Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to an IG541 gas extinguishing system discharge control device. Background Technology

[0002] The existing IG541 gas extinguishing system includes an extinguishing agent cylinder with a container valve installed on it. The container valve is connected in sequence to a check valve, a selector valve, and a nozzle. A high-pressure metal hose connects the container valve and the check valve, and a manifold connects the check valve and the selector valve. Both the container valve and the selector valve are connected to a power cylinder and are activated by a pneumatic mechanism. However, using a power cylinder to drive the selector valve results in a complex structure and high operating costs. Therefore, finding alternative methods to drive the selector valve is currently one of the research topics.

[0003] There is a lot of research on selector valves, but less research on container valves. Even if selector valves do not rely on power cylinders, container valves still rely on power cylinders, and the entire system cannot completely eliminate power cylinders. Utility Model Content

[0004] The purpose of this invention is to provide an IG541 gas fire extinguishing system discharge control device to address the above problems. The entire system no longer requires a power gas cylinder, reducing system complexity and lowering costs.

[0005] To achieve the above objectives, this utility model discloses an IG541 gas extinguishing system discharge control device. The device includes a container valve installed on the extinguishing agent cylinder. The container valve is sequentially connected to a solenoid valve, a one-way valve, and a selector valve. The container valve includes a valve body with a gas passage for connecting the extinguishing agent cylinder and the solenoid valve. The valve body also has a valve core hole that communicates with the gas passage. A valve core is rotatably connected inside the valve core hole. A gas through hole is provided on the side of the valve core. When the gas through hole is perpendicular to the gas passage, the valve core closes the gas passage. When the gas through hole is parallel to the gas passage, the gas through hole communicates with the gas passage.

[0006] When the container valve does not need to be opened, rotate the valve core to align the gas through-hole with the gas passage, thus closing the gas passage. When the container valve needs to be opened, rotate the valve core to align the gas through-hole with the gas passage, thus connecting the gas through-hole to the gas passage.

[0007] Specifically, when the fire extinguishing system is in normal use, the container valve is opened. When a fire occurs, the solenoid valve and selector valve are opened to carry out fire extinguishing operations. When it is necessary to inspect the pipeline or replace the fire extinguishing agent cylinder, the container valve is closed.

[0008] This technical solution uses container valves and electromagnetically controlled solenoid valves to replace traditional pneumatic structures, and works in conjunction with electromagnetically controlled selector valves, so that the entire system no longer needs power cylinders, reducing system complexity and lowering costs.

[0009] Preferably, a valve core positioning hole is provided on the side of the valve core, and a first positioning pin and a second positioning pin are slidably connected on the valve body. A first reset device is provided between the first positioning pin and the valve body, and a second reset device is provided between the second positioning pin and the valve body. When the gas through hole is perpendicular to the gas channel, the valve core positioning hole cooperates with the second positioning pin. When the gas through hole is parallel to the gas channel, the valve core positioning hole cooperates with the first positioning pin.

[0010] When the valve core positioning hole engages with the second positioning pin, the container valve is in the closed state. When the valve core positioning hole engages with the first positioning pin, the container valve is in the open state. Because the valve core positioning hole engages with the second or first positioning pin, the torque required for the valve core to rotate is increased, which helps to maintain the stability of the valve core, avoids accidental rotation of the valve core that could cause abnormal operation of the container valve, and improves safety.

[0011] Preferably, the valve body has a first positioning pin through hole that communicates with the valve core hole. The end of the first positioning pin through hole away from the valve core hole is connected to a first limiting plate movable hole. A first cover plate is installed at the end of the first limiting plate movable hole away from the first positioning pin through hole. The front end of the first positioning pin can pass through the first positioning pin through hole. The side of the first positioning pin has a first limiting plate located in the first limiting plate movable hole. The first reset device includes a first spring located between the first limiting plate and the first cover plate.

[0012] When the first positioning pin does not mate with the valve core positioning hole, the front end of the first positioning pin abuts against the side of the valve core. At this time, the first limiting plate squeezes the first spring. When the valve core rotates, the valve core positioning hole rotates to the first positioning pin, and the first spring pushes the first limiting plate and the first positioning pin, so that the first positioning pin mates with the valve core positioning hole. This structure is simple and easy to use. At the same time, removing the first cover plate facilitates the installation of the first positioning pin and the first spring.

