[0016] 2. This is a special control valve group for plate brakes. The principle of the control valve group is that when the pressure signal oil enters from the port and the pressure reaches the pressure set by the hydraulic control reversing valve, the hydraulic control reversing valve opens and flows into the brake through the port, achieving the purpose of opening the brake and making the motor work normally. When the brake is closed, the oil flows out from the port. Since there is no inlet pressure in the hydraulic control reversing valve, the hydraulic control reversing valve quickly resets, so that the oil of the brake begins to return through the port, so that the brake is closed again; when the pressure signal oil enters from the port and the pressure reaches the pressure set by the hydraulic control reversing valve, the hydraulic control reversing valve opens and flows into the brake through the port, achieving the purpose of opening the brake and making the motor work normally. When the brake is closed, the oil flows out from the port. Since there is no inlet pressure in the hydraulically controlled reversing valve, the hydraulically controlled reversing valve quickly resets, causing the brake oil to begin to return through the port, thereby reclosing the brake. This valve group is used to control various motor brakes and has the function of pressure control and regulation. When the brake is closed, it can quickly return oil through the hydraulically controlled reversing valve to ensure safe and stable operation of the motor. All oil ports of this valve group are plate-mounted, reducing pipeline connections and being safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

The shaft 312 passes through the fixed seat 211 and extends. The rotating mechanism 31 also includes a handle 313, which is fixedly mounted on the extended end of the rotating shaft 312. A first bevel gear 314 is fixedly mounted on the outer wall of the rotating shaft 312. A support plate is fixedly mounted on the inner wall of the movable groove 212. One side of the support plate is rotatably connected to a screw rod 4 through a bearing. A screw rod slide plate 213 is threadedly sleeved on the outer wall of the screw rod 4. One end of the screw rod 4 passes through the vertical cavity 311. A second bevel gear 5 is fixedly mounted on the outer wall of the through-end of the screw rod 4. The second bevel gear 5 is meshed with the first bevel gear 314. A groove 6 is provided on the fixed seat 211. A connecting block 7 is slidably connected to the inner wall of the groove 6. The connecting block 7 is fixedly connected to the control valve group body 1. A card slot 8 is provided on one side of the connecting block 7.

[0025] In this embodiment, the device is fixedly installed in a specified position, and the handle 313 is rotated so that the handle 313 drives the rotating shaft 312 to rotate, the first bevel gear 314 rotates, and then drives the second bevel gear 5 that meshes with each other to rotate, so that the screw rod 4 rotates, so that the screw rod slide plate 213 threadedly sleeved on the outer wall of the screw rod 4 slides on the inner wall of the movable groove 212, and the connecting rod 214 pushes the fixed block 215 to move, so that the fixed block 215 is inserted into the inner wall of the groove 8 opened on the connecting block 7, so that the control valve group body 1 can be fixed.

[0026] The following is a detailed description of the working principle of this special control valve group for plate brakes.

[0027] like Figure 1-3As shown, when in use, the device is fixedly installed in a designated position, and the handle 313 is rotated so that the handle 313 drives the rotating shaft 312 to rotate, thereby driving the first bevel gear 314 fixedly sleeved on the outer wall of the rotating shaft 312 to rotate, and then driving the second bevel gear 5 meshing with each other to rotate, so that the screw rod 4 fixedly sleeved on the inner wall of the second bevel gear 5 is driven to rotate, so that the screw rod slide plate 213 threadedly sleeved on the outer wall of the screw rod 4 slides on the inner wall of the moving groove 212, thereby pushing the fixed block 215 through the connecting rod 214.

The principle of the control valve group body 1 is that when the pressure signal oil enters from the A1 port and the pressure reaches the pressure set by the hydraulic control reversing valve, the hydraulic control reversing valve opens and flows into the brake through the B port, so as to achieve the purpose of opening the brake and make the motor work normally. When the brake is closed, the oil flows out from the B port. Since there is no inlet pressure in the hydraulic control reversing valve, the hydraulic control reversing valve quickly resets, so that the oil of the brake starts to return through the T port, so that the brake is closed again; when the pressure signal oil enters from the A2 port and the pressure reaches the pressure set by the hydraulic control reversing valve, the hydraulic control reversing valve opens and flows into the brake through the B port, so as to achieve the purpose of opening the brake and make the motor work normally. When the brake is closed, the oil flows out from port B. Since there is no inlet pressure in the hydraulically controlled reversing valve, the hydraulically controlled reversing valve quickly resets, causing the brake oil to begin to return through port T, thereby closing the brake again.
