Abstract
The utility model discloses a straight-through joint for pipe fittings. One barb-type interface and one horn-type interface are arranged at the two ends of a joint body respectively; and grooves are formed on the outer wall of the horn-type interface along the periphery thereof. The utility model is made of polyethylene, and has the advantages of good flexibility and back elasticity, long service life, ageing resistance, dismountability and reusability, as well as high connection simplicity and safety leak tightness.
Description
Technical field
The utility model belongs to the pipe fitting connected element, particularly a kind of fitting to fitting joint.
Background technique
At present, in the synthetic resin of China, polyethylene becomes one of kind with the fastest developing speed with its good performance.Especially over past 10 years, the PE pipe is annual to rise with 10%-15% speed, and the consumption of PE pipe has surpassed pvc pipe.Although in continuous increase, being used to connect PE fitting pipe spare and technology, the consumption of tubing can not satisfy growth requirement.And have installing/dismounting inconvenience, and sealing, wear resistance, impact resistance are poor, and the run, drip, leak phenomenon is more serious.For inferior, need the special-purpose switching performance of development PE pipe good, the direct joint of being convenient to install.
Summary of the invention
The purpose of this utility model provides and a kind ofly provides special-purpose for connecting the PE pipe, and is easy to use, switching performance good, the fitting to fitting joint of resistance to compression, anti-intensity.
For achieving the above object, solution of the present utility model is: a kind of fitting to fitting joint, the two ends of its joint body are respectively equipped with two interfaces, and a described end interface is a hangnail type interface, the other end interface is the horn shape interface, one week of outer wall periphery is provided with groove along the horn shape interface.
The utility model is to be material with polyethylene, has good flexibility and returns former elasticity, and long service life, anti-aging, can repeated removal use, have very strong connection simplicity and security seal.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
As shown in Figure 1, this fitting to fitting joint, the two ends of its joint body are respectively equipped with two interfaces, a described end interface is a hangnail type interface 1, the other end interface is a horn shape interface 2, along horn shape interface 2 one week of outer wall periphery be provided with groove, described groove can be provided with 8 roads.When the PE pipe was inserted on the hangnail type interface 1, hangnail type interface 1 is the inwall of contact PE pipe closely, utilized the strong friction of hangnail type interface 1, and tube wall is fixedly secured.When the PE pipe is inserted on horn shape interface 2, can play fixedly tube wall effect along 8 road tongues on the horn shape interface 2, when increasing, intraductal pressure can effectively alleviate the fatigability of tube wall, and no run, drip, leak phenomenon takes place.Of the present utility model current or gas by the time, the inner nosepiece wall smoother smoothly links to each other with tube wall, can be unblocked.
Claims (1)
1. fitting to fitting joint, the two ends of its joint body are respectively equipped with two interfaces, it is characterized in that: a described end interface is a hangnail type interface (1), and the other end interface is horn shape interface (2), one week of outer wall periphery is provided with groove along horn shape interface (2).