[0013] Preferably, the valve body is further provided with a second positioning pin through hole that communicates with the valve core hole. The end of the second positioning pin through hole away from the valve core hole is connected to a second limiting plate movable hole. A second cover plate is installed at the end of the second limiting plate movable hole away from the second positioning pin through hole. The front end of the second positioning pin can pass through the second positioning pin through hole. The side of the second positioning pin has a second limiting plate located in the second limiting plate movable hole. The second reset device includes a second spring located between the second limiting plate and the second cover plate.

[0014] When the second locating pin does not mate with the valve core locating hole, the front end of the second locating pin abuts against the side of the valve core. At this time, the second limiting plate squeezes the second spring. When the valve core rotates, the valve core locating hole rotates to the second locating pin, and the second spring pushes the second limiting plate and the second locating pin, so that the second locating pin mates with the valve core locating hole. This structure is simple and easy to use. At the same time, removing the second cover plate facilitates the installation of the second locating pin and the second spring.

[0015] Preferably, the rear end of the first locating pin can pass through the first cover plate, and the rear end of the second locating pin can pass through the second cover plate; when the valve core locating hole is engaged with the second locating pin, the rear end of the second locating pin is lower than or flush with the outer surface of the second cover plate, and the rear end of the first locating pin is higher than the first cover plate; when the valve core locating hole is engaged with the first locating pin, the rear end of the first locating pin is lower than or flush with the outer surface of the first cover plate, and the rear end of the second locating pin is higher than the second cover plate.

[0016] When the container valve is closed, the valve core positioning hole engages with the second positioning pin. The rear end of the second positioning pin is lower than or flush with the outer surface of the second cover plate, while the rear end of the first positioning pin is higher than the first cover plate. When the container valve is open, the valve core positioning hole engages with the first positioning pin. The rear end of the first positioning pin is lower than or flush with the outer surface of the first cover plate, while the rear end of the second positioning pin is higher than the second cover plate. Operators can observe the positions of the second positioning pin and the rear end of the first positioning pin to help determine the status of the container valve, especially when the valve core is driven to rotate by a motor or other equipment.

[0017] Preferably, the rear end of the first locating pin has a first mark, and the rear end of the second locating pin has a second mark.

[0018] The first marking makes the rear end of the first positioning pin more conspicuous, and the second marking makes the rear end of the second positioning pin more conspicuous. Operators can use the position of the rear ends of the second positioning pin and the first positioning pin to help determine the status of the container valve.

[0019] Preferably, the first identifier is green and the second identifier is red.

[0020] When in use, green indicates that the container valve is closed, and red indicates that the container valve is open, making it easier for operators to observe.

[0021] Preferably, the valve core is connected to an operating handle. When the gas through-hole is perpendicular to the gas channel, the operating handle is parallel to the second positioning pin. When the gas through-hole is parallel to the gas channel, the operating handle is parallel to the first positioning pin.

[0022] When in use, when the operating handle is rotated to the side of the second positioning pin, the position of the second positioning pin is blocked, while the position of the first positioning pin is not blocked. When the operating handle is rotated to the side of the first positioning pin, the position of the first positioning pin is blocked, while the position of the second positioning pin is not blocked, making it easier for the operator to observe.

[0023] Preferably, the front end of the first positioning pin is hemispherical, the front end of the second positioning pin is hemispherical, and the valve core positioning hole is hemispherical.

[0024] When in use, the front end of the first or second locating pin can easily engage or disengage with the valve core locating hole, making it convenient to use.

[0025] In summary, the beneficial effects of this utility model are as follows: by using a container valve and an electromagnetically controlled solenoid valve to replace the traditional pneumatic structure, and in conjunction with an electromagnetically controlled selector valve, the entire system no longer requires a power cylinder, reducing the complexity of the system and lowering costs.

