Description

Technical Field

[0001] This utility model relates to the field of chemical fire prevention technology, specifically to a fire-safe pipeline. Background Technology

[0002] Chemical enterprises, due to the presence of many flammable and explosive substances in their production processes, are prone to fires. Therefore, fire protection is a key area that these enterprises need to focus on. Most fire protection systems in chemical enterprises are designed to effectively extinguish fires and prevent their spread, thereby avoiding the escalation of fire accidents. For example, Chinese Patent 201620680845.4 discloses a chemical fire control system, including a fire controller connected to a dual-power supply module, a pipeline water supply pressure stabilization module, a fire monitoring module, and an alarm display module.

[0003] Currently, in the event of a fire in a chemical plant, the fire may spread along pipes made of plastic materials. To prevent the fire from spreading, metal barrier sections are commonly installed. However, for pipes carrying flammable liquids, the metal barrier sections are completely ineffective. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a fire-safe pipeline to solve the technical problem that the metal barrier section of the pipeline containing flammable liquids completely fails in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a fire-safe conduit, comprising:

[0007] The safety conduit has a first docking plate at both ends;

[0008] The connecting pipe has a connecting flange at one end for connecting to the working pipe, and a second mating plate at the other end;

[0009] The clamping mechanism has a movable clamping end, and has a first position state in which it clamps the first and second mating discs on both sides to form communication between the two ends of the safety conduit and the connecting pipe, and a second position state in which it releases the clamping and separates the two ends of the safety conduit from the connecting pipe; and

[0010] A sealing ring is sandwiched between the corresponding first mating plate and the second mating plate.

[0011] In some embodiments, the clamping mechanism includes a first clamping component and a second clamping component. The first clamping component is used to press a first mating plate on one side against a second mating plate, and the second clamping component is used to press a second mating plate on the other side against a first mating plate. The first clamping component is also used to push the safety conduit downward when the clamping is released.

[0012] In some embodiments, the safety conduit is in the shape of a square tube.

[0013] In some embodiments, both the first docking plate and the second docking plate are square in shape.

[0014] In some embodiments, the first clamping assembly includes a first frame, a first hydraulic push rod, a first connecting rod, a first pressure head, a second hydraulic push rod, and a push plate. The first hydraulic push rod is mounted on the first frame, the first connecting rod is connected to the telescopic end of the first hydraulic push rod for axial extension and retraction along the safety conduit, and the push plate is connected to the telescopic end of the second hydraulic push rod for radial extension and retraction along the safety conduit.

[0015] In some embodiments, the second clamping assembly includes a second frame, a third hydraulic push rod, a second connecting rod, and a second pressure head. The third hydraulic push rod is mounted on the second frame, and the second connecting rod is connected to the telescopic end of the second hydraulic push rod for axial extension and retraction along the safety conduit.

[0016] In some embodiments, there are two of each of the first hydraulic push rod, the third hydraulic push rod, the first connecting rod, and the second connecting rod.

[0018] In some embodiments, both the second mating plate and the first mating plate are provided with annular grooves, and both sides of the sealing ring have annular protrusions that are embedded in the annular grooves.

[0019] In some embodiments, the connecting pipe is a metal pipe.

[0020] Compared with the prior art, the fire safety conduit provided by this utility model, through the safety conduit, connecting conduit, clamping mechanism and sealing ring, can be inserted into the normal working conduit in a clamping connection manner.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] To address the technical problem of complete failure of metal barrier sections in pipelines carrying flammable liquids, this invention provides a fire-safe pipeline that can effectively prevent the spread of combustion along the pipeline even when the medium is a flammable liquid.

[0034] It should be noted that the fire-safe pipeline described in this utility model is used in, but not limited to, chemical enterprises. For ease of explanation, this utility model only uses the application of the fire-safe pipeline in a chemical enterprise with a flammable liquid as an example. The principle of the fire-safe pipeline in other enterprises to prevent the spread of pipeline fires is essentially the same as that in the application of the fire-safe pipeline in a chemical enterprise with a flammable liquid as a medium, and will not be elaborated here.

