Description

Technical Field

[0001] This utility model relates to the field of fire hydrant casting technology, specifically to a fire hydrant casting with good corrosion resistance. Background Technology

[0002] The formal name for a fire hydrant is a fire hydrant, which is a fixed fire-fighting facility whose main function is to control combustibles, isolate oxidizers, and eliminate ignition sources.

[0003] According to patent document CN209529967U, a fire hydrant casting with good corrosion resistance is disclosed, including a fire hydrant pipe body, a rotating rod movably connected to the top of the fire hydrant pipe body, a handle fixedly connected to the top of the rotating rod, a connecting pipe connected to the right side of the fire hydrant pipe body, and a connector connected to the right side of the connecting pipe. The inner wall of the connecting pipe is provided with an anti-corrosion layer. This utility model solves the problem that existing fire hydrant castings will corrode and crack after long-term use, resulting in poor corrosion resistance, by using a combination of a fire hydrant pipe body, rotating rod, handle, connector, connecting pipe, input disc, anti-corrosion layer, aluminum tripolyphosphate coating layer, epoxy resin layer, and fluorocarbon coating layer. This improves the practicality of fire hydrant castings.

[0004] Currently, traditional fire hydrant castings do not have the function of preventing deformation during use. They often lack protective structures, so they are directly damaged when impacted, which affects their service life and makes them inconvenient to use. In addition, fire water often flows directly out of the fire water pipe through the valve pipe after it is discharged. The water still has a large initial force when it comes out of the valve pipe, which impacts the external water pipe and can easily affect the stability of the water pipe installation. Utility Model Content

[0005] The purpose of this utility model is to provide a fire hydrant casting with good corrosion resistance, in order to solve the problems mentioned in the background art. The traditional fire hydrant castings do not have the function of preventing deformation during use. Often, the fire hydrant castings lack protective structures, so they are directly damaged after being impacted, which affects the service life of the fire hydrant castings and makes them inconvenient for people to use. In addition, after the fire water is discharged, it often directly rushes out of the fire water pipe through the valve pipe. When the water is discharged from the valve pipe, it still has a large initial force, which impacts the external water pipe and easily affects the stability of the water pipe installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plug body is included, a valve tube is provided on the outer side wall of the plug body, a valve cover is provided at one end of the valve tube, a plug cover is detachably connected to the upper end of the plug body, a buffer mechanism is fixedly connected to the inner wall of the valve tube, a protective mechanism is fixedly connected to the outer wall of the plug body, and a connecting plate is welded to the lower end of the plug body.

[0007] The buffer mechanism includes a fixed base, the outer wall of which is fixedly connected to the inner wall of the valve pipe. A support rod is provided on one side of the fixed base, and a spring is provided on the outer wall of the support rod. A sliding plate is fixedly connected to one side of the support rod, and a buffer cylinder is sleeved on the outer wall of the sliding plate. A buffer disc is fixedly connected to one side of the buffer cylinder, and an outlet is provided on one side of the buffer disc.

[0008] Preferably, one side of the fixed seat is fixedly connected to one side of the support rod, and the outer wall of the support rod is sleeved with the inner wall of the spring.

[0009] Preferably, one side of the spring is fixedly connected to one side of the inner wall of the buffer cylinder, and the other side of the spring is fixedly connected to one side of the slide plate.

[0010] Preferably, one end of the valve tube is connected to the outer wall of the plug body, and one end of the valve cover is threadedly connected to one end of the valve tube.

[0011] Preferably, the protective mechanism includes a second spring, one end of which is fixedly connected to the outer wall of the bolt body, and the other end of the second spring is provided with a baffle. Side plates are provided on both sides of the baffle, and sliding holes are opened through the upper and lower ends of the side plates. A guide rod is slidably connected to the inner wall of the sliding hole. Limiting plates are fixedly connected to both sides of the guide rod. A third spring is sleeved on the outer wall of the guide rod. A rubber pad is adhered to the middle of the outer wall of the baffle, and a protective plate is fixedly connected to the outer wall of the rubber pad.

[0012] Preferably, one end of the second spring is fixedly connected to the inner wall of the baffle, and both sides of the baffle are fixedly connected to one side of the side plate.

[0013] Preferably, the spring is mounted on the guide rod and located between the two side plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The buffer mechanism helps prevent water pipe instability during installation. After water exits, it typically flows directly through the valve pipe into the fire hydrant. The initial force of the water impacts the external water pipe. The buffer plate then contacts the outlet, causing the buffer plate to slide and the buffer cylinder to slide. The buffer cylinder, cushioned by a spring, absorbs the initial force of the water exiting the valve pipe, reducing the impact on the connecting water pipe. This improves pipe stability, effectively absorbs energy, and minimizes damage to the internal structure. The combination of the spring and the buffer cylinder provides sufficient buffering force, ensuring stable operation of the hydrant in emergencies and preventing damage from severe impacts. This guarantees the reliability and safety of the fire hydrant in various environments.

