Description

Technical Field

[0001] This utility model relates to the field of gas storage tank testing technology, specifically to a high-pressure gas storage tank pressure testing device. Background Technology

[0002] Storage equipment, also known as storage tanks, has pressure that is directly affected by temperature, and the medium is often flammable, explosive, or toxic. The main structural forms of storage tanks are horizontal storage tanks, vertical storage tanks, and spherical storage tanks. Gas storage tanks refer to tank-shaped storage equipment for storing gases.

[0003] In existing technologies, after the production of high-pressure gas storage tanks is completed, a pressure testing and holding test is required to check whether the gas storage tank meets the standards for use. During the test, a booster pump is often used to introduce gas into the tank and observe the pressure change and the pressure holding effect. However, when introducing gas, the booster pump pipeline and the gas inlet of the tank are connected by a flange and multiple sets of bolts. In actual use, this method has the following drawbacks: users need to tighten the bolts at the corresponding points in sequence, resulting in low connection efficiency. Moreover, during the test, the flange connection is prone to loosening due to the influence of gas pressure, affecting the connection stability and test results.

[0004] Based on this, this utility model designs a high-pressure gas storage tank pressure testing device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pressure testing device for high-pressure gas storage tanks.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pressure testing device for a high-pressure gas storage tank includes a booster pump and a tank body. The output end of the booster pump is equipped with a conduit that connects to the air inlet of the tank body. One end of the conduit and the air inlet of the tank body are both provided with flanges for connection. The device also includes a locking mechanism located on the outside of the flanges and used to quickly connect the two flanges. The locking mechanism comprises two semi-circular boxes and a set of abutment posts. The abutment posts are located inside the semi-circular boxes, which are fitted onto the outside of the flanges. One end of each abutment post extends into a flange hole within one of the flanges and can move vertically.

[0008] Furthermore, the inner top wall of the semi-circular box is provided with a set of mating plates, one end of which extends sequentially into the flange holes in the two flanges, and the interior of the mating plates is provided with grooves for mating with the ends of the abutting columns.

[0009] Furthermore, a drive rod is installed at the other end of the abutment post, a sleeve is sleeved on the outside of the drive rod, and a piston plate that is slidably connected to the inside of the sleeve is installed at one end of the drive rod.

[0010] Furthermore, the interior of the semi-circular box is provided with an arc-shaped tube, which is connected to the sleeve.

[0011] Furthermore, the conduit is provided with two branch pipes, one end of which is inserted into a semi-circular box and connected to an arc-shaped pipe. Solenoid valves are provided on the outside of both the conduit and the branch pipes to stop the gas supply and complete the gas sealing, thereby achieving the locking treatment at the docking point.

[0012] Furthermore, a spring is fitted on the outer side of the drive rod, and the spring is installed between the piston plate and the contact post;

[0013] Furthermore, two magnets are embedded on one side of the semicircular box, and the opposite sides of two adjacent magnets are magnetically connected to assist the docking of the two semicircular boxes.

[0014] Furthermore, the tank is equipped with a pressure sensor, a safety valve interface, and an exhaust port.

[0015] Beneficial effects

[0016] 1. By setting up semi-circular boxes and docking plates, users can fit the two semi-circular boxes onto the outside of the flange, insert the docking plate into the corresponding flange hole to complete the pre-installation, and use multi-point abutment columns to connect with the grooves in the corresponding docking plates in sequence to complete the quick docking and improve docking efficiency.

[0017] 2. By setting up a branch pipe, the gas in the conduit is introduced into the sleeve. The air pressure drives the contact column to connect with the docking plate, thereby completing the lateral limit of the two flanges. The outer edge of the contact column and the docking plate are used to press the outside of the two flanges, thus ensuring the stability of the connection and the test effect.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A pressure testing device for a high-pressure gas storage tank includes a booster pump 100 and a tank 200. The output end of the booster pump 100 is equipped with a conduit 300 that connects to the air inlet of the tank 200. One end of the conduit 300 and the air inlet of the tank 200 are both provided with flanges for connection. The device also includes a locking mechanism 400, which is located on the outside of the flanges and is used to quickly connect the two flanges. The locking mechanism 400 includes two semi-circular boxes 410 and a set of abutment posts 420. The abutment posts 420 are located inside the semi-circular boxes 410, which are fitted onto the outside of the flanges. One end of the abutment posts 420 extends into a flange hole in one of the flanges and can move vertically.

[0028] In this embodiment of the invention, before the pressure test, the locking mechanism 400 is used to quickly connect the air inlet to the flange at the end of the conduit 300. Then, the booster pump 100 is started to introduce external gas into the tank 200 along the conduit 300. After the preset pressure value is reached, the gas supply is stopped, and the tank 200 is observed for any leakage. At the same time, the pressure holding condition inside the tank 200 is observed, and the pressure holding standard is compared to complete the entire test.

