Abstract
A nonmetal inset used for a pipe fitting for water supply and drainage comprises a pipe fitting body, wherein annular falling-off prevention grooves are formed in the outer side wall of the upper portion of the pipe fitting body in the circumferential direction, tooth-shaped structures are arranged on the upper end portion of the pipe fitting body, plastic base material filling is arranged in a cavity in the upper portion of the pipe fitting body, a through hole is formed in the plastic base material filling, and the through hole is coaxial with the pipe fitting body and communicated with a cavity in the lower portion of the pipe fitting body. A thread is arranged on the outer side wall of the lower portion of the pipe fitting body. The upper end of the pipe fitting body is embedded in a connecting piece through the injection molding technology, and the connecting piece is formed by a plastic base material. The annular falling-off prevention grooves and the tooth-shaped structures are all located in the connecting piece, wherein a through hole is formed in the connecting piece, and the plastic base material filling is formed in the lower portion of the inner side of the connecting piece. The annular falling-off prevention grooves and the tooth-shaped structures can be respectively used for preventing the pipe fitting body from rotating relative to the connecting piece when the pipe fitting body is subjected to tensile force and torque during the installation of the pipe fitting body. The plastic base material filling is located between a water way and the pipe fitting body, pressure in the water way extrudes the plastic base material filling, and therefore leakage from the connecting position of the plastic base material filling and the pipe fitting body is prevented. The thread at the lower end of the pipe fitting body can meet the requirements of conventional mechanical properties.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to water tubular union, particularly a kind of non-metallic insert for the plumbing pipe fitting.
Background technique:
In prior art, in order to realize the connection between water pipe, usually need to adopt water tubular union, generally include an inserts in water tubular union, this inserts is embedded in plastic rubber substrate by Shooting Technique.Because frictional force between inserts and plastic rubber substrate is large not, in use can cause inserts and plastic rubber substrate to relatively rotate, affect the connection of pipe fitting, also make the easy seepage of pipeline; Particularly when the thermal conductivity of inserts and plastic rubber substrate is unequal (such as adopting the low non-metallic insert of thermal conductivity), cause because expanding with heat and contract with cold and the pipe fitting plastic rubber substrate between the gap larger, make the poorly sealed of pipeline joint, cause leakage problems.
Summary of the invention:
The purpose of this utility model is to provide a kind of non-metallic insert for the plumbing pipe fitting, and described this non-metallic insert for the plumbing pipe fitting will solve prior art because combination force between inserts and plastic rubber substrate causes inserts to rotate, cause the technical problem of pipeline leakage relative to plastic rubber substrate not greatly.
This non-metallic insert for the plumbing pipe fitting of the present utility model, comprise a pipe fitting, wherein, along the circumferential direction be provided with annular anticreep groove in the upper outside wall of described pipe fitting, the end, upper end of pipe fitting is provided with tooth-shape structure, be provided with the plastic rubber substrate packing in the tube chamber on pipe fitting top, be provided with through hole in described plastic rubber substrate packing, described through hole is coaxial with pipe fitting and be communicated with the tube chamber of pipe fitting bottom.
Further, be provided with screw thread on the outer side wall of the bottom of pipe fitting.
Further, be provided with the seal ring standing groove in the outer side wall on pipe fitting top, be provided with seal ring in the seal ring standing groove.
Further, described tooth-shape structure comprises 8 teeth, and these 8 teeth distribute along even circumferential at the end face of pipe fitting upper end.
Working principle of the present utility model is: the upper end of pipe fitting is embedded in the link of a plastic rubber substrate formation by Shooting Technique, annular anticreep groove and tooth-shape structure all are positioned at link, be provided with through hole in link, the link lower inside forms described plastic rubber substrate packing.Annular anticreep groove and tooth-shape structure can prevent respectively pipe fitting when mounted when under tension and moment of torsion, the link that forms with plastic rubber substrate rotates.The plastic rubber substrate packing is between water route and pipe fitting, and pressure extrusion plastic rubber substrate during use in the water route has solved water from the problem of plastic rubber substrate and pipe fitting joint seepage.The screw thread of pipe fitting lower end can satisfy conventional mechanical property requirement.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges anticreep groove and tooth-shape structure in top and the upper end of non-metallic insert, can prevent effectively that inserts from rotating relative to the link that plastic rubber substrate forms when being subject to moment, guarantees the sealing between the link of inserts and plastic rubber substrate formation.
