DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-4 The utility model provides an embodiment: an anti-clogging manual gate valve, comprising: a valve body 1, a water inlet pipe 2 is arranged on one side of the valve body 1, a water outlet pipe 3 is arranged on the other side of the valve body 1, and the water inlet pipe 2 and the water outlet pipe 3 are all integrated with the valve body 1;

[0025] Also includes:

[0026] A valve cavity 17 is disposed inside the valve body 1. A valve plate 10 is disposed at the center of the valve cavity 17. Metal sheets 13 are disposed on both sides of the valve plate 10. A metal frame 12 is disposed at one end of the metal sheet 13. Inner grooves 14 are disposed on both sides of the valve plate 10.

[0027] The connecting seat 5 is arranged at the upper end of the valve body 1 . The upper end of the valve body 1 is provided with a valve cover 6 . The upper end of the valve plate 10 is provided with a threaded valve stem 7 .

[0028] When the valve plate 10 moves up and down, one end of the metal sheet 13 contacts the inner groove 14 on the surface of the valve plate 10 back and forth, thereby causing the metal sheet 13 to deform, thereby generating vibration, which has a shaking effect on the debris around the valve plate 10, thereby loosening it. Combined with the impact of water, the blockage can be unblocked. Continuously moving the valve plate 10 up and down will cause the metal sheet 13 to deform back and forth, making its vibration frequency fast, thereby avoiding blockage. There is no need to regularly disassemble the manual gate valve for cleaning, which improves the cleaning convenience and anti-blocking effect.

[0029] See also Figure 3 Sealing rings 11 are arranged on the outside of both sides of the edge of the valve plate 10, and two sealing rings 11 are arranged to improve the sealing performance of the contact between the valve plate 10 and the inner wall of the valve cavity 17.

[0030] See also Figure 1 A sealing seat 18 is provided at one end of the water inlet pipe 2 and the water outlet pipe 3, and the sealing seat 18 is welded and fixed to the water inlet pipe 2 and the water outlet pipe 3. A fixing flange 4 is provided on the outside of the sealing seat 18. The water inlet pipe 2 and the water outlet pipe 3 are fixed to the water pipe by external bolts of the fixing flange 4, and the sealing seat 18 is relied on to improve the sealing of the connection.

[0031] See also Figure 1 , 2 A connecting sleeve 15 is provided on the outside of the threaded valve stem 7, and the threaded valve stem 7 is threadedly connected to the connecting sleeve 15. A support frame 16 is provided between the two sides of the connecting sleeve 15 and the valve cover 6, and the two ends of the support frame 16 are respectively welded and fixed to the connecting sleeve 15 and the valve cover 6. A hand wheel 8 is provided above the connecting sleeve 15, and a nut is externally connected to the upper end of the hand wheel 8. When it is necessary to drain water, the hand wheel 8 is turned, and the threaded valve stem 7 moves upward along the connecting sleeve 15, driving the valve plate 10 to move upward, so that it does not contact the inner wall of the valve cavity 17, leaking out space, and water flows from the leaked space and is discharged along the outlet pipe 3.

[0032] See also Figure 1 Fixing bolts 9 are arranged on the upper ends of the four sides of the valve cover 6, and the valve cover 6 is threadedly connected to the connecting seat 5 through the fixing bolts 9, so that the valve cover 6 can be disassembled and fixed easily.

[0033] See also Figure 3 The metal sheet 13 and the metal frame 12 are both made of titanium alloy material. The metal sheet 13 and the metal frame 12 are welded and fixed. There are four metal sheets 13 and two metal frames 12. The titanium alloy material has elasticity and toughness, and has anti-corrosion effect, is not easy to be damaged, and improves the service life.

[0034] Working principle: When in use, the inlet pipe 2 and the outlet pipe 3 are fixed to the water pipe by the external bolts of the fixing flange 4. Water enters the valve body 1 from the inlet pipe 2 and is sealed and blocked by the valve plate 10. When it is necessary to drain water, the threaded valve stem 7 moves upward along the connecting sleeve 15 by turning the hand wheel 8, driving the valve plate 10 to move upward, so that it does not contact the inner wall of the valve cavity 17, leaking out space, and water flows from the leaked space and is discharged along the outlet pipe 3. After the drainage is completed, the hand wheel 8 is turned in the opposite direction, and the threaded valve stem 7 moves downward along the connecting sleeve 15, driving the valve plate 10 to move down to the initial position, thereby realizing The seal is present, which has the effect of blocking and interrupting the flow of water. When the valve plate 10 moves up and down, one end of the metal sheet 13 contacts the inner groove 14 on the surface of the valve plate 10 back and forth, thereby causing the metal sheet 13 to deform, thereby generating vibration, which has a shaking effect on the debris around the valve plate 10, thereby loosening it. Combined with the impact of water, the blockage effect can be achieved. Continuously moving the valve plate 10 up and down will cause the metal sheet 13 to deform back and forth, making its vibration frequency fast, thereby avoiding blockage, and there is no need to regularly disassemble the manual gate valve for cleaning, which improves the cleaning convenience and anti-blocking effect.
