[0023] refer to Figure 1-4 , an intelligent pressure monitoring valve, including a valve body 1, the valve body 1 is installed on the fire extinguishing agent bottle, is the main structure of the entire valve, and provides installation space and support for each internal component. A valve cavity 2 is arranged in the valve body 1, and the valve cavity 2 can provide space for the movement of a valve core component 3 and the circulation of the fire extinguishing agent. A slidable valve core component 3 is arranged in the valve cavity 2. The circulation of the fire extinguishing agent can be controlled by sliding the valve core component 3 in the valve cavity 2, thereby controlling the opening and closing of the valve. A valve cover component 4 is arranged on the top of the valve body 1 and sealed on the top of the valve cavity 2, which plays a role in protecting the internal components and sealing. A connector 5 is arranged on the top of the valve cover component 4, which can be used to connect an external device (such as an electromagnetic drive device, etc.) to open the valve when needed. The valve allows the fire extinguishing agent in the fire extinguishing agent bottle to flow out, thereby realizing the fire extinguishing function of the fire extinguishing agent bottle. The pressure monitoring component 6 is embedded in the valve body 1, and can monitor the pressure in the valve cavity 2. The pressure monitoring component 6 is completely sealed in the valve body 1, and is less affected by the external environment, thereby avoiding the problem that the pressure monitoring component 6 is easily damaged in harsh environments such as low temperature, high humidity, and strong vibration. The pressure monitoring component 6 can maintain stable monitoring performance under various working conditions, and is not prone to equipment failure due to rust or false alarm of pressure leakage due to poor sealing. At the same time, it can reduce connection points and pipelines, improve the reliability of the system, and can read the real-time pressure value in the fire extinguishing agent bottle without manual operation, thereby improving the timeliness and accuracy of monitoring.

[0024] In some embodiments, the valve body 1 includes a fire extinguishing agent inlet 11 and a fire extinguishing agent outlet 12. The fire extinguishing agent inlet 11 is arranged at the bottom of the valve body 1 and is the entrance for the fire extinguishing agent to enter the valve.

The fire extinguishing agent outlet 12 is arranged on the side of the valve body 1 and is connected to the fire extinguishing nozzle and the valve cavity 2. The fire extinguishing agent in the valve cavity 2 can be transported to the fire extinguishing nozzle for fire extinguishing operations. A pressure monitoring component 6 is provided between the fire extinguishing agent inlet 11 and the fire extinguishing agent outlet 12, which can accurately monitor the pressure in the valve cavity 2 when the fire extinguishing agent is flowing, thereby improving the accuracy of the monitoring value of the pressure monitoring component 6.

[0025] In some embodiments, the valve core assembly 3 includes a valve core body 31, a pressure cover 32, a first sealing ring 33, a connecting hole 34, and a second sealing ring 35. The valve core body 31 can be slidably arranged in the valve cavity 2 to control the circulation of the fire extinguishing agent. The pressure cover 32 is arranged at the bottom of the valve core body 31 to fix and protect the first sealing ring 33. The first sealing ring 33 is arranged between the valve core body 31 and the pressure cover 32 to prevent leakage of the fire extinguishing agent. The connecting hole 34 runs through the valve core body 31 and the pressure cover 32, thereby realizing the connection between the upper and lower chambers of the valve core assembly 3, so that the airflow can flow through the connecting hole 34, so that the pressure of the upper and lower chambers is balanced. The second sealing ring 35 is coaxially sleeved on the top of the valve core body 31, and is slidably and sealingly connected to the inner wall of the valve cavity 2, which can ensure the sealing of the valve cavity 2 during the sliding process of the valve core body 31.

[0026] In some embodiments, the valve cover assembly 4 includes a cover body 41, a mounting groove, an exhaust hole 42, a first diaphragm 43, and a sealing member 44. The top of the cover body 41 is detachably connected to the connector 5 to facilitate later disassembly and maintenance. The mounting groove is provided at the bottom of the cover body 41 and is detachably connected to the top of the valve body 1, so that the valve cover assembly 4 and the valve body 1 can be installed and fixed. The exhaust hole 42 runs through the cover body 41 and is connected to the valve cavity 2, so that the gas in the valve cavity 2 can be discharged and the pressure distribution in the valve cavity 2 can be changed, so that the valve core assembly 3 can slide in the valve cavity 2, thereby realizing the control of the flow of the fire extinguishing agent; the first diaphragm 43 is sealed at the top of the exhaust hole 42 to seal the valve cavity 2. The sealing member 44 is provided between the valve body 1 and the mounting groove to enhance the sealing of the connection between the valve body 1 and the mounting groove.

