Description
Technical field
This utility model relates to a kind of pressure tester for tubes.
Background technology
Ship pipe occupies very important effect and share during being produced on shipbuilding at present.According to statistics, the making of pipe and the workload of installation account for about the 20% of whole shipbuilding quantities, and almost each shipyard has the professional pipe atelier of oneself.Pipe is after workshop makes, whether pipe reaches requirement with the weld of flange, if there is leakage scenarios, this is accomplished by being verified by pipe hydraulic pressure strength, and the hydraulic pressure strength test of pipe to be also shipowner and ship examine the project extremely paid close attention to, be shipowner and ship inspection must look into project.Tested by pipe hydraulic pressure strength, can determine whether the fine or not situation of tube welding quality.
In this context, shipyard is badly in need of a kind of tooling device to meet the demand of pepe shop pressure testing, and it is simple, practical, flexible to operation and use the features such as safety that it has making, and can reach disposably to put into, the permanent purpose used.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of pressure tester for tubes, can meet the requirement of shipyard workshop pipe pressure test, have one and fill multiplex function.
This utility model the technical scheme is that for solving its technical problem
A kind of pressure tester for tubes, including main pipeline, a plurality of lateral, two flanges, blank flanges, two flanges are separately mounted to the initial and end end of main pipeline, blank flange is arranged on the flange of main pipeline tail end, described a plurality of lateral is distributed in main pipeline both sides along main pipeline length direction, every lateral one end connects with main pipeline, the other end is for connecting with pressure testing pipe, being provided with stop valve, pressure gauge valve, Pressure gauge on every lateral, described Pressure gauge is arranged on pressure gauge valve.
Further, described main pipeline and lateral are respectively adopted seamless steel pipe making.
Further, described seamless steel pipe plating zinc on surface processes.
Further, described lateral is provided with for installing the nipple one being connected with pressure testing pipe, and for installing, with pressure gauge valve, the nipple two being connected.
Further, described nipple one, nipple two are respectively welded on lateral.
Further, described stop valve uses bronze stop valve, and described pressure gauge valve uses bronze pressure gauge valve.
Further, the head end of described main pipeline passes through Flange joint feed pipe or water pump.
The beneficial effects of the utility model are: this utility model is applicable to the pipe hydraulic pressure strength test of shipyard workshop, workshop hydraulic pressure strength pressure testing such as pipes such as ballast tube, extinguishing pipe, bilge pipe, fuel feed pipes, the pipe hydraulic pressure strength test of the various pressure requirements in shipyard workshop can be met, have one and fill multiplex function.It is simple, practical, flexible to operation and use the features such as safety that this device has making, and belongs to disposable input, the permanent tooling device used, and has investment little, the advantage having high repayment.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 be in Fig. 2 A-A to structural representation.
In figure, label represents: 1. stop valve, 2. pressure gauge valve, 3. Pressure gauge, 4. flange, 5. blank flange, 6. nipple one, 7. nipple two, 8. lateral, 9. main pipeline.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Referring to figs. 1 through Fig. 3, a kind of pressure tester for tubes of the present utility model, including main pipeline 9, a plurality of lateral 4, blank flange 5 of 8, two flanges.Two flanges 4 are separately mounted to the initial and end end of main pipeline 9, and blank flange 5 is arranged on the flange 4 of main pipeline 9 tail end, for being blocked by the tail end of main pipeline 9;The head end of main pipeline 9 is connected to feed pipe or water pump by flange 4.
Described a plurality of lateral 8 is distributed in main pipeline 9 both sides along main pipeline 9 length direction, every lateral 8 one end connects with main pipeline 9, the other end is for connecting with pressure testing pipe, being provided with stop valve 1, pressure gauge valve 2, Pressure gauge 3 on every lateral 8, described Pressure gauge 3 is arranged on pressure gauge valve 2.
Described main pipeline 9 and lateral 8 are respectively adopted seamless steel pipe and make, and the zinc-plated process of steel tube surface, described stop valve 1 uses bronze stop valve, and described pressure gauge valve 2 uses bronze pressure gauge valve, improve the anti-corrosion capability of parts, with the service life of extension fixture.
Described lateral 8 is welded with for installing the nipple 1 being connected with pressure testing pipe, and for installing, with pressure gauge valve 2, the nipple 27 being connected, makes device install more efficient and convenient.
The above, preferred embodiment the most of the present utility model, this utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
