Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a pressure relief cover core for automotive parts. Background Technology

[0002] The pressure relief cover core in automotive parts is a safety device that protects critical components in a turbocharger system. Its core function is to prevent system damage due to overpressure by precisely controlling pipeline pressure. Most pressure relief cover cores used in existing technologies are mechanical. Mechanical pressure relief valves adjust the spring compression by adjusting the screw cap. The screw cap forms a physical barrier with the valve body through its internal threads, but this physical barrier is relatively simple and the sealing effect is insufficient. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pressure relief cover core for automotive parts, which has the advantages of end face sealing and radial sealing, resulting in good sealing performance. This solves the problem that existing technologies, which rely on internal threads to form a relatively simple physical barrier with the outside of the valve body, have insufficient sealing performance.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A pressure relief cover core for automotive parts includes a main body mechanism as the main body of the device. The main body mechanism includes an adjusting cover with a threaded groove on its inner wall. A connecting mechanism is provided inside the main body mechanism. The connecting mechanism includes a connecting shell with an external thread that is threaded to the threaded groove. An inner shell is slidably sleeved inside the connecting shell. A first spring is fixedly connected to the bottom wall of the inner shell. An adjusting shell is fixedly connected to the top of the first spring. A limit ring is fixedly connected to the outside of the inner shell. A set of O-rings is installed below the limit ring on the outside of the inner shell. A second spring is fixedly connected to the inner wall of the adjusting shell. A cover body is sleeved on the outside of the adjusting shell, and the cover body has multiple outlet holes.

[0006] Preferably, the adjusting cover is fixedly connected to a connecting pipe that communicates with the inside of the adjusting cover.

[0007] Preferably, the limiting ring is located between the adjusting cover and the connecting shell, and a sealing ring is installed at the bottom of the limiting ring.

[0008] Preferably, the first and second springs are made of high fatigue life alloy spring steel and are designed as conical springs.

[0009] Preferably, one end of the second spring is connected to the bottom of the cover, and when the first spring and the second spring undergo elastic deformation, the adjusting shell moves up and down inside the cover.

[0010] Preferably, the bottom of the inner shell has a through hole.

[0011] By employing the above technical solution, this utility model provides a pressure relief cover core for automotive parts, which has at least the following beneficial effects:

[0012] 1. This utility model improves the sealing effect of the device by setting a connecting mechanism. The end face sealing between the adjusting cover and the inner shell is achieved by the limiting ring and the sealing ring, and the radial sealing between the adjusting cover and the inner shell is achieved by the O-ring. This allows the device to be sealed in multiple directions during use, which greatly improves the sealing effect of the device and prevents internal pressure leakage.

[0013] 2. This utility model enables the device to release pressure inside the pipe by setting a first spring and a second spring. When the internal pressure is too high, the air pressure drives the regulating shell to rise under the action of the through hole, which causes the second spring to compress the first spring and stretch it, so that the gas is discharged from the gap and then discharged through the outlet hole and enters the connecting pipe, thereby completing the internal air pressure regulation of the device and improving the simplicity of the device.

[0021] 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.

[0022] Most pressure relief caps used in the prior art are mechanical. Mechanical pressure relief valves adjust the spring compression by adjusting the screw cap. The screw cap forms a physical barrier with the outside of the valve body through its internal thread. However, this physical barrier is relatively simple and the sealing effect is insufficient. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a pressure relief cap for automotive parts.

[0023] Example 1:

[0024] Combination Figures 1-4 As shown, a pressure relief cover core for automotive parts is proposed. The main body 1 is set as the main body of the device, and a connecting mechanism 2 is set inside the main body 1. The sealing effect inside the device is effectively improved by the connecting mechanism 2.

[0025] To effectively improve the sealing effect of the device, a connecting mechanism 2 is proposed, mainly composed of a connecting shell 201. The connecting shell 201 is provided with an external thread 202 that is threadedly connected to the threaded groove 103. An inner shell 203 is slidably sleeved inside the connecting shell 201. A through hole is opened at the bottom of the inner shell 203. A first spring 204 is fixedly connected to the bottom wall of the inner shell 203. An adjusting shell 207 is fixedly connected to the top of the first spring 204. A limiting ring 206 is fixedly connected to the outside of the inner shell 203. The limiting ring 206 is located between the adjusting cover 101 and the connecting shell 201. A sealing ring is installed at the bottom of the limiting ring 206. A set of O-rings 205 is installed on the outside of the inner shell 203 below the limiting ring 206. A second spring 208 is fixedly connected to the inner wall of the adjusting shell 207. One end of the second spring 208 is connected to the bottom of the cover 209. When the first spring 204 and the... When the second spring 208 undergoes elastic deformation, the adjusting shell 207 moves up and down inside the cover 209. When the internal pressure is too high, under the action of the through hole, the air pressure drives the adjusting shell 207 to rise, causing the second spring 208 to compress the first spring 204 and stretch it, allowing the gas to be discharged through the gap and then through the outlet hole 210. The gas then enters the connecting pipe 102 through the outlet hole 210, thereby completing the internal air pressure regulation of the device and improving the simplicity of the device. The adjusting shell 207 is fitted with the cover 209, which has multiple outlet holes 210. The end face seal between the adjusting cover 101 and the inner shell 203 is achieved by the limiting ring 206 and the sealing ring, and the radial seal between the adjusting cover 101 and the inner shell 203 is achieved by the O-ring 205. This allows the device to be sealed in multiple directions during use, greatly improving the sealing effect of the device and preventing internal pressure leakage.

[0026] To form the main body of the device, a main body mechanism 1 is proposed, which is mainly composed of an adjusting cover 101. The inner wall of the adjusting cover 101 is provided with a threaded groove 103. A connecting pipe 102 that communicates with the inside of the adjusting cover 101 is fixedly connected to the adjusting cover 101. It is connected to the external thread 202 of the connecting shell 201 through the threaded groove 103. The position of the limiting ring 206 can be fixed by rotating the adjusting cover 101, and the device can be easily disassembled and assembled.

[0027] The first spring 204 and the second spring 208 are made of high fatigue life alloy spring steel, which further improves fatigue strength. They are designed as conical springs, replacing the traditional cylindrical springs. Through gradual stiffness, they adapt to pressure fluctuations and further compress preload deviation.

[0028] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
