Technical field
The utility model belongs to PE pipe fitting technical field, particularly relates to a kind of PE steel and moulds adapter pick-up unit.
Background technology
Pipe moulded by PE steel, is widely used in present production, life.It is various that pipe classification moulded by PE steel, and Various Functions, the purposes wherein comparing main flow uses as water delivery (oil) pipe, gas piping etc.Pipe moulded by PE steel as water-supply-pipe, gas piping; often needed length is longer; many pipes are needed to dock; so at present when producing; PE often can be adopted to take over the mode of docking with steel pipe main body (steel pipe or steel pipe outsourcing PE heat-shrink tube) dispatch from the factory; wherein steel moulds tube body for water delivery, gas transmission, and PE adapter is then one section of pipe fitting being connected on that tube end moulded by steel, and PE steel can be facilitated to mould docking (mode such as clamping, hot-melt adhesive paste) between pipe.And outside linkage section, generally also can overlap the preceding paragraph clip, for strengthening PE adapter and steel moulds connection between tube body and sealing.
In the PE steel plastic pipe of the above-mentioned type, linkage section is the position of the easiest seal failure, leakage, so need the detection it being carried out to sealing before dispatching from the factory.And when sealing propertytest being carried out to the linkage section of the above-mentioned type PE steel plastic pipe in prior art, (it is few that PE takes over the situation consistent with steel pipe inner major diameter by two of different bore block heads to need to utilize cylinder, usually dividing of size is had, can be that PE adapter internal diameter is larger, also can be that steel pipe inner major diameter is larger, specifically depending on demand) from two ends press-in pipe fitting, then the linkage section after shutoff is inflated, then carry out the observation of air pressure change, thus whether measure sealing up to standard.In the convenience, the stability of testing process, the accuracy of testing result etc. of detection operation, still there is shortcoming.
Utility model content
The utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, fast and effeciently can carry out the two ends shutoff of steel plastic pipe linkage section, plugging operations is coherent efficient, the sealing of shutoff end is good, and testing process is stablized, and can ensure the device that testing result accuracy is high.
To achieve these goals, the utility model is by the following technical solutions:
Adapter pick-up unit moulded by a kind of PE steel, comprise the base seat board for placing tested pipe fitting, for the top base plate of fixing master cylinder, the air pump of gas and the baroceptor for detecting air pressure is detected for providing, described base seat board, the equal level of top base plate, described base seat board, be connected and fixed by some columns between top base plate, described top base plate is provided with master cylinder, the piston rod of master cylinder passes top base plate and connects an adjusting bracket, described adjusting bracket is provided with adjusting cylinders, sealing, described sealing comprises two large rings, two positions are lower than the little ring of arbitrary large ring, all large rings, coaxial and the level of little ring, there is between two large rings large ring and regulate gap, there is between two little rings little ring and regulate gap, described large ring, little ring is equipped with oblique outer edge, oblique outer edge on two large rings is relative, large ring seal groove is formed between oblique outer edge on two large rings, oblique outer edge on two little rings is relative, little ring seal groove is formed between oblique outer edge on two little rings, large ring seal groove, large sealing packing ring is respectively equipped with in little ring seal groove, small sealing ring, the piston rod of adjusting cylinders connects an adjustable column, the adjustment barrel be slidably connected with adjustable column is arranged with outside adjustable column, the large ring that in two large rings, position is lower, the little ring that in two little rings, position is higher is all connected with adjustment barrel, the little ring that in two little rings, position is lower is connected with adjustable column lower end, the large ring that in two large rings, position is higher is connected with adjusting bracket, described adjustable column is provided with air flue, described adjustment barrel is provided with the pore be communicated with air flue, described air flue is communicated with air pump, described base seat board is provided with and is threaded and vertical adjusting screw(rod) with base seat board, adjusting screw(rod) upper end is above base seat board, adjusting screw(rod) lower end is provided with swing handle, swing handle is in below base seat board, base seat board is located on a underframe, adjusting screw(rod) is provided with some gag lever posts, gag lever post upper end and adjusting screw(rod) upper end thereof, end in contact bottom susceptor plate top surface under gag lever post.When the piston rod of master cylinder stretches out, can directly two large rings, two the related large sealing packing rings of little ring, small sealing rings all be stretched in tested pipe fitting, adjusting cylinders piston rod shrinks then can allow two large rings compress mutually, two little rings compress mutually, thus compressing O-ring seal makes its distortion that stretches out, be adjacent to tube wall, realize sealing.One end that tested pipe fitting internal diameter is less needs to place down.Tested pipe fitting can be enclosed within outside adjusting screw(rod), gag lever post, then turn swing handle makes adjusting screw(rod) move down, thus press down gag lever post, because under gag lever post, end in contact bottom susceptor plate top surface cannot move down, so gag lever post lower end can outer be moved, thus the inwall of tested pipe fitting lower end can be held out against, play the effect of auxiliary positioning.
