Description

[0002] Products such as steel buoys, steel pontoons and boats need to have high water tightness during use to ensure their buoyancy and stability in the water. Good airtightness can ensure that the product has sufficient buoyancy in the water and can effectively prevent water from penetrating, thereby ensuring the stability and safety of the product.

[0003] Therefore, these products need to be tested for water tightness after completion to verify whether they meet the air tightness requirements. The most common test method is to pump air into the hull (cylinder, pontoon) through a pump wind rack and evaluate the sealing performance of the product by detecting the change in internal air pressure.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the single pressure gauge pump wind frame used in the past is only equipped with one pressure gauge, and the internal pressure of the boat body is determined by the reading on the pressure gauge. If only one pressure gauge is used, if the pressure gauge fails, the internal pressure of the boat body cannot be confirmed, which poses a great safety hazard. Summary of the invention

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] Products such as steel buoys, steel pontoons and boats need to have high water tightness during use to ensure their buoyancy and stability in the water. Good airtightness can ensure that the product has sufficient buoyancy in the water and can effectively prevent water from penetrating, thereby ensuring the stability and safety of the product.

[0027] Therefore, these products need to be tested for water tightness after completion to verify whether they meet the air tightness requirements. The most common test method is to pump air into the hull (cylinder, pontoon) through a pump wind rack and evaluate the sealing performance of the product by detecting the change in internal air pressure.

[0028] With respect to the above-mentioned related technologies, the inventor believes that the single pressure gauge pump wind frame used in the past is only equipped with one pressure gauge, and the internal pressure of the boat body is determined by the reading on the pressure gauge. If only one pressure gauge is used, if the pressure gauge fails, the internal pressure of the boat body cannot be confirmed, which poses a great safety hazard.

[0029] In order to solve the problem that it is difficult to promptly discover and confirm the internal pressure change when a problem occurs with one pressure gauge, the present application provides a dual-gauge air pumping device for pumping air.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The embodiment of the present application discloses a double-meter air pumping device for pumping air. Figure 1 , Figure 2 A double-meter air pumping device for air pumping includes an air pumping duct 1, one end of which is relatively connected to a device that needs a tightness test. An air inlet component 2 is fixedly connected to the side wall of the air pumping duct 1, one end of which is relatively connected to an external air inlet device, and the other end of which is relatively connected to the inside of the air pumping duct 1. The external gas is injected into the inside of the device to be tested for tightness through the air pumping duct 1 through the air inlet component 2.

[0032] The air inlet assembly 2 includes an air inlet pipe 21, one end of which is fixedly connected to and relatively communicated with an external air inlet device, and the other end of which is fixedly connected to and relatively communicated with a side wall of the air pumping duct 1. A control valve 22 is fixedly connected to the side wall of the air inlet pipe 21. In a specific embodiment, the control valve 22 can be a ball valve, which is rotated to adjust the on-off of the medium inside the air inlet pipe 21, thereby controlling the external gas to enter the inside of the air pumping duct 1 through the ball valve.

[0033] Reference Figure 2 , Figure 3 A first detection pressure gauge 3 is fixedly connected to one end of the air pumping duct 1 which is away from the equipment to be tested for tightness. The interior of the detection end of the first detection pressure gauge 3 is relatively connected to the interior of the air pumping duct 1, and the pressure inside the air pumping duct 1 is detected by the first detection pressure gauge 3.

[0034] A second detection pressure gauge 4 is also fixedly connected to the side wall of the air pumping duct 1 . The interior of the detection end of the second detection pressure gauge 4 is relatively connected to the interior of the air pumping duct 1 . The pressure inside the air pumping duct 1 is detected by the second detection pressure gauge 4 .

[0035] The pressure inside the pump air duct 1 is detected simultaneously by setting the first detection pressure gauge 3 and the second detection pressure gauge 4. When the values ​​of the two pressure gauges are different, it means that one of the first detection pressure gauge 3 and the second detection pressure gauge 4 is damaged, and the pressure detection inside the pump air duct 1 is inaccurate, and an accurate judgment can be made in time.

[0036] Reference Figure 3 , Figure 4 A pressure relief assembly 5 is provided at a position where the air pumping duct 1 is opposite to the air inlet assembly 2. The pressure relief assembly 5 includes a gas safety valve 51. The gas safety valve 51 includes a valve body 511. The valve body 511 is fixedly connected to the air pumping duct 1, and a valve cavity 512 is opened inside the valve body 511. The valve cavity 512 is relatively connected to the inside of the air pumping duct 1.

[0037] A valve cover 513 is fixedly connected to the side of the valve body 511 facing away from the pump air duct 1, and the valve cover 513 includes a connecting portion 5131 fixedly connected to the valve body 511, and a clamping portion 5132 is fixedly connected to the side of the connecting portion 5131 facing away from the valve body 511, and a gas pressure plate 514 is arranged between the clamping portion 5132 and the side wall of the valve body 511. In a specific embodiment, the gas pressure plate 514 is a fusible plate.

[0038] A gas discharge pipe 52 is fixedly connected to the side wall of the valve cover 513 facing away from the valve body 511, and the gas discharge pipe 52 is arranged opposite to the gas pressure sheet 514. The gas discharge pipe 52 is isolated from the inside of the valve cavity 512 by the gas pressure sheet 514. When the gas pressure inside the valve cavity 512 is greater than the tolerable pressure of the gas pressure sheet 514, the gas pressure inside the valve cavity 512 breaks the gas pressure sheet 514, so that the inside of the valve cavity 512 is relatively connected with the inside of the gas discharge pipe 52, and the gas inside the pump air pipeline 1 can be discharged from the position of the gas discharge pipe 52 through the gas safety valve 51.

[0039] The air pumping operation injects air into the boat body through the air pumping frame. When the readings of the first detection pressure gauge 3 and the second detection pressure gauge 4 reach 0.02Mpa, the ball valve switch is closed. The readings of the first detection pressure gauge 3 and the second detection pressure gauge 4 are consistent and stable for more than 30 minutes, indicating that the air tightness of the boat body is good and meets the requirements.

[0040] If only one pressure gauge is used, if the pressure gauge fails, the internal pressure of the boat cannot be confirmed, which poses a certain safety hazard. When two pressure gauges work at the same time, when the two gauges are normal, their readings should be consistent; if one of the gauges is abnormal, the readings of the two gauges will be inconsistent, and the construction personnel can quickly determine this, stop the operation, and replace the pressure gauge, greatly reducing the safety risk.
