DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Example

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution: a high sealing valve, including a fixing component 101, a limiting component 201 and a main body component 301;

[0023] The fixing assembly 101 includes a mounting plate 10, a slide groove 11, a slider 12, a first damper 13, a first spring 14, a fixing plate 15, a positioning pin 16, a second damper 17 and a second spring 18;

[0024] A slide groove 11 is provided at the top of the mounting plate 10, and the bottom of the slider 12 is slidably connected to the inside of the slide groove 11. One end of the first damper 13 is fixedly connected to the top of the slider 12, and the other end of the first damper 13 is fixedly connected to the bottom of the fixing plate 15. The outer wall of the first damper 13 is sleeved with a first spring 14, and a positioning pin 16 is installed at the bottom of the fixing plate 15.

[0025] In this embodiment, specifically: one end of the second damper 17 is fixedly connected to the inner wall of the slide groove 11, and the other end of the second damper 17 is fixedly connected to one side of the slider 12. The outer wall of the second damper 17 is sleeved with a second spring 18. When the valve switch 20 needs to be fixed, the slider 12 is moved to make the fixing plate 15 move in the slide groove 11, so that the positioning pin 16 moves accordingly, and the fixing plate 15 is pulled up to make the positioning pin 16 move to the top of the limiting hole 26. The fixing plate 15 is released, and the first spring 14 drives the fixing plate 15 to reset, so that the positioning pin 16 is stuck in the limiting hole 26, thereby fixing the valve switch 20 to prevent external factors from accidentally touching the valve switch 20 and affecting the sealing of the valve body 30.

[0026] In this embodiment, specifically: the limit assembly 201 includes a valve switch 20, a ratchet 21, a pawl 22, a cylinder 23, a valve core 24, a first sealing gasket 25 and a limit hole 26. The inner wall of the mounting plate 10 is mounted on the outer wall of the valve switch 20. The outer wall of the valve switch 20 is mounted with a ratchet 21. The bottom of the pawl 22 is mounted on the top of the mounting plate 10. The outer wall of the cylinder 23 is fixedly connected to the top of the mounting plate 10. The piston rod of the cylinder 23 is fixedly connected to one side of the pawl 22. The arrangement of the ratchet 21 and the pawl 22 can prevent the staff from operating incorrectly, resulting in the wrong direction of the valve switch 20. When the valve switch 20 needs to be closed, the pawl 22 is driven to move by controlling the cylinder 23 so that the pawl 22 is disengaged from the ratchet 21. At this time, the valve switch 20 is turned to close.

[0027] In this embodiment, specifically: a valve core 24 is installed at one end of the valve switch 20, a first sealing gasket 25 is installed on the top of the valve core 24, a limiting hole 26 is opened on the top of the ratchet 21, and the outer wall of the ratchet 21 is meshed and connected to the outer wall of the pawl 22. By installing the first sealing gasket 25 on the valve core 24, a sealing effect is achieved on the valve body 30.

[0028] In this embodiment, specifically: the main body assembly 301 includes a valve body 30, a water inlet 31, a water outlet 32, a first sealing plate 33 and a second sealing plate 34;

[0029] Among them, the bottom of the mounting plate 10 is connected to the top of the valve body 30 by screws, a water inlet 31 is provided at one end of the valve body 30, and a water outlet 32 ​​is provided at the other end of the valve body 30. A first sealing plate 33 is installed on the inner top wall of the valve body 30, and a second sealing plate 34 is installed on the inner bottom of the valve body 30. The cooperation of the first sealing plate 33, the second sealing plate 34 and the first sealing gasket 25 increases the sealing performance of the valve body 30.

[0030] Working principle: Install the device as a whole to the specified position. When the valve switch 20 needs to be fixed, the slider 12 is moved to move the fixing plate 15 in the slide groove 11, so that the positioning pin 16 moves accordingly. The fixing plate 15 is pulled up to move the positioning pin 16 to the top of the limiting hole 26. The fixing plate 15 is released, and the first spring 14 drives the fixing plate 15 to reset, so that the positioning pin 16 is stuck in the limiting hole 26, thereby fixing the valve switch 20 to prevent external factors from accidentally touching the valve switch 20 and affecting the sealing of the valve body 30. When the valve body 30 needs to be closed, the fixing plate 15 is pulled up to make the positioning pin 16 The first spring 14 is then moved out of the limiting hole 26, and a reverse thrust is generated by the second spring 18, driving the slider 12 to reset, so that the slider 12 drives the fixing plate 15 to reset. At this time, the first spring 14 contracts, so that the first spring 14 drives the fixing plate 15 to move downward, so as to prevent the fixing plate 15 from affecting the rotation of the ratchet 21. Then the cylinder 23 is controlled to drive the pawl 22 to move, so that the pawl 22 is disengaged from the ratchet 21. At this time, the valve switch 20 is turned to close. The arrangement of the ratchet 21 and the pawl 22 can prevent the staff from operating incorrectly, resulting in the wrong direction of the valve switch 20, thereby increasing the stability of the valve switch 20.
