Description
Technical field
The utility model relates to gas pipeline joint weld intensity detection field, is specifically related to a kind of checkout gear of polyvinyl fuel gas pipeline butt fusion welding joint weld intensity.
Background technology
Polyethylene pipe owing to having the feature such as excellent chemical resistance, good flexibility and impact resistance, cheap and easy construction, in the development of fuel gas transmission field rapidly.But the length that polyethylene pipe has when dispatching from the factory obviously can not meet the requirement of pipe laying.Meanwhile, often need between pipeline to carry out reducing, increase branch road or carry out pipeline maintenance etc., these work all relate to the welding of pipeline.The welding of polyvinyl fuel gas pipeline is most important link in pipe-laying process, and the detection of docking port weld strength is the key ensureing that whole piece fuel gas transmission networking security is run.At present, the detection method adopted is destructive selective examination, after random selecting one section of weld bond both sides are sawed-off, be cut into sheet again (mainly because the intensity of pipe is large, manpower cannot be broken disconnected, and cannot detect), bandpass is 3-20mm, welding junction is broken with hand by testing staff, observe interface and whether occur brittle fracture, judge that whether welding junction intensity is qualified with this, the advantage of this method to carry out job site detection, save time, cost of labor is low, shortcoming is that inspecting force does not have standard, also cannot accurately perform, human factor (size of the individual strength) impact on testing result of testing staff is very large, the degree of accuracy of testing result is very low.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming existing polyvinyl fuel gas pipeline butt fusion welding joint weld intensity onthe technology of site test, there is provided that a kind of degree of accuracy is high, structure is simple, easy to use, can be used in the on-site detecting device of polyethylene pipe hot melt butt welding joint weld intensity.
The technical solution adopted in the utility model is: a kind of checkout gear of polyethylene pipe hot melt butt welding joint weld intensity, its main points are, it comprises screw rod, fixed support, connecting rod, pressure head, sample holder, limiting plate, fixed support comprises base, two heel posts, crossbeam, the parallel both sides being fixed on base of two columns, beam vertical is fixed on two heel posts, the screwed hole matched with screw rod is processed with in the middle part of crossbeam, screw rod is fixed on crossbeam, the below of screw rod is fixed wtih connecting rod, pressure head is fixed with below connecting rod, sample holder is fixed on base, limiting plate is fixed on base center, height is lower than sample holder, be positioned at the below of pressure head.
When using the utility model, same as the prior art, adopt destructive selective examination, after random selecting one section of weld bond both sides are sawed-off, be cut into sheet again, section of jurisdiction is placed on sample holder, the inner surface soldering opening of section of jurisdiction is facing to pressure head, moved down by screw rod, screw rod is moved down by connecting rod band dynamic head, and pressure head is pushed down welding junction and moved down, move to till contacting with limiting plate, when pressure head is depressed into limiting plate welding junction, if brittle fracture phenomenon does not appear in interface, then illustrate that welding junction intensity is qualified.The power resources of this device are in the downward active force of screw rod, and do not need applying power equipment, structure is simple, easy to operate.Because the distance between limiting plate and sample soldering opening is unified, so inspecting force is unified, identical to the soldering opening inspecting force of all identical calibers like this, the impact of not examined personnel's individual factor, the degree of accuracy of testing result is high.
Screw rod upper end is fixed with rocking bar.Easy to operate like this.
Be fixed with the connecting rod fixed support parallel with crossbeam at the middle part of two heel posts, the support bracket fastened middle part of connecting rod is processed with can through the through hole of connecting rod.
Connecting rod fixed support is not only fixed connecting rod, strengthens the intensity of connecting rod, prevents connecting rod swing, the intensity of two heel posts is also had to the effect of enhancing simultaneously.
Pressure head is up big and down small cone.The top of pressure head is spherical.When operating, detected sample is placed on sample holder, and the least significant end of pressure head contacts with the welding junction of detected sample, maximum to ensure the pressure that welding junction bears.
Be fixed with the limiting plate that can move up and down in the below of limiting plate and regulate support.The height of limiting plate can regulate support to adjust by limiting plate, during detection, according to the parameter such as material, hardness, external diameter, wall thickness of detected sample pipeline, selects suitable limiting plate height.Such the utility model can detect the polyethylene gas pipe of all specifications.
The utility model has the advantage of that the job site that can be used for polyvinyl fuel gas pipeline butt fusion welding welding junction intensity is detected, save time cost and cost of labor, detection efficiency is high.Compared with existing detection method, the degree of accuracy of the utility model device is high, structure is simple, overall specification is little, and cost is low, portable, easy to use, is convenient to application and promotes.
