Description

Technical Field

[0001] This utility model relates to fire extinguishing devices, specifically to a fire extinguisher valve body. Background Technology

[0002] Fire extinguishers have important applications in the field of fire protection. A fire extinguisher consists of a cylinder, a valve body connected to the cylinder, and a pressure handle connected to the valve body. When using a fire extinguisher to put out a fire, especially a large fire with high temperature, the user holds the fire extinguisher a distance from the fire to avoid being burned, which affects the extinguishing effect. At the same time, if the pressure gauge of a fire extinguisher is damaged, the entire extinguisher must be discarded, which is a waste of resources.

[0003] Therefore, there is an urgent need for a new type of fire extinguisher valve body that not only has the fire extinguishing effect of traditional fire extinguishers, but also increases the spray distance of the fire extinguishing agent, enabling long-distance fire suppression and ensuring fire extinguishing effectiveness; at the same time, if the pressure gauge is damaged, it can be quickly and independently replaced and maintained, reducing resource waste and extending the service life of the fire extinguisher. Utility Model Content

[0004] This utility model provides a fire extinguisher valve body. Fire extinguishers using this valve body not only have the fire extinguishing effect of traditional fire extinguishers, but also increase the spray distance of the fire extinguishing agent, enabling fire extinguishing from a distance and ensuring the fire extinguishing effect.

[0005] The present invention adopts the following technical solution:

[0006] A fire extinguisher valve body includes a valve body main body connected to a cylinder and a pressure handle connected to the valve body main body. The valve body main body includes a nozzle and a pressure port located on the side wall. An extension mechanism is snapped onto the nozzle, and a valve core is provided in the pressure port. The pressure port is used to connect to an external pressure gauge to monitor the pressure status inside the fire extinguisher. The extension mechanism includes a connecting pipe snapped onto the nozzle, a sliding rail with a square frame structure fixedly connected to the connecting pipe, a movable plate slidably disposed in the sliding rail, an extension pipe with a tubular structure that passes through the movable plate and is adapted to the connecting pipe, an axial flow fan fixedly disposed in the extension pipe, a mounting block fixedly disposed on the outer side wall of the extension pipe, a battery module fixedly disposed on the mounting block for providing power to the axial flow fan, and a switch module disposed on the mounting block for controlling the switching of the axial flow fan.

[0007] Furthermore, to improve the installation effect, the connecting pipe is sleeved outside the nozzle, and the connecting pipe and the nozzle are fixedly connected by several bolts; the axial flow fan is a servo axial flow fan, and there are 3 bolts distributed symmetrically.

[0008] Preferably, to improve ease of use, the switch module is a reset switch module and the battery module is a rechargeable lithium battery module.

[0009] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. This utility model has a sliding range extender tube on the nozzle, and an axial flow fan is installed inside the range extender tube. When the user needs to increase the spray distance of the extinguishing agent, the sliding range extender tube is connected to the nozzle to increase the spray distance of the extinguishing agent and meet the user's long-distance fire extinguishing effect; 2. This utility model has a valve core inside the pressure port. When the pressure gauge is damaged, the user can remove the damaged pressure gauge and seal the internal pressure leakage through the valve core. When a new pressure gauge is installed, the valve core is pushed open, and the pressure gauge is connected to the internal gas to monitor the internal pressure. This avoids the situation where the entire fire extinguisher cannot be used due to the damage of a single pressure gauge, and reduces the waste of resources. Attached Figure Description

Detailed Implementation

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] See Figures 1 to 5A fire extinguisher valve body includes a valve body 1 connected to a cylinder and a pressure handle 2 connected to the valve body 1. The valve body 1 includes a nozzle 11 and a pressure port 12 located on the side wall. A range extender 3 is snapped onto the nozzle 11. A valve core is provided in the pressure port 12. The pressure port 12 is used to connect to an external pressure gauge to monitor the pressure status inside the fire extinguisher. The range extender 3 includes a connecting pipe 31 snapped onto the nozzle 11, a sliding rail 32 with a square frame structure fixedly connected to the connecting pipe 31, a movable plate 33 slidably disposed in the sliding rail 32, and a through-hole opened in the movable plate 33. The system includes a tubular extension pipe 34 adapted to the connecting pipe 31, an axial flow fan 35 fixed inside the extension pipe 34, a mounting block 36 fixed on the outer wall of the extension pipe 34, a battery module 37 fixed on the mounting block 36 for providing power to the axial flow fan 35, and a switch module 38 fixed on the mounting block 36 for controlling the switching of the axial flow fan 35. When the pressure gauge is damaged, the user removes the damaged pressure gauge and seals the internal pressure leakage through the valve core. When a new pressure gauge is installed, the valve core is opened, allowing the pressure gauge to communicate with the internal gas and monitor the internal pressure.

[0018] See Figures 1 to 5 To improve installation efficiency, the connecting pipe 31 is fitted onto the outside of the nozzle 11, and the connecting pipe 31 and the nozzle 11 are fixedly connected by several bolts 311; the axial flow fan 35 is a servo axial flow fan, and there are three bolts 311 distributed symmetrically. To improve ease of use, the switch module 38 is a reset switch module, and the battery module 37 is a rechargeable lithium battery module.

[0019] Working principle: This utility model has a range extender pipe 34 with an axial flow fan 35 that is slidably installed on the nozzle 11. When encountering a high-temperature fire and the user cannot extinguish the fire at close range, the range extender pipe 34 is slid onto the nozzle 11, so that the extinguishing agent can be sprayed at the fire point from a distance, ensuring the fire extinguishing effect.

[0020] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
