Description

Technical Field

[0001] This utility model relates to the field of pipeline nozzle connection technology, and in particular, to a water distribution pipe nozzle connection structure. Background Technology

[0002] The water distribution system within a cooling tower typically includes distribution pipes and nozzles. The distribution pipes consist of main pipes and branch pipes, with nozzles installed on both. During operation, industrial circulating water, driven by a pump, enters the main pipe, then the branch pipes, and finally is sprayed downwards from the nozzles. This water exchanges heat with the rising dry, cool air inside the tower, thus lowering the temperature of the circulating water. To facilitate nozzle installation, a steel nozzle connection pipe is usually installed on the distribution pipe. This connection pipe is typically threaded; installing the nozzle simply involves screwing it onto the connection pipe. Traditionally, the nozzle connection pipe is welded to the distribution pipe. However, after welding, the connection pipe protrudes from the outer surface of the distribution pipe, making it susceptible to damage during transportation and hindering packaging and transport. Furthermore, welding requires highly skilled and experienced operators and increases production costs for the company. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a water distribution pipe nozzle connection structure that is easy to transport and assemble is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a water distribution pipe nozzle connection structure, including a water distribution pipe, a nozzle connecting pipe connected to the water distribution pipe, and a nozzle connected to the nozzle connecting pipe. A water outlet is provided on the side wall of the water distribution pipe. The inner cavity of the nozzle connecting pipe is aligned and communicates with the water outlet. One end of the nozzle connecting pipe extends outward to form a flange. A sealing gasket is sandwiched between the flange and the outer wall of the water distribution pipe. A bolt that can extend into the water distribution pipe from the water outlet is installed on the water distribution pipe. A through hole is provided on the side wall of the water distribution pipe at the side of the water outlet. The head of the bolt is located inside the water distribution pipe. The tail of the bolt passes through the through hole and the flange in sequence. A locking nut is installed on the tail of the bolt.

[0005] Furthermore, the central axis of the flange is collinear with the central axis of the nozzle connecting pipe, and the opposite sides of the flange protrude outward to form a connecting part. The connecting part is provided with a mounting hole, which is aligned with the through hole. The tail of the bolt passes through the through hole and then exits through the mounting hole.

[0006] Furthermore, the connecting part is smoothly connected to the flange.

[0007] Furthermore, the flange and the connecting part are integrally formed.

[0008] Furthermore, the surface of the flange that passes through the water distribution pipe is configured as an arc surface structure, and the arc surface structure is adapted to the outer surface of the water distribution pipe.

[0009] Furthermore, two bolts are installed on the flange, and the connection between the two bolts is arranged along the axial direction of the water distribution pipe.

[0010] Furthermore, a washer is fitted over the bolt, and the washer is pressed onto the flange by the locking nut.

[0011] Furthermore, each bolt is fitted with two locking nuts.

[0012] Furthermore, the nozzle connecting pipe is a threaded pipe, and the nozzle is threadedly connected to the nozzle connecting pipe.

[0013] Furthermore, the water distribution pipe includes a main pipe and branch pipes, and there are multiple branch pipes connected to the main pipe. The nozzle connection pipe is installed on both the main pipe and the branch pipes.

[0014] The beneficial effects of this utility model are as follows: The water distribution pipe nozzle connection structure of this utility model eliminates the protruding nozzle connecting pipe on the outer wall of the water distribution pipe during transport to the usage site, preventing damage from impacts and facilitating packaging and transportation.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figures 1-5 This utility model provides a water distribution pipe and nozzle connection structure, including a water distribution pipe 1, a nozzle connecting pipe 2, and a nozzle 3. The nozzle connecting pipe 2 is connected to the water distribution pipe 1, and the nozzle 3 is connected to the nozzle water distribution pipe 2. A water outlet 101 is provided on the side wall of the water distribution pipe 1. The inner cavity of the nozzle connecting pipe 2 is aligned and connected with the water outlet 101. One end of the nozzle connecting pipe 2 extends outward to form a flange 201. A sealing gasket 4 is sandwiched between the flange 201 and the outer wall of the water distribution pipe 1. A bolt 5 is installed on the water distribution pipe 1, which can extend into the interior of the water distribution pipe 1 through the water outlet 101. A through hole 102 is provided on the side wall of the water distribution pipe 1 at the side of the water outlet 101. The head of the bolt 5 is located inside the water distribution pipe 1, and the tail of the bolt 5 passes through the through hole 102 and the flange 201 in sequence. A locking nut 6 is installed on the tail of the bolt 5.

