DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5, the utility model provides a technical solution: a new dry powder trolley valve structure, including: a convex handle 1, a valve stem 2, a first O-ring 3, an opening locating pin 4, a connector 5, a second O-ring 6, a first spring 7, a riser seat 8, a valve body 9, a connecting cap 10, a gasket 11, a spacer 12, a screw 13, a chain 14, a safety pin 15, a nozzle 16, a fixing block 17, a driving ring 18, a clamping block 19 and a second spring 20.

[0029] When using this new dry powder trolley valve structure, first as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the convex handle 1 is rotatably connected to the inner side of the upper section of the valve body 9 through a rivet. A valve stem 2 is installed below the convex handle 1, and the valve stem 2 is slidably connected inside the valve body 9 by the extrusion of the convex handle 1. And when the convex handle 1 rotates clockwise, the distance from the convex handle 1 to the valve stem 2 gradually decreases. A first O-ring 3 is fixed to the upper section of the valve stem 2, and the outer side of the first O-ring 3 is closely attached to the inner wall of the valve body 9. The opening locating pin 4 is installed inside the valve body 9, and the opening locating pin 4 is connected to the upper side of the connector 5, and the connector 5 is fixed to the middle of the left end of the valve body 9. The screw 13 is fixed to the rear end of the valve body 9, and the lower end of the chain 14 is fixedly connected to the screw 13, and the upper end of the chain 14 is fixed to the safety pin 15. The safety pin 15 is slidably connected to the inner sides of the convex handle 1 and the valve body 9 respectively;

[0030] Pull the safety pin 15 outward to make it leave the inner sides of the convex handle 1 and the valve body 9. At this time, the safety pin 15 is connected by the chain 14 to prevent it from detaching from the valve body 9. Then press the convex handle 1 downward clockwise to make it rotate. The convex handle 1 gradually presses the valve stem 2 downward. The first O-ring 3 improves the sealing performance between the valve stem 2 and the valve body 9 along the inner wall of the valve body 9, improving the safety performance;

[0031] The lower end of the valve stem 2 is fixed to the connecting cap 10, and the lower section of the valve stem 2 is fixed to the spacer 12. A sealing gasket 11 is installed on the outer side of the upper section of the connecting cap 10, and spacers 12 are fixed to the upper ends of both the connecting cap 10 and the sealing gasket 11. The second O-ring 6 is fixedly connected to the outer side of the lower section of the valve body 9, and the riser seat 8 is fixed to the lower end of the valve body 9 by threads. The connecting cap 10 is slidably connected to the inner part of the lower section of the valve body 9, and the sealing gasket 11 is in contact with the inclined surface of the inner wall of the valve body 9. The upper and lower ends of the first spring 7 are respectively fixedly connected to the connecting cap 10 and the riser seat 8;

[0032] When the valve stem 2 is pressed downwards, it squeezes the connection cap 10 and the gasket 11 downwards. At this time, the gasket 11 leaves the contact with the inner wall of the valve body 9, and the first spring 7 undergoes elastic deformation to generate elastic potential energy. The dry powder goes from the riser base 8 to the inside of the valve body 9, and then the dry powder sprays upwards from the connection head 5. When the convex handle 1 is released, the first spring 7 restores its elastic deformation to assist in pushing the connection cap 10 and the valve stem 2 upwards. The gasket 11 continues to closely adhere to the inner wall of the valve body 9, improving the safety of the valve, and the operation is simple, preparing for the next spraying. This method can speed up the fire extinguishing speed. When installing, the second O-ring 6 improves the sealing performance between the valve and the equipment.

[0033] As Figure 1 and Figure 4 shown, the nozzle 16 is fixed to the connection head 5 by threads, and the nozzle 16 is installed inside the fixing block 17. And the fixing block 17 is fixed to the outer side of the left section of the connection head 5. The driving ring 18 is sleeved outside the nozzle 16, and the driving ring 18 is slidably connected to the nozzle 16, the fixing block 17 and the clamping block 19 respectively. A second spring 20 is fixedly installed at the right end of the driving ring 18, and the right end of the second spring 20 is fixedly connected to the fixing block 17. And the second spring 20 passes through the inside of the fixing block 17. The clamping block 19 is slidably connected inside the fixing block 17, and the clamping block 19 is arranged at equal angles along the central axis of the nozzle 16. The clamping block 19 is snap-fitted with the groove opened inside the nozzle 16, and an inclined groove is opened inside the clamping block 19. And the driving ring 18 is slidably connected in the inclined groove;

[0034] Rotate the nozzle 16 into the inside of the connection head 5. Before installing the nozzle 16, push the driving ring 18 to the right. At this time, the driving ring 18 squeezes the second spring 20 to undergo elastic deformation. The driving ring 18 slides inside the clamping block 19, causing the clamping block 19 to slide outwards driven. After installing the nozzle 16 inside the connection head 5, release the driving ring 18. The second spring 20 restores its elastic deformation to push the driving ring 18 to reset. The driving ring 18 drives the clamping block 19 to reset. At this time, the clamping block 19 is stuck in the groove of the nozzle 16, completing the reinforcement of the nozzle 16 and the connection head 5, preventing the nozzle 16 from loosening from the connection head 5 due to rotation, and improving the safety performance during the use of the equipment.
