Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to an automotive valve plate. Background Technology

[0002] The function of the valve plate is to use the control signal output by the control unit to operate and change control elements such as flow rate, pressure, temperature, and hydraulic pressure.

[0003] Currently, most exhaust valve plates in automotive compressor piston cylinders use springs for rebound. When high-pressure gas exerts a force on the valve plate, the spring deforms, thereby changing the flow area of ​​the valve plate and thus changing the gas flow rate. However, when the force exerted by the high-pressure gas on the valve plate is too great, the spring may deform significantly, exceeding its own elastic limit. Consequently, when the external force is removed, the spring cannot fully return to its original shape, thus affecting the normal use of the valve plate.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide an automotive valve plate in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automotive valve plate, including a valve plate body, wherein the valve plate body is provided with a plurality of through grooves and positioning holes arranged in a circumferential array, a plurality of spring pieces located in the through grooves are formed on the valve plate body, and a limiting block for limiting the spring pieces is provided on the valve plate body.

[0007] The present invention is further configured such that: the limiting block includes a support block fixedly connected to the valve plate body, one end of the support block is fixedly connected to an inclined connecting plate, and the end of the connecting plate away from the support block is fixedly connected to an abutment plate.

[0008] The present invention is further configured such that a spring is fixedly connected to the side of the connecting plate near the abutting plate.

[0009] The present invention is further configured such that the length of the spring is greater than the length of the abutment plate.

[0010] The present invention is further configured such that: the spring sheet includes a connecting part and a circular abutting part, the circular abutting part is used to abut against the spring and the abutting plate, and the diameter of the circular abutting part is greater than the width of the connecting part.

[0011] The present invention is further configured such that both the valve plate body and the limiting block are made of aluminum alloy.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The valve plate is installed and positioned through the positioning hole. When the valve plate starts to work, the high-pressure gas exerts a force on the spring plate, causing it to deform and increasing the flow area of ​​the valve plate. When the force on the spring plate is too large, the spring plate will abut against the spring, and the spring will exert a reverse force on the spring plate, reducing the deformation of the spring plate. When the force continues to increase, the spring will compress, and the spring plate will abut against the abutment plate to prevent further deformation of the spring plate, keeping the deformation of the spring plate within its elastic limit. After the high-pressure gas reduces the force on the spring plate, the spring plate will rebound. At the same time, the spring will exert a pushing force on the spring plate to help it rebound, thus enabling the spring plate to return to its original position and giving the spring plate a longer service life.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 and Figure 2As shown, an automotive valve plate includes a valve plate body 1. The valve plate body 1 has several circumferentially arranged through grooves 2 and positioning holes 3. The valve plate body 1 is installed and positioned through the positioning holes 3. Several spring pieces are formed on the valve plate body 1 within the through grooves 2. When the valve plate starts working, high-pressure gas exerts a force on the spring pieces, causing them to deform and increasing the flow area of ​​the valve plate. A limiting block is provided on the valve plate body 1 to limit the movement of the spring pieces. When the force on the spring pieces is too large, the spring pieces will abut against the limiting block, preventing further deformation and ensuring the deformation of the spring pieces is within their elastic limit. After the force of the high-pressure gas on the spring pieces is removed, the spring pieces can completely return to their original position. Both the valve plate body 1 and the limiting block are made of aluminum alloy. Aluminum alloy has high hardness and low density, and it also has good elastic deformation. Therefore, valve plates made of aluminum alloy have the advantages of high hardness and light weight. The spring pieces have good elastic deformation capability, giving the valve plate body 1 a longer service life.

[0019] like Figure 1 and Figure 2 As shown, the limiting block includes a support block 4 fixedly connected to the valve body 1. One end of the support block 4 is fixedly connected to an inclined connecting plate 5. The end of the connecting plate 5 away from the support block 4 is fixedly connected to an abutment plate 6. A spring 7 is fixedly connected to the side of the connecting plate 5 near the abutment plate 6. The length of the spring 7 is greater than the length of the abutment plate 6. Therefore, when the spring is subjected to a large force, the spring will first abut against the spring 7. The spring 7 will deform and exert an opposite force on the spring, thereby slowing down the deformation of the spring. When the force on the spring is too large, the spring will abut against the abutment part, thereby preventing the spring from deforming further and keeping the deformation of the spring within its elastic limit. After the high-pressure gas reduces the force on the spring, the spring will rebound. At the same time, the spring 7 will exert a pushing force on the spring to help it rebound, thereby enabling the spring to reset and giving the spring a longer service life.

[0020] like Figure 1 and Figure 2 As shown, the spring includes a connecting part 9 and a circular abutting part 8. The deformation of the spring mainly occurs in the connecting part 9. The circular abutting part 8 is used to abut against the spring 7 and the abutting plate 6. The diameter of the circular abutting part 8 is larger than the width of the connecting part 9. By providing a circular abutting part 8 with a larger surface area, it can be ensured that the circular abutting part 8 is in full contact with the abutting plate 6 and the spring 7. The width of the connecting part 9 is smaller than that of the circular abutting part 8, so that the connecting part 9 has better deformation capability.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
