Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and in particular relates to a hydrophobic flange for preventing water from accumulating in a sight glass. Background Art

[0002] There are many piping systems on ships. In the return pipes of some piping systems, sight glasses made of tempered glass are installed. Through the sight glasses, the flow of liquid, gas, steam and other media in the pipelines can be observed at any time, such as the turbidity of the media, and the flow rate of the media can be measured and reflected. This is crucial to ensure the safe operation of the ship system. The sight glasses can promptly detect abnormal conditions in the pipelines, such as blockages, leakages or changes in the properties of the media, so that corresponding maintenance or repair measures can be taken.

[0003] However, due to the system principle and the need for pipeline layout, some sight glasses will inevitably be set up outdoors, and for the convenience of observation, the sight glasses are often placed upward on the lower flange welded on the pipe wall and fastened between the upper and lower flanges by bolt fasteners. Figure 1 As shown, since the sight glass is installed upward, rainwater will accumulate at the sight glass and the enclosure position of the upper flange during precipitation, which will affect the observation effect of the sight glass and make it difficult for operators to monitor the flow conditions inside the pipeline. In addition, long-term water storage will accelerate the corrosion process of the sight glass and the flange, making it more likely to form rust. Especially for steel components, rust will shorten the service life of the components and may cause an increase in the maintenance cost of the pipeline system, and even affect the structural integrity of the pipeline system.

[0007] As a preferred technical solution, the number of the hydrophobic grooves is determined according to the size of the inner edge of the flange body that contacts the sight glass.

[0008] Further, the lower end surface of the flange body is provided with a concentric annular sealing convex, and the water drainage groove is opened on the annular sealing convex and penetrates the inner and outer side surfaces of the annular sealing convex.

[0009] As a further preferred technical solution, the lower end surface of the flange body is further provided with a positioning flow guide, which is L-shaped and includes a vertical pipe and a horizontal pipe, the vertical pipe is communicated with the water drainage groove, and the part of the water drainage groove outside the sight mirror is surrounded in the vertical pipe, an arc-shaped cutout is opened on the pipe wall of the vertical pipe to position the sight mirror and fit the outer side surface of the sight mirror, the arc-shaped cutout is towards the center of the flange body, and the arc center of the arc-shaped cutout is concentric with the center of the flange body.

[0010] Further, the horizontal pipe port is provided with a butt joint to connect a hose and communicate to a drain or a water pump.

[0011] Further, a detachable sealing plug is arranged at the port of the horizontal pipe.

The hydrophobic grooves 231 are opened on the lower end surface of the flange body 21 and connected to the inner edge of the flange body 21, and the hydrophobic grooves 231 are located between the flange bolt holes 22 to avoid affecting the stability of the clamping and fixing of the sight mirror 12. The distance from the farthest end of the hydrophobic groove 231 to the center of the flange body 21 is greater than the radius of the sight mirror 12, ensuring that the hydrophobic passage is unobstructed and the path is the shortest.

[0028] In this embodiment, a concentric annular sealing protrusion 23 is provided on the lower end face of the flange body 21 for clamping and fixing the sight mirror 12. The inner diameter of the annular sealing protrusion 23 is not larger than the inner diameter of the flange body 21, and the outer diameter of the annular sealing protrusion 23 is smaller than the outer diameter of the sight mirror 12, so that a sealing line is formed between the flange body 21 and the sight mirror 12. At the same time, the inner diameter of the circular ring where the flange bolt hole 22 is located is larger than the outer diameter of the sight mirror 12, thereby avoiding affecting the installation of the sight mirror 12; the hydrophobic groove 231 is opened on the annular sealing protrusion 23 and passes through the inner and outer side surfaces of the annular sealing protrusion 23, and can discharge rainwater accumulated in the sight mirror 12 while ensuring the clamping force. Specifically, the cross-section of the hydrophobic groove 231 is a semicircular hole with an opening facing the sight mirror 12, and the number of the semicircular holes is not more than four, and the semicircular holes are radially and evenly distributed on the inner edge of the flange body 21.

[0029] In a further preferred embodiment, the lower end surface of the flange body 21 is further provided with a positioning guide member, such as Figure 6As shown, the positioning flow guide is in L shape, including vertical pipe 241 and horizontal pipe 243, the vertical pipe 241 communicates with the water drain groove 231, and the part of the water drain groove 231 outside the sight mirror 12 is surrounded in the vertical pipe 241, the arc-shaped cutout 242 is formed on the pipe wall of the vertical pipe 241, the arc-shaped cutout 242 is towards the center of the flange body 21, and the center of the arc-shaped cutout 242 is concentric with the center of the flange body 21. In actual work, the arc-shaped cutout 242 can be used for auxiliary positioning when installing the sight mirror 12, by sticking the sight mirror 12 to the arc-shaped cutout 242, the center of the sight mirror 12 can be ensured to be aligned with the center of the flange, at this time, the flange bolt is passed through the flange bolt hole 22 of the flange body 21 and the lower flange 14 to be locked and fixed, so that the sight mirror 12 is fastened and clamped between the flange body 21 and the lower flange 14, the efficiency of installation and positioning is improved; at the same time, since the installed sight mirror 12 is stuck to the arc-shaped cutout 242, it can also ensure that the stored water 13 from the water drain groove 231 flows out from the horizontal pipe 243 port of the positioning flow guide, and plays a flow guiding role, the included angle between the horizontal pipe 243 and the vertical pipe 241 is obtuse, and the port of the horizontal pipe 243 is lower than the upper plane of the sight mirror 12, so that the discharge speed of the stored water 13 is improved.

[0030] Further, the port of the horizontal pipe 243 is provided with a connector for connecting a hose and being connected to a drain or a water pump, in daily work, by connecting the hose at the port of the horizontal pipe 243 and leading to the drain, the rainwater falling on the sight mirror 12 can be automatically discharged in a directional manner, avoiding that the stored water 13 of the sight mirror 12 affects observation, when there is more stored water 13 on the sight mirror 12 in bad weather, by connecting the hose at the port of the horizontal pipe 243 and connecting to the water pump, the discharge efficiency of the stored water 13 is improved, so that the sight mirror 12 can also be observed in time in bad weather, at the same time, by connecting the hose, the water pump can also be located in a safer position, ensuring the safety of equipment use, in addition, the port of the horizontal pipe 243 is provided with a detachable sealing plug, when the sight mirror 12 needs to be cleaned, by installing the sealing plug at the port of the horizontal pipe 243, the cleaning water can be saved while the detergent is soaked for descaling.
