Abstract

The utility model belongs to a new tapered pipeline connector. At present, all pipeline connection in China adopts the joint installation such as straight through, T-bends, elbows, etc. of winch threads. Special tools such as pipe wrenches are needed during the installation, and pipes can only be installed when screws are twisted by screw wrenches. Repair consumes labor as well as time, which is troublesome. The utility model aims to design a connector which is formed by the connection of a tapered screw sleeve, a double-tapered nut and pipelines without twisted screws. The utility model has the advantages of simple structure, labor saving during installation and maintenance, convenient operation and use, little investment and low cost.

Description

Taper pipe joining apparatus

The utility model relates to a kind of conical pipeline electrical connector.

As everyone knows, the connection of pipeline is the very important constituent element of water supply and sewage in industrial and agricultural production and the daily life, and existing pipeline connection all is to adopt two ends or three end cars that the straight-through of screw arranged, elbow, threeway connects, all need special-purpose instrument during installation, pipe tongs, pipe strand screw wrench, after the screw thread silk has been twisted at the two ends of pipe earlier, straight-through with the good screw thread silk of car again, elbow, the threeway head, be connected, also must use the special pipes pincers during connection, just can be connected and fixed, add the steel pipe heaviness, the maintenance and installation of pipeline is time-consuming, and is very inconvenient.During as the mashed leakage of rust in the middle of a certain pipe, change this root pipe, also must twist screw thread in advance replacing pipe, sawed-off the pipe that original rust is mashed, could connect after having twisted screw, build in the thing at earth as if piping laying, just bother more during maintenance and installation.

The purpose of this utility model is to overcome above-mentioned deficiency to design a kind of new conical pipeline electrical connector, when pipe laying, need on water pipe, not twist screw, do not need special-purpose setting tool, only need two common spanners, can reduce working strength of workers greatly like this, improve tens times of work efficiency.

Below in conjunction with Figure of description the utility model is illustrated:

Fig. 1, be the utility model overall structure sectional view.

Fig. 2, be the utility model taper swivel nut sectional structure chart.

Fig. 3, be the utility model tapered cup nut shape and structure figure.

Fig. 4, be the utility model rubber washer structural drawing.

The utility model taper pipe joining apparatus is characterized in that as shown in Figure 1 it is formed a complete set of and formed by left pipeline (1), left tapered cup nut (2), taper swivel nut (3), rubber washer (4), right tapered cup nut (5), right pipeline (6). Be about to taper swivel nut (3) Connector fixes, set up respectively left and right sides tapered cup nut (2), (5) at the two ends of taper swivel nut (3), in the middle of tapered cup nut (2), (5), pass respectively for hollow round, left and right pipeline (1), (6) in the middle of tapered cup nut (2), (5), be fixed in the middle of the horn socket (3). Taper swivel nut (3) tapered cup nut specification size designs according to duct size. Rubber washer (4) is circle hollow shape (as shown in Figure 4), respectively two rubber washers (4) is placed the centre of horn socket (3) and left and right sides pipeline (1), (6), with compress rubber packing ring behind the conical nut fastening, prevents the connector immersion. Can also make the assembling pipe joints such as threeway connector, elbow according to principle of the present utility model, pipeline need not twist silk thread mouth during installation.

Taper pipe joining apparatus of the present utility model has simple in structure, and installation and maintenance save labor; Easy to use, small investment, cost is low, high efficiency.

Claims

1, a kind of conical pipeline connector, its feature: it is by left pipeline (1), left tapered cup nut (2), taper swivel nut (3), form a complete set of and form as leather washer (4), right tapered cup nut (5), right pipeline (6): be about to taper swivel nut (3) connecting head that fixes, set up left and right sides tapered cup nut (2), (5) respectively at the two ends of taper swivel nut (3), the centre of tapered cup nut (2), (5) is the open circles shape, left and right sides pipeline (1), (6) are passed in the middle of tapered cup nut (2), (5) respectively, are fixed in the middle of the horn socket (3).

2, conical pipeline connector according to claim 1, its feature: be provided with two picture leather washers (4) in middle the joint of horn socket (3) and left and right sides pipeline (1), (6) fixing tight with tapered cup nut, prevents that connector from soaking.
