[0029] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] See Figure 1-8This specific embodiment discloses a multi-functional valve head for fire-fighting agent bottles, including: a valve head body 2 spirally connected to a fire-fighting agent bottle 1, and a valve head cover 3 tightly connected to the valve head body. The valve head body 2 has a pressure gauge part 4, a filling part 5, a pressure relief part 6, an agent spraying part 7, a manual puncture part 8, and a temperature probe puncture part 9 on its side wall. The valve head body 2 has a first inner cavity 21 and a second inner cavity 22 that are interconnected. The inner diameter of the first inner cavity 21 is larger than that of the second inner cavity 22. A conical pressing member 23 is provided in the first inner cavity 21. The conical pressing member 23 abuts against the top of the second inner cavity 22. An elastic member 24 is fixedly connected between the conical pressing member 23 and the valve head cover 3. A pressure balance through hole 25 is opened at the axial position of the conical pressing member 23. The pressure balance through hole 25 is connected to the second inner cavity 22.

[0031] More specifically, the pressure gauge section 4, filling section 5, and pressure relief section 6 provided on the side wall of the valve head body are respectively connected to the second inner cavity 22 through the first internal conduction path (not shown in the figure), the manual puncture section 8 and the temperature probe puncture section 9 are respectively connected to the guide groove 211 provided at the top of the first inner cavity 21 through the second internal conduction path (not shown in the figure), and the agent spraying section 7 is connected to the lower part of the first inner cavity 21 through the third internal conduction path (not shown in the figure).

[0032] More specifically, the inner and outer surfaces of the second inner cavity 22 are both threaded, and a siphon tube 11 is provided inside the medicine bottle 1. The siphon tube 11 is threaded to the lower part of the second inner cavity 22, and the medicine bottle 1 is threadedly tightened to the outer end face of the second inner cavity 22.

[0033] In this specific embodiment, a pressure balance through hole 25 is opened at the axial position of the conical clamping member 23. This pressure balance through hole 25 allows the first inner cavity 21 and the second inner cavity 22 to be connected through the pressure balance through hole 25 when the multi-functional valve head is sealed. The conical clamping member 23 can abut against the top of the second inner cavity 22 under the action of the elastic member 24 to prevent the agent from entering the first inner cavity 21 and causing accidental spraying.

[0034] Furthermore, the multi-functional valve head integrates a pressure gauge 4, a filling section 5, a pressure relief section 6, a drug spraying section 7, a manual puncture section 8, and a temperature-sensing puncture section 9, enabling the valve head to function as a multi-functional unit: the pressure gauge 4 can characterize the pressure inside the drug bottle; when the pressure inside the bottle is too high, opening the pressure relief section 6 can reduce the pressure inside the bottle and protect the drug bottle; when the manual puncture section 8 or the temperature-sensing puncture section 9 punctures the diaphragm, the air pressure in the space above the conical clamping member 23 in the first inner cavity 21 is significantly reduced, the conical clamping member 23 is pushed upward, and the drug inside the drug bottle flows upward and is sprayed to the designated area through the drug spraying section.

[0035] Additionally, the pressure gauge section 4, filling section 5, and pressure relief section 6 provided on the side wall of the valve head body 2 are respectively connected to the second inner cavity 22 through the first internal conduction path (not shown in the figure), so that the pressure gauge section 4, filling section 5, and pressure relief section 6 can be directly connected to the medicine bottle 1 to directly represent the pressure inside the medicine bottle, or directly fill or depressurize the medicine bottle.

[0036] Furthermore, the manual puncture part 8 and the temperature probe puncture part 9 are connected to the guide groove 211 located at the top of the first inner cavity 21 through the second internal conduction path (not shown in the figure). The way in which the manual puncture part 8 and the temperature probe puncture part 9 are connected to the top of the first inner cavity 21 ensures that after the manual puncture part 8 and the temperature probe puncture part 9 puncture the membrane, the air pressure in the upper space of the first inner cavity 21 is significantly reduced. Therefore, the pressure in the medicine bottle 1 causes the conical clamping member 23 to move upward and causes the medicine to flow upward to the lower part of the first inner cavity 21, and then flow through the third internal conduction path to the medicine spray outlet for spraying.

