Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher valves, in particular to a fire extinguisher valve which can be quickly repaired. Background Art

[0002] The fire extinguisher valve is an important part of the fire extinguisher, which is used to control the discharge and stop of the internal filling (such as fire extinguishing agent) of the fire extinguisher. It can be manually or automatically operated, depending on the type and design of the fire extinguisher. The valve is usually located between the inlet and outlet on the bottle body, and its function includes controlling the release speed and direction of the fire extinguishing agent to achieve effective fire extinguishing effect. Fire extinguisher valves can be divided into several types, including pressure valves, manual valves, pressure relief valves, and electric valves.

[0003] A pressure relief mechanism of a fire extinguisher valve is disclosed in a Chinese utility model patent with publication number CN219941647U, which specifically relates to the field of fire extinguisher pressure relief. The utility model comprises a fire extinguisher body, a handle is provided at the upper end of the fire extinguisher body, a nozzle is provided at the upper end of the fire extinguisher body, a pressure gauge is provided at the upper end of the fire extinguisher body, a pressure relief device is provided on the surface of the fire extinguisher body, the pressure relief device comprises a mounting seat, one end of the mounting seat is fixedly connected to the fire extinguisher body, a pressure relief port is opened on the surface of the mounting seat, the pressure relief port extends to the interior of the fire extinguisher body, and a ring plate is fixedly connected to one end of the inner wall of the pressure relief port.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the fire extinguisher nozzle is exposed to the outside for a long time, which will cause aging and cracking; the nozzle in the above-mentioned device is difficult to remove from the valve, making it inconvenient to inspect and replace the nozzle. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a fire extinguisher valve for quick maintenance.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a fire extinguisher valve for quick maintenance, comprising a valve body, a nozzle is arranged at one end of the valve body, a nozzle is sleeved on the outer wall of the nozzle, a nozzle is arranged at the end of the nozzle away from the nozzle, a connecting block is fixed to the lower surface of the nozzle, a lower fixing ring is fixed to the side wall of the connecting block, a mounting plate is fixed to the side wall of the lower fixing ring, a mounting frame is fixed to the upper surface of the mounting plate, a sliding hole is penetrated through the side wall of the mounting frame, a fixing component for fixing the nozzle is installed on the mounting frame, the fixing component comprises a slider slidably connected to the sliding hole, a threaded rod penetrated and arranged on the mounting frame and threadedly connected, an upper fixing ring rotatably connected to the lower end of the threaded rod and fixed to the side wall of the slider, and a rotating block fixed to the upper end of the threaded rod.

[0007] By adopting the above technical solution, when it is necessary to install the nozzle, the staff will put the nozzle on the nozzle so that the arc-shaped inner wall of the lower fixing ring abuts against the lower surface of the nozzle, and then rotate the threaded rod by the rotating block. Since the threaded rod is threadedly connected to the mounting frame, the threaded rod is rotationally connected to the upper fixing ring, and the slider is slidingly connected to the sliding hole, the upper fixing ring moves downward along the axial direction of the threaded rod, so that the upper fixing ring cooperates with the lower fixing ring and presses against the nozzle. When disassembling, the nozzle can be taken out from the nozzle by rotating the rotating block to move the upper fixing ring upward away from the nozzle, which is convenient for inspection and replacement of the nozzle.

[0008] Furthermore, the nozzle outer wall fixing sleeve is provided with a plurality of raised rings, and the inner walls of the upper fixing ring and the lower fixing ring are both provided with annular grooves matching with the raised rings.

[0009] By adopting the above technical solution, multiple raised rings cooperate with the annular grooves, thereby increasing the contact area between the upper fixing ring, the lower fixing ring and the nozzle, and reducing the probability of the nozzle falling off the nozzle.

[0010] Furthermore, the inner wall of the upper fixing ring and the inner wall of the lower fixing ring are both provided with an anti-slip layer.

[0011] By adopting the above technical solution, the anti-skid layer is made of rubber material, and its surface has a high friction coefficient. The anti-skid layer increases the friction between the inner walls of the upper fixing ring and the lower fixing ring, and reduces the probability of the nozzle rotating on the nozzle.

[0012] Furthermore, an annular rubber sheet is fixedly sleeved on the outer wall of the nozzle.

[0013] By adopting the above technical solution, the annular rubber sheet is made of rubber material, which is elastic. The nozzle and the nozzle cooperate and press against the annular rubber sheet, thereby reducing the wear between the nozzle and the nozzle.

[0014] Furthermore, a rubber gasket is sleeved on the threaded rod and is located between the rotating block and the mounting frame.

[0015] By adopting the above technical solution, the rubber gasket is made of rubber material, and the material has greater friction. The rotating block cooperates with the mounting frame and presses against the rubber gasket, which increases the friction between the rotating block and the mounting frame and reduces the probability of automatic rotation of the rotating block.

