Abstract

The utility model discloses a press fitting pipe elbow which is mainly composed of the following components: an internal thread connection pipe opening, a press fitting connection pipe opening, pipe wall outer teeth, a bottom blocking shoulder, etc. The internal thread connection pipe opening and the press fitting connection pipe opening are mounted through a 90 DEG bend angle therebetween. An inner circumferential surface of the internal thread connection pipe opening is provided with screw threads. Furthermore an outer pipe wall of the internal thread connection pipe opening is provided with six pipe plier stress surfaces. The press fitting connection pipe opening is provided with three pipe wall outer teeth. A groove for placing a rubber sealing ring is provided between every two pipe wall outer teeth. An inner end of the pressing fitting connection pipe opening is provided with a bottom blocking shoulder.

Description

A kind of clamp-press type pipe elbow

(1) technical field

The utility model relates to the pipe connecting device in the plastic-aluminum combined pipeline, is specifically related to a kind of pipe elbow of clamp-press type.

(2) background technique

Along with the employed occasion of pipeline etc. becomes increasingly complex, and under the overall situation that people's living standard is constantly improved, the requirement of common pipeline union piece is also constantly being improved.Plastic-aluminum combined pipeline system integrates metal, nonmetal pipeline advantage, have environmental protection and energy saving, light rigidity, bent bullet and do not have many advantages such as leak source socket joint connection, the generally approval and the high praise in market have been obtained, this series products is specially adapted to all kinds of water supply piping systems of high level, superelevation layer and modern industry factory building, so market prospects are extremely wide.Pipe elbow is one of a kind of part the most commonly used in the pipeline class accessory product, because the occasion more complicated that some pipelines are installed, therefore on the usability of pipe elbow, need possess fastness and characteristics such as easy are installed, and common pipe elbow is connected with the pipe thread end owing to depending mouth of pipe internal thread alone, and therefore defectives such as sliding tooth of screw thread and internal thread tube wall break easily take place when as installed.

(3) summary of the invention

The utility model provides a kind of and has been connected the combined clamp-press type pipe elbow of the mouth of pipe with clamp-press type by the internal thread connection mouth of pipe at the defective that common pipe elbow exists on fastness and property easy for installation, and main technical schemes is as follows:

A kind of clamp-press type pipe elbow, mainly connecting the mouth of pipe, the clamp-press type connection mouth of pipe, tube wall external tooth, bottom shoulder block etc. by internal thread forms, the internal thread connection mouth of pipe is connected the mouth of pipe and is 90 ° of bent angle settings with clamp-press type, the inner headed face that internal thread connects the mouth of pipe is provided with screw thread, and is provided with six pipe wrench stress surfaces on the outer tube wall of the internal thread connection mouth of pipe.Be provided with three road tube wall external tooths on the clamp-press type connection mouth of pipe, be provided with the groove of placing rubber seal ring between per two road tube wall external tooths, the inside end that connects the mouth of pipe at clamp-press type is provided with the bottom shoulder block.

Clamp-press type pipe elbow described in the utility model, the connection mouth of pipe of clamp-press type design can use special-purpose Press Plier earlier the supporting stainless steel sleeve compression of pipe when mounted, Deng pipe be inserted in connect the mouth of pipe after, the two road rubber seal rings of placing on can making pipe and being connected the mouth of pipe are combined closely, reach the double action of the tight-lipped solid and sealing of pipe and connecting tube, have advantages such as simple in structure, good airproof performance, saving material.
