Description

Technical Field

[0001] The utility model belongs to the technical field of water hammer prevention pipes, and particularly relates to a coil water inlet and outlet structure for a surface cooler or a heating coil to prevent water hammer. Background Art

[0002] Water hammer usually occurs when a fluid (such as water) suddenly stops or changes its flow direction in a pipeline. Due to the inertia of the fluid, instantaneous pressure fluctuations will be generated in the pipeline. This pressure fluctuation may cause serious damage to the pipeline system. In the coil inlet and outlet structures of the surface cooler and heating coil, the design of some coil inlet and outlet structures does not fully consider the impact of water hammer, which makes water hammer problems easy to occur in actual operation.

[0003] In the surface cooler and heating coil, if the water hammer phenomenon is serious, it may cause the coil to deform, rupture, and even affect the entire system. Therefore, a coil inlet and outlet structure for the surface cooler and heating coil is proposed to prevent water hammer. Summary of the Invention

[0004] In order to overcome the problems in the background technology, the utility model provides a coil inlet and outlet structure for surface coolers and heating coils to prevent water hammer; the fluid enters the water inlet diverter pipe through the guidance of the water inlet gradually expanding pipe and the guide plate, and the water inlet diverter pipe disperses the fluid so that the fluid is evenly distributed in the delivery straight pipe. The fluid flows in the delivery straight pipe, and the connection between different delivery straight pipes is achieved through connecting elbows to ensure that the fluid is evenly distributed in the entire system. Finally, the fluid flows out of the delivery straight pipe through the water outlet connecting pipe, enters the water outlet diverter pipe, gradually expands in the water outlet gradually expanding pipe, and finally flows out of the system.

[0005] To achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a coil inlet and outlet structure for a surface cooler and a heating coil to prevent water hammer mainly includes a mounting plate, a straight delivery pipe, a connecting elbow, a water inlet connecting pipe, a water inlet shunt pipe, a water inlet gradually expanding pipe, a guide plate, a water outlet connecting pipe, a water outlet shunt pipe, and a water outlet gradually expanding pipe. The mounting plates are provided with two groups, and threaded holes for easy connection are provided on the mounting plates. The straight delivery pipes are installed between the mounting plates at equal intervals. The connecting elbows connect the straight delivery pipes to each other. The inlet connecting pipe is installed at the end of the straight delivery pipe. The inlet shunt pipe is connected to the straight delivery pipe through the inlet connecting pipe. The water inlet gradually expanding pipe is installed on the inlet shunt pipe. The guide plates are installed inside the water inlet gradually expanding pipe at equal intervals. The outlet connecting pipe is installed at the end of the straight delivery pipe. The outlet shunt pipe is connected to the straight delivery pipe through the outlet connecting pipe. The water outlet gradually expanding pipe is installed on the outlet shunt pipe.

[0006] The straight conveying pipe is configured as a convergent-divergent pipe.

[0007] The guide plate is arranged in a semicircular structure.

[0008] Beneficial effects of the utility model:

[0009] The fluid enters the water inlet manifold through the guidance of the water inlet gradually expanding pipe and the guide plate. The water flow gradually expands in the water inlet gradually expanding pipe, which can effectively reduce the water flow velocity. The water inlet manifold disperses the fluid, balances the water flow pressure, and makes the fluid evenly distributed in the delivery straight pipe. The fluid flows in the delivery straight pipe, and the connection between different delivery straight pipes is achieved by connecting the elbows to ensure that the fluid is evenly distributed in the entire system. Finally, the fluid flows out of the delivery straight pipe through the water outlet connecting pipe, enters the water outlet manifold, gradually expands in the water outlet gradually expanding pipe, and finally flows out of the system. By rationally arranging the water inlet and outlet structures, effective control and guidance of the water flow is achieved, the system pressure is balanced, the water hammer phenomenon caused by pressure mutation is avoided, and the stability and reliability of the system are improved.

