Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection, in particular to a nut type pipeline connection device and a pipeline connection system. Background Art
[0002] In the field of pipeline connection, pipeline connectors are necessary structures to connect multiple pipelines to each other. In actual use, pipeline connectors are usually purchased in batches according to pipeline models, so the appearance of pipeline connectors connecting pipelines of the same model is almost exactly the same, and it is difficult to directly distinguish the type of material transported inside the pipeline itself. Therefore, in some devices that need to transport multiple materials, since the pipelines and pipeline connectors are exactly the same, it is difficult to directly judge the materials transported inside from the appearance. Usually, the pipeline connectors need to be disassembled, and the types of materials transported in different pipelines can be distinguished by the color of the internal sealing rings.
[0003] Take a gas water heater as an example. The gas water heater has a water supply pipeline and a gas pipeline. The existing method of distinguishing the water supply pipeline and the gas pipeline includes designing the sealing rings inside the pipe connectors connected to the water supply pipeline and the gas pipeline in different colors. However, this also requires the pipe connectors to be disassembled to distinguish the uses of different pipes, increasing maintenance costs and even causing material leakage. At the same time, since the appearance of the pipe connectors themselves is exactly the same, the installer cannot check whether the pipe connectors of the water supply pipeline and the gas pipeline are installed upside down during the installation process. Since the sealing rings for sealing water and gas are made of different materials, if they are used incorrectly or mixed, it will seriously affect the service life of the pipe connectors and bring safety hazards.
[0004] In view of this, the present utility model is proposed. Utility Model Content

[0030] The nut type pipe connection device 100 includes a sealing member 110 , a pressing member 120 , an identification member 130 and a nut 140 .
[0031] Please refer to Figure 2 , wherein the interior of the nut 140 is through-connected, and an internal thread 144 is provided on the inner surface of the internal nut 140. The two ends of the nut 140 are respectively a first connection end 141 and a second connection end 142. To facilitate installation and removal of the nut 140, a mounting portion 143 is further provided between the first connection end 141 and the second connection end 142, and the mounting portion 143 protrudes from the first connection end 141 and the second connection end 142.
[0032] In this embodiment, the outer surface of the mounting portion 143 is provided with a hexagonal mounting position, so as to facilitate the use of a wrench to install the nut 140. In other embodiments, the mounting portion 143 may also be other structures.
[0033] Furthermore, in order to facilitate the distinction between different nut-type pipe connection devices 100, an annular groove 1411 is provided on the outer surface of the first connection end 141 of the nut-type pipe connection device 100. The identification piece 130 is annular and is sleeved on the annular groove 1411. The identification piece 130 may be made of rubber or plastic, and the inner diameter of the identification piece 130 is slightly smaller than the diameter of the annular groove 1411 to ensure that the identification piece 130 can be stably sleeved on the annular groove 1411.
[0034] The outer surface of the identification member 130 is an identification area, which can be at least one of a color identification area, a shape identification area, or a pattern identification area. In this embodiment, the identification area is a color identification area, which can be made of colored materials, such as adding a colorant of a corresponding color to the raw materials of rubber or plastic, and then forming the mixture through a mold after melt blending.
[0035] In other embodiments, the identification area may also be a shape identification area, for example, the upper and lower sides of the arc surface of the identification element 130 are smooth curves, or the upper and lower sides of the arc surface of the identification element 130 are sawtooth curves.
[0036] In other embodiments, the identification area may also be a pattern identification area, for example, different patterns are formed on the outer surface of the identification piece 130, such as a water drop shape, flame shape, circle, triangle, diamond, or any other shape, so that the material in the corresponding pipeline can be identified by the pattern on the identification area.
[0037] The pattern on the identification area can be obtained by etching the same pattern on a mold, or by other methods.
[0038] Please refer to Figure 3 The internal thread 144 on the inner side of the nut 140 is arranged in the area corresponding to the first connecting end 141 and the mounting portion 143, and a clamping member limiting portion 145 is arranged in the area of the inner surface of the nut 140 corresponding to the second connecting end 142, and the clamping member 120 contacts and limits the clamping member limiting portion 145.
[0039] The clamping member limiting portion 145 is a slope whose diameter gradually increases along the direction from the second connection end 142 to the first connection end 141 ; both ends of the outer surface of the clamping member 120 are provided with slopes so that the clamping member 120 and the clamping member limiting portion 145 are in contact with each other.
[0040] The outer surface of the pressing member 120 contacts the inner surface of the nut 140, and the inclined surface is arranged corresponding to the pressing member stopper 145 inside the nut 140 to prevent the pressing member 120 from slipping out of the nut 140. When the nut 140 is fixed on the pipe body 200, the inner surface of the pressing member 120 is in close contact with the pipe body 200.
[0041] A sealing groove 210 is provided on the pipeline body 200 , the sealing member 110 is accommodated in the sealing groove 210 , and the pressing member 120 blocks the sealing groove 210 to prevent material leakage.
[0042] In this embodiment, the number of the sealing grooves 210 and the number of the sealing members 110 are both two, so as to improve the sealing effect.
[0043] The installation process and working principle of a nut type pipe connection device 100 provided in this embodiment are as follows:
[0044] First, put the red identification piece 130 on the annular groove 1411 of the first connecting end 141 of the nut 140, then install the seal 110 into the sealing groove 210 of the pipe body 200, and then cover the surfaces of the two seals 110 with the clamping piece 120, put the nut 140 on the surface of the clamping piece 120, and fit it with the thread of the connecting section of the pipe body 200, and finally complete the installation by limiting the clamping piece 120 and the clamping piece limiting part 145.
[0045] After the nut type pipe connection device 100 is installed, since the identification piece 130 is exposed, the material type in the pipe body 200 corresponding to the identification pieces 130 of different colors can be directly distinguished through the identification piece 130. At the same time, the exposed identification piece 130 can also be used to confirm whether the internal seal 110 is installed correctly, thereby avoiding the misuse or mixing of the seal 110, increasing the service life of the nut type pipe connection device 100, and avoiding the occurrence of safety hazards.
[0046] The present embodiment provides a nut-type pipe connection device 100 and a pipe connection system 10, in which an annular groove 1411 is provided on the outer surface of the nut 140, an identification piece 130 is accommodated in the annular groove 1411, and the identification piece 130 is distinguished by color, pattern and pattern, so that the types of materials transported in different pipes can be directly distinguished from the appearance, thereby improving the maintenance convenience of the staff. At the same time, since the identification piece 130 and the seal 110 can be checked for matching with each other during installation, the misuse and mixing of the seal 110 are avoided, the service life of the pipe connector is guaranteed, and the safety hazards caused by the mixing of the seal 110 are avoided.
