Description

Pipe connector

One, technical field

The utility model relates to a kind of pipe connector.

Two, background technique

Pipe connector is the spare part in common that pipeline connects, and traditional pipe connector is the loose joint that two ends have screw thread, and it mainly acts on is exactly connecting line.And in real work, some pipelines are often arranged because of leak source occurring than the living corrosion of long hair service time, as heating installation or oil, gas, water pipeline, in case leak source appears in pipeline, leak stopping had been not only nervous, but also trouble.Especially the maintenance of the heating installation pipeline in winter is cut off heating installation earlier during construction, and the water in the blow-down pipe prescinds the pipeline that an end has leak source, then welding.Because most of heating installation pipelines are positioned at corner or nearer from wall, the space is narrow, does not see the weld bond position, and soldering appliance is put to good use not open, and welding is difficulty very, time-consuming, effort, and be difficult to guarantee welding quality again.

Three, summary of the invention

Goal of the invention of the present utility model is to provide a kind of pipe connector at the problems referred to above, solves the problem that the pipeline leak stopping connects easily and efficiently.

The technological scheme that above-mentioned purpose adopted is: this pipe connector is made of housing, pressure cap, hold-down ring, seal ring, spacer sleeve, interior hoop; There is through hole at the center of pressure cap, hold-down ring, seal ring, spacer sleeve, interior hoop; Hold-down ring, seal ring, spacer sleeve are two groups and are contained in the housing with interior hoop that interior hoop is positioned at the centre of two groups of seal rings, and pressure cap is threaded with housing.

Adopt the good effect of technique scheme: the utility model is by housing, pressure cap, hold-down ring, spacer sleeve, interior hoop the extrusion expansion of seal ring to be out of shape connection and the sealing that realizes pipeline, is applicable to the connection and the maintenance of the various pipelines of water, oil, gas; Too near in particular for the leak source pipeline that can not make electricity consumption, gas welding or leak source pipeline present position by the corner, do not see weld bond during welding, the pipeline maintainance of inconvenient operation, not only convenient but also quick, save time, laborsaving, effective.
