Description

Technical Field

[0001] This utility model relates to the field of flame arrester technology, and in particular to a flame arrester and pipeline equipment. Background Technology

[0002] In industries such as petrochemicals, chemicals, and gas, media are often transported through pipelines. Various flammable and explosive gases, liquid-gas mixtures, and particulate matter flow through these pipelines. Since these media are typically flammable and explosive, the risk of fire is significantly increased. Therefore, fire-prevention facilities such as flame arresters need to be installed in pipelines to prevent fires. The principle of a flame arrester is to pass the flame through the tiny channels of the flame-arresting element and cool it within those channels. When the flame is divided and reduced to a certain extent, the heat removed through the channels is sufficient to lower the temperature below the ignition point of the combustible material, extinguishing the flame. Existing flame arresters generally use a circular, integrated flame-arresting core with a small cross-sectional area, and the core is integrally installed inside the valve body.

[0003] However, the shortcomings of the existing technology are that maintenance is inconvenient. When it is necessary to clean the flame arrestor core, the flame arrestor needs to be removed from the system pipeline one by one and disassembled for cleaning and maintenance. The existing disassembly and installation process is cumbersome, time-consuming and labor-intensive, and inconvenient to operate, resulting in low work efficiency during maintenance. In addition, due to frequent disassembly and assembly, improper installation may lead to seal failure, causing media leakage and other safety accidents, posing safety hazards. Utility Model Content

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0033] Reference Figures 1 to 7 As shown, a flame arrester of this utility model includes a valve body unit, which includes a body 1, an explosion-proof cover 2, and a locking assembly. The body 1 has a receiving cavity with an opening at one end. One end of the explosion-proof cover 2 is hinged to the body 1, and the other end of the explosion-proof cover 2 is closably connected to the opening through the locking assembly, thereby enabling the receiving cavity to be closed or opened.

[0034] The flame arrester also includes a flame arresting core unit, which includes a flame arresting core 3 and a mounting assembly 4. The flame arresting core 3 and the mounting assembly 4 are housed in the receiving cavity. The flame arresting core 3 is detachably disposed in the receiving cavity, and the flame arresting core 3 can be fixed in the receiving cavity by the mounting assembly 4. By adjusting the mounting assembly 4, the flame arresting core 3 can be clamped or released.

[0035] Therefore, it can be understood that the flame arrester protected by this utility model is provided with a valve body unit and a flame arresting core unit. The valve body unit includes a body and an explosion-proof cover plate. The body has a receiving cavity with an opening at one end. The explosion-proof cover plate is movably disposed at the opening to close or open the receiving cavity. The flame arresting core unit includes a flame arresting core and an installation assembly. The flame arresting core and the installation assembly are housed in the receiving cavity. The flame arresting core is detachably disposed in the receiving cavity. At the same time, the flame arresting core can also be fixed in the receiving cavity by the installation assembly. With this configuration, by adjusting the installation assembly, the flame arresting core can be clamped or released, thereby facilitating the removal of the flame arresting core from the receiving cavity for maintenance, cleaning, or replacement. This utility model can effectively improve the work efficiency of flame arrester disassembly and assembly, reduce the labor intensity during maintenance, improve the convenience and safety of maintenance, reduce the amount of on-site disassembly and assembly work, reduce safety hazards, and is conducive to safe production.

[0036] In a preferred embodiment, the mounting assembly 4 includes a pop-out assembly, which includes a frame 41, an abutment assembly, and a connecting plate 42. The frame 41 is disposed along the height of the accommodating cavity, and the frame 41 has a receiving space for accommodating the connecting plate 42, with the connecting plate 42 disposed within the receiving space.

[0037] The connecting plate 42 is elastically connected to the bottom of the accommodating cavity, and the connecting plate 42 is rotatably connected to the abutting component. When the connecting plate 42 moves along the height direction, it can drive the abutting component to rotate. With this configuration, when the explosion-proof cover 2 closes the accommodating cavity, the explosion-proof cover 2 presses down on the connecting plate 42, and the abutting component moves under the drive of the connecting plate 42 to abut against the flame arrestor core 3, so that the flame arrestor core 3 is fixed in the accommodating cavity.

[0038] Furthermore, the pop-out assembly also includes a base plate 43 and an elastic element 44. The base plate 43 is installed at the bottom of the frame 41. One end of the elastic element 44 is connected to the base plate 43, and the other end of the elastic element 44 is connected to the connecting plate 42 to provide elastic support for the connecting plate 42. It should be noted that when the elastic element 44 only bears the weight of the connecting plate 42 and is not compressed, the connecting plate 42 protrudes from the opening of the receiving cavity.

[0039] In a preferred embodiment, to ensure the stability of the elastic element 44, a limiting groove is provided on the base plate 43, and the elastic element 44 is disposed in the limiting groove. The elastic element 44 includes, but is not limited to, a spring.

