When the valve cover 3 and the valve body 1 are sealed, the elastic pre-tightening force applied to the valve cover 3 by the elastic connecting structure 5 makes the valve cover 3 pressed against the valve body 1 to ensure that the valve cover 3 and the valve body 1 are sealed, which can improve the sealing performance between the valve cover 3 and the valve body 1 and help ensure the normal operation of the energy storage device.

[0031] For some embodiments, please continue to refer to Figure 1 and Figure 2 The exhaust valve can be applied to the power energy storage cabinet, such as the exhaust valve can be installed on the cabinet door of the power energy storage cabinet. In order to adapt to the size of the cabinet door, the valve body 1 can be generally a rectangular frame structure, the first direction is the length direction of the rectangular frame structure, the second direction is the width direction of the rectangular frame structure, and the third direction in which the valve cover 3 and the valve body 1 are arranged is the thickness direction of the rectangular frame structure.

The arrangement direction of the valve cover 3 and the valve body 1 is the third direction, which can be understood as the thickness or height direction of the rectangular frame of the valve body 1.

[0033] The rectangular frame of the valve body 1 has a long side frame extending in the first direction, and also has a wide side frame extending in the second direction. The body of the driver 4 is mounted on the valve body 1 or is used to be mounted on the energy storage device. In the embodiment in which the body of the driver 4 is mounted on the valve body 1, the bodies of the two drivers 4 can be mounted on the wide side frame of the valve body 1 to meet the requirement that the two drivers 4 are arranged at both ends of the valve body 1 in the first direction; of course, in other embodiments, the bodies of the two drivers 4 can also be mounted on the long side frame of the valve body 1, and the two drivers 4 are respectively close to the wide side frames at both ends, which can also meet the requirement that the two drivers 4 are arranged at both ends of the valve body 1 in the first direction.

[0034] For some examples, please refer to Figure 2 and Figure 3 One or more elastic connection structures 5 can be provided according to the size of the valve body 1 and the valve hole 15 in the first direction. The elastic connection structure 5 is located between the two driving members 4 in the first direction, and multiple elastic connection structures 5 are arranged at intervals.

[0035] The elastic connection structure 5 connects the valve body 1 and the valve cover 3. In one embodiment, please refer to Figure 1 and Figure 2 , the valve body 1 may be provided with a plurality of valve holes 15, and the plurality of valve holes 15 may be arranged in the first direction, the valve body 1 includes an outer frame 11 and a connecting portion 14 connected to the outer frame 11, the outer frame 11 includes a long side frame and a wide side frame connected, the connecting portion 14 extends in the second direction, the connecting portion 14 is located in the outer frame 11, the connecting portion 14 is connected between the two long side frames to divide two adjacent valve holes 15, and the elastic connecting structure 5 may also be connected to the connecting portion 14 of the valve body 1 to meet the requirement that the elastic connecting structure 5 is located between the two driving members 4 in the first direction, so as to avoid the valve cover 3 located between the two driving members 4 in the first direction from being poorly sealed due to deformation. In another embodiment, only one valve hole 15 may be provided, and the valve body 1 does not include the connecting portion 14, so that the elastic connecting structure 5 may be connected to the long side frame of the valve body 1.

[0036] In some embodiments, the elastic connection structure 5 includes a first connecting member 52 and an elastic member 51. The first connecting member 52 extends in a third direction. The first connecting member 52 passes through the valve body 1. One end of the first connecting member 52 is connected to the valve cover 3, and the other end is provided with a limiting portion 53. The elastic member 51 elastically abuts between the valve body 1 and the limiting portion 53.

[0037] As an example, please refer to Figure 1 and Figure 2The first connecting member 52 and the limiting portion 53 may be an integral structure, such as a connecting bolt 8, wherein the screw portion of the connecting bolt 8 forms the first connecting member 52, the bolt head forms the limiting portion 53, the end of the screw portion passes through the valve body 1 and is threadedly connected to the valve cover 3; the elastic member 51 may be a compression spring or a rubber member, the elastic member 51 is sleeved on the first connecting member 52, the elastic member 51 is located between the valve body 1 and the limiting portion 53 in the third direction, one end of the elastic member 51 elastically abuts against the valve body 1, and the other end elastically abuts against the limiting portion 53 On the upper part, the elastic member 51 can apply an elastic pre-tightening force to the limiting portion 53, that is, to the entire first connecting member 52 to make it move away from the valve body 1. Driven by the first connecting member 52, the valve cover 3 has a tendency to move toward the valve body 1 in the third direction. In this way, when the valve cover 3 and the valve body 1 are in a sealed state, under the action of the elastic member 51, the valve cover 3 is pressed against the valve body 1, which can increase the sealing performance of the valve cover 3 and the valve body 1 between the two driving members 4 in the first direction, and can effectively avoid the exhaust valve from being poorly sealed due to the deformation of the valve cover 3.

