Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dampers, in particular to a viscous damper for high-temperature environments. Background Art
[0002] With the continuous development of modern industry, the reliability and safety of equipment in high-temperature environments have become a matter of great concern. In such environments, the use of mechanical equipment often faces various challenges, among which the vibration control of conveying pipelines is a key issue. To solve this problem, viscous dampers have emerged.
[0003] In the prior art, when conveying materials through pipelines, the pipelines will vibrate. At this time, a viscous damper is needed to buffer the vibration generated by the pipelines. However, most viscous dampers are easily affected by the working environment due to their simple structure, which affects their use. For example, in high-temperature environments, the damping performance of viscous dampers will be severely affected, resulting in poor adaptability of viscous dampers in high-temperature environments and low practicality. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, due to being affected by high-temperature environments, the damping performance of the viscous damper will drop significantly during the use process, and thus a viscous damper for high-temperature environments is proposed.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A viscous damper for high-temperature environments, including a lower connecting plate, a lower housing is arranged at the top of the lower connecting plate, an upper connecting plate is arranged at the top of the lower housing, an upper housing is arranged at the bottom of the upper connecting plate, a plunger is arranged at the bottom of the upper connecting plate, an inner elastic body is fixedly sleeved on the outer surface of the plunger, and an outer elastic body is arranged inside the lower housing.
[0006] Preferably, an inner elastic body is arranged inside the outer elastic body.
[0007] Preferably, damping liquid is poured into the outer elastic body.
[0008] Preferably, the lower connecting plate and the upper connecting plate are horizontally arranged, and the lower housing, the upper housing and the plunger are vertically arranged.
[0009] Preferably, the outer surface of the upper end of the lower housing is arranged inside the upper housing, and the damping liquid has high viscosity.
[0010] Compared with the prior art, the advantages and positive effects of the utility model are as follows
[0011] 1. During the use of the present utility model, through the interaction of a series of components, when the viscous damper is installed and buffers and reduces the vibration generated by the pipeline, due to the influence of the ambient temperature, the temperatures of the lower housing, the upper connecting plate, and the plunger will increase accordingly. At this time, under the action of the outer elastic body and the inner elastic body, the outer elastic body can effectively isolate the high temperature transmitted from the lower housing. At the same time, under the action of the inner elastic body, it can effectively isolate the high temperature transmitted from the plunger, thereby preventing the damping liquid from generating high temperature and reducing its damping performance, and greatly improving the adaptability and practicality of the viscous damper under high temperature.
[0012] 2. During the use of the present utility model, through the interaction of a series of components, when the pipeline vibrates, under the action of the viscous damper, first, the vibration force generated by the pipeline will be transmitted to the upper connecting plate, and then the vibration force will be transmitted to the plunger and the inner elastic body through the upper connecting plate. At this time, the inner elastic body undergoes displacement and squeezes the outer elastic body and the damping liquid. The squeezed outer elastic body and damping liquid will deform and generate a reverse damping force on the inner elastic body and the plunger, thereby playing a role in buffering and reducing the pipeline vibration, preventing the pipeline from being damaged due to excessive vibration force, and further extending the service life of the pipeline.

[0017] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0018] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0019] Embodiment 1: As Figure 1 、 Figure 2As shown in the figure, the present utility model provides a viscous damper for high-temperature environments, which includes a lower connecting plate 1. A lower housing 3 is provided at the top of the lower connecting plate 1. An upper connecting plate 6 is provided at the top of the lower housing 3. An upper housing 5 is provided at the bottom of the upper connecting plate 6. A plunger 8 is provided at the bottom of the upper connecting plate 6. An inner elastic body 7 is fixedly sleeved on the outer surface wall of the plunger 8. An outer elastic body 4 is provided inside the lower housing 3. The inner elastic body 7 is provided inside the outer elastic body 4. A damping liquid 2 is filled inside the outer elastic body 4.
