Description

Technical Field

[0001] The invention belongs to the technical field of pressure-relief fluid, and in particular relates to a pressure-relief fluid connector. Background Art

[0002] A fluid connector is a device used to connect pipelines that transport high-pressure production fluids so that the two components carrying the corresponding connecting ends of the pipeline can move relative to each other. It is widely used in the field of liquid cooling systems or liquid transmission system equipment. However, the current domestic pressure-reducing fluid connectors are not only costly but also have the technical problem of difficulty in plugging and unplugging under high residual pressure. Therefore, there is an urgent need for a pressure-reducing fluid connector to solve the above-mentioned problems. Summary of the invention

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

[0004] In order to achieve the above technical objectives, the specific technical solutions adopted by the present invention are:

[0005] A pressure-relief fluid connector comprises a matching connector plug and a connector socket, wherein a plug pressure-relief valve and a socket pressure-relief valve are respectively arranged inside the connector plug and the connector socket, wherein the plug pressure-relief valve is fixed by a plug front shell and a plug rear shell arranged inside the connector plug, and the socket pressure-relief valve is fixed by a socket front shell and a socket rear shell arranged 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, and the socket pressure relief valve includes a first valve core, a second sealing gasket, a second valve core, a socket fixed valve and a fixed valve core. During the connection process of the connector plug and the connector socket, the sliding plug moves horizontally under the drive of the end face of the rear shell of the plug. During the movement, the sliding plug is separated 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 state of squeezing the spring, and the sliding plug drives the first valve core inside the connector socket to move horizontally, so that the second sealing gasket inside the connector socket is separated from the first valve core, so that the liquid enters the socket through the fixed valve core to prevent the formation of huge high pressure and damage. As the sliding plug is further pushed forward, the second valve core is pushed, and then the second valve core is separated from the socket fixed valve, thereby forming a larger fluid passage, thereby realizing the flow of fluid in the connector, the connector plug and the 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 realizing the sealing again and blocking the fluid passage.

[0007] Furthermore, a connecting nut is provided inside the connector plug to facilitate docking, separation and locking with the connector socket through the connecting nut.

[0008] Furthermore, the plug front housing and the plug rear housing are threadedly connected via the threaded portion at the connection point, and the socket front housing and the socket rear housing are also threadedly connected via the threaded portion at the connection point.

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

[0010] 1. The present invention mentions a pressure-relief fluid connector, which ensures the circulation 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 a plug front shell and a plug rear shell arranged inside the connector plug, and the socket pressure-relief valve is fixed by a socket front shell and a socket rear shell arranged inside the connector socket, so that it has sufficient sealing protection to ensure that impurities or air will not penetrate into the liquid cooling system through the pressure-relief fluid connector.

[0011] 2. The present invention mentions a pressure-relieving fluid connector, which drives the connector plug and the connector socket to be threadedly connected through a connecting nut, which is convenient for docking, separation and locking through threads. The front shell of the plug and the rear shell of the plug are connected by threads, so that the plug pressure-relieving valve can be fixed inside the connector plug. The front shell and the rear shell of the socket are connected by threads, so that the socket pressure-relieving valve can be fixed inside the connector socket. It has a simple structure, is easy to operate, and can also ensure sealing and normal passage of fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In one embodiment of the present invention, Figures 1 to 5 As shown, a pressure relief fluid connector comprises a matching connector plug 1 and a connector socket 2, wherein a plug pressure relief valve 3 and a socket pressure relief valve 4 are respectively arranged inside the connector plug 1 and the connector socket 2, wherein the plug pressure relief valve 3 is fixed by a plug front housing 5 and a plug rear housing 6 arranged inside the connector plug 1, and the socket pressure relief valve 4 is fixed by a socket front housing 7 and a socket rear housing 8 arranged inside the connector socket 2. The plug pressure relief valve 3 comprises a sliding plug 9, a push rod 10, a spring 11 and a first sealing gasket 12, and the socket pressure relief valve 4 comprises a first valve core 13, a second sealing gasket 14, a second valve core 15, a socket fixed valve 17 and a fixed valve core 16.

[0025] A connecting nut is also provided inside the connector plug 1, which is convenient for docking, separation and locking with the connector socket 2 through the connecting nut. The front shell 5 of the plug and the rear shell 6 of the plug are threadedly connected through the threaded part at their connection, and the front shell 7 of the socket and the rear shell 8 of the socket are also threadedly connected through the threaded part at their connection.

[0026] In the process of connecting the connector plug 1 and the connector socket 2 of the present invention, the sliding plug 9 moves horizontally under the drive of the end surface of the plug rear shell 6. 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 state of squeezing the spring 11. The sliding plug 9 drives the first valve core 13 inside the connector socket 2 to move horizontally, so that the second sealing gasket 14 inside the connector socket 2 is separated from the first valve core 13, so that the liquid enters the socket through the fixed valve core 16, thereby preventing the formation of a fluid passage. The second valve core 15 is pushed and then separated from the socket fixed valve 17 to form a larger fluid passage, thereby realizing the flow of fluid in the connector. The connector plug 1 and the 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 action of the spring 11, thereby realizing sealing again and blocking the fluid passage. In short, the present invention has the advantages of simple structure, high production cost, good sealing, ensuring normal passage of fluid and convenient plugging and unplugging under high residual pressure.
