[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0032] During the start-up and shutdown of the unit, some valves (drain valves or exhaust valves) are left open or leak internally, or during normal operation, some valves are mistakenly opened or leak internally, resulting in partial steam loss, heat loss, increased coal consumption, and reduced unit efficiency. At present, whether the valve is closed or open can only be checked on-site based on the experience of the staff, and the temperature is measured with a temperature measuring gun. However, due to the complex on-site pipelines, it is not easy to find internal leakage or mistaken opening of the valve. If there is a water leak, and the water leak is not very obvious, it is not easy for the staff to observe.

[0033] For this reason, please see Figures 1 to 3 The utility model provides a hydrophobic internal leakage monitoring device 100, which is intended to help staff quickly determine whether a valve 2 is missing or leaking internally.

[0034] The utility model discloses a hydrophobic internal leakage monitoring device 100, comprising a pipeline 1, a valve 2 and a temperature indicating component 3, wherein the pipeline 1 is formed with a circulation channel 11 for the flow of a heat medium, and an installation card connected to the circulation channel 11 is provided on the outer wall of the pipeline 1; the valve 2 is arranged on the pipeline 1 and is located upstream of the installation card along the flow direction of the heat medium; the temperature indicating component 3 comprises a heat conducting pipe 31 and a temperature-sensitive color changing portion 32, wherein at least a part of the structure of the heat conducting pipe 31 is passed through the installation card and extends into the pipeline to be connected with the circulation channel 11; the temperature-sensitive color changing portion 32 is accommodated in the heat conducting pipe 31.

[0035] The utility model provides a device for detecting internal leakage of hydrophobic water, wherein a temperature indicating device is installed at the outlet of the valve 2 or the outlet of the exhaust valve 2, and the temperature indicating function of the temperature-sensitive color-changing portion 32 that can change color according to the temperature is utilized to help the staff to quickly determine whether the valve 2 is leaking or not, thereby preventing the additional loss of hydrophobic water or steam.

[0036] In order to prevent heat or steam from being lost through the heat pipe 31, in one embodiment of the present application, the temperature indicating assembly 3 also includes a transparent cover 33, which is connected to the end of the heat pipe 31 away from the pipeline 1 to seal the heat pipe 31. The transparent cover 33 not only facilitates the staff to observe the color change of the temperature-sensitive color-changing portion 32 in the heat pipe 31 from the outside, but also plays a certain sealing role, reducing heat loss or preventing steam from overflowing.

[0037] To facilitate the installation of the transparent cover 33, in one embodiment of the present application, the temperature indicating assembly 3 also includes a heat-conducting ring plate 34, one side of the heat-conducting ring plate 34 covers the end of the heat-conducting tube 31 away from the pipeline 1 and is sealed and connected to the port of the heat-conducting tube 31, and the outer peripheral side wall of the heat-conducting ring plate 34 is provided with a threaded groove; the temperature-sensitive color-changing portion 32 is placed on the side of the heat-conducting ring plate away from the heat-conducting tube 31; the transparent cover 33 is screwed to the heat-conducting ring plate 34 through the threaded groove, and the heat-conducting ring plate 34 is fixed to the heat-conducting tube 31 by bonding or welding, so that the transparent cover 33 can be tightened by the threaded structure. In addition, when the temperature-sensitive color-changing portion 32 needs to be replaced or repaired, the transparent cover 33 can be directly uncovered, and the structure is simple and easy to operate.

[0038] To further prevent heat loss, in one embodiment of the present application, the transparent cover 33 is a vacuum glass cover. Vacuum glass is a double-layer structure with a vacuum layer formed between two layers of glass. The structure has low thermal conductivity and can provide excellent heat insulation effect.

[0039] Of course, considering that the temperature-sensitive color-changing portion 32 requires certain temperature conditions when realizing the temperature indication function, when the temperature-sensitive color-changing portion 32 is placed outside the circulation channel 11, due to the heat conduction performance of the heat pipe 31, part of the heat will be lost through the heat pipe 31, and the heat reaching the temperature-sensitive color-changing portion 32 may not be able to change the color of the temperature-sensitive color-changing portion 32, thereby reducing the temperature indication accuracy of the temperature indication component 3. In order to solve the above problem, in one embodiment of the present application, the temperature indication component 3 also includes a transparent sleeve 35, which is transparent. The transparent sleeve 35 can be movably inserted into the heat-conducting tube 31 through the port of the heat-conducting tube 31 at one end away from the pipeline 1, and the temperature-sensitive color-changing part 32 is contained in the transparent sleeve 35; wherein, the temperature-indicating component 3 has a specific detection state and a display state. In the detection state, part of the structure of the transparent sleeve 35 is contained in the circulation channel 11 and the temperature-sensitive color-changing part 32 is contained in the circulation channel 11; in the display state, part of the structure of the transparent sleeve 35 reveals the heat-conducting tube 31 and the temperature-sensitive color-changing part 32 reveals the heat-conducting tube 31. In this way, when the staff needs to judge whether the valve 2 is missing or leaking, the transparent sleeve 35 can be pushed into the circulation channel 11 so that the temperature-sensitive color-changing part 32 can be extended into the pipeline 1. After maintaining the detection state for a period of time, the transparent sleeve 35 is pulled out, and the condition of the valve 2 can be accurately judged according to the color change of the temperature-sensitive color-changing part 32.

[0040] To avoid heat loss, in one embodiment of the present application, the temperature indicating assembly 3 further includes a sealing sleeve 36, which is accommodated in the heat conducting tube 31 and is used to fill the gap between the heat conducting tube 31 and the transparent sleeve 35. The sealing sleeve 36 is generally made of a rubber material or plastic with soft elasticity and good wear resistance, so that when the transparent sleeve 35 is impacted, vibrated or pressed during its movement, it can absorb energy and reduce the impact force transmitted to the heat conducting tube 31, so as to extend the service life of the heat conducting tube 31 and the transparent sleeve 35.

[0041] In order to facilitate the staff to hold the transparent sleeve 35, in one embodiment of the present application, a handle 37 is provided at one end of the transparent sleeve 35 away from the heat conducting pipe.

[0042] In order to prevent the handle 37 from being overheated and scalding people, in one embodiment of the present application, the outer side of the handle 37 is wrapped with a heat-insulating material, and the heat-insulating material can be heat-insulating rubber or heat-insulating asbestos.

[0043] For the purpose of facilitating production, in one embodiment of the present application, the temperature-sensitive color-changing portion 32 is a color-changing plate 321, and the outer wall of the color-changing plate 321 is covered with a temperature-changing material, which can be a color-changing paint or coating. In other embodiments, the temperature-sensitive color-changing portion 32 can also be a shape memory alloy, such as a nickel-titanium alloy, which can be pressed into a shape at low temperatures, but will return to its original shape when heated. The temperature indication function is achieved by judging the degree of deformation of the shape memory alloy, but this is relatively costly and is not used as a preferred solution.

[0044] The present application also provides a pipeline 1 system, including a hydrophobic internal leakage monitoring device 100, wherein the specific structure and specific installation method of the hydrophobic internal leakage monitoring device 100 refer to the above-mentioned embodiment. Since the pipeline 1 system adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which are not described one by one here.

[0045] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
