[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: an automatic priority selection valve assembly, including a valve body 1, a power water pipe 2 is fixedly connected to the left end of the valve body 1, a first connecting pipe 17 and a second connecting pipe 18 are fixedly connected to the left and right sides of the top of the valve body 1 respectively, a first buffer cylinder 3 is fixedly connected to the first water outlet pipe 4 at the left end, and a second buffer cylinder 5 is fixedly connected to the second water outlet pipe 6 at the right end, and a first telescopic rod 7 is fixedly connected to the first control valve 8 at the bottom end, and the first control valve 8 is located on the inner wall of the first buffer cylinder 3, and the first telescopic rod 7 is surrounded by a first spring 9 on the outer wall, and the top of the first spring 9 is fixedly connected to the top of the inner wall of the first buffer cylinder 3, and the bottom of the first spring 9 is fixedly connected to the top of the first control valve 8, and the bottom of the second telescopic rod 10 is fixedly connected to the second control valve 11, and the second control valve 11 is located at the bottom of the second buffer cylinder 5, and the outer wall of the second telescopic rod 10 is surrounded by a second spring 12, and the top of the second spring 12 is fixedly connected to the bottom of the inner wall of the second buffer cylinder 5, and the bottom of the second spring 12 is fixedly connected to the top of the second control valve 11.

[0023] Specifically, the outer walls of the second mounting plates 14 on the left and right sides are provided with through openings, and the first control valve 8 and the second control valve 11 can be respectively tightly attached to the through openings to form a sealed state. Before working, the first control valve 8 is squeezed by the first spring 9 at the through opening in the second mounting plate 14 to form a sealed state, and the second control valve 11 is squeezed away from the through opening by the second spring 12, so that it is in an open state with the second mounting plate 14. The first telescopic rod 7 and the second telescopic rod 10 can stabilize the deformation process of the spring so that the spring will not collapse when deformed. At this time, water with a certain power enters the valve body 1 from the power water pipe 2. Because the first control valve 8 on the left is in The valve body 1 is in a sealed state, while the second control valve 11 on the right is in an open state, so that the liquid flows from the second connecting pipe 18 to the second buffer cylinder 5 and flows out from the second water outlet pipe 6. When the water pressure in the valve body 1 increases to a level greater than the pressure of the second spring 12, the water pushes the second control valve 11 and the second mounting plate 14 to close, and the water flow pushes the first control valve 8 upward. At this time, the water pressure in the valve body 1 is greater than the elastic force of the first spring 9, so that the first control valve 8 moves upward, so that the water enters the first buffer cylinder 3 from the first connecting pipe 17 and flows out from the first water outlet pipe 4, finally realizing the ability to automatically change the direction of the water flow according to the pressure inside the valve body 1.

[0024] Reference Figure 3 A plurality of positioning columns 15 are fixedly connected to the top of the first mounting plate 13, and a second mounting plate 14 is fixedly connected to the bottom ends of the first buffer cylinder 3 and the second buffer cylinder 5. A plurality of positioning holes 16 are opened on the outer wall of the second mounting plate 14, and the positions of the plurality of positioning columns 15 correspond to the plurality of positioning holes 16. The first mounting plate 13 and the second mounting plate 14 are connected by a plurality of bolts.

[0025] Specifically, the valve is in a water pressure state for a long time, which makes some parts easy to be damaged. At this time, you only need to use tools to remove the bolts on the first mounting plate 13 and the second mounting plate 14, and then separate the first mounting plate 13 and the second mounting plate 14 to remove the damaged parts, and then replace them with new parts. When replacing, put the positioning column 15 on the first mounting plate 13 into the positioning hole 16 on the second mounting plate 14, so that the first mounting plate 13 and the second mounting plate 14 are stabilized together, so that there will be no deviation when tightening the bolts, which is convenient for tightening the bolts.

[0026] Working principle: Before use, the first control valve 8 and the second mounting plate 14 are in a sealed state, and the second control valve 11 and the second mounting plate 14 are in an open state. Water enters the valve body 1 from the power water pipe 2. Because the first control valve 8 on the left is in a sealed state, and the second control valve 11 on the right is in an open state, the liquid flows from the second connecting pipe 18 to the second buffer cylinder 5 and flows out from the second water outlet pipe 6. When the water pressure in the valve body 1 increases to a pressure greater than the pressure of the second spring 12, the water pushes the second control valve 11 and the second mounting plate 14 to close, and the water flow pushes upward. Move the first control valve 8. At this time, the water pressure in the valve body 1 is greater than the elastic force of the first spring 9, so that the first control valve 8 moves upward, so that water enters the first buffer cylinder 3 from the first connecting pipe 17 and flows out from the first water outlet pipe 4. The valve is in a water pressure state for a long time, which makes some parts easy to be damaged. At this time, you only need to use tools to remove the bolts on the first mounting plate 13 and the second mounting plate 14, and then replace them with new parts. When replacing, put the positioning column 15 on the first mounting plate 13 into the positioning hole 16 on the second mounting plate 14, so that no deviation will occur when the bolts are tightened at the end.
