Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher valve technology, and in particular to an improved fire extinguisher valve for preventing jet turbulence. Background Technology

[0002] As a core component of fire extinguishing systems, the performance of dry powder fire extinguisher valves directly affects extinguishing efficiency and operational reliability. In existing technologies, improvements to fire extinguisher valves to prevent jet turbulence primarily stabilize dry powder spray by optimizing the internal flow channel structure. However, in practical applications, while ensuring jet stability, valves also need to address the clogging problem caused by dry powder agglomeration to prevent structural failure and adapt to the needs of different fire extinguishing scenarios.

[0003] Currently, most conventional dry powder fire extinguisher valves employ a fixed flow channel design, using specific channel shapes or flow guiding structures to improve the flow characteristics of dry powder. Some improved valves have added buffer chambers and other devices to reduce pressure fluctuations during spraying. Furthermore, some valves use spring-assisted structures to regulate the dry powder flow rate and ensure spray stability. However, these designs primarily focus on jet optimization and lack sufficient measures to prevent dry powder agglomeration, while also lacking convenient pipeline replacement solutions.

[0004] However, existing technologies still have the following problems: traditional fire extinguisher valves designed to prevent jet turbulence do not have an effective filtration structure. When the dry powder in the fire extinguisher bottle clumps due to long-term storage, the clumps can easily enter the valve, causing blockage of the flow channel. This not only affects the spray effect and jet stability but also reduces the service life of the valve. Therefore, a fire extinguisher valve designed to prevent jet turbulence is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an improved fire extinguisher valve to prevent jet turbulence. The aim is to address the problem of clogged dry powder inside the fire extinguisher bottle being sprayed out due to the lack of a filter screen in the improved fire extinguisher valve, which causes blockage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An improved fire extinguisher valve for preventing jet turbulence includes a housing, a cavity one inside the housing, a cavity two inside the housing, and a filter assembly at the bottom of the housing.

[0008] The filter assembly includes a connecting block, a slider, a sliding plate, and a filter screen. The top of the connecting block is fixedly connected to the bottom of the housing, the bottom of the connecting block is fixedly connected to the sliding plate, the top of the sliding plate is slidably connected to the slider, and the outer wall of the slider is fixedly connected to the filter screen.

[0009] As a further description of the above technical solution:

[0010] A spray pipe is fixedly connected to the outer wall of the housing. A fixing block is fixedly connected to the outer wall of the spray pipe. A buckle plate is rotatably connected to the outer wall of the fixing block. A bolt is rotatably connected to the outer wall of the buckle plate. A quick-connect pipe is provided at one end of the spray pipe.

[0011] As a further description of the above technical solution:

[0012] A fixing block two is fixedly connected to the outer wall of the quick-connect pipe, a buckle hook is fixedly connected to one side of the fixing block two, and a sealing ring is fixedly connected inside the quick-connect pipe.

[0013] As a further description of the above technical solution:

[0014] A fixing arm is fixedly connected to the outer wall of the housing, and a top block is fixedly connected to the top of the housing.

[0015] As a further description of the above technical solution:

[0016] One end of the top block is rotatably connected to a rotating shaft, and a rotating arm is rotatably connected to the outer wall of the rotating shaft.

[0017] As a further description of the above technical solution:

[0018] A top rod is slidably connected to the bottom of the rotating arm. The top rod is slidably connected inside the top block and inside the housing.

[0019] As a further description of the above technical solution:

[0020] The top plate is fixedly connected to the bottom of the top rod, and the top plate is slidably connected inside the cavity. A spring is fixedly connected to the bottom of the top plate, and the bottom of the spring is fixedly connected inside the cavity.

[0021] As a further description of the above technical solution:

[0022] A safety bolt is slidably connected to the outer wall of the rotating arm. One end of the safety bolt is rotatably connected to a pull ring, and the other end of the safety bolt is rotatably connected to a bolt seal.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a connecting block is fixed at the bottom of the shell, and a sliding plate is connected to the bottom of the connecting block. A slider is fixed inside the filter screen. The slider is inserted into the gap between the sliding plates and the filter screen is rotated to one side to press the slider against one side of the connecting block. When the fire extinguisher is used, the dry powder clumped in the bottle will be blocked by the filter screen, thus preventing the dry powder clumped in from entering the valve. This solves the problem that the traditional fire extinguisher valve, which is improved to prevent jet turbulence, does not have a filter screen, which causes blockage when dry powder clumped in the fire extinguisher bottle is sprayed out. This improves the service life of the fire extinguisher valve improved to prevent jet turbulence.

[0025] 2. In this utility model, a quick-connect fitting is installed at one end of the spray pipe connected to the housing to replace the spray pipe and nozzle, so as to achieve different spraying effects. The outer wall of the spray pipe is rotatably connected to a buckle plate through a fixing block one, and a rotatable buckle is installed on its outer wall. The outer wall of the quick-connect fitting has a buckle hook fixed by a fixing block two. The quick-connect fitting is inserted into the spray pipe, and the buckle plate is rotated to fasten the buckle onto the buckle hook, thus achieving the function of replacing and fixing the spray pipe and nozzle. This solves the problem that the traditional fire extinguisher valve improved to prevent jet turbulence cannot replace the spray pipe and nozzle, resulting in the inability to use it in different operating environments. This improves the practicality and adaptability of the fire extinguisher valve improved to prevent jet turbulence. Attached Figure Description

The slider 15 is inserted into the gap between the sliding plate 14, and the filter screen 7 is rotated in one direction until the slider 15 is close to one side of the connecting block 16. The filter screen 7 is then installed at the bottom of the housing 1. At this time, the filter screen 7 can block the agglomerated part of the fire extinguishing medium that is about to pass through the internal cavity of the housing 1 to prevent the valve from being blocked.

[0036] Reference Figures 1-5A spray pipe 2 is fixedly connected to the outer wall of the casing 1. The extinguishing medium is sprayed from the spray pipe 2. A fixing block 17 is fixedly connected to the outer wall of the spray pipe 2. A snap-fit ​​plate 18 is rotatably connected to the outer wall of the fixing block 17. A snap-fit ​​bolt 19 is rotatably connected to the outer wall of the snap-fit ​​plate 18. Rotating the snap-fit ​​plate 18 can control the position of the snap-fit ​​bolt 19.

The spray pipe and nozzle are replaced with quick-connect pipe 3 to adapt to different usage scenarios. Insert quick-connect pipe 3 into spray pipe 2, rotate buckle plate 18 to fasten buckle 19 onto buckle hook 20 to complete the replacement. A sealing ring 22 is fixedly connected inside quick-connect pipe 3. The sealing ring 22 is used to seal the gap between quick-connect pipe 3 and spray pipe 2 after connection to prevent leakage of extinguishing medium. A fixed arm 6 is fixedly connected to the outer wall of housing 1, and a top block 8 is fixedly connected to the top of housing 1. A rotating shaft 4 is rotatably connected to one end of top block 8.
