Description

Technical Field

[0001] This utility model relates to the field of valve well technology, specifically to an assembled modular gas valve well structure. Background Technology

[0002] A valve well is a pit (or well) set up in underground pipelines (such as water, oil, and natural gas pipelines) to facilitate the opening and closing of parts of the pipeline network or for maintenance work. It resembles a small room, where valves and other equipment are installed. This facilitates regular inspection, cleaning, and unblocking of the pipeline, preventing blockages. Valves are essential equipment for the safe operation, maintenance, renovation, and development of gas transmission, distribution, and storage systems; the installation of valve wells is crucial for protecting underground valves.

[0003] A search revealed that patent document CN210636461U discloses a leak-proof gas valve well, including a well cover and a well body. An elastic device is fixedly connected to the upper end of one side of the well body. The elastic device includes a support rod and a fixing plate. The middle part of the fixing plate is fixedly connected to the support rod, and a movable plate is movably connected to the middle part of the support rod. A spring is sleeved on the surface of the support rod, and one end of the spring is fixedly connected to the fixing plate. Through the cooperative arrangement of the first rubber layer, the first sealing gasket, the second rubber layer, and the second sealing gasket, a better seal is achieved, preventing gas leakage from the gas valve well and avoiding the hazards caused by gas leakage. The hollow groove and support column reduce the weight of the well cover, facilitating transportation. The cooperative arrangement of the support rod, spring, sleeve, fixing plate, and movable plate allows the well cover to automatically spring up, facilitating opening and regular inspection.

[0004] However, the fixed structure of this valve well cannot be adapted to gas pipeline installations of different depths, resulting in low applicability and failing to meet people's usage needs. Therefore, a modular gas valve well structure is proposed to solve the problems mentioned above. Utility Model Content

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.

[0021] Please see Figures 1 to 8 This embodiment of a modular gas valve well structure includes a base frame 1. Two pipe perforations 11 are provided on the side walls of the base frame 1, symmetrically distributed on both sides of the base frame 1. Depending on the gas pipeline installation layout, in other embodiments, the two pipe perforations 11 can also be asymmetrically arranged on both sides of the base frame 1 to facilitate the connection of the gas pipeline into the base frame 1 for valve installation. Simultaneously, a reinforcing seat 12 is provided at the bottom of the base frame 1. The reinforcing seat 12 increases the bottom contact area of ​​the base frame 1, improving the bottom structural strength of the base frame 1 and contributing to the structural strength of the well body.

[0022] A combination frame 2 is provided on the upper side of the bottom frame 1. The number of combination frames 2 can be set to one or more according to the installation depth of the gas pipeline, so as to facilitate the assembly of different heights and improve applicability.

[0023] A top frame 3 is provided on the upper side of the combination frame 2. A protruding plate 33 is provided on the top of the top frame 3. The protruding plate 33 can increase the contact area between the top frame 3 and the ground, which helps to improve the structural strength of the well body. A cover plate 31 is hinged to the upper side of the top frame 3. A bracket 32 ​​is provided on the inner side of the top frame 3, which is opposite to the position of the cover plate 31. The bracket 32 ​​is fixedly welded to the inner side of the top frame 3. When the cover plate 31 is placed on the top of the top frame 3, the bracket 32 ​​contacts the bottom of the cover plate 31 to support the cover plate 31.

[0024] It should be noted that the inner walls of the bottom frame 1, the combination frame 2, and the top frame 3 are all fixedly installed with steel bars 8. The steel bars 8 can be used as ladders to assist workers in climbing inside the well, making it convenient to install and maintain the valves inside the well.

[0025] The upper ends of the bottom frame 1 and the combined frame 2 are provided with mounting grooves 4. The lower ends of the combined frame 2 and the top frame 3 are provided with assemblies 5 that are compatible with the mounting grooves 4. The upper side walls of the bottom frame 1 and the combined frame 2 are provided with first fixing plates 6. The first fixing plates 6 are fixedly welded to the side walls of the bottom frame 1 or the combined frame 2. A connecting block 62 is slidably installed on the outer wall of the first fixing plate 6. A slot 63 is opened on the inner side of the connecting block 62. A threaded hole 64 is provided on the connecting block 62 that passes through both sides of the slot 63.

