Description

A high-protection gas metering and pressure regulating cabinet Technical Field

[0001] This utility model relates to the field of pressure regulating cabinet technology, specifically to a high-protection gas metering pressure regulating cabinet. Background Technology

[0002] The high-protection gas metering and pressure regulating cabinet is an outdoor gas equipment that integrates gas metering, pressure regulation, and safety control functions. It is specially designed for high-risk environments or severe weather conditions. The cabinet is equipped with a high-precision gas flow meter that can monitor the gas flow in real time. It can also stabilize the upstream high-pressure gas to the user's required pressure through a multi-stage pressure regulating device. It has functions such as under-pressure protection and leakage alarm to ensure safety.

[0003] If the pressure regulating cabinet stops working when maintenance or shutdown is required, the internal equipment of the pressure regulating cabinet will stop heating due to the equipment's pause, causing the temperature inside the cabinet to drop. In cold regions or at cold temperatures, there is no heat source to maintain the temperature inside the cabinet during shutdown, which may lead to freezing of valves, instruments, or pipelines.

[0004] When the machine is shut down, insulation cotton needs to be installed on the outer or inner wall of the voltage regulator cabinet to protect the equipment inside the cabinet from damage due to low temperature in cold weather. When the temperature rises or when the machine is turned on, the insulation cotton needs to be removed to ensure heat dissipation inside the voltage regulator cabinet. Installing and removing the insulation cotton repeatedly is quite troublesome. Summary of the Invention

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 6. A high-protection gas metering and pressure regulating cabinet includes a pressure regulating cabinet body 1. A cabinet door with a handle is hinged to the side of the pressure regulating cabinet body 1. It also includes an insulation frame 2, mounting components, and an insulation board 3. The insulation frame 2 is U-shaped and is mounted on the pressure regulating cabinet body 1 via a moving component. The moving component is used to bring the insulation frame 2 into contact with or away from the pressure regulating cabinet body 1. The insulation frame 2 insulates three sides of the pressure regulating cabinet body 1. Several mounting components are provided, all of which are located on the side of the insulation frame 2. The insulation board 3 is mounted on the mounting components and is used to install the insulation board 3 on the side of the pressure regulating cabinet body 1. The side of the insulation board 3 has two through slots for the handles that pass through the cabinet door.

[0029] As shown in Figures 2, 3, and 6, in cold weather and when the pressure regulating cabinet needs to be shut down, in order to ensure that its internal equipment is not frozen, the moving component can first move the insulation rack 2 forward to fit against the outer wall of the pressure regulating cabinet. The moving component includes mounting plate 1 4, screw 5, moving block 6, connecting component, and synchronization component. Two mounting plates 1 4 are fixedly installed on the side of the pressure regulating cabinet body 1. The screw 5 is rotatably installed between the two mounting plates 1 4. The moving block 6 is installed on the screw 5. The connecting component is set on the insulation rack 2. The synchronization component is set on the side of the pressure regulating cabinet body 1. The synchronization component includes mounting plate 2 7, sliding rod 8, and sliding block 9. Two mounting plates 2 7 are fixedly installed on the other side of the pressure regulating cabinet body 1. The sliding rod 8 is fixedly installed between the two mounting plates 2 7. The sliding block 9 is slidably installed on the sliding rod 8. The connecting component includes connecting block 10 and connecting frame 11. Two connecting blocks 10 are fixedly installed at the bottom of the insulation rack 2. The two connecting blocks 10 are fixedly connected to the moving block 6 and the sliding block 9 through the connecting frame 11, respectively.

[0030] Specifically, it should be added that the screw 5 is coaxially connected to a throttle handle. By rotating the throttle handle, the screw 5 rotates between the two mounting plates 4. It should also be added that the moving block 6 has a threaded hole inside that matches the outer thread of the screw 5, so the moving block 6 can move back and forth on the screw 5. Driven by the connecting block 10 and the connecting frame 11, it drives the insulation rack 2 to move forward. On the other side, the sliding block 9 moves synchronously on the sliding rod 8 through the connection of the connecting block 10 and the connecting frame 11. The insulation rack 2 stops moving when it is in contact with the pressure regulating cabinet. It should also be added that the bottom of the mounting plate 4 and the mounting plate 7 are at the same horizontal position as the bottom of the pressure regulating cabinet body 1.

[0031] As shown in Figures 4 and 5, because the insulation rack 2 is U-shaped, it can insulate three sides of the pressure regulating cabinet. Then, the insulation board 3 is insulated against the other side (the cabinet door side) of the pressure regulating cabinet using the installation assembly. The installation assembly includes an installation block 12, an installation bracket 13, and bolts 14. The installation block 12 is fixedly installed on the side of the insulation rack 2, and a slot is provided on the side of the installation block 12. The installation bracket 13 is fixedly installed on the side of the insulation board 3, and the side of the installation bracket 13 is adapted to the slot. Bolt 14 is threaded onto the side of mounting bracket 13 and mounting block 12. Specifically, holding the insulation board 3, insert the side of mounting bracket 13 into the slot of mounting block 12. When the side of mounting bracket 13 is inserted into the slot of mounting block 12, the insulation board 3 adheres to the side of the pressure regulating cabinet body 1, thus providing insulation to one side of the cabinet door. The through groove of the insulation bracket 2 can pass through the handle of the cabinet door to avoid obstruction. Then, bolt 14 is threaded onto the side of mounting bracket 13 and mounting block 12 to fix them in place.

[0032] Working principle: When the high-protection gas metering and pressure regulating cabinet needs insulation, first turn the handle. The moving block 6, driven by the connecting block 10 and the connecting frame 11, moves the insulation frame 2 forward. On the other side, the sliding block 9 moves synchronously on the sliding rod 8 through the connection of the connecting block 10 and the connecting frame 11. The insulation frame 2 stops moving when it is in contact with the pressure regulating cabinet. Then, hold the insulation board 3 and insert the side of the mounting frame 13 into the slot of the mounting block 12 to insulate one side of the cabinet door. The through groove of the insulation frame 2 can pass through the handle of the cabinet door to avoid obstruction. Then, the bolt 14 is threaded onto the side of the mounting frame 13 and the mounting block 12 to fix it.

[0033] It should be added that insulation cotton is installed on the contact surfaces of insulation rack 2 and insulation board 3. When they are attached, the insulation cotton can be attached to the side wall of the pressure regulating cabinet. At this time, the insulation of the four side walls of the pressure regulating cabinet is completed. Since the pipes run through the top and bottom of the pressure regulating cabinet, there is no need to attach insulation cotton to the top and bottom of the pressure regulating cabinet. This facilitates subsequent maintenance and avoids pipe obstruction. When the weather warms up or the pressure regulating cabinet is turned on, bolt 14 can be unscrewed, insulation board 3 can be removed, and the handle can be turned to move insulation rack 2 away from the pressure regulating cabinet, so as to prevent the pressure regulating cabinet from having difficulty dissipating heat when the machine is turned on or when the temperature rises.

[0034] It should also be added that when insulation is not required, the screw 5 can be covered with a cover to prevent dust from contaminating it, and the staff will lubricate the screw 5 in a timely manner.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
