Abstract

The utility model provides a pipeline pressure testing buffer, including buffer tank and support, the buffering canning is on the support, install the pressure pipe on the buffer tank, the manometer is installed to the pressure pipe other end, the both ends of buffer tank are connected with first nozzle stub and second nozzle stub respectively, first nozzle stub and second nozzle stub all communicate with each other with the buffer tank inner chamber, install first ooff valve and second switch valve on first nozzle stub and the second nozzle stub respectively, the first nozzle stub other end is connected with and is used for and waits to detect the first hose that the pipeline is connected, the second nozzle stub other end is connected with and is used for the second hose be connected with the hydraulic test pump. The utility model discloses can cushioning the water under high pressure that the force (forcing) pump jetted out, preventing that it from directly leading to the fact the impact to the pipe wall, the pipeline is waited to detect in effective protection.

Description

A kind of pipeline pressure test buffer unit
Technical field
This utility model is related to pipeline leak detection field tests, is especially a kind of pipeline pressure test buffer unit.
Background technology
After the completion of new pipeline construction, generally can all leak detection test be carried out to it, way in the past is directly to use force (forcing) pump The water pressure test is carried out to pipeline, because pipeline is joined directly together with force (forcing) pump, after the power supply for connecting force (forcing) pump, water under high pressure can moment Into in pipeline, tube wall is impacted, cause tube wall to damage.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of pipeline pressure test buffer unit, and force (forcing) pump can be penetrated The water under high pressure for going out enters row buffering, prevents it from directly impacting to tube wall, effective protection pipeline.
Technical solution of the present utility model is to provide a kind of a kind of buffering of pipeline pressure test with following structure dress Put, including surge tank and support, buffering is potted on support, the two ends of surge tank are connected to the first short tube and second short Pipe, the first short tube and the second short tube are communicated with surge tank inner chamber, are separately installed with first on the first short tube and the second short tube and are opened Valve and second switch valve are closed, the first short tube other end is connected with the first flexible pipe for being connected with pipeline to be detected, the second short tube The other end is connected with the second flexible pipe for being connected with hydraulic test pump.
A kind of pipeline pressure test buffer unit described in the utility model, wherein, manometer tube, manometer tube are installed on surge tank The other end is provided with pressure gauge.
A kind of pipeline pressure test buffer unit described in the utility model, wherein, controlled valve is installed on manometer tube.
After using above structure, compared with prior art, a kind of pipeline pressure test buffer unit of this utility model has following Advantage:
1st, during pressurization pump priming is suppressed, surge tank can play cushioning effect, water under high pressure is steadily entered to be checked In test tube road;
2nd, due to the cushioning effect of surge tank, High-Pressure Water will not directly impact tube wall, and corresponding tube wall also would not be subject to Damage, and then play the protective effect to pipeline;
3rd, when some small-caliber pipelines are detected, the water yield in pipe with small pipe diameter is more plus the water yield inside surge tank, can be with Ignore the impact that the temperature difference is produced to pressure completely.
Manometric setting is available for people to grasp the concrete pressure value of water under high pressure in real time.
Description of the drawings
Fig. 1 is that structure when a kind of pipeline pressure test buffer unit of this utility model is mounted between force (forcing) pump and pipe under test is shown It is intended to.
Specific embodiment
A kind of pipeline pressure test buffer unit of this utility model is made further in detail with reference to the accompanying drawings and detailed description Describe in detail bright:
As shown in figure 1, in this embodiment, a kind of pipeline pressure test buffer unit of this utility model includes surge tank 9 and support 15, surge tank 9 is mounted on support 15, and the two ends of surge tank 9 are connected to the first short tube 16 and the second short tube 10, First short tube 16 and the second short tube 10 are communicated with the inner chamber of surge tank 9, are separately installed with the first short tube 16 and the second short tube 10 First switch valve 6 and second switch valve 14, it is first soft that the other end of the first short tube 16 is connected with for being connected with pipeline to be detected 3 Pipe 5, the other end of the second short tube 10 is connected with the second flexible pipe 11 for being connected with hydraulic test pump 13.
In order to grasp the concrete pressure value of water under high pressure in real time, manometer tube 17, the other end of manometer tube 17 are installed on surge tank 9 Pressure gauge 7 is installed, controlled valve 8 is installed on manometer tube 17.
When leak detection test is carried out to pipeline, an end of the second flexible pipe 11 is connected on the water inlet short tube 12 of hydraulic test pump 13, will One end of the first flexible pipe 5 is connected on the water outlet short tube 4 of pipeline to be detected 3, and the power supply for connecting hydraulic test pump 13 can be to be checked to carrying out Test tube road 3 is tested.
Embodiment described above is only that preferred implementation of the present utility model is described, not to this practicality New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall in protection domain of the present utility model.
