Description
Technical Field
[0001] This application relates to the field of tank pressure testing equipment, and in particular to an automatic circulating water pressurization test bench. Background Technology
[0002] Deep-sea equipment such as submarines require water tanks, which withstand significant external water pressure during actual operation, necessitating high pressure resistance. After production, the water tanks undergo pressure testing to assess their manufacturing quality based on deformation.
[0003] Existing pressurization equipment includes a water injection device and a pressurization device. The water injection device includes a water injection pipe and a water injection pump. One end of the water injection pipe is connected to the water injection pump, and the other end is detachably connected to the water tank to be tested. The water injection pump pumps water from an external water source into the water tank. When the water tank is full of water, the water injection pipe is kept closed through a water valve. The pressurization device includes a pressurization pipe and a pressurization pump. One end of the pressurization pipe is connected to the pressurization pump, and the other end is detachably connected to the water tank to be tested. After the water tank is full of water, the pressurization pump pressurizes and depressurizes the water tank to be tested, thereby achieving the effect of testing the pressure resistance performance of the water tank.
[0004] The aforementioned technical solutions have the following drawbacks: during the testing process, there is a chance that the water tank will break, which may cause leakage of the testing water inside the tank, making the cleaning of the testing site more troublesome and the testing efficiency lower. Utility Model Content
[0005] To improve the efficiency of testing multiple water tanks, this application provides an automatic circulating water injection and pressurization test bench.
[0006] The automatic circulating water injection and pressurization test bench provided in this application adopts the following technical solution:
[0007] An automatic circulating water injection and pressurization test bench includes a holding tank, a lower connector, and an upper connector. The holding tank is used to hold a sealing test tank. The lower connector is connected to the sealing test tank, and the upper connector is also connected to the sealing test tank. The lower connector is used to inject water into the sealing test tank, and the upper connector is used to pressurize and depressurize the sealing test tank.
[0008] By adopting the above technical solution, by setting a lower connector and an upper connector on the holding tank, the sealing test tank can be placed inside the holding tank for testing. The upper connector and the lower connector are connected to the sealing test tank respectively, so that water can be injected and drained inside the sealing test tank. By placing the tank to be tested into the sealing test tank, the tank to be tested is subjected to water pressure, thereby achieving the testing purpose and improving the testing efficiency.
[0009] Optionally, a heat exchange tube is installed inside the container. The heat exchange tube is connected to a chiller, and low-temperature cooling water is continuously circulated through the heat exchange tube to cool the sealed test container.
[0010] By adopting the above technical solution, heat exchange tubes are installed inside the container, enabling heat exchange between the heat exchange tubes and the sealing test tank. When the sealing test tank is filled with water and pressurized, the temperature inside the sealing test tank rises. By circulating low-temperature cooling water through the heat exchange tubes, the low-temperature cooling water can absorb the heat from the sealing test tank, thereby reducing the temperature of the sealing test tank and decreasing the probability of the water temperature inside the sealing test tank rising and evaporating.
[0011] Optionally, the heat exchange tube is configured as a spiral structure and is sleeved outside the sealed testing tank.
[0012] By adopting the above technical solution, and by setting the heat exchange tube to a spiral structure, the length of the heat exchange tube inside the container is increased, thereby increasing the heat exchange area between the heat exchange tube and the sealed testing container and improving the cooling efficiency.
[0013] Optionally, the container can be used to hold cooling water.
[0014] By adopting the above technical solution, cooling water is filled in the container, which soaks the sealed test container, thereby enabling the sealed test container to quickly exchange heat with the heat exchange tube and improve the cooling efficiency.
[0015] Optionally, the bottom of the container is provided with multiple support rods to support the container. The bottom of the container has mounting holes, through which the lower connector passes and is detachably connected to the sealing test container.
