Description

Technical Field

[0001] This utility model relates to the field of pipeline valve technology, and in particular to a vacuum pipeline logistics check valve. Background Technology

[0002] Vacuum pipeline logistics collection systems are a rapid means of material transport in modern buildings. They utilize negative pressure technology to pump items (such as household waste and hospital linens) through a pre-laid pipeline system to a central collection station for centralized processing. These systems are commonly used in hospitals, commercial complexes, high-end residences, airports, train stations, and many other living environments. In vacuum pipeline logistics systems, check valves are a key component, used to prevent backflow of materials within the pipelines.

[0003] However, existing vacuum pipeline logistics collection systems generally do not have check valves to prevent exhaust gas backflow, which makes it easy for exhaust gas to backflow into the vacuum pipeline.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a vacuum pipeline material flow check valve, which aims to improve the problem that the existing vacuum pipeline material flow collection system generally does not have a check valve to prevent the backflow of exhaust gas, thus causing the exhaust gas to easily flow back into the vacuum pipeline.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum pipeline logistics check valve, comprising a rectangular tube, wherein a rectangular flange is fixedly connected to the outer wall of the rectangular tube, and a flow-stopping component is provided on the left side of the inner wall of the rectangular flange;

[0007] The flow-stopping assembly includes multiple valve plates, all of which are disposed on the left side of the inner wall of the rectangular flange. Multiple evenly distributed reinforcing plates are fixedly connected to the right side of the multiple valve plates. A rotating shaft is connected through the middle of the reinforcing plates. A shaft frame is provided on the inner wall of the rectangular flange. Multiple evenly distributed shaft seats are slidably connected to the inner wall of the shaft frame. A fixing assembly is provided on the outer wall of the rectangular tube.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes a plurality of evenly distributed first bolt holes, all of which are opened on the outer side wall of the rectangular tube. The outer side wall of the shaft frame is provided with a plurality of evenly distributed second bolt holes, and fastening bolts are threaded into the interior of the plurality of first bolt holes.

[0010] As a further description of the above technical solution:

[0011] Both ends of the plurality of rotating shafts are rotatably connected to the inner sidewall of the bearing seat.

[0012] As a further description of the above technical solution:

[0013] The middle rear ends of the plurality of fastening bolts all penetrate the first bolt hole and are threaded to the inner sidewall of the second bolt hole.

[0014] As a further description of the above technical solution:

[0015] Both ends of the inner sidewall of the shaft frame are fixedly connected to baffles, and the two baffles include angle iron.

[0016] As a further description of the above technical solution:

[0017] Multiple evenly distributed support plates are fixedly connected to the middle of both angle irons.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, multiple evenly distributed rotating shafts are installed inside the rectangular tube, and multiple evenly spaced reinforcing plates are rotatably connected to each rotating shaft. At the same time, a valve plate is fixedly connected to the left end of the reinforcing plate. When the airflow in the pipe blows open the valve plate, the gas can flow out of the pipe through the valve, but the airflow outside the valve cannot blow open the valve plate and enter the pipe. This effectively prevents the backflow of exhaust gas in the pipe.

[0020] 2. In this utility model, by pre-reserving multiple evenly distributed first bolt holes on the rectangular tube for connection with the shaft frame, and correspondingly opening multiple evenly distributed second bolt holes on the shaft frame, the shaft frame and the rectangular tube can be connected to each other by tightening bolts, which can effectively reduce production costs, facilitate installation, and facilitate later maintenance.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 , Figure 6 , Figure 8 and Figure 9 One embodiment of this utility model is a vacuum pipeline logistics check valve, which includes a rectangular tube 1, a rectangular flange 101 fixedly connected to the outer wall of the rectangular tube 1, and a flow-stopping component provided on the left side of the inner wall of the rectangular flange 101.

[0035] The flow-stopping assembly includes multiple valve plates 2, all of which are located on the left side of the inner wall of the rectangular flange 101. Multiple evenly distributed reinforcing plates 202 are fixedly connected to the right side of the multiple valve plates 2. A rotating shaft 201 is connected through the middle of the reinforcing plate 202. A shaft frame 3 is provided on the inner wall of the rectangular flange 101. Multiple evenly distributed shaft seats 301 are slidably connected to the inner wall of the shaft frame 3. A fixing assembly is provided on the outer wall of the rectangular tube 1. The front and rear ends of the multiple rotating shafts 201 are rotatably connected to the inner wall of the shaft seats 301.

[0036] Specifically: By adding a reinforcing plate 202 to the valve plate 2, the strength of the valve plate 202 can be effectively increased. At the same time, the valve plate 2 is connected to the shaft frame 3 through the rotating shaft 202, so that the valve plate 202 moves smoothly and is not easy to jam.

[0037] Reference Figure 2 , Figure 5 , Figure 7 and Figure 8 The fixing component includes multiple evenly distributed first bolt holes 5, which are all opened on the outer side wall of the rectangular tube 1. Multiple evenly distributed second bolt holes 501 are opened on the outer side wall of the shaft frame 3. Fastening bolts 6 are threaded into the interior of the multiple first bolt holes 5. The rear end of the middle part of the multiple fastening bolts 6 passes through the first bolt holes 5 and is threaded into the inner side wall of the second bolt holes 501.

[0038] Specifically: By opening multiple evenly distributed first bolt holes 5 on the rectangular tube 1 and correspondingly opening multiple evenly distributed second bolt holes 501 on the shaft frame 3, the shaft frame 3 and the rectangular tube 1 can be connected to each other by tightening bolts 6.

[0039] Reference Figure 2 , Figure 4 and Figure 10 Both ends of the inner sidewall of the shaft frame 3 are fixedly connected to baffles 4, and the two baffles 4 include angle irons 401; multiple evenly distributed support pieces 402 are fixedly connected to the middle of the two angle irons 401.

[0040] Specifically: the baffle 4 is composed of angle iron 401 and support plate 402. The baffle 4 can prevent the valve plate 2 from moving in the opposite direction, thereby preventing gas backflow.

[0041] Working principle: The device has multiple evenly distributed rotating shafts 201 installed inside the rectangular tube 1, and multiple evenly spaced reinforcing plates 202 are rotatably connected to each rotating shaft 201. At the same time, a valve plate 2 is fixedly connected to the left end of the reinforcing plate 202. When the airflow in the pipeline blows open the valve plate 2, the check valve opens, and the gas can flow out of the pipeline through the valve. However, the airflow outside the valve cannot blow open the valve plate 2 and enter the pipeline. When the pipeline exhaust gas is exhausted, the check valve closes, isolating the outside from the pipeline, thus effectively preventing the situation of exhaust gas backflow in the pipeline.

[0042] Meanwhile, by pre-reserving multiple evenly distributed first bolt holes 5 on the rectangular tube 1 to connect with the shaft frame 3, and correspondingly opening multiple evenly distributed second bolt holes 501 on the shaft frame 3, the shaft frame 3 and the rectangular tube 1 can be connected to each other by tightening bolts 6, which can effectively reduce production costs, facilitate installation, and facilitate later maintenance. Furthermore, the installed baffle 4 is composed of angle iron 401 and support plate 402. The baffle 4 can prevent the valve plate 2 from moving in the opposite direction, thereby preventing gas backflow.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
