High-temperature gasket with warning function

Abstract

The utility model discloses a high-temperature gasket with a warning function. The high-temperature gasket comprises a gasket body. A fixing groove is formed in the gasket body, a first annular block is connected to the inner wall of the fixing groove, a second annular block is connected to the inner wall of the fixing groove, and a temperature early warning device is arranged at the bottom end of the second annular block. According to the high-temperature gasket with the warning function, the temperature in the gasket body is detected through a temperature sensor in the temperature early warning device, and when the detected temperature reaches the preset temperature t1 (the temperature tolerance threshold value of the gasket body is t2, and the temperature value of t1 is lower than the temperature value of t2), an alarm is started to warn the gasket body. Due to the fact that the temperature of the gasket body continuously rises to deform after the alarm sounds, in the process that the temperature of t1 rises to t2, time can be reserved for a worker to process the gasket body, the situation that the gasket body deforms due to high temperature and influences pipeline sealing is avoided, and therefore the early warning effect is achieved on the gasket body with the temperature tolerance reaching the threshold value in the high-temperature environment.

Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a high-temperature gasket with a warning function. Background Art

[0002] A gasket is a mechanical sealing element used between two objects. Its main purpose is to strengthen the seal and prevent fluid leakage. According to its material and structural characteristics, gaskets can be divided into three categories: non-metallic gaskets, metal gaskets, and metal-non-metallic combination gaskets. Among them, metal gaskets are suitable for environments with high temperature, high pressure and heavy loads.

[0003] Currently, when metal gaskets are used for high-temperature pipeline sealing, they are easily deformed due to thermal expansion in high temperature environments, which affects the use of the gaskets. Workers are required to replace damaged gaskets in a timely manner. Workers cannot be notified in time when gaskets fail, which reduces their maintenance efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a high-temperature gasket with a warning function to solve the problem raised in the above-mentioned background technology that when the current metal gasket is used for high-temperature pipe sealing, the gasket is easily deformed due to thermal expansion in a high-temperature environment, thereby affecting the use effect of the gasket, and workers are required to replace the damaged gasket in time. Since the workers cannot be notified in time when the gasket fails, the maintenance efficiency of the workers is reduced.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature gasket with a warning function, comprising a gasket body;

[0006] A fixing groove is provided inside the gasket body, an annular block 1 is connected to the inner wall of the fixing groove, an annular block 2 is connected to the inner wall of the fixing groove, a temperature warning device is provided at the bottom of the annular block 2, heat dissipation grooves are provided at both the upper and lower ends of the gasket body, and a plurality of heat dissipation holes are equidistantly provided inside each of the heat dissipation grooves.

[0007] Preferably, the temperature warning device includes an alarm and a temperature sensor;

[0008] The alarm is installed at the bottom end of the annular block 2, and the alarm is electrically connected to a temperature sensor for detecting the internal temperature of the gasket body.

[0009] Preferably, an arc-shaped groove is formed on the outer wall of the gasket body.

[0010] Preferably, a plurality of support rods are equidistantly connected to the inner wall of the gasket body, and the plurality of support rods are distributed in a ring shape inside the fixing groove.

[0012] Preferably, a plurality of friction plates are equidistantly connected to the inner walls of the two heat dissipation grooves, and anti-slip patterns are provided on the surface of each friction plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The temperature sensor inside the temperature warning device detects the temperature inside the gasket body. When the detected temperature reaches the preset temperature t1 (the temperature tolerance threshold of the gasket body 1 is t2, and the temperature value of t1 is lower than the temperature value of t2), the alarm will be activated. Since the gasket body will continue to heat up and deform after the alarm sounds, during the process of the temperature rising from t1 to t2, time can be left for workers to come and process the gasket body, thereby avoiding the deformation of the gasket body due to high temperature and affecting the pipeline seal, and thus playing a warning role for the gasket body whose temperature tolerance reaches the threshold in a high-temperature environment;

[0015] 2. Under the action of the first annular block and the second annular block, it can play a supporting role inside the gasket body. By providing a plurality of support rods, and the plurality of support rods are annularly distributed inside the gasket body, the overall strength of the gasket body can be improved, and the deformation of the gasket body caused by extrusion can be reduced;

[0016] 3. By providing heat dissipation holes, the heat inside the gasket body flows out through the plurality of heat dissipation holes, reducing the accumulation of heat and lowering the temperature of the gasket body. Through the setting of the arc-shaped grooves, the heat conduction on the gasket body is smoother, reducing the obstruction during the heat conduction process, thereby accelerating the heat dissipation and greatly improving the use effect and practicability of the gasket body.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: a high-temperature gasket with a warning function, including a gasket body 1;