[0038] In another embodiment, the elastic connection structure 5 may only include an elastic member 51, which may be a tension spring. The elastic member 51 is located between the valve body 1 and the valve cover 3 in the third direction. One end of the elastic member 51 is connected to the valve body 1, and the other end is connected to the valve cover 3. The elastic member 51 can apply an elastic pulling force to the valve cover 3 to move the valve cover 3 toward the valve body 1, thereby ensuring that the valve cover 3 is pressed against the valve body 1 when the valve body 1 and the valve cover 3 are in a sealed state.

[0039] In some embodiments, the number of the driving member 4 can be more than two, as long as there are two driving members 4 arranged at both ends of the valve body 1 in the first direction. The driving end of the driving member 4 is connected to the valve cover 3, please refer to Figure 1 and Figure 2The main body of the driving member 4 may include a driving motor or a driving cylinder, and the driving member 4 also includes a driving rod 41 and a second connecting member 42. The driving rod 41 is transmission-connected to the main body of the driving member 4, and one end of the driving rod 41 away from the main body of the driving member 4 is connected to the second connecting member 42. The second connecting member 42 is connected to the valve cover 3 to form a driving end of the driving member 4; the second connecting member 42 includes a U-shaped sheet structure, and two connecting sheets extending outward are arranged on the bottom wall of the U-shaped sheet structure. The arrangement direction of the two connecting sheets is perpendicular to the arrangement direction of the two parallel side walls in the U-shaped sheet structure, and screw holes are provided on the two connecting sheets for screws to pass through and realize connection with the valve cover 3; or no connecting sheet is provided on the bottom wall of the U-shaped sheet structure, and the screw hole is provided on the bottom wall of the U-shaped sheet structure; the two parallel side walls in the U-shaped sheet structure are rotationally connected to the driving rod 41 through a rotating pin to meet the rotation connection between the second connecting member 42 and the driving rod 41. This can reduce the probability that the drive rod 41 is stuck due to poor guiding performance of the reciprocating movement of the drive rod 41 or a large assembly gap between the drive rod 41 and the body of the driving member 4.

[0040] Of course, if the assembly gap between the driving rod 41 and the main body of the driving member 4 can be ignored, and the driving rod 41 has good guiding performance, the second connecting member 42 may not be provided in the driving member 4, and one end of the driving rod 41 may be directly connected to the valve cover 3.

[0041] For some examples, please refer to Figure 1 and Figure 2 , the body of the driver 4 is mounted on the valve body 1 through an adjustable connection structure to satisfy the adjustable position of the body of the driver 4 relative to the valve body 1 in the third direction, which helps to match the driving force of the driver 4 with the movement stroke of the valve cover 3 relative to the valve body 1, so as to avoid the driver 4 continuously applying force to the valve cover 3 when the valve cover 3 is sealed with the valve body 1. In some other embodiments, the body of the driver 4 is mounted on the energy storage device, and the adjustable connection structure can also be provided between the body of the driver 4 and the energy storage device.

[0042] Specifically, in one embodiment, please refer to Figure 3 The adjustable connecting structure includes a long hole 7 extending in the third direction and a connecting bolt 8 cooperating with the long hole 7. The long hole 7 can be arranged on the body of the driving member 4, or on the valve body 1, or the long hole 7 can be arranged on the body of the driving member 4 and the valve body 1; the connecting bolt 8 passes through the long hole 7 and cooperates with the connecting plate 9 or the nut to fix the driving member 4 on the valve body 1, and the connecting plate 9 is provided with a threaded hole cooperating with the connecting bolt.

[0043] In another embodiment, the adjustable connecting structure includes a connecting bolt and a plurality of gaskets extending in a third direction. Bolt holes for the connecting bolts to pass through are provided on the main body of the driving member 4 and the valve body 1. The position of the main body of the driving member 4 relative to the valve body 1 in the third direction can be changed by increasing or decreasing the number of gaskets.

[0044] In other embodiments, the main body of the driving member 4 can also be directly installed on the valve body 1, and no adjustable connecting structure is set between the main body of the driving member 4 and the valve body 1. During the installation process of the main body of the driving member 4 and the valve body 1, the driving force of the driving member 4 is adjusted to match the reciprocating movement stroke of the valve cover 3.

[0045] In some embodiments, the exhaust valve also includes a mounting portion 6, which is connected to the valve body 1 or to an energy storage device. The mounting portion 6 is located on the side of the valve hole 15 that is away from the valve cover 3 in the third direction, and in the third direction, the orthographic projection of the mounting portion 6 on the valve body 1 is staggered with the valve hole 15, so as to avoid the mounting portion 6 occupying the gas path space discharged from the valve hole 15, thereby ensuring the large displacement requirement of the exhaust valve.

