[0002] Motor brakes are widely used in various construction operations. They are mainly controlled by special control valves. The opening and closing of the brakes can be controlled by the opening and closing of the control valves.

[0003] In the past, this was generally achieved by installing a speed regulating valve on the cylinder or motor. However, in this case, it is often difficult to accurately adjust the speeds of both sides to the same speed under different loads and conditions. Therefore, based on the above-mentioned problems, a special control valve group for synchronous diversion is introduced. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-3 As shown, the utility model provides a synchronous diversion dedicated control valve group, including a valve body 1, an oil source port 3 is opened on the valve body 1, a first diversion port 2 is opened on the valve body 1, a second diversion port 4 is opened on the valve body 1, the oil source port 3 is connected to the oil tank, an oil inlet port 6 is opened on the top of one side of the valve body 1, a plurality of mounting holes are opened on the valve body 1, an actuator interface is arranged on the first diversion port 2 and the second diversion port 4, and the first diversion port 2 and the second diversion port 4 are connected to the oil cylinder or the motor, the oil source port 3, the first diversion port 2 and the second diversion port 4 are all connected, and the valve body 1 is made of alloy, and an actuator interface is opened on the first diversion port 2 and the second diversion port 4.

[0021] In this embodiment, hydraulic oil enters from the oil source port 3, passes through the synchronous diverter valve, and is divided into two, and then reaches the actuator through the first diverter port 2 and the second diverter port 4, so that the actuator completes the synchronous work.

[0022] The working principle of this kind of synchronous diversion special control valve group is described in detail below.

[0023] like Figure 1-3 As shown, when in use, the hydraulic oil enters from the oil source port 3, passes through the synchronous diverter valve, and is divided into two, and then reaches the actuator through the first diverter port 2 and the second diverter port 4, so that the actuator completes the synchronous work. The synchronous maintenance diverter / collector valve is a sliding valve core with a pressure compensation effect. It can be used to divert in one direction and collect in the opposite direction. Because of its synchronous maintenance characteristics, this type of valve can keep the two hydraulic cylinders synchronized at the end of the full stroke. When one hydraulic cylinder reaches the end of the stroke, a small pressure-compensated flow will flow into and out of the other hydraulic cylinder and make it reach the end of the stroke. This valve group is a synchronous valve core, so when the actuator runs to the end, this valve can achieve final synchronization and realize the synchronous work of the two cylinders or motors. It is mainly used in occasions where the actuator has high requirements for speed synchronization during operation.
