Description

Technical Field

[0001] This utility model relates to the field of helium leak detection technology, specifically an auxiliary plug for helium leak detection in liquid-cooled pipelines. Background Technology

[0002] Leaks in liquid-cooled piping (typically non-conductive but corrosive specialized liquids) can directly contact high-voltage server components, potentially causing serious accidents such as short circuits and fires, damaging expensive hardware. For equipment like liquid-cooled piping, which demands extremely high stability and reliability, helium leak detection can effectively prevent significant losses due to leaks.

[0003] However, some joints in existing liquid cooling pipelines lack threads, making it impossible to seal them with threaded plugs. Furthermore, helium leak detection requires a pressure greater than 1 MPa, and conventional plugs such as silicone plugs are difficult to secure. Silicone plugs are also prone to detaching under high pressure, preventing helium leak detection from being performed correctly. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary plug for helium leak detection in liquid cooling pipelines to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A helium leak detection auxiliary plug for liquid cooling pipeline includes a sealing mechanism. The sealing mechanism includes a first cylinder and a second cylinder. A cylindrical silicone gasket for sealing is provided between the first cylinder and the second cylinder. A connection mechanism for connecting the sealing mechanism to the liquid cooling pipeline is provided on the first cylinder and the second cylinder.

[0006] Preferably, the connecting mechanism includes two through holes symmetrically opened around the center of the second cylinder, and a valve stem is inserted into the inside of the through holes. A spring for valve stem reset is provided on the valve stem.

[0007] Preferably, one end of the second cylinder is connected by a plurality of fixing bolts to a fixing cover plate for sealing the valve stem.

[0008] Preferably, the first cylinder and the second cylinder are provided with bolt bodies inside for use with the valve stem to fix the first cylinder and the second cylinder to the joint and the liquid cooling pipeline. The end of the bolt body near the valve stem is hemispherical, and the other end of the bolt body abuts against the end of the first cylinder through multiple sealing gaskets.

[0009] Preferably, the circumferential surface of the bolt body is composed of a threaded portion and a smooth portion, the threaded portion of the bolt body is connected to the internal thread of the second cylinder, and the smooth portion of the bolt body is in contact with the inner wall of the first cylinder.

[0010] The beneficial effects of this utility model are: In this invention, by setting a bolt body, a first cylinder, a second cylinder, a valve stem, and a spring, the problem of difficulty in sealing due to excessive gas pressure during helium leak detection can be effectively solved. At the same time, by changing the first cylinder, the second cylinder, the cylindrical silicone pad, and the spring, it can be applied to helium detection sealing of joints of different sizes, thus improving the practicality of the fixture.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0014] A helium leak detection auxiliary plug for liquid cooling pipelines, such as Figures 1-4 As shown, it includes a sealing mechanism, which includes a first cylinder 3 and a second cylinder 4. A cylindrical silicone pad 5 for sealing is provided between the first cylinder 3 and the second cylinder 4. A connection mechanism for connecting the sealing mechanism to the liquid cooling pipeline is provided on the first cylinder 3 and the second cylinder 4.

[0015] The connecting mechanism includes two through holes 10 symmetrically opened around the center of the second cylinder 4. A valve stem 8 is inserted and connected inside the through holes 10, and a spring 9 for resetting the valve stem 8 is provided on the valve stem 8.

[0016] One end of the second cylinder 4 is connected by a fixing cover plate 6 for sealing the valve stem 8 via multiple fixing bolts 7.

[0017] The first cylinder 3 and the second cylinder 4 are provided with bolt bodies 11 inside, which are used to cooperate with the valve stem 8 to fix the first cylinder 3 and the second cylinder 4 to the connector 2 and the liquid cooling pipeline. The end of the bolt body 11 near the valve stem 8 is hemispherical, and the other end of the bolt body 11 abuts against the end of the first cylinder 3 through multiple sealing gaskets. The gaskets are specifically one or more of stainless steel gaskets and rubber gaskets.

[0018] The circumferential surface of the bolt body 11 is composed of a threaded portion and a smooth portion. The threaded portion of the bolt body 11 is connected to the internal thread of the second cylinder 4, and the smooth portion of the bolt body 11 is in contact with the inner wall of the first cylinder 3.

[0019] In use, first place the valve stem 8 and spring 9 into the through hole 10 at the end of the second cylinder 4. Then, use the fixing bolt 7 to lock the second cylinder 4 and the fixing cover plate 6 to seal the valve stem 8 and spring 9. At this time, put multiple sealing gaskets on the end of the bolt body 11. Then, screw the assembled bolt body 11 through the first cylinder 3 and the cylindrical silicone gasket 5 into the second cylinder 4. When the end of the bolt body 11 touches the valve stem 8, put the first cylinder 3, the cylindrical silicone gasket 5 and the second cylinder 4 into the liquid cooling pipeline. Continue to tighten the bolt body 11 inside the joint, push the valve stem 8 out through the through hole 10, and lock it inside the liquid cooling pipe joint (as the valve stem 8 is pushed out, due to the continuous rotation of the bolt body 11, the end of the bolt body 11 drives the first cylinder 3 to cooperate with the second cylinder 4 to continuously squeeze the cylindrical silicone pad 5. The cylindrical silicone pad 5 is squeezed and expanded, sealing the connection between the first cylinder 3 and the second cylinder 4 and the inner wall of the joint between the first cylinder 3 and the second cylinder 4 and the liquid cooling pipe). Helium leak detection can then be performed on the workpiece.

[0020] Through the above operations, mechanical interlocking is achieved through the valve core, effectively solving the problem of excessive gas pressure and difficulty in fixing the plug during helium leak detection. Furthermore, the use of silicone cylindrical gaskets, sealing rings, silicone gaskets, and stainless steel gaskets achieves axial and parallel sealing of the joint. The auxiliary plug structure is simple, inexpensive, and easy to operate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
