[0026] See Figs. 1-2The utility model provides a pipeline structure 100, through adding counterweight 20 on pipe fitting 10 to reduce the vibration of pipe fitting 10 in the working process, to improve the durability of pipe fitting 10, and counterweight 20 is made of stainless steel material or through powder metallurgy process or through casting process, is not easy to rust, is more durable and stable.
[0027] Pipeline structure 100 includes pipe fitting 10 and counterweight 20, and pipe fitting 10 includes straight pipe section 11 and elbow section 12, and straight pipe section 11 is connected with elbow section 12, and counterweight 20 is made of stainless steel material or through powder metallurgy process or casting process, and counterweight 20 is provided with clamping groove 21, and the outer peripheral wall of pipe fitting 10 is clamped in clamping groove 21.
[0028] Thus, pipe fitting 10 is used to communicate with compressor, and the vibration of compressor in the working process can be transmitted to pipe fitting 10, counterweight 20 is connected with pipe fitting 10, and pipe fitting 10 can drive counterweight 20 to vibrate synchronously when vibrating, and counterweight 20 changes the original vibration frequency by using the weight of installation position, destroys the resonance of installation position, and reduces the vibration amplitude. In addition, counterweight 20 is made of stainless steel material or through powder metallurgy process or casting process, and is not easy to rust, and is more durable and stable. Counterweight 20 is connected with pipe fitting 10 through clamping groove 21, and the structure is simple, stable in installation and convenient to disassemble and assemble.
[0029] Need to explain, when counterweight 20 is made of stainless steel material, it can realize the technical effect of not rusting. When counterweight 20 is made of powder metallurgy process or casting process, it is not limited to stainless steel material, and other materials can also reduce rust and be more durable.
[0030] Further, counterweight 20 is connected with elbow section 12, or counterweight 20 is connected with straight pipe section 11, and the distance between counterweight 20 and elbow section 12 is less than half of straight pipe section 11. Thus, since the vibration of elbow section 12 area is most violent in the working process of pipe fitting 10, counterweight 20 is installed close to elbow section 12, which can maximize the vibration of pipe fitting 10 and improve the damping effect.
[0031] Need to explain, here the length of straight pipe section 11 refers to the length of straight pipe section 11 when counterweight 20 is arranged on straight pipe section 11 and spaced apart from elbow section 12.
[0032] Further, in the embodiment, pipe fitting 10 includes a plurality of straight pipe sections 11 and elbow sections 12, and at least one counterweight 20 is arranged at each elbow section 12, so as to further improve the damping effect of counterweight 20 on pipe fitting 10.
[0033] It can be understood that in other embodiments, each of the pipe sections 10 can be provided with the counterweight 20.
[0034] Specifically, the straight pipe sections 11 and the bent pipe sections 12 of the pipe 10 are connected end to end and arranged in sequence, and thus each counterweight 20 is arranged spaced apart from the extension direction of the pipe 10, so that the pipe 10 is more balanced in force.
[0035] The clamping groove 21 extends from the outer peripheral side of the counterweight 20 towards the center of the counterweight 20. In this way, the pipe 10 can be installed closer to the center of gravity of the counterweight 20, so that the damping effect of the counterweight 20 is better. Moreover, the clamping groove 21 is provided on the outer edge of the counterweight 20, so that when the counterweight 20 is installed, the pipe 10 can be directly inserted into the counterweight 20 along the clamping groove 21, and the installation is more convenient.
[0036] It can be understood that in other embodiments, the clamping groove 21 can also be completely provided inside the counterweight 20 and arranged spaced apart from the outer edge of the counterweight 20, which can also be stably connected with the pipe 10, and is not limited to the above-mentioned embodiment of being provided on the outer edge of the counterweight 20.
[0037] Preferably, the counterweight 20 is provided in a disc structure, and the clamping groove 21 extends from the outer edge of the counterweight 20 towards the axis direction of the counterweight 20 along the radial direction of the counterweight 20. In this way, the counterweight of the pipe 10 in each direction is more balanced.
[0038] Exemplarily, the clamping groove 21 extends to the axis position of the counterweight 20, and the pipe 10 and the counterweight 20 are coaxially arranged. In this way, after the pipe 10 and the counterweight 20 are coaxially arranged, the distance from the pipe 10 to each position of the counterweight 20 is the same, and the counterweight force is more balanced.
[0039] Of course, in other embodiments, the counterweight 20 can also be provided in a triangular, rectangular or other polygonal structure, and is not limited to the above-mentioned disc structure.
[0040] The end of the clamping groove 21 away from the outer edge of the counterweight 20 is provided in a circular arc shape and is adapted to the outer peripheral wall of the pipe 10. In this way, the connection between the clamping groove 21 and the pipe 10 is more closely, and the connection strength between the counterweight 20 and the pipe 10 is improved.
[0041] Since the larger the diameter of the pipe 10 is, the larger the size volume is, the more intense the vibration is, therefore the size of the counterweight 20 needs to be increased synchronously, and the smaller the diameter of the pipe 10 is, the counterweight 20 needs to be reduced correspondingly, otherwise the normal work of the pipe 10 is affected, the pipe 10 bears too much load, and unnecessary material waste is caused.
[0042] The utility model also provides a refrigeration system, including the pipeline structure 100 as described above.
[0043] Compared with the prior art, the pipeline structure provided by the utility model reduces the vibration of the pipe 10 in the working process by adding the counterweight 20 on the pipe 10, thereby improving the durability of the pipe 10, and the counterweight 20 is made of stainless steel material or by powder metallurgy process, is not easy to rust, is more durable and stable.
[0044] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered that it is within the scope of the present application.
[0045] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it should not be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled in the art, on the premise of not departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
