The amount of water was reduced a lot, but the pH value became very low, and corrosion was serious in many places, resulting in reduced durability of the pipe connection positions. There was still water flow, and the corrosion of the pipe by the water flow always existed. Therefore, a drain funnel was needed to discharge the water in the pipe outward.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In a specific embodiment, Figure 1-Figure 2 As shown, the basic working process of the drain funnel is disclosed;

[0029] The funnel body 1 and the reducer 2 fixedly mounted at the lower end of the funnel body 1;

[0030] A rotating sleeve 3 is rotatably mounted on the outer side of the lower end of the reducer 2 , and the outer sides of the funnel body 1 and the reducer 2 are coated with anti-rust paint 4 .

[0031] When using the gas pipe drain funnel that is easy to install and not prone to corrosion, it is necessary to first weld the upper end of the funnel body 1 to the gas pipe and fix the funnel body 1 to the lower end of the gas pipe. Then, the drain pipe can be connected to the lower end of the rotating sleeve 3. At this time, the gas inside the gas pipe can circulate. At the same time, the water flowing with the gas circulation will enter the interior of the funnel body 1 through the gas pipe and then be discharged through the drain pipe installed by the funnel body 1 and the rotating sleeve 3, thus completing the drainage process of the funnel.

[0032] In addition, the funnel body 1, the reducer 2 and the rotating sleeve 3 are made of aluminum alloy, which can effectively reduce the overlooking of the acidic water flow in the gas pipeline. At the same time, the outer sides of the funnel body 1 and the reducer 2 are coated with anti-rust paint, which can further reduce the corrosion effect of the funnel during use.

[0033] In one specific embodiment, Figures 1-6 As shown, the problem of backflow in the existing funnel drainage process is solved;

[0034] A fixing member 9 is fixedly installed inside the rotating sleeve 3, and a guide hole 14 is opened inside the fixing member 9, and the axis of the guide hole 14 is in the same straight line as the axis of the rotating sleeve 3;

[0035] A fixing rod 10 is fixedly installed inside the guide hole 14, and a fixing ring 11 is fixedly installed at one end of the fixing rod 10 away from the guide hole 14, and the fixing ring 11 is located at the center of the fixing member 9;

[0036] A sliding rod 12 is slidably mounted inside the fixing ring 11, and a sealing member 13 is fixedly mounted at the lower end of the sliding rod 12. The sealing member 13 is made of a hollow aluminum alloy.

[0037] The sealing member 13 is a truncated cone-shaped structure, and the sealing member 13 is sealedly connected to the fixing member 9 , and the fixing member 9 is located at the upper end of the main airbag ring 6 .

[0038] When using the gas pipe drain funnel which is easy to install and not prone to corrosion, water flows through the funnel body 1 into the interior of the reducer 2, and then into the interior of the rotating sleeve 3 through the reducer 2 and is discharged downward through the guide hole 14 opened in the middle of the fixing member 9. At this time, the water flows into the drain installed at the lower end of the rotating sleeve 3 and is discharged. In the process of water discharge, if the drain pipe is blocked,

[0039] Water will accumulate inside the drain pipe and cause the internal liquid level of the rotating sleeve 3 to rise. At this time, the seal 13 will move upward under the action of buoyancy after contacting the water liquid level, and the seal 13 will cause the sliding rod 12 to move upward inside the fixed ring 11. During the upward movement of the seal 13, it will contact the fixing part 9 and seal the guide hole 14. At this time, the liquid level of the drain pipe installed inside the rotating sleeve 3 can stop rising, avoiding the situation where water flows back into the gas pipeline, thereby ensuring the safety of the funnel.

[0040] Based on the above embodiments, Figure 1-Figure 2 and Figure 5-Figure 6 As shown, the problem of loose connection at the lower end of the existing funnel is solved;

[0041] A docking interface 5 is provided at the lower end of the rotating sleeve 3, and a main airbag ring 6 and a secondary airbag ring 7 are nested and installed inside the docking interface 5;

[0042] The main airbag ring 6 is located at the upper end of the auxiliary airbag ring 7, and the radius of the main airbag ring 6 is smaller than the radius of the auxiliary airbag ring 7, and the volume of the main airbag ring 6 is larger than the volume of the auxiliary airbag ring 7;

[0043] An air supply pipe 8 is fixedly installed on the outer side of the main airbag ring 6 , and one end of the air supply pipe 8 away from the main airbag ring 6 is fixedly connected to the auxiliary airbag ring 7 , and the auxiliary airbag ring 7 is connected to the main airbag ring 6 through the air supply pipe 8 .

[0044] When using this easy-to-install, corrosion-resistant gas pipeline drain funnel, the drain pipe needs to be docked with the docking interface 5 at the lower end of the rotating sleeve 3. During this process, the main airbag ring 6 and the auxiliary airbag ring 7 will contact the drain pipe and be squeezed by the drain pipe. After being squeezed, the main airbag ring 6 and the auxiliary airbag ring 7 will be deformed and fill the gap between the drain pipe and the rotating sleeve 3. In addition, gas will be transmitted between the main airbag ring 6 and the auxiliary airbag ring 7 through the gas pipe 8, which facilitates the main airbag ring 6 and the auxiliary airbag ring 7 to fill the gap, ensure the tightness of the connection between the rotating sleeve 3 and the drain pipe, and increase the overall practicality.

[0045] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
