[0002] Pressure water tanks are generally used in closed water circulation systems to balance water volume and pressure. Under the condition of meeting the use conditions, pressure water tanks can greatly save water. Therefore, they are widely used in enterprises, institutions, residential areas and rural areas for life, living and office water. They are also used as ballast water tanks for certain specific equipment.

[0051] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0052] The present disclosure provides a water pressure resistance test device, such as Figure 1 As shown, the water pressure resistance testing device includes a first tank body 1, a water injection and drainage unit 2, a gas injection and exhaust unit 3 and a connecting unit 4.

[0053] The first tank body 1 has a first cavity 101 and a second cavity 102 therein.

[0054] The injection and drainage unit 2 is connected to the outer wall of the first tank body 1, and the first part of the injection and drainage unit 2 is connected to the first cavity 101, and the second part of the injection and drainage unit 2 is connected to the second cavity 102. The injection and exhaust unit 3 is connected to the outer wall of the first tank body 1, and the injection and exhaust unit 3 is respectively connected to the first cavity 101 and the second cavity 102. The communication unit 4 is connected to the outer wall of the first tank body 1, and the communication unit 4 is used to connect or disconnect the first cavity 101 and the second cavity 102.

[0055] When the water pressure test device provided by the embodiment of the present disclosure is used to perform a water pressure test on some equipment on a ship, since the water pressure test device includes a first tank body 1, a water injection and drainage unit 2, a gas injection and exhaust unit 3, and a connecting unit 4, and the first tank body 1 has a first cavity 101 and a second cavity 102, different equipment can be placed in the first cavity 101 and the second cavity 102 in the first tank body 1. For example, the first cavity 101 is used to place equipment that is not frequently replaced for ballast testing, and the second cavity 102 is used to place equipment that is replaced more frequently for ballast testing.

[0056] During the test, the connection or disconnection between the first cavity 101 and the second cavity 102 is controlled according to the detection conditions in the first cavity 101 and the second cavity 102. The detection conditions refer to the same pressure.

[0057] If the detection conditions in the first cavity 101 and the second cavity 102 are the same, the first cavity 101 and the second cavity 102 can be always connected through the connecting unit 4 so that the pressures in the first cavity 101 and the second cavity 102 remain the same, that is, the first cavity 101 and the second cavity 102 can be used as one cavity.

[0058] If the detection conditions in the first cavity 101 and the second cavity 102 are different, at this time, the first cavity 101 and the second cavity 102 are disconnected from each other and can be used as two independent cavities. The first cavity 101 and the second cavity 102 can be connected in advance through the connecting unit 4, and then the injection and drainage unit 2 and the injection and exhaust unit 3 are controlled to fill the first cavity 101 and the second cavity 102 with water, and the pressure in the first cavity 101 and the second cavity 102 is gradually increased through the injection and exhaust unit 3. When the pressure value in the second cavity 102 reaches the detection condition of the equipment in the second cavity 102, the connecting unit 4 is controlled to shut off the connection between the first cavity 101 and the second cavity 102. The pressure in the first cavity 101 is adjusted by the injection and exhaust unit 3 until the pressure value in the first cavity 101 reaches the detection condition of the equipment in the first cavity 101.

[0059] That is to say, the first tank body 1 is designed with compartments, which can ensure that the first cavity 101 and the second cavity 102 are connected for ballast testing, and can also ensure that the first cavity 101 and the second cavity 102 are used separately to perform separate ballast tests on different equipment. This can greatly improve the detection efficiency and reduce the detection cost.

[0060] Optionally, the first tank body 1 includes a shell 11 and a partition 12. The partition 12 is located in the shell 11, and the outer peripheral wall of the partition 12 is connected to the inner wall of the shell 11, and the first cavity 101 and the second cavity 102 are located on opposite sides of the partition 12 respectively.

[0061] In the above implementation, the first tank body 1 is configured as a shell 11 and a partition 12, and a closed cavity can be formed by the shell 11. At the same time, the interior of the shell 11 is divided into two by the partition 12 to form a first cavity 101 and a second cavity 102 that are independent of each other.

[0062] In this embodiment, the partition 12 is located at a non-central position of the housing 11 , so that the volumes of the first cavity 101 and the second cavity 102 are different.

