Description

Technical Field

[0001] This utility model relates to an explosion-proof pipe for water supply systems, belonging to the field of pipeline technology. Background Technology

[0002] Airport water supply pipes are primarily used to transport domestic water, industrial water, and fire-fighting water, ensuring a continuous and stable water supply.

[0003] The existing water supply pipes used in airports only serve the purpose of supplying water and do not have the function of preventing water supply pipes from bursting. When soil subsidence causes uneven stress on underground pipes, or when the huge difference in water volume between peak and off-peak water use in summer causes the pipe pressure to exceed the bearing capacity, water supply pipes may burst. Once a water supply pipe bursts, it will seriously affect the normal water supply. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an explosion-proof pipe for a water supply system, so as to solve the technical problems existing in the prior art.

[0005] The technical solution adopted by this utility model is as follows: an explosion-proof pipe for a water supply system, comprising an outer pipe, a buffer layer and an inner pipe, wherein the interior of the inner pipe is used for water conveyance, the buffer layer is sleeved on the outer periphery of the inner pipe, and the outer pipe is sleeved on the outer periphery of the buffer layer.

[0006] Preferably, the buffer layer is a rubber layer.

[0007] Preferably, the outer tube is a steel pipe.

[0008] Preferably, the inner tube is a PE tube.

[0009] Preferably, a pressure sensor is installed inside the inner pipe, and two adjacent water supply pipes are connected by a sleeve. The sleeve is connected to a drive mechanism, and the pressure sensor is electrically connected to the drive mechanism through a controller.

[0010] Preferably, the sleeve is threadedly connected to two adjacent water supply pipe sections.

[0011] Preferably, the driving mechanism includes a gear ring fixed to the outer periphery of the sleeve, the gear ring meshing with a gear, the gear being driven by a motor, a fixed beam fixed on the frame, and the motor being slidably connected to the fixed beam.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model can play the role of explosion-proof pipe and anti-squeezing by setting an inner pipe, a buffer layer and a sleeve; by setting a sleeve and a driving mechanism, when the water pressure inside the pipe exceeds the standard, the driving mechanism drives the sleeve to disengage from the water supply pipe and the water is automatically discharged. When the water pressure inside the pipe returns to normal, the driving mechanism drives the sleeve to re-engage with the water supply pipe and resume water supply, thus preventing the water supply pipe from bursting.

[0014] Figure 2 This is a schematic diagram of the connection structure between two adjacent water supply pipe sections. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] The reference numerals in the accompanying drawings include: outer tube 1, buffer layer 2, inner tube 3, pressure sensor 4, sleeve 5, gear ring 6, gear 7, motor 9, locking block 9, fixed beam 10, first push plate 11, first connecting rod 12, second push plate 13, and second connecting rod 14.

[0017] Example 1:

[0018] An explosion-proof pipe for water supply systems, such as Figures 1-2 As shown, it includes an outer pipe 1, a buffer layer 2, and an inner pipe 3. The inner pipe 3 is a PE pipe, and the inside of the inner pipe 3 is used for water transportation. The buffer layer 2 is a rubber layer, which is fitted around the outer periphery of the inner pipe 3. The outer pipe 1 is a steel pipe, which is fitted around the outer periphery of the buffer layer 2.

[0019] The outer tube 1 serves as an explosion-proof layer, while the buffer layer 2 serves to reduce vibration and prevent crushing.

[0020] like Figure 1 As shown, a pressure sensor 4 is installed inside the inner tube 3, such as... Figure 2 As shown, two adjacent water supply pipes are connected by a sleeve 5. The sleeve 5 is threaded to the two adjacent water supply pipes. A gear ring 6 is fixed to the outer circumference of the sleeve 5, and a gear 7 meshes with the gear ring 6. A fixed beam 10 is fixed on the frame. A sliding groove is opened at the lower end of the fixed beam 10. A locking block 9 is slidably connected inside the sliding groove. The locking block 9 can only slide along the sliding groove but cannot slide out of the sliding groove. A motor 9 is fixed to the lower end of the locking block 9. The output shaft of the motor 9 is arranged horizontally to the left. The gear 7 is fixed to the output shaft of the motor 9. The pressure sensor 4 is electrically connected to the motor 9 through a controller. Figure 2As shown, a first push plate 11 is fixed to the outer casing of motor 9 via a first connecting rod 12. The first push plate 11 is vertically located on the left side of gear ring 6. A second push plate 13 is fixed to the outer casing of motor 9 via a second connecting rod 14. The second push plate 13 is located on the right side of gear ring 6.

[0021] The controller sets the upper and lower limits of the water pressure inside the pipe. When the pressure sensor 4 detects that the pressure inside the pipe exceeds the set upper limit, the pressure sensor 4 controls the motor 9 to rotate forward through the controller. The forward rotation of the motor 9 drives the gear 7 and the gear ring 6 to rotate forward. The forward rotation of the gear ring 6 drives the sleeve 5 to rotate forward. The sleeve 5 moves to the left and separates from the water supply pipe on the right side, and the water inside the water supply pipe flows out automatically, preventing the pipe from bursting. When the water pressure inside the pipe drops below the set lower limit, the pressure sensor 4 controls the motor 9 to rotate in reverse through the controller. The reverse rotation of the motor 9 drives the gear 7 and the gear ring 6 to rotate in reverse. The reverse rotation of the gear ring 6 drives the sleeve 5 to rotate in reverse. The sleeve 5 moves to the right and re-engages with the water supply pipe on the right side, and the water supply pipe can supply water again.

[0022] The function of the first push plate 11 and the second push plate 13 is to drive the gear ring 6 and the motor 9 to move synchronously left and right when the sleeve 5 moves left and right.

[0023] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