[0029] In this embodiment of the utility model, when docking two flanges, the user can attach the two flanges with an external sealing gasket, then put the semi-circular box 410 on the outside of the flange, and then drive the gas to drive the abutment post 420 inside the semi-circular box 410 into the corresponding flange hole to complete the quick docking.

[0030] It should be noted that during the gas transportation process, gas transportation will be stopped when the gas supply is sufficient to complete the docking operation.

[0031] In some embodiments, such as Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, a set of docking plates 411 are provided on the inner top wall of the semi-circular box 410. One end of the docking plate 411 extends sequentially into the flange hole in the two flanges. The interior of the docking plate 411 is provided with a groove for docking with the end of the abutment post 420.

[0032] After the semi-circular box 410 is fitted onto the outside of the flange, the user can press the mating plate 411 to insert it into the corresponding flange hole, thus completing the pre-installation of the semi-circular box 410.

[0033] It should be noted that the driving source of the contact column 420 in this application is the gas in the conduit 300. The contact column 420 is inserted into the groove in the mating plate 411 to complete the lateral limiting of the two flanges. The outer edge of the contact column 420 is used for pressing and limiting. The contact strength of the outer edge of the contact column 420 is related to the pressure of the introduced gas. The user can adjust the introduced gas pressure according to the required test pressure to ensure connection stability.

[0034] Furthermore, the lower flange is connected to the semi-circular box 410 by bolts, which strengthens the installation stability of the semi-circular box 410 and the bearing capacity of the joint.

[0035] The number of bolts, their installation points, and the screw-in angle can be adjusted according to actual needs to achieve the reinforcement effect required for the test.

[0036] In this embodiment of the utility model, a drive rod 421 is installed at the other end of the abutment post 420. A sleeve 422 is sleeved on the outside of the drive rod 421. A piston plate 423 is installed at one end of the drive rod 421 and slidably connected to the inside of the sleeve 422. Gas is introduced into the sleeve 422, and then the piston plate 423 is driven by the gas. Then the drive rod 421 will drive the abutment post 420 to move and complete the docking with the docking plate 411.

[0037] It should be noted that the diameter of the end of the abutment post 420 in the mating direction is smaller than the inner diameter of the flange hole. This reduces the contact between the abutment post 420 and the flange hole and facilitates efficient mating between the abutment post 420 and the mating plate 411.

[0038] In this embodiment of the utility model, an arc-shaped tube 412 is provided inside the semi-circular box 410, and the arc-shaped tube 412 is connected to the sleeve 422; two branch tubes 310 are provided on the conduit 300, one end of the branch tube 310 passes through the semi-circular box 410 and is connected to the arc-shaped tube 412. Solenoid valves are provided on the outside of the conduit 300 and the branch tubes 310. Gas in the conduit 300 on the branch tube 310 is introduced into the arc-shaped tube 412, and then the gas enters the inside of the sleeve 422. After the introduced gas pressure meets the docking stability, the user can close the solenoid valve on the branch tube 310.

[0039] It should be noted that the branch pipe 310 in this application is a flexible hose, specifically a resin flexible hose, which is lightweight and has good pressure resistance.

[0040] The length, wall thickness, and installation position of the branch pipe 310 can be adjusted according to the actual test requirements to ensure that the gas delivery operation can be completed normally.

[0041] In this embodiment of the utility model, a spring 424 is sleeved on the outside of the drive rod 421. The spring 424 is installed between the piston plate 423 and the contact post 420. After the test is completed, the user can open the solenoid valve on the branch pipe 310 and the conduit 300, and then discharge the gas in the tank 200 through the exhaust port. At this time, the piston plate 423 is no longer under pressure. Then the spring 424 will drive the drive rod 421 and the contact post 420 to reset, so that the user can remove the semi-circular box 410 and the docking plate 411 for the next test.

[0042] In this embodiment of the utility model, two magnets 413 are embedded on one side of the semicircular box 410. The opposite sides of two adjacent magnets 413 are magnetically connected. The use of magnets 413 helps to ensure the fit stability of the two semicircular boxes 410, thereby making the docking of the docking plate 411 and the corresponding flange hole more efficient and improving the efficiency of the entire docking operation.

[0043] It should be noted that the magnet 413 is set up as an auxiliary docking method to improve docking efficiency. The specific docking accuracy needs to be determined by the user. In case of slight misalignment, the user can adjust it manually.

[0044] In this embodiment of the utility model, a pressure sensor, a safety valve interface and an exhaust port are respectively provided on the tank 200. The pressure sensor is used to monitor the pressure inside the tank 200 in real time during the pressurization and pressure holding process. Before the test, the user can install a suitable safety valve through the safety valve interface. After the test is completed, the gas inside the tank 200 can be discharged through the exhaust port.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
