Description

Technical Field

[0001] This utility model relates to the field of pipe positioning technology, and in particular to a pipe positioning device for a precooling water coil in a dual cold source system. Background Technology

[0002] Chilled water coils are core components in industrial machinery and equipment, manufactured using 304-grade welded steel pipes. They are primarily used in the machinery industry and as terminal heat exchange devices in central air conditioning systems. Through seamless manufacturing and a thin-walled design (50%-70% the wall thickness of copper pipes), these products achieve corrosion resistance and scale resistance, effectively extending equipment lifespan. As terminal equipment in chilled water systems, chilled water coils, along with fan coil units and modular air handling units, belong to the same category of central air conditioning terminal equipment.

[0003] When chilled water flows inside the coil, it comes into contact with the medium that needs cooling (such as air or equipment), absorbing heat through heat exchange and carrying away heat from the equipment or environment, thereby lowering the temperature. In a cooling system, chilled water coils can provide a cooling source for fan coil units, achieving indoor cooling. Currently, chilled water coils on the market use threaded connections, with threads and nuts at the connection points of the two steel pipe sections to connect the pipes. However, in actual use, threaded connections can loosen over time, leading to leaks and potentially causing short circuits within the cooling system. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning device for the precooling water coil in a dual-cold-source system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning device for the precooling water coil in a dual-cold source system includes a coil, with a fixedly connected inlet pipe at the upper end of the coil and a fixedly connected outlet pipe at the lower end of the coil. A slidable positioning mechanism is provided at the port of the inlet pipe. The positioning mechanism includes a slidable second connecting pipe and a movable limiting post. The second connecting pipe is located outside the inlet pipe, and the limiting post is located inside the second connecting pipe.

[0007] Preferably, the positioning mechanism includes a connecting ring, the outer wall of the water inlet pipe is provided with a fixedly connected connecting ring, the top of the connecting ring is provided with a fixedly connected first spring, and the first spring is wound around the outside of the water inlet pipe.

[0008] Preferably, the inlet pipe port is provided with a fixed first connecting pipe, the outer wall of the connecting ring is provided with a slidable second connecting pipe, and the first spring is located between the connecting ring and the second connecting pipe.

[0009] Preferably, the second connecting pipe has a first inclined groove at the end away from the coil, and movable limiting posts and a second spring are evenly provided on the wall of the first connecting pipe.

[0010] Preferably, the second spring is wound around the outside of the limiting post, and the inner wall of the second connecting tube abuts against the limiting post.

[0011] Preferably, a detachable third connecting pipe is provided above the first connecting pipe, and a fixedly connected guide pipe is provided inside the third connecting pipe. A fixedly connected rubber pad is provided at the port of the guide pipe near the water inlet pipe.

[0012] Preferably, a fourth connecting pipe is fixedly connected to the port of the third connecting pipe near the water inlet pipe, and a second inclined groove is formed on the outer wall of the fourth connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the positioning mechanism can reduce manual installation time. When the second connecting pipe slides down, the first spring is compressed, and the limiting post pops out into the first inclined groove. Then, the guide pipe is inserted into the first connecting pipe. When the second connecting pipe is released, the first spring returns to its elasticity, causing the second connecting pipe to move upward. The inner wall of the second connecting pipe abuts against the limiting post, and the second connecting pipe squeezes the limiting post. The limiting post is then stuck in the second inclined groove, and the guide pipe is fixed to the water inlet pipe. During later maintenance, the operator can directly disassemble the pipe, simplifying the maintenance process and significantly improving practicality and maintenance efficiency.

[0015] 2. In this utility model, a rubber pad is fixedly connected to the port of the guide pipe near the inlet pipe to prevent water leakage. The outlet pipe port can also be equipped with a positioning mechanism to connect to the drain pipe. The positioning mechanism is easy to disassemble, convenient and practical, and saves time and cost. Attached Figure Description

The inner wall of the second connecting pipe 22 abuts against the limiting post 241, and the limiting post 241 is stuck in the second inclined groove 252.
