Description
Technical field
The utility model is related to pipeline pressure test equipment technical field, especially a kind of pipeline pressure testing device.
Background technology
When carrying out an acceptance inspection to pipeline, need to carry out pressure testing to pipeline.Existing pipeline pressure test method is different pressures
The independent pressure testing of pipeline of power grade, pressure testing process is comparatively laborious, expends a large amount of manpower and time.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of pipeline pressure testing device, it is reasonable for structure, it is simple and convenient,
Can pressure testing be carried out to pipeline well.
The technical solution of the utility model is：A kind of pipeline pressure testing device, including plugging plate, automatic exhaust steam valve, communicating pipe,
Equipment, tap, high-pressure hose, hydraulic test pump, first pressure gauge, second pressure gauge, control valve and pipe network, the plugging plate connection
Pipe network is sequentially connected automatic exhaust steam valve, communicating pipe and first pressure gauge on the pipe network, connects equipment the communicating pipe, described
The another way of the connection tap all the way of pipe network, the pipe network connects hydraulic test pump by high-pressure hose, and the hydraulic test pump is equipped with
Second pressure gauge, the hydraulic test pump are connected to also by pipeline all the way with the pipeline all the way where tap, the pipe network and Ge Lu
Control valve is equipped on pipeline.
Preferably, the plugging plate is steel plate or flange closure plate.
Compared with prior art, the utility model has the advantages that：A kind of pipeline examination provided by the utility model
Pressure device, can be to the independent pressure testing of pipeline that pipeline pressure test method is different pressures grade, and loading test effect is fine, reasonable for structure, letter
Just, pressure testing process is not cumbersome for folk prescription, without expending a large amount of manpower and time.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode, the utility model is described further.
As shown in Figure 1, a kind of pipeline pressure testing device, including plugging plate 1, automatic exhaust steam valve 2, communicating pipe 3, equipment 4, the fire hose
First 5, high-pressure hose 6, hydraulic test pump 7, first pressure gauge 8, second pressure gauge 9, control valve 10 and pipe network 11.
Plugging plate 1 is steel plate or flange closure plate.
Plugging plate 1 connects pipe network 11, and automatic exhaust steam valve 2, communicating pipe 3 and first pressure gauge 8 are sequentially connected on this pipe network 11,
Connect equipment 4, the tap of connection all the way 5 of this pipe network 11 communicating pipe 3, the another way of this pipe network 11 is connected by high-pressure hose 6
Hydraulic test pump 7, hydraulic test pump 7 are equipped with second pressure gauge 9, and hydraulic test pump 7 is also by the pipeline all the way where pipeline all the way and tap 5
On connection, the pipe network and Ge Lu pipelines (including pipeline between the two-way pipeline of pipe network connection, hydraulic test pump and tap)
Equipped with control valve 10.
The operation principle of the utility model is：
(1) chilled water pipe test pressure is 1.2Mpa；
(2) equipment in the pipeline for needing to carry out pressure testing is bypassed with tap, by pipe network end steel plate or method
Blue closure plate is blocked, and upper all blowdown valves of blinding off a line are (if setting can be set according to actual needs at the bottom of whole device
Portion), start to system water filling, while in open system each eminence air bleeding valve.After filling water, air bleeding valve and intake gate are closed
Valve stops to system water filling；
(3) valve for opening connection electric pressure test pump pressurizes to system, while unscrewing the plug valve on pressure gauge, observation pressure
Pressure value on power table rises situation, generally divides 2~3 times and rises to test pressure.In the process, when certain numerical value of often pressurizeing,
It should stop and pipeline is comprehensively checked, can be further continued for pressurizeing after phenomenon without exception；
(4) pressure testing rises to voltage stabilizing 10min pressure drops after test pressure and is not greater than 0.02Mpa, then by system pressure
It is reduced to operating pressure, voltage stabilizing 60min, visual examination ne-leakage is qualification；
(5) after pressure testing qualification, whole waters in pipeline is bled off, test data sheet is filled in.
The above embodiments are only the preferred embodiment of the utility model, and the right of the utility model cannot be limited with this
Range, therefore, modification made according to the patent scope of the utility model, equivalent variations, improvement etc. still belong to the utility model institute
The range covered.
