Description

Technical Field

[0001] The utility model relates to the technical field of fire pipelines, in particular to a fire pipeline convenient for installation. Background Technique

[0002] A fire pipeline refers to pipeline materials used for fire protection, connecting fire-fighting equipment and appliances, and transporting fire-fighting water, gas or other media. Due to special requirements, the thickness and material of the fire pipeline have special requirements, and it is painted with red paint to transport fire-fighting water.

[0003] Before using the fire pipeline, it is necessary to splice and install multiple fire pipelines together through the flange plates at both ends of the fire pipeline.

[0004] However, the lengths of existing fire pipelines are fixed. When installing the fire pipeline not far from the wall, if the pipeline is too long, the fire pipeline needs to be cut. When the fire pipeline is short, multiple short fire pipelines need to be connected. The existing fire pipeline cannot adjust its length as needed, which is time-consuming and laborious and reduces work efficiency.

[0005] Moreover, when installing the existing fire pipeline, it is necessary to align the flange plates on two different fire pipelines and then fix them through fasteners. During the process of aligning and splicing the fire pipelines, if the fire pipeline is accidentally hit, its position will shift and it needs to be realigned, which is troublesome and cumbersome. Content of the Utility Model

[0006] The purpose of the utility model is to provide a fire pipeline convenient for installation to solve the problems raised in the above background technique.

[0007] In order to solve the above technical problems, the utility model provides the following technical solution: A fire pipeline convenient for installation, comprising:

[0008] A first pipeline;

[0009] An extension pipe located inside the first pipeline, and the extension pipe is used to increase and shorten the length of the pipeline;

[0010] One end of the first pipeline is provided with a connection block, one side of the connection block is connected to the first pipeline by welding, a groove is opened at the end of the connection block far from the first pipeline, one end of the extension pipe is connected to the first pipeline by embedding at the end of the first pipeline far from the connection block, a flange plate is provided at the end of the extension pipe far from the first pipeline, one side of the flange plate is connected to the first pipeline by welding, a threaded column is provided outside the connection block, and one end of the threaded column is connected to a moving plate through a rotating shaft.

[0011] Preferably, a support block is provided on one side of the connection block. One side of the support block is connected to the outer wall of the connection block by welding, and a threaded column is connected to the inside of the support block by threading.

[0012] Preferably, a knob is provided at one end of the threaded column away from the moving plate. The knob is connected to the threaded column by a fastener, and the moving plates are symmetrically distributed on the connection block.

[0013] Preferably, a rubber ring is wrapped around the outer wall of one end of the first pipe away from the connection block. A jacket is provided on the outer wall of the rubber ring, and the jacket is connected to the rubber ring by clamping.

[0014] Preferably, a rubber pad is provided on the inner wall of the groove. The rubber pad is connected to the inner wall of the groove by adhesion, and the groove fits the flange.

[0015] Preferably, a limiting rod is provided on one side of the moving plate. One end of the limiting rod is connected to the moving plate by welding, and the end of the limiting rod away from the moving plate is connected to the support block by passing through.

[0016] Preferably, a second pipe is provided at one end of the first pipe, and the extension pipe and the connection block are also provided on the second pipe.

[0017] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0018] First, by providing the extension pipe and the jacket, the present utility model can adjust the length of the fire pipeline as needed. When the length of the fire pipeline needs to be adjusted, turn the bolt on the jacket so that the jacket no longer clamps the rubber ring, and then pull the extension pipe to move by the flange until the extension pipe moves to an appropriate length. Then, seal and fix the connection between the extension pipe and the first pipe again through the jacket, and the adjustment of the length of the fire pipeline can be achieved without cutting and splicing short pipelines for the fire pipeline, saving time and effort and improving work efficiency.

[0019] Second, by providing the connection block and the moving plate, the present utility model can facilitate the splicing and installation of the fire pipeline. When the fire pipeline needs to be connected and installed, move the flange at one end of the second pipe into the groove of the connection block of the first pipe, and then rotate the threaded column by the knob. The threaded column moves on the support plate through the thread, and the movement of the threaded column drives the moving plate to move. The moving plate drives the limiting rod to slide on the support plate until the moving plate moves to the flange to squeeze and limit the flange, preventing the situation of easy deviation during the splicing and installation of the fire pipeline, and reflecting the practicability of this device.

