AI Technical Summary
In fire sprinkler valves, when there is a lot of water accumulation, the water pressure inside the pipe is high, which will cause a large impact on the connection between the connecting pipe and the drain pipe, which may cause the connecting pipe to detach from the drain pipe, making it difficult for the water to drain normally.
By using two clamping plates and a threaded rod, the clamping plates move synchronously under the action of the threaded rod until the connecting pipe is completely clamped, preventing the connecting pipe from detaching from the drain pipe. The clamping stability is enhanced by structures such as rectangular rods, rubber plates, and screw hole blocks, ensuring that the accumulated water is discharged normally.
It effectively prevents the connecting pipe from detaching from the drain pipe, ensuring that accumulated water can be discharged normally, enhancing the stability of the connection, and avoiding detachment problems caused by water pressure impact.

[0002] The fire deluge valve is a control valve for achieving automatic water supply by controlling the fire water supply pipeline, which can respond quickly when a fire occurs, ensure that water flows into the fire extinguishing system in time, and send an alarm through a hydraulic alarm bell to provide timely support for fire fighting, and plays a crucial role in the fire fighting system.
[0003] During the operation of the fire deluge valve, the drain pipe can timely drain the accumulated water in the pipeline to prevent the excessive accumulated water from affecting the normal operation of the system, which is crucial for maintaining the stability and reliability of the fire fighting system. However, the accumulated water in the drain pipe cannot be directly drained, and generally needs to be connected to a connecting pipeline at one end of the drain pipe, and the accumulated water is drained to a designated position through the connecting pipeline. When there is a large amount of accumulated water, the water pressure inside the pipeline is large, which will cause a large impact on the connection between the connecting pipeline and the drain pipe, and thus may cause the connecting pipeline and the drain pipe to separate, which is not convenient for the normal drainage of the accumulated water.

During the extension and retraction process, the threaded rods will drive the clamping plates to move synchronously until the two clamping plates completely clamp the connecting pipe. This can provide auxiliary fixation between the drain pipe and the connecting pipe, which helps to prevent the connecting pipe from separating from the drain pipe, thus facilitating the normal drainage of accumulated water.
[0007] Preferably, a rectangular rod is fixedly connected to each of the two clamping plates on the opposite sides, and the outer surface of the rectangular rod is slidably connected to the inner wall of the L-shaped plate.

