Abstract

The utility model relates to a low pressure steam pipeline connecting piece. An inward salient edge is arranged on a connector body of the low pressure steam pipeline connecting piece at the point where the connector body is sheathed with a port at one end of the pipe. The inward salient is clamped by a clamping spring which is embedded in a ring groove of the end of the pipe. Inner threads of the other end of the connector body are matched with outer threads of a pipe connecting piece. The sealing ring is arranged between the port of the pipe and a port of the pipe connecting piece. The utility model omits a sheathing wire for the end of the pipe and heavy tools. The utility model has the advantages of simple structure, convenient operation, convenient maintenance, time saving, labor saving, simple processing technology and low cost.

Description

Low-pressure water steam pipe pipe connecting

The utility model relates to a kind of low-pressure water steam pipe pipe connecting.

Existing low-pressure water, steam pipe road are in the construction and installation process, and the amount of labour mainly spends in the threading of pipe coupling, the outfit heaviness, and labor intensity is big, and work efficiency is low, operator's technical merit is required high; To on interface tube, be coated with lead oil during installation, add flax silk or twine raw meal belt, complex operation, the interface easy to leak, and easily pollute steam in the pipe; Pipe joint generally will be used the malleable cast iron material, the processing technology complexity, and required cutter is many, thereby cost is higher; Change, when repairing, need pull down many relevant pipe fittings when an interface seepage, keep in repair very inconvenient.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provide a kind of and save time, laborsaving, material-saving, operation, maintenance are easy, processing is simple, the low-pressure water steam pipe pipe connecting that cost is low.

The purpose of this utility model can reach by following measure:

A kind of low-pressure water steam pipe pipe connecting comprises fittings body 2 and seal ring 7, and its special way is that it also comprises in the annular groove 9 that is embedded in pipe 6 ports, and is protruding in the jump ring 4 on pipe 6 surfaces; The port that described fittings body 2 is placed in pipe 6 terminations one end is provided with interior convex edge 1, convex edge 1 is stuck on the jump ring 4 in described, the other end of described fittings body 2 is provided with the internal thread 3 that cooperates with the outside thread of pipe connector 8 terminations, and described seal ring 7 is located between the port of pipe 6 and pipe connector 8.

The interior convex edge 1 of the utility model fittings body 2 ports can be cyclic convex edge or is distributed in the dentation convex edge on port week edge.

Jump ring 4 of the present utility model is one to be provided with the annulus of opening 5.

The accompanying drawing drawing is described as follows:

Fig. 1 is the structural representation of the utility model fittings body.

Fig. 2 is the structural representation of the utility model jump ring.

Fig. 3 is an assembling schematic representation of the present utility model.

Fig. 4 is the structural representation of the pipe that joins with the utility model.

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1, an end of the utility model fittings body 2 is provided with internal thread 3, and the other end port is provided with interior convex edge 1, and interior convex edge 1 can be cyclic convex edge, also is distributed in the dentation convex edge of fittings body 2 ports.Jump ring 4 of the present utility model is the annulus with an opening 5, sees Fig. 2.Referring to Fig. 3, during installation, an end of convex edge 1 is placed in the termination of pipe 6 in earlier fittings body 2 being provided with, jump ring 4 is stuck in the annular groove 9 of pipe 6, the termination is provided with the structure of the pipe 6 of annular groove 9, sees Fig. 4, jump ring 4 is protruding in pipe 6 surfaces, can block the interior convex edge 1 of fittings body 2 ports, make fittings body 2 be placed on the pipe 6 relative limit, not slippage.Annular seal ring 7 is put into pipe 6 ports of fittings body 2, place fittings body 2 to be provided with in the port of internal thread 3 one ends with being provided with externally threaded pipe connector 8, tighten fittings body 2 with pipe wrench, then pipe connector 8 ports are pressed in pipe 6 ports with seal ring 7, and pipe connector 8 and pipe 6 are sealed and matched.Fittings body 2 of the present utility model is good to adopt the 10# steel; Jump ring 4 can adopt the carbon steel silk, and seal ring 7 can adopt sheet materials such as rubber, asbestos.

The utility model compared with prior art has following advantage:

1, saved pipe head mantle fiber and heavy tapping tool, instrument is light, and it is strong to greatly reduce work Degree improves work efficiency more than two times, requires low to operating personnel's technical merit.

2, saved and be coated with lead oil on the interface tube, add flax silk or twine raw material band, with rubber blanket or asbestos pad sealing, Sealing joint is reliable, and is non-leakage, construction cleaning, easy, can not cause lead oil in construction and in using to water, The pollution of vapour.

3, processing technology is easy, can save a large amount of man-hours and process tool, only adopts casting pig to reduce Cost is more than 30%.

4, easy to maintenance, when dismounting, mounting interface, need not to pull down relevant pipe fitting.
