Abstract
The utility model relates to a novel thread joint of a plastic-steel pipe. The novel thread joint of the plastic-steel pipe includes a pipe body, and is characterized in that a plastic tube is lined on the inner wall of the pipe body; and the outer wall of the pipe body is divided into three parts, including a middle section, as well as first screw threads and second screw threads which are symmetrically distributed along the middle section. Compared with the prior art, the novel thread joint of the plastic-steel pipe has the following advantages: the connection is firm, and the inner wall of the pipe body is avoided from rustiness through arranging the plastic tube on the inner wall of the pipe body.
Description
Technical field
The utility model relates to a kind of new steel and moulds pipe to the wire connection head, is mainly used in being connected of pipeline and water valve.
Background technique
The liner that the inwall of existing joint has no, after long-term the use, the inwall of pipeline gets rusty easily, and the water source is caused certain pollution; The cross section of screw thread appears cylindrical, exists to connect unstable hidden danger.
Summary of the invention
For overcoming the defective of existing technology, the utility model provides a kind of and is connected firmly, and the new steel that can not get rusty is moulded pipe to the wire connection head.The technological scheme of the utility model is: a kind of new steel is moulded pipe to the wire connection head; Comprise body; It is characterized in that: the inwall at said body is lined with plastic tube, and the outer wall of said body is divided into three parts, first screw thread and second screw thread that are respectively intermediate section and are symmetrically distributed along intermediate section.
The cross section of described first screw thread and second screw thread is trapezoidal, dwindles gradually to the end of intermediate section to body.
The end of described body is provided with the sanding of flat mouth.
The utility model compared with prior art has following advantage: be connected firmly, and because the problem that inboard wall of tube body gets rusty has been stopped in the existence of inboard wall of tube body plastic tube.
Description of drawings
Fig. 1 is the agent structure schematic representation of the utility model;
Fig. 2 is the sectional view of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2; The utility model relates to a kind of new steel and moulds pipe to the wire connection head, comprises body 1, is lined with plastic tube 6 at the inwall of said body 1; The outer wall of said body 1 is divided into three parts, first screw thread 3 and second screw thread 4 that are respectively intermediate section 2 and are symmetrically distributed along intermediate section 2.
The cross section of described first screw thread 3 and second screw thread 4 is trapezoidal, dwindles gradually to the end of intermediate section 2 to body 1, and the end of described body 1 is provided with sanding of flat mouth 5.
The utility model in use; One end (first screw thread or second screw thread) is connected with any pipeline that matches or valve; The other end (second screw thread or first screw thread) is connected with valve or pipeline; Realize docking of pipeline and pipeline or pipeline and valve,, increased soundness owing to first screw thread and second cross section all is trapezoidal.
Claims (3)
1. a new steel is moulded pipe to the wire connection head, comprises body, and it is characterized in that: the inwall at said body is lined with plastic tube, and the outer wall of said body is divided into three parts, first screw thread and second screw thread that are respectively intermediate section and are symmetrically distributed along intermediate section.
2. new steel according to claim 1 is moulded pipe to the wire connection head, it is characterized in that: the cross section of described first screw thread and second screw thread is trapezoidal, dwindles gradually to the end of intermediate section to body.
