[0016] In order to make the purpose, technical scheme and beneficial effect of the utility model more clearly, the preferred embodiment of the utility model will be explained in detail below, to facilitate the understanding of technical personnel.

[0017] The utility model discloses a kind of disc pipe structure of water hammer of surface cooler, heating coil, the disc pipe structure of water hammer of surface cooler, heating coil mainly includes mounting plate 1, conveying straight pipe 2, connecting elbow pipe 3, inlet pipe 4, outlet pipe 5, baffle 6, the mounting plate 1 is provided with two groups, mounting plate 1 is provided with the screw hole 11 of being convenient for connection, conveying straight pipe 2 is installed at equal intervals between mounting plate 1, connecting elbow pipe 3 is interconnected between conveying straight pipe 2, inlet pipe 4 is connected with the topmost conveying straight pipe 2, outlet pipe 5 is connected with the bottommost conveying straight pipe 2, baffle 6 is installed in connecting elbow pipe 3, inlet pipe 4, outlet pipe 5 interior, baffle 6 is provided with the round hole 61 of being convenient for liquid to pass.

[0018] As Figure 6 Shown, the conveying straight pipe 2 is provided as double-wall bellows;Double-wall bellows absorbs or disperses the energy generated by water hammer, protects conveying straight pipe 2 from damage.

[0019] As Figure 1 , Figure 2 , Figure 3As shown, a pressure reducing valve 7 is installed at the water inlet pipe 4; the pressure reducing valve 7 is used to slow down the flow rate change and reduce the water hammer pressure.

[0020] Working process:

[0021] The mounting plate 1 is used to fix the entire coil structure. The threaded hole 11 is convenient for fixing the mounting plate 1 on the surface cooler or heating coil system. The delivery straight pipes 2 are installed between the mounting plates 1 at equal intervals. The delivery straight pipes 2 are set as double-wall corrugated pipes. The double-wall corrugated pipes are used to absorb or disperse the energy generated by water hammer, which helps to absorb the vibration generated when the liquid flows and reduce the impact of water hammer. The connecting elbow 3 is used to connect the various delivery straight pipes 2 to form a continuous piping system. The water inlet pipe 4 is connected to the topmost delivery straight pipe 2. It is the entrance for water flow to enter the system. The pressure reducing valve 7 is installed at the water inlet pipe 4. Its function is to slow down the water flow speed to avoid Due to the sudden pressure change, water hammer occurs. The outlet pipe 5 is connected to the bottom of the straight delivery pipe 2 and is the outlet for water to leave the system. The baffle 6 is installed inside the connecting elbow 3, the water inlet pipe 4 and the outlet pipe 5. The circular hole 61 opened on it allows liquid to pass through, and the baffle 6 itself plays the role of slowing down the water flow speed, further reducing the impact of water hammer. When the system is working, the water flows into the water inlet pipe 4, is regulated by the pressure reducing valve 7, and flows through the straight delivery pipe 2 at a stable speed. Under the action of the straight delivery pipe 2, the connecting elbow 3 and the baffle 6, the water flow is further smoothly guided to the outlet pipe 5 and finally flows out of the system.
