Description

Pipeline pressure testing device

Technical Field

The utility model belongs to the technical field of the pressure pipeline test technique and specifically relates to a pipeline pressure testing device.

Background

Pressure pipelines, and corresponding desuperheaters and desuperheaters are widely used in industry, and manufacturing units must perform strength water pressure tests after equipment processing is finished. Because the pressure of medium, the difference of temperature, flow and device length requirement for carry out intensity hydrostatic test's device has very big difference in the aspect of pipe diameter, nominal pressure and length, the intensity hydrostatic test device of a specification can't satisfy various different requirements, the manufacturing organization often adopts the welding pressure testing shrouding to solve intensity hydrostatic test, still need cut off the pressure testing shrouding after experimental completion, the pipeline needs secondary processing welding groove, complex operation, test cycle is long, high in manufacturing cost, and the device removes the difficulty in the testing process.

Disclosure of Invention

To exist not enough among the prior art, the utility model provides a pipeline pressure testing device solves above-mentioned complex operation, and test cycle is long, and manufacturing cost is high, and the device removes the problem of difficulty, through adjustment fastener, makes movable support tightly clip the offset plate and treats pressure testing pipeline both ends face, makes and treats that the pressure testing pipeline is in encapsulated situation, then through the water injection device with water injection pipeline in order to carry out the pressure testing. The utility model adopts the technical proposal that:

a pipeline pressure testing apparatus comprising: the adjustable water injection device comprises an adjusting support, a moving support, rubber plates, an upright post, a fastening device and a water injection device, wherein the upright post vertically penetrates through the rubber plates, and the distance between the two rubber plates can be adjusted according to the fastening device.

The adjusting support is trapezoidal, and 2-6 pairs are symmetrically arranged. The adjusting bracket is arranged on the movable bracket. The movable support is formed by welding a wallboard and a bottom plate. The bottom of the movable bracket is provided with a roller.

The rubber plate is arranged between the wallboard and two end faces of the pipeline to be tested. The upright posts are vertically sleeved in the wall board. The quantity of the stand columns is an even number which is more than or equal to 4, and the stand columns are uniformly arranged on the periphery of the circumference of the pipeline to be tested. The fastening device is a fastening nut. The water injection device comprises a water injection port and a sealing cover plate.

The utility model has the advantages that: as long as through fastener, impel the movable support tightly to clip the offset plate and treat pressure testing pipeline both ends face, make and treat that the pressure testing pipeline is in highly sealed state, a set of pipeline pressure testing device just can be used to the pipeline pressure testing of different pipe diameters, different nominal pressure, different length to give up and carried out the pressure testing with the welding pressure testing shrouding of different specifications. The step of welding and cutting is removed from, the operation is simple and convenient, the test period is shortened, and in addition, the roller arranged at the bottom of the movable support can facilitate the movement of the device. The utility model discloses but wide application in pipeline under pressure, desuperheater and temperature and pressure reducer's pressure test.

Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a pipeline pressure testing device, including: adjust support 8, removal support 11, offset plate 2, stand 3, fastener 6 and water injection device 4, the cover is worn perpendicularly in offset plate 2 to stand 3, and the interval of two offset plates 2 can be adjusted according to fastener 6. And adjusting the fastening device 6 to enable the movable support 11 to tightly clamp the two end faces of the pipeline 5 to be tested with the rubber plates 2, so that the pipeline 5 to be tested is in a highly sealed state. Wherein offset plate 2 can be directed against the pipeline pressure testing reuse of different specifications, be convenient for installation and dismantlement.

The adjusting support 8 is installed on the movable support 11 and is trapezoidal, the main used is to firmly support the pipeline 5 to be tested, 2-6 pairs of adjusting supports can be symmetrically arranged, and the problem of pressure test height difference caused by the pipe diameter can be adjusted. When the pipeline 5 to be tested is short, the adjusting supports 8 only need to be arranged at the head and the tail of the pipeline 5 to be tested respectively; if the pipeline 5 to be tested is long, a plurality of pairs of adjusting brackets 8 are required to be arranged in the middle to enhance the lifting force.

The movable support 11 is formed by welding a wall plate 1 and a bottom plate 7, the upright post 3 is vertically sleeved in the wall plate 1 in a penetrating way, the rubber plate 2 is arranged between the wall plate 1 and two end faces of the pipeline 5 to be tested, and when the fastening device 6 is adjusted, the wall plate 1 is folded to enable the rubber plate 2 to tightly clamp the two end faces of the pipeline 5 to be tested.

Enough margin is left in the tensile strength of the stand columns 3 to meet the requirements of different nominal pressures in the test, the number of the stand columns 3 is an even number which is more than or equal to 4, and the stand columns are uniformly arranged on the periphery of the circumference of the pipeline 5 to be tested. The quantity of stand 3 depends on the pipe diameter size of taking the pressure testing pipeline, and if the pipe diameter is great, then need more stands 3 for fix offset plate 2, the mode that evenly sets up guarantees that offset plate 2 all places atress is even.

Preferably, the fastening device 6 is a fastening nut, and a larger extrusion force can be generated along with the tightening of the fastening nut, so that the two end faces of the pipeline 5 to be tested are embedded into the rubber plates by 21-2 mm, and a better sealing effect is achieved.

The water injection device 4 includes a water injection port and a sealing cover plate for sealing the water injection port.

Preferably, the bottom of the movable bracket 11 is provided with a roller 9, so that the pipeline pressure testing device can be moved to any position.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
