The drive disk 11 is slidably connected to the inner wall of the limiting cylinder 8, and the drive disk 11 is fixedly connected to the right side of the connecting shaft 9. The spring 12 is fixedly connected to the inner wall of the limiting cylinder 8, and the spring 12 is fixedly connected to the left side of the drive disk 11, which is used to drive the non-return mechanism to rebound and move, thereby improving the non-return stability. A limiting mechanism is arranged inside the limiting cylinder 8, and the limiting mechanism consists of a limiting slide 13 and a limiting slider 14. There are multiple limiting slides 13, and multiple limiting slides 13 are all arranged inside the limiting cylinder 8, which are used to connect multiple limiting sliders 14, thereby improving the limiting stability. The limiting slide 1 3 is opened on the inner wall of the limiting cylinder 8, the limiting slider 14 is slidably connected with the inner wall of the limiting slide groove 13, and the inner wall of the limiting slider 14 is fixedly connected with the surface of the driving disk 11, which is used to limit the elastic driving component, thereby improving the movement stability. A sealing component is arranged inside the limiting ring 6, and the sealing component consists of a sealing ring 15 and a sealing disk 16. The sealing ring 15 is fixedly connected with the inner wall of the limiting ring 6, and the sealing disk 16 is circular in shape, and the sealing disk 16 is made of silicone material. The sealing disk 16 made of silicone material has stronger resilience, thereby improving the stability of the extrusion seal. The sealing disk 16 is fixedly connected to the right side of the check cover 10, and the sealing disk 16 overlaps the sealing ring 15, for performing the check sealing process. To avoid leakage of backflow water, the water inlet pipe 2 and the water outlet pipe 4 are connected to the water treatment pipeline through the first flange 3 and the second flange 5. After the water flows into the check pipe 1 from the water inlet pipe 2, the impact force pushes the check mechanism and the sealing component to move to the left, and at the same time squeezes the elastic drive component to carry out water delivery. When the water delivery work is stopped, the rebound force of the elastic drive component drives the check mechanism and the sealing component to reset, and the sealing check work can be carried out through the extrusion deformation of the sealing component, thereby achieving the goal of facilitating improving the check sealing and stability of the check device, and avoiding the problem that the existing check device is easily loosened due to the influence of backflow water, thereby causing poor check sealing and stability.

[0021] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0022] When in use: first, the water inlet pipe 2 and the water outlet pipe 4 are connected to the water treatment pipeline through the first flange 3 and the second flange 5. After the water flows into the check pipe 1 through the water inlet pipe 2, it flows to the left along the inner wall of the limiting ring 6. The impact force of the water flow pushes the sealing disk 16 and the check cover 10 to move to the left and disengage from the sealing ring 15. The movement of the check cover 10 drives the connecting shaft 9 and the driving disk 11 to slide to the left along the inner wall of the limiting cylinder 8. The movement of the driving disk 11 drives the limiting slider 14 to slide along the inner wall of the limiting slide groove 13 to limit the sliding trajectory of the driving disk 11. At the same time, the movement of the driving disk 11 squeezes the spring 12, so that the water flow can be discharged through the water outlet pipe 4. When the water supply work is stopped and the impact force of the water flow is reduced, the rebound force of the spring 12 pushes the driving disk 11 and the connecting shaft 9 to slide and reset, and at the same time drives the check cover 10 and the sealing disk 16 to rebound and reset to contact the sealing ring 15. The sealing check work can be performed through the extrusion deformation of the sealing disk 16 and the sealing ring 15.

[0023] To summarize, the water treatment check device connects the water inlet pipe 2 and the water outlet pipe 4 to the water treatment pipeline through the first flange 3 and the second flange 5. After the water flows into the check pipe 1 from the water inlet pipe 2, the impact force pushes the check mechanism and the sealing component to move to the left, and at the same time squeezes the elastic drive component to carry out water delivery. When the water delivery is stopped, the rebound force of the elastic drive component drives the check mechanism and the sealing component to reset, and the sealing check can be carried out through the extrusion deformation of the sealing component, thereby achieving the goal of facilitating the improvement of the check sealing and stability of the check device, avoiding the problem that the existing check device is easily loosened due to the influence of backflow water, thereby resulting in poor check sealing and stability, and is used to solve the problems raised in the above-mentioned background technology.