[0028] Example 1, referring to Figures 1-3As shown, this embodiment discloses a fire-fighting deluge valve, including a valve body 1. Connectors 2 are fixedly connected to the top and bottom of the valve body 1. Flanges 3 are fixedly connected to the opposite sides of the two connectors 2. A drain pipe 4 is fixedly connected to the outer surface of one of the connectors 2. A fixing device 5 is provided on the outer surface of the drain pipe 4. The fixing device 5 includes an auxiliary block 51. The outer surface of the drain pipe 4 is fixedly connected to the inner wall of the auxiliary block 51. L-shaped plates 52 are symmetrically fixedly connected to the outer surface of the auxiliary block 51. Threaded rods are threadedly connected to the inner wall of the L-shaped plates 52. 53. Two threaded rods 53 are rotatably connected to their adjacent ends by clamps 54. The two clamps 54 are located on both sides of the outer surface of the drain pipe 4. A pressure gauge 6 is installed at the bottom of the valve body 1. An auxiliary pipe 7 is fixedly connected to the outer surface of the valve body 1. A hydraulic alarm bell 8 is fixedly connected to one end of the auxiliary pipe 7, and a pressure switch 10 is fixedly connected to the other end. A protective device 9 is installed on the outer surface of the hydraulic alarm bell 8. By setting the two clamps 54, under the action of the two threaded rods 53, rotating the threaded rods 53 will cause the threaded rods 53 to... The inner wall of the valve body 1 expands and contracts. During the expansion and contraction process, the threaded rod 53 drives the clamping plate 54 to move synchronously until the two clamping plates 54 completely clamp the connecting pipe. This provides auxiliary fixation between the drain pipe 4 and the connecting pipe, which helps prevent the connecting pipe from separating from the drain pipe 4 and facilitates the normal discharge of accumulated water. The valve body 1 has an orifice plate inside to restrict water flow and pressure transmission. Under normal working conditions, the pressure water in the water supply pipe pushes the diaphragm inside the control valve body 1, which locks the valve disc on the valve seat and prevents water from flowing from the lower chamber into the upper chamber. This design ensures that the fire protection system remains dry in non-fire conditions, avoiding the risk of accidental spraying or freezing. When a fire occurs, the air pressure changes. This pressure change is reflected in the pressure gauge 6 and reduces the water pressure in the valve body 1 to below the water supply pressure through the pressure switch 10. Under the action of the water supply pressure, the diaphragm is pushed, the valve disc opens, and water flows from the water supply pipe into the distribution pipe to perform the fire extinguishing task. At the same time, the hydraulic alarm bell 8 emits an alarm signal under the action of pressure change to notify firefighters of the fire.
[0029] Reference Figure 2 and Figure 3As shown, rectangular rods 55 are fixedly connected to the opposite sides of the two clamping plates 54. The outer surface of the rectangular rods 55 is slidably connected to the inner wall of the L-shaped plate 52. By setting the rectangular rods 55, when the clamping plates 54 move under the action of the threaded rods 53, the clamping plates 54 will drive the rectangular rods 55 to slide synchronously on the inner wall of the L-shaped plate 52. The rectangular rods 55 can limit and guide the clamping plates 54. An operating block 56 is fixedly connected to the opposite ends of the two threaded rods 53. The outer surface of the operating block 56 is provided with protrusions. By setting the operating block 56, rotating the operating block 56 can drive the threaded rods 53 to rotate. At the same time, the protrusions on the outer surface of the operating block 56 can effectively increase the friction of the outer surface of the operating block 56, which has an anti-slip effect when rotating the operating block 56.
[0030] Reference Figure 2 and Figure 3 As shown, a threaded hole block 57 is threadedly connected to the outer surface of the threaded rod 53. The threaded hole block 57 is located between the clamping plate 54 and the L-shaped plate 52. By setting the threaded hole block 57 and rotating it, one side of the threaded hole block 57 abuts against one side of the L-shaped plate 52. The threaded hole block 57 can limit the end of the threaded rod 53 away from the drain pipe 4, and thus limit the clamping plate 54, which helps to prevent the clamping of the connecting pipe by the two clamping plates 54 from loosening. A rubber plate 58 is fixedly connected to the side of the two clamping plates 54 that are close to each other. One side of the rubber plate 58 is arc-shaped. By setting the rubber plate 58, it can replace one side of the clamping plate 54 to abut against the outer surface of the connecting pipe and increase the friction on one side of the clamping plate 54, making the clamping of the connecting pipe by the clamping plate 54 more stable.
[0031] Reference Figure 2 and Figure 4 As shown, the protective device 9 includes an extension plate 91. One end of the extension plate 91 is fixedly connected to the outer surface of the auxiliary pipe 7. A first cover plate 92 is fixedly connected to one side of the extension plate 91. A top plate 93 is fixedly connected to the top of the first cover plate 92. The top plate 93 and the extension plate 91 are respectively set at the top and bottom of the hydraulic alarm bell 8. A second cover plate 94 is set on one side of the top plate 93 and the extension plate 91. The first cover plate 92 and the second cover plate 94 are respectively set on both sides of the hydraulic alarm bell 8. Several through holes are evenly opened on one side of the first cover plate 92 and the second cover plate 94. By setting the first cover plate 92 and the second cover plate 94, under the joint action of the extension plate 91 and the top plate 93, the hydraulic alarm bell 8 can be shielded and protected. This helps to prevent debris from hitting or squeezing the hydraulic alarm bell 8, which would prevent the hydraulic alarm bell 8 from vibrating and making a sound. At the same time, the presence of the cover plate 92 and the second cover plate 94 facilitates the propagation of sound, thus helping to ensure that the hydraulic alarm bell 8 can make a sound normally.
[0032] Reference Figure 2 and Figure 4As shown, the top and bottom of the second cover plate 94 are symmetrically fixedly connected with slot blocks 95. Threaded pins 96 are inserted into the inner wall of the slot blocks 95. One end of each of the four threaded pins 96 is symmetrically fixedly connected to one side of the top plate 93 and the bottom plate, respectively. Nuts 97 are threadedly connected to the outer surface of the threaded pins 96. By setting four threaded pins 96, inserting them into the inner wall of the four slot blocks 95, and then rotating the nuts 97, one side of the nuts 97 presses against the slot blocks 95, thus fixing the second cover plate 94 and the bottom plate to the extension plate 91. At the same time, the second cover plate 94 is detachable, which facilitates the maintenance and repair of the hydraulic alarm bell 8. One end of each threaded pin 96 is fixedly connected to a round block 98. The outer diameter of the round block 98 is larger than the outer diameter of the threaded pin 96. By setting the round block 98, one end of the threaded pin 96 can be blocked, which helps to prevent the nuts 97 from easily detaching from the threaded pins 96 and causing them to be easily lost.
[0033] Working principle: Rotating the two operating blocks 56 causes the threaded rod 53 to extend and retract within the L-shaped plate 52. Limited by the rectangular rod 55, the threaded rod 53, during its extension and retraction, causes the clamping plates 54 to move synchronously until the rubber plates 58 on one side of the two clamping plates 54 completely clamp the connecting pipe. Then, the screw hole block 57 is engaged, with one side of the screw hole block 57 abutting against one side of the L-shaped plate 52. The screw hole block 57 then limits the end of the threaded rod 53 away from the drain pipe 4, thereby limiting the clamping plates 54. This helps prevent the clamping plates 54 from loosening, thus providing auxiliary fixation between the drain pipe 4 and the connecting pipe, which is beneficial for preventing... To prevent the connecting pipe from separating from the drain pipe 4, thus facilitating the normal drainage of accumulated water; insert the four threaded pins 96 into the inner walls of the four slot blocks 95 respectively, and then rotate the nut 97 so that one side of the nut 97 presses against the slot block 95, thereby fixing the second cover plate 94 and the bottom plate and extension plate 91. Under the combined action of the extension plate 91 and the top plate 93, the first cover plate 92 and the second cover plate 94 can shield and protect the hydraulic alarm bell 8, which helps to prevent debris from hitting or squeezing the hydraulic alarm bell 8, causing the hydraulic alarm bell 8 to be unable to vibrate and emit sound. At the same time, the presence of the cover plate 92 facilitates the propagation of sound, thus helping to ensure that the hydraulic alarm bell 8 can emit sound normally.
