DETAILED DESCRIPTION

[0014] A self-reciprocating high-frequency valve, comprising a reciprocating rod 1, a breathable guide sleeve 2, a hydraulic cylinder 3, a return spring 1 4, a valve seat 5, a sliding valve core 6, a return spring 2 7, a sliding valve core adjusting screw 8, a relief valve 9, an oil pump 10, a motor 11, an oil tank 12, an oil supply channel 13, an oil return channel 14, and a working chamber 15;

[0015] The reciprocating rod body 1 is arranged in the valve seat 5, the return spring 1 4 is arranged on the reciprocating rod body 1, the air-permeable guide sleeve 2 is connected to the outside of the reciprocating rod body 1, and the hydraulic cylinder 3 is arranged on the valve seat 5;

[0016] The sliding valve core 6 is arranged inside the valve seat 5, the sliding valve core adjusting screw 8 is connected to the sliding valve core 6, and a return spring 7 is arranged outside the sliding valve core adjusting screw 8;

[0017] The relief valve 9 is arranged at the rear of the valve seat 5, the oil pump 10 is arranged at the rear of the relief valve 9 and is connected to the relief valve 9, and the motor 11 is arranged at the rear of the oil pump 10 and is connected to the oil pump 10;

[0018] The oil tank 12 is arranged outside the oil pump 10 and connected to the oil pump 10. The oil tank 12 is provided with an oil supply channel 13 and an oil return channel 14. The working chamber 15 is arranged in the valve seat 5. The oil supply channel 13 and the oil return channel 14 are respectively connected to the working chamber 15.

[0019] The oil supply channel 13 is connected to the oil tank 12, the oil pump 10, the overflow valve 9, the sliding valve core 6 and the working chamber 15 in sequence.

[0020] The oil return passage 14 sequentially connects the oil tank 12 , the sliding valve core 6 and the working chamber 15 .

[0021] The working principle of the present invention is as follows: the motor 11 is powered on and rotated (clockwise) to drive the one-way high-pressure oil pump 10 to work, outputting high-pressure oil, which enters the oil supply channel 13 through the relief valve 9 and then enters the working chamber 15 and one end of the slide valve core 6. At this time, the reciprocating rod body 1 is pushed by the high-pressure oil to overcome the force of the return spring 1 4 and extend to the left. When it reaches the end point, the system pressure further increases. When it is greater than the force of the return spring 2 7 on the slide valve core 6, the slide valve core 6 opens, thereby opening the oil return channel 14, allowing the high-pressure oil to flow out. The oil flows back to the oil tank 12 through the return oil channel 14. At this time, the pressure in the oil supply channel 13 drops rapidly to 0, that is, the pressure in the working chamber 15 is 0. At the same time, under the action of the return spring 14, the reciprocating rod 1 retracts rapidly to the terminal end. At this time, under the action of the return spring 27, the slide valve core 6 closes rapidly again, and the return oil channel 14 is closed. The oil supply channel 13 starts to build up high-pressure oil again and pushes the reciprocating rod 1 to extend. This cycle continues. As long as the motor is powered on and rotates, the reciprocating rod 1 will continue to perform reciprocating linear motion.
