The purpose of this utility model is achieved through the following technical solutions:
A kind of pipeline pressure test head, the pressure testing pipe including one end with ellipse head, is set to spaced in pressure testing pipe
1# pipe cleaner and 2# pipe cleaner, and pressure testing pipe medium injection pipe disposed in parallel, be respectively arranged at pressure testing pipe tail portion seal head end, in
Between and front by pressure testing pipe and medium injection pipe 1# connecting tube interconnected, 2# connecting tube, 3# connecting tube, be respectively arranged at
1# connecting tube, 2# connecting tube, the 1# valve in 3# connecting tube, 2# valve, 3# valve, be set to 1# pipe cleaner rear end it is hollow every
Plate is set to the pressure sensor, temperature sensor and pressure gauge of pressure testing pipe front end, is provided in the arrival end of medium injection pipe
Flowmeter, the external high-pressure hydraulic pump of medium injection pipe or air compressor.
The utility model can push the water in 2# pipe cleaner and pressure testing pipe to move ahead towards to pressure testing water pipe direction by injection water,
It presses to pressure testing water pipe, and while water filling, not only rinsed pressure testing pipe but also excludes the air in pipeline section.In water filling pressure testing process
In, monitoring system can record time in pressure testing overall process, temperature, three parameter of pressure in real time, realize whole uninterrupted recording
And pressure volume curve figure is formed, record data are comprehensive, and record result is accurate, obtain accurate believable pressure testing result.
The utility model structure is simple, easy to use, and reusable, is tested respectively each pipeline section of water pipe.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the schematic diagram that the utility model connect pressure testing with pressure testing pipeline section.
Specific embodiment
Pipeline pressure test head as shown in Figure 1, the pressure testing pipe 1 including one end with ellipse head 2, between being set in pressure testing pipe
Pressure testing pipe is respectively arranged at pressure testing pipe medium injection pipe 4 disposed in parallel every 1# pipe cleaner 3a and 2# the pipe cleaner 3b of setting
Tail portion seal head end, centre and front by pressure testing pipe and medium injection pipe 1# connecting tube 5a, 2# connecting tube 5b, 3# interconnected
Connecting tube 5c is respectively arranged at 1# connecting tube, 2# connecting tube, 1# valve 6a, 2# valve 6b, 3# valve 6c in 3# connecting tube,
It is set to the hollow clapboard 7 of the rear end 1# pipe cleaner 3a, the pressure sensor 8 for being set to pressure testing pipe front end, temperature sensor 9 and pressure
Power table 10 is provided with flowmeter 11, the external high-pressure hydraulic pump of medium injection pipe or air compressor in the arrival end of medium injection pipe；
The pressure sensor 8, temperature sensor 9 and pressure gauge 10, flowmeter 11 are connect with monitoring system.The partition 7 is annulus
Plate, it is hollow to ensure flow of media.The effect of partition is, moves forward when 2# connecting tube 5b opens pressurization push 2# pipe cleaner 3b
When, prevent 1# pipe cleaner 3a mobile to ellipse head direction, in case 1# valve 6a can not push 1# pipe cleaner 3a when opening pressurization.
The pipe cleaner that the utility model uses commercially available can obtain for rubber cup pipe cleaner.
The pressure text head of the utility model uses ellipse head, and stress is good, when media impingement end socket, can be reduced active force
And it is whirled up.
Using the utility model carry out pipeline pressure test when, as shown in Fig. 2, by the pressure testing pipe front end of the utility model with wait try
Pressure pipe 12 is using being welded to connect, by the external high-pressure hydraulic pump of medium injection pipe.It is by pressure sensor 8 and pressure gauge 10 and monitoring
The automatic pressure recorder of system connects, and temperature sensor 9 is connect with the automatic temperature recorder of monitoring system, by flowmeter 11
It is connect with monitoring system.Water pipe pressure testing process is monitored, pressure testing is verified by the pressure volume diagram of monitoring system drafting
As a result.
To be arranged on pressure testing water pipe 12 to pressure testing siphon pressure table 13, tail portion setting annular shape is to pressure testing water pipe partition
17, drainpipe 14 is connected to pressure testing water pipe partition rear portion and exhaust-valve 15 is set, and tail end is welded to pressure testing water pipe ellipse plug 16.
It is terminal pressure table to pressure testing siphon pressure table 17, shows reference value of the pressure as pressure testing.
Pressure testing process is as follows:
A. it is first turned on 2# valve 6b, starting high-pressure hydraulic pump draws water, makes to be full of between 1# pipe cleaner 3a and 2# pipe cleaner 3b
Water is then shut off 2# valve.
B. 3# valve is opened, makes the flushing water of 100 meters or 25 cubic metres of injection in the pressure testing pipe of the front 2# pipe cleaner 3b, so
3# valve is closed afterwards.
C. the water filling of 2# valve is opened, the water of injection is made to push the water in 2# pipe cleaner 3b and pressure testing pipe towards to pressure testing water pipe 12
Direction moves ahead, and while pressing to pressure testing water pipe 12, and reach water filling, had not only rinsed pressure testing pipe but also had eliminated the sky in pipeline section
Gas.Air is discharged by opening exhaust-valve 15 in pipeline section, after 15 overflow of exhaust-valve water outlet, is closed exhaust-valve, is continued to fill the water.
During pressure testing, whether 2# valve and 3# valve while can be opened to adjust, when water filling is not stranded according to the pressure condition of pressure gauge
When difficult and pressure is not high, 2# valve and 3# valve can be opened simultaneously, should be noted that palpus confirmation 2# pipe cleaner 3b is when opening 3# valve
It moves backward and crosses at 3# valve.During filling the water pressure testing, monitoring system records pressure testing overall process pressure sensor in real time
8, the data and situation of change of pressure gauge 10, temperature sensor 9, flowmeter 11, water injection time under accurate recording, water injection pressure,
Volume, water temperature are filled the water, time, temperature, the whole uninterrupted recording of three parameter of pressure realization and formation pressure-during pressure testing are made
Capacity curve figure, more comprehensively, record result is more accurate for record data, can read the pressure and temperature value of any point-in-time, obtain
To accurate believable pressure testing result.During pressure testing, to monitor water injection rate at any time, so as to calculate 2# pipe cleaner walked it is more
Far.
D. after pressure testing water pipe 12 fills the water and test of boosting is completed and pressure release, high-pressure hydraulic pump is dismantled, by medium injection pipe
External air compressor pushes 1# pipe cleaner 3a by opening 1# valve 6a and compressed air being added, will be in pressure testing water pipe
Leave water release.Water is left to be discharged by drainpipe 14.
It can be one section of horizontal straight tube to pressure testing water pipe 12, be also possible to climbing type or descending formula inclined tube, or more
The water pipe that section connects, pressure-measuring method are all identical.
