Description
Technical field
The utility model relates to pipe fitting and hydraulic test of pipeline field, relates in particular to a kind of Portable water compression testing device.
Background technology
The pressure pipeline industry often needs product is carried out the hydraulic testing, guarantees that product can normally be on active service safely under service condition, avoids occuring security incident.The maximum difficult point of pressure pipeline (pipe fitting) the industry hydraulic testing is that the end part seal of pipeline (pipe fitting) is very difficult, and tradition is carried out the hydraulic testing to pressure pipeline (pipe fitting), need to leave certain surplus tubing at pipe end and weld end socket.After the hydraulic testing is finished, will weld end socket and unnecessary tubing and remove, its use is subjected to the restriction in place, is Bullet structure simultaneously, can not repeatedly use, and the pressure testing cost is high.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of Portable water compression testing device is provided, its design is ingenious, realized not at pipe end welding end socket, can reach again simultaneously the effect of end sealing, this sealing device for water pressure test performance is good, compact conformation, lightweight, good looking appearance, not limited by the place, installation test is convenient, and this Portable water compression testing device can repeatedly reuse safely, has greatly improved the efficient of the hydraulic testing, decrease the pressure testing cost, have a extensive future.
The utility model is achieved through the following technical solutions:
A kind of Portable water compression testing device, include the two card arc plates that cooperate with the testing pressure pipeline, plug, pressing plate, the web joint that distributes on sealing shroud and the card arc plate, it is characterized in that: described two card arc integrated circuit boards are contained on the testing pressure pipeline, the testing pressure pipeline oral area of described card arc front edge of board is provided with the plug that is mated is installed, described plug rear end is combined with sealing shroud, the described sealing shroud outside is equipped with pressing plate, the described pressing plate outside is provided with fixedly ear, be fixedly connected with locking, described pressing plate by strengthening screw rod between the web joint on described fixedly ear and the card arc plate, the middle part of plug is provided with the inlet hole water that is interconnected.
By the web joint fixing and locking at its two ends, be respectively equipped with mounting hole on the described web joint behind the described two card arc integrated circuit board dresses, have bolt to pass between the described mounting hole, and fix by nut lock.
The lateral wall of described plug is taper, and described sealing shroud is provided with the cone-shaped inner hole that cooperates with the plug tapered sidewalls.
The middle part of described pressing plate has the fit sealing screw rod to pass, and the middle part of the fit sealing screw rod water that is with hole, and the front end face of described plug and fit sealing screw rod correspondence position are provided with counterbore.
Being provided with into cylinder socket joint hole of the leading section of described fit sealing screw rod describedly entered cylinder socket joint hole and is communicated with the inlet opening.
Be fixed and clamped by hexagonal stiffening plate and nut between described fit sealing screw rod external part and the pressing plate.
Its principle is: by the fit sealing screw rod, make the taper plug outwards mobile, and the compression seal cover, sealing shroud outwards expands, and tube wall expands to sealing shroud can produce effect of contraction, makes between sealing shroud and the tube wall and produces normal pressure.In the hydraulic testing process, the hydraulic pressure pressure-acting makes plug, sealing shroud and tube wall that relative motion trend be arranged on plug, and then produces stiction.Hydraulic test pressure is larger, and it is also larger that plug bears pressure, and sealing shroud expands more obvious, and normal pressure is also larger between sealing shroud and the tube wall, and the stiction that produces also can be larger.When hydraulic testing pressure is higher, tube wall sealing position can produce mechanical relaxation, utilize card arc plate and web joint that hydraulic devices is strengthened, make this water test unit can bear pressure from pipe interior test(ing) liquid medium, guaranteed the safety and reliability of the hydraulic testing.
The utility model has the advantages that:
The utility model reasonable in design has realized can reaching again the effect of end sealing not at pipe end welding end socket, its good seal performance, compact conformation, lightweight, good looking appearance, not limited by the place, installation test is convenient, and this Portable water compression testing device can repeatedly reuse safely, has greatly improved the efficient of the hydraulic testing, decrease the pressure testing cost, have a extensive future.
Description of drawings
