Description

Technical Field

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

[0002] Natural gas compressors are key equipment in the natural gas industry. They are devices that increase the pressure and reduce the volume of natural gas through mechanical means. Their working principle is to use mechanical movement to reduce the volume of gas, thereby increasing the pressure. In the natural gas industry chain, they are used in the extraction, transportation, and storage of natural gas. For example, they provide power for long-distance pipeline transportation and pressurize natural gas for injection into gas storage facilities.

[0003] When a natural gas compressor is in use, issues such as excessive refrigerant, clogged outdoor unit condenser, and capacitor degradation in the outdoor unit fan, resulting in excessively low speed, can arise. To address this, when detecting refrigerant flow in the pipes, if the flow rate in the horizontal pipes is insufficient, the flow switch's monitoring probe may not detect it. Therefore, a refrigerant discharge structure for the natural gas compressor needs to be designed, featuring a retractable and adjustable monitoring probe that can flexibly adapt to situations where the refrigerant level in the horizontal pipes is insufficient. This ensures that the probe can still contact the medium even when the liquid level in the pipes is low, allowing the flow switch to stably monitor the refrigerant flow rate in the pipes. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerant discharge structure for a natural gas compressor, which can flexibly adapt to situations where the refrigerant level in the horizontal pipe is not full, ensuring that the medium can still be contacted even when the liquid level in the pipe is insufficient, and allowing the flow switch to stably monitor the refrigerant flow rate in the pipe, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A refrigerant discharge structure for a natural gas compressor includes a refrigerant connecting pipe connected to the compressor. A fixing member is fixedly connected to the top of the refrigerant connecting pipe. A locking tooth is provided on the top of the fixing member. A flow switch is provided on the top of the fixing member. The flow switch is located on the top of the locking tooth. A monitoring probe is fixedly installed at the bottom of the flow switch. A threaded sleeve is fixedly connected to the central axis of the surface of the monitoring probe. A limiting sleeve is threadedly connected to the surface of the threaded sleeve. A locking tooth is provided at the bottom of the limiting sleeve. The limiting sleeve contacts the top of the locking tooth. The locking tooth and the locking tooth engage. A fixing sleeve is fixedly connected to the bottom of the surface of the limiting sleeve. The flow switch penetrates to the bottom of the fixing member and the locking tooth and penetrates to the inner cavity of the refrigerant connecting pipe.

[0006] Preferably, a retaining ring is fixedly connected to the top of the fastener, and the retaining ring is fixedly connected to the bottom of the retaining tooth.

[0007] Preferably, the surface of the monitoring probe is covered with an installation sleeve, the inner cavity of the second locking tooth is fixedly connected with a connecting protrusion, and the installation sleeve is slidably connected to the connecting protrusion.

[0008] Preferably, the surface of the fixing sleeve is fixedly connected with multiple symmetrical throttles.

[0009] Preferably, the surface of the mounting sleeve is provided with a groove for the connecting protrusion to slide, and the monitoring probe is in contact with the refrigerant in the inner cavity of the refrigerant connecting pipe.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a flow switch to drive the monitoring probe through the inner cavity of the refrigerant connecting pipe to contact the liquid inside the refrigerant connecting pipe. Through the cooperation of the threaded sleeve, the limiting sleeve and the fixing sleeve, the limiting sleeve fixes and limits the monitoring probe. Finally, the position of the flow switch is fixed, which can flexibly adapt to the situation where the refrigerant in the horizontal pipe is not full, and ensure that the medium can still be contacted when the liquid level in the pipe is insufficient, so that the flow switch can stably monitor the refrigerant flow in the pipe.

[0012] 2. By using the mounting sleeve and the connecting protrusion together, the mounting sleeve guides the connecting protrusion when the second locking tooth slides on the surface of the mounting sleeve, ensuring that the sliding position of the second locking tooth on the surface of the mounting sleeve will not shift, thus improving the stability of the second locking tooth in vertical movement.