[0016] 2. The protective mechanism effectively prevents the intrusion of external debris, thus protecting the fire hydrant casting from contamination and damage. In practical applications, the protective plate can withstand significant impact forces, while the elasticity of the rubber pad absorbs some of the impact energy, further protecting the normal operation of the fire hydrant. In addition, the combination of side plates and baffles ensures that under extreme conditions, such as earthquakes or impacts, the guide rod and limiting plate can restrict the displacement of the side plates, preventing excessive movement and damage. This greatly improves the durability and safety of the fire hydrant, allowing it to maintain good working condition in various complex environments. Furthermore, it enhances the impact resistance of the equipment, and the structure of the baffles and side plates effectively prevents foreign objects from damaging the fire hydrant casting.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: a fire hydrant casting with good corrosion resistance, including a hydrant body 1, a valve pipe 2 provided on the outer wall of the hydrant body 1, a valve cover 3 provided at one end of the valve pipe 2, a hydrant cover 4 detachably connected to the upper end of the hydrant body 1, a buffer mechanism 5 fixedly connected to the inner wall of the valve pipe 2, a protective mechanism 6 fixedly connected to the outer wall of the hydrant body 1, and a connecting plate 7 welded to the lower end of the hydrant body 1. The buffer mechanism 5 includes a fixed seat 51, the outer wall of the fixed seat 51 is fixedly connected to the inner wall of the valve pipe 2, a support rod 52 is provided on one side of the fixed seat 51, and a spring 53 is provided on the outer wall of the support rod 52. A slide plate 54 is fixedly connected to one side of the support rod 52. A buffer cylinder 55 is sleeved on the outer wall of the slide plate 54. A buffer disc 56 is fixedly connected to one side of the buffer cylinder 55. An outlet 57 is opened on one side of the buffer disc 56. One side of the fixed seat 51 is fixedly connected to one side of the support rod 52. The outer wall of the support rod 52 is sleeved with the inner wall of the spring 53. One side of the spring 53 is fixedly connected to one side of the inner wall of the buffer cylinder 55, and the other side of the spring 53 is fixedly connected to one side of the slide plate 54. One end of the valve pipe 2 is connected to the outer wall of the plug body 1. One end of the valve cover 3 is threadedly connected to one end of the valve pipe 2.

[0024] When fire-fighting water rushes into valve pipe 2, the water flow passes through outlet 57 and impacts buffer plate 56. This force causes buffer plate 56 to slide on support rod 52 and sliding plate 54, compressing and resetting spring 53. This buffering of the impact reduces the initial force on the fire-fighting water pipe and improves the stability of the pipe connection. The inner wall of spring 53 is fitted around support rod 52, providing effective elastic buffering force. Support rod 52 has a cylindrical shape, which facilitates the movement of buffer cylinder 55... The sliding mechanism on the buffer cylinder 55 improves ease of use. The inner wall of the buffer cylinder 55 is a cylindrical cavity structure, providing sufficient space for the sliding plate 54 to move and buffer. The outer wall of the sliding plate 54 slides along the inner wall of the buffer cylinder 55, which facilitates stable sliding. The outlet 57 is conical in shape, which facilitates effective contact and diversion of fire water. Through this design, the fire hydrant casting can effectively reduce the impact of water flow on the valve pipe 2 and the hydrant body 1 during use, extend the service life of the equipment, and at the same time have good corrosion resistance.

[0025] Please see Figure 1 , Figure 3 and Figure 4The protective mechanism 6 includes a second spring 61. One end of the second spring 61 is fixedly connected to the outer wall of the bolt body 1. The other end of the second spring 61 is provided with a baffle 62. Side plates 63 are provided on both sides of the baffle 62. The upper and lower ends of the side plates 63 are provided with sliding holes 64. The inner wall of the sliding holes 64 is slidably connected to a guide rod 65. Limit plates 66 are fixedly connected to both sides of the guide rod 65. A third spring 67 is sleeved on the outer wall of the guide rod 65. A rubber pad 68 is adhered to the middle of the outer wall of the baffle 62. A protective plate 69 is fixedly connected to the outer wall of the rubber pad 68. One end of the second spring 61 is fixedly connected to the inner wall of the baffle 62. Both sides of the baffle 62 are fixedly connected to one side of the side plate 63. The third spring 67 is sleeved on the guide rod 65 and located between the two side plates 63.

