[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3 , the utility model provides an embodiment: a combined pipeline pressure release device, including a valve body 1, valve covers 2 are fixedly connected at both ends of the valve body 1, two first connecting plates 4 are fixedly connected to the outside of the valve cover 2, two sliding grooves 8 are provided inside the two first connecting plates 4, and the limiting rods 7 are slidably connected inside the two sliding grooves 8, and the bottom of the limiting rod 7 is fixedly connected to a first spring 9, one side of the limiting rod 7 is fixedly connected to a connecting rod 10, the top of the connecting rod 10 is fixedly connected to a plug-in column 11, and the bottom of the connecting rod 10 is fixedly connected to a reinforcing plate 16, a pipeline body 6 is arranged on one side of the valve body 1, a protective column 20 is fixedly connected to the outside of the pipeline body 6, and two second connecting plates 5 are fixedly connected to the outside of the protective column 20, and two installation grooves 12 are provided inside the two second connecting plates 5, and a sealing assembly is installed inside the valve cover 2, and the sealing assembly is used to seal the valve body 1.

[0025] Specifically, the connection between the pipeline body 6 and the valve body 1 is realized through the second connecting plate 5 on the protective column 20 and the first connecting plate 4 on the valve cover 2. When the plug-in column 11 is pushed into the mounting groove 12, the first spring 9 will push the limit rod 7 and the connecting rod 10 to reset. The close fit between them prevents the loosening or falling off of the connection part, thereby ensuring the stability of the connection. The support of the reinforcement plate 16 inside the mounting groove 12 improves the stability of the connection. The protective column 20 not only provides additional protection for the pipeline body 6, but is also connected to the first connecting plate 4 through the second connecting plate 5 thereon, further enhancing the connection strength between the pipeline and the valve body 1.

[0026] Reference Figure 1-4 The sealing assembly includes a circular rubber ring 3, the outside of the circular rubber ring 3 is fixedly connected to the inside of the valve cover 2, a plurality of second springs 15 are fixedly connected to the inside of the circular rubber ring 3, one end of the plurality of second springs 15 is fixedly connected to a fastening plate 14, a connecting groove 18 is provided on the inner wall of the protective column 20, and a protective groove 17 is provided on the outside of the pipe body 6.

[0027] Specifically, the circular rubber ring 3 serves as a sealing element, and its fixed connection ensures the sealing of the connection between the valve cover 2 and the pipeline, preventing leakage of liquid or gaseous media. The function of the second spring 15 is to provide continuous elastic force to push the fastening plate 14 into the protective groove 17, so that it fits more firmly at the connection between the pipeline body 6 and the valve body 1, thereby enhancing the sealing effect of the fastening plate 14. When the circular rubber ring 3 is compressed and inserted into the connecting groove 18, it can fit tightly with the groove wall to form an effective sealing barrier.

[0028] Reference Figure 2-3 The other end of the first spring 9 is fixedly connected to the inside of the first connecting plate 4, the outside of the connecting rod 10 is slidably connected to the inside of the slide groove 8, the cross-section of the plug-in column 11 is set to be square, the outside of the plug-in column 11 is plugged into the inside of the installation groove 12, and a horizontal plate 13 is fixedly connected between the two corresponding limit rods 7.

[0029] Specifically, the first spring 9 provides elastic support for the limit rod 7, so that the limit rod 7 drives the connecting rod 10 to slide stably in the slide groove 8. The square design of the plug-in column 11 makes it difficult for the plug-in column 11 to rotate relative to the installation groove 12 once it is inserted into the installation groove 12, thereby improving the stability and reliability of the connection. The cross plate 13 provides stability for the limit rod 7 and enhances the structural strength of the limit rod 7.

[0030] Reference Figure 2-4 One side of the valve cover 2 fits with one side of the protective column 20, the outside of the fastening plate 14 is inserted into the inside of the protective groove 17, the outside of the circular rubber ring 3 is inserted into the inside of the connecting groove 18, one end of the pipeline body 6 is inserted into the inside of the valve body 1, and the top of the valve body 1 is fixedly connected with a safety valve 21 and a pressure gauge 19.

[0031] Specifically, the fit between the valve cover 2 and the protective column 20 not only provides a basis for the sealing operation, but also enhances the overall strength of the pipeline connection. The fastening plate 14 is subjected to the elastic force of the second spring 15, and it can fit more closely in the protective groove 17, further enhancing the sealing effect. The circular rubber ring 3 effectively fills the connecting groove 18, further forming a reliable seal, and also protecting the pipeline system from external pollution. The pressure gauge 19 is used to monitor the pressure changes in the pipeline in real time to ensure that the system is in a safe operating state. The safety valve 21 is used as a pressure release device. When the pressure in the pipeline exceeds the set value, it automatically opens to release excess pressure, thereby preventing pipeline rupture or equipment damage.

[0032] Working principle: When it is necessary to connect the pipeline body 6 and the valve body 1, first move the protective column 20 on the outside of the pipeline body 6 close to the valve body 1. At this time, by pressing the horizontal plate 13 downward, the limiting rod 7 slides in the slide groove 8, and then the first spring 9 compresses the tension, so that the connecting rod 10 drives the plug-in column 11 to move downward, and then after the pipeline body 6 is connected to the valve body 1, the protective column 20 fits with the valve cover 2, and the first connecting plate 4 and the second connecting plate 5 overlap, so that the connecting rod 10 drives the plug-in column 11 to be inserted into the installation groove 12, and then the horizontal plate 13 is pulled upward, so that the first spring 9 releases the tension and pushes the limiting rod 7 to move and reset, so that the installation groove 12 further limits the plug-in column 11, and at the same time, the reinforcing plate 16 is inside the installation groove 12, so that the plug-in column 11 is stably plugged in to ensure the firmness of the connection;

[0033] When the pipeline body 6 is close to the valve body 1, one side of the valve cover 2 fits against one side of the protective column 20 to prepare for a sealed connection. At the same time, the circular rubber ring 3 is inserted into the connecting groove 18 on the inner wall of the protective column 20 to form a reliable seal. Then, under the elastic force of the second spring 15, it is further ensured that the fastening plate 14 is in close contact with the connection between the pipeline body 6 and the valve body 1. A safety valve 21 and a pressure gauge 19 are fixedly connected to the top of the valve body 1 to monitor the pressure and safety in the pipeline. When the pressure in the pipeline exceeds the set value, the safety valve 21 will automatically open to release the pressure to prevent pipeline rupture or equipment damage.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
