Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 5, an embodiment 1 of the air spilling device of the present invention includes an air spilling valve, where the air spilling valve includes a valve seat 1, the valve seat 1 has a valve port 10 for communicating a cooling pipeline with the outside, and the valve port 10 is provided with a valve core for closing the valve port 10 by sealing engagement with the valve port 10 under the pressure of cooling liquid in the cooling pipeline and separating from the valve port 10 by external force to open the valve port 10.

In this embodiment, in order to facilitate the production and manufacture of the valve seat 1, the valve seat 1 is cylindrical, the valve core is a valve ball 2, and the valve seat 1 is horizontally installed at the water outlet of the motor 7 in the cooling pipeline. The inner cavity of the valve seat 1 is communicated with a cooling pipeline, an exhaust channel 4 is arranged on the valve seat, the inner side opening of the exhaust channel 4 forms a valve port 10 matched with the valve core, and the valve ball 2 can be in sealing fit with the valve port 10 under the pressure of cooling liquid in the cooling pipeline to close the valve port 10 and be separated from the valve port 10 under the action of external force to open the valve port 10. In this embodiment, the exhaust channel 4 may allow the pushing tool to extend into the air relief valve to push the valve core to open the valve port, and the exhaust channel 4 constitutes a tool operation channel.

Further, in order to improve the sealing effect, the valve port 10 is provided with the sealing rubber ring 6, and the contact sealing performance of the valve ball 2 and the sealing rubber ring 6 is better. In other embodiments, the valve seat may be formed with a diameter gradually decreasing from the position of the valve ball to the position of the exhaust passage, so that the valve ball is in contact with and sealed with the peripheral wall of the valve seat.

As shown in fig. 1, the air overflow device is provided with a sealing cover 5 which is in threaded fit with the valve seat outside an exhaust channel 4 of the valve seat 1, the sealing cover 5 can seal the valve seat 1 when the cooling pipeline is vacuumized to ensure the air tightness of the cooling pipeline, and the threaded section of the valve seat is arranged on the outer peripheral wall so that the threaded section does not affect a valve ball in the valve seat. In other embodiments, the sealing cover can be connected with the valve seat through a buckle or a flange, and the threaded section can be arranged on the inner wall of the valve seat under the condition that the sealing performance between the valve seat and the valve ball is not affected.

As shown in fig. 6, the air overflow device may be installed at the water outlet of the motor 7 in the cooling pipeline, or may be connected to the water outlets of other components in the cooling system through a rigid structure, such as the water outlet of the motor controller 8 in the cooling pipeline, or may be connected to the cooling pipeline 9 through a flexible pipeline.

When excessive gas exists in the cooling pipeline, the gas in the pipeline needs to be discharged, at the moment, a worker opens the sealing cover 5 on the outer side of the valve seat, when the gas circulates to the gas overflowing device in the cooling pipeline, the worker operates a tool to push the valve ball to separate the valve ball 2 from the valve port, and the gas enters the valve seat 1 through the gas inlet channel 3 and then flows out from the gas discharge channel through the periphery of the valve ball 2. After the gas is discharged, the cooling liquid flows to the gas overflow device, the valve ball 2 is pushed to the exhaust channel under the pressure of the cooling liquid to be in the matching sealing of the sealing rubber ring, so that the valve port is closed, and finally the sealing cover 5 is covered, so that the dustproof effect on the valve seat 1 can be achieved. The device has the advantages of simple structure, no restriction of factors such as professional equipment in actual use, convenience in operation and obvious improvement of working efficiency.

In the embodiment of the vehicle of the present invention, the vehicle includes a frame, a cooling pipeline is installed on the frame, and an air overflow device is installed on the cooling pipeline, and the air overflow device in this embodiment has the same structure as the air overflow device in embodiment 1 described above, and is not described again.
