Description
Technical field
The utility model is related to pipeline manufacture field, the hydrostatic pressing test dress of more particularly to a kind of pipeline with joint
Put.
Background technology
Pipeline be with pipe, pipe connector and valve etc. be connected into be used for convey gas, liquid or with solid particle
Fluid device.Generally, after fluid is pressurized through air blower, compressor, pump and boiler etc., low pressure is flowed at the high pressure of pipeline
Place, can also be used pressure or the gravity conveying of fluid itself.Having many uses for pipeline is general, be used primarily in feedwater, draining, heat supply,
Give gas, long distance delivery oil and natural gas, agricultural irrigation, in hydraulic engineering and various commercial plants.
Expansion joint, is also compensation of pipeline joint, is the new product that the equipment such as pump, valve, pipeline are connected with pipeline, passes through
Bolt connects equipment with pipeline and expansion joint, becomes entirety, and expansion joint has certain displacement, so
It can be just adjusted in installation and maintenance according to in-site installation size, operationally, axial thrust can be reached whole pipe
Road system.Operating efficiency is so not only improved, and certain protective role is played to equipment such as pump, valves.
Additionally due to pipeline extension swell increment is big, bearing temperature is high, compression area is larger, it is basic in water ＆ wastewater engineering for building
Concrete pour into a mould or pre-buried pipeline, in these engineerings, pipeline by building foundation settlement, equipment resonance, geology change with
And during pipeline medium change, the position of pipeline distribution starts stress, deformation, distortion so as to destroy pipeline.Therefore when long
Between great inconvenience to unit in charge of construction is brought by the rupture of pre-buried pipeline, in order to overcome these difficult, it is ensured that the safety of pipeline
Operation, using expansion bend or expansion joint, it can in certain scope axial stretching, overcome the various angular shifts of pipeline,
Decentraction, flexible, expansion.Pipeline can freely stretch in expansion bend or expansion joint, once more than maximum stroke,
Expansion joint itself plays position-limiting action, so as to ensure that pipe safety is run.
The manufacture of expansion joint needs to use mould molding and welding fabrication, after fabrication is complete, stretched to examine
The quality that the quality of reducer coupling head and pipeline, especially welding fabrication are completed, often to injecting liquid in the pipeline, utilizes liquid
The pressure impact weld of generation, as hydrostatic pressing is tested.

Steam vent 07 is located between ullage, the flange 03 of two pipelines to be connected using some connecting screw rods 02, prevents method
Orchid 03 is moved.From water injection hole 06 to the device internal water flooding, the air being expelled from inside device by water flows out from steam vent 07, directly
After being filled to water, steam vent 07 is closed, hydrostatic pressing test instrumentation is connected from water injection hole 06.Between two expansion joints 04
One end adjustment gap 09 is left, nylon rod 05 and rubber are all provided between the side wall of steel sleeve 01 and two expansion joints 04
Circle 08, nylon rod 05 be used for make closely to connect between the side wall of expansion joint 04 and the side wall of steel sleeve 01, and rubber ring 08 be for
Prevent the water in pipeline from being discharged from adjustment gap 09.But the hydrostatic pressing detecting device of the expansion joint 04 has following lack
Point：
1. usually, connecting screw rod 02 is not settable long, otherwise too small for the fixed force of two end flanges 03, then surveying
During examination, flange 03 can be moved due to the pressure of water, cause water to flow out, and connecting screw rod 02 can be set it is long mean test
Duct length be restricted；
2. the type of test is restricted, if a pipe ends all connect expansion joint 04, it is not suitable for above-mentioned
Test equipment.