[0063] Exemplarily, the volume of the first cavity 101 is larger than that of the second cavity 102. In this way, the first cavity 101 can be used to detect a larger device, and the second cavity 102 can be used to detect a smaller device.

[0064] Optionally, the partition 12 is detachably connected to the shell 11, so that the shell 11 can be used as an independent cavity.

[0065] Figure 2 yes Figure 1 The enlarged view of the first part, combined with Figure 2 The connecting unit 4 includes a pressure equalizing water valve 41 and a pressure equalizing gas valve 42. The pressure equalizing water valve 41 is connected to the bottom wall of the first tank body 1, and the first working port of the pressure equalizing water valve 41 is connected to the first cavity 101, and the second working port of the pressure equalizing water valve 41 is connected to the second cavity 102.

[0067] In the above implementation, the pressure-equalizing water valve 41 can connect the first cavity 101 with the second cavity 102, so that water can flow freely between the first cavity 101 and the second cavity 102, ensuring that the water level between the first cavity 101 and the second cavity 102 is the same. The pressure-equalizing gas valve 42 can connect the first cavity 101 with the second cavity 102, so that gas can flow freely between the first cavity 101 and the second cavity 102, ensuring that the gas pressure between the first cavity 101 and the second cavity 102 is the same.

[0071] In the above implementation, the first steam trap 22 is used to discharge water inside the first cavity 101 , and the second steam trap 23 is used to discharge water inside the second cavity 102 .

[0072] In this embodiment, in order to detect whether the water inside the first cavity 101 is drained clean, the filling and drainage unit 2 also includes a first water dry sensor 26, which is connected to the outer wall of the first tank body 1, and the detection head of the first water dry sensor 26 is located inside the first cavity 101.

[0073] By the same token, in order to detect whether the water inside the second cavity 102 is drained clean, the filling and drainage unit 2 also includes a second water dry sensor 27, which is connected to the outer wall of the first tank body 1, and the detection head of the second water dry sensor 27 is located inside the second cavity 102.

[0074] Similarly, in order to detect whether the first cavity 101 is full of water, the filling and drainage unit 2 also includes a first full water sensor 28, which is connected to the outer wall of the first tank body 1, and the detection head of the first full water sensor 28 is located inside the first cavity 101.

The first inflation valve 31 is connected to the outer wall of the first tank body 1, and the air outlet of the first inflation valve 31 is connected to the first cavity 101, and the air inlet of the first inflation valve 31 is used to communicate with the external inflation interface.

[0077] In the above implementation, the first inflation valve 31 is used to inflate the interior of the first tank body 1 so that the interior of the first tank body 1 has different pressures, thereby performing water pressure resistance tests of different pressures on different equipment of the ship.

[0078] In this embodiment, the first inflation valve 31 is a medium-pressure inflation valve, and the first inflation valve 31 is connected to an external medium-pressure inflation interface, so that the pressure inside the first tank body 1 can be increased quickly.

[0079] Continue to see Figure 2 Optionally, the injection and exhaust unit 3 includes a first exhaust valve 32, which is connected to the outer wall of the first tank body 1, and the air outlet of the first exhaust valve 32 is connected to the second port of the first steam trap 22 and the second port of the second steam trap 23, and the air inlet of the first exhaust valve 32 is connected to the first cavity 101.

[0080] In the above implementation, the first exhaust valve 32 is used to exhaust the gas inside the first tank body 1, so that it is convenient to quickly fill the first tank body 1 with water. The air outlet of the first exhaust valve 32 is connected to the drain pipe of the first steam trap 22, so that when the first tank body 1 is filled with water, the various valves are not fully closed in time or the first full water sensor 28 is damaged, and the water in the first cavity 101 is directly discharged through the first steam trap 22.

[0081] Continue to see Figure 2 Optionally, the injection and exhaust unit 3 also includes a third inflation valve 35, which is connected to the outer wall of the first tank body 1, and the air outlet of the third inflation valve 35 is connected to the first cavity 101, and the air inlet of the third inflation valve 35 is used to communicate with the external inflation interface.

[0082] In the above implementation, the third inflation valve 35 is used to inflate the interior of the first cavity 101 when the first cavity 101 is draining water, so as to quickly drain the water inside the first cavity 101.

