DETAILED DESCRIPTION

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-3As shown, the utility model provides a technical solution: a cast iron valve with anti-corrosion function, including a valve body 1, the bottom end of the valve body 1 is rotatably connected to a rotating shaft 14, the rotating shaft 14 passes through the valve body 1, and a baffle 15 is fixedly connected above the rotating shaft 14. Because the baffle 15 is provided, the handle 20 rotates to drive the rotating rod 19 to rotate, and the rotating rod 19 drives the baffle 15 to rotate. The rotation of the baffle 15 can control the water flow in the valve body 1, which is convenient for opening or blocking the water flow. The outer wall of the valve body 1 is provided with two through holes 12, and the outer wall of the baffle 15 is provided with two through holes 26. The size of the through hole 2 16 is adapted to the size of the through hole 1 2. Through the cooperation between the through hole 1 2 and the through hole 2 16, the through hole 2 16 rotates with the baffle 15, and the water flow through the baffle 15 can be limited through the through hole 2 16, which is convenient for controlling the inflow The water flow of the through hole 12, the valve body 1 is made of copper. Because the material of the valve body 1 is copper, this material is corrosion-resistant, which ensures the service life of the valve body 1. A limiting groove 17 is set on one side of the valve body 1. The number of limiting grooves 17 is three. Three limiting columns 18 are fixedly installed above the baffle block 15. The limiting columns 18 penetrate the limiting grooves 17. Through the cooperation between the limiting columns 18 and the limiting grooves 17, the rotating rod 19 is rotated by the handle 20. The rotating rod 19 drives the baffle block 15 to rotate, and the baffle block 15 drives the limiting columns 18 to rotate in the limiting grooves 17. The limiting groove 17 limits the baffle block 15 through the limiting columns 18, which prevents the baffle block 15 from rotating too much while facilitating the control of the water flow. A rotating rod 19 is fixedly installed above the baffle block 15. The rotating rod 19 penetrates the valve body 1, and a handle 20 is provided at the end of the rotating rod 19.

[0019] The outer wall of the valve body 1 is located at the position of the through hole 2 and is fixedly connected to two connecting pipes 3. The outer wall of the connecting pipe 3 is provided with a plurality of connecting grooves 4. The outer wall of the connecting pipe 3 is located on one side of the connecting groove 4 and is fixedly connected with a top plate 5. Because the top plate 5 is provided, when the connecting pipe 3 is separated from the sleeve 6, the sliding sleeve 12 squeezes the spring 8 to leave enough space in the sliding groove 7 of the sleeve 6, and the connecting pipe 3 is pulled to one side. The connecting pipe 3 drives the top plate 5 to move to one side, and the top plate 5 lifts up the card bead 10. After the card bead 10 is separated from the card connection with the connecting groove 4, it is convenient for the connecting pipe 3 to be separated from the sleeve 6. The outer wall of the connecting pipe 3 is sleeved with the sleeve 6, and a sliding groove 7 is provided on one side of the sleeve 6. The outer wall of the sleeve 6 is sleeved with a spring in the sliding groove 7. 8. Because of the spring 8, when the connecting pipe 3 is connected or separated from the sleeve 6, the sliding sleeve 12 slides and cooperates with the sleeve 6 to compress the spring 8, and the top plate 5 squeezes the card bead 10 to roll into the card groove 9, or the card plate 13 pushes the card bead 10 to roll into the card groove 9. After the sliding sleeve 12 is released, the spring 8 rebounds, and the sliding sleeve 12 can automatically reset, which is easy to operate. A card groove 9 is opened on one side of the sleeve 6, and a card bead 10 is arranged on the inner wall of the card groove 9. The position of the card bead 10 corresponds to the position of the connecting groove 4. A limiting block 11 is fixedly connected to one side of the sleeve 6, and the outer wall of the sleeve 6 is slidably connected with the sliding sleeve 12. The inner wall of the sliding sleeve 12 is fixedly connected with the card plate 13, and the position of the card plate 13 corresponds to the position of the card groove 9.

[0020] The working principle of the utility model is as follows: when in use, the handle 20 is turned, and the handle 20 drives the baffle 15 to rotate through the rotating rod 19, and the baffle 15 rotates on the inner wall of the valve body 1 through the rotating shaft 14, and the baffle 15 rotates to drive the through hole 2 16 to align with the through hole 1 2, and the baffle 15 drives the limiting column 18 to rotate on the inner wall of the limiting groove 17 during the rotation process. When the valve body 1 is replaced, by pulling the sliding sleeve 12, the sliding sleeve 12 squeezes the spring 8 to one side through the clamping plate 13, so that the spring 8 is in a compressed state, and during the movement of the clamping plate 13, there is enough space in the sliding groove 7 on one side of the sleeve 6, and the valve body 1 is pulled, and the valve body 1 drives the connecting pipe 3 to move to one side, and during the movement of the connecting pipe 3, the top plate 5 is driven to squeeze the card bead 10 upward, so that the card bead 10 moves in the card groove 9 and is disengaged from the card connection with the connecting groove 4. After the card bead 10 is disengaged from the card connection with the connecting groove 4, the valve body 1 can be removed for replacement and maintenance.
