Description

Technical Field

[0001] The utility model relates to the field of check valves, in particular to a liquid cooling pipeline capable of preventing excessive liquid filling. Background Art

[0002] The pressure relief valve is composed of a valve, a connecting pipe and a drain pipe. It is used to add an overflow valve and a guide pipe on the basis of the original liquid cooling pipe. If the coolant overflows, it will flow through the overflow valve and the guide pipe to the outside of the box, reducing safety hazards and the risk of accidents. It is a device that is more common in daily life.

[0003] The prior art includes a utility model with a publication number of CN205207810U, which discloses a pressure relief valve. The patent adopts a valve core, a positioning pin, a positioning shaft, a top cover and a valve cover. The top cover is covered on the top of the valve cover and is threadedly connected to the valve cover. The valve core is located in the valve cover and compresses and seals the pressure relief port inside the valve cover. The valve core is threadedly fixedly connected to the bottom end of the positioning pin. The top end of the positioning pin is inserted into the inner cavity of the positioning shaft from the bottom, and the top end of the positioning pin can slide up and down in the inner cavity of the positioning shaft. The outer wall of the bottom end of the positioning shaft is threadedly fixedly connected to the top cover, and the top end of the positioning shaft extends to the outside above the top cover, thereby solving the problem. In the assembly process of parts in the previous pressure relief valve, the positioning shaft and the top cover are bonded with solid glue to make the top cover and the positioning shaft connected as one, thus forming a tight fit. Since the positioning shaft and the top cover are bonded with solid glue, usually only temporary or short-term fit can be guaranteed. A long time may easily cause the positioning shaft to fall off longitudinally, directly pressing the valve core, resulting in the inability to discharge the gas normally under high pressure, and the automatic discharge function of the gas under high pressure cannot be realized normally, and it may even easily cause damage to the pressure gauge. In addition, solid glue bonding requires the use of a third-party medium, and the cost of realizing the pressure relief function will also increase accordingly.

[0004] The inventors found in their daily work that in the process of using the pressure relief valve, because the existing pressure relief valve and the connecting pipe are screwed together using multiple screws, the screws need to be screwed multiple times during the connection and disassembly process, resulting in a problem of cumbersome installation and disassembly.
