Description

Technical Field

[0001] This utility model relates to the field of airtightness testing plug technology, and in particular to an airtightness testing plug for radiators. Background Technology

[0002] Air tightness testing of radiators is an important step in ensuring their sealing performance. Its purpose is to detect whether there is any gas leakage in the radiator, thereby ensuring its stability and reliability in actual use. Air tightness testing of radiators is a key quality control measure. By using professional testing equipment and strict operating procedures, the sealing performance of radiators can be effectively ensured, thereby improving their reliability and stability in practical applications. Usually, the air tightness test of radiators is carried out by sealing the water inlet with rubber or threaded plugs, which is inefficient and unsafe. The plugs can easily break out and injure people or damage the product. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] The present invention adopts the following technical solution: a radiator airtightness test plug, including a sleeve, wherein urethane is fixedly installed inside the sleeve, and a hexagonal nut is threadedly connected to the upper part of the sleeve, and a pressure plate is provided above the hexagonal nut.

[0005] Preferably, a cylinder is fixed to the upper end of the sleeve, and a return air pipe and an intake air pipe are connected to one side of the cylinder.

[0006] Preferably, the hexagonal nut is M22 and the pressure plate is M48.

[0007] Preferably, the return air pipe is located below the intake air pipe.

[0008] Preferably, the output end of the cylinder is connected to urethane rubber.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1

[0019] Please see Figure 1-3 This utility model provides a technical solution: a radiator airtightness testing plug, including a sleeve 1, with urethane 2 fixedly installed inside the sleeve 1. Urethane is a high-performance polyurethane (PU) elastomer material with excellent physical, chemical and mechanical properties. It lies between plastic and rubber, possessing both the rigidity of plastic and the elasticity of rubber. It has high toughness, high strength, and high rigidity, low density, and light weight, and exhibits good weather resistance and corrosion resistance. A hexagonal nut 3 is threadedly connected to the upper part of the sleeve 1. The hexagonal nut 3 is used to connect the cylinder 5 and the urethane rubber 2. A pressure plate 4 is positioned above the hexagonal nut 3 to cover and fix it. The cylinder 5 is fixed to the upper end of the sleeve 1. A return air pipe 6 and an intake air pipe 7 are connected to one side of the cylinder 5. The main function of the intake air pipe 7 is to deliver air or an air-fuel mixture from the intake manifold to the intake ports of each cylinder. The hexagonal nut 3 is M22, and the pressure plate 4 is M48. The return air pipe 6 is located below the intake air pipe 7. The output end of the cylinder 5 is connected to the urethane rubber 2.

[0020] Working principle: When in use, the sleeve 1 is pressed tightly against the radiator, and then the cylinder 5 is turned on. The cylinder 5 drives the urethane adhesive to test the airtightness of the radiator, and the pressure change is observed by other instruments.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
