Description
Technical Field
[0001] The utility model relates to the technical field of pipeline flame arresters, in particular to a pipeline flame arrester. Background Art
[0002] Flame arresters are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. They are generally installed in pipelines that transport flammable gases or on ventilated tanks to prevent the spread of flames (deflagration or detonation). They are composed of a flame arrester core, a flame arrester shell, and accessories. The flame arrester core generally uses a flame arrester disc. The national standards for flame arrester discs cover classification, performance, test methods, use restrictions, and other aspects, aiming to ensure the safety and reliability of flame arresters to protect people's lives and property. With the advancement of technology and international needs, these standards are constantly being updated and improved. However, in order to ensure the flowability of the transported objects, the flame arrester disc can still ensure the flow of the transported objects while blocking the fire. Therefore, its fire blocking performance is limited. In order to avoid the fire blocking limit of the fire arrester disc being broken, a pipeline flame arrester is designed to facilitate interception when the flame is large and the flame arrester disc is about to break the fire blocking limit, so as to avoid the situation where the flame is large and the fire blocking limit of the flame arrester disc is broken, and to ensure the fire blocking performance of the pipeline flame arrester.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example:
[0022] See also Figure 1-4 A pipeline flame arrester comprises a fire-blocking pipeline 1, a blocking box 2 is fixedly connected in the middle of the fire-blocking pipeline 1, a fire-blocking disk 3 is fixedly installed on one side of the fire-blocking pipeline 1 located at the blocking box 2, a sealing plate 4 is sealingly and slidably matched with at least one side of the blocking box 2 that is connected to the fire-blocking pipeline 1, a temperature sensor 11 fixedly installed on the fire-blocking pipeline 1 is arranged on the side of the fire-blocking disk 3 away from the sealing plate 4, a driving mechanism for driving the sealing plate 4 to seal the connection between the fire-blocking pipeline 1 and the blocking box 2 is installed on the blocking box 2, and the temperature sensor 11 is electrically connected to the driving mechanism.
[0023] Specifically, the driving mechanism includes a gear 6 rotatably connected to the blocking box 2, a rack 7 meshing with the gear 6 is fixedly mounted on the sealing plate 4, and a driving member for driving the gear 6 to rotate is provided on the blocking box 2. When the driving member is started, the output shaft of the driving member rotates clockwise or counterclockwise, thereby driving the gear 6 to rotate clockwise or counterclockwise. Through the meshing of the gear 6 and the rack 7, the sealing plate 4 is driven to move left and right, thereby enabling the readable fire-blocking pipe 1 and the blocking box 2 to be sealed or contact-sealed. Furthermore, the driving member includes a blocking motor 9 fixedly mounted on the blocking box 2, and the output shaft seal of the blocking motor 9 passes through the blocking box 2 and is fixedly connected to the gear 6. When the blocking motor 9 is started, the output shaft of the blocking motor 9 rotates clockwise or counterclockwise, thereby driving the gear 6 to rotate clockwise or counterclockwise.
[0024] Specifically, the sealing plates 4 are arranged in two groups and are arranged on both sides of the blocking box 2, and the racks 7 on the two sealing plates 4 are meshed with the gear 6, and the fire-blocking disks 3 and the temperature sensors 11 are arranged in two groups and are arranged on both sides of the blocking box 2. The fire-blocking disks 3 are arranged in two groups, and the temperature sensors 11 on both sides are used to detect the temperature of the two fire-blocking disks 3 respectively, so as to facilitate timely sealing and blocking when there is a flame on either side, avoid the flame from spreading into the blocking box 2, and ensure the cleanliness and flamelessness of the inside of the blocking box 2. Furthermore, the sealing plate 4 is provided with a through arc 10 adapted to the connection between the fire-blocking pipe 1 and the blocking box 2.
[0025] Specifically, the gear 6 is arranged into two groups, and two groups of upper and lower racks 7 are fixedly mounted on the sealing plate 4. The upper and lower groups of gears 6 are fixedly connected by a rotating shaft 8. The two sealing plates 4 are adjusted by the two groups of gears 6 and the two racks 7 on the upper and lower sides of the sealing plate 4 to improve the stability of driving the sealing plate 4 to slide.
[0026] Specifically, the temperature sensor 11 is arranged at the top of the fire-blocking pipe 1. When the flame comes over, the temperature on the upper side of the fire-blocking pipe 1 is higher. The temperature sensor 11 arranged at the top can detect the position with the highest temperature.
[0027] Specifically, guide grooves are respectively provided on the top and bottom of the sealing plate 4, and the top and bottom of the blocking box 2 are fixedly connected with guide rails 5 that slide with the guide grooves. Through the cooperation between the guide rails 5 and the sealing plate 4, the stability of the guiding sliding of the sealing plate 4 is conveniently improved. Furthermore, flanges 12 are fixedly installed on both sides of the fire-blocking pipe 1, and the flanges 12 are used to conveniently connect the fire-blocking pipe 1 with the conveying pipe.
[0028] When in use, the pipeline flame arrester is installed in the pipeline of the circulating object. When a fire occurs, the flame passes through the fire-blocking pipeline 1 along the flow direction of the circulating object, and is blocked by the fire-blocking disk 3. At the same time, the circulation of the circulating object is guaranteed. When the flame is so large that the fire-blocking disk 3 is about to break through the fire-blocking limit, the temperature sensor 11 detects that the temperature is high and transmits a signal to the driving mechanism, which starts the driving mechanism and drives the sealing plate 4 to intercept the connection between the fire-blocking pipeline 1 and the blocking box 2, so as to prevent the flame from spreading by blocking the circulation.
