In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present utility model.
Some valves (drain valve or exhaust valve) are not closed or leaked in the starting and stopping process of the unit, or some valves are opened by mistake or leaked in the normal operation process, so that part of steam is lost, heat is lost, coal consumption is increased, and unit efficiency is reduced. Whether the valve is closed or opened at present can only be checked on site according to the experience of a worker, and the valve is checked through temperature measurement of a temperature measuring gun. However, the on-site pipeline is complicated in staggering, the valve is inconvenient to find when the valve is leaked or opened by mistake, and workers cannot observe the valve conveniently when the water leakage condition is not obvious.
In view of this, referring to fig. 1 to 3, the present utility model provides a hydrophobic leak monitoring device 100, which is intended to help a worker to quickly determine whether a missing or leak condition occurs at the valve 2.
The utility model discloses a drainage inner leakage monitoring device 100, which comprises a pipeline 1, a valve 2 and a temperature indicating assembly 3, wherein a circulation channel 11 for flowing a heating medium is formed in the pipeline 1, an installation card communicated with the circulation channel 11 is arranged on the outer side wall of the pipeline 1, the valve 2 is arranged in the pipeline 1 and is positioned at the upstream of the installation card along the flowing direction of a heating medium, the temperature indicating assembly 3 comprises a heat conducting pipe 31 and a temperature-sensitive color changing part 32, at least part of the heat conducting pipe 31 penetrates through the installation card and stretches into the pipeline to be communicated with the circulation channel 11, and the temperature-sensitive color changing part 32 is accommodated in the heat conducting pipe 31.
According to the drain internal leakage detection device provided by the utility model, the temperature indicating device is additionally arranged at the outlet of the valve 2 or the outlet of the exhaust valve 2, and the temperature indicating effect of the temperature-sensitive color-changing part 32 capable of changing color according to temperature is utilized to enable staff to help the staff to quickly judge whether the situation of missing or internal leakage occurs at the valve 2, so that extra loss of drain water or steam is prevented.
In order to avoid heat or steam loss through the heat pipe 31, in an embodiment of the present application, the temperature indicating assembly 3 further includes a transparent cover 33, the transparent cover 33 is connected to an end of the heat pipe 31 far away from the pipeline 1 to seal the heat pipe 31, and the transparent cover 33 not only facilitates a worker to observe the color change of the temperature sensitive color change portion 32 in the heat pipe 31 from the outside, but also plays a certain role in sealing, so as to reduce heat loss or prevent steam from overflowing.
In order to facilitate the installation of the transparent cover 33, in an embodiment of the present application, the temperature indicating assembly 3 further includes a heat conducting ring plate 34, one side of the heat conducting ring plate 34 is covered on one end of the heat conducting pipe 31 far away from the pipeline 1 and is in sealing connection with a port of the heat conducting pipe 31, a thread groove is formed on the peripheral side wall of the heat conducting ring plate 34, the temperature sensitive color changing portion 32 is placed on one side of the heat conducting ring plate far away from the heat conducting pipe 31, the transparent cover 33 is in threaded connection with the heat conducting ring plate 34 through the thread groove, the heat conducting ring plate 34 can be fixedly connected with the heat conducting pipe 31 through an adhesion or welding mode, so that the transparent cover 33 can be screwed through a thread structure, and in addition, when the temperature sensitive color changing portion 32 needs to be replaced or overhauled, the transparent cover 33 can be directly uncovered, and the structure is simple and easy to operate.
To further avoid heat loss, in one embodiment of the present application, the transparent cover 33 is a vacuum glass cover. The vacuum glass has a double-layer structure with a vacuum layer formed between two layers of glass, and the structure has low heat conduction performance and can provide excellent heat insulation effect.
Of course, considering that a certain temperature condition is required when the temperature-sensitive color-changing portion 32 realizes the temperature indication effect, and when the temperature-sensitive color-changing portion 32 is placed outside the circulation channel 11, due to the heat conduction property of the heat conduction tube 31, part of heat can be lost through the heat conduction tube 31, 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, and the temperature indication precision of the temperature indication assembly 3 is reduced. So, when the staff needs to judge that the valve 2 is not closed and is leaked, the transparent sleeve 35 can be pushed into the circulation channel 11 to enable the temperature-sensitive color-changing part 32 to extend into the pipeline 1, and after the detection state is maintained for a period of time, the transparent sleeve 35 is pulled out, so that the condition of the valve 2 can be accurately judged according to the color-changing condition of the temperature-sensitive color-changing part 32.
In order to avoid heat loss, in an embodiment of the present application, the temperature indicating assembly 3 further includes a sealing sleeve 36, where the sealing sleeve 36 is accommodated in the heat conductive pipe 31, and is used to fill the gap between the heat conductive pipe 31 and the transparent sleeve 35. The sealing sleeve 36 is generally made of a rubber material or plastic having soft elasticity and good abrasion resistance, and can absorb energy and reduce impact force transferred to the heat conductive pipe 31 when being impacted, vibrated or pressed during the movement of the transparent sleeve 35, so as to prolong the service life of the heat conductive pipe 31 and the transparent sleeve 35.
In order to facilitate the grasping of the transparent sleeve 35 by a worker, in one embodiment of the present application, a handle 37 is provided at an end of the transparent sleeve 35 remote from the heat pipe.
In order to avoid scalding the person due to the excessive temperature of the handle 37, in an embodiment of the present application, the outside of the handle 37 is wrapped with a heat insulating material, which may be heat insulating rubber or heat insulating asbestos.
For convenience of production, in one embodiment of the present application, the temperature-sensitive color-changing portion 32 is a color-changing plate 321, and an outer side wall of the color-changing plate 321 is covered with a temperature-changing material, which may be color-changing paint or coating. In other embodiments, the temperature-sensitive color-changing portion 32 may be a shape memory alloy, such as nickel-titanium alloy, which is pressed into a shape at low temperature, but returns to its original shape when heated, and the temperature-indicating function is realized by determining the deformation degree of the shape memory alloy, but this is not preferable.
The application also provides a pipeline 1 system, which comprises the drainage inner leakage monitoring device 100, wherein the specific structure and the specific installation mode of the drainage inner leakage monitoring device 100 refer to the above embodiments, and as the pipeline 1 system adopts all the technical schemes of all the embodiments, the pipeline 1 system at least has all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted herein.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