[0020] The effect achieved by the entire Embodiment 1 is that when the viscous damper is installed and buffers and reduces the vibration generated by the pipeline, due to the influence of the ambient temperature, the temperatures of the lower housing 3, the upper connecting plate 6, and the plunger 8 will increase accordingly. At this time, under the action of the outer elastic body 4 and the inner elastic body 7, the outer elastic body 4 can effectively isolate the high temperature transmitted from the lower housing 3. At the same time, under the action of the inner elastic body 7, it can effectively isolate the high temperature transmitted from the plunger 8, thereby preventing the damping liquid 2 from generating high temperature and reducing its damping performance, and greatly improving the adaptability and practicability of the viscous damper at high temperatures.
[0021] Embodiment 2: As Figure 1 , Figure 2 shown, the lower connecting plate 1 and the upper connecting plate 6 are horizontally arranged, the lower housing 3, the upper housing 5, and the plunger 8 are all vertically arranged. The outer surface wall at the upper end of the lower housing 3 is arranged inside the upper housing 5, and the damping liquid 2 has high viscosity.
[0022] The effect achieved by the entire Embodiment 2 is that when the viscous damper is in use, it first needs to be installed. The inner elastic body 7 is sleeved on the outer surface wall of the plunger 8, then the outer elastic body 4 is installed inside the lower housing 3, and then the damping liquid 2 is filled into the outer elastic body 4. Finally, the plunger 8 and the inner elastic body 7 are passed through the outer elastic body 4 through the upper connecting plate 6, thus completing the installation of the viscous damper. When the pipeline vibrates, under the action of the viscous damper, the vibration force generated by the pipeline will be transmitted to the upper connecting plate 6, and then the vibration force will be transmitted to the plunger 8 and the inner elastic body 7 through the upper connecting plate 6. At this time, the inner elastic body 7 displaces and squeezes the outer elastic body 4 and the damping liquid 2. The squeezed outer elastic body 4 and damping liquid 2 will deform and generate a reverse damping force on the inner elastic body 7 and the plunger 8, thereby buffering and reducing the vibration of the pipeline, preventing the vibration force from being too large and damaging the pipeline, and thus extending the service life of the pipeline. At the same time, when the viscous damper is in use, since the upper housing 5 is sleeved on the lower housing 3, it can play a good role in rain and dust protection when used in rainy weather, and the mutually cooperating outer elastic body 4 and inner elastic body 7 are flexible materials, which will form a good damping and vibration reduction effect by themselves, further improving the buffer and shock absorption effect on the pipeline.
[0023] Working principle: When in use, first, under the operation of the staff, the inner elastic body 7 is sleeved on the outer wall of the plunger 8, then the outer elastic body 4 is installed in the lower housing 3, and then the damping fluid 2 is filled into the outer elastic body 4. Finally, the plunger 8 and the inner elastic body 7 are inserted through the upper connecting plate 6 into the outer elastic body 4, thus completing the installation of the viscous damper. After the viscous damper is installed, under the operation of the staff, the pipeline is connected to the viscous damper through the pipe clamp accessory. During the use process, when the pipeline vibrates, under the action of the viscous damper, the vibration force generated by the pipeline will be transmitted to the upper connecting plate 6, and then the vibration force is transmitted to the plunger 8 and the inner elastic body 7 through the upper connecting plate 6. At this time, the inner elastic body 7 displaces and squeezes the outer elastic body 4 and the damping fluid 2. The squeezed outer elastic body 4 and damping fluid 2 will deform and generate a reverse damping force on the inner elastic body 7 and the plunger 8, thereby playing a role in buffering and reducing the vibration of the pipeline, avoiding damage to the pipeline caused by excessive vibration force. At the same time, under the action of the upper housing 5 and the lower housing 3, it can play a good role in rain and dust protection when used in rainy weather. When the viscous damper buffers and reduces the vibration of the pipeline, due to the influence of the ambient temperature, the temperatures of the lower housing 3, the upper connecting plate 6 and the plunger 8 will rise accordingly. At this time, under the action of the outer elastic body 4 and the inner elastic body 7, the outer elastic body 4 can effectively isolate the high temperature transmitted from the lower housing 3. At the same time, under the action of the inner elastic body 7, it can effectively isolate the high temperature transmitted from the plunger 8, thereby preventing the damping fluid 2 from generating high temperature and reducing its damping performance, greatly improving the adaptability and practicability of the viscous damper at high temperatures.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