[0035] See also Figure 1 , Figure 1 This is a schematic diagram of the fire safety conduit in one embodiment of the present invention. The fire safety conduit includes a safety conduit 1, a connecting conduit 2, a clamping mechanism 3, and a sealing ring 4. Both ends of the safety conduit 1 are provided with first mating discs 101. One end of the connecting conduit 2 is provided with a connecting flange 201 for connecting to the working conduit 5, and the other end is provided with a second mating disc 202. Both the first mating discs 101 and the second mating discs 202 are non-perforated annular discs, which are pressed together to form a connection. The clamping mechanism 3 is provided with a movable clamping end, which presses the first mating discs 101 and the second mating discs 202 on both sides to allow the two ends of the safety conduit 1 to respectively connect with the connecting conduit 2. The system forms a first position state where the connection is established, and a second position state where the pressure is released, separating both ends of the safety conduit 1 from the connecting conduit 2. In the first position state, the first mating plate 101 and the second mating plate 202 are pressed together to form a connection. In the second position state, the first mating plate 101 and the second mating plate 202 are not subjected to external force, and the pressure fails, thus disconnecting the connection. Due to its own weight, the safety conduit 1 naturally falls downward, thereby preventing the spread of fire. The sealing ring 4 is sandwiched between the corresponding first mating plate 101 and the second mating plate 202. When the first mating plate 101 and the second mating plate 202 are pressed together, a seal is provided to prevent leakage of internal media.

[0036] In this embodiment, to insert the safety conduit 1 into the normal working conduit 5, the connecting flange 201 on the connecting conduit 2 is connected to the working conduit 5 with bolts and nuts. Then, the clamping mechanism 3 uses a clamping method to press and connect the working conduit 5 with the first mating plate 101 and the second mating plate 202 on the connecting conduit 2, thereby achieving the purpose of inserting the safety conduit 1. Under normal circumstances, the clamping mechanism 3 clamps to form an effective connection, and can be loosened when necessary without preventing the safety conduit from falling out. Please refer to [link to previous document]. Figure 3 In the event of a fire, the clamping mechanism 3 will automatically or manually release, and the safety pipe 1 will detach from the middle, thereby preventing the fire from spreading.

[0037] In one embodiment, please refer to Figure 1 and Figure 2 The clamping mechanism 3 includes a first clamping component 31 and a second clamping component 32. The pipes are installed sequentially from left to right. First, the connecting pipe 2 on the left is connected to the working pipe 5 on the left. Then, the first clamping component 31 pushes against the first mating plate 101 and the second mating plate 202 on one side to press them together, connecting the safety pipe 1 to them. Next, the second clamping component 32 pushes against the second mating plate 202 and the first mating plate 101 on the other side to press them together, connecting the connecting pipe 2 at the other end to the safety pipe 1. Finally, the working pipe 5 on the right is connected to the connecting pipe 2. Additionally, the first clamping component 31 is also used to push the safety pipe 1 downwards when the clamping is released, preventing the safety pipe 1 from failing to fall effectively after the pressure clamping is released.

[0038] Furthermore, to avoid interference with the descent of the safety conduit 1 due to compression, the safety conduit 1 is in the shape of a square tube, and both the first docking plate 101 and the second docking plate 202 are square in shape. The length and width of the docking plates are greater than the length and width of the safety conduit, so that the safety conduit 1 can be clamped at multiple points evenly distributed on both sides of the docking plates to form compression.

[0039] Furthermore, the first clamping assembly 31 includes a first frame 311, a first hydraulic push rod 312, a first connecting rod 313, a first pressure head 314, a second hydraulic push rod 315, and a push plate 316. The first hydraulic push rod 312 is mounted on the first frame 311, and the first frame 311 is fixed to the ceiling. The first connecting rod 313 is connected to the telescopic end of the first hydraulic push rod 312 and is used to extend and retract along the axial direction of the safety pipe 1, pushing against the first pressure head 314 to press the first mating plate 101 and the second mating plate 202 together. The push plate 316 is connected to the telescopic end of the second hydraulic push rod 315 and is used to extend and retract radially along the safety pipe 1. In the second position state, the push plate 316 is pushed down to push the safety pipe 1 downward.