[0046] For details, please refer to Figures 1 to 3 In one embodiment, the mounting portion 6 includes a block-shaped mounting seat, and the mounting portion 6 can be fixed to the valve body 1 by fasteners, and the orthographic projection of the mounting portion 6 on the valve body 1 in the third direction is all located on the outer frame 11; in other embodiments, the mounting portion 6 can also be a frame structure. The driving member 4 is connected to the valve body 1 through the mounting portion 6, and the long hole 7 in the adjustable connection structure can also be provided on the mounting portion 6. In another embodiment, the mounting portion 6 can also be provided integrally with the valve body 1, and the mounting portion 6 is formed on the valve body 1 to achieve connection with the valve body 1.

[0047] Further, in one embodiment, please refer to Figures 1 to 3 The mounting portion 6 also has a mounting surface 61 extending in the third direction, the body of the driver 4 is mounted on the mounting surface 61, the body of the driver 4 is fitted with the mounting surface 61, and the mounting surface 61 can be set to be flush with the hole wall surface of the valve hole 15 in the third direction, which is convenient for the integral molding of the mounting portion 6 and the valve body 1 on the one hand, and helps to simplify the structure of the entire driver 4 on the other hand. Of course, in other embodiments, the mounting surface 61 can also be arranged in a plane perpendicular to the third direction and spaced from the hole wall surface of the valve hole 15.

[0048] Alternatively, in some embodiments, the mounting portion 6 is not provided in the exhaust valve, and the driving member 4 may also be installed on the side of the valve body 1 facing away from the valve cover 3 in the third direction.

[0049] A recessed groove 12 is provided on the side of the valve body 1 facing the valve cover 3 in the third direction. When the valve cover 3 is in a sealed fit with the valve body 1, the valve cover 3 is located in the recessed groove 12, and the side of the valve cover 3 facing away from the valve body 1 in the third direction is flush with the side of the valve body 1, so as to avoid the valve cover 3 protruding from the outer surface of the valve body 1 when the valve cover 3 is in a sealed state with the valve body 1, which helps to ensure the appearance of the entire exhaust valve.

[0050] The valve cover 3 has an outer side surface facing away from the valve hole 15 and an inner side surface facing the valve hole 15 in the third direction. The inner side surface of the valve cover 3 is provided with a plurality of ribs, which can reduce the thickness of the valve cover 3 to achieve the purpose of weight reduction, and can also increase the structural strength of the entire valve cover 3 through the ribs, thereby reducing the probability of deformation of the valve cover 3.

[0051] In some embodiments, the valve cover 3 and the valve body 1 are sealed together through the seal 2. A sealing groove 13 is provided at the bottom of the groove 12. The sealing groove 13 is provided around the valve hole 15. The seal 2 is installed in the sealing groove 13.

[0052] In one embodiment, please refer to Figure 2 and Figure 4 The sealing groove 13 is located between the bottom wall and the groove side wall of the sink groove 12. Among the two groove side walls of the sealing groove 13, one groove side wall is located on the side of the groove side wall of the sink groove 12 away from the valve hole 15, and the other groove side wall is located on the side of the groove side wall of the sink groove 12 facing the valve hole 15. The sealing member 2 fills the entire sealing groove 13, so that the sealing member 2 is embedded in the valve body 1, which can reduce the probability of the sealing member 2 escaping from the sealing groove 13.

[0053] In one embodiment, please continue to refer to Figure 2 and Figure 4 The sealing member 2 includes a first portion 21 extending in a plane perpendicular to the third direction, and also includes a second portion 22 extending in the third direction, and the first portion 21 is connected to the second portion 22, so that the cross section of the sealing member 2 forms an L-shaped structure.

[0054] Furthermore, the second part 22 has a sealing surface 23 that cooperates with the valve cover 3. The sealing surface 23 is arranged toward the valve hole 15, and the sealing surface 23 is arranged inclined relative to a third direction, that is, the sealing surface 23 gradually inclines away from the valve hole 15 in the direction from the valve body 1 to the valve cover 3, so as to provide guidance for the valve cover 3 in the process of moving the valve cover 3 toward the valve body 1, so as to ensure that the valve cover 3 and the valve body 1 are sealed in place, and the sealing area between the valve cover 3 and the seal 2 can be increased by the inclined sealing surface 23, thereby improving the sealing performance between the valve cover 3 and the valve body 1.

[0055] Of course, in other embodiments, the sealing member 2 may also be provided with only the first portion 21 ; or may also be provided with only the second portion 22 , and retain the obliquely arranged sealing surface 23 on the second portion 22 .
