between multiple sections of pipelines will also cause gas leakage problems at the pipeline connection, especially at the interface between the pipeline and the solenoid valve.

[0004] Therefore, it is necessary to improve the installation structure of the gas pressure regulating box to solve the above-mentioned problems. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present application provides a gas pressure regulating box installation device, which installs and supports the gas pressure regulating box by improving the conventional installation bracket under the gas pressure regulating box into a box structure, and can also protect the solenoid valve arranged on the gas medium-pressure air inlet pipe and located between the gas pressure regulating box and the manual flange ball valve. At the same time, the installation box can also limit the installation of the upper and lower pipes used to connect the solenoid valve and protect the interface with the solenoid valve.

[0006] The utility model provides a gas pressure regulating box installation device, including an installation box body arranged on a gas pipeline and located below the gas pressure regulating box, the installation box body has an accommodating cavity inside and the solenoid valve arranged on the gas medium-pressure pipeline is located in the accommodating cavity, the upper box plate and the lower box plate of the installation box body are respectively provided with through holes for the gas pipeline to pass through, and the through holes on the upper box plate and the through holes on the lower box plate are arranged correspondingly in the vertical direction.

[0007] Furthermore, the upper box plate is provided with a mounting hole for mounting the gas pressure regulating box and the gas pressure regulating box is mounted at the mounting hole by bolts. A limiting portion is also provided on the upper surface of the upper box plate and is used to limit the installation of the gas pressure regulating box.

[0008] Furthermore, the installation box is provided with connection holes on a rear box plate connected to the wall and is installed on the wall at the connection holes through expansion bolts.

[0009] Furthermore, the installation box body is provided with a front box plate on the opposite side of the rear box plate, and the upper end of the front box plate in the vertical direction is hinged to the upper box plate to realize the opening and closing of the accommodating cavity.

[0010] Furthermore, the installation box is also provided with transparent viewing windows for observing the accommodating cavity on the left box plate and the right box plate.

[0011] In summary, the present application includes at least one of the following beneficial effects: the gas pressure regulating box installation device of the utility model installs and supports the gas pressure regulating box by improving the conventional mounting bracket into a box structure under the gas pressure regulating box, and can also protect the solenoid valve arranged on the gas medium-pressure air intake pipe and located between the gas pressure regulating box and the manual flange ball valve. At the same time, the installation box can also install and limit the upper and lower pipes used to connect the solenoid valve and protect the interface with the solenoid valve.
