Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipeline vibration control, in particular to a pipeline shock absorbing device. Background Art

[0002] The drain pipes in power plants are prone to vibration during operation, and the causes of vibration are often complex. When cracks appear in the internal partitions of the high-pressure heater, some steam directly enters the high-pressure heater drain through the partition leakage point, and passes from the drain pipe to the deaerator in a steam state. The steam and drain form a steam-water two-phase flow in the pipe, causing the normal drain pipe of the high-pressure heater to vibrate in the belt layer and the deaerator layer, accompanied by "water hammer" impact, causing the pipe to have intermittent impact vibration. This vibration will cause the connection effect of the pipe and valve connection parts to decrease or even fail, and indirectly cause the pipe seat to crack, the water pipe is affected and breaks, forcing the power plant to shut down for maintenance, which is likely to cause unnecessary economic losses.

[0006] The beneficial effects of the utility model are as follows: when the vibration caused by the steam-water two-phase flow occurs, the damper outputs force and the vibration is alleviated; under the impact of water hammer, the damper outputs force slowly, driving the entire shock absorbing assembly to shake slightly, and the vibration force is absorbed by the damper, pipe clamp and fixed base frame, so that the impact vibration caused by the water hammer is also alleviated, reducing the probability of pipeline damage due to vibration and increasing the service life of the pipeline.

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1 to 3 As shown, embodiment 1 of the utility model is a pipeline shock absorbing device, comprising two shock absorbing components 2 arranged on the surface of the pipeline 1; the shock absorbing component 2 comprises a pipe clamp 21 arranged on the outer wall of the pipeline 1, a damper 22 is arranged below the pipe clamp 21, and mounting plates 23 are fixedly installed at the movable end and the bottom of the damper 22, the mounting plate 23 at the movable end is fixedly connected to the pipe clamp 21, and the bottom surface of the mounting plate 23 at the bottom is provided with a fixed base frame 24 in contact with the ground.

[0021] When the vibration caused by the steam-water two-phase flow occurs, the damper 22 outputs force and the vibration is alleviated; under the impact of water hammer, the damper 22 outputs force slowly, driving the entire shock absorbing assembly 2 to shake slightly, and the vibration force is absorbed by the damper 22, the pipe clamp 21 and the fixed base frame 24, which also alleviates the impact vibration caused by the water hammer, reduces the probability of damage to the pipeline 1 due to vibration, and increases the service life of the pipeline 1.

[0022] Embodiment 2 of the utility model is a pipeline shock absorbing device. On the basis of embodiment 1, the pipe clamp 21 includes a fixing plate 211 detachably mounted on the top surface of the top mounting plate 23, a vertically placed horizontal plate 212 is fixedly mounted on the upper surface of the fixing plate 211, a semicircular fixing ring 213 is fixedly mounted on one end of the horizontal plate 212 away from the fixing plate 211, and two relative fixing rings 213 are fixed to the surface of the pipeline 1 by bolts.

[0023] The fixing plate 211 is detachably mounted on the top mounting plate 23, which means that during the installation process, the position and angle of the pipe clamp 21 can be flexibly adjusted according to the specific position and needs of the pipeline 1. The design of the cross plate 212 and the fixing ring 213 makes the installation process more intuitive and simple. You only need to align the fixing ring 213 with the pipeline 1 and fix it with bolts.

[0024] Embodiment 3 of the utility model is a pipeline shock absorbing device. Based on embodiment 1 or 2, the shock absorbing assembly 2 also includes a placement plate 25 fixedly mounted on the top of the damper 22, and a reinforcement plate 26 is detachably mounted between the placement plate 25 and the opposite side of the bottom mounting plate 23.

[0025] By providing the placement plate 25 and providing the reinforcement plate 26 between the placement plate 25 and the mounting plate 23 , the reinforcement plate 26 reinforces the damper 22 , thereby preventing the damper 22 from deforming itself in extreme cases.

[0026] Embodiment 4 of the present invention is a pipeline shock absorbing device. Based on Embodiment 2, the pipe clamp 21 further includes a connecting plate 214 fixedly mounted on the surfaces of opposite sides of the two transverse plates 212 .

[0027] The addition of the connecting plate 214 makes the connection between the two transverse plates 212 more secure, increases the overall stability of the pipe clamp 21 , and prevents possible displacement or vibration in the pipeline system, thereby ensuring the stability and safety of the pipeline 1 .

[0028] Embodiment 5 of the utility model is a pipeline shock absorbing device. Based on embodiment 2, a rubber pad 3 is fixedly installed on the surface of the side of the fixing ring 213 that contacts the pipeline 1.

[0029] The addition of the rubber pad 3 can significantly alleviate the direct contact pressure between the fixing ring 213 and the pipe 1. Since the fixing ring 213 is usually made of metal, the direct contact between the metal and the pipe 1 can easily cause the pipe 1 to be partially squeezed, deformed or worn. The rubber pad 3 can provide a soft buffer layer to reduce the negative impact of such direct contact, thereby extending the service life of the pipe 1.

[0030] Embodiment 6 of the present utility model is a pipeline shock absorbing device. Based on any one of embodiments 1 to 5, a dust cover 4 is fixedly sleeved on the surface of the damper 22 .

[0031] By providing the dust cover 4, the damper 22 can be dustproof and waterproof during operation, and other impurities can be prevented from entering the damping oil and affecting the damping effect.

[0032] Embodiment 7 of the utility model is a pipeline shock absorbing device. Based on any one of embodiments 1 to 6, the fixed base frame 24 includes an I-shaped bottom plate 241 set on the ground, and a positioning plate 242 is fixedly installed on the upper surface of the bottom plate 241. The bottom mounting plate 23 is detachably installed on the upper surface of the positioning plate 242.

[0033] The I-shaped base plate 241 is designed to have a large contact area and excellent load-bearing capacity, which can stably support the entire structure and effectively prevent shaking or tilting caused by uneven load. At the same time, the bottom mounting plate 23 is detachably mounted on the positioning plate 242, making the installation and disassembly process simple and quick, thereby improving work efficiency.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
