Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a high-intensity direct-injection carbon dioxide valve. Background Art

[0002] Fire extinguishers are portable firefighting devices used to extinguish initial fires. They typically consist of a pressure tank and a nozzle. Fire extinguishers are common firefighting equipment and are stored in public places or areas where fires may occur. Different types of fire extinguishers contain different ingredients and are designed for different fire causes. Care must be taken when using them to avoid adverse effects and dangers. They contain extinguishing agents that can be quickly released when a fire occurs, spraying directly at the fire source to extinguish the flames.

[0003] When carbon dioxide gas accumulates inside the valve, it may cause the system pressure to be too high. If the gas cannot be released in time, it may accumulate, affecting the normal operation and reliability of the system. At the same time, it limits the ability to respond quickly in an emergency, which increases the safety risk of equipment and poses a threat to the safety of operators. At the same time, the internal pressure of the system cannot be balanced, causing gas accumulation, thereby increasing the risk of equipment being pressurized and even causing damage to the valve or other components, resulting in unsatisfactory injection effect, which in turn affects the fire extinguishing effect. Utility Model Content

[0025] 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.

[0026] See also Figure 1-6 The utility model provides a technical solution: a high-strength direct-injection carbon dioxide valve, comprising: a valve body 1, a valve stem 2, a mouth ring 3, a connector 4, a sealing gasket 5, a valve stem cap 6, a gasket 7, a first spring 8, a riser seat 9, a rivet 10, a lifting and pressure handle 11, a safety pin 12, a rubber chain 13, an air core 14, an inflatable screw cover 15, a sealing flat gasket 16, a first sealing head 17, a pull rod 18, a sealing baffle 19, a second spring 201, an exhaust pipe 21, a sealing ring 22, a return pipe 23, a second sealing head 24, a threaded rod 25, and a stop plate 26.

[0027] First, as attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 and attached Figure 6 As shown in , when using the modified device, first install the device on the fire extinguisher, and then make the connecting head 4 sleeve fixedly installed on the fire extinguisher, so that the standpipe seat 9 is inserted into the interior of the equipment. At the same time, when using the device, first pull out the safety pin 12 and the rivet 10, so that the safety pin 12 and the rivet 10 release the fixation between the pressure-lifting handle 11 and the valve body 1, and then make the pulled-out safety pin 12 hang on the pressure-lifting handle 11 through the rubber chain 13. At the same time, the inflation screw cap 15 and the left end of the valve body 1 can also be unscrewed according to actual usage. Since the sealing flat gasket 16 is fixedly installed inside the inflation screw cap 15, and the sealing flat gasket 16 is attached to the side wall of the valve body 1 to form a sealed state, the valve body 1 is released from the seal by unscrewing the inflation screw cap 15, and then the external inflation device and the gas inside the valve body 1 can be connected according to usage. The core 14 is connected, and then the interior of the device is inflated through the valve body 1. When the gas is filled, the inflation screw cap 15 is screwed on to seal the valve body 1 again. When the gas is filled, the pressure lifting handle 11 can be pressed, and the pressure lifting handle 11 drives the valve stem 2 to slide inside the valve body 1. At the same time, a sealed state is formed between the sealing gasket 5, the valve stem cap 6 and the gasket 7 to form a sealed state inside the valve body 1, so that the valve stem 2 releases the seal of the valve body 1 through the sealing gasket 5, the valve stem cap 6 and the gasket 7, and at the same time, the valve stem cap 6 drives the first spring 8 to compress, so that the internal liquid of the device is ejected through the left end of the valve body 1 by the air pressure inside the device, and the valve body 1 is sealed by the mouth ring 3 on the top of the valve body 1. When the injection is completed, the valve stem 2 is reset by the elastic force of the first spring 8, and the valve body 1 is sealed again;

[0028] As attached Figure 1 and attached Figure 3As shown in, when the device is used in conjunction with a fire extinguisher, it may be because it has not been used for a long time or the air pressure inside the device is too high, and then the pull rods 18 at the left and right ends of the top of the connector 4 can be pulled. Since the sealing baffle 19 is arranged in a fit state with the inner side wall of the connector 4, the pull rod 18 drives the sealing baffle 19 to slide inside the connector 4. At the same time, the sealing baffle 19 and the connector 4 cooperate with each other to seal the device and the fire extinguisher, and a sealing ring 22 is fixedly installed on the inner top of the connector 4 to seal it. Then, the exhaust pipe 21 is connected to the connector 4 in an "L"-shaped structure, so that the pull rod 18 drives the sealing baffle 19 to slide to the inside of the first sealing head 17, and then the sealing baffle 19 drives the second spring 20 to compress. When the sealing baffle 19 is placed inside the first sealing head 17, the exhaust pipe 21 is connected to the connector 4 and the fire extinguisher, thereby discharging excess gas in the fire extinguisher to prevent the risk of explosion or equipment damage caused by overpressure of the system;

[0029] As attached Figure 1 and attached Figure 4 As shown in, when the device and the fire extinguisher are closed and in operation, the threaded rod 25 can be rotated. Since the threaded rod 25 is connected to the inner wall of the second sealing head 24 by threads, and the left end rod body of the threaded rod 25 is rotatably connected together with the stop plate 26, and then the return pipe 23 is arranged in a "U"-shaped structure, and the stop plate 26 is arranged in a fit state with the return pipe 23, and the stop plate 26 is also arranged in a fit state with the inner wall of the second sealing head 24, and then the stop plate 26 is driven to slide inside the return pipe 23 and the stop plate 26 by rotating the threaded rod 25, and at the same time, the return pipe 23 is connected to the valve body 1 and the connector 4. When the device has excess gas pressure and liquid, the excess gas or liquid is refluxed through the connection between the return pipe 23, the valve body 1 and the connector 4.
