Plastic pipe connecting pipe fitting

Abstract

The invention discloses a plastic pipe connecting pipe fitting. The plastic pipe connecting pipe fitting comprises a pipe body, a burst and dead screwing prevention thread connecting end and a direct-inserted connecting end; the pipe body is in a right-angled bent form or horizontal; a two-layer step structured gear base is arranged in a thread connecting end of a pipe fitting body; the gear baseis projected on the inner wall of the pipe fitting body; a connecting body of the burst and dead screwing prevention thread connecting end is arranged on the inner wall of the pipe fitting body; a pipe inserting port is formed in the other end of the pipe fitting body; and a first sealing ring of the direct-inserted connecting end, a plastic clamping ring base and a stainless steel clamping ring are arranged in the inserting port. Through the mode, the plastic pipe connecting pipe fitting is simple in structure, adopts all plastic materials, is low in cost and convenient to install and disassemble, and adopts two pipe connecting modes: the first pipe connecting mode achieves the function of preventing the pipe burst and dead screwing phenomenon; and the second pipe connecting mode achievesthe direct inserting function capable of directly inserting a pipe in the pipe fitting without needing auxiliary tools and technicians.

Description

technical field [0001] The invention relates to building water supply and drainage pipeline technology, heating and ventilation pipeline technology and various industrial and agricultural production fields requiring pipeline connection, in particular to a plastic pipeline connection pipe fitting. Background technique [0002] Traditional pipeline connection pipe fittings need to have tools, auxiliary materials and technicians to complete the connection task during the pipeline connection construction. It also requires a power supply on the construction site to perform construction. The construction time is long and the working hours are high. The technology is highly dependent, and the construction quality largely depends on the technical level of the technicians. With the passage of time and the aging of materials, the joints after construction are prone to leakage at the joints.

[0002] Traditional pipeline connection pipe fittings require tools, auxiliary materials, and technicians to complete the connection task during pipeline connection construction. It also requires a power supply at the construction site to perform construction. The construction time is long and the working hours are high. The technology is highly dependent, and the construction quality largely depends on the technical level of the technicians. With the passage of time and the aging of materials, the joints after construction are prone to leakage at the joints. In addition, the traditional pipe connection fittings are basically All of them are for one-time use. After a fault occurs, they can only be destructively dismantled and cannot be reused, resulting in an increase in maintenance costs. When using metal threaded pipe fittings for connection, the metal pipe fittings are prone to burst when they are tightened too much, resulting in The pipe fittings are scrapped; or in the case of over tightening, the phenomenon of screwing occurs, which makes it difficult to disassemble after damage