[0024] In the installation of the water distribution pipe nozzle connection structure of this utility model, the nozzle connecting pipe 2 is first placed on the outer wall of the water distribution pipe 1 corresponding to the water outlet 101, and a sealing gasket 4 is placed between the flange 201 and the outer wall of the water distribution pipe 1. Then, the bolt 5 is inserted into the water distribution pipe 1 through the inner cavity of the nozzle connecting pipe 2 and the water outlet 101. At this time, the tail of the bolt 5 passes through the through hole 102. Then, the locking nut 6 is installed on the tail of the bolt 5. By tightening the locking nut 6, the flange 201 is fixedly connected to the water distribution pipe 1. At the same time, after the sealing gasket 4 is deformed by pressure, it can play a good sealing role for the flange 201 and the water distribution pipe 1.

[0025] In the aforementioned water distribution pipe and nozzle connection structure, the outlet 101 and through hole 102 on the water distribution pipe 1 are pre-processed by the manufacturer before leaving the factory. The water distribution pipe 1 and nozzle connecting pipe 2 are then transported separately to the usage site, where they are assembled manually. During the transport of the water distribution pipe 1 to the usage site, the protruding nozzle connecting pipe 2 is not connected to the outer wall of the water distribution pipe 1, avoiding damage from impacts and facilitating packaging and transportation. Furthermore, during assembly, the operator only needs to insert the bolt 5 through the outlet 101 into the water distribution pipe 1, then pass it through the through hole 102 and the flange 201, and finally lock it in place using the lock nut 6. Compared to traditional welding methods, this method requires less technical skill and experience from the operator, is easier to install, and significantly reduces the company's production costs.

[0026] The flange 201 is roughly in the shape of a circular plate. The central axis of the flange 201 is collinear with the central axis of the nozzle connecting pipe 2. The flange 201 has connecting parts 202 protruding outward on opposite sides. The connecting parts 202 have mounting holes 203. The mounting holes 203 are aligned with the through holes 102. The tail of the bolt 5 passes through the through holes 102 and then out through the mounting holes 203.

[0027] Furthermore, the connecting portion 202 and the flange 201 are smoothly connected to reduce stress concentration at the connection point, thereby reducing cracks and fatigue and enhancing the strength and durability of the flange 201. In addition, the flange 201 and the connecting portion 202 are integrally formed, which facilitates processing and also helps to reduce production costs.

[0028] The surface of the flange 201 near the water distribution pipe 1 is set as an arc surface structure, which is adapted to the outer surface of the water distribution pipe 1 to ensure that the sealing gasket 4 is evenly pressed onto the outer wall of the water distribution pipe 1 by the flange 201.

[0029] In this embodiment, two bolts 5 are installed on the flange 201, and the line connecting the two bolts 5 is arranged along the axial direction of the water distribution pipe 1. It can be understood that in other embodiments not shown, the bolts 5 on the flange 201 may be more than three, which is not limited here.

[0030] The shape of the sealing gasket 4 is the same as the shape formed by the connection of the flange 201 and the connecting part 202. The bolt 5 passes through the sealing gasket 4. Thus, when the sealing gasket 4 is pressed against the outer wall of the water distribution pipe 1 by the flange 201, the sealing gasket 4 can seal the area around the bolt 5 between the flange 201 and the outer wall of the water distribution pipe 1, thereby preventing water flowing through the water distribution pipe 1 from leaking to the outside of the water distribution pipe 1 from the location of the connecting bolt 5, achieving a reliable seal. The sealing gasket 4 is made of silicone or rubber material. In addition, the sealing gasket 4 is set with an arc-shaped structure to adapt to the shape of the water distribution pipe 1.

[0031] A washer 7 is fitted over the bolt 5. The washer 7 is pressed against the flange 201 by the locking nut 6 to prevent the locking nut 6 from loosening easily. In this embodiment, the washer 7 is a flat washer.

[0032] Furthermore, each bolt 5 is equipped with two locking nuts 6, which further prevent the locking nuts 6 from easily coming off the bolt 5, thus improving the stability and reliability of the connection.

[0033] In this embodiment, the nozzle connecting pipe 2 is a threaded pipe, and the nozzle 3 is threadedly connected to the nozzle connecting pipe 2.

[0034] The water distribution pipe 1 includes a main pipe 11 and branch pipes 12. There are multiple branch pipes 12, which are connected to the main pipe 11. Sprinkler connection pipes 2 are installed on both the main pipe 11 and the branch pipes 12. During operation, part of the circulating water flowing through the main pipe 11 is sprayed downwards through the sprinklers 3 on the main pipe 11, while the other part of the circulating water enters the branch pipes 12 and is then sprayed downwards through the sprinklers 3 on the branch pipes 12.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