[0025] A fixed groove 2 is opened inside the gasket body 1. The inner wall of the fixed groove 2 is connected with a first annular block 3, and the inner wall of the fixed groove 2 is connected with a second annular block 4. A temperature warning device 5 is arranged at the bottom end of the second annular block 4. Heat dissipation grooves 6 are opened at both the upper and lower ends of the gasket body 1, and a plurality of heat dissipation holes 7 are equidistantly opened inside each heat dissipation groove 6; the temperature inside the gasket body 1 is detected by the temperature sensor inside the temperature warning device 5. When the detected temperature reaches the preset temperature t1 (the temperature tolerance threshold of the gasket body 1 is t2, and the temperature value of t1 is lower than the temperature value of t2), the alarm will be activated. Since the gasket body 1 will continue to heat up and deform after the alarm sounds, during the process of heating from t1 to t2, time can be left for workers to come and process the gasket body 1, thereby avoiding the deformation of the gasket body 1 due to high temperature and affecting the pipeline seal, and thus playing a warning role for the gasket body 1 whose temperature tolerance reaches the threshold in a high-temperature environment.

[0026] The temperature warning device 5 includes an alarm and a temperature sensor;

[0027] The alarm is installed at the bottom end of the second annular block 4, and the alarm is electrically connected to a temperature sensor for detecting the temperature inside the gasket body 1.

[0028] An arc-shaped groove 10 is opened on the outer wall of the gasket body 1; through the setting of the arc-shaped groove 10, the heat conduction on the gasket body 1 is smoother, reducing the obstruction during the heat conduction process, thereby accelerating the heat dissipation.

[0029] A plurality of support rods 9 are equidistantly connected to the inner wall of the gasket body 1, and the plurality of support rods 9 are annularly distributed inside the fixed groove 2; by arranging a plurality of support rods 9, the overall strength of the gasket body 1 can be improved, and the deformation of the gasket body 1 caused by extrusion can be reduced.

[0030] Each support rod 9 is internally provided with a water storage tank 11, and each water storage tank 11 is filled with distilled water; the distilled water provided inside the water storage tank 11 can absorb the heat generated by the gasket body 1, thereby accelerating the heat dissipation efficiency.

[0031] A plurality of friction plates 8 are equidistantly connected to the inner walls of the two heat dissipation grooves 6, and anti-slip lines are provided on the surface of each friction plate 8; through the arrangement of the friction plates 8, the friction force between the upper and lower surfaces of the gasket body 1 and the pipeline can be increased, thereby improving the connection tightness between the gasket and the pipeline.

[0032] Working principle: The gasket body 1 works in a high-temperature environment. When the temperature of the gasket body 1 is too high, the temperature sensor inside the temperature warning device 5 detects the temperature inside the gasket body 1. When the detected temperature reaches the preset temperature t1 (the temperature tolerance threshold of the gasket body 1 is t2, and the temperature value of t1 is lower than the temperature value of t2), the alarm will be activated. Since the gasket body 1 will continue to heat up and deform after the alarm sounds, during the process of the temperature rising from t1 to t2, time can be left for workers to come and process the gasket body 1, thereby avoiding the deformation of the gasket body 1 due to high temperature affecting the pipeline seal, and thus playing a warning role for the gasket body 1 whose temperature tolerance reaches the threshold in a high-temperature environment;

[0033] Under the action of the first annular block 3 and the second annular block 4, the inside of the gasket body 1 can be supported. By providing a plurality of support rods 9, and the plurality of support rods are annularly distributed inside the gasket body 1, the overall strength of the gasket body 1 can be improved, and the deformation of the gasket body 1 caused by extrusion can be reduced;

[0034] The heat inside the gasket body 1 flows out through the plurality of heat dissipation holes 7, reducing the accumulation of heat, lowering the temperature of the fixing groove 2 inside the gasket body 1. Through the water storage tank 11 inside the support rod 9, the distilled water inside the water storage tank 11 can absorb the heat generated by the gasket body 1, thereby accelerating the heat dissipation efficiency of the gasket body 1. Through the arrangement of the arc-shaped groove 10, the heat conduction on the gasket body 1 is made smoother, reducing the obstruction during the heat conduction process, thereby accelerating the heat dissipation. Through the arrangement of the fixing groove 2 and the heat dissipation groove 6, the overall thickness of the gasket body 1 is reduced, thereby enhancing the heat dissipation effect. Through the arrangement of the friction plates 8, the friction force between the upper and lower surfaces of the gasket body 1 and the pipeline can be increased, thereby improving the connection tightness between the gasket and the pipeline.

[0035] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
