In certain embodiments, the cross-sectional area of the third column section 313 decreases in sequence in the direction from the first column section 311 to the common rail device 400, and the second column section 312 of this shape is less prone to brittle failure due to stress concentrations; in other embodiments, the third column section 313 may also be a straight column section with a constant cross-sectional area, so that the connector 300 has a stepped shaft structure, which is convenient for processing, and the shape of the third column section 313 is not particularly limited herein.
Because the cross-sectional areas of the first column section 311 and the second column section 312 are large, the valves are arranged on the first column section 311 and/or the second column section 312, and the installation space is large; and the connection stability is good when the first column section 311 is used as a connection position with the mounting frame 100. In some embodiments, the cross-sectional area of the first column section 311 is smaller than the cross-sectional area of the second column section 312, the first column section 311 is a stud, connected to a throat hoop, the second column section 312 is a square column or a cylinder, etc., without limitation.

The material of the connector 300 may be non-metal (such as plastic) or metal (such as aluminum alloy and stainless steel, etc.), which is not limited in this application.

Specifically, when an abnormal increase in the flow rate of the medium occurs in the medium passage 411 of the common rail device 400, the relief valve 360 may decrease the opening of the first passage 341 to decrease the flow rate of the medium entering the medium passage 411 from the second passage 342, and gradually return the opening of the first passage 341 to the normal opening when the medium in the medium passage 411 returns to the normal flow rate.
The stop valve 350 is normally opened during the process of supplying and injecting the medium, and of course, the second channel 342 can be opened and closed according to the medium supply requirement, so that the medium can enter the medium channel 411 from the inner cavity of the storage container 200 through the first channel 341 and the second channel 342, or the medium can enter the inner cavity of the storage container 200 from the medium channel 411 through the second channel 342 and the first channel 341; when a certain storage container 200 fails, the stop valve 350 can be used for realizing independent control on the storage container 200, stopping the external air supply of the failed storage container 200, other storage containers 200 can be used normally, and different storage containers 200 are not affected.

When accidents such as combustion occur around the medium storage system, the pressure of the medium in the storage container 200 is increased, possibly causing explosion risk, and the temperature is increased to the set temperature, the safety pressure relief device can automatically open the medium discharged through the tail valve 210, so that the safety performance is improved. When the throat 220 is provided at both ends of the storage container 200 in the axial direction, the tail valve 210 is provided on the throat 220 away from the connector 300.
The discharge path for the medium in the storage container 200 where the tail valve 210 is not provided is: the storage container 200 without the tail valve 210, the corresponding connector 300, the media channel 411 of the track 410, the corresponding connector 300 of the storage container 200 with the tail valve 210, and the tail valve 210 are low cost, but have a somewhat longer response time.

For the storage container 200, the storage container 200 with pressure released may be regarded as downstream of the connector 300 connected to the storage container 200 without the tail valve 210, in which case the overflow valve 360 of the connector 300 connected to the storage container 200 without the tail valve 210 may be activated by mistake, resulting in a significant decrease in the flow rate of the communication channel of the connector 300, affecting the normal supply of medium or pressure release to the outside of the storage container 200 without the tail valve 210. To reduce the probability of the relief valve 360 being activated by mistake, in some embodiments, a tail valve 210 is provided on each storage vessel 200 to ensure that the relief valve 360 is activated only in the event of a media leak downstream, and the presence of a tail valve 210 on each storage vessel 200 also shortens the response time for the venting.
In some embodiments, the tail valve 210 is connected to the throat 220 of the corresponding storage container 200, and is communicated with the storage container 200 through the throat 220, so that the medium in the storage container 200 is discharged through the throat 220 and the tail valve 210 in sequence, and when the set temperature is reached, the temperature drives the safety pressure relief device to open the tail valve 210, so that the safety performance is improved.