[0083] In this embodiment, the third inflation valve 35 is a low-pressure inflation valve, and the third inflation valve 35 is connected to an external low-pressure inflation interface, so that the water inside the first cavity 101 can be discharged as quickly as possible.

[0085] In this embodiment, the fourth inflation valve 36 is a low-pressure inflation valve, and the fourth inflation valve 36 is connected to the low-pressure inflation interface of the outside, so that the water inside the second cavity 102 can be discharged as quickly as possible.

[0086] Figure 3 yes Figure 1 The enlarged view of the second part, combined with Figure 3 The water pressure resistance testing device further includes a second tank body 5 , and a third cavity 501 is provided inside the second tank body 5 .

[0087] The injection and drainage unit 2 also includes a second water injection valve 24 and a third drain valve 25. The second water injection valve 24 is connected to the outer wall of the second tank body 5, and the water outlet of the second water injection valve 24 is connected to the third cavity 501.

[0089] In the above implementation, the second tank 5 is used to test other equipment. At the same time, the second tank 5 is also used to form a cycle with the first tank 1, so that after the test of the first tank 1 is completed, the internal water of the first tank 1 is directly introduced into the second tank 5, so as to perform the test through the second tank 5, thereby saving water.

[0090] When the second tank body 5 and the first tank body 1 are circulated, the third charging valve 35 and the first steam trap 22 in the first tank body 1 are opened, the third steam trap 25 and the second exhaust valve 34 of the second tank body 5 are opened, and the low-pressure gas enters the first tank body 1 through the pipeline and the third charging valve 35, and presses the water in the first tank body 1 into the second tank body 5 through the first steam trap 22 and the third steam trap 25.

[0095] In the above implementation, the second exhaust valve 34 is used to exhaust the gas inside the second tank body 5, so that it is convenient to quickly fill the second tank body 5 with water. The purpose of connecting the gas outlet of the second exhaust valve 34 to the drain pipe is to avoid that after the second tank body 5 is filled with water, each valve component has no time to be completely closed, and the water in the second tank body 5 is directly discharged through the third drain valve 25.

[0096] By the same token, in order to detect whether the water inside the third cavity 501 is drained clean, the filling and drainage unit 2 also includes a third water dry sensor 211, which is connected to the outer wall of the second tank body 5, and the detection head of the third water dry sensor 211 is located inside the third cavity 501.

[0100] In this embodiment, the fifth inflation valve 37 is a low-pressure inflation valve, and the fifth inflation valve 37 is connected to an external low-pressure inflation interface, so that the water inside the third cavity 501 can be discharged as quickly as possible.

[0101] In this embodiment, the water pressure resistance device further includes a plurality of detection water valves 100, wherein the first detection water valve 100 is connected to the outer wall of the first tank body 1, and the two ends of the detection water valve 100 are respectively connected to the first cavity 101 and the first steam trap 22. The second detection water valve 100 is connected to the outer wall of the first tank body 1, and the two ends of the detection water valve 100 are respectively connected to the second cavity 102 and the second steam trap 23.

[0103] In this embodiment, the above valve components are all solenoid valves, and the water pressure resistance device also includes a controller, which is electrically connected to the above valve components and the above sensors.

[0104] Exemplarily, the water pressure resistance test device also includes a drain main valve 61 and a water injection main valve 62. The drain main valve 61 is used to connect the external drain equipment with the first drain valve 22, the second drain valve 23 and the third drain valve 25, and the water injection main valve 62 is used to connect the external water injection equipment with the first water injection valve 21 and the second water injection valve 24 respectively.

[0105] The following briefly introduces the working process of the water pressure resistance test device provided by the embodiment of the present disclosure:

[0106] Since the working mode of the second tank body 5 is similar to that of the first tank body 1 , only the first tank body 1 is taken as an example for description.

[0107] First, the water filling stage of the first tank body 1. The controller controls the first water filling valve 21, the pressure equalizing water valve 41, the pressure equalizing air valve 42 and the first exhaust valve 32 to be powered on and opened, and the low-pressure water source flows into the first water filling valve 21 through the water filling main valve 62, and enters the first cavity 101 and the second cavity 102. At the same time, the air in the first cavity 101 and the second cavity 102 is collected to the external drain interface through the pipeline and the first exhaust valve 32. When the first cavity 101 and the second cavity 102 are full of water, the first full water sensor 28 will feed back the signal to the controller, and the controller controls the first water filling valve 21, the pressure equalizing water valve 41, the pressure equalizing air valve 42 and the first exhaust valve 32 to lose power, and the water filling is completed at this time.

