Detailed Description
Referring to fig. 3, a composite reinforced plastic pipe connection structure with butt-weldable ends comprises: the pipe comprises a pipe body 1 and a joint connector 3, wherein the end part of the pipe wall of the pipe body 1 is provided with a connecting section 2, the connecting section 2 tilts and tilts from the inside to the outside, the joint connector 3 is fixed at the end part of the pipe body 1 through an injection molding process, and the joint connector 3 completely covers the connecting section 2 at the end part of the pipe body 1 during injection molding, so that a pipe with a welded joint is formed.
The joint connector 3 is formed in a circular ring shape because it is injection-molded along the end pipe wall. The injection-molded joint connector 3 completely covers the connecting section 2, and also partially covers the outer wall of the pipe body 1 to form a stable joint structure.
The size of the inner diameter of the circular ring shape of the joint is equal to that of the inner diameter of the pipe body 1, the cross section area of a fluid channel in the pipe body 1 cannot be changed after the joint connector 3 is additionally arranged to form the joint, and the flow speed is not influenced.
The section of the connecting section 2 is in a strip shape and is a part formed by flaring the end part of the tube body 1, and the whole connecting section 2 is in a cone shape and is similar to a bell mouth in shape.
The preparation method of the composite reinforced plastic pipe connecting structure with the end capable of being butt-welded comprises the following steps:
1. the end of the tube is first heated, see fig. 1.
2. Then, the heated end pipe is straightened and flared, and the inlet end becomes a bell mouth (slightly tilted), as shown in fig. 2.
3. And maintaining the injection molding pressure or the extrusion pressure, and cooling and shaping.
4. And (4) loosening the movable die, withdrawing the pipe or extracting the die core, and forming the pipe, referring to fig. 3.
Referring to fig. 4, two pipes with welded joints can be connected by means of a welded joint connector 3, the injection molding material of the joint connector 3 is preferably polypropylene, and plastic welding is a connection method that the contact surfaces of two plastic parts are fused at the same time by a heating method so that the two plastic parts are combined into a whole.