[0027] In some embodiments, the sealing member 44 includes a first annular groove, a third sealing ring 441, a second annular groove, a third annular groove, and a sealing gasket 442. The first annular groove is provided on the inner bottom wall of the mounting groove, the third sealing ring 441 is provided in the first annular groove, the second annular groove is provided at the connection between the bottom wall and the side wall of the mounting groove, the third annular groove is provided on the outer side wall of the bottom of the valve body 1, and the sealing gasket 442 is provided between the second annular groove and the third annular groove. The third sealing ring 441 can enhance the sealing of the bottom of the mounting groove, the sealing gasket 442 can enhance the sealing of the connection between the valve body 1 and the valve cover assembly 4, and the double sealing structure can ensure the sealing performance of the connection between the valve body 1 and the valve cover assembly 4 to prevent leakage of the fire extinguishing agent.

[0028] In some embodiments, reference Figure 4The pressure monitoring assembly 6 includes a fixed groove, a pressure sensor 61, and a pressure display 62. The fixed groove runs through a side wall of the valve body 1 and is arranged between the fire extinguishing agent inlet 11 and the fire extinguishing agent outlet 12, which can provide an installation position for the pressure sensor 61 and the pressure display 62. The pressure sensor 61 is arranged in the fixed groove, and the measuring end of the pressure sensor 61 extends into the valve cavity 2, which can monitor the pressure in the valve cavity 2 in real time, reduce the pressure loss of the external measuring device, and thus improve the measurement accuracy. The pressure display 62 is connected to the pressure sensor 61, and the pressure display 62 is arranged on the side of the fixed groove away from the valve cavity 2. The pressure display 62 can be a liquid crystal display screen, which can display the pressure data monitored by the pressure sensor 61, which is convenient for the staff to view, and the side of the pressure display 62 away from the pressure sensor 61 is flush with an end face of the fixed groove, so as to avoid damage caused by the pressure display 62 protruding from the side wall of the valve body 1. The pressure sensor 61 monitors the pressure in the valve cavity 2 in real time. When the pressure changes, the pressure sensor 61 transmits the pressure signal to the pressure display element 62, and the pressure display element 62 displays the pressure data intuitively.

[0029] The pressure sensor 61 can be a high-precision pressure sensor with wireless data transmission. The pressure sensor 61 can be connected to the intelligent alarm system and the Internet of Things linkage system by radio, and can transmit the real-time pressure signal to the intelligent alarm system and the Internet of Things linkage system, which can reduce the pressure of personnel inspections, and can remotely view the real-time pressure status of each monitoring point, discover abnormalities in time and take measures, thereby improving work efficiency, reducing labor costs, and providing reliable data support for the maintenance party to achieve refined management, thereby ensuring the safe and stable operation of the system.

[0030] Specifically, when the pressure is lower than the preset range, the intelligent alarm system triggers the alarm mechanism and notifies relevant personnel. When the fire extinguisher bottle is disassembled or sprayed, the intelligent alarm system will record the abnormal pressure value to prevent users from disassembling or modifying it privately, and can upload these abnormal events and specific time, pressure change data and other information to the cloud platform in real time to form a complete equipment use record. This not only helps to trace responsibility, but also provides detailed data basis for subsequent equipment maintenance and management.

[0031] When the IoT pressure monitoring valve generates an alarm signal, the alarm information can be transmitted to the cloud platform in a timely manner using LoRa / 4G and other methods. After the cloud platform receives the abnormal pressure, it notifies the maintenance party in real time through SMS, phone, and WeChat push. Compared with traditional wired pressure monitoring, it reduces the difficulty of installation and makes equipment maintenance more intelligent and precise. The system can analyze the pressure change trend based on historical data, warn of possible failures in advance, and realize predictive maintenance. This can not only improve the reliability of equipment operation, but also reduce the cost of manual inspections, and provide strong support for the intelligent transformation of fire protection facilities.

[0032] In some embodiments, the pressure monitoring component 6 also includes a stabilizing layer 63, which is arranged between the inner wall of the fixing groove and the pressure sensor 61 and the pressure display component 62, so as to realize the stable installation of the pressure sensor 61 and the pressure display component 62 in the installation groove and prevent them from displacement or damage during the operation of the valve. The stabilizing layer 63 can be formed by filling and solidifying epoxy resin, so as to realize the sealed installation of the pressure monitoring component 6 on the valve body 1. At the same time, through the elastic properties of the epoxy resin, the vibration capacity generated when the valve is working can be absorbed, thereby eliminating vibration interference, improving the measurement accuracy of the pressure monitoring component 6, and protecting the pressure sensor 61 and the pressure display component 62, thereby reducing the failure rate of the pressure monitoring component 6. At the same time, no additional steps are required, and the installation of the equipment can be completed by only installing the valve during the production process, thereby reducing potential leakage points and reducing potential hidden dangers of poor installation due to operating level.

