Technical Field

[0001] The utility model belongs to the technical field of adapters, and in particular relates to an explosion-proof pipe adapter. Background Art

[0002] Pipe adapters are connecting tools between pipes and play an indispensable role in pipeline connection. There are many types of pipe adapters. Commonly used pipe joints can generally be divided into two types: hard pipe joints and hose joints. If classified according to the connection method between the pipe joints and the pipes, hard pipe joints include flared type, ferrule type and welding type, while hose joints are mainly crimped hose joints.

[0003] There are two types of pipe adapters: straight pipe and curved pipe. Since the curved pipe needs to change the direction of water flow, it is subject to greater impact from the water flow during use and has greater internal pressure. Therefore, an explosion-proof device is required. The commonly used explosion-proof method is to thicken the adapter. This explosion-proof method results in a large amount of adapter consumables, and once it bursts, it cannot be protected, causing water to spray out. Utility Model Content

[0006] Furthermore, the first curved pipe, the first connecting pipe and the second connecting pipe are an integrated structure.

[0007] Furthermore, a reinforcement ring is fixedly connected to the outer wall of the first curved pipe, and there are a plurality of the reinforcement rings, which are evenly distributed.

[0008] Furthermore, the cross section of the reinforcement ring is triangular or semicircular, and the material of the reinforcement ring and the material of the first bent pipe are both polyethylene.

[0009] Furthermore, a threaded joint is embedded inside one end of the second connecting pipe.

[0010] Furthermore, the material of the threaded joint is brass or stainless steel.

[0011] Furthermore, one end of the first connecting tube and one end of the second connecting tube are both provided with grooves, and metal rings are embedded in the grooves.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the arrangement of the first elbow and the second elbow can improve the explosion-proof performance of the pipeline; a cavity is arranged between the first elbow and the second elbow to reduce the raw materials used in the production of the adapter; and after the first elbow bursts under pressure, a buffer space can be provided to avoid deformation of the inner tube body and squeezing of the outer tube body, causing deformation and bursting of the outer tube body, thereby improving the explosion-proof performance.

[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1-3 As shown, an explosion-proof pipe adapter comprises a pressure-resistant bent pipe 1 and a first connecting pipe 2, wherein the first connecting pipe 2 is fixedly connected to one end of the pressure-resistant bent pipe 1, and the other end of the pressure-resistant bent pipe 1 is fixedly connected to the second connecting pipe 3, the pressure-resistant bent pipe 1 comprises a first bent pipe 11, and the two ends of the first bent pipe 11 are respectively fixedly connected to one end of the first connecting pipe 2 and one end of the second connecting pipe 3, a second bent pipe 12 is arranged outside the first bent pipe 11, and the two ends of the second bent pipe 12 are respectively fixedly connected to the two ends of the outer wall of the first bent pipe 11, and a cavity 13 is formed between the outer wall of the first bent pipe 11 and the inner wall of the second bent pipe 12.

[0020] According to the above structure, one end of the pipe where water flows out during docking is fixedly connected to one end of the first connecting pipe 2, and one end of the pipe where water flows in is docked to one end of the second connecting pipe 3. When in use, water flows from the first connecting pipe 2 through the pressure-resistant bent pipe 1 to the second connecting pipe 3. The pressure-resistant bent pipe 1 adopts a double-layer design of the first bent pipe 11 and the second bent pipe 12. When in use, it can withstand higher pressure, thereby achieving an explosion-proof effect. A cavity 13 is provided between the first bent pipe 11 and the second bent pipe 12. While thickening the pressure-resistant bent pipe 1, the raw materials used in the production of the adapter can be reduced. Moreover, after the first bent pipe 11 bursts under pressure, a buffer space can be provided to avoid the first bent pipe 11 from deforming and squeezing the second bent pipe 12, causing the second bent pipe 12 to deform and burst, thereby improving the anti-explosion performance.

[0021] like Figure 1-3 As shown, the first curved pipe 11, the first connecting pipe 2 and the second connecting pipe 3 are an integrated structure.

[0022] According to the above structure, the integration of the first curved pipe 11, the first connecting pipe 2 and the second connecting pipe 3 can improve the connection strength and facilitate production.

[0023] like Figure 3 As shown, the outer wall of the first elbow 11 is fixedly connected with a reinforcement ring 14, there are several reinforcement rings 14, and the reinforcement rings 14 are evenly distributed. The cross-section of the reinforcement ring 14 is triangular or semicircular, and the material of the reinforcement ring 14 and the material of the first elbow 11 are both polyethylene.

[0024] According to the above structure, the provision of the reinforcing ring 14 can improve the strength of the first elbow 11 and reduce the risk of deformation of the first elbow 11 when impacted by water flow, thereby improving the explosion-proof performance of the first elbow 11.

[0025] like Figure 2 and 3 As shown, a threaded joint 32 is embedded inside one end of the second connecting tube 3. The material of the threaded joint 32 is brass or stainless steel. One end of the first connecting tube 2 and one end of the second connecting tube 3 are both provided with grooves, and a metal ring 33 is embedded inside the groove.

[0026] According to the above structure, during installation, the docking pipes or faucets and other equipment can be directly threadedly connected to the threaded joint 32 for easy docking. The setting of the metal ring 33 can strengthen the threaded joint 32 and the port of the first connecting pipe 2, thereby avoiding cracking of the threaded joint 32 and the port of the first connecting pipe 2.

[0027] The working principle of the utility model is as follows: when docking, one end of the water outlet of the pipe is fixedly connected with one end of the first connecting pipe 2, and one end of the water inlet of the pipe is docked with one end of the second connecting pipe 3. When in use, water flows from the first connecting pipe 2 to the second connecting pipe 3 through the pressure-resistant curved pipe 1. The pressure-resistant curved pipe 1 adopts a double-layer design of a first curved pipe 11 and a second curved pipe 12, which can withstand higher pressure when in use, thereby achieving an explosion-proof effect. A cavity 13 is provided between the first curved pipe 11 and the second curved pipe 12. While thickening the pressure-resistant curved pipe 1, the raw materials used in the production of the adapter can be reduced. Moreover, after the first curved pipe 11 bursts under pressure, a buffer space can be provided to prevent the first curved pipe 11 from being deformed and squeezed. The second bend pipe 12 causes the second bend pipe 12 to deform and burst, thereby improving the explosion resistance performance. The integration of the first bend pipe 11, the first connecting pipe 2 and the second connecting pipe 3 can improve the connection strength and facilitate production and manufacturing. The setting of the reinforcement ring 14 can improve the strength of the first bend pipe 11. When impacted by water flow, the risk of deformation of the first bend pipe 11 is reduced, thereby improving the explosion-proof performance of the first bend pipe 11. During installation, the docking pipe or faucet and other equipment can be directly threadedly connected to the threaded joint 32 for easy docking. The setting of the metal ring 33 can strengthen the threaded joint 32 and the port of the first connecting pipe 2, thereby avoiding cracking of the port of the threaded joint 32 and the first connecting pipe 2.