[0013] 3. By setting up a throttle, this utility model allows the throttle to apply force to the fixed sleeve when the fixed sleeve drives the limiting sleeve to rotate, making it convenient for the user to apply force to the limiting sleeve during the rotation process. Attached Figure Description

[0021] In the following description, embodiments of the refrigerant discharge structure of the natural gas compressor of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates a refrigerant discharge structure for a natural gas compressor according to an embodiment of the present invention. It includes a refrigerant connecting pipe 1 connected to the compressor. A fixing member 2 is fixedly connected to the top of the refrigerant connecting pipe 1. A locking tooth 4 is provided on the top of the fixing member 2. A fixing ring 3 is fixedly connected to the top of the fixing member 2, and the fixing ring 3 is fixedly connected to the bottom of the locking tooth 4. A flow switch 5 is provided on the top of the fixing member 2, located on the top of the locking tooth 4. A monitoring probe 6 is fixedly installed on the bottom of the flow switch 5. A threaded sleeve 7 is fixedly connected to the central axis of the surface of the monitoring probe 6. A limiting sleeve 8 is threadedly connected to the surface of the threaded sleeve 7. A locking tooth 10 is provided at the bottom of the limiting sleeve 8, and the limiting sleeve 8 contacts the top of the locking tooth 10. An installation sleeve 9 is sleeved on the surface of the monitoring probe 6. A connecting protrusion 11 is fixedly connected to the inner cavity of the locking tooth 10. The installation sleeve 9 is slidably connected to the connecting protrusion 11. The combined use of 1 and 2 allows the mounting sleeve 9 to guide the connecting protrusion 11 as the second locking tooth 10 slides on the surface of the mounting sleeve 9, ensuring that the sliding position of the second locking tooth 10 on the surface of the mounting sleeve 9 will not shift, thus improving the stability of the second locking tooth 10 in its up-and-down movement. The first locking tooth 4 engages with the second locking tooth 10. The bottom of the surface of the limiting sleeve 8 is fixedly connected to the fixing sleeve 12. The flow switch 5 passes through the bottom of the fixing part 2 and the first locking tooth 4 and through the inner cavity of the refrigerant connecting pipe 1. The surface of the fixing sleeve 12 is fixedly connected to multiple symmetrical handles 13. Through the setting of the handles 13, when the fixing sleeve 12 drives the limiting sleeve 8 to rotate, the handles 13 apply force to the fixing sleeve 12, which facilitates the user to apply force to the limiting sleeve 8 during the rotation process. The surface of the mounting sleeve 9 is provided with a groove for the connecting protrusion 11 to slide. The monitoring probe 6 is in contact with the refrigerant in the inner cavity of the refrigerant connecting pipe 1.

[0023] Working Principle: When using this invention, the user first inserts the flow switch 5 into the inner cavity of the refrigerant connecting pipe 1, allowing the monitoring probe 6 to contact the flowing refrigerant from the natural gas compressor inside the pipe, thus detecting the flow rate. Once the monitoring probe 6 contacts the flowing refrigerant, the downward adjustment of the monitoring probe 6 is stopped. During the downward movement of the monitoring probe 6, the locking tooth 10 drives the connecting protrusion 11 to slide downward within the groove of the mounting sleeve 9. When the locking tooth at the bottom of the locking tooth 10 engages with the locking tooth at the top of the locking tooth 4, the locking tooth 4 and the locking tooth 10 engage and limit the movement. This engagement structure effectively fixes the position of the monitoring probe 6, preventing displacement during the detection process. This ensures the accuracy and stability of the detection. Next, the user rotates the handle 13, which drives the limiting sleeve 8 to rotate on the surface of the threaded sleeve 7 through the fixed sleeve 12. The cooperation between the threaded sleeve 7 and the limiting sleeve 8 can further position the monitoring probe 6, so that the position of the monitoring probe 6 will not move when it passes through the inner cavity of the refrigerant connecting pipe 1. This dual positioning mechanism ensures that the monitoring probe 6 can remain stable during the detection process and improves the reliability of the detection results. Subsequently, when the monitoring probe 6 comes into contact with the refrigerant flow signal, it will transmit the signal to the flow switch 5. After receiving the signal, the flow switch 5 will process the data and display the processed data on its display screen.

[0024] In summary, this refrigerant discharge structure for a natural gas compressor, through the flow switch 5, drives the monitoring probe 6 to penetrate into the inner cavity of the refrigerant connecting pipe 1 and contact the liquid inside the refrigerant connecting pipe 1. The use of the threaded sleeve 7, the limiting sleeve 8, and the fixing sleeve 12 ensures that the limiting sleeve 8 fixes and limits the monitoring probe 6, thus fixing the position of the flow switch 5. This allows for flexible adaptation to situations where the refrigerant level in the transverse pipe is not full, ensuring that the flow switch can still contact the medium even when the liquid level in the pipe is insufficient, thus enabling stable monitoring of the refrigerant flow rate in the pipe.
