[0001] The utility model belongs to the technical field of natural gas compressors, and particularly relates to a bursting disc pipeline fitting for a compressor. Background Technique

[0002] A natural gas compressor is an important device and is widely used in multiple fields such as natural gas extraction, processing, transportation, and storage. The following are some key information about natural gas compressors: Applications of natural gas compressors: Natural gas compressors are widely used in underground gas storage injection and production, natural gas external transmission pressurization, natural gas processing and refining, fuel gas pressurization, acid gas injection, biomass gas, coalbed methane gathering and transportation, CNG mother stations / standard stations / sub-stations, LNG liquefaction plants, refrigerant compression, and chemical industries; Types of natural gas compressors: According to the application category, natural gas compressors are mainly divided into the following major categories: booster compressors for natural gas long-distance pipelines, compressors for natural gas gathering and transportation, compressors for natural gas vehicle filling stations, high-pressure compressors for reinjection in upstream oil and gas fields, injection compressors for natural gas storage, feed gas compressors for liquefied natural gas, and BOG compressors supporting liquefied natural gas storage tank systems.

[0003] When a natural gas compressor is operating, the cylinder and packing need to be lubricated by the oil in the lubrication system. When the oil circuit of the lubrication system is blocked, the pressure of the entire oil circuit continuously rises until the pipeline or other fittings burst due to being unable to bear it, which will cause many unnecessary losses. Based on this, a bursting disc pipeline fitting for a compressor is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bursting disc pipeline fitting for a compressor with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] The bursting disc pipeline fitting for a compressor includes a mounting head, a filter screen is fixedly connected inside the mounting head, the top of the outer surface of the mounting head is threadedly connected with a first nut, a bursting disc is installed between the inner top of the first nut and the top of the mounting head, the bursting disc is hermetically connected with the first nut and the mounting head, a screw joint is fixedly connected to the top of the first nut, the outer surface of the screw joint is threadedly connected with a second nut, a collecting mechanism is fixedly connected to the top of the second nut, and a sealed sound-generating component is fixedly connected to the top of the collecting mechanism.

[0007] As a further optimized scheme of the utility model, the collecting mechanism includes a collecting pipe fixedly connected to the top of the second nut, a baffle is fixedly connected to the inner wall of the collecting pipe, the collecting pipe is made of a transparent material, and the baffle is arranged facing the top of the second nut.

[0008] As a further optimized solution of the utility model, the sealed sound - generating assembly includes a fixed pipe fixedly connected to the top of the collecting pipe. A sealing groove is provided at the inner top of the fixed pipe, and an exhaust hole is provided at the top of the fixed pipe. A sounding piece is fixedly connected in the exhaust hole. A fixed frame is fixedly connected to the bottom inner wall of the fixed pipe, and a connecting rod is slidably connected in the fixed frame.

[0012] The beneficial effect of the utility model lies in that: through the combined use of the mounting head, the first nut and the bursting disc, when the lubrication system oil circuit is blocked, the pressure of the whole oil circuit continuously rises, and then the pressure inside the mounting head rises. When the pressure rises to be about to reach the maximum pressure value of the whole oil circuit, the bursting disc ruptures, releasing the pressure of the whole oil circuit, preventing the pipelines and fittings in the lubrication system oil circuit from being damaged, thus effectively protecting the pipelines and fittings of the lubrication system and extending the service life of the pipelines and fittings.

[0019] Embodiment

[0020] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the bursting valve pipeline fitting for a compressor includes a mounting head 1. The bottom of the mounting head 1 is set as an inverted - table type, the top of the mounting head 1 is set as a cylindrical type, and the parts of the mounting head 1 set as cylindrical and inverted - table types are both provided with threads. The part of the mounting head 1 set as the inverted - table type is hermetically connected to the oil - circuit pipeline of the lubrication system through threads. A filter screen 2 is fixedly connected inside the mounting head 1. The top of the outer surface of the mounting head 1 is threadedly connected with a first nut 4. A bursting disc 3 is installed between the inner top of the first nut 4 and the top of the mounting head 1. The bursting disc 3 is hermetically connected to the first nut 4 and the mounting head 1. The top of the first nut 4 is fixedly connected with a screw joint 5. The outer surface of the screw joint 5 is threadedly connected with a second nut 6. The top of the second nut 6 is fixedly connected with a collection mechanism, and the top of the collection mechanism is fixedly connected with a sealing and sound - generating component.

[0021] When in use, first place the bursting disc 3 on the top of the mounting head 1, then thread the first nut 4 onto the part of the mounting head 1 set as the cylindrical type, and then the part of the mounting head 1 set as the inverted - table type can be threadedly connected to the oil - circuit pipeline of the compressor lubrication system. When the oil - circuit of the lubrication system is blocked, the pressure of the entire oil - circuit continuously rises, thereby causing the pressure inside the mounting head 1 to rise. When the pressure rises to be about to reach the maximum pressure value of the entire oil - circuit, the bursting disc 3 ruptures, releasing the pressure of the entire oil - circuit, preventing the pipelines and fittings in the oil - circuit of the lubrication system from being damaged, thus effectively protecting the pipelines and fittings of the lubrication system and extending the service life of the pipelines and fittings.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the collecting mechanism includes a collecting pipe 7 fixedly connected to the top of the second nut 6. A baffle 8 is fixedly connected to the inner wall of the collecting pipe 7. The collecting pipe 7 is made of a transparent material. The baffle 8 is arranged opposite to the top of the second nut 6. The sealed sound - generating assembly includes a fixed pipe 9 fixedly connected to the top of the collecting pipe 7. A sealing groove 10 is formed in the inner top of the fixed pipe 9. An exhaust hole 11 is formed in the top of the fixed pipe 9. A sounding piece 12 is fixedly connected in the exhaust hole 11. A fixed bracket 16 is fixedly connected to the bottom of the inner wall of the fixed pipe 9. A connecting rod 14 is slidably connected in the fixed bracket 16. Two ends of the connecting rod 14 are respectively fixedly connected with a floating ball 13 and a sealing plate 15. The sealing groove 10 and the exhaust hole 11 are internally connected. The sealing plate 15 is adapted to the sealing groove 10. The floating ball 13 is arranged directly above the baffle 8. The sealing plate 15 is located above the fixed bracket 16, and the floating ball 13 is located below the fixed bracket 16.

[0023] When the bursting disc 3 ruptures, the oil generated by releasing the pressure in the oil pipeline will enter the collecting pipe 7 through the screw joint 5 and the second nut 6. When entering the collecting pipe 7, the baffle 8 is provided to prevent the oil generated by releasing the pressure from being discharged into the external environment. As the oil in the collecting pipe 7 gradually increases, the floating ball 13 will move upward under the buoyancy of the oil. At the same time, the gas inside the collecting pipe 7 will enter the fixed pipe 9 and be discharged through the exhaust hole 11. During the process of the gas being discharged through the exhaust hole 11, the gas blowing the sounding piece 12 will cause the sounding piece 12 to make a sound to prompt the operator. During the process of the floating ball 13 moving upward under the buoyancy of the oil, the connecting rod 14 will drive the sealing plate 15 to move upward until the collecting pipe 7 is filled with oil. At this time, the sealing plate 15 will enter the sealing groove 10 to prevent the oil generated by releasing the pressure from leaking. At the same time, it provides time for the operator to repair, avoids waste of oil in the lubrication system, and saves resources. In addition, through the setting of the filter screen 2, the debris generated by the fragmentation of the bursting disc 3 is prevented from entering the oil pipeline, ensuring the cleanliness of the oil pipeline of the lubrication system.

[0024] The above - described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
