Description

Technical Field

[0001] This utility model relates to the technical field of leakage detection, and in particular to a device for detecting leakage. Background Technology

[0002] When storing sealed liquids in containers, O-rings are used for sealing. This O-ring sealing method is widely used in various fields and has a good sealing effect. This O-ring sealing method is suitable for sealing most liquid scenarios. However, for some hazardous liquids, absolute sealing is required to prevent leakage. Therefore, in cases where absolute sealing cannot be guaranteed, leakage detection methods need to be introduced to mitigate the risk of leakage in advance.

[0003] Traditional methods for detecting leaks include the following: 1. Visual inspection: This method involves directly observing the surface of the equipment or container for liquid seepage or crystal residue. It is suitable for large storage tanks, but requires regular inspections, relies heavily on manual labor, and cannot detect minor leaks.

[0004] 2. Detection using absorbent materials or pH test strips: This method utilizes the principle that pH test strips change color when exposed to liquids, and is suitable for acidic or alkaline liquids such as electrolytes. However, it is a passive detection method, requiring regular material replacement and a certain amount of liquid to seep out until the pH test strip changes color. The response is slow, and it cannot provide real-time alarms.

[0005] 3. Weighing method: Monitor the weight change of the container or equipment to determine whether there is a leak. It requires manual weighing at regular intervals, is not sensitive to minor leaks, and is easily affected by vibration.

[0006] 4. Dyeing method: Add an easily identifiable dye to the liquid and determine the location of the leak by color; this requires manual inspection and cannot be monitored in real time during operation.

[0007] Clearly, none of the above methods can prevent the risk of leakage in advance, so there is an urgent need for a technical means to solve this problem. Utility Model Content

[0008] The purpose of this invention is to provide a device for detecting leaks, so as to solve the problem that existing technologies cannot prevent the risk of leaks in advance.

[0009] To address the aforementioned technical problems, this utility model provides a device for detecting leaks, comprising a container body, a door panel mounted on the container body in an openable and closable manner, and a detection mechanism disposed on the door panel; the door panel has a vent hole through which it passes, and an O-ring seal is provided on one surface of the door panel, the O-ring seal surrounding the periphery of the vent hole. When the door panel is closed, the O-ring seal is clamped between the door panel and the container body, so that the O-ring seal surrounds and forms a closed pressure-holding cavity, the pressure-holding cavity being connected to the vent hole; the detection mechanism is disposed on the surface of the door panel opposite to the O-ring seal, the detection mechanism comprising an air tube and a pressure gauge; the air tube is connected to the vent hole, and the air tube has a controllable opening and closing structure; the pressure gauge is connected to the air tube.

[0010] In one embodiment, the device further includes sealing latches, a plurality of which are disposed at various points around the periphery of the door panel, the plurality of which are used to enhance the tightness of the door panel closure.

[0011] In one embodiment, the sealing latch includes a fixing block, a sealing block, and a sealing handle; the fixing block is located on the container body near the periphery of the door panel; the sealing block is located on the fixing block, and the sealing block is arranged separately from the container body; the sealing handle is rotatably located at the periphery of the door panel, and the sealing handle includes a locked state when turned into the sealing block and the container body, and an unlocked state when turned out of the sealing block and the container body.

[0012] In one embodiment, the door panel has a door handle on the surface opposite to the O-ring seal.

[0013] In one embodiment, in the direction of air supply from the air pipe to the vent, a pressure regulating valve, a switching valve, a tee connector, and a straight pipe connector are sequentially connected to the air pipe; one end of the tee connector is connected to the pressure gauge; the straight pipe connector is threaded to the door panel and is connected to the vent.

[0014] In one embodiment, the pressure gauge is an electronic pressure gauge.