[0016] Furthermore, an end of the nozzle pipe away from the nozzle head is provided with an external thread, and the nozzle is sleeved on the nozzle pipe and threadably connected to the external thread.

[0017] By adopting the above technical solution, the nozzle is threadedly connected to the nozzle pipe, so that the nozzle and the nozzle pipe can be detachably connected, which is convenient for separate maintenance and replacement of the nozzle and the nozzle pipe.

[0018] Furthermore, the nozzle includes a rubber hose, a fluorescent layer wrapped around the outside of the rubber hose, and a protective layer wrapped around the outside of the fluorescent layer.

[0019] By adopting the above technical solution, the protective layer gradually wears out after a long time. During this process, the staff needs to regularly inspect the protective layer. When the protective layer needs to be replaced, the thickness of the protective layer is relatively thin. When the staff illuminates the protective layer, the light can easily pass through the protective layer and contact the fluorescent layer. At this time, the staff can directly receive the fluorescent signal, which reduces the difficulty of the staff to repair the nozzle.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, when the nozzle needs to be installed, the staff will put the nozzle on the nozzle, so that the arc-shaped inner wall of the lower fixing ring abuts against the lower surface of the nozzle, and then rotate the threaded rod through the rotating block. Since the threaded rod is threadedly connected to the mounting frame, the threaded rod is rotatably connected to the upper fixing ring, and the slider is slidably connected to the sliding hole, the upper fixing ring moves downward along the axial direction of the threaded rod, so that the upper fixing ring cooperates with the lower fixing ring and abuts against the nozzle. When disassembling, the nozzle can be taken out from the nozzle by rotating the rotating block to move the upper fixing ring upward away from the nozzle, which is convenient for inspection and replacement of the nozzle;

[0022] 2. In the present application, multiple raised rings cooperate with the annular grooves to increase the contact area between the upper fixing ring, the lower fixing ring and the nozzle, thereby reducing the probability of the nozzle falling off the nozzle;

[0023] 3. In the present application, the anti-skid layer is made of rubber material, and its surface has a high friction coefficient. The anti-skid layer increases the friction between the inner wall of the upper fixing ring and the inner wall of the lower fixing ring, and reduces the probability of the nozzle rotating on the nozzle.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-5 As shown, the embodiment of the present application discloses a fire extinguisher valve for quick maintenance, including a valve body 1, a nozzle 3, a nozzle 4, a connecting block 5, a lower fixing ring 6, a mounting plate 7, a mounting frame 8 and a fixing assembly 9.

[0032] The valve body 1 is a valve body 1 commonly used in the prior art and applicable to the present embodiment, and a nozzle 2 is arranged at one end of the valve body 1. The nozzle 3 is a hose-like structure, and the nozzle 3 is sleeved on the outer wall of the nozzle 2. The nozzle 4 is a nozzle 4 commonly used in the prior art and applicable to the present embodiment, and the nozzle 4 is arranged at one end of the nozzle 3 away from the nozzle 2. The connecting block 5 is a rectangular parallelepiped structure, and the connecting block 5 is fixed on the lower surface of the nozzle 2. The lower fixing ring 6 is a structure with a semicircular ring cross-section, and the lower fixing ring 6 is fixed on the side wall of the connecting block 5. The mounting plate 7 is a rectangular plate-like structure, and the mounting plate 7 is fixed on the side wall of the lower fixing ring 6. The mounting frame 8 is a plate-like structure with a U-shaped cross-section, and the mounting frame 8 is fixed on the upper surface of the mounting plate 7, and a sliding hole 81 is opened through the side wall of the mounting frame 8.

[0033] The fixing assembly 9 is mounted on the mounting frame 8 and is used to fix the nozzle 3. The fixing assembly 9 includes a slider 91, a threaded rod 92, an upper fixing ring 93 and a rotating block 94. The slider 91 is a rectangular parallelepiped structure, and the slider 91 is slidably connected with the sliding hole 81. The threaded rod 92 is a vertically arranged rod-shaped structure, and the threaded rod 92 is penetrated and arranged on the mounting frame 8 and is threadedly connected. The upper fixing ring 93 is rotatably connected with the lower end of the threaded rod 92, and the upper fixing ring 93 is fixed to the side wall of the slider 91. The rotating block 94 is fixed to the upper end of the threaded rod 92, and the axis of the rotating block 94 coincides with the axis of the threaded rod 92.

