Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas distribution equipment technology, and in particular to a dual-redundant gas pressure regulating box. Background Technology
[0002] Gas pressure regulating boxes are an important component of gas transmission and distribution systems. Their main function is to regulate and stabilize gas system pressure and control gas flow to ensure system safety. Currently, the pressure regulating components inside gas pressure regulating boxes are single-unit units. When these components malfunction or require routine maintenance, gas supply to users is interrupted, causing significant inconvenience. Furthermore, the lack of redundancy in case of sealing leaks in the pressure regulating components can lead to complete gas supply disruption. Therefore, improvements are needed. Utility Model Content
[0003] Therefore, it is necessary to provide a dual-redundant gas pressure regulating box to address the above problems.
[0004] A dual-redundant gas pressure regulating box includes a box body, a first pressure regulating component, a second pressure regulating component, and a base. The first and second pressure regulating components are arranged side by side inside the box body. The base is installed at the bottom of the box body for connection with a gas pipeline.

[0005] Preferably, both the first and second pressure regulating components include an inlet connector, an inlet throttle valve, a delivery pipeline, a pressure regulator, a pressure gauge, an outlet connector, and an outlet throttle valve. The pressure regulator and pressure gauge are both installed on the delivery pipeline.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0014] like Figures 1-2As shown, a dual-redundant gas pressure regulating box includes a box body 1, a first pressure regulating component 2, a second pressure regulating component 3, and a base 4. The first pressure regulating component 2 and the second pressure regulating component 3 are arranged side by side inside the box body 1. The base 4 is installed at the bottom of the box body 1 for connection to a gas pipeline. The base 4 includes an outer frame 41, clamps 42, and a sliding groove 43. The outer frame 41 is arranged around the periphery of the box body 1, the sliding groove 43 is installed at the bottom of the box body, and several clamps 42 are movably installed in the sliding groove 43 for detachable connection to the gas pipeline. Specifically, in this embodiment, the box body 1 is made of metal, with high structural strength and strong protective capability. The outer surface of the box body 1 is treated with anti-corrosion to improve the service life of the box body 1 outdoors. The housing 1 integrates a first pressure regulating component 2 and a second pressure regulating component 3 connected in parallel. Both ends of the first pressure regulating component 2 and the second pressure regulating component 3 are connected to the gas pipeline. Under normal conditions, the first pressure regulating component 2 or the second pressure regulating component 3 serves as the main pressure regulator, while the other set serves as a backup. When the first pressure regulating component 2 or the second pressure regulating component 3 is damaged or requires normal maintenance, the backup set is activated to prevent gas outages for downstream users and improve the user experience. Simultaneously, the housing 1 contains two sets of pressure regulating components. We designed a base 4, which, in conjunction with the first pressure regulating component 2 and the second pressure regulating component 3, allows the housing 1 to be connected to the gas pipeline. Specifically, mutually perpendicular sliding grooves 43 are integrated at the bottom of the housing 1. Two of the sliding grooves 43 correspond to the first pressure regulating component 2 and the second pressure regulating component 3, while one sliding groove 43 is perpendicular to the two above, used for alignment with the main gas pipeline. Several clamps 42 are movably installed within the slide grooves 43. During installation, maintenance personnel can adjust the position of the clamps 42 along the slide grooves 43 as needed. The base 4 also includes an outer frame 41, which surrounds the housing 1, protecting the internal clamps 42 and slide grooves 43. Simultaneously, the outer frame 41 provides support, holding the housing 1 in place. When the first pressure regulating component 2 and the second pressure regulating component 3 are connected to the gas pipeline, the clamps 42 tighten the gas passage, improving the structural strength and stability of the connection between the housing 1 and the gas passage, avoiding reliance solely on the connection strength between the first pressure regulating component 2, the second pressure regulating component 3, and the gas pipeline. Because the slide grooves 43 are mutually perpendicular, once the clamps 42 located in the two mutually perpendicular slide grooves 43 tighten the gas pipeline, the housing 1 is fixed, preventing displacement on the horizontal plane. This eliminates the need for screws or other connectors to fix the housing 1 to the ground, facilitating subsequent disassembly and maintenance.
[0015] like Figure 1As shown, both the first pressure regulating component 2 and the second pressure regulating component 3 include an inlet connector 21, an inlet throttle valve 22, a delivery pipeline 23, a pressure regulator 24, a pressure gauge 25, an outlet connector 26, and an outlet throttle valve 27. The pressure regulator 24 and the pressure gauge 25 are both installed on the delivery pipeline 23. The pressure regulator 24 is used to regulate the gas flow rate through the delivery pipeline 23, and the pressure gauge 25 is used to detect the gas pressure through the delivery pipeline 23. The inlet throttle valve 22 and the outlet throttle valve 27 are respectively installed at both ends of the delivery pipeline 23. The inlet throttle valve 22 and the outlet throttle valve 27 are respectively connected to the gas pipeline through the inlet connector 21 and the outlet connector 26. Specifically, in this embodiment, the inlet throttle valve 22 and the outlet throttle valve 27 are connected to the gas pipeline through the inlet connector 21 and the outlet connector 22, respectively. The inlet connector 21 and the outlet connector 22 can adopt a corrugated connection structure, which is highly adaptable and suitable for some misaligned installation areas, reducing the risk of leakage. The inlet throttle valve 22 and the outlet throttle valve 27 are used to control the gas flow rate into and out of the delivery pipeline 23. The pressure regulator 24 integrated on the delivery pipeline 23 is responsible for dynamically adjusting the gas pressure and maintaining a stable gas output in the downstream gas pipeline. The pressure regulator 24 has a built-in overpressure shut-off valve for automatically cutting off the gas source when the pressure rises abnormally, and a safety relief valve for releasing gas to reduce the system pressure when overpressure occurs. The pressure gauge 25 is used to detect and display the gas pressure values into and out of the delivery pipeline 23, providing a more intuitive reading.
[0016] like Figure 1 As shown, the enclosure 1 also integrates a gas leak alarm light 5. Specifically, a gas leak detection sensor is installed inside the enclosure 1. When a gas leak is detected inside the enclosure 1, the detection sensor sends the detection information to the controller, which then controls the gas leak alarm light 5 to issue a warning to people in the surrounding area, prompting them to stay away and avoid safety accidents.
[0017] like Figure 1 As shown, the conveying pipeline 23 is also integrated with a filter 231. Specifically, the filter 231 is a stainless steel filter. The filter 231 is used to intercept dust and other particulate matter carried in the natural gas passing through the conveying pipeline 23, thereby improving the gas quality for downstream users and reducing the probability of carbon deposits in the gas stove after natural gas sintering.
[0018] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
