Description

Technical Field

[0001] The utility model belongs to the technical field of plastic welding, and in particular relates to an electric fusion sleeve. Background Art

[0002] Plastic welding technology is a practical technology widely used in various engineering and industrial fields. It connects two or more plastic products permanently by heating and pressurizing. As an auxiliary tool for plastic welding, the electric fusion sleeve works by heating the plastic pipe at the contact part by electric heating, and then connecting it into a whole by pressure. This welding method has the advantages of being fast, efficient and beautiful. For some materials, it can also provide better performance than traditional connection methods.

[0003] The existing electric fusion sleeves have poor wear resistance and corrosion resistance, which has a serious impact on their long-term stability. During long-term operation, the structure and performance of the electric fusion sleeves will gradually deteriorate, resulting in a significant increase in the safety hazards of the pipeline system. In addition, due to its poor corrosion resistance, the electric fusion sleeve is easily corroded by corrosive media such as moisture and chemicals. This corrosion will cause material aging and performance degradation, thereby significantly shortening its service life. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-4 , the technical solution provided by this embodiment is as follows:

[0025] A fusion sleeve comprises a sleeve body 1, the surface of which is provided with a protective mechanism 2, the protective mechanism 2 comprising a polymer wear-resistant layer 201 and an anti-corrosion coating 202, the polymer wear-resistant layer 201 is coated on the surface of the sleeve body 1, and the anti-corrosion coating 202 is coated on the surface of the polymer wear-resistant layer 201.

[0026] See also Figure 4 The material used for the polymer wear-resistant layer 201 is polyetheretherketone polymer material, and the material used for the anti-corrosion coating 202 is polyurea elastomer.

[0027] Specifically, the sleeve body 1 serves as the main structure of the entire electric fusion sleeve, and is used to connect the pipe and the tee to achieve tight connection and fixation, ensure the stability and safety of the pipeline system, ensure that the pipeline does not loosen or leak during welding, and improve the operating efficiency and service life of the pipeline system. The polymer wear-resistant layer 201 can enhance the wear resistance of the sleeve body 1, reduce damage caused by friction, extend the service life of the electric fusion sleeve, and improve its durability in harsh environments. The polyetheretherketone polymer material used has excellent wear resistance and corrosion resistance, and can effectively protect the sleeve body 1 from wear and corrosion. The anti-corrosion coating 202 can prevent corrosive media such as moisture and chemicals from invading the sleeve body 1, causing material aging or performance degradation, thereby improving the corrosion resistance of the electric fusion sleeve and ensuring that it can maintain stable performance in various environments. The polyurea elastomer is used as the anti-corrosion coating 202, and uses its excellent corrosion resistance and adhesion to provide additional protection for the sleeve body 1.

[0028] Embodiment 2:

[0029] See also Figure 1-3 Power terminals 3 are provided at both ends of the outer side of the sleeve body 1, a heating element is embedded inside the sleeve body 1, one end of the power terminal 3 is connected to the heating element, a protective cover 4 is provided on the outer side of the power terminal 3, the sleeve body 1 is a hollow structure, and the inner walls at both ends of the sleeve body 1 are provided with depressions.

[0030] Specifically, the power terminal 3 is used to connect the heating element of the electric fusion sleeve to the power supply, providing a stable power input for the heating element, ensuring that the heating element can work normally, thereby realizing the heating function of the electric fusion sleeve, melting the pipeline material, and achieving the purpose of welding. The protective cover 4 can protect the power terminal 3 from the influence of the external environment, such as dust, moisture, etc., to ensure the stability and safety of the electrical connection, effectively prevent the power terminal 3 from being damaged or short-circuited, and improve the safety of the use of the electric fusion sleeve. The sleeve body 1 adopts a hollow structure to accommodate the pipeline and the heating element, and the inner wall recess is used to fix the pipeline to ensure its close connection with the sleeve, thereby realizing efficient and reliable pipeline connection, reducing leakage and looseness problems during welding, and improving the operation efficiency of the pipeline system.

[0031] Working principle: The protective cover 4 protects the power terminal 3 from being affected by the external environment. When plastic pipe welding is required, first remove the protective cover 4. Then, ensure that the pipe and tee to be welded are correctly connected, and insert them into the sleeve body 1 of the electric fusion sleeve. Since the inner walls at both ends of the sleeve body 1 are provided with depressions, these depressions can effectively fix the pipe to ensure its stability and accurate alignment during the welding process. Next, connect the power terminal 3 to the power supply to provide power to the heating element of the electric fusion sleeve. One end of the power terminal 3 is connected to the heating element to ensure that the power can be effectively transmitted to the heating element. When the power is turned on, the heating element starts to work and generates heat. This Some heat is transferred to the contact surface of the pipe and the tee through the sleeve body 1, causing the plastic material on the contact surface to begin to melt. When the predetermined welding time and temperature are reached, the heating element stops working, and the molten plastic begins to cool and solidify to form a firm welding connection. After welding is completed, the polymer wear-resistant layer 201 and the anti-corrosion coating 202 play a key protective role. The polyetheretherketone polymer material of the polymer wear-resistant layer 201 has excellent wear resistance and corrosion resistance, and can effectively prevent the sleeve body 1 from being damaged by friction during the welding process. At the same time, the polyurea elastomer material of the anti-corrosion coating 202 can resist the erosion of corrosive media such as moisture and chemicals, ensuring that the sleeve body 1 can maintain its performance and stability in various environments.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
