Abstract

The utility model discloses a PC pipe welding connector, which relates to the technical field of PC pipes and aims to improve the existing welding means.

Description

PC pipe welding connector

Technical Field

The utility model relates to the technical field of PC pipes, in particular to a PC pipe welding connector

Background

The PC pipe is a polycarbonate pipe, is a common transparent plastic pipe, can be provided with color, and has wide application fields. For connection of PC pipes, a quick-release hose connector is usually adopted in the prior art for connection, or the quick-release hose connector is sleeved on a copper pipe connector, and a clamp connection is matched. Wherein, quick detach hose connection spare can not bear the high pressure, and the scheme among the prior art all can introduce too much structure, increase volume and weight. Hot-melt welding is an ideal connecting means, but one of the common welding methods is to use flame heating to melt pipelines and then butt-weld the pipelines, and the method has high requirements on experience and technical methods of operators and cannot guarantee the qualification rate under long-term operation. The other is to use a heating plate to heat two butted pipe end faces to a molten state and then butt the two butted pipe end faces, and the method needs to cut the end faces of the pipe in advance to enable the two end faces to be tightly screwed, and the end faces are required to be calibrated and wiped after cutting, so that the time and the labor are wasted, and special cutting equipment is needed.

In view of the foregoing, there is still room for improvement in the manner of welding, and the present application is directed to providing a new welding connector for improving the existing welding means.

Disclosure of Invention

The utility model provides a PC pipe welding connector which comprises a tubular hard inner pipe and a tubular soft outer pipe, wherein the soft outer pipe is sleeved on the hard inner pipe, and a metal ring is arranged in the soft outer pipe.

The utility model is further provided with: and limiting flanges for blocking the soft outer tube are arranged at two ends of the hard outer tube.

The utility model is further provided with: the melting point of the hard inner tube is higher than that of the soft outer tube.

The utility model is further provided with: the cross section of the metal ring is rectangular.

The beneficial effects of the utility model are as follows:

1. the operation is simple, and no excessive dependence is caused on experience and manipulation, because when the metal generates eddy current to generate heat by using the electromagnetic, only the heating time is required to be controlled;

2. no extra processing process and complicated welding steps are adopted, so that the method is efficient and time-saving.

Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

Referring to fig. 1-3, the utility model provides a welding connector for a PC tube, which comprises a tubular hard inner tube 1 and a tubular soft outer tube 2, wherein the soft outer tube 2 is sleeved on the hard inner tube 1. The melting point of the hard inner tube 1 is higher than that of the soft outer tube 2. Wherein the material of the soft outer tube 2 is PC, and the melting point of the soft outer tube is 230 ℃; the material of the hard inner tube 1 is polytetrafluoroethylene, and the melting point of the hard inner tube is 320 ℃. Both ends of the hard outer tube are provided with limit flanges 11 for blocking the soft outer tube 2, but the diameter of the flanges is smaller than the outer diameter of the soft outer tube 2. The soft outer tube 2 is internally provided with a pre-buried metal ring 21, and the cross section of the metal ring 21 is rectangular.

When in use, the outer diameter of the flexible outer tube 2 in this solution is required to be consistent with the inner diameters of the two PC tubes to be welded. The specific use process is as follows: two ends of the PC pipe welding connecting piece in the scheme are respectively inserted into two PC pipes to be welded, and the hard inner pipe 1 plays a supporting role in the process. Then, the metal ring 21 is heated by using an electromagnetic coil until the soft outer tube 2 is in a molten state, the soft outer tube 2 plays a role of welding flux, and the soft outer tube 2 is connected with two PC tubes to be welded into a whole after being melted, and then is subjected to stationary cooling. Since the melting point of the hard inner tube 1 is higher, it is not affected. The rectangular cross section metal ring 21 increases the melting area of the soft outer tube 2, making the welding more fully secure.

The advantage of this scheme is: 1. the operation is simple, and no excessive dependence is caused on experience and manipulation, because when the metal generates eddy current to generate heat by using the electromagnetic, only the heating time is required to be controlled;