[0026] When baffle 62 is subjected to force, protective plate 69 and rubber pad 68 provide initial cushioning of the impact force. Subsequently, protective plate 69 drives baffle 62 to move, causing spring 61 to deform and providing secondary cushioning of the impact force. Simultaneously, the movement of baffle 62 drives side plate 63 to move accordingly, which in turn causes sliding hole 64 to slide on the surface of guide rod 65. The movement of side plate 63 causes spring 67 to deform, providing tertiary cushioning of the impact force. Side plate 63 has two sliding holes 64 inside its cavity. The inner diameter of sliding hole 64 is larger than the outer diameter of guide rod 65, and the inner wall of sliding hole 64 is slidably connected to the outer wall of guide rod 65. Limiting plates 66 are fixedly connected to both the front and rear ends of guide rod 65. The cross-sectional area of ​​the inner side of limiting plate 66 is larger than the cross-sectional area of ​​the outer side of guide rod 65. The limiting plates 66... The protective mechanism 6 effectively prevents the side plate 63 from sliding off the outer wall of the guide rod 65, thereby improving the stability of the side plate 63 during operation. In practical applications, when the hydrant body 1 is subjected to external impact, the protective mechanism 6 can effectively absorb and disperse the impact force, performing multiple buffering actions. When the spring 67 is subjected to pressure, it will be compressed, and the baffle 62 will move inward accordingly. The side plate 63 will slide under the guidance of the guide rod 65, and the spring 61 will be compressed for buffering. The rubber pad 68 and the protective plate 69 can effectively reduce the damage of external force to the hydrant body 1, playing a protective role. At the same time, the limiting plate 66 can limit the movement range of the guide rod 65, ensuring that the side plate 63 will not be excessively displaced when subjected to impact, thereby protecting the entire fire hydrant casting from damage. In addition, the presence of the spring 67 further enhances the buffering performance of the protective mechanism 6, ensuring that the fire hydrant casting can still maintain its structural integrity and functionality under extreme conditions.

[0027] Working principle: Firstly, when fire-fighting water rushes into valve pipe 2, the water flow through outlet 57 impacts the buffer plate 56. The buffer plate 56, under pressure, causes the buffer cylinder 55 to slide on the support rod 52 and sliding plate 54, compressing and resetting the spring 53. This buffers the impact force, reducing the initial force on the fire-fighting water pipe and improving the stability of the pipe connection. The inner wall of spring 53 is fitted onto the support rod 52, providing effective elastic buffering force. The overall cylindrical structure of the support rod 52 facilitates... The buffer cylinder 55 slides on the buffer cylinder 55 to improve ease of use. The inner wall of the buffer cylinder 55 is a cylindrical cavity structure, which provides enough space for the sliding plate 54 to move and buffer. The outer wall of the sliding plate 54 slides along the inner wall of the buffer cylinder 55, which is conducive to stable sliding. The outlet 57 is conical in shape, which is conducive to effective contact and diversion of fire water. Through this setting, the fire hydrant casting can effectively reduce the impact of water flow on valve pipe 2 and hydrant body 1 during use, extend the service life of the equipment, and at the same time have good corrosion resistance.

[0028] Then, the force applied to the baffle 62 causes the protective plate 69 and rubber pad 68 to buffer the impact force once. Subsequently, the protective plate 69 drives the baffle 62 to move, and the movement of the baffle 62 causes the second spring 61 to deform, which in turn buffers the impact force a second time. At this time, the movement of the baffle 62 simultaneously drives the side plate 63 to move accordingly, and the side plate 63 causes the sliding hole 64 to slide on the surface of the guide rod 65. The movement of the side plate 63 causes the third spring 67 to deform, which in turn buffers the impact force a third time. The inner cavity of the side plate 63 has two sliding holes 64, the inner diameter of which is larger than the outer diameter of the guide rod 65, and the inner wall of the sliding hole 64 is slidably connected to the outer wall of the guide rod 65. The front and rear ends of the guide rod 65 are fixedly connected to limit plates 66, the cross-sectional area of ​​the inner side of the limit plate 66 is larger than the cross-sectional area of ​​the outer side of the guide rod 65. The limit plate 66 effectively prevents the side plate 63 from sliding out of the outer wall of the guide rod 65. The stability of the side plate 63 during operation is improved. In practical applications, when the hydrant body 1 is impacted by external force, the protective mechanism 6 can effectively absorb and disperse the impact force, performing multiple buffering actions. Spring 67 is compressed under pressure, and baffle 62 moves inward accordingly. The side plate 63 slides under the guidance of guide rod 65, and spring 61 is compressed for buffering. The rubber pad 68 and protective plate 69 effectively reduce the damage of external force to the hydrant body 1, playing a protective role. At the same time, the limiting plate 66 can limit the movement range of guide rod 65, ensuring that the side plate 63 will not be excessively displaced when impacted, thereby protecting the entire fire hydrant casting from damage. In addition, the presence of spring 67 further enhances the buffering performance of the protective mechanism 6, ensuring that the fire hydrant casting can still maintain its structural integrity and functionality under extreme conditions. The above is the working process of the entire device, and the contents not described in detail in this specification are all prior art known to those skilled in the art.
