Abstract
The utility model discloses a pressure test device for pipeline tightness, comprising a hydraulic press, an adjustment valve, a distributor, a pressure gauge and a plurality of cut-off valves, wherein the hydraulic press is connected with the distributor via a pipeline, one end of the adjustment valve is connected with the hydraulic press, and the other end of the adjustment valve is connected with a pipeline; and the plurality of cut-off valves are connected with the distributor respectively, and the pressure gauge is connected with the distributor as well. The pressure test device disclosed by the utility model is used for realizing a pressure test on a plurality of pipeline systems simultaneously and thus saving the test cost, and effectively protecting the hydraulic press and the pressure gauge simultaneously and thus prolonging the service lives thereof.
Description
Technical field
The utility model relates to a kind of line seal pressure testing device.
Background technology
In prior art, the signal piping sealing, generally that water pressure engine directly is connected on the pressure testing pipeline, and different pipe systems connect different water pressure engine, do not stop to suppress by water pressure engine, and observe the force value of water pressure gauge, make the pressure in pipe system reach test value, then whether the hand inspection pipe system is without leaking, and its defective is:
One, because the water pressure engine flow is limited, make the pressure in pipe system reach test value, its suppressed time needs longer;
Two, in test, to suppress by water pressure engine is single, its vibrations are larger, easily damage water pressure engine and tensimeter;
Three, when a plurality of pipe systems are tested, need a plurality of systems to suppress, therefore need nurse water pressure engine personnel more, cause the manpower waste;
Four, a plurality of systems suppress simultaneously needs the equipment of suppressing that increase more, increases testing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of and realizes that a plurality of pipe systems suppress simultaneously test and save the close property of the pipeline pressure testing device of testing cost.
For reaching above-mentioned purpose, solution of the present utility model is:
The close property of a kind of pipeline pressure testing device comprises water pressure engine, variable valve, divider, tensimeter and some stop valves; Water pressure engine is connected with divider by pipeline, and variable valve one end is connected with water pressure engine, and the other end is connected with pipeline; Some stop valves are connected with divider respectively, and tensimeter also is connected with divider.
Further, divider also is connected with the screw down nonreturn valve that is connected with the fire water pipeline.
Further, pipeline is copper pipe.
After adopting such scheme, the utility model is installed variable valve on water pressure engine, when the pressure that water pressure engine produces arrives test value, variable valve is opened automatically, guarantee the constant of test pressure, the personnel of need not nurse, and save human cost, and realize constant pressure and overload protection by variable valve, protect better water pressure engine and tensimeter; Divider realizes that a plurality of systems suppress simultaneously, tests simultaneously a plurality of pipe systems, saves testing cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Label declaration
Screw down nonreturn valve 6
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is elaborated.
Consult shown in Figure 1ly, the close property of a kind of pipeline pressure testing device that the utility model discloses comprises water pressure engine 1, variable valve 2, divider 3, tensimeter 4 and some stop valves 5.
Some stop valves 5 are connected with divider 3 respectively, and namely some stop valves 5 are relation in parallel, and tensimeter 4 also is connected with divider 3.
Divider 3 also is connected with the screw down nonreturn valve 6 that is connected with fire water pipeline (not shown).
When the utility model uses in test, some stop valves 5 are connected respectively to different pipe systems to be tested, and stop valve 5 Close Alls, the press 1 of fetching boiling water is suppressed; Adjust the pressure of variable valve 2, pressure reaches the test pressure value, and variable valve is opened automatically, has guaranteed that system pressure is constant, and water pressure engine has been carried out pressure protect, has strengthened the serviceable life of water pressure engine; , open stop valve 5 and the screw down nonreturn valve 6 that with fire water pipeline be connected, system is poured water and ftercompction thereafter, because fire water itself has the pressure of 0.3-0.4MPa, shortened the time that pipe system is suppressed, this moment, water pressure engine was only the ftercompction effect, can extend the serviceable life of water pressure engine; Again, establishment officer carries out pipe system integrality and leak check, confirms system integrity and sealing; At last, after system complete to be confirmed and sealing are intact, close water pressure engine 1 and fire water, complete test process.
The above is only preferred embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
