Description

An Improved Pipe Fitting Connecting Device

technical field

The utility model relates to pipe fittings, in particular to an improved pipe fitting connecting device, which is suitable for one-dimensional, two-dimensional and three-dimensional connections between pipes.

Background technique

Pipe fittings are parts that connect pipes into pipelines. According to the connection method, they can be divided into four types: socket fittings, threaded fittings, flanged fittings and welded fittings. They are mostly made of the same material as the pipes. Existing pipe fittings connection devices include elbows (elbows), flanges, tees, crosses (crossheads) and reducers (big and small heads). Elbows are used where pipes turn; flanges are used to connect pipes and pipes to each other, and are connected to pipe ends; tee pipes are used where three pipes gather; four-way pipes are used where four pipes gather; Diameter pipes are used where two pipes of different diameters are connected.

The existing pipe fitting connecting device has a simple structure and is easy to assemble, but its connection with the pipe has a single structure and poor sealing performance. During use, leakage and falling off will occur, resulting in frequent replacement of the pipe fitting connecting device. In addition, its own mechanical strength is slightly insufficient, thereby affecting its own service life, and also reducing the stability, reliability and safety of the pipe fitting connection device.

Utility model content

The purpose of this utility model is to improve the existing pipe fitting connecting device for the above-mentioned shortcomings, and provide a pipe fitting connecting device with tight connection, high mechanical strength, stability, reliability and safety.

The technical scheme that realizes the utility model purpose is:

An improved connection device for pipe fittings, which includes a first pipe fitting body, which is different from the prior art in that it also includes a structure that is the same as that of the first pipe fitting body, is arranged inside the first pipe fitting body, and protrudes outside the first pipe fitting body 10 - a 14 cm second pipe fitting body, on the outer wall of the opening end of the second pipe fitting body, convex ribs and/or material storage grooves for placing adhesive are equidistantly arranged.

The second pipe body is closely fixed to the first pipe body.

The number of the ribs and/or storage grooves is an even number.

The length of the rib is 4-6 cm, and the height is 2-4 cm.

The length of the storage groove is 4-6 cm, the depth of the groove is 2-4 cm, and the adhesive is placed in the storage groove.

The first pipe fitting body and the second pipe fitting body include a one-way pipe (straight-through pipe), a three-way pipe (T-shaped pipe), a four-way pipe (cross-shaped pipe), a six-way pipe, an L-shaped pipe, a K-shaped pipe, a double V-shaped pipes and reducers, etc.

When the second pipe fitting body is a through pipe (straight through pipe), along the positive and negative directions of its coordinate axis, convex ribs and/or storage grooves for placing adhesive are equidistantly arranged on the outer wall of its open end.

When the second pipe fitting body is a tee pipe (T-shaped pipe), in its plane coordinate system, along the negative direction of the Y-axis and the positive and negative direction of the X-axis, convex ribs and/or are equidistantly arranged on the outer wall of the opening end Storage groove for adhesive.

When the second pipe fitting body is an L-shaped pipe, in its plane coordinate system, along the positive direction of the Y-axis and the positive direction of the X-axis, the outer wall of the opening end is equidistantly provided with ribs and/or placed on the surface of the adhesive. Storage groove.

When the second pipe fitting body is a cross-shaped pipe, in its plane coordinate system, along the positive and negative directions of the Y axis and the positive and negative directions of the X axis, convex ribs and/or bonding are arranged equidistantly on the outer wall of its opening end. agent storage tank.

The pipe fitting connecting device of the utility model adopts a pipe fitting connecting device with convex ribs for disassembly when it is not necessary to be connected to the connected pipe for a long time; Pipe fitting connection device, or use a pipe fitting connection device with ribs and material storage grooves, and place adhesive in the material storage groove to make the connection of the pipes more secure.

The pipe fitting connecting device of the utility model is to arrange a second pipe fitting body with the same structure in the traditional first pipe fitting body, and set ribs and/or material storage grooves at the opening end of the second pipe fitting body, so that the connected pipes The connection with the first pipe body is tighter and difficult to slip, and the mechanical strength of the traditional first pipe body itself is increased and the mechanical strength of the joint is improved.

The pipe fitting connecting device of the utility model has high mechanical strength, long service life, stable connection, high airtightness, safety, reliability and versatility, is suitable for different bonding processes, and can be used for various materials. Connection of tubular members. It can be widely used in pipeline connection of water, oil, gas, electric power and communication.
