Description

Technical Field

[0001] This invention belongs to the field of pressure-reducing fluid technology, and specifically relates to a pressure-reducing fluid connector. Background Technology

[0002] A fluid connector is a device used to connect pipes that transport high-pressure production fluids, so that two components supporting the corresponding connection ends of the pipe can move relative to each other. It is widely used in liquid cooling systems or liquid transfer systems. However, the pressure-reducing fluid connectors currently available in China are not only expensive, but also have technical problems such as difficulty in insertion and removal under high residual pressure. Therefore, there is an urgent need for a pressure-reducing fluid connector to solve the above problems. Summary of the Invention

[0003] In view of this, the present invention proposes a pressure-reducing fluid connector, which is applied to the field of pressure-reducing fluid technology, and solves the existing technical problems of high cost and difficulty in insertion and removal under high residual pressure.

[0004] To achieve the above-mentioned technical objectives, the specific technical solution adopted by the present invention is as follows:

[0005] A pressure-relieving fluid connector includes a mating connector plug and a connector socket. The connector plug and connector socket are respectively provided with a plug pressure relief valve and a socket pressure relief valve. The plug pressure relief valve is fixed by a plug front housing and a plug rear housing provided inside the connector plug. The socket pressure relief valve is fixed by a socket front housing and a socket rear housing provided inside the connector socket.

[0006] Furthermore, the plug pressure relief valve includes a sliding plug, a push rod, a spring, and a first sealing gasket, while the socket pressure relief valve includes a first valve core, a second sealing gasket, a second valve core, a socket fixing valve, and a fixed valve core. During the connection process between the connector plug and the connector socket, the sliding plug moves horizontally under the action of the rear housing end face of the plug. During the movement, the sliding plug separates from the first sealing gasket on the push rod, thereby forming a fluid passage inside the connector plug. The sliding plug enters the connector socket under the compression of the spring, and the sliding plug drives the first valve core inside the connector socket to move horizontally, causing the second sealing gasket inside the connector socket to separate from the first valve core. This allows liquid to enter the socket through the fixed valve core, preventing the formation of huge high pressure that could cause damage. As the sliding plug advances further, the second valve core is pushed, and then the second valve core separates from the socket fixing valve, thereby forming a larger fluid passage and enabling fluid to flow inside the connector. The connector plug and connector socket, the plug sliding plug, the push rod, the first valve core, and the second valve core return to their original positions under the action of the spring force, thereby achieving a seal again and blocking the fluid passage.

[0007] Furthermore, the connector plug is equipped with a connecting nut inside, which facilitates docking, disengagement, and locking with the connector socket.

[0008] Furthermore, the front and rear housings of the plug are threaded together at their connection points, and the front and rear housings of the socket are also threaded together at their connection points.

[0009] By adopting the above technical solution, the present invention can also bring the following beneficial effects:

[0010] 1. This invention discloses a pressure-relief fluid connector, which ensures the flow of fluid inside the connector through a plug pressure relief valve and a socket pressure relief valve. At the same time, the plug pressure relief valve is fixed by the plug front housing and plug rear housing set inside the connector plug, and the socket pressure relief valve is fixed by the socket front housing and socket rear housing set inside the connector socket, so that it has sufficient sealing protection to ensure that impurities or air will not seep into the liquid cooling system through the pressure-relief fluid connector.

[0011] 2. The pressure-reducing fluid connector mentioned in this invention uses a connecting nut to drive the connector plug and connector socket to form a threaded connection, which facilitates docking, separation and locking through the threads. The front and rear housings of the plug are connected by threads to fix the pressure-reducing valve inside the connector plug. The front and rear housings of the socket are connected by threads to fix the pressure-reducing valve inside the connector socket. The structure is simple, the operation is convenient, and it can also ensure sealing and normal fluid passage. Attached Figure Description

[0023] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0024] In one embodiment of the present invention, such as Figures 1 to 5 As shown, a pressure-relieving fluid connector includes a connector plug 1 and a connector socket 2 for mating connection. A plug pressure-relieving valve 3 and a socket pressure-relieving valve 4 are respectively disposed inside the connector plug 1 and connector socket 2. The plug pressure-relieving valve 3 is fixed by a plug front housing 5 and a plug rear housing 6 disposed inside the connector plug 1, and the socket pressure-relieving valve 4 is fixed by a socket front housing 7 and a socket rear housing 8 disposed inside the connector socket 2. The plug pressure-relieving valve 3 includes a sliding plug 9, a push rod 10, a spring 11, and a first sealing gasket 12. The socket pressure-relieving valve 4 includes a first valve core 13, a second sealing gasket 14, a second valve core 15, a socket fixing valve 17, and a fixing valve core 16.

[0025] The connector plug 1 is also provided with a connecting nut inside, which facilitates docking, separation and locking with the connector socket 2. The front housing 5 and the rear housing 6 of the plug are connected by threads at their connection points, and the front housing 7 and the rear housing 8 of the socket are also connected by threads at their connection points.

[0026] In the connection process of the connector plug 1 and connector socket 2, the sliding plug 9 moves horizontally under the action of the end face of the rear housing 6 of the plug. During the movement, the sliding plug 9 separates from the first sealing gasket 12 on the push rod 10, thereby forming a fluid passage inside the connector plug 1. The sliding plug 9 enters the connector socket 2 under the compression of the spring 11. The sliding plug 9 drives the first valve core 13 inside the connector socket 2 to move horizontally, causing the second sealing gasket 14 inside the connector socket 2 to disengage from the first valve core 13, thereby allowing liquid to enter the socket through the fixed valve core 16, preventing the formation of fluid. The high pressure causes damage. As the sliding plug 9 advances further, the second valve core 15 is pushed. Then, the second valve core 15 separates from the socket fixing valve 17, thereby forming a larger fluid passage. This allows fluid to flow within the connector. The connector plug 1 and connector socket 2, the plug sliding plug 9, the push rod 10, the first valve core 13 and the second valve core 15 return to their original positions under the force of the spring 11, thereby achieving a seal again and blocking the fluid passage. In summary, this invention has the advantages of simple structure, high production cost, good sealing performance, ensuring normal fluid flow and convenient insertion and removal under high residual pressure.

[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
