Abstract
Description
Technical Field
[0001] The utility model relates to a pipe connecting device, in particular to a pipe connecting piece. Background Art
[0002] The connection of pipes is generally through hot melting, and the heat capacity is generally through electric fusion fittings. The electric fusion fittings are a very important connection joint in the connection of plastic pipes, which firmly weld the pipes in the same direction together. At present, most of the electric fusion sleeves in China are pure plastic injection molded electric fusion fittings such as PE and PE-RT. The connection between pure plastic electric fusion fittings and pipes is heated by the electric heating wire arranged on the inner wall of the socket of the pure plastic electric fusion fittings. First, the pipes and fittings are heated and expanded to eliminate the air between the outer wall of the pipe and the inner wall of the fittings. Then, the voltage supplied to the electric heating wire is increased to make the resin at the interface completely melt, thereby generating a polymer melt connection at the interface between the pipe fittings and the pipe to form a permanent connection. The pure plastic pipe fittings and the pipe are welded together, the welding effect is good, and the connection is convenient and reliable.
[0003] However, when using such a capacitor fused pipe fitting, a terminal block needs to be led out of the pipe fitting, and the terminal block is then connected to the power supply. In actual use, corrosion and water leakage often occur due to problems with the terminal block, and the power supply requirements are also relatively high. Utility Model Content
[0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a non-contact pipe connector that is heated by electromagnetic induction; the pipe connector is arranged with several circles of closed rings with magnetic conductivity and resistance. The metal closed rings generate eddy currents and heat under a certain magnetic field strength, and then use the heat to melt the pipe and the pipe body, thereby achieving a hot melt connection.
[0005] Specifically, a pipe connector includes a pipe body, a through hole of the pipe body serving as a pipe receiving area, and an induction ring surrounding the through hole is provided in the pipe body;
[0006] The induction ring is a closed ring with magnetic conductivity and resistance, which can generate current and heat under the magnetic field strength that varies within a specified range;
[0007] The pipe material and the pipe body are meltable when heated within a specified temperature range.
[0008] Optionally, a plurality of induction rings arranged along the axial direction are provided in the tube body.
[0009] Optionally, the induction ring is pre-embedded in the tube body.
[0010] Optionally, the distance between the induction ring and the outer diameter of the tube body is less than or equal to the distance between the induction ring and the outer diameter of the tube body.
[0011] Optionally, the pipe connector further includes a connecting pipe, and the through hole of the connecting pipe serves as a pipe accommodating area.
[0012] Optionally, an inwardly convex limiting portion is provided in the pipeline accommodating area.
[0013] The utility model has the following advantages:
[0014] This new design utilizes a non-contact heating method, pre-positioning the heating element within the pipe body and utilizing the principle of electromagnetic induction heating to melt the pipe body and the pipe material, thereby achieving an efficient and stable heat-melt connection. Compared to traditional electric fusion pipe connections, this connection method significantly avoids problems such as poor pipe connection and water leakage caused by lead-out wires, thereby improving the reliability and safety of the connection.
[0015] Furthermore, the induction ring design of this utility model is highly flexible and adaptable. The number of induction rings and inner diameter can be precisely adjusted based on the specific heat required for the pipe and pipe body during the heat-melt connection. Increasing the number of induction rings generates a correspondingly greater amount of heat, a feature that allows this utility model to easily connect pipes of varying specifications and materials, further broadening its application range and ensuring ideal connection results in a variety of working conditions.

[0027] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0028] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0029] As described in the background technology, pipes are generally connected by hot melting, and heat capacity is generally achieved through electric fusion fittings. The electric fusion fittings are a very important connection joint in plastic pipe connections, which firmly weld pipes in the same direction together. Most of the electric fusion sleeves in China are pure plastic injection-molded electric fusion fittings such as PE and PE-RT. The connection between the pure plastic electric fusion fittings and the pipes is heated by the electric heating wire arranged on the inner wall of the socket of the pure plastic electric fusion fittings. First, the pipes and fittings are heated to expand, and the air between the outer wall of the pipe and the inner wall of the fitting is removed. Then, the voltage supplied to the electric heating wire is increased to completely melt the resin at the interface, thereby generating a polymer melt connection at the interface between the pipe fittings and the pipe to form a permanent connection. The pure plastic pipe fittings and the pipes are welded together, the welding effect is good, and the connection is convenient and reliable.
[0030] However, when using such a capacitor fused pipe fitting, a terminal block needs to be led out from the pipe fitting, and the terminal block is then connected to the power supply. In actual use, corrosion and water leakage often occur due to problems with the terminal block. In addition, the power supply requirements are relatively high and the energy consumption is also high.
[0031] Because, in order to overcome the above shortcomings, this embodiment provides a pipe connector, such as Figures 1-4 As shown, the pipe connector includes a pipe body 100, the through hole of the pipe body is a pipe accommodating area, and an induction ring 300 surrounding the through hole is provided in the pipe body; preferably, the induction ring is pre-embedded in the pipe body;
[0032] The induction ring is a closed ring with magnetic conductivity and resistance (can be a metal ring, such as an iron ring), which can generate current and generate heat under a magnetic field strength that varies within a specified range;
[0033] The tube material 200 and the tube body 100 are meltable when heated within a specified temperature range.
[0034] like Figure 5 and Figure 7 As shown, when in use, two pipes that need to be hot-melt connected are placed in the pipe body, and then the pipe body is placed in a magnetic field environment with a set magnetic field strength. Since the induction ring is a closed loop and has magnetic conductivity and resistance, an induced current will be formed in a changing magnetic field environment. When the annular induction ring generates current, it will generate heat due to its resistance, thereby realizing the hot-melt connection between the pipe and the pipe body; compared with strip-shaped, plate-shaped or open conductors, the closed loop generates a larger current and thus generates more heat.
[0035] This technical feature utilizes a non-contact heating method, pre-positioning the heating element within the pipe body and utilizing electromagnetic induction heating to melt the pipe body and the pipe material, thereby achieving an efficient and stable heat-melt connection. Compared to traditional electric fusion pipe connections, this connection method significantly avoids problems such as poor pipe connection and water leakage caused by lead-out wires, thereby improving the reliability and safety of the connection.
[0036] To achieve heat-melt connections for pipes of varying specifications and materials, in one embodiment, several axially arranged induction rings are provided within the pipe. This technical feature utilizes the increased number of induction rings to generate more heat, making the present invention easily adaptable to pipe connection requirements of varying specifications and materials.
[0037] To better melt the pipe and achieve a better heat-melt connection, in one embodiment, the distance between the induction ring and the inner diameter of the pipe body is less than or equal to the distance between the induction ring and the outer diameter of the pipe body. This technical feature can achieve higher heat-melting efficiency between the pipe body and the pipe body, and better connection effect.
[0038] In another embodiment, Figure 8 and Figure 9 As shown, the pipe connector also includes a connecting pipe 400, the through hole of which serves as a pipe receiving area. During use, the pipes 200 at both ends are placed on the pipe body 100, and the pipe 200 with the pipe body 100 is then placed into the connecting pipe 400. Electromagnetic induction heating is then used to achieve a hot melt connection between the pipe body, the pipe, and the connecting pipe.
[0039] In order to better place the pipe with the pipe body into the connecting pipe, an inwardly convex limiting portion 401 is provided in the pipe accommodating area.
[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