[0033] In some embodiments, the fixed groove includes a plug-in portion, a first filling portion, and a second filling portion. The plug-in portion is arranged on the side of the fixed groove close to the valve cavity 2, and is plugged into and matched with the pressure sensor 61, so as to realize the preliminary fixation of the pressure sensor 61 and facilitate the installation of the pressure sensor 61. The first filling portion is coaxially connected to the plug-in portion, and the pressure sensor 61 is coaxially arranged thereon. The second filling portion is coaxially connected to the first filling portion, and a pressure display component 62 is coaxially arranged thereon. A stabilizing layer 63 is provided between the first filling portion and the second filling portion. The pressure sensor 61 and the pressure display component 62 can be installed in the fixed groove through the stabilizing layer 63, so as to realize the embedded installation of the pressure monitoring assembly 6 on the valve body 1, thereby avoiding the problems of rust, poor sealing, etc. caused by the external measuring device.

[0034] In some embodiments, a reduction component 7 is also included. The reduction component 7 is arranged between the valve core component 3 and the valve cover component 4. The reduction component 7 includes a reduction groove 71 and a reduction spring 72. The reduction groove 71 is arranged at the top of the valve core component 3. The bottom of the reduction spring 72 is fixed in the reduction groove 71, which can constrain the contraction direction of the reduction spring 72 to ensure the stability of the deformation process of the reduction spring 72. The top of the reduction spring 72 is fixed at the bottom of the valve cover component 4. Through the elastic action of the reduction spring 72, the movement of the valve core component 3 in the valve cavity 2 can be buffered and adjusted, so as to avoid the valve core component 3 directly hitting the valve cover component 4 under the impact force of the fire extinguishing agent when the fire extinguishing agent is sprayed, so as to damage the valve core component 3 and the valve cover component 4, thereby affecting the sealing performance of the valve and causing leakage of the fire extinguishing agent.

[0035] Specifically, when the fire extinguishing agent enters the valve cavity 2, the pressure pushes the valve core body 31 to slide upward in the valve cavity 2. The drop spring 72 at the top of the valve core assembly 3 is compressed, which plays a buffering role to prevent the valve core assembly 3 from moving quickly and causing damage to the valve. When the fire extinguishing agent stops entering or the pressure decreases, the elastic force of the drop spring 72 pushes the valve core body 31 to slide downward to control the flow of the fire extinguishing agent. The valve cover assembly 4 plays a sealing and protective role to ensure that the valve core assembly 3 works normally in the valve cavity 2.

[0036] In some embodiments, a safety component 8 is also included. The safety component 8 includes a safety groove, a second diaphragm 81, a safety plug 82, and an air bleed hole 83. The safety groove is arranged on the side wall of the valve body 1 and is connected to the valve cavity 2. The second diaphragm 81 is sealed in the safety groove to isolate the valve cavity 2 from the external environment. The safety plug 82 is threadedly matched with the safety groove to facilitate the installation and removal of the safety plug 82. At the same time, it is convenient to rotate the safety plug 82 so that the safety plug 82 pierces the second diaphragm 81 at different positions, thereby realizing the adjustment of the valve warning pressure. The air bleed hole 83 runs through the safety plug 82. When the internal pressure of the valve is abnormal, the safety plug 82 pierces the second diaphragm 81 and discharges the gas in the valve cavity 2 through the air bleed hole 83 to relieve the pressure and ensure the safety of the valve.

[0037] Specifically, when the pressure in the valve chamber 2 rises abnormally, the pressure acts on the second diaphragm 81, causing the second diaphragm 81 to suddenly change in the direction of the safety screw plug 82. When the pressure exceeds a certain value, the second diaphragm 81 is punctured by the safety screw plug 82, and the gas in the valve chamber 2 is depressurized through the safety groove and the air vent 83, preventing the valve from being damaged due to excessive pressure, thereby ensuring the safety of the valve and the entire gas fire extinguishing system.

[0038] In some embodiments, a blowout prevention assembly 9 is also included, and the blowout prevention assembly 9 includes a blowout prevention cover 91. The blowout prevention cover 91 is covered on the fire extinguishing agent outlet 12 and is screwed with the outer wall of the fire extinguishing agent outlet 12 to block the fire extinguishing agent outlet 12 to avoid accidental spraying of the fire extinguishing agent and protect the valve. A chain 92 is hinged on the blowout prevention cover 91, and a fixing pin 93 is hinged on the other end of the chain 92. The fixing pin 93 is fixed on the valve body 1. Through the cooperation of the fixing pin 93 and the chain 92, the blowout prevention cover 91 can be separated from the fire extinguishing agent outlet 12 and still connected to the valve body 1 to avoid the loss of the blowout prevention cover 91.