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in further 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 its scope.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] like Figure 1 As shown, an IG541 gas fire extinguishing system discharge control device includes a container valve 2 installed on an extinguishing agent cylinder 1. The container valve 2 is sequentially connected to a solenoid valve 3, a check valve 5, a selector valve 7, and a nozzle 8. A high-pressure metal hose 4 connects the solenoid valve 3 and the check valve 5, and a manifold 6 connects the check valve 5 and the selector valve 7. Both the solenoid valve 3 and the selector valve 7 are electrically connected to a control unit 9. How the control unit 9 controls the opening and closing of the solenoid valve 3 and the selector valve 7 uses existing technology and will not be described further here.

[0032] like Figures 2 to 7As shown, the container valve 2 includes a valve body 201. The valve body 201 has a gas passage 207 for connecting the extinguishing agent cylinder 1 and the solenoid valve 3. The valve body 201 also has a valve core hole 205 communicating with the gas passage 207. A valve core 203 is rotatably connected within the valve core hole 205. A gas through hole 204 is provided on the side of the valve core 203. When the gas through hole 204 is perpendicular to the gas passage 207, the valve core 203 closes the gas passage 207. When the gas through hole 204 is parallel to the gas passage 207, the gas through hole 204 communicates with the gas passage 207. Figure 4 As shown, when container valve 2 does not need to be opened, the valve core 203 is rotated so that the gas through-hole 204 is perpendicular to the gas passage 207, and the valve core 203 closes the gas passage 207. Figure 6 As shown, when container valve 2 needs to be opened, the valve core 203 is rotated to make the gas through-hole 204 parallel to the gas channel 207, and the gas through-hole 204 and the gas channel 207 are connected. Specifically, when the fire extinguishing system is in normal use, container valve 2 is opened. When a fire occurs, solenoid valve 3 and selector valve 7 are opened to carry out fire extinguishing operations. When it is necessary to inspect the pipeline or replace the fire extinguishing agent cylinder 1, container valve 2 is closed.

[0033] This technical solution uses a container valve 2 and an electromagnetically controlled solenoid valve 3 to replace the traditional pneumatic structure, and works in conjunction with an electromagnetically controlled selector valve 7, so that the entire system no longer needs a power cylinder, reducing the complexity of the system and lowering costs.

[0034] Preferably, the valve core 203 has a valve core positioning hole 206 on its side, and a first positioning pin 209 and a second positioning pin 215 are slidably connected on the valve body 201. A first reset device is provided between the first positioning pin 209 and the valve body 201, and a second reset device is provided between the second positioning pin 215 and the valve body 201. When the gas through hole 204 is perpendicular to the gas channel 207, the valve core positioning hole 206 cooperates with the second positioning pin 215. When the gas through hole 204 is parallel to the gas channel 207, the valve core positioning hole 206 cooperates with the first positioning pin 209. When the valve core positioning hole 206 engages with the second positioning pin 215, the container valve 2 is in the closed state. When the valve core positioning hole 206 engages with the first positioning pin 209, the container valve 2 is in the open state. The engagement of the valve core positioning hole 206 with either the second or first positioning pin 209 increases the torque required for the rotation of the valve core 203, which helps maintain the stability of the valve core 203, preventing accidental rotation that could cause malfunctions in the container valve 2 and improving safety. The front ends of the first and second positioning pins 215 and valve core positioning hole 206 are hemispherical. This design facilitates the engagement and disengagement of the front ends of the first or second positioning pins 209 and 215 with the valve core positioning hole 206, making it convenient to use.

