[0022] Refer to Figures 1-5This utility model discloses a low-noise safety valve, comprising: a valve body 3; a fixing plate 8 and a guide box 21 fixedly connected to the side surface of the valve body 3; the fixing plate 8 fixedly connected to the side surface of the guide box 21; a fixing block 10 fixedly connected to the side surface of the fixing plate 8; the guide box 21 penetrating the valve body 3 and extending into the valve body 3; a moving groove 20 provided inside the valve body 3; a sealing plate 9 provided at the end of the guide box 21 away from the valve body 3; the sealing plate 9 and the fixing plate 8 being detachably connected by bolts 11; a sealing block fixedly connected to the side surface of the sealing plate 9, the sealing block being located within the moving groove 20; and a guide block 18 provided inside the valve body 3. A connecting block 19 is slidably connected to the inside of block 18. A second slot 30 is provided on the connecting block 19. A locking block 29 is slidably connected in the second slot 30. A valve disc 14 is fixedly connected to the lower surface of the locking block 29. A movable groove 22 and a storage groove 26 are provided in the connecting block 19. A second spring 23 is fixedly connected in the movable groove 22. A movable plate 24 is fixedly connected to the other end of the spring 23. The movable plate 24 is slidably connected to the movable groove 22. A connecting post 25 is fixedly connected to the lower surface of the movable plate 24. A fixing ball 27 is fixedly connected to the lower surface of the connecting post 25. A first slot 28 is provided on the locking block 29. The fixing ball 27 is located in the first slot 28.

[0023] Specifically, the sealing plate 9 is removed, and the valve disc 13 connected with the locking block 29 is inserted into the moving groove 20. The locking block 29 is pushed into the valve body 3 by the push block with the sealing block that is used in conjunction with the moving groove 20. Under the action of the guide box 21, the valve disc 14 that needs to be replaced is pushed away from the connecting block 19 and replaced. Under the action of the fixing ball 27 and the locking groove 28 on the locking block 29, the locking block 29 is locked and fixed. Then, on the other side, the locking block 29 is pulled out from the valve body 3 by the sealing block with the magnet.

[0024] A discharge pipe 4 is fixedly connected to the side surface of the valve body 3. A connecting seat 2 5 is fixedly connected to the side surface of the discharge pipe 4. A connecting seat 1 is fixedly connected to the side surface of the valve body 3. A feed inlet 12 is provided on the connecting seat 1. Both the connecting seat 1 and the connecting seat 2 5 are provided with fixing holes 2. A rubber block is provided on the side surface of the valve body 3. A valve seat 13 is fixedly connected to the upper surface of the connecting seat 1. A valve disc 14 is located directly above the valve seat 13. A top plate 31 is detachably connected to the upper surface of the valve body 3 by another bolt 11. A valve cover 6 is fixedly connected to the upper surface of the top plate 31. A sleeve 7 is fitted on the valve cover 6. A screw 15 is fixedly connected to the upper surface of the connecting block 19. The screw 15 passes through the valve cover 6 and extends to the upper surface of the valve cover 6. A spring 16 is provided inside the valve cover 6. The spring 16 is located on the side surface of the screw 15. A rotating block 17 is rotatably connected to the valve cover 6. The screw 15 and the rotating block 17 are threadedly connected.

[0025] Specifically, when replacing valve disc 14, the pressure of valve disc 14 is adjusted by rotating screw 15 and spring 16, thereby reducing the pressure and lifting valve disc 14 to facilitate subsequent replacement. Rotating block 17 facilitates the rotation of screw 15. Connecting seat 1 and connecting seat 2 facilitate connection with pipeline. Fixing hole 2 facilitates fixation. The rubber block facilitates noise reduction, making the overall noise during operation lower. Sleeve 7 protects components such as screw 15.

[0026] Working principle: In use, first, the locking block 29 is placed into the moving groove 20. Since the valve disc 14 is fixedly connected to the locking block 29, the valve disc 14 enters the moving groove 20. Then, the locking block 29 is pushed into the inner side of the moving groove 20 by the push block with a sealing block that is used in conjunction with the moving groove 20. Under the action of the sealing block, leakage is prevented. Then, by rotating the screw 15, the compression of the spring 16 is adjusted, thereby reducing the pressure on the valve disc 14. Under the action of the pressure in the valve seat 13, the valve disc 14 is lifted up. The valve disc 14 in the valve body 3 rises, and under the action of the guide box 21, the upper surface of the valve disc 14 is aligned with the guide box 21. The lower surface is attached to the groove, making the moving groove 20 connected with the second groove 30. Then, the push continues, causing the locking block 29 to enter the second groove 30 and squeezing the fixed ball 27 into the receiving groove 26. When the first groove 28 on the locking block 29 moves to directly below the fixed ball 27, the second spring 23 engages the locking block 29 and stops the push. At this time, the push block with the sealing block is still outside the valve body 3. Meanwhile, the valve disc in the valve body 3 has entered the moving groove 20 on the other side. Then, the screw 15 is rotated using the same principle to increase the pressure of the valve disc 14. Finally, the locking block 29 is pulled out by the sealing block with the magnet.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
