Detailed implementation manner
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] Refer to Figures 1 - 3 As shown in the figure, an embodiment provided by the present invention: A portable dry powder housing valve includes a bottle body 1. A mounting seat 6 is fixedly arranged at the outlet of the bottle body 1. A valve housing 3 is fixedly connected to the circumferential side of the mounting seat 6. Valve housing chutes 16 are symmetrically arranged inside the valve housing 3. A slide block 17 is slidably connected inside the valve housing chutes 16. Limiting posts 18 are fixedly connected to the opposite sides of the slide block 17. A valve body 7 is fixedly connected to the top of the mounting seat 6. Fixed blocks 10 are symmetrically and fixedly connected to the top of the valve body 7. A rotating shaft 15 is rotatably connected to the opposite sides of the fixed blocks 10 through bearings. A press handle 5 is fixedly connected to the outer wall of the rotating shaft 15. Limiting grooves 8 are evenly arranged at the bottom of the press handle 5. The limiting grooves 8 are matched with the limiting posts 18.
[0025] Specifically, by installing the valve housing 3 on the mounting seat 6, the contact area between the valve body 7 and corresponding accessories and the outside is reduced, thereby preventing the valve body and corresponding accessories from rusting due to oxidation, etc., and reducing the leakage of the fire extinguishing agent in the fire extinguisher or the situation where it cannot be timely during fire extinguishing. By pushing the limiting posts 18, the slide block 17 is driven to slide inside the valve housing chute 16. The press handle 5 can be limited by the limiting grooves 8 at the bottom of the press handle 5 to prevent accidental touch during non-fire extinguishing, resulting in the ejection of the fire extinguishing agent in the bottle body 1 and causing accidents. It realizes the limitation of the fire extinguisher without a safety pin, prevents the situation where the safety pin of the fire extinguisher cannot be pulled out due to rust and corrosion, and reduces the situation where the best fire extinguishing opportunity is missed due to the inability to pull out the safety pin, improving the practicability.
[0026] Inside the valve body 7, a valve body groove 12 is symmetrically arranged, and a return spring 13 is fixedly connected to the bottom of the valve body groove 12; a connecting plate 14 is fixedly connected to the top of the valve cover 3, and a valve rod 11 is fixedly connected to the middle of the connecting plate 14; a pressing block 9 is arranged at the bottom of the pressing handle 5, and the pressing handle 5 is located on the side opposite to the fixed block 10; the top of the valve rod 11 passes through the middle of the valve body 7 and is slidably connected to the bottom of the pressing block 9; a through hole 19 is arranged inside the valve body 7, one end of the through hole 19 is connected to the inside of the bottle body 1 through a mounting seat 6, and the inside of the through hole 19 matches the valve body 7; an outlet pipe 4 is fixedly connected to one side of the valve body 7, and the inside of the outlet pipe 4 is connected to the other end of the through hole 19; a pressure gauge 2 is arranged on one side of the valve body 7.
[0027] Specifically, by pressing the pressing handle 5, the pressing block 9 drives the valve rod 11 to move downward, so that the inside of the through hole 19 is connected to the inside of the outlet pipe 4, so that the fire extinguishing agent in the bottle body 1 is ejected from the outlet pipe 4 for fire extinguishing. After the fire extinguishing is completed, the pressing handle 5 is released, and then the return spring 13 drives the connecting plate 14 to move upward, so that the valve rod 11 closes the through hole 19 again to prevent the fire extinguishing agent from leaking.
[0028] Working principle: When in use, by pressing the pressing handle 5, the pressing block 9 drives the valve rod 11 to move downward, so that the inside of the through hole 19 is connected to the inside of the outlet pipe 4, so that the fire extinguishing agent in the bottle body 1 is ejected from the outlet pipe 4 for fire extinguishing. After the fire extinguishing is completed, the pressing handle 5 is released, and then the return spring 13 drives the connecting plate 14 to move upward, so that the valve rod 11 closes the through hole 19 again to prevent the fire extinguishing agent from leaking. By installing the valve cover 3 on the mounting seat 6, the contact area between the valve body 7 and the corresponding accessories and the outside is reduced, so that oxidation and rusting of the valve body and the corresponding accessories can be prevented, thereby reducing the leakage of the fire extinguishing agent of the fire extinguisher or the situation where it cannot be timely during fire extinguishing. By pushing the limit post 18, the slider 17 is driven to slide inside the valve cover chute 16. The limit groove 8 at the bottom of the pressing handle 5 can limit the pressing handle 5 to prevent accidental touch when not extinguishing the fire, resulting in the ejection of the fire extinguishing agent in the bottle body 1 and causing an accident. It realizes the restriction of the fire extinguisher without a safety pin, prevents the situation where the safety pin of the fire extinguisher cannot be pulled out due to rust and corrosion, and reduces the situation where the best fire extinguishing opportunity is missed due to the inability to pull out the safety pin.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
