Detailed Description
The structure of the automatic oil passage switching valve of the present invention will be further described with reference to fig. 1.
An automatic oil circuit diverter valve structure, characterized by: comprises a valve body 1, a valve core 3 and a pilot electromagnetic valve 2. The valve body 1 is internally provided with a valve cavity 14 extending up and down, an oil outlet 13 communicated with the valve cavity 14, a first oil inlet 11 and a second oil inlet 12 are arranged on the valve wall of the valve body 1, the first oil inlet 11 and the second oil inlet 12 are respectively positioned at the upper side and the lower side of the oil outlet 13, and the oil outlet 13 is positioned in the middle of the valve body. A first sealing ring 4 is arranged on the inner wall of the valve cavity 14 between the first oil inlet 11 and the oil outlet 13, and a second sealing ring 5 is arranged on the inner wall of the valve cavity 14 between the second oil inlet 12 and the oil outlet 13. The valve core 3 is slidably fitted in the valve cavity 14 and has a sealing section 32 on the valve core 3 with a larger diameter than the body of the valve core 3. When the sealing section 32 moves upwards, the sealing section is matched with the first sealing ring 4 to form an upper seal, and is separated from the second sealing ring; when the sealing section 32 moves downwards, it cooperates with the second sealing ring 5 to form a lower seal and is separated from the first sealing ring. The pilot electromagnetic valve 2 is arranged at the lower end of the valve body 1, and a movable valve core of the pilot electromagnetic valve 2 is connected with a valve core 3 of the valve body 1 so as to drive the valve core 3 to move up and down.
Based on the structure, when the oil supply valve works specifically, under a normal condition, the first oil inlet 11 is communicated with the oil outlet 13 through the valve cavity 14 to form an oil supply loop, the valve core 3 is in a lower end free state, and the sealing section 32 on the valve core 3 is matched with the second sealing ring 5 to form a lower seal so as to block the second oil inlet 12 from the oil outlet 13; when the oil supply loop needs to be switched, the pilot electromagnetic valve 2 drives the valve core 3 to move upwards, so that the sealing section 32 is matched with the first sealing ring 4 through the oil outlet 13 to form an upper seal with the first sealing ring 4, the first oil inlet 11 is blocked from the oil outlet 13, and meanwhile, the second oil inlet 12 is communicated with the oil outlet 13 to form the oil supply loop. In the process, the valve core 3 is driven by the pilot electromagnetic valve 2 to move up and down, so that the operation is simple, the precision is high, and the problem of misoperation is solved; on the other hand, the first seal ring 4, the second seal ring 5 and the seal segment 32 are matched to form a stable seal structure, so that the problem of oil leakage does not exist.
Specifically, in order to facilitate automatic return of the spool 3 and stable operation in a natural state, a spring 6 that presses down the spool 3 is provided between the spool 3 and the valve chamber 14. Namely, in a natural state, the first oil inlet 11 is communicated with the oil outlet 13 to realize oil supply, and in the state, the spring 6 is pressed on the valve core 3 to stably keep the valve core 3 in a downward moving state; when the oil supply is switched from the second oil inlet 12 to the first oil inlet 11, the pilot electromagnetic valve 2 is decompressed, and the spring 6 presses the valve core 3 down, so that the valve core 3 moves down.
Further, in order to improve the stability of the assembly of the spring 6 between the valve chamber 14 and the valve body 3, an upper positioning groove 142 for inserting the upper end of the spring 6 is formed on the inner top wall of the valve chamber 14, and a lower positioning groove 31 for inserting the lower end of the spring 6 is formed on the top wall of the valve body 3.
The valve cavity 14 has an annular oil groove 141 on the inner wall corresponding to the oil outlet 13, the first oil inlet 11 and the second oil inlet 12. This structure can avoid case 3 body to shelter from on oil inlet and oil-out 13 to avoid interfering the oil input of oil inlet and the oil output of oil-out 13, can also guarantee the stability of oil pressure business turn over simultaneously.
The diameter of the sealing section 32 is larger than that of the valve core 3, and the end face of the sealing section 32 is provided with an inclination 33. The structure enables the valve core to smoothly enter the sealing ring, and simultaneously increases the oil flow drift diameter and reduces the throttling effect of the oil way.