[0015] The beneficial effects of this utility model are as follows: This invention proposes a device for detecting leaks. By filling the pressure chamber with an appropriate amount of gas and then switching the gas tube to the closed state, the gas pressure can be monitored using a pressure gauge. By monitoring the changes in gas pressure, it can be determined whether the O-ring seal is completely sealed. Compared with other traditional methods of detecting leaks, this method can detect whether the O-ring seal is completely sealed before the liquid is stored, thus avoiding risks in advance and preventing losses caused by leaks. It is applicable to any liquid and can monitor the pressure gauge changes in real time during operation, which is of great significance in sealed storage scenarios. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This invention provides a device for detecting leaks, the implementation of which is as follows: Figure 1 As shown, it includes a container body 10, a door panel 20 installed on the container body 10 in an openable and closable manner, and a detection mechanism 30 provided on the door panel 20.

[0021] Regarding the container body 10, as Figure 1 As shown, its interior is mainly used for solution storage, while a door frame structure is provided on one side wall for the installation of door panel 20.

[0022] To ensure a good seal between the container body 10 and the door panel 20 after the door panel 20 is closed, such as Figure 1 and Figure 2 As shown, the device in this embodiment also includes sealing latches 40. Multiple sealing latches 40 are disposed at various points around the periphery of the door panel 20. The multiple sealing latches 40 are used to enhance the tightness of the door panel 20 when closed.

[0023] Specifically, the sealing latch 40 includes a fixing block 41, a sealing block 42, and a sealing handle 43. The fixing block 41 is located on the container body 10 near the periphery of the door panel 20. The sealing block 42 is located on the fixing block 41, and the sealing block 42 is arranged opposite to the container body 10 to form a space between the sealing block 42 and the container body 10 for the sealing handle 43 to enter. The sealing handle 43 is rotatably located at the periphery of the door panel 20 and includes a locked state where it is turned into the space between the sealing block 42 and the container body 10, and an unlocked state where it is turned out of the space between the sealing block 42 and the container body 10.

[0024] After adopting the above setting method, if the door panel 20 is currently in the closed state, simply rotate the sealing handle 43 so that one end of the sealing handle 43 is turned between the sealing block 42 and the container body 10, and the sealing handle 43 will form a tight abutment with the sealing block 42, thereby locking the current position of the door panel 20 and strengthening the tightness of the closure; when it is necessary to open the door panel 20, simply turn the sealing handle 43 out between the sealing block 42 and the container body 10.

[0025] Regarding the door panel 20, as Figure 3 and Figure 4 As shown, in this embodiment, a vent hole 21 is provided on the door panel 20 to pass through it. An O-ring 22 is provided on one surface of the door panel 20. The O-ring 22 surrounds the vent hole 21. So when the door panel 20 is closed, the O-ring 22 is clamped between the door panel 20 and the container body 10, so that the O-ring 22 surrounds and forms a closed pressure-holding cavity 23, and at this time the pressure-holding cavity 23 is connected to the vent hole 21.

[0026] In order to facilitate the opening and closing of the door panel 20, this embodiment also provides a door handle 24 on the surface of the door panel away from the O-ring seal 22, with the two door handles 24 respectively located on the upper and lower parts of the door panel 20.

[0027] Regarding the aforementioned testing institution 30, such as Figure 1 and Figure 4 As shown, in this embodiment, the detection mechanism 30 is located on the surface of the door panel 20 away from the O-ring seal 22. The detection mechanism 30 includes an air pipe 31 and a pressure gauge 32. The air pipe 31 is connected to the vent 21 and has a controllable opening and closing structure. The pressure gauge 32 is connected to the air pipe 31, and preferably, the pressure gauge 32 is an electronic pressure gauge.

[0028] Specifically, at this time, in the direction of air supply from the air pipe 31 to the vent 21, the air pipe 31 is connected in sequence to a pressure regulating valve 33, a switch valve 34, a three-way connector 35, and a straight pipe connector 36; one end of the three-way connector 35 is connected to the pressure gauge 32; the straight pipe connector 36 is threadedly connected to the door panel 20, and the straight pipe connector 36 is connected to the vent 21.

[0029] When applying the gas, an appropriate amount of gas can be introduced into the pressure-holding chamber 23 through the air tube 31, then the switch valve 34 is closed, and the monitoring data of the pressure gauge 32 is observed. If the pressure value can be maintained stably, it indicates that the sealing performance of the O-ring 22 meets the requirements; otherwise, it indicates that the sealing performance of the O-ring 22 is defective.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
