[0022] Next, in combination with the specification drawings of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 and Figure 2 An embodiment provided by the present utility model: a portable dry powder valve that is convenient for disassembly, replacement and installation, including a valve body 1. The inner wall of the valve body 1 is fixedly connected with a vertical pipe seat 2. The inner wall of the valve body 1 is slidably connected with a sliding valve stem 3. The outer wall of the sliding valve stem 3 is fixedly connected with a valve stem cap 4. The lower surface of the valve stem cap 4 is fixedly connected with a first spring 5. The outer wall of the first spring 5 is slidably connected to the inner wall of the vertical pipe seat 2. The upper surface of the valve stem cap 4 is fixedly connected with a sealing flat gasket 10. The upper surface of the sealing flat gasket 10 is fixedly connected with a gasket 11. The outer wall of the valve stem cap 4 is slidably connected to the inner wall of the vertical pipe seat 2. A rivet 6 is fixedly connected inside the valve body 1. The outer wall of the rivet 6 is rotatably connected with a lifting handle 9. The inside of the lifting handle 9 is slidably connected with a safety pin 7. The inner wall of the safety pin 7 is slidably connected with a rubber chain 8. The outer wall of the rubber chain 8 is slidably connected to the inner wall of the lifting handle 9. A connecting component is provided on the outer wall of the vertical pipe seat 2, and the connecting component is used for auxiliary fixation.

[0024] Specifically, by pressing the lifting handle 9, the sliding valve stem 3 is driven to slide inside the valve body 1. The first spring 5 in the vertical pipe seat 2 is compressed by the valve stem cap 4, so that the sealing flat gasket 10 and the gasket 11 are separated from the inner wall of the valve body 1, and then the dry powder will quickly spray out from the valve body 1. The rubber chain 8 can connect the safety pin 7 and the lifting handle 9, and the rivet 6 plays a role in connecting the lifting handle 9 of the valve body 1.

[0025] Refer to Figure 3 The connecting component includes a connecting belt 22. The inner wall of the connecting belt 22 is fixedly connected to the outer wall of the vertical pipe seat 2. A block 12 is fixedly connected to the left outer wall of the connecting belt 22.

[0026] Specifically, the connecting belt 22 plays a role in fixing the block 12.

[0027] Referring to Figure 3 and Figure 4

[0028] Specifically, after placing the connecting frame 18 on the clamping block 12, pulling the handle 20 drives the sliding block 17 to slide on the connecting rod 15, thereby compressing the second spring 16. The sliding groove 21 plays a role in limiting the movement of the connecting frame 18. The connecting shaft 19 plays a role in connecting the handle 20 of the first fixing block 13, and the connecting belt 22 plays a role in fixing the second fixing block 14.

[0029] Working principle: When the valve needs to be used, first pull out the safety pin 7 from the lifting handle 9. The safety pin 7 can be connected to the lifting handle 9 through the rubber chain 8. The rivet 6 plays a role in connecting the lifting handle 9 of the valve body 1. By pressing the lifting handle 9, the lifting handle 9 drives the sliding valve stem 3 to slide on the inner wall of the valve body 1, thereby compressing the first spring 5 in the riser seat 2 through the valve stem cap 4. At this time, the sealing gasket 10 and the gasket 11 are separated from the inner wall of the valve body 1, and the dry powder will quickly spray out from the valve body 1. After placing the connecting frame 18 on the clamping block 12, pulling the handle 20 drives the sliding block 17 to slide on the connecting rod 15, thereby compressing the second spring 16. The sliding groove 21 plays a role in limiting the movement of the connecting frame 18. The connecting shaft 19 plays a role in connecting the handle 20 of the first fixing block 13, and the connecting belt 22 plays a role in fixing the second fixing block 14, thereby fixing and connecting the valve. The device has fast start-up and operation, achieving the effect of shortening the response time and facilitating disassembly and replacement of the valve.
