[0002] The maintenance of the ultra-high pressure of the six-sided top press depends on the support of the hydraulic system. Figure 1 The figure shows the hydraulically controlled two-position two-way valve used in the six-sided top press. It can be seen from the figure that the hydraulically controlled two-position two-way valve is a normally closed pressure-maintaining valve. When the system is depressurized, the valve opens under the action of the hydraulic control force. With the promotion of diamond technology, the working time of the valve is getting longer and longer, from one minute in ordinary abrasive technology to 180 minutes now. During this period, the hydraulically controlled pump needs to work all the time to maintain a stable hydraulic control force. Taking the 850 type press as an example, the motor configured by the hydraulically controlled pump is 11 kilowatts. Such a depressurization process requires more than 30 degrees of electricity, which greatly wastes energy and urgently needs to be improved. Utility Model Content

The servo motor is used to replace the hydraulic control pump to control the valve. The power consumption is reduced from more than 30 degrees to the current 0.1 degree, which greatly reduces the power consumption of the hydraulic system. After the valve is opened, the valve core moves to the right under the action of pressure to make the servo motor The servo motor has a tendency to reverse, and the positioning rod is inserted into the first positioning hole by the elastic force of the spring, which can prevent the valve core from moving. When the valve needs to be closed, it is only necessary to connect the current to the electromagnetic coil, and the electromagnetic coil generates a magnetic force to attract the iron core to the middle and pull the positioning rod out of the first positioning hole. After the servo motor drives the valve core to move to the left to close the valve, the electromagnetic coil disconnects the current, and the positioning rod is inserted into the second positioning hole under the action of the spring elastic force to fix the valve core again; there is a gap between the valve core and the valve body due to the relative movement, and the hydraulic oil has an overflow problem. A filler block is set between the first positioning hole and the high-pressure oil channel to seal the gap, thereby avoiding the occurrence of hydraulic oil overflow from the positioning rod.
