[0024] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0025] Please see Figures 1-7 A first embodiment of a piercing nozzle includes a valve body 1. A sealing platform 4 is provided at the center of the top surface of the valve body 1. A pressure rod 41 is provided at the center of the sealing platform 4, penetrating the sealing platform 4. A pressure plate 46 is provided at one end of the pressure rod 41 outside the valve body 1. A pin 47 is provided below the pressure plate 46, penetrating the pressure rod 41. A lifting platform 42 is coaxially provided below the pressure rod 41. A striking pin 44 is provided at the other end of the lifting platform 42. The striking pin 44 has a hollow structure, and a through groove 45 is provided on the side of the striking pin 44. The through groove 45 passes through one side of the striker 44; the center of the valve body 1 is open, and one end of the valve body 1 is sealed by the sealing platform 4. The pressure rod 41 can move inside the sealing platform 4. The pressure plate 46 pushes the pressure rod 41 down to move inside the valve body 1, and drives the lifting platform 42 to move synchronously. When the lifting platform 42 is pushed to move, the lifting platform 42 causes the striker 44 at the other end to move linearly inside the valve body 1; the through groove 45 connects the internal cavity of the striker 44 to the outside; the pin 47 prevents manual start-up when not necessary.
[0026] Please see Figures 1-7The bottom surface of the pressure rod 41 contacts the top surface of the lifting platform 42; a second sealing ring 43 is provided on the side of the lifting platform 42; the valve body 1 is vertically divided into multiple inner diameters of different sizes, the inner diameter of the lifting platform 42 inside the valve body 1 is the same as the diameter of the lifting platform 42, and the inner diameter of the valve body 1 below the lifting platform 42 is slightly larger than the diameter of the striking pin 44; the friction between the lifting platform 42 and the inner diameter of the valve body 1 is increased by the second sealing ring 43, preventing the lifting platform 42 from driving the striking pin 44 downward under the action of gravity. Pressure can be applied to the pressure plate 46 to make the pressure rod 41 push the lifting platform 42 downward while driving the striking pin 44 downward. At the same time, when the lifting platform 42 is located at the junction of the inner diameters inside the valve body 1, the pressure rod 41 and the lifting platform 42 are released from contact, preventing the subsequent movement of the pressure rod 41 from driving the striking pin 44 to move synchronously.
[0027] Please see Figures 1-7 A mounting platform 3 is provided on one side of the top surface of the valve body 1. The center of the mounting platform 3 coincides with the center of the partial pressure rod 41 between the sealing platform 4 and the lifting platform 42. A gunpowder ball 34 is provided at the center of the interior of the mounting platform 3. A first sealing ring 36 is provided at the connection between the mounting platform 3 and the valve body 1. The mounting platform 3 and the valve body 1 are sealed together by the first sealing ring 36 on the mounting platform 3. The gunpowder ball 34 in the mounting platform 3 is detonated by electricity, which increases the air pressure at the center of the partial pressure rod 41 between the sealing platform 4 and the lifting platform 42, thereby pushing the lifting platform 42 to move downward.
[0028] Please see Figures 1-7 An electric wire 31 is provided on the outside of the mounting platform 3, and a protective layer 32 is provided on the outside of the electric wire 31. A power-conducting head 33 is provided at the other end of the electric wire 31. A stabilizing block 35 is provided inside the mounting platform 3. One end of the stabilizing block 35 is connected to the gunpowder ball 34, and the other end of the stabilizing block 35 is connected to the electric wire 31. An electrical signal is transmitted to the gunpowder ball 34 through the power-conducting head 33, and the electrical signal of the power-conducting head 33 is transmitted to the gunpowder ball 34 through the electric wire 31 to control the detonation of the gunpowder ball 34. The protective layer 32 is used to reinforce the electric wire 31, and the stabilizing block 35 is used to stably connect the gunpowder ball 34 and the electric wire 31.
[0029] Please see Figures 1-7A connecting platform 11 is provided on the lower side of the valve body 1 adjacent to the mounting platform 3. A water inlet 2 is provided at the center of the connecting platform 11. The water inlet 2 is connected to the interior of the valve body 1, and the center of the water inlet 2 coincides with the center of the through groove 45. A first sealing block 5 is provided below the through groove 45, and a second sealing block 51 is provided below the first sealing block 5. A baffle 52 is provided between the first sealing block 5 and the second sealing block 51. The water inlet 2 is aligned with the through groove 45 on the striker 44, so that the water inlet 2 is connected to the striker 44, which facilitates water to enter the striker 44 from the water inlet 2 through the through groove 45. The first sealing block 5 and the second sealing block 51 are annular structures. The annular positions inside the first sealing block 5 and the second sealing block 51 coincide and coincide with the center of the striker 44. The baffle 52 is fixed by the first sealing block 5 and the second sealing block 51, and the annular positions on the first sealing block 5 and the second sealing block 51 are sealed by the baffle 52.
[0030] Please see Figures 1-7 The bottom of the valve body 1 is provided with a water outlet 21, which is coaxially arranged with the sealing platform 4; the bottom of the valve body 1 is connected to the outside through the water outlet 21.
[0031] Please see Figures 1-7 A second embodiment of a piercing nozzle includes a valve body 1, which comprises an upper valve body 12 and a lower valve body 13. The upper valve body 12 and the lower valve body 13 are interconnected. A sealing gasket 14 is provided inside the upper valve body 12 at the connection between the upper valve body 12 and the lower valve body 13, and the striking pin 44 penetrates the sealing gasket 14. The valve body 1 can be configured as a split structure, consisting of an upper valve body 12 and a lower valve body 13. A connecting platform 11 is installed on the upper valve body 12, and the sealing gasket 14 at the connection between the upper valve body 12 and the lower valve body 13 provides a sealed connection.
[0032] During use, water pipes are connected to inlet 2 and outlet 21 respectively. Water flows into the valve body 1 from inlet 2. When a fire occurs, the energizer 33 transmits an electrical signal to the gunpowder ball 34 in the mounting platform 3 and detonates the gunpowder ball 34. The high-pressure gas generated when the gunpowder ball 34 explodes pushes the sealing platform 4 downwards on its own, pushing the striker 44 to pierce the baffle 52, so that the through groove 45 is connected to the outlet 21. Water flows out from the striker 44, increasing the outflow speed and total amount of water and improving the fire extinguishing efficiency. When the electrical signal cannot be transmitted to the gunpowder ball 34, the pin 47 can be removed to apply pressure to the pressure plate 46 to complete the piercing and extinguishing. After the valve body 1 is set as a segmented structure, the sealing platform 4 structure inside the lower valve body 13 can be reset after movement, and the gunpowder ball 34 can be replaced. Thus, the lower valve body 13 can be reused, and only the upper valve body 12 needs to be replaced, reducing the operating cost.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