[0039] The specific working principle is as follows: In normal state, the valve core body 31 in the valve core assembly 3 remains relatively still in the valve cavity 2, and the pressure cap 32 and the first sealing ring 33 at the bottom of the valve core body 31 are tightly matched to prevent the fire extinguishing agent from leaking from the bottom of the valve core assembly 3. The second sealing ring 35 is coaxially sleeved on the top of the valve core body 31, sliding and sealingly connected with the inner wall of the valve cavity 2, ensuring the overall sealing of the valve cavity 2, thereby maintaining the pressure in the fire extinguishing agent bottle stable and preventing the fire extinguishing agent from leaking. At this time, the cover body 41 of the valve cover assembly 4 is detachably connected to the top of the valve body 1 through the installation groove, and the third sealing ring 441 and the sealing gasket 442 in the sealing member 44 play a double sealing role, further ensuring the sealing of the connection between the valve body 1 and the valve cover assembly 4, preventing external impurities from entering the valve cavity 2, and also avoiding the leakage of the fire extinguishing agent.

[0040] The pressure sensor 61 of the pressure monitoring assembly 6 monitors the pressure in the valve cavity 2 in real time. Its measuring end extends into the valve cavity 2, and can directly obtain accurate pressure data, reducing the pressure loss that may be caused by the external measuring device. The pressure sensor 61 transmits the pressure signal to the pressure display 62. The pressure display 62, such as a liquid crystal display, displays the pressure data intuitively, which is convenient for on-site staff to view. At the same time, as a high-precision sensor with wireless data transmission, the pressure sensor 61 transmits the real-time pressure signal to the intelligent alarm system and the Internet of Things linkage system. The stabilizing layer 63 is filled and solidified with epoxy resin, which not only ensures that the pressure sensor 61 and the pressure display 62 are stably installed in the fixed groove to prevent displacement or damage, but also uses the elasticity of epoxy resin to absorb the vibration energy of the valve during operation, eliminate vibration interference, and improve measurement accuracy.

[0041] When the pressure sensor 61 detects that the pressure in the valve chamber 2 is lower than the preset range, the intelligent alarm system triggers the alarm mechanism and notifies relevant personnel in time. If the fire extinguishing agent bottle is disassembled or sprayed, resulting in abnormal pressure, the intelligent alarm system will record the abnormal pressure value and upload the abnormal event and specific time, pressure change data and other information to the cloud platform in real time, which is convenient for tracing responsibility and equipment management.

[0042] When the pressure in the valve cavity 2 rises abnormally, the pressure acts on the second diaphragm 81 of the safety component 8, causing the second diaphragm 81 to suddenly change in the direction of the safety plug 82. When the pressure exceeds a certain value, the second diaphragm 81 is punctured by the safety plug 82, and the gas in the valve cavity 2 is depressurized through the safety groove and the air vent 83, preventing the valve from being damaged due to excessive pressure, thereby ensuring the safety of the valve and the entire gas fire extinguishing system. In addition, the second diaphragm 81 can be punctured by rotating the safety plug 82 and adjusting its position, thereby achieving the adjustment of the valve warning pressure.

[0043] When a fire occurs and the fire extinguishing agent needs to be released, the corresponding driving device (such as an electromagnetic driving device) on the trigger connector 5 is started, puncturing the first diaphragm 43, so that the gas between the valve core assembly 3 and the valve cover assembly 4 is discharged, the valve is opened, and the air pressure at the bottom of the valve core assembly 3 is greater than the air pressure at the top of the valve core assembly 3, so that the valve core body 31 slides upward in the valve cavity 2, the fire extinguishing agent outlet 12 is opened, and the fire extinguishing agent enters the valve cavity 2 from the fire extinguishing agent inlet 11, and flows from the fire extinguishing agent outlet 12 to the fire extinguishing nozzle to perform the fire extinguishing operation. In this process, the amplitude reduction spring 72 in the amplitude reduction groove 71 at the top of the valve core assembly 3 is compressed, which plays a buffering role for the rapid movement of the valve core assembly 3, and prevents the valve core assembly 3 from directly hitting the valve cover assembly 4 and causing damage. After the fire extinguishing agent is sprayed, the pressure between the valve core assembly 3 and the fire extinguishing agent inlet 11 is less than the sum of the elastic force of the amplitude reduction spring 72 and the self-weight of the valve core assembly 3, and the valve core assembly 3 is pressed onto the limit step hole of the valve body 1, so that the valve is closed.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
