Description

Technical Field

[0001] This utility model relates to the field of cooling triangular tube bundle technology, and in particular to a novel quick-connect device. Background Technology

[0002] The cooling triangular tube bundle, also known as the "cooling triangle," is a key component in an indirect air-cooled system. It is typically placed vertically at the bottom of the cooling tower. Air flows on the outside of the bundle, while cooling water is cooled inside.

[0003] When existing cooling triangular tube bundles leak, repairs are typically performed by inserting a secondary pipe. However, inserting a secondary pipe has two drawbacks: First, it affects cooling efficiency. The reduced diameter of the cooling tube bundle alters the original tube diameter, leading to uneven distribution of the cooling medium and preventing it from effectively adhering to the surface of the cooling triangle to remove heat, thus reducing cooling performance. Second, it may create new leak points. During the insertion process, friction, collisions, or improper installation can damage the bundle or secondary pipe itself. This damage may develop into new leak points during operation, further increasing the risk of equipment failure. Utility Model Content

[0004] The purpose of this invention is to solve at least one of the technical problems existing in the prior art by providing a novel quick-connect device. This device avoids reducing the number of operating tubes due to the addition of plugs and eliminates the need to remove the cooling triangle to install secondary liners, thus preserving the original primary tube bundle flow area and ensuring that the heat dissipation coefficient of the cooling triangle remains unchanged. It also features short maintenance time, simple process, and significantly reduced maintenance costs. The quick-connect method is convenient and low-cost, especially advantageous for cooling triangles with only a small number of primary tube bursts.

[0005] This utility model also provides a novel quick connector device, comprising: a sleeve body, two limiting protrusions fixedly connected to the outer side wall of the sleeve body, a magnetic block fixedly connected to the middle of each limiting protrusion, two limiting grooves provided inside each limiting protrusion, and mating threads provided on the upper and lower outer side walls of the sleeve body.

[0006] The sleeve body is connected to a nut by a mating thread. A gasket is movably connected inside the nut. A conical sealing ring is movably connected between the gasket and the sleeve body. A limit bracket is slidably connected inside each nut.

[0007] According to the novel quick connector device, each of the limiting grooves cooperates with the limiting frame, and the limiting protrusion can fix the limiting frame through the limiting groove, thereby restricting the rotation of the nut.

[0008] According to the novel quick connector device, the limiting frame is made of iron material, and the limiting frame cooperates with the magnetic block. The magnetic block can attract the limiting frame, thereby limiting the rotation of the limiting frame.

[0009] According to the novel quick-connect device, the conical sealing ring cooperates with the inner wall of the sleeve body, and the conical sealing ring can seal the upper or lower end of the sleeve body.

[0010] According to the novel quick coupling device, a limiting cap is fixedly connected to the side wall of the nut away from the sleeve body, and the limiting cap can effectively limit the position of the gasket.

[0011] According to the novel quick connector device, the sleeve body has two tubes to be connected inside, each of which is matched with a conical sealing ring, and the conical sealing ring matches the outer wall of the tube to be connected.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] Reference Figure 1-4 The present invention relates to a novel quick connector device, comprising: a sleeve body 1, two limiting protrusions 101 fixedly connected to the outer side wall of the sleeve body 1, a magnetic block 1012 fixedly connected to the middle of each limiting protrusion 101, two limiting grooves 1011 provided inside each limiting protrusion 101, mating threads 102 provided on the upper and lower outer side walls of the sleeve body 1, and two tubes 3 to be connected provided inside the sleeve body 1, each tube 3 to be connected mating with a conical sealing ring 4, the conical sealing ring 4 mating with the outer side wall of the tube 3 to be connected.

[0023] The sleeve body 1 is threadedly connected to a nut 2 via a mating thread 102. A washer 5 is movably connected inside the nut 2. A limit cover 202 is fixedly connected to the side wall of the nut 2 away from the sleeve body 1. The limit cover 202 can effectively limit the washer 5.

[0024] A conical sealing ring 4 is movably connected between the gasket 5 and the sleeve body 1. The conical sealing ring 4 cooperates with the inner wall of the sleeve body 1, and the conical sealing ring 4 can seal the upper or lower end of the sleeve body 1.

[0025] Each nut 2 has a slidingly connected limit frame 201 inside, and each limit groove 1011 cooperates with the limit frame 201. The limit protrusion 101 can fix the limit frame 201 through the limit groove 1011, thereby restricting the rotation of the nut 2. The limit frame 201 is made of iron material. The limit frame 201 cooperates with the magnetic block 1012. The magnetic block 1012 can attract the limit frame 201, thereby restricting the rotation of the limit frame 201.

[0026] Working principle: When repairing a leaking cooling triangular tube bundle, firstly, the burst point of the cooling triangular tube bundle is cut off. Then, a sleeve body 1 with the same diameter as the original finned tube is used for replacement, and a quick connector is used for connection. When connecting the quick connector, the sleeve body 1 is installed between the two cooling tube bundles. The nut 2 is pressed into the space between the sleeve body 1 and the cooling triangular tube bundle through the mating thread 102, thereby sealing the cooling triangular tube bundle and the conical sealing ring 4, and aligning the limiting groove 1011 with the limiting bracket 3. Finally, the limiting bracket 201 is slid into the limiting groove 1011, thereby limiting the loosening of the nut 2. The advantage of using this connection joint for repair is that it avoids reducing the number of operating tube bundles due to the addition of plugs, and it is not necessary to remove the cooling triangular tube bundle to install secondary liners. The original primary tube bundle flow area is preserved, ensuring that the heat dissipation coefficient of the cooling triangular tube remains unchanged. The repair time is short, the process is simple, and the repair cost is greatly reduced. Quick couplings offer convenient and low-cost repair methods, and are particularly advantageous for repairing cooling triangles with only a small number of primary tube bursts.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
