[0002] At present, fire extinguishing devices are widely used in equipment and facilities such as computer rooms, transformer rooms, distribution cabinets, battery boxes, battery cabinets, charging and swapping cabinets, energy storage cabins, communication cabinets, and mobile communication base stations. The function of the container valve in the fire extinguishing device is to seal the fire extinguishing agent in normal times and release the fire extinguishing agent when it is opened in case of fire. However, most of the container valves used in existing fire extinguishing devices pierce the sealing diaphragm with a needle under the action of the driving device. When the valve is opened, part of the fire extinguishing agent leaks from the punctured hole in the sealing diaphragm until the fire extinguishing agent is sprayed. This causes the loss and waste of fire extinguishing agent, especially when used on small-capacity cylinders or in places where multiple interval sprayings are required at one time. There is a safety hazard of fire extinguishing failure due to the loss of fire extinguishing agent. To this end, we propose a multifunctional fire extinguishing device container valve assembly to solve the above problem. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4 The utility model provides an embodiment of a multifunctional fire extinguishing device container valve assembly, comprising a control valve body 1, an instrument 2 is movably installed on the left side of the lower end of the control valve body 1, a nozzle 3 is provided on the right side of the lower end of the control valve body 1, a movable valve 4 is movably installed in the control valve body 1, a spring 5 is installed in the control valve body 1, the spring 5 is located between the upper inner wall of the control valve body 1 and the upper side of the movable valve 4, a first nut 6 is installed on the upper end of the control valve body 1, a second nut 7 is movably installed on the first nut 6, an electromagnetic valve 8 is installed on the upper end of the second nut 7, a sealing plate 9 is provided at the connection between the first nut 6 and the second nut 7, a plurality of exhaust ports 17 are annularly provided on the second nut 7, and a sealing assembly is provided in the second nut 7. The device drives the sealing assembly to slide in the second nut 7 through the electromagnetic valve 8, making the air pressure at the upper end of the control valve body 1 greater than the air pressure at the lower end, and then the movable valve 4 and the spring 5 slide in the control valve body 1, so that the gas in the storage bottle is discharged from the nozzle 3 to extinguish the fire.

[0019] Furthermore, a cross-line gap is opened at the center of the sealing piece 9. The sealing piece 9 is made of rubber material. According to the shape of the sealing piece 9, when the sealing assembly is removed from the sealing piece 9, the air pressure at the upper end of the control valve body 1 will push the sealing piece 9 open, and then the air pressure will flow out from the cross-line gap at the center of the sealing piece 9.

[0020] Furthermore, the sealing assembly includes a screw 10 and a pressure plate 11. The screw 10 is installed on the lower side of the solenoid valve 8, and the pressure plate 11 is movably installed in the second nut 7. A fixed block 12 is fixedly installed on the upper side of the pressure plate 11, and a threaded groove 13 is provided in the fixed block 12. The lower end of the screw 10 is inserted in the threaded groove 13. The inner wall of the second nut 7 is annularly installed with multiple groups of protrusions 14, and the outer wall of the pressure plate 11 is provided with multiple groups of grooves 15. This structure drives the screw 10 to rotate through the solenoid valve 8 to slide the pressure plate 11 and the fixed block 12 upward in the second nut 7, and removes the pressure plate 11 from the sealing plate 9, so that the air pressure at the upper and lower ends of the control valve body 1 can be unbalanced, and then the movable valve 4 and the spring 5 slide open in the control valve body 1, and the gas in the storage bottle is discharged from the nozzle 3 to extinguish the fire.

[0021] Furthermore, the inner walls of the multiple groups of protrusions 14 and the multiple groups of grooves 15 are both semicircular, and the multiple groups of protrusions 14 are lower than half the height of the inner wall of the second nut 7. This structure allows the pressure plate 11 to move upward according to the shape and height of the multiple groups of protrusions 14 to move the multiple groups of grooves 15 away from the upper end of the multiple groups of protrusions 14, so that the air pressure in the upper end of the control valve body 1 flows upward and is discharged from the multiple groups of grooves 15 on the outer wall of the pressure plate 11.

[0022] Furthermore, the upper ends of the multiple groups of protrusions 14 are lower than the openings of the multiple groups of exhaust ports 17, and the space on the upper side of the openings of the multiple groups of exhaust ports 17 in the second nut 7 is greater than the height of the upper and lower sides of the pressure plate 11 and the fixed block 12. This structure is based on the upper end height of the multiple groups of protrusions 14 and the position of the multiple groups of exhaust ports 17, so that after the pressure plate 11 is removed from the multiple groups of protrusions 14, the pressurized gas flowing out from the grooves 15 on the outer wall of the pressure plate 11 is discharged from the multiple groups of exhaust ports 17. Conversely, the pressure plate 11 moves downward to tightly fit the multiple groups of grooves 15 with the multiple groups of protrusions 14, so that the inside of the second nut 7 on the lower side of the pressure plate 11 can be sealed.

[0023] Furthermore, a sealing gasket 16 is glued to the lower side of the pressure plate 11, and the sealing gasket 16 is tightly fitted with the upper side of the sealing sheet 9. The sealing gasket 16 is made of rubber material. This structure is based on the sealing gasket 16 glued to the lower side of the pressure plate 11, so that when the pressure plate 11 and the sealing sheet 9 are fitted, the sealing gasket 16 fills the space between the pressure plate 11 and the sealing sheet 9, thereby improving the sealing effect when the pressure plate 11 and the sealing sheet 9 are fitted.

[0024] Working principle: When using control valve body 1, Figure 2 、 Figure 3 and Figure 4As shown, the solenoid valve 8 drives the screw 10 to rotate, and the rotation of the screw 10 drives the pressure plate 11 and the fixed block 12 to slide upward in the second nut 7. The pressure plate 11 and the fixed block 12 slide upward and move away from the sealing piece 9, and the pressure plate 11 slides on the multiple groups of protrusions 14 through the multiple groups of grooves 15. The multiple groups of grooves 15 on the pressure plate 11 slide away from the upper ends of the multiple groups of protrusions 14, and then the air pressure at the upper and lower ends of the control valve body 1 is unbalanced, and the movable valve 4 and the spring 5 slide upward in the control valve body 1. The air pressure in the upper end of the control valve body 1 will push open the sealing piece 9, and the pressurized air flow will flow through the sealing piece 9. The pressurized air flow will flow out through the multiple groups of grooves 15 on the outer wall of the pressure plate 11 and the multiple groups of exhaust ports 17 on the second nut 7 in the second nut 7, and then the fire extinguishing material in the storage bottle will be discharged through the control valve body 1 and the nozzle 3. The screw 10 will flip and drive the pressure plate 11 and the fixed block 12 to move downward and fit with the sealing piece 9, thereby completing the sealing inside the control valve body 1. The above is the entire working principle of the present utility model.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