[0016] By adopting the above technical solution, by opening an installation hole at the bottom of the container, the lower connector can be inserted into the installation hole and connected to the sealing test tank inside the container. By setting a support rod at the bottom of the container, the support rod supports the container, thereby creating a large space at the bottom of the container, which facilitates the user to install and remove the lower connector.
[0017] Optionally, the lower connector includes a thick water pipe and a water injection pump. One end of the thick water pipe is connected to the water injection pump, and the other end is provided with a connecting flange for connecting to the sealing test tank. A water valve is provided on the thick water pipe for controlling the on / off state of the thick water pipe.
[0018] By adopting the above technical solution, a water pump is connected to one end of the thick water pipe, and the other end can be detachably connected to the sealing test tank. This allows the water pump to inject water into the sealing test tank through the thick water pipe. After the water injection is completed, the water valve is closed. When the upper connector pressurizes the sealing test tank, the probability of water flowing out of the sealing test tank from the thick water pipe is reduced, thereby improving the detection accuracy.
[0019] Optionally, a sealing plate is provided on the thick water pipe, through which the thick water pipe passes and is sealed to the sealing plate. The sealing plate is used for detachable connection to the bottom of the container.
[0020] By adopting the above technical solution, a sealing plate is installed on the thick water pipe, and the thick water pipe is connected to the sealing plate. After the end of the thick water pipe is connected to the sealing test tank, the user installs the sealing plate on the container, thereby sealing the installation hole and keeping the container well sealed.
[0021] Optionally, the upper connector includes a thin water pipe and a pressure pump. One end of the thin water pipe is connected to the pressure pump, and the other end is connected to the sealing test tank. A valve is installed on the thin water pipe to control the opening and closing of the thin water pipe.
[0022] By adopting the above technical solution, a pressure pump is installed on the thin water pipe, which can pressurize the sealed test tank through the thin water pipe, thereby increasing the water pressure in the thin water pipe to achieve the test effect. After the test is completed, the user can drain the water in the sealed test tank through the thick water pipe, improving the drainage efficiency and enabling other sealed test tanks to be installed into the holding tank more quickly.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By setting a lower connector and an upper connector on the holding tank, the sealing test tank can be placed into the holding tank for testing. The upper connector and the lower connector are connected to the sealing test tank respectively, so that water can be injected and drained into the sealing test tank. After water is injected, the sealing test tank can be pressurized to achieve the testing effect and improve the testing efficiency.
[0025] 2. By installing heat exchange tubes inside the container, the heat exchange tubes can exchange heat with the sealing test tank. When the sealing test tank is filled with water and pressurized, the temperature inside the sealing test tank rises. By passing low-temperature cooling water through the heat exchange tubes, the low-temperature cooling water can absorb the heat of the sealing test tank, thereby reducing the temperature of the sealing test tank and reducing the probability of the water temperature inside the sealing test tank rising and evaporating.
[0026] 3. By installing a sealing plate on the thick water pipe, the thick water pipe is connected to the sealing plate. After the end of the thick water pipe is connected to the sealing test tank, the user installs the sealing plate on the container, thereby sealing the installation hole and maintaining the container's better sealing performance.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.
[0034] This application discloses an automatic circulating water injection and pressurization test bench, referring to... Figure 1 , Figure 2 and Figure 5 The system includes a holding tank 1, a lower connector 2, an upper connector 3, and a heat exchange pipe 4. The opening of the holding tank 1 is vertically upward, and the holding tank 1 is used to place the sealing test tank 5. The sealing test tank 5 is placed coaxially in the holding tank 1. The lower connector 2 and the upper connector 3 are detachably connected to the sealing test tank 5. The sealing test tank 5 is used to place the tank to be tested. The two end faces of the sealing test tank 5 are respectively provided with an upper water inlet 51 and a lower water inlet 52. The upper water inlet 51 is connected to the upper connector 3, and the lower water inlet 52 is connected to the lower connector 2. The lower connector 2 is used to introduce test water into the sealing test tank 5, and the upper connector 3 is used to pressurize the sealing test tank 5, thereby pressurizing the tank to be tested inside the sealing test tank 5 to complete the test. Heat exchange tube 4 is installed inside the holding tank 1. During the pressurization process of the water contained in the sealing test tank 5, the temperature inside the sealing test tank 5 rises. Heat exchange tube 4 is used to cool the sealing test tank 5, thereby reducing water evaporation and making the test results more accurate. A pressure sensor is installed on the sealing test tank 5. The pressure sensor can be installed on the upper connector 3 and is installed on the sealing test tank 5 along with the upper connector 3. The pressure sensor is used to detect the pressure inside the sealing test tank 5. During pressurization and depressurization, the pressure sensor continuously monitors the pressure inside the sealing test tank 5, and the user can end the test based on the detection results of the pressure sensor.
