Description

Technical Field

[0001] This utility model relates to the field of sewage discharge devices, specifically to a medium-pressure detachable sewage discharge device. Background Technology

[0002] For many years, due to the lack of sewage pipes in civil medium-pressure substations and the limitations imposed by environmental factors within the community, sewage discharge has consistently failed to meet safety evaluation standards. Sewage discharge from civil medium-pressure substations has always been a difficult problem to maintain and manage. Traditional sewage discharge devices require welding and fixing, which cannot be quickly disassembled, resulting in high maintenance costs. Sewage discharge cannot be carried out normally, leading to various hidden dangers such as excessive pressure loss, ice blockage, and deterioration of pressure when the pressure regulator is shut down. Therefore, it is necessary to design a medium-pressure detachable sewage discharge device that can solve the problem of sewage discharge from civil medium-pressure substations. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide a medium-pressure detachable sewage discharge device, which can reduce the cost of pollutant disposal and transportation, simplify the sewage discharge operation of medium-pressure stations, and improve the efficiency of sewage discharge work.

[0004] According to the technical solution provided by the embodiments of this utility model, a medium-pressure detachable sewage discharge device includes an inlet pipe, the inlet pipe including a first galvanized steel pipe, a first steel plate and a first seamless steel pipe, the first steel plate being welded between the first seamless steel pipe and the first galvanized steel pipe, the diameter of the first galvanized steel pipe being smaller than the diameter of the first seamless steel pipe; and a first reinforcing rib, the first reinforcing rib being welded between the first steel plate and the first galvanized steel pipe;

[0005] An equal-diameter external connector is screwed between the inlet pipe and the outlet pipe. The outlet pipe includes a second galvanized steel pipe, a second steel plate, and a second seamless steel pipe. The second steel plate is welded between the second seamless steel pipe and the second galvanized steel pipe. One end of the equal-diameter external connector has a first internal thread that matches the first seamless steel pipe on its inner surface, and the other end of the equal-diameter external connector has a second internal thread that matches the second seamless steel pipe on its inner surface. The diameter of the second galvanized steel pipe is smaller than the diameter of the second seamless steel pipe. A second reinforcing rib is welded between the second steel plate and the second galvanized steel pipe. Both the first reinforcing rib and the second reinforcing rib have triangular cross-sections.

[0006] A reducing internal thread connector is screwed between the first galvanized steel pipe and the filter pipe. A cap is screwed to the other end of the filter pipe. One end of the reducing internal thread connector has a third internal thread that matches the first galvanized steel pipe, and the other end has a fourth internal thread that matches the filter pipe. The reducing internal thread connector, the cap, and the filter pipe are all located inside the second seamless steel pipe. The diameter of the filter pipe is larger than the diameter of the first galvanized steel pipe. The left end of the reducing internal thread connector is flush with the left end of the second seamless steel pipe. The length of the filter pipe is shorter than the length of the second seamless steel pipe, and the surface of the filter pipe has openings spaced apart.

[0007] In summary, the beneficial effects of this utility model are as follows:

[0008] 1. The easily detachable filter tube facilitates pollutant collection and ensures compliant sewage discharge operations;

[0009] 2. The connection uses quick connectors, which facilitates sewage discharge operations and improves sewage discharge efficiency;

[0010] 3. After the sewage discharge is completed, the conduit will be removed without affecting the operation in the process area;

[0011] 4. Simple structure, low cost, and no need to modify existing equipment in the station area;

[0012] 5. This enables the normal operation of sewage discharge at civil medium-pressure stations, reduces the occurrence of potential regulator failures caused by pollutants, and improves the level of safe and stable gas supply. Attached Figure Description

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A medium-pressure detachable sewage discharge device includes an inlet pipe 1, which comprises a first galvanized steel pipe 7, a first steel plate 8, and a first seamless steel pipe 9, wherein the first steel plate 8 is welded between the first seamless steel pipe 9 and the first galvanized steel pipe 7; a first reinforcing rib 10, which is welded between the first steel plate 8 and the first galvanized steel pipe 7; an equal-diameter external connector 2, which is screwed between the inlet pipe 1 and the outlet pipe 4, wherein the outlet pipe 4 comprises a second galvanized steel pipe 11, a second steel plate 12, and a second seamless steel pipe 13, wherein the second steel plate 12 is welded between the second seamless steel pipe 13 and the second galvanized steel pipe 11; a second reinforcing rib 14, which is welded between the second steel plate 12 and the second galvanized steel pipe 11; and a reducing internal thread connector 3, which is screwed between the first galvanized steel pipe 7 and a filter pipe 6, wherein a pipe cap 5 is screwed to the other end of the filter pipe 6.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the inner surface of one end of the equal-diameter external connector 2 is provided with a first internal thread that mates with the first seamless steel pipe 9, and the inner surface of the other end of the equal-diameter external connector 2 is provided with a second internal thread that mates with the second seamless steel pipe 13, facilitating the screw connection between the first seamless steel pipe 9 and the equal-diameter external connector 2, and between the second seamless steel pipe 13 and the equal-diameter external connector 2. The diameter of the first galvanized steel pipe 7 is smaller than the diameter of the first seamless steel pipe 9, and the diameter of the second galvanized steel pipe 11 is smaller than the diameter of the second seamless steel pipe 13.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the reducing internal thread connector 3, the pipe cap 5, and the filter tube 6 are all located inside the second seamless steel pipe 13. The diameter of the filter tube 6 is larger than the diameter of the first galvanized steel pipe 7. One end of the reducing internal thread connector 3 has a third internal thread that matches the first galvanized steel pipe 7, facilitating the screw connection between the first galvanized steel pipe 7 and the reducing internal thread connector 3.

The surface of the filter pipe 6 is provided with spaced openings.

[0025] In use: When the medium-pressure station needs to discharge sewage, first use the F-type quick connector to connect the conduit between the sewage valve and the first galvanized steel pipe 7, and then use the F-type quick connector to connect the second galvanized steel pipe 11 to the sewage discharge pipeline outside the station. After opening the sewage discharge, the pollutants are transferred into the filter pipe 6 after being intercepted by the filter pipe 6. The cleaner gas is discharged through the sewage discharge pipeline outside the station. After the sewage discharge is completed, separate the second galvanized steel pipe 11 from the sewage discharge pipeline outside the station, then separate the equal-diameter external connector 2 from the outlet pipe 4, and unscrew the filter pipe 6 to collect the solid and liquid pollutants in the filter pipe 6 for disposal at a designated location. This can reduce the cost of pollutant disposal and transportation, simplify the sewage discharge operation of the medium-pressure station, and improve the efficiency of the sewage discharge work. After the sewage discharge is completed, the conduit is removed without affecting the operation of the medium-pressure station. The structure is simple, the cost is low, and there are no requirements for modification of the existing equipment in the station area.
