Whether common pressure pipeline pick-up unit only can leak by detected pressures pipeline, but the leakage position concrete for pressure pipeline cannot judge accurately, and when pressure pipeline being revealed gap and being less, operating personnel cannot judge even cannot judge whether it reveals in its concrete leakage position; And then cause pressure pipeline cannot repair in time when meeting with minor issue and revealing, when the expansion of leakage problem, then can affect the normal production of enterprise.
Summary of the invention
For above-mentioned Problems existing, the utility model object is to provide a kind of simple to operate, controls precisely, to facilitate the pick-up unit of accurate positioning pressure pipeline leakage position.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of pick-up unit of pressure pipeline, described pick-up unit comprises vacuum pressure pump, control center, sealing termination and pressure detection annulus, described sealing termination is sealedly connected on the two ends of pressure pipeline, described sealing termination is provided with pressure pipeline and is connected on vacuum pump, the both sides of described pressure detection annulus are provided with setscrew nut and are fixedly connected on pressure pipeline, the inner side of pressure detection annulus is provided with the pressure measurement groove of annular, pressure measurement groove is provided with the elastic seal ring of twice annular, the inner side of described pressure measurement groove is provided with pressure transducer, described pressure transducer through connection in the controlling in the heart.
Improve as one of the present utility model, described pressure detection annulus is made up of the semicircular seal casinghousing of twice, and the link position of two seals housing is provided with set nut and seal; The pressure detection annulus formed by semicircular seal casinghousing, dismounting and easy for installation, be convenient for changing the detection position of pressure pipeline, operate time saving and energy saving.
Improve as one of the present utility model, the width of described pressure measurement groove is greater than the width 1 ~ 2cm of weld seam on pressure pipeline; When pressure measurement slot is when the leakage position of pressure pipeline, the gas revealed enters pressure measurement groove, and pressure measurement groove itself is sealing, pressure in pressure measurement groove raises, by pressure transducer with directly find out that pressure changes, it is convenient to facilitate, and on pressure pipeline, position while welding is the easy leak point of pipeline, the conveniently Measurement accuracy of device, the width of pressure measurement groove must be greater than its width.
Improve as one of the present utility model, described sealing termination comprises pressure measurement termination and ventilation termination, described ventilation termination is connected on vacuum pump by pressure pipeline, and described pressure measurement termination is provided with pressure detection head, and described pressure detection head via line is connected in control center; By the overall co-ordination of pressure measurement termination with ventilation termination, precisely can detect a certain section of pressure pipeline and whether reveal, when determining that this section of pressure pipeline is revealed, accurately measure it by pressure detection annulus and revealing position.
Improve as one of the present utility model, the internal diameter size of described pressure detection annulus and the external diameter size of pressure pipeline match; Caliber due to pressure pipeline has a variety of, and therefore in order to ensure the sealing effectiveness of this device, the size of both contact positions must match.
The utility model has the advantage of: the pressure detection circular ring structure of the utility model by matching with pressure pipeline, the convenient welding position to pressure pipeline and tube wall carry out testing, leakage position on precise positioning pressure pipeline, detected by instrument and act on behalf of manual observation, the precision of device is higher; When doubtful leakage occurs pressure pipeline, this device can be adopted to carry out detection and positioning, simple to operate, time saving and energy saving; Can handled easily personnel on-call maintenance after having operated, avoid the enlarged areas of pressure pipeline leak point.