[0040] In detail, the abutting assembly includes at least one abutting plate 45. The frame 41 is provided with a limiting hole 46 that matches the abutting plate 45 on the side near the flame arrestor core 3. The limiting hole 46 extends along the height direction. One end of the abutting plate 45 is hinged to the connecting plate 42 through a rotating shaft 47. The other end of the abutting plate 45 passes through the limiting hole 46 and the rotation stroke is limited by the limiting hole 46.

[0041] In this way, when the explosion-proof cover 2 is closed, the connecting plate 42 is pressed downward by the explosion-proof cover 2, thereby driving the abutment plate 45 to rotate and clamp the flame arrestor core 3; when the explosion-proof cover 2 is opened, the connecting plate 42 pops upward, at which time the abutment plate 45 releases the flame arrestor core, so that the flame arrestor core 3 can be removed from the accommodating cavity for cleaning, maintenance or replacement.

[0042] In order to improve the uniformity of the pressing force on the flame arrester core 3 and ensure that the flame arrester core 3 achieves a better flame arresting effect when the flame arrester is working, three abutment plates 45 are provided at intervals along the height direction, and correspondingly, three limiting holes 46 are provided along the height direction, with each abutment plate 45 matching one limiting hole 46.

[0043] Specifically, the locking assembly includes an adjustable latch 20 and a connecting seat 21 that cooperates with the adjustable latch 20. The adjustable latch 20 can be snapped onto the connecting seat 21. The adjustable latch 20 is disposed on the explosion-proof cover 2, and the connecting seat 20 is disposed on the body 1. One end of the explosion-proof cover 2 is hinged to the body 1, and the other end of the explosion-proof cover 2 is connected to the body 1 through the adjustable latch 20.

[0044] In a preferred embodiment, in order to balance the force and ensure the stability and consistency of the flame arrester structure, two sets of ejection components are provided. The two sets of ejection components are arranged opposite to each other at both ends of the receiving cavity, so that the two sets of ejection components can act on both ends of the flame arrester core 3 respectively.

[0045] Furthermore, combining Figure 11 As shown, the flame-arresting core 3 includes a support 30 and a flame-arresting core body 31. The flame-arresting core body 31 is disposed on the support 30, and the support 30 has a cross-shaped structure. Specifically, the flame-arresting core body 31 includes flame-arresting steel, which is corrugated.

[0046] In a preferred embodiment, the cross-sectional shape of the flame arrestor core 3 is set to rectangular, thereby increasing the contact area between the flame and the channel wall, improving the transmission efficiency, and accelerating the cooling of the flame. Example 2

[0047] Unlike Embodiment 1, the installation component 4 includes a limiting plate assembly, as shown in the reference. Figures 8 to 10 As shown, the limiting plate assembly includes at least one limiting plate 48, which is detachably installed in the accommodating cavity. Both ends of the limiting plate 48 are bent toward the same side to form a baffle. The limiting plate 48 has a "U-shaped" structure. The baffle can abut against the flame arrestor core 3 to limit the flame arrestor core 3.

[0048] Specifically, the limiting plate 48 is detachably mounted to the body 1 by fasteners, including but not limited to bolts. When it is necessary to remove the flame arrestor core 3, the fasteners are adjusted to loosen the limiting plate 48, so as to facilitate the removal of the flame arrestor core 3.

[0049] To improve the uniformity of force on the flame arrestor core 3, the limiting plate assembly includes two limiting plates 48 arranged opposite to each other.

[0050] In a preferred embodiment, one end of the explosion-proof cover 2 is hinged to the body 1 via a hinge shaft, allowing the explosion-proof cover 2 to rotate around the hinge shaft. The locking assembly includes a hinge bolt 10 and a wing nut 11. The hinge bolt 10 is rotatably mounted on the body 1, and the explosion-proof cover 2 has a U-shaped mounting hole that mates with it. Thus, when the hinge bolt 10 is engaged in the U-shaped mounting hole, the wing nut 11 can be tightened or loosened to quickly open and close the explosion-proof cover 2.

[0051] After a period of use, the flame arrestor core 3 will accumulate dirt and other impurities, affecting the flame arrestor's performance. In this case, the flame arrestor core 3 needs to be cleaned or replaced. First, loosen the wing nut 11 on the explosion-proof cover 2, then open the explosion-proof cover 2. Next, loosen the fasteners used to fix the limiting plate 48, remove the flame arrestor core 3, and clean or replace it directly. Example 3

[0052] This utility model also discloses a pipeline device, combined with Figures 1-11 As shown, the pipeline equipment includes a pipeline body 5 and a flame arrester as described in Embodiment 1 or Embodiment 2, wherein the flame arrester is installed on the pipeline body 5.