[0027] Please refer to Figures 1-5 , a fire-fighting pipeline convenient for installation, including:

[0028] First pipeline 1;

[0029] An extension pipe 7 located inside the first pipeline 1, and the extension pipe 7 is used to increase and shorten the length of the pipeline;

[0030] One end of the first pipe 1 is provided with a connecting block 5. One side of the connecting block 5 is connected to the first pipe 1 by welding. A groove 14 is formed at one end of the connecting block 5 away from the first pipe 1. One end of the extension pipe 7 is connected to the end of the first pipe 1 away from the connecting block 5 by embedding. A flange 4 is provided at the end of the extension pipe 7 away from the first pipe 1. One side of the flange 4 is connected to the first pipe 1 by welding. A threaded post 10 is provided on the outer side of the connecting block 5. One end of the threaded post 10 is connected to the moving plate 6 by a rotating shaft. When it is necessary to adjust the length of the fire pipeline, turn the bolt on the jacket 3 so that the jacket 3 no longer clamps the rubber ring 8. Then pull the extension pipe 7 to move through the flange 4. Until the extension pipe 7 moves to an appropriate length, then seal and fix the connection between the extension pipe 7 and the first pipe 1 through the jacket 3 again, and the adjustment of the length of the fire pipeline can be achieved. There is no need to cut and splice short pipelines for the fire pipeline, which saves time and effort and improves work efficiency.

[0031] Specifically, a support block 9 is provided on one side of the connecting block 5. One side of the support block 9 is connected to the outer wall of the connecting block 5 by welding. The threaded post 10 is connected to the inside of the support block 9 by threading.

[0032] Through the above technical solution, the rubber ring 8 is used to seal the connection between the extension pipe 7 and the second pipe 2, preventing the water inside the first pipe 1 from flowing out through the connection.

[0033] Specifically, a knob 13 is provided at the end of the threaded post 10 away from the moving plate 6. The knob 13 is connected to the threaded post 10 by a fastener. The moving plates 6 are symmetrically distributed on the connecting block 5.

[0034] Through the above technical solution, the knob 13 is used for the staff to rotate the threaded post 10. The threaded post 10 is used to drive the moving plate 6 to squeeze and limit the flange 4 entering the groove 14, preventing it from moving out randomly, which is convenient for the staff to perform subsequent operations on it.

[0035] Specifically, a rubber ring 8 is wrapped around the outer wall of the end of the first pipe 1 away from the connecting block 5. A jacket 3 is provided on the outer wall of the rubber ring 8. The jacket 3 is connected to the rubber ring 8 by clamping.

[0036] Through the above technical solution, the size of the groove 14 of the connecting block 5 fits the size of the flange 4, which is convenient for the flange 4 to enter the inside of the groove 14 to be connected to the connecting block 5. When the flange 4 enters the groove 14 of the connecting block 5, it plays a supporting role for it, so it can prevent the pipeline from tilting.

[0037] Specifically, a rubber pad 11 is provided on the inner wall of the groove 14. The rubber pad 11 is connected to the inner wall of the groove 14 by adhesion. The groove 14 fits the flange 4.

[0038] Through the above technical solution, the groove 14 can further seal the connection through the rubber pad 11, improving the sealing effect at the connection.

[0039] Specifically, a limiting rod 12 is provided on one side of the moving plate 6. One end of the limiting rod 12 is connected to the moving plate 6 by welding, and the end of the limiting rod 12 away from the moving plate 6 is connected to the support block 9 by passing through.

[0040] Through the above technical solution, since the threaded column 10 is connected to the moving plate 6 through a rotating shaft, the limiting rod 12 prevents the moving plate 6 from rotating on the threaded column 10.

[0041] Specifically, a second pipe 2 is provided at one end of the first pipe 1, and an extension pipe 7 and an adapter block 5 are also provided on the second pipe 2.

[0042] Through the above technical solution, an extension pipe 7 is also provided inside the second pipe 2. At the same time, one end of the second pipe 2 is connected to the adapter block 5 by welding. This device is suitable for when the fire pipeline is not far from the wall. The pipelines of this device can be connected without splicing and cutting the pipelines.

[0043] When in use, first, when the length of the fire pipeline needs to be adjusted, turn the bolt on the jacket 3 so that the jacket 3 no longer clamps the rubber ring 8. Then, pull the extension pipe 7 to move through the flange 4 until the extension pipe 7 moves to the appropriate length. Then, seal and fix the connection between the extension pipe 7 and the first pipe 1 through the jacket 3 again. When the fire pipeline needs to be connected and installed, move the flange 4 at one end of the second pipe 2 into the groove 14 of the adapter block 5 of the first pipe 1, and then rotate the threaded column 10 by turning the knob 13. The threaded column 10 moves on the support plate through the thread. The movement of the threaded column 10 drives the moving plate 6 to move. The moving plate 6 drives the limiting rod 12 to slide on the support plate until the moving plate 6 moves to the flange 4 and squeezes and limits the flange 4, then the work is completed.
