Abstract
The utility model relates to a metal-plastic composite tube inner expansion device. The utility model is composed of a valve body, a pin shaft seat, a piston rod, a lever, an oil filling opening, an air bleed screw, an oil tank, an oil pipe and an oil cylinder body, wherein a fixed disk seat is fixed on a delivery outlet of the oil cylinder body; the outside of the disk seat is connected with the pull rod. The utility model is characterized in that an expansion ring composed of plastic polyurethane rings is also fixed between the disk seat and the pull rod. The utility model has the advantages of simple and reasonable structure and labor saving operation, avoids the defect that pipes are unevenly stressed to generate edge angles, displacement, gaps, etc. and is also suitable for any metal pipe with a thin wall; the utility model is especially suitable to be used on construction sites, and the sealing effect is good; the utility model also has the function of automatic compensation, and the utility model can automatically correct in a small range and automatically fill gaps of pipe grooves; the purposes of convenient construction, quickness, high safety, reliability and labor saving are achieved.
Description
Technical field
The utility model belongs to the device that multiple composite metal-plastic pipes is installed, and especially is fit to the composite metal-plastic pipe internal-expansion type device of connection, installation and the site operation of steel-plastic composite pipe.
Background technology
Traditional composite metal-plastic pipe mainly adopts mechanical systems such as clamp-press type or differential formula to connect: this connecting tube manufacturing cost height, required accessory is many, bonding strength and poor reliability, sealing is easily worn out behind intermediate link multioperation complexity, the use certain hour, causes seepage.
Summary of the invention
The purpose of this utility model provides a kind of bonding strength and reliability height, and easy-operating composite metal-plastic pipe internal-expansion type device is to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of valve body, axis pin base, piston rod, lever, pouring orifice, bleed screw, fuel tank, oil pipe, cylinder body, wherein on the delivery outlet of cylinder body, be fixed with a fixed disk seat, the dish seat is externally connected with a pull bar, is characterized in: also be fixed with an expansion loop between dish seat and pull bar;
Above-mentioned expansion loop is made by plasticity polyamine alicyclic ring.
Major advantage of the present utility model is simple and reasonable, rapid operation, avoided making the tubing unbalance stress and drawbacks such as corner angle, displacement, space occur, also is fit to use any thin-wall metal tube.Be particularly suitable for the job site and use good sealing effect.The utility model also possesses automatic compensation function, can calibrate, fill up automatically the space of pipe fitting groove among a small circle automatically.Easy construction, quick, safe, reliable, labour-saving purpose have been realized.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the utility model working state schematic representation.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model constitutes (see figure 1) by valve body 1, axis pin base 2, piston rod 3, lever 4, pouring orifice 5, bleed screw 6, fuel tank 7, oil pipe 8, cylinder body 9, dish seat 10, expansion loop 11, pull bar 12.Expansion loop 11 is to be made by plasticity polyamine alicyclic ring, carry out the transmission (see figure 2) of power by the distortion of expansion loop 11, because expansion loop 11 can be exerted oneself in 360 ° of circumference range simultaneously, avoided making the tubing unbalance stress and drawbacks such as corner angle, displacement, space occurred.
The utility model before use, steel-plastics composite pipe 15 is at first with the dedicated pipe cutter steel to be moulded pipe to cut (see figure 3) by Len req with the connected mode of its pipe fitting 14, with special-purpose full circle instrument steel is moulded pipe 15 port inner walls then and carry out full circle, again steel moulded pipe port and seal processing, can carry out interior expanded joint to the steel-plastics composite pipe pipe fitting 14 supporting and connect work with it.
The utility model at first injects an amount of hydraulic oil by pouring orifice 5 in use in fuel tank 7, screw bleed screw 6; Load onto supporting pull bar 12, position-arresting disk 13, expander 11 by the specification of tubing, pipe fitting; Then ready steel-plastics composite pipe 15 is inserted in the corresponding pipe fitting 14, again steel-plastics composite pipe 15 and corresponding pipe fitting 14 is inserted in the internal-expansion type pipeline fastening means simultaneously, be as the criterion to position-arresting disk 13 positions.Shake lever 4 up and down continuously, the hydraulic cylinder piston action drives pull bar 12 and does axial displacement, makes expansion loop 11 compression-expansion, power is passed to steel-plastics composite pipe 15 inwalls, thereby steel-plastics composite pipe 15 is closely fit together with corresponding pipe fitting 14 annular grooves.12 mobile distances of pull bar should be made suitable adjustment according to the size that steel is moulded tubing, pipe fitting.After interior expansion rule cun puts in place, unscrew bleed screw 6, treat that can extract steel out behind expansion loop 11 and pull bar 12 returns moulds pipe 15 and pipe fitting 14.Steel should guarantee that tubing is identical with the specification of pipe fitting before moulding and expanding in the pipe, and the device size that expands in inserting puts in place, and in the process that expands mouthful, can't be crooked, the axiality of assurance tubing, pipe fitting and inner bulging gate device.
Drive unit of the present utility model can adopt the driving of hand-hydraulic, electric hydaulic and any mechanical energy.
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