[0035] Preferably, the valve body 201 has a first positioning pin through hole 208 that communicates with the valve core hole 205. The end of the first positioning pin through hole 208 away from the valve core hole 205 is connected to a first limiting plate movable hole 210. The end of the first limiting plate movable hole 210 away from the first positioning pin through hole 208 is equipped with a first cover plate 213. The front end of the first positioning pin 209 can pass through the first positioning pin through hole 208. The side of the first positioning pin 209 has a first limiting plate 211 located in the first limiting plate movable hole 210. The first reset device includes a first spring 212 located between the first limiting plate 211 and the first cover plate 213. When the first positioning pin 209 does not engage with the valve core positioning hole 206, the front end of the first positioning pin 209 abuts against the side of the valve core 203. At this time, the first limiting plate 211 compresses the first spring 212. When the valve core 203 rotates, the valve core positioning hole 206 rotates to the position of the first positioning pin 209. The first spring 212 pushes the first limiting plate 211 and the first positioning pin 209, so that the first positioning pin 209 engages with the valve core positioning hole 206. This structure is simple and easy to use. At the same time, removing the first cover plate 213 facilitates the installation of the first positioning pin 209 and the first spring 212. The valve body 201 is also provided with a second positioning pin through hole 214 that communicates with the valve core hole 205. The end of the second positioning pin through hole 214 away from the valve core hole 205 is connected to a second limiting plate movable hole 216. A second cover plate 219 is installed at the end of the second limiting plate movable hole 216 away from the second positioning pin through hole 214. The front end of the second positioning pin 215 can pass through the second positioning pin through hole 214. The side of the second positioning pin 215 has a second limiting plate 217 located in the second limiting plate movable hole 216. The second reset device includes a second spring 218 located between the second limiting plate 217 and the second cover plate 219. When the second positioning pin 215 does not engage with the valve core positioning hole 206, the front end of the second positioning pin 215 abuts against the side of the valve core 203. At this time, the second limiting plate 217 compresses the second spring 218. When the valve core 203 rotates, the valve core positioning hole 206 rotates to the position of the second positioning pin 215. The second spring 218 pushes the second limiting plate 217 and the second positioning pin 215, so that the second positioning pin 215 engages with the valve core positioning hole 206. This structure is simple and easy to use. At the same time, removing the second cover plate 219 facilitates the installation of the second positioning pin 215 and the second spring 218.

[0036] The rear end of the first positioning pin 209 can pass through the first cover plate 213, and the rear end of the second positioning pin 215 can pass through the second cover plate 219. When the valve core positioning hole 206 is engaged with the second positioning pin 215, the rear end of the second positioning pin 215 is lower than or flush with the outer surface of the second cover plate 219, and the rear end of the first positioning pin 209 is higher than the first cover plate 213. When the valve core positioning hole 206 is engaged with the first positioning pin 209, the rear end of the first positioning pin 209 is lower than or flush with the outer surface of the first cover plate 213, and the rear end of the second positioning pin 215 is higher than the second cover plate 219. When the container valve 2 is in the closed state, the valve core positioning hole 206 engages with the second positioning pin 215. The rear end of the second positioning pin 215 is lower than or flush with the outer surface of the second cover plate 219, and the rear end of the first positioning pin 209 is higher than the first cover plate 213. When the container valve 2 is in the open state, the valve core positioning hole 206 engages with the first positioning pin 209. The rear end of the first positioning pin 209 is lower than or flush with the outer surface of the first cover plate 213, and the rear end of the second positioning pin 215 is higher than the second cover plate 219. The operator can observe the position of the rear ends of the second positioning pin 215 and the first positioning pin 209 to help determine the state of the container valve 2, especially when the valve core 203 is driven to rotate by a motor or other equipment.

[0037] Preferably, the rear end of the first positioning pin 209 has a first marking 220, and the rear end of the second positioning pin 215 has a second marking 221. The first marking 220 makes the rear end of the first positioning pin 209 more conspicuous, and the second marking 221 makes the rear end of the second positioning pin 215 more conspicuous. Operators can use the positions of the rear ends of the second positioning pin 215 and the first positioning pin 209 to help determine the status of the container valve 2. The first marking 220 is green, and the second marking 221 is red. Specifically, fluorescent material is used in the first marking 220 and the second marking 221. In use, green indicates that the container valve 2 is in the closed state, and red indicates that the container valve 2 is in the open state, making it easier for operators to observe.

[0038] Preferably, the valve core 203 is connected to an operating handle 202. When the gas through-hole 204 is perpendicular to the gas channel 207, the operating handle 202 is parallel to the second positioning pin 215. When the gas through-hole 204 is parallel to the gas channel 207, the operating handle 202 is parallel to the first positioning pin 209. In use, when the operating handle 202 is rotated to the side of the second positioning pin 215, the position of the second positioning pin 215 is blocked, while the position of the first positioning pin 209 is not blocked. When the operating handle 202 is rotated to the side of the first positioning pin 209, the position of the first positioning pin 209 is blocked, while the position of the second positioning pin 215 is not blocked, making it easier for the operator to observe.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
