Description

Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a fire-fighting pipeline. Background Art

[0002] In recent years, with the continuous development of social economy, the scale of urban construction has been continuously expanded, and the number of buildings in various industries such as chemical industry and construction industry has been increasing, which has also brought new fire hazards. Firefighting pipelines refer to pipe materials used in firefighting, connecting firefighting equipment and instruments, and transporting fire-fighting water, gas or other media. The fire hazard level of clean rooms is divided into three categories: A, B and C. There are various types of chemical agents such as pharmaceutical preparations, raw materials and pharmaceutical excipients in the clean workshop of the pharmaceutical industry, and industrial manufacturing such as integrated circuit chips also uses various chemical reagents and special gases. According to the different raw materials, processing technology and auxiliary media required for production and manufacturing, combined with the characteristics of production and manufacturing, the fire hazard of clean workshops should be determined in accordance with the "Code for Fire Protection Design of Buildings" GB50016, and divided into four categories: A, B, C and D. When a fire occurs in a cleaning room, it may directly cause the explosion of gas medicine, expand the fire and cause serious disasters. There are many types of such devices on the market today. This utility model is specifically a fire-fighting pipe for a cleaning room. When a fire-fighting pipe is used in a cleaning room, the pipe needs to be extended to the required connection point. When connecting, due to ground friction and the twisting force of the pipe stretching, the threaded structure will become unstable, resulting in the possibility of water seepage at the connection position. Therefore, a clean room fire-fighting pipe that can be positioned and clamped is needed to further enhance the stability of the pipe connection. Utility Model Content

[0003] The purpose of the utility model is to provide a fire protection pipeline to solve the problems existing in the above-mentioned prior art.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A fire fighting pipe comprises a pipe, one end of the pipe is provided with a plug, the other end of the pipe is provided with an interface, the plug comprises a fixing ring and a first clamp, a side of the fixing ring close to the pipe is provided with a stepped circular tube, the first clamp is used to fix the pipe on the stepped circular tube, and the pipe is sleeved on the stepped circular tube;

[0006] The interface includes a neck flange and a second clamp, the second clamp is used to lock one end of the pipe on the neck of the neck flange, the inner wall of the neck flange is axially evenly provided with a plurality of receiving grooves at one end away from the pipe, the receiving grooves are provided with return springs and locking rods, the outside of the neck flange is screwed with a ring, the receiving groove is a through groove, the locking rod is connected to the inner wall of the ring through a steel rope, the inner wall of the neck flange is provided with a flexible dustproof sleeve near one end of the pipe, the diameter of the flexible dustproof sleeve gradually decreases along the axial direction, and the large diameter end of the flexible dustproof sleeve is fixedly connected to the inner wall of the neck flange.

[0007] By adopting the above technical solution, because the diameter of one end of the flexible dustproof sleeve is large and the diameter of the other end is small, the water flow will form a short convergence effect when passing through this place during use. The force applied to the flexible dustproof sleeve by the water flow can drive the interface to move away from the plug, and this movement is blocked by the locking rod, so the connection between the interface and the plug will be tighter under the action of this force. As the water pressure increases, this force will also increase, ensuring the sealing of the connection under high pressure, and rapid docking and disassembly can be achieved through plug-in connection, which is convenient for firefighting.

[0008] In a further embodiment, a plurality of spring angle irons are axially and evenly arranged on the outer wall of the flexible dustproof sleeve, one end of the spring angle iron is bonded and fixed to the outer wall of the flexible dustproof sleeve, and the other end of the spring angle iron is fixedly connected to the inner wall of the neck flange.

[0009] In a further embodiment, a retaining groove is provided on the inner wall of the neck flange, and a retaining spring is provided on the large diameter end of the flexible dustproof sleeve.

[0010] In a further embodiment, a plurality of water-permeable holes are densely and evenly spaced on the flexible dust-proof sleeve.

[0011] In a further embodiment,

[0012] A plurality of protrusions for resisting against a return spring are arranged inside the centrifugal end of the accommodating groove.

[0013] In a further embodiment, a limiting column is provided on a side of the spring angle iron facing away from the flexible dustproof sleeve.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. The diameter of the flexible dust-proof sleeve gradually decreases along the axial direction, and the large-diameter end of the flexible dust-proof sleeve is fixedly connected to the inner wall of the neck flange. Because one end of the flexible dust-proof sleeve has a large diameter and the other end has a small diameter, the water flow will form a short-term convergence effect when passing through this place when in use. The force applied to the flexible dust-proof sleeve by the water flow can drive the interface to move away from the plug, and this movement is blocked by the locking rod, so the connection between the interface and the plug will be tighter under the action of this force. As the water pressure increases, this force will also increase, thereby ensuring the sealing of the connection under high pressure, and rapid docking and disassembly can be achieved through plug-in connection, which is convenient for firefighting.