[0037] More specifically, the valve head body 2 also has a venting section 10 on its side wall. The vent is connected to a vent hole 101 on the bottom end face of the valve head body via a fourth internal guiding path (not shown in the figure). A plug 102 is sealed to the vent hole. The venting section is designed to release pressure from the medicine bottle when operating in high-altitude terrain or in case of incorrect filling, where the pressure inside the medicine bottle increases significantly. It is worth noting that the pressure relief section and the venting section are different in that the pressure relief section is used to protect the medicine bottle and has a preset constant pressure relief value, while the venting section is used to release pressure at any value.

[0038] More specifically, the lower end of the conical clamping member has a protrusion 231, and a first sealing ring 232 is provided on the outer periphery of the protrusion 231. The protrusion 231 is inserted into the second inner cavity 22. By providing a protrusion 231 at the lower end of the conical clamping member and providing a first sealing ring 232 on the outer periphery of the protrusion, the sealing between the conical clamping member and the second inner cavity can be guaranteed.

[0039] More specifically, the manual puncture part 8 includes: a second locking block 81 threadedly connected to the valve head body 2; a third through hole 82 provided in the second locking block 81; a second diaphragm 83 provided at the end of the third through hole 82; a second puncture rod 84 inserted into the third through hole 82 with clearance fit; a second puncture needle 85 provided at the front end of the second puncture rod 84; a locking hole 86 coaxially opened between the second puncture rod 84 and the second locking block 81 in the radial position; and a locking pin 87 inserted into the locking hole 86.

[0040] More specifically, the temperature probe piercing part 9 includes: a first locking block 91 threadedly connected to the valve head body 2, the first locking block 91 having a stepped through hole 92, the stepped through hole 92 including a first through hole 921 and a second through hole 922 communicating with each other, the end of the second through hole 922 having a first diaphragm 93, the inner diameter of the first through hole 921 being larger than the inner diameter of the second through hole 922, a piston block 94 being inserted into the first through hole 921 with clearance fit, the piston block 94 having a first piercing rod 95 embedded and fixedly connected, the end of the first piercing rod 95 having a first piercing needle 96.

[0041] In this specific embodiment, the temperature probe piercing part is connected to the detection starter. When a fire occurs in the outside, the detection starter generates instantaneous high pressure. The instantaneous high pressure pushes the piston block of the temperature probe piercing part to move inward and forward. After the first piercing needle 96 connected to it passes through the second through hole 922 and pierces the first diaphragm 93, the instantaneous pressure in the medicine bottle pushes the piston block to move backward. Due to the gap fit, some gas overflows, which significantly reduces the gas pressure in the medicine bottle. The conical top clamping part 23 is lifted, and the multi-functional valve head is activated.

[0042] Alternatively, in an emergency, such as when the temperature probe cannot pierce the first diaphragm 93, the locking pin 87 can be pulled out and the second locking block 81 can be pushed forward. The second needle 85, which is connected to the second locking block 81, will penetrate the second diaphragm 83, thus significantly reducing the air pressure inside the multi-functional valve head and enabling manual activation of the multi-functional valve head in an emergency.

[0043] More specifically, the elastic element 24 is a spring. The spring uses its elastic force to press against the top of the threaded hole when the diaphragm is not pierced by the manual piercing part or the temperature probe piercing part, thus ensuring that the agent is not released.

[0044] More specifically, the first sealing ring 232 is made of EPDM and has an operating temperature range of -45°C to +150°C, making it suitable for different environments.

[0045] The working principle of this utility model:

[0046] This utility model proposes a multi-functional valve head for fire-fighting agent bottles, used in conjunction with a temperature-sensing activation device. The multi-functional valve head integrates a pressure gauge, filling section, pressure relief section, agent spraying section, manual puncture section, temperature-sensing puncture section, and venting section. In high-temperature situations such as fires, the temperature-sensing activation device used with the multi-functional valve head generates instantaneous high pressure. This instantaneous high pressure pushes the piston block inward, causing the first puncture needle connected to it to pierce the first diaphragm through the second through-hole. The air pressure inside the multi-functional valve head significantly decreases, the conical clamping member is lifted, the valve head is activated, and the agent is safely released. Alternatively, in emergency situations, the manual puncture section can be used directly to open the multi-functional valve head, allowing the agent in the bottle to be safely sprayed out. Furthermore, the pressure gauge, filling section, and pressure relief section can characterize the pressure of the agent bottle and adjust the filling pressure according to actual working conditions. The rubber ring inside the multi-functional valve head is made of ethylene propylene diene monomer (EPDM) rubber, with a temperature range of -45°C to +150°C, adapting to environmental requirements at different temperatures and greatly expanding its application scenarios and enhancing safety and convenience.
