Description

Technical Field

[0001] This utility model relates to the field of gas pipeline construction equipment, and in particular to a gas pipeline purging port reinforcement and protection cover. Background Technology

[0002] Gas pipelines, as specialized facilities for transporting gas, occupy a crucial position in the modern energy supply system. Currently, metal gas hoses are gradually replacing traditional snap-fit ​​rubber hoses, effectively overcoming many drawbacks of rubber hoses such as easy detachment, easy aging, susceptibility to insect bites, and short service life, greatly improving the safety and stability of gas transmission.

[0003] Purging is an essential and indispensable step in the installation of gas pipelines. During manufacturing, transportation, and storage, various impurities, such as metal shavings, dust, and welding slag, inevitably get inside the pipelines. If these impurities remain inside the pipeline, they will not only accelerate wear on the inner wall of the pipeline and shorten its service life, but in severe cases, they may also cause blockages, affecting the normal delivery of gas and even leading to safety accidents.

[0004] However, existing gas pipeline purging operations have significant problems. During the purging process, a large amount of debris and impurities are ejected at high speed from the purging port. On the one hand, these ejected contaminants have a certain kinetic energy and are very likely to cause accidental injuries to people in the surrounding area, such as eye injuries or skin injuries, posing a significant safety hazard. On the other hand, the impurities sprayed everywhere are scattered over a wide area, increasing the difficulty of cleaning. This not only consumes a lot of time and energy of the staff, but may also pollute the working environment and affect the cleanliness and hygiene of the workplace.

[0005] Therefore, it is necessary to provide a reinforced protective cover for the gas pipeline purging port to solve the above-mentioned technical problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] First Embodiment

[0030] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a gas pipeline purge port reinforcement and protection cover provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the protective and buffer components. Figure 3 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2The enlarged schematic diagram of section B is shown. A reinforced protective cover for a gas pipeline purge port includes: a mounting plate 1;

[0031] Connection component 2, which is disposed on one side of the mounting plate 1;

[0032] A buffer assembly 3 is disposed on the other side of the mounting plate 1. The buffer assembly 3 includes a connecting pipe 31, a moving pipe 32, a sliding groove 33, a limiting plate 34, and a buffer spring 35. The connecting pipe 31 is fixedly installed on the other side of the mounting plate 1. The moving pipe 32 is sleeved on the outer side of the connecting pipe 31. The sliding groove 33 is opened on the inner side of the moving pipe 32. The limiting plate 34 is fixedly installed on the outer side of the connecting pipe 31. The buffer spring 35 is disposed on the outer side of the connecting pipe 31.

[0033] Protective component 4, the protective component 4 being disposed on the outer surface of the buffer component 3, the protective component 4 It includes a threaded ring 41 and a cover 42. The threaded ring 41 is threadedly connected to the outer side of the moving tube 32, and the cover 42 is fixedly installed on one end of the threaded ring 41.

[0034] A collection component 5 is disposed on the inner side of the cover 42. The collection component 5 includes a filter bag 51 and a threaded sleeve 52. The threaded sleeve 52 is threadedly connected to the inner side of the cover 42, and the filter bag 51 is fixedly installed on one end of the threaded sleeve 52.

[0035] The connection component 2 includes a multi-stage stepped interface 21 and multiple sealing gaskets 22. The multi-stage stepped interface 21 is fixedly installed on one side of the mounting plate 1, and the multiple sealing gaskets 22 are all disposed on the outer side of the multi-stage stepped interface 21.

[0036] The limiting plate 34 is also slidably connected to the inner side of the slide groove 33, and the buffer spring 35 is disposed on the inner side of the slide groove 33.

[0037] Multiple rotating plates 53 are fixedly installed on the inner side of the threaded sleeve 52.

[0038] When in use, the buffer spring 35 in the buffer assembly 3 plays a buffering role when the impact force of gas and impurities is large, reducing the damage of the impact force to the protective cover, extending the service life of the protective cover, and also reducing the potential impact on surrounding equipment and facilities.