[0040] Furthermore, the second clamping assembly 32 includes a second frame 321, a third hydraulic push rod 322, a second connecting rod 323, and a second pressure head 324. The second frame 321 is fixed to the ceiling. The third hydraulic push rod 322 is mounted on the second frame 321. The second connecting rod 323 is connected to the telescopic end of the second hydraulic push rod 315 and is used to extend and retract along the axial direction of the safety pipe 1, pushing against the second pressure head 324 to press the second mating plate 202 on the other side against the first mating plate 101.

[0041] Preferably, there are two of each of the first hydraulic push rod 312, the third hydraulic push rod 322, the first connecting rod 313, and the second connecting rod 323. One second connecting rod 323 is connected to two first pressure heads 314, and another second connecting rod 323 is connected to two second pressure heads 324. The four first pressure heads 314 are placed at the four corners of the first docking plate 101, and the four second pressure heads 324 are placed at the four corners of the second docking plate 202, forming a four-corner pressing to ensure that the pipe is pressed tightly. They are located on both sides of the safety pipe 1, so as to avoid interfering with the fall of the safety pipe 1 while effectively pressing it.

[0042] In one embodiment, please refer to Figure 4 To enhance overall safety, both the first connecting rod 313 and the second connecting rod 323 are equipped with anti-drop brackets 6 at their bottoms. In the first position, the anti-drop brackets 6 are suspended below the first docking plate 101. In the second position, they are moved away from the first docking plate 101 and the second docking plate 202. The anti-drop brackets 6 are located on both sides of the safety pipe 1. In the second position, they do not interfere with the falling of the safety pipe 1. In the first position, they prevent the safety pipe 1 from falling.

[0043] In one embodiment, please refer to Figure 2 In order to improve the sealing performance of the sealing ring 4 and prevent displacement, annular grooves 203 are provided on both the second mating plate 202 and the first mating plate 101. Annular protrusions 401 are extended on both sides of the sealing ring 4 and embedded in the annular grooves 203. The annular protrusions 401 and the sealing ring 4 are made of the same elastic material and are embedded in the annular grooves 203 to form an interlocking concave-convex structure, which improves the sealing performance and has a certain positioning function.

[0044] Understandably, the annular groove 203 may not be provided on the first mating plate 101 to avoid jamming during falling. Correspondingly, if the annular groove 203 is not provided on the first mating plate 101, then the annular protrusion 401 will not be provided on the side of the sealing ring 4.

[0045] In one embodiment, to prevent the safety conduit 1 from disconnecting in a normal fire, the connecting conduit 2 is a metal conduit, so that in a normal fire, the spread of the fire can be stopped directly by a metal partition.

[0046] To better understand this utility model, the following is combined with... Figures 1 to 4The technical solution of this utility model is described in detail as follows: In the first position state, the first hydraulic push rod 312 pushes the first pressure head 314 to press the first docking plate 101 on the left side with the second docking plate 202 on the left side, and the third hydraulic push rod 322 pushes the second pressure head 324 to press the second docking plate 202 on the right side with the first docking plate 101 on the right side; In the second position state, the first hydraulic push rod 312 retracts, disengaging the first pressure head 314 from the first docking plate 101 on the left side, the third hydraulic push rod 322 retracts, disengaging the second pressure head 324 from the second docking plate 202 on the right side, and the second hydraulic push rod 315 pushes the push plate 316 downwards, pushing the safety pipe 1 down until it falls; wherein, the first position state is a situation where no fire has occurred, and the second position state is a situation where a fire has occurred and it is necessary to disconnect to prevent the fire from spreading along the pipe.

[0047] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
