DETAILED DESCRIPTION

[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] When implementing: Figure 1-5As shown, a pressure storage tank comprises: a cylinder 1, one side of the cylinder 1 is connected with a joint 2; a storage mechanism 3, the storage mechanism 3 is installed on the inner side of the cylinder 1, and the surface of the storage mechanism 3 extends to the outside of the cylinder 1; wherein the storage mechanism 3 comprises a pressure relief component 31 arranged inside the cylinder 1, the surface of the pressure relief component 31 extends to the outside of the cylinder 1, and a supporting component 32 is arranged at the lower end of the pressure relief component 31, and the surface of the supporting component 32 is arranged on the surface of the cylinder 1;

[0025] like Figure 1-Figure 5 As shown, the pressure relief assembly 31 includes a fixed plate 311 fixedly connected to the inner wall of the cylinder 1 and a pressure relief chamber 312 sleeved on the surface of the cylinder 1, the upper end of the fixed plate 311 is fixedly connected to an internal buffer chamber 313, the inner top wall of the internal buffer chamber 313 is fixedly connected to a top block 314, a guide channel 315 is provided inside the top block 314, a backflow prevention device 316 is installed on the inner wall of the guide channel 315, a buffer tube 318 is fixedly connected to the inner wall of the internal buffer chamber 313, a liquid flow port 319 is provided on the surface of the buffer tube 318, an air intake pipe 317 is fixedly connected to the inner wall of the internal buffer chamber 313, the other end of the air intake pipe 317 penetrates into the interior of the buffer tube 318, and the other end of the air intake pipe 317 is communicated with the outside of the internal buffer chamber 313;

[0026] When the material set inside the cavity formed by the combination of the cylinder 1 and the fixed plate 311 is stored, the internal pressure of the cylinder 1 increases. At this time, the gas is introduced into the buffer tube 318 through the air inlet pipe 317. Since the surface of the buffer tube 318 is provided with a liquid flow port 319 and the liquid flow ports 319 are all arranged between adjacent air inlet pipes 317, the impact of the fluid injected into the cavity can be alleviated, and the injection can be gentle. When the gas enters the internal buffer bin 313, the fluid in the internal buffer bin 313 will be below the internal buffer bin 313, and at the same time, the gas will accumulate above the internal buffer bin 313. The accumulated gas is introduced into the pressure relief bin 312 through the guide channel 315 inside the top block 314, thereby improving the storage safety.

[0027] The backflow prevention device 316 includes a first positioning ring 3161 and a second positioning ring 3162 fixedly connected to the inner wall of the guide channel 315, the inner wall of the second positioning ring 3162 is slidably connected to a sliding rod 3163, and one end of the sliding rod 3163 close to the first positioning ring 3161 is fixedly connected to a blocking cone 3165, and the surface of the blocking cone 3165 contacts the inner wall of the first positioning ring 3161, and the other end of the sliding rod 3163 is fixedly connected to a positioning ball 3164, and the positioning ball 3164 contacts the inner wall of the second positioning ring 3162, and the surface of the second positioning ring 3162 is provided with an air flow channel 3167, and the surface of the sliding rod 3163 is sleeved with a spring 3166, and the two ends of the spring 3166 are respectively in contact with the surfaces of the blocking cone 3165 and the air flow channel 3167. When the internal pressure of the internal buffer bin 313 increases, the gas enters the pressure relief bin 312 through the flow guide 315, so that the gas pushes the blocking cone 3165. At this time, the blocking cone 3165 drives the positioning ball 3164 to move synchronously through the sliding rod 3163. When the pressure on both sides is balanced, the blocking cone 3165 can be pushed to the inner concave part of the first positioning ring 3161 by the action of the spring 3166 to reset and block. When the material is stored in the cylinder 1, the internal pressure can be prevented from increasing, thereby improving the safety of storage.

[0028] like Figure 1 and Figure 2 As shown, the supporting assembly 32 includes two mounting seats 321 mounted on the lower end of the cylinder 1, a bottom plate 322 is fixedly connected between the two mounting seats 321, a plurality of reinforcing ribs 323 are fixedly connected to the upper end of the bottom plate 322, and the upper end arc surface of the reinforcing ribs 323 contacts the lower end of the cylinder 1. By cooperating with the bottom plate 322 and the reinforcing ribs 323, the supporting force on the lower part of the cylinder 1 is improved, so that the effect of more stable and safe storage is achieved when the lower part of the cylinder 1 is subjected to internal pressure.

[0029] When the utility model is in use, a cavity is formed by combining the cylinder 1 and the fixed plate 311 to store materials. When the internal pressure of the cylinder 1 increases, the gas is introduced into the buffer tube 318 through the air inlet pipe 317. The surface of the buffer tube 318 is provided with a liquid flow port 319 to alleviate the impact of the fluid injected into the cavity. When the gas enters the internal buffer bin 313, the fluid in the internal buffer bin 313 will be at the lower part of the internal buffer bin 313. The gas accumulated above the internal buffer bin 313 is introduced into the pressure relief bin 312 through the guide channel 315 in the top block 314. The gas enters the pressure relief bin 312 through the guide channel 315 to push the blocking cone 3165. The blocking cone 3165 drives the positioning ball 3164 to move synchronously through the sliding rod 3163. The pressure on both sides is balanced and the blocking cone 3165 is pushed to reset and block through the spring 3166. When materials are stored inside the cylinder 1, the storage safety is improved.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