[0108] Then, the first tank body 1 enters the pressurization stage. The controller controls the pressure-equalizing water valve 41, the pressure-equalizing gas valve 42 and the first exhaust valve 32 to be powered on and opened, and the first cavity 101 and the second cavity 102 in the first tank body 1 are pressurized simultaneously, and the medium-pressure gas enters the first cavity 101 and the second cavity 102 through the first inflation valve 31, so that the first cavity 101 and the second cavity 102 are loaded. When the feedback pressure of the first water pressure sensor 210 reaches the required working pressure of the second cavity 102, the first water pressure sensor 210 will feed back the signal to the controller, and the controller controls the first inflation valve 31 to lose power, and the pressurization of the first cavity 101 and the second cavity 102 in the first tank body 1 is completed.

[0109] Next, the controller controls the pressure-equalizing water valve 41 and the pressure-equalizing air valve 42 to be de-energized and closed, and controls the first exhaust valve 32 or the first inflation valve 31 and the first exhaust valve 32 to be energized. When it is necessary to continue to pressurize the first cavity 101, the first inflation valve 31 continues to pressurize the first cavity 101 until the feedback pressure of the first water pressure sensor 210 reaches the required working pressure of the first cavity 101, and then the first inflation valve 31 is closed. When it is necessary to reduce the pressure of the first cavity 101, the first exhaust valve 32 is used to reduce the pressure until the feedback pressure of the first water pressure sensor 210 reaches the required working pressure of the first cavity 101, and then the first exhaust valve 32 is closed.

[0110] Next, the first cavity 101 and the second cavity 102 in the first tank body 1 enter the pressure equalization stage. The controller controls the pressure equalizing water valve 41 and the pressure equalizing gas valve 42 to be powered on and opened, and the first cavity 101 and the second cavity 102 can achieve pressure equalization loading after a short time, and the internal pressures of the first cavity 101 and the second cavity 102 are the same. In other words, if the equipment in the first cavity 101 and the second cavity 102 needs to achieve pressure equalization, the first cavity 101 and the second cavity 102 are pressure equalized, and the pressure equalizing water valve 41 and the pressure equalizing gas valve 42 are always powered on and opened during equipment testing. If the equipment in the first cavity 101 and the second cavity 102 needs to be tested separately in their own independent spaces, the pressure equalizing water valve 41 and the pressure equalizing gas valve 42 are controlled to be powered off and closed, so that the first cavity 101 and the second cavity 102 are independent.

[0111] Next, the first tank 1 pressure relief stage: the controller controls the pressure equalizing valve 42 and the first exhaust valve 32 to be powered on and opened, and the compressed gas in the first cavity 101 and the second cavity 102 is discharged through the pipeline and the first exhaust valve 32 to relieve the pressure. When the first water pressure sensor 210 feedbacks that the pressure in the first cavity 101 has dropped to 0, the first water pressure sensor 210 will feed back a signal to the controller, and the controller controls the pressure equalizing valve 42 and the first exhaust valve 32 to lose power, and the pressure relief of the first tank 1 ends.

[0112] Finally, the first tank 1 is in the draining stage: the first cavity 101 and the second cavity 102 can be drained separately, which can save water. The controller controls the first drain valve 22 and the second drain valve 23 and the third air-charging valve 35 and the fourth air-charging valve 36 to be powered on and opened, and the low-pressure gas enters the first cavity 101 through the pipeline and the third air-charging valve 35, and presses the water in the first cavity 101 into the first drain valve 22 and discharges it into the drain main valve 61. At the same time, the low-pressure gas enters the second cavity 102 through the pipeline and the fourth air-charging valve 36, and presses the water in the second cavity 102 into the second drain valve 23 and discharges it into the drain main valve 61. When the water in the first cavity 101 or the second cavity 102 is drained, the first water-dry sensor 26 or the second water-dry sensor 27 will feed back the signal to the controller, and the controller controls the first drain valve 22 and the second drain valve 23 and the third air-charging valve 35 and the fourth air-charging valve 36 to lose power, and the draining is completed at this time.

[0113] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