[0015] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0016] The utility model discloses a coil inlet and outlet structure for preventing water hammer of a surface cooler or a heating coil. The coil inlet and outlet structure for preventing water hammer of a surface cooler or a heating coil mainly comprises a mounting plate 1, a delivery straight pipe 2, a connecting elbow 3, a water inlet connecting pipe 4, a water inlet shunt pipe 5, a water inlet gradually expanding pipe 6, a guide plate 7, a water outlet connecting pipe 8, a water outlet shunt pipe 9, and a water outlet gradually expanding pipe 10. The mounting plate 1 is provided with two groups, and a threaded hole is provided on the mounting plate 1 for easy connection. The delivery straight pipe 2 and the like are provided with a plurality of threaded holes. The distance between the mounting plates 1 is installed, the connecting elbows 3 connect the delivery straight pipes 2 to each other, the water inlet connecting pipe 4 is installed at the end of the delivery straight pipe 2, the water inlet diverter 5 is connected to the delivery straight pipe 2 through the water inlet connecting pipe 4, the water inlet gradually expanding pipe 6 is installed on the water inlet diverter 5, the guide plates 7 are installed at equal intervals inside the water inlet gradually expanding pipe 6, the water outlet connecting pipe 8 is installed at the end of the delivery straight pipe 2, the water outlet diverter 9 is connected to the delivery straight pipe 2 through the water outlet connecting pipe 8, and the water outlet gradually expanding pipe 10 is installed on the water outlet diverter 9.

[0017] During the operation of the surface cooler or heating coil, the fluid enters the water inlet manifold 5 through the guidance of the water inlet gradually expanding pipe 6 and the guide plate 7. The water flow gradually expands in the water inlet gradually expanding pipe 6, which can effectively reduce the water flow velocity. The water inlet manifold 5 disperses the fluid, balances the water flow pressure, and makes the fluid evenly distributed in the delivery straight pipe 2. The fluid flows in the delivery straight pipe 2, and the connection between different delivery straight pipes 2 is achieved through the connecting elbow 3 to ensure that the fluid is evenly distributed in the entire system. Finally, the fluid flows out of the delivery straight pipe 2 through the water outlet connecting pipe 8, enters the water outlet manifold 9, gradually expands in the water outlet gradually expanding pipe 10, and finally flows out of the system. By reasonably arranging the water inlet and outlet structures, effective control and guidance of the water flow is achieved, the system pressure is balanced, the water hammer phenomenon caused by pressure mutation is avoided, and the stability and reliability of the system are improved.

[0018] like Figure 5 As shown, the straight delivery pipe 2 is configured as a convergent-divergent pipe; the convergent-divergent pipe is composed of contraction sections and expansion sections that alternate in sequence, so that the fluid always flows under the action of a longitudinal pressure gradient with repeatedly changing directions, thereby reducing the resistance of the fluid.

[0019] like Figure 4 As shown, the guide plate 7 is set to a semicircular structure; the guide plate 7 is set inside the water inlet gradually expanding pipe to guide the direction of water flow, so that the water flow enters the water inlet diverter pipe 5 more smoothly, and avoids the water flow directly impacting the pipe wall.

[0020] Working process:

[0021] First, fix the mounting plate 1 in an appropriate position to ensure that it is firm and reliable. During the operation of the surface cooler or heating coil, the fluid enters the water inlet manifold 5 through the guidance of the water inlet diffuser 6 and the guide plate 7. The water flow gradually expands in the water inlet diffuser 6, which can effectively reduce the water flow velocity. The water inlet manifold 5 disperses the fluid, balances the water flow pressure, and makes the fluid evenly distributed in the delivery straight pipe 2. The fluid flows in the delivery straight pipe 2, and the connection between different delivery straight pipes 2 is achieved through the connecting elbow 3 to ensure that the fluid is evenly distributed in the entire system. Finally, the fluid flows out of the delivery straight pipe 2 through the water outlet connecting pipe 8, enters the water outlet manifold 9, gradually expands in the water outlet diffuser 10, and finally flows out of the system. By reasonably arranging the water inlet and outlet structures, effective control and guidance of the water flow is achieved, the system pressure is balanced, the water hammer phenomenon caused by pressure mutation is avoided, and the stability and reliability of the system are improved.

[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
