The utility model discloses a realize through following technical scheme:

the utility model provides a pipeline water hammer damping device, damping device connects at the pipeline end, including connecting the body, connect this internal passageway that link up and be the loudspeaker form around establishing, the tip of passageway is the entrance point, main aspects are the exit end, the entrance point and the terminal sealed butt joint of pipeline mutually of passageway, the inherent position that is close to the exit end of passageway is equipped with the buffer block, the inner of buffer block stretch into in the passageway and with the sealed contact of passageway inside wall, open at the outer end middle part of buffer block has a cushion chamber, open the cushion chamber bottom has a perforating hole and a plurality of blind hole, through the passageway of perforating hole intercommunication cushion chamber and connection body, the outer end of buffer block stretches out and carries out the shutoff to the cushion chamber outer end through a blind plate from the exit end of passageway.

Furthermore, a gasket is arranged between the outer end of the buffer block and the blind plate.

Furthermore, the blind plate is connected with an outlet flange plate at the outlet end of the connecting body through bolts.

Furthermore, the inlet end of the connecting body is connected with the pipeline through an inlet flange.

Furthermore, a flange disc is arranged at the outer end of the buffer block, and the buffer cavity is formed in the flange disc of the buffer block.

Furthermore, the buffer block is a rubber block.

Compared with the prior art, the utility model has the following advantages:

1. the utility model provides a pair of waterproof hammer damping device of pipeline installs the device at the end of pipeline, and it is equipped with the buffer block in the passageway of connecting the body to it has the cushion chamber to open in the outer end of buffer block, makes the buffer block have fine buffering effect. The bottom of the buffer cavity is provided with a through hole and a plurality of blind holes, the through hole is used for exhausting air in the buffer cavity, and the buffer effect can be further increased through the plurality of blind holes at the bottom of the buffer cavity, so that the pressure of liquid in the pipeline is reduced, the liquid in the pipeline is prevented from impacting the inner wall of the pipeline, strong vibration or noise generated on the pipeline system is avoided, the pipeline system is protected, and the safe operation of the whole pipeline system is ensured. The device has the advantages of simple structure, convenient and quick installation, low manufacturing cost and obvious effect.

2. The utility model provides a pair of pipeline water hammer damping device, it has increased the volume of whole cushion chamber through setting up the packing ring, has further increased buffering effect.

Drawings

Fig. 1 is a perspective exploded view of the present invention.

Fig. 2 is an assembled semi-sectional view of the present invention.

Reference numbers in the figures: the structure comprises a connecting body 1, a channel 2, an inlet flange plate 3, a buffer block 4, a flange plate 5, a buffer cavity 6, a through hole 7, a blind hole 8, a blind plate 9, a bolt 10, an outlet flange plate 11 and a gasket 12.

Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Referring to fig. 1 and 2, the embodiment discloses a pipeline water hammer-proof damping device, which is connected to the tail end of a pipeline and comprises a connecting body 1, wherein a channel 2 which is through from front to back and is horn-shaped is arranged in the connecting body 1, the small end of the channel 2 is an inlet end, the large end of the channel 2 is an outlet end, the inlet end of the channel 2 is in sealing butt joint with the tail end of the pipeline, and the inlet end of the connecting body 1 is connected with the pipeline through an inlet flange 3.

The position of the channel 2 near the outlet end is provided with a buffer block 4, and the buffer block 4 is a high-temperature and high-pressure resistant rubber block. The inner end of the buffer block 4 extends into the channel 2 and is in sealing contact with the inner side wall of the channel 2, a flange disc 5 is arranged at the outer end of the buffer block 4, and a buffer cavity 6 is formed in the middle of the flange disc 5. A through hole 7 and a plurality of blind holes 8 are formed in the bottom of the buffer cavity 6, the buffer cavity 6 is communicated with the channel 2 of the connecting body 1 through the through hole 7, the outer end of the buffer block 4 extends out of the outlet end of the channel 2 and plugs the outer end of the buffer cavity 6 through a blind plate 9, the blind plate 9 is connected with an outlet flange plate 11 of the outlet end of the connecting body 1 through a bolt 10, and a gasket 12 is arranged between the outer end of the buffer block 4 and the blind plate 9.

The during operation, rivers in the pipeline flow in the passageway 2 of connecting body 1, buffer block 4 in the passageway 2 can play fine cushioning effect to water pressure, and because the existence of the cushion chamber 6 of buffer block 4 outer end, make buffer block 4 have fine buffering effect, perforating hole 7 in the buffer block 4 is used for the exhaust of cushion chamber 6, the setting of a plurality of blind holes 8 and the setting of packing ring 12, whole cushion chamber 6's volume has been increased, further increase buffering effect, thereby effectively reduced the interior liquid pressure of pipeline, liquid produces the impact to pipeline inner wall in having avoided the pipeline, strong vibration or noise have been avoided producing to pipeline, thereby pipeline system has been protected.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