[0034] When it is necessary to install the nozzle 3, the staff will sleeve the nozzle 3 on the nozzle head 2 so that the arc-shaped inner wall of the lower fixing ring 6 abuts against the lower surface of the nozzle 3, and then rotate the threaded rod 92 by the rotating block 94. Since the threaded rod 92 is threadedly connected to the mounting frame 8, the threaded rod 92 is rotatably connected to the upper fixing ring 93, and the slider 91 is slidably connected to the sliding hole 81, the upper fixing ring 93 moves downward along the axial direction of the threaded rod 92, so that the upper fixing ring 93 cooperates with the lower fixing ring 6 and presses against the nozzle 3. When disassembling, it is only necessary to rotate the rotating block 94 to move the upper fixing ring 93 upward away from the nozzle 3, so that the nozzle 3 can be taken out from the nozzle head 2, which is convenient for inspection and replacement of the nozzle 3.

[0035] In order to reduce the probability of the nozzle 3 falling off from the nozzle 4, a plurality of raised rings 10 are fixedly provided on the outer wall of the nozzle 3, and annular grooves 11 cooperating with the raised rings 10 are provided on the inner walls of the upper fixed ring 93 and the lower fixed ring 6. The plurality of raised rings 10 cooperate with the annular grooves 11 to increase the contact area between the upper fixed ring 93, the lower fixed ring 6 and the nozzle 3, thereby reducing the probability of the nozzle 3 falling off from the nozzle 4.

[0036] In order to reduce the probability of the nozzle 3 rotating on the nozzle 4, the inner wall of the upper fixing ring 93 and the inner wall of the lower fixing ring 6 are both provided with an anti-slip layer 12. The anti-slip layer 12 is made of rubber material, and its surface has a high friction coefficient. The anti-slip layer 12 increases the friction between the inner wall of the upper fixing ring 93 and the inner wall of the lower fixing ring 6, thereby reducing the probability of the nozzle 3 rotating on the nozzle 4.

[0037] In order to reduce the wear between the nozzle 3 and the nozzle 2, an annular rubber sheet 13 is fixedly sleeved on the outer wall of the nozzle 2. The annular rubber sheet 13 is made of rubber material, and the material is elastic. The nozzle 3 cooperates with the nozzle 2 and presses against the annular rubber sheet 13, thereby reducing the wear between the nozzle 3 and the nozzle 2.

[0038] In order to reduce the probability of the rotating block 94 rotating automatically, a rubber gasket 14 is sleeved on the threaded rod 92 and is located between the rotating block 94 and the mounting frame 8. The rubber gasket 14 is made of rubber material, and the material has a large friction. The rotating block 94 cooperates with the mounting frame 8 and presses against the rubber gasket 14, which increases the friction between the rotating block 94 and the mounting frame 8, thereby reducing the probability of the rotating block 94 rotating automatically.

[0039] In order to facilitate the separate maintenance and replacement of the nozzle 4 and the nozzle pipe 3, an external thread 15 is provided at the end of the nozzle pipe 3 away from the nozzle head 2. The nozzle 4 is sleeved on the nozzle pipe 3 and threadedly connected to the external thread 15. The nozzle head 2 is threadedly connected to the nozzle pipe 3, so that the nozzle 4 and the nozzle pipe 3 can be detachably connected, thereby facilitating the separate maintenance and replacement of the nozzle 4 and the nozzle pipe 3.

[0040] In order to reduce the difficulty for the staff to repair the nozzle 3, the nozzle 3 includes a hose 31, a fluorescent layer 32 coated on the outside of the hose 31, and a protective layer 33 coated on the outside of the fluorescent layer 32. The protective layer 33 gradually wears out over a long period of time. During this process, the staff needs to regularly inspect the protective layer 33. When the protective layer 33 needs to be replaced, the thickness of the protective layer 33 is relatively thin. When the staff irradiates the protective layer 33, the light can easily pass through the protective layer 33 and contact with the fluorescent layer 32. At this time, the staff can directly receive the fluorescent signal, thereby reducing the difficulty for the staff to repair the nozzle 3.

[0041] The use principle of a fire extinguisher valve for quick maintenance in the present embodiment is as follows: when the nozzle 3 needs to be installed, the staff will sleeve the nozzle 3 on the nozzle head 2 so that the arc-shaped inner wall of the lower fixing ring 6 abuts against the lower surface of the nozzle 3, and then rotate the threaded rod 92 by the rotating block 94. Since the threaded rod 92 is threadedly connected to the mounting frame 8, the threaded rod 92 is rotationally connected to the upper fixing ring 93, and the slider 91 is slidingly connected to the sliding hole 81, the upper fixing ring 93 moves downward along the axial direction of the threaded rod 92, so that the upper fixing ring 93 cooperates with the lower fixing ring 6 and abuts against the nozzle 3. When disassembling, it is only necessary to rotate the rotating block 94 to move the upper fixing ring 93 upward away from the nozzle 3, so that the nozzle 3 can be taken out from the nozzle head 2, which is convenient for maintenance and replacement of the nozzle 3.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