[0039] The connecting component 2 is located on one side of the mounting plate 1 and consists of a multi-stage stepped interface 21 and multiple sealing gaskets 22. The multi-stage stepped interface 21 has a stepped structure with different diameters. This structure can be adapted to the purging ports of gas pipelines with different diameters. During actual installation, the operator can select the appropriate stepped part to insert according to the specific size of the purging port to ensure that the interface and the purging port fit tightly. Multiple sealing gaskets 22 are arranged around the outer side of the multi-stage stepped interface 21. The sealing gaskets are made of rubber, which has good elasticity and sealing performance. During the installation process, when the multi-stage stepped interface 21 is inserted into the purging port, the sealing gaskets will be squeezed to fill the gap between the interface and the purging port, effectively preventing gas and impurities from leaking during the purging process. This ensures that the purging operation is carried out in a relatively closed environment, protecting the safety of surrounding personnel and the cleanliness of the working environment.

[0040] The filter bag 51 is made of fine filter material, such as polyester fiber filter mesh. This filter mesh can effectively filter impurities in the gas, trapping metal shavings, dust, welding slag and other impurities inside the filter bag, allowing only the purified gas to be discharged.

[0041] With the rotating plate 53 in use, the user can easily rotate the threaded sleeve 52 by rotating the rotating plate 53, so that the threaded sleeve 52 is threadedly connected to the inner side of the cover 42, which makes it convenient for the user to disassemble and clean the threaded sleeve 52 and the filter bag 51.

[0042] The working principle of the gas pipeline purge port reinforcement and protective cover provided by this utility model is as follows:

[0043] When in use, the operator inserts the multi-step interface 21 into the inner side of the purge port, and then makes the multi-step interface 21 and the purge port threaded together to install the protective cover. During subsequent purging, the gas carries impurities through the buffer component 3 into the inner side of the cover 42. At this time, when the inner side of the cover 42 is installed, the filter bag 51 can filter the impurities in the gas, causing the impurities to accumulate on the inner side of the filter bag 51.

[0044] Furthermore, when the impact force is large, the moving tube 32 will slide on the outer side of the connecting tube 31, and the limiting plate 34 will slide on the inner side of the slide groove 33, thereby squeezing the buffer spring 35 and thus playing a buffering role.

[0045] Compared with related technologies, the gas pipeline purge port reinforcement and protection cover provided by this utility model has the following beneficial effects:

[0046] When in use, the cover of the protective component 4 can block impurities from splashing and avoid accidental injury to surrounding personnel; and the filter bag 51 of the collection component 5 can effectively collect impurities, prevent impurities from scattering everywhere, reduce cleaning difficulty, and keep the working environment clean.

[0047] Second Embodiment

[0048] Please refer to the following: Figure 5 Based on the first embodiment of this application which provides a reinforced protective cover for a gas pipeline purge port, the second embodiment of this application proposes another reinforced protective cover for a gas pipeline purge port. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0049] Specifically, the second embodiment of this application provides a gas pipeline purge port reinforcement and protection cover, which differs in that the gas pipeline purge port reinforcement and protection cover has side frames 6 fixedly installed on both sides of the mounting plate 1, and an extension frame 61 is slidably connected inside the side frame 6, and the extension frame 61 is internally threadedly connected to a threaded rod 62.

[0050] A handle 64 is fixedly installed at one end of the threaded rod 62.

[0051] A baffle 63 is fixedly installed at the other end of the outer side of the threaded rod 62.

[0052] The working principle of the gas pipeline purge port reinforcement and protective cover provided by this utility model is as follows:

[0053] When using the protective cover, if it is necessary to connect it to the purge port with the flange, the operator first inserts the multi-step interface 21 into the inside of the flange, then inserts one end of the threaded rod 62 into the threaded hole of the flange, and makes the baffle 63 abut against one side of the flange. Then the user rotates the handle 64, which drives the threaded rod 62 to make a threaded connection inside the extension frame 61, thereby making the multi-step interface 21 abut against the flange interface, thus achieving the function of installing the protective cover.

[0054] Compared with related technologies, the gas pipeline purge port reinforcement and protection cover provided by this utility model has the following beneficial effects:

[0055] The protective cover is made more adaptable by using a combination of structures such as side frame 6, extension frame 61, threaded rod 62, baffle 63 and rotating handle 64 to connect the protective cover to the purge port with flange interface during use.
