DETAILED DESCRIPTION

[0028] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention provides a technical solution of a piston-free valve body for fire extinguishing equipment: comprising a fire extinguishing agent bottle 1, which is the core part of the entire device and is used to store fire extinguishing agent. A valve body 2 is installed on the top of the fire extinguishing agent bottle 1, and a valve body fixing end 24 is designed on the bottom surface of the valve body 2. The valve body fixing end 24 is closely connected to the fire extinguishing agent bottle 1, ensuring the stability and sealing of the valve body 2. On the valve body fixing end 24, a gas release channel 241 is provided, which is used to release the pressure in the bottle when necessary to ensure safe use.

[0030] The front end of the valve body 2 is designed with a charging port 21, through which the required gas can be charged into the fire extinguishing agent bottle 1 to maintain the pressure in the bottle. The rear end of the valve body 2 is provided with a reagent outlet 22, through which the fire extinguishing agent is released to achieve the purpose of extinguishing the fire. At the top of the valve body 2, a puncture starter installation port 27 is also designed for installing the puncture starter 4, so as to quickly start the release of the fire extinguishing agent in an emergency.

[0031] An opening 271 is provided in the puncture actuator installation port 27, and a pressure plate nut installation port 272 is provided below the opening 271. A diaphragm placement cavity 273 is designed in the pressure plate nut installation port 272 for placing the diaphragm 42. A channel 1 274 is provided below the diaphragm placement cavity 273, and the channel 1 274 is connected to the pressure gauge 3, so that the operator can monitor the pressure in the bottle in real time.

[0032] A pressure piece nut 41 is connected to the bottom of the piercing actuator 4, and the pressure piece nut 41 is installed in the pressure piece nut installation port 272 to ensure the stability and reliability of the piercing actuator 4. A diaphragm 42 is installed in the diaphragm placement cavity 273, and the diaphragm 42 can be pierced under the action of the piercing actuator 4, thereby starting the release process of the fire extinguishing agent.

[0033] Furthermore, the left side of the valve body 2 is provided with a safety relief valve installation port 25 and a pressure sensor installation port 26. The safety relief valve installation port 25 is directly connected to the safety relief valve 5 to ensure that the pressure can be quickly released when the system pressure is too high, thereby ensuring the safe operation of the entire system. The pressure sensor installation port 26 is connected to the pressure sensor 6 to monitor the pressure changes in the system in real time and ensure that the system operates in the best working state.

[0034] Furthermore, the agent outlet 22 is connected to the opening 271, ensuring that the agent can smoothly flow from the outlet 22 to the opening 271, thereby achieving its intended function. At the same time, there is also close connectivity between the diaphragm placement cavity 273 and the valve body fixed end 24 and the fire extinguishing agent bottle 1. This connectivity enables the diaphragm placement cavity 273 to form a complete system with the valve body fixed end 24 and the fire extinguishing agent bottle 1, ensuring that the fire extinguishing agent can be quickly and effectively released from the fire extinguishing agent bottle 1 when needed, and finally achieve the purpose of extinguishing the fire through the passage of the valve body fixed end 24 and the diaphragm placement cavity 273.

[0035] Furthermore, an inspection port 28 is provided on the valve body 2 on the adjacent side of the pressure gauge 3. The inspection port 28 is for the convenience of maintenance and overhaul during the operation of the equipment. An inspection plug 23 is installed inside the inspection port 28, and the function of the inspection plug 23 is to close the inspection port 28 during normal operation to prevent leakage of the medium or other unexpected situations. When inspection or maintenance is required, the inspection plug 23 can be removed to open the inspection port 28 so that the staff can enter and perform necessary operations. Such a design not only ensures the safe operation of the equipment, but also greatly improves the convenience and efficiency of maintenance.

[0036] Furthermore, a pressure gauge installation port 29 is designed on the right side of the valve body 2. The pressure gauge 3 is installed in the pressure gauge installation port 29, and a mesh pad 32 is provided at the end of the pressure gauge 3. The function of this mesh pad 32 is to protect the pressure gauge 3 and prevent foreign matter from entering the interior of the pressure gauge during the measurement process, thereby affecting its measurement accuracy and service life. In addition, a mesh pad nut 31 is connected to the pressure gauge 3. The function of this mesh pad nut 31 is to fix the pressure gauge 3 to prevent it from loosening or falling off during use. The mesh pad nut 31 is located in the pressure gauge installation port 29 and fits tightly with the pressure gauge 3 to ensure the stability and accuracy of the entire measurement system.

[0037] Specifically, the inspection port 28 is built with a channel and is connected to the deflation channel 241. The charging port 21, the agent outlet 22, the safety pressure relief valve installation port 25, the pressure sensor installation port 26, the pressure gauge installation port 29, and the puncture starter installation port 27 are all built with channels and connected to the valve body fixed end 25, so that the fire extinguishing equipment can be in a standby state. The fire extinguishing agent bottle 1 is filled with an appropriate amount of fire extinguishing agent and the required pressure is maintained through the charging port 21. The pressure gauge 3 monitors the pressure in the bottle in real time to ensure safety. In an emergency, the puncture starter 4 is installed and started, the diaphragm 42 is punctured, and the fire extinguishing agent is quickly released. The safety pressure relief valve 5 and the pressure sensor 6 automatically release pressure and monitor the pressure in real time when the pressure is too high. After the fire extinguishing agent is released, the inspection port 28 is convenient for inspection and maintenance, and the pressure gauge 3 can be calibrated or replaced. The piston-free valve body design improves the reliability and service life of the equipment, reduces the maintenance cost, is easy to carry and store, has strong adaptability, and ensures the normal startup and operation of the fire extinguishing equipment.

[0038] In this embodiment, the fire extinguishing device is ensured to be in a standby state, an appropriate amount of fire extinguishing agent has been filled into the fire extinguishing agent bottle 1, and the required gas is filled into the bottle through the filling port 21 to maintain the pressure. Under normal circumstances, the pressure in the fire extinguishing agent bottle 1 is monitored in real time by the pressure gauge 3 to ensure that it is within a safe range.

[0039] When an emergency such as a fire occurs, the operator can quickly install the puncture actuator 4 on the puncture actuator installation port 27 and fix it with the press nut 41. Under the action of the puncture actuator 4, the diaphragm 42 is punctured, so that the fire extinguishing agent is quickly released through the agent outlet 22 to achieve the purpose of fire extinguishing.

[0040] During the release of the fire extinguishing agent, the safety pressure relief valve 5 can ensure that the system automatically releases pressure when the pressure is too high to avoid equipment damage caused by excessive pressure. At the same time, the pressure sensor 6 can monitor the pressure in the bottle in real time and transmit the data to the control system for further analysis and processing.

[0041] After the extinguishing agent is released, the operator can perform inspection and maintenance through the inspection port 28. An inspection plug 23 is installed in the inspection port 28 to facilitate plugging when necessary. In addition, the mesh nut 31 of the pressure gauge 3 can be easily removed so that the pressure gauge can be calibrated or replaced.

[0042] The piston-free valve body design of the entire fire extinguishing equipment not only improves the reliability and service life of the equipment, but also reduces the maintenance cost and frequency. Its compact structure design makes the equipment easier to carry and store, and it has strong adaptability and can ensure normal startup and operation in various environments, providing a strong guarantee for fire extinguishing work.
