Technical Field

[0001] This utility model belongs to the field of natural gas compressor technology, and in particular relates to a natural gas compressor intake pressure reduction structure. Background Technology

[0002] Natural gas compressors, as key equipment in the energy industry chain, are mainly used to compress methane gas to meet the needs of transportation, storage, and processes. Their applications cover multiple core scenarios and are designed with specific technologies. The following will explain their application areas, technical characteristics, corporate cases, and market position. The functions of natural gas compressors need to match the pressure, flow rate, and safety requirements of different scenarios. The main application areas include: Natural gas extraction and gathering: Pressurizing low-pressure natural gas at the wellhead or gathering station to facilitate its collection to processing plants or gas pipelines; providing pressure support before and after desulfurization and dehydration processes in processing plants; Long-distance pipelines and gas storage: Serving as trunk / branch line compressors to maintain pipeline gas transmission pressure, or achieving pressure regulation during gas injection and extraction in gas storage facilities; used for power generation, purification, or injection into the pipeline network, combining energy utilization and environmental protection value.

[0003] Natural gas compressors use pressure reducing valves to reduce the pressure in their intake pipes, adjusting the intake pressure to match actual application requirements. The pressure reducing valve has an exhaust port on its surface. When the internal pressure of the pressure reducing valve reaches a certain value, some pressure is released through the exhaust port to ensure equipment safety. The exhaust port of the pressure reducing valve is equipped with a barrier net to prevent foreign objects from entering and blocking the exhaust port. Because the exhaust port of the pressure reducing valve is affected by wind direction in windy weather, the direction of the pressure relief port must be consistent with the prevailing wind direction to prevent exhaust from accumulating due to headwinds. Therefore, a natural gas compressor intake pressure reducing structure is needed to protect the pressure relief port from blockage while simultaneously guiding and adjusting the exhaust to reduce the impact of wind direction on the exhaust from the pressure reducing valve. Utility Model Content

[0015] Example 2: Figure 1-6 This invention illustrates an embodiment of a natural gas compressor intake pressure reducing structure, comprising a pipe body 1; a pressure reducing valve 2 is connected to the right end of the pipe body 1, and a pipe body 3 is connected to the right end of the pressure reducing valve 2; an exhaust pipe 4 is connected to the surface of the pressure reducing valve 2; a grid frame 5 is fixedly installed on the left end of the exhaust pipe 4 via a flange; multiple rotating rods 6 are rotatably connected to the inner wall of the grid frame 5; a guide grid 7 is fixedly connected to the surface of the rotating rods 6; a rectangular box 8 is welded to the top of the grid frame 5; a frame plate 9 is provided above the grid frame 5; the rotating rods 6 are fixedly connected to the frame plate 9; a side plate 10 is fixedly connected to the surface of the rotating rods 6; and a connecting rod is rotatably connected to the surfaces of the multiple side plates 10 via a rotating shaft. 11.

[0017] In summary, the intake pressure reducing structure of this natural gas compressor, by moving the frame plate 9 with the pivot shaft 17, causes the frame plate 9 to drive the rotating rod 6 to rotate. At this time, with the cooperation of the side plate 10 and the connecting rod 11, multiple rotating rods 6 drive the guide grid plate 7 to swing at a suitable angle, which can achieve the purpose of preventing the pressure relief port from being blocked and guiding and adjusting the exhaust gas, so as to reduce the influence of the wind direction on the exhaust gas of the pressure reducing valve.
