[0021] The following will be combined with the attached embodiment of the utility model Figure 1-3 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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] Example:

[0023] like Figures 1 to 3 As shown, the utility model discloses a movable hard-sealed four-way directional valve, comprising a valve body 1, as shown in Figure 1 As shown, the valve body 1 includes four material passing pipes 11 and a valve core 12 , and a hard sealing ring 13 is arranged between the material passing pipe 11 and the valve core 12 .

[0024] A plurality of baffles 21 are circumferentially arranged in the feeding tube 11. The baffles 21 are fan-shaped plates and are rotatably arranged in the feeding tube 11. Correspondingly, a rotating shaft 23 is arranged in the feeding tube 11. The baffles 21 are rotatably connected to the rotating shaft 23. The end of the baffle 21 away from its outer arc surface is close to the axis of the feeding tube 11. When the fan-shaped surface of the baffle 21 is perpendicular to the axis of the feeding tube 11, the outer arc surface of the baffle 21 is just concentric with the feeding tube 11. A water hole 22 is provided on the baffle 21, and a resistance adjustment mechanism is arranged in the feeding tube 11.

[0025] The resistance adjustment mechanism specifically includes an elastic telescopic member 24 , and two ends of the elastic telescopic member 24 are respectively fixedly connected to the end of the spoiler 21 away from the outer arc surface thereof and the inner side wall of the material passing pipe 11 .

[0026] In addition, a stopper 25 is provided on the baffle plate 21 . The stopper 25 is provided on the end of the baffle plate 21 close to the axis of the material passing pipe 11 and is perpendicular to the sector surface of the baffle plate 21 .

[0027] In this structure, the connection point between the elastic telescopic member 24 and the spoiler 21 is set on the abutment rod 25, and the elastic telescopic member 24 is fixedly connected to the end of the abutment plate close to the spoiler 21.

[0028] The working principle of this structure is as follows: due to the existence of the resisting rod 25, the minimum flipping angle of the spoiler 21 is greater than 0°. Therefore, when the fluid flows into the feed pipe 11, the fluid can impact the spoiler 21 head-on, causing the spoiler 21 to flip and form resistance to the fluid. At the same time, the greater the fluid flow rate, the greater the flipping angle of the spoiler 21. When the fluid flow rate becomes smaller, the impact force received by the spoiler 21 becomes smaller, so the elastic telescopic member 24 can gradually pull the spoiler 21 back to its original position.

[0029] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