[0035] Reference Figure 3 and Figure 4The bottom of the container 1 is provided with multiple support rods 11, which are used to support the container 1 on the ground, so that the bottom of the container 1 is suspended in the air. The bottom of the container 1 is provided with mounting holes 12, and the lower connector 2 passes through the mounting holes 12 and is connected to the lower connector 2.
[0036] Reference Figure 3 and Figure 4 The lower connector 2 includes a thick water pipe 21 and a sealing plate 22. One end of the thick water pipe 21 is fitted with a connecting flange 211, and the other end is connected to a water pump. The connecting flange 211 is detachably connected to the sealing test tank 5, allowing the thick water pipe 21 to be sealed to the lower inlet 52. A water valve 23 is installed on the thick water pipe 21 to control its flow. A through hole is formed in the center of the sealing plate 22, through which the thick water pipe 21 passes and is sealed to the sealing plate 22. Multiple connecting holes 221 are formed on the sealing plate 22, into which bolts can be installed. The sealing plate 22 is detachably connected to the bottom of the holding tank 1, sealing the mounting hole 12. The holding tank 1 contains cooling water. When the sealing test tank 5 is placed inside the holding tank 1, the cooling water soaks the sealing test tank 5, thereby improving the efficiency of heat exchange between the heat exchange pipe 4 and the sealing test tank 5.
[0037] Reference Figure 1 and Figure 2 The upper connector 3 includes a thin water pipe 31 and a valve 32. One end of the thin water pipe 31 is equipped with a flange, and the other end is connected to a booster pump. The valve 32 is installed on the thin water pipe 31 and is used to control the opening and closing of the thin water pipe 31. When the empty sealing test tank 5 is placed inside the holding tank 1, the test water is injected into the sealing test tank 5 through the thick water pipe 21. The thick water pipe 21 has a large flow rate, which can quickly fill the sealing test tank 5 with test water. After the sealing test tank 5 is filled with test water, the water valve 23 is closed.
[0038] Reference Figure 1 The heat exchange tube 4 is configured as a spiral tube, and the length direction of the spiral structure of the heat exchange tube 4 is parallel to the length direction of the holding tank 1. The heat exchange tube 4 is installed inside the holding tank 1. When the sealing detection tank 5 is installed inside the holding tank 1, the sealing detection tank 5 is installed inside the heat exchange tube 4.
[0039] The implementation principle of this application embodiment is as follows: by placing the sealing test tank 5 inside the holding tank 1, the two ends of the sealing test tank 5 can be connected to the lower connecting member 2 and the upper connecting member 3 respectively, so that the water injection pump can inject water into the sealing test tank 5. The water injection flow rate is large and the water pressure is low, so that the test tank inside the sealing test tank 5 is subjected to water pressure and the test is completed. During the test, the water temperature inside the sealing test tank 5 rises. The heat exchange pipe 4 is connected to the air-cooled scroll chiller. Low temperature cooling water can be continuously introduced into the heat exchange pipe 4, thereby cooling the sealing test tank 5 and the water inside the sealing test tank 5.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
