Technical Field

[0001] This utility model relates to the field of fire extinguisher bottle valve technology, specifically a fire extinguisher bottle valve body. Background Technology

[0002] A fire extinguisher cylinder valve is a valve on a fire extinguisher used to control the release of the extinguishing agent. This valve is located on the fire extinguisher cylinder and usually has a handle or button. When the user needs to use the fire extinguisher, they operate this valve to release the extinguishing agent stored in the cylinder.

[0003] Although the fire extinguisher cylinder valve assembly is a key component of the fire extinguishing system, its installation is often subject to various limitations. Due to the complexity of its valve body and installation piping, as well as the numerous components, adjusting the equipment's orientation can be difficult. Furthermore, subsequent maintenance requires the complete disassembly and depressurization of the fire extinguisher cylinder valve body, a process that is not only cumbersome and time-consuming but also poses significant safety risks.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a fire extinguisher bottle valve body. Utility Model Content

[0005] The purpose of this invention is to provide a fire extinguisher bottle valve body to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A technical solution for a fire extinguisher bottle valve body includes a valve body body, a valve body cap on the upper part of the valve body body, an exhaust ball valve on the outer wall of the valve body cap, an emergency button installed on the valve body cap on the opposite side of the exhaust ball valve, an anti-leakage component between the exhaust ball valve and the emergency button, a chemical release end at the bottom of the valve body body, a chemical release sensor on the chemical release end, a safety pressure relief valve on the lower outer wall of the valve body body, a valve body mounting end at the bottom of the valve body body, and a small anti-blockage device at the lower part of the valve body body.

[0008] As a preferred technical solution, the anti-leakage assembly includes an anti-leakage plug, a pressure plate nut, and a diaphragm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model relates to a fire extinguisher bottle valve body. By providing an emergency button mounting hole on the top of the valve body, it solves the problem of difficult or incomplete installation of the emergency button due to space limitations. Furthermore, the introduction of a chemical release sensor allows for real-time monitoring of whether the fire extinguishing device successfully activates during a fire, facilitating subsequent control and operation by personnel.

Detailed Implementation

[0022] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0023] like Figure 1-6 As shown, this utility model provides a technical solution for a fire extinguisher bottle valve body: it includes a valve body body 1, a valve body cap 2 on the upper part of the valve body body 1, an exhaust ball valve 3 on the outer wall of the valve body cap 2, an emergency button 5 installed on the valve body cap 2 opposite to the exhaust ball valve 3, and an anti-leakage component 4 between the exhaust ball valve 3 and the emergency button 5. The anti-leakage component 4 includes an anti-leakage plug 401, a pressure nut 402, and a diaphragm. The anti-leakage plug 401 is installed inside the valve body cap 2, the pressure nut 402 is installed inside the anti-leakage plug 401, and a diaphragm is installed inside the pressure nut 402.

[0024] The valve body cap 2 is provided with a ball valve mounting hole 14 and an emergency button mounting hole 15. The ball valve mounting hole 14 is used to install the exhaust ball valve 3, and the emergency button mounting hole 15 is used to install the emergency button 5.

[0025] The drug release end 6 is provided with a drug release sensor mounting hole 16, which is used for installing the drug release sensor 7.

[0026] The valve body 1 has a vent 17 at the bottom and a vent channel 13 inside the vent 17. The vent 17 is used to install a protective small blockage 8.

[0027] Among them, the lower part of the valve body 1 is provided with an inflation switch 11 and an inflation switch 2 12.

[0028] In this embodiment, the installation of fire extinguishing devices (especially those involving vehicles) is often limited due to the large size of the agent bottle valve assembly (particularly the bottle head valve, which has limited options for installation direction due to its numerous connecting pipes and fittings). This is addressed by improving the valve body cap.

[0029] This design allows for more flexible installation of the fire extinguisher cylinder valve body, improving installation efficiency. Furthermore, the improved design of the valve cap 2 allows for a more rational layout of the exhaust ball valve 3 and the emergency button 5, ensuring rapid and effective operation in emergencies.

[0030] Furthermore, the agent release sensor 7 enables the fire extinguisher to monitor the agent release in real time upon activation, ensuring that the extinguishing agent is accurately sprayed onto the fire source. This feature is of great significance for improving fire extinguishing efficiency and ensuring fire extinguishing effectiveness.

[0031] The safety relief valve has a dual function: First, if improper operation leads to excessive pressure during the pressurization process of the container, the relief valve can release the excess pressure in time.

[0032] Secondly, under specific conditions, temperature increases may cause pressure increases due to climate fluctuations or geographical differences. When the pressure exceeds the safety threshold, the safety relief valve can automatically activate to ensure that the pressure inside the container is maintained within a stable range of 1.5 to 1.6 MPa.

[0033] The main function of the small blockage protection is to release the pressure inside the bottle during later maintenance, such as when changing medications. This is achieved by opening the small blockage and using the venting channel 13. This allows the medication bottle valve to open smoothly without inverting or depressurizing, saving time and labor. (Typically, the medication bottle contains approximately 1.5 MPa of pressure. The gas pressure is concentrated at the top of the bottle; opening it directly without prior venting could pose a serious safety hazard.)

[0034] The inclusion of inflation switch 11 and inflation switch 212 makes the inflation process of the fire extinguisher cylinder more convenient and safer. During inflation, the operator can select the appropriate switch as needed to ensure that the fire extinguisher cylinder reaches the specified pressure standard.

[0035] The working principle and usage process of this utility model are as follows: When in operation, the fire extinguishing agent is first filled into the bottle through the inflation switch 11 or the inflation switch 12. At the same time, the safety pressure relief valve ensures that the pressure inside the bottle does not exceed the set value to prevent safety problems caused by excessive pressure.

[0036] When the fire extinguisher needs to be used, the operator presses the emergency button 5. At this time, the exhaust ball valve 3 opens, and the agent is quickly released through the venting channel 13. The agent release sensor 7 monitors the release of the agent in real time to ensure that the agent can be accurately sprayed to the fire source.

[0037] During firefighting, if the pressure inside the cylinder rises abnormally, the safety relief valve will automatically open to release the excess pressure and keep the pressure inside the cylinder within a safe range, thereby avoiding the risk of explosion due to excessive pressure.

[0038] After the fire is extinguished, if it is necessary to replace the agent or perform maintenance, the protective plug 8 can be opened to release the pressure inside the cylinder through the venting channel 13. Then the cylinder valve can be opened normally for maintenance operations. There is no need to invert the cylinder or perform complicated pressure release operations, which greatly improves maintenance efficiency.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