[0026] It should be noted that there are two first fixing plates 6 on the upper sidewalls of both the bottom frame 1 and the combined frame 2, and they are symmetrically arranged on both sides. In order to ensure the stability of the assembly, in other embodiments, there may also be four first fixing plates 6 on the upper sidewalls of both the bottom frame 1 and the combined frame 2, and they may be arranged on the four sides.

[0027] The lower sidewalls of both the combination frame 2 and the top frame 3 are provided with a second fixing plate 7. The second fixing plate 7 is fixedly welded to the sidewall of the combination frame 2 or the top frame 3. The bottom of the second fixing plate 7 is provided with a mounting piece 71 that is compatible with the slot 63. The mounting piece 71 is fixedly welded to the bottom of the second fixing plate 7. The mounting piece 71 is provided with a through hole 72. When the mounting piece 71 is engaged with the slot 63, the through hole 72 on the mounting piece 71 is aligned with the threaded hole 64 on the connecting block 62. The mounting piece 71 and the connecting block 62 can be fixed by bolts. When the mounting piece 71 and the connecting block 62 are fixed, the first fixing plate 6 and the second fixing plate 7 are held together, thereby realizing the combination and fixation of the bottom frame 1 and the combination frame 2 (or the combination frame 2 and the top frame 3), and thus realizing the assembly and combination of the valve well structure.

[0028] It should be noted that there are two second fixing plates 7 on the lower side walls of both the composite frame 2 and the top frame 3, and they are symmetrically arranged on both sides. In order to ensure the stability of the assembly, in other embodiments, there may also be four second fixing plates 7 on the lower side walls of both the composite frame 2 and the top frame 3, and they may be arranged on the four sides.

[0029] It should be noted that the first fixed plate 6 is provided with a movable hole 61, and a movable rod 65 is fixedly connected to the bottom of the connecting block 62. The movable rod 65 slides in cooperation with the inner side of the movable hole 61. When the connecting block 62 moves, it can drive the movable rod 65 to slide along the inner side of the movable hole 61, thereby realizing the stable adjustment of the position of the connecting block 62. Through the position adjustability of the connecting block 62, the problem of the mounting piece 71 not corresponding with the slot 63 in the connecting block 62 is avoided as much as possible.

[0030] The working principle of the above embodiments is as follows: In use, the bottom frame 1, the combination frame 2, and the top frame 3 are assembled together with the cooperation of the mounting groove 4 and the assembly 5, and set in the foundation pit for installing the gas pipeline. The number of combination frames 2 between the bottom frame 1 and the top frame 3 can be configured to be one or more according to the current installation depth of the gas pipeline. When the assembly 5 is in cooperation with the mounting groove 4, the first fixing plate 6 and the second fixing plate 7 on the bottom frame 1, the combination frame 2, and the top frame 3 correspond to each other. Through the setting of the movable rod 65 and the movable hole 61, the position of the connecting block 62 is adjustable, so that the connecting block 62 and the mounting piece 71 are stably connected. When the mounting piece 71 is in cooperation with the slot 63 on the connecting block 62, the through hole 72 on the mounting piece 71 and the threaded hole 64 on the connecting block 62 are opposite to each other. The mounting piece 71 and the connecting block 62 can be installed and fixed by bolts. When the mounting piece 71 and the connecting block 62 are fixed, the first fixing plate 6 and the second fixing plate 7 are held together, thereby realizing the combination and fixation between the bottom frame 1 and the combination frame 2, and between the combination frame 2 and the top frame 3, and thus realizing the assembly and combination of the valve well structure.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0032] The above description is a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this application, should be covered within the protection scope of the claims of this utility model.
