Description

Technical Field

[0001] This utility model relates to the field of storage batteries, and more specifically, it relates to a storage battery process valve that is easy to disassemble. Background Technology

[0002] During the battery manufacturing process, after the batteries come off the production line, they generally need to be cleaned. Since battery cleaning requires removing the valve and cleaning the valve port, workers need to use a valve wrench to unscrew the battery valve before cleaning. After cleaning, the process valve is screwed back on.

[0003] This application aims to provide a battery process valve that can be used in conjunction with the above-mentioned processes to achieve simpler operation and make it easier for operators to disassemble and assemble the process valve. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing process valves, which require multiple disassemblies during manufacturing and whose structures are inconvenient to disassemble, thus reducing production efficiency. It provides a battery process valve that is easy to disassemble, which can improve the convenience of disassembly and assembly while maintaining reliability, making it easier for operators to use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A battery process valve that is easy to disassemble is detachably connected to a battery valve cover. It includes a lower valve part and an upper handle part. The handle part is provided with a hand-tightening mechanism and a valve lever turning mechanism. The valve part includes a rotating body and a slotted boss provided on the side wall of the rotating body. The slotted boss extends radially out of the rotating body. A sealing ring is provided on the bottom surface of the handle part. A slotted bevel is provided on the slotted boss. The slotted bevel is a first bevel arranged spirally along the axis of the rotating body. A spiral second bevel is provided on the valve cover. The first bevel and the second bevel fit together. The process valve is configured such that the pressure between the first bevel and the second bevel increases the further it extends into the valve cover.

[0007] The handle is located outside the battery, and the valve extends from the valve cover into the battery. For easy disassembly and assembly, a convenient hand-tightening mechanism is provided on the handle outside the valve lever turning mechanism, allowing the operator to manually disassemble or install the process valve without using the valve lever device.

[0008] The first and second inclined surfaces on the slot boss generate a force to fix the process valve through an interference fit. The pressure of the interference fit is converted into frictional force, preventing the process valve from detaching from the valve cover. In use, by rotating the rotating body, the slot boss and the valve cover are forced into an interference fit. During this process, the process valve extends into the valve cover, the distance between the sealing ring and the valve cover decreases, and the sealing ring is compressed and deformed, thereby better sealing the valve opening of the valve cover and achieving a sealing effect.

[0009] As preferred, the clamping groove boss further comprises a limiting step abutting against the valve cover to limit the rotation of the clamping groove boss. The limiting step limits the stroke of the process valve, avoiding "slip wire" and causing damage to the first inclined surface and / or the second inclined surface.

[0010] As preferred, the number of the clamping groove bosses is N, and the phase angle of the adjacent clamping groove bosses about the axis of the rotary body is 2π / N. The phase angle is arranged to uniformly distribute the plurality of clamping groove bosses on the side wall of the rotary body.

[0011] As preferred, the number of the clamping groove bosses is two.

[0012] As preferred, the pitches of the first inclined surface and the second inclined surface are different. This feature increases the pressure between the first inclined surface and the second inclined surface as the process valve is screwed in, thereby improving the connection strength between the process valve and the valve cover.

[0013] As preferred, the lowest point of the clamping groove inclined surface is higher than the lowest point of the rotary body. During the installation of the process valve, the process valve needs to be inserted first and then screwed. The inserted part is used as a guide to ensure that the process valve is coaxial with the valve cover.

[0014] As preferred, the hand screwing structure comprises a V-shaped holding structure, and two force grooves are arranged on the two end surfaces of the holding structure in the direction of the V shape. The structure is used for hand screwing, which is convenient to operate, and the force grooves can play a role of anti-skid.

[0015] As preferred, the valve wrench screwing structure comprises a plurality of valve wrench holes on the handle. The valve wrench holes are used for valve wrench operation.

[0016] Compared with the prior art, the utility model has the advantages that:

[0017] (1) simultaneously supporting hand screwing and valve wrench operation, which is convenient for the operator to operate;

[0018] (2) the first inclined surface on the clamping groove boss and the second inclined surface of the valve cover are fixed by interference fit, and the sealing is caused by the deformation of the sealing ring caused by the approach of the process valve to the valve cover.

