Abstract

A fast-assembly pipe connector is characterized in that two pipe fittings with wedged teeth at outside diameters, two semicircular engage switches, an engage switch outer ring with taper at the inside diameter, and fastening bolts; the pipe fittings with wedged teeth at the outside diameters are arranged on the same axis with a pipeline; the two semicircular engage switches cover the wedged teeth of the pipe fittings; the engage switch outer ring is sleeved outside the two semicircular engage switches smoothly; and the tail end of the engage switch outer ring is fixed via pins. Compared with flange and other conventional connections, the utility model has the characteristics of compact external structure, light weight, small installation space, simple and fast installation, no screw thread and bolt, no requirement of using a wrench, measuring the moment or aligning a bolt hole, fast connection and disassembly during the whole connection process, good leak tightness, high thermal stability, high reliability and the like. As the pressure in a pipe increases, the leak tightness is enhanced, so that leakage can not be caused; and matching obstacle and seal obstacle between metal are avoided.

Description

The fast-assembling pipe jointer

Technical field

The utility model belongs to the pipe jointer field, particularly a kind of fast-assembling pipe jointer.

Background technique

In industries such as oil, chemical industry, electric power, pipeline is the important structure and the constituent element of equipment and equipment, and the connection of various sizes pipeline is to guarantee that pipeline connects and unimpeded critical component.Pipe connecting method commonly used is that flange connects, and this method connects that external diameter is big, weight is also big, it is big to take up room, and especially under the parallel occasion of many pipelines, the joint big situation that takes up room is particularly outstanding.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of fast-assembling pipe jointer, has characteristics such as the installing space of taking is few, installation is simply quick.

A kind of fast-assembling pipe jointer of the utility model, it is characterized in that comprising that two pipe joints of external diameter band chisel teeth, semicircle gearing device, internal diameter have the gearing device outer shroud and the fastening screw trip bolt of tapering, external diameter has the pipe joint of chisel teeth and piping erection on same axis, two semicircle gearing devices cover outside the chisel teeth of pipe joint, the outside that is enclosed within two semicircle gearing devices that the gearing device outer shroud is level and smooth, with pin that the gearing device outer shroud is terminal fixing.

Working principle of the present utility model is: two pipe joints that design is unique, external diameters have chisel teeth and piping erection on same axis, are covered outside the chisel teeth of joint with two semicircle gearing devices then.Chisel teeth is when laterally locking pipe joint, and also providing longitudinally, pressure compresses O RunddichtringO (between two pipe joints).Behind the semicircle gearing device locking pipe joint, have the level and smooth outside that is enclosed within semicircle gearing device of gearing device outer shroud of tapering again with an internal diameter, force two gearing devices closely to link to each other.With pin that the taper outer shroud of gearing device is terminal fixing at last, make attachment security reliable.

Advantage of the present utility model:

Be connected with routines such as flanges and compare, this connector have the form structure compactness small and exquisite, in light weight, take installing space few, characteristics such as simple quick are installed, its length, external diameter reduce 30%～50%, weight reduces to 50%～80%, especially when being connected, can also effectively improve the flow distribution in the reactor, reduce taking up room with reactor.The 2nd, this joint structure is simple, and assembly and disassembly is quick, and is easy to maintenance.Compare with flange, the pipe coupling number of components and parts has reduced over half, and no screw thread, bolt need not spanner, need not measure moment, need not aim at bolt hole, and whole connection procedure can be realized connecting fast and dismounting.The 3rd, good airproof performance, thermostability height.With the increase of pipe internal pressure, sealing also constantly strengthens, and can not produce leakage.And under the situation that pipeline inside and outside rapid heat cycle replaces, still can keep good thermostability.The 4th, the reliability height does not exist to cooperate obstacle or intermetallic seal drag.

Among the figure: 1 pipe joint, 2 semicircle gearing device 3 gearing device outer shrouds 4 seal rings 5 fastening screw trip bolts

Embodiment

As shown in Figure 1, the fast-assembling pipe jointer, comprise that two pipe joints 1 of external diameter band chisel teeth, two semicircle gearing devices 2, internal diameters have the gearing device outer shroud 3 and the fastening screw trip bolt 5 of tapering, two pipe joints that design is unique, external diameters have chisel teeth 1 and piping erection on same axis, are covered outside the chisel teeth of pipe joint 1 with two semicircle gearing devices 2 then.Chisel teeth is in horizontal lock-on connection, and also providing longitudinally, pressure compresses O RunddichtringO 4 (between two pipe joints).Behind the semicircle gearing device 2 locking pipe joints 1, have the level and smooth outside that is enclosed within semicircle gearing device 2 of gearing device outer shroud 3 of tapering again with internal diameter, force two gearing devices closely to link to each other.With fastening screw trip bolt 5 that gearing device outer shroud 3 is terminal fixing at last, make attachment security reliable.

Claims

1. fast-assembling pipe jointer, it is characterized in that comprising that two pipe joints of external diameter band chisel teeth, semicircle gearing device, internal diameter have the gearing device outer shroud and the fastening screw trip bolt of tapering, external diameter has the pipe joint of chisel teeth and piping erection on same axis, two semicircle gearing devices cover outside the chisel teeth of pipe joint, the outside that is enclosed within two semicircle gearing devices that the gearing device outer shroud is level and smooth, with pin that the gearing device outer shroud is terminal fixing.
