Description

Technical Field

[0001] The utility model relates to the technical field of engine solenoid valves, in particular to an engine solenoid valve. Background Art

[0002] During the operation of the engine, the solenoid valve is a key control component, and its working stability and reliability are of vital importance. However, since the solenoid valve will generate a certain amount of heat when working, if it works for a long time without effective heat dissipation measures, it may cause the solenoid valve to overheat, thereby affecting its performance and life. Therefore, designing an effective cooling structure is of great significance to ensure the normal operation of the solenoid valve. The cooling structure includes heat sinks. Heat sinks are set on the outer shell and key parts of the solenoid valve to increase the heat dissipation area and improve the heat dissipation efficiency.

[0003] The cooling structure includes a heat sink. The main function of the heat sink is to improve the heat dissipation effect and prevent the equipment from being damaged by overheating. However, the heat sink is mostly fixed directly on the outer shell of the engine solenoid valve. As the use time increases, the surface of the heat sink will be damaged, and the fixed heat sink cannot be replaced. Failure to replace it in time will affect the cooling quality of the engine solenoid valve, which will increase the cost of maintenance. Therefore, it is particularly important to design an engine solenoid valve. Utility Model Content

[0022] Embodiment 1:

[0023] like Figure 1-3 As shown, an engine solenoid valve comprises two heat sinks 1 and a solenoid valve body 2, the solenoid valve body 2 is arranged at the middle position of the two heat sinks 1, reinforcement plates 3 are arranged on both sides of the solenoid valve body 2, L-shaped plates 4 are arranged on one side of the two reinforcement plates 3, extension rods 5 are arranged on one side of the two L-shaped plates 4, L-shaped blocks 6 are sleeved on both ends of the two extension rods 5, support plates 7 are arranged on the top ends of the four L-shaped blocks 6, the top ends of the two adjacent support plates 7 are respectively fixedly connected to one side of the two heat sinks 1, external threads 12 are provided at both ends of the two extension rods 5, and a restraining plate 8 is fixedly installed between the inner walls of the two adjacent support plates 7, the L-shaped block 6 can move at one end of the extension rod 5, so the position of the heat sink 1 can be adjusted, and the limiting ring 13 can be rotated in the opposite direction to separate the limiting ring 13 from the external thread 12, so that the L-shaped block 6 can be pulled out from one end of the extension rod 5, so that a new heat sink 1 can be replaced.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, a rotating rod 11 is provided on one side of the four L-shaped blocks 6, and one end of the four rotating rods 11 is respectively connected with the internal threads of the four second recessed holes 10 and multiple first recessed holes 9. The utility model is an engine solenoid valve, which is provided with a first recessed hole 9, a second recessed hole 10, a rotating rod 11 and a restraining plate 8. After the inner surface of the heat sink 1 is wrapped with the outer surface of the solenoid valve body 2, one end of the rotating rod 11 is embedded in the corresponding first recessed hole 9 and the second recessed hole 10, and the three are threadedly connected, so that the extension rod 5 and the L-shaped block 6 can be limited and fixed, thereby ensuring the stability of the support plate 7.

[0026] Working principle: During the operation of the engine, the solenoid valve is a key control component, and its working stability and reliability are of vital importance. However, since the solenoid valve will generate a certain amount of heat when working, if it works for a long time and lacks effective heat dissipation measures, it may cause the solenoid valve to overheat, thereby affecting its performance and life. Therefore, designing an effective cooling structure is of great significance to ensure the normal operation of the solenoid valve. The cooling structure includes a heat sink 1. The heat sink 1 is arranged on the outer shell and key positions of the solenoid valve to increase the heat dissipation area and improve the heat dissipation efficiency. Two reinforcement plates 3 are respectively installed on both sides of the solenoid valve body 2, and the reinforcement plates 3 are installed inside the engine, which ensures the stability of the solenoid valve body 2. The solenoid valve body 2 is more secure inside the engine. The extension rod 5 relies on the L-shaped plate 4 to remain fixed. The two heat sinks 1 are respectively fitted with the outer surface of the solenoid valve body 2. The main function of the heat sink 1 is to improve the heat dissipation effect and avoid overheating and damage to the equipment. The heat sink 1 dissipates heat into the air through surface heat exchange, mainly heat convection, to dissipate heat. The sheet 1 can conduct the absorbed heat to various parts internally, making full use of its large heat capacity and surface area to ensure that the heat can be evenly distributed, thereby achieving the effect of cooling the solenoid valve body 2. The L-shaped block 6 can move at one end of the extension rod 5, so the position of the heat sink 1 can be adjusted. By rotating the limit ring 13 in the opposite direction, the limit ring 13 can be separated from the external thread 12, which is convenient for pulling the L-shaped block 6 out of one end of the extension rod 5, so that a new heat sink 1 can be replaced, thereby improving the usability of the cooling structure. After the inner surface of the heat sink 1 is wrapped with the outer surface of the solenoid valve body 2, one end of the rotating rod 11 is embedded in the corresponding first concave hole 9 and the second concave hole 10, and the three are threadedly connected, so that the extension rod 5 and the L-shaped block 6 can be limited and fixed, ensuring the stability of the support plate 7. The heat sink 1 and the L-shaped block 6 are connected through the support plate 7, and the two sides of the restraining plate 8 are respectively connected to one side of the two support plates 7, that is, the movement of the L-shaped block 6 will drive the heat sink 1 to move under the action of the support plate 7 and the restraining plate 8.