[0030] Embodiments:

[0031] A battery process valve convenient to disassemble, comprising a valve cover 1, a valve part 2 and a handle part 3, wherein the valve part 2 is detachably connected to the valve cover 1, and the handle part 3 is connected to the valve part 2. Figure 1 As shown in the figure, the valve cover 1 is detachably connected, which comprises a lower valve part 2 and an upper handle part 3. The valve part 2 is used to extend into the valve cover 1 for connection, and the handle part 3 transmits torque to the valve part 2 to provide the force for the valve part 2 to rotate relative to the valve cover 1. In some embodiments, the valve part 2 and the handle part 3 are integrated.

[0032] Referring toFigure 2 and Figure 3 As shown, the handle part 3 is provided with a hand-twisting structure and a valve-plate twisting structure. The hand-twisting structure includes a V-shaped gripping structure 4. Among them, two force-applying grooves 5 are provided on the gripping structure 4, and the force-applying grooves 5 are respectively arranged on the end faces at both ends of the gripping structure 4 along the direction of the V shape. This structure is used for hand-twisting, which is convenient for operation. Among them, the force-applying grooves 5 can play an anti-slip role. The valve-plate twisting structure includes a plurality of valve-plate holes 6 on the handle part 3. The valve-plate holes 6 are used for valve-plate operation. The handle part 3 includes a cylinder with a circular cross-section, and a sealing ring 12 is provided on the outer edge of the bottom surface of the handle part 3.

[0033] The valve part 2 includes a rotating body 7 and a clamping groove boss 8 provided on the side wall of the rotating body 7. The clamping groove boss 8 extends radially out of the rotating body 7. A clamping groove inclined surface is provided on the clamping groove boss 8, and the clamping groove inclined surface is a first inclined surface 9 spirally arranged along the axis of the rotating body 7. A spiral second inclined surface 10 is provided on the valve cover 1, and the first inclined surface 9 and the second inclined surface 10 are in contact.

[0034] Combined Figure 3 、 Figure 4 As shown, the process valve is configured such that the deeper it extends into the valve cover 1, the greater the pressure between the first inclined surface 9 and the second inclined surface 10. Specifically, the pitches of the first inclined surface 9 and the second inclined surface 10 are unequal. This feature makes it that as the process valve is screwed in, the pressure between the first inclined surface 9 and the second inclined surface 10 increases, thereby improving the connection strength between the process valve and the valve cover 1. In another embodiment, the pitches of the first inclined surface 9 and the second inclined surface 10 are the same, and the linear relationship between the screwing depth and the pressure between the first inclined surface 9 and the second inclined surface 10 is achieved by increasing the contact area to provide static friction force.

[0035] Referring Figure 3 As shown, the clamping groove boss 8 further includes a limiting step 11, and the limiting step 11 abuts against the valve cover 1 to limit the rotation of the clamping groove boss 8. This limiting step 11 limits the stroke of the process valve to avoid "slipping of the threads" and causing damage to the first inclined surface 9 and / or the second inclined surface 10. The number of clamping groove bosses 8 is N, and the phase angle between two clamping groove bosses 8 with respect to the axis of the rotating body 7 is 2π / N. The setting of the phase angle makes the multiple clamping groove bosses 8 evenly distributed on the side wall of the rotating body 7. Among them, the number of clamping groove bosses 8 is two, and the phase angle between the two clamping groove bosses 8 is 180 degrees. The lowest point of the clamping groove inclined surface is higher than the lowest point of the rotating body 7. During the installation process of the process valve, it needs to be inserted first and then screwed, and the inserted part is used as a guide to ensure the coaxiality of the process valve and the valve cover 1.

[0036] The handle part 3 is outside the storage battery, and the valve part 2 extends from the valve cover 1 into the interior of the storage battery. For the convenience of disassembly and assembly, a hand-twisting structure convenient for operation is provided on the handle part 3 outside the valve-plate twisting structure, so as to facilitate the operator to manually disassemble or install the process valve without using a valve-plate device.

[0037] The first inclined surface 9 and the second inclined surface 10 on the clamping groove boss 8 generate the force of fixing the process valve through interference fit. The pressure of the interference fit turns into friction force to limit the process valve from being separated from the valve cover 1. In use, the clamping groove boss 8 and the valve cover 1 are forced to interference fit by rotating the rotary body 7, in the process, the process valve is extended into the valve cover 1, the distance between the sealing ring 12 and the valve cover 1 is close, the sealing ring 12 is compressed and deformed to better seal the valve port of the valve cover 1, and the sealing effect is achieved.

[0038] The above-mentioned embodiments are only the preferred schemes of the present application, and do not limit the present application in any form, and other variants and modifications are possible without departing from the technical schemes recited in the claims.
