The control guiding device of block pipeline gas pressure test.Belong to Offshore Engineering field.
Background technology
At present, liquefied natural gas core process module generally, is completed to build, then, then by mould in build the side sub-module
Block arrives at assembling through sea-freight.Since liquefied natural gas core process module need to be mounted on arctic Ji Han areas, it is existing
Method be that gas pressure test quantity is more, it is dangerous high, wherein, highest test pressure 13.9MPa, highest air pressure volume 230M3,
Highest air pressure energy storage 2606MJ.And since location Environment Design temperature is -40 degrees Celsius, these factors cause to pipeline drying
Requirement it is extremely stringent.The shortcomings that existing method, is mainly reflected in the following aspects：
(1) operating personnel need to enter liquefied natural gas core process module, check and are mounted on the pressure gauge that pressure testing is wrapped,
By compressor operating personnel under intercom notification module, increase the number for stopping pressure or pressure release, this is to the operating personnel in module
It is extremely dangerous.
(2) someone, personnel do not concentrate at compressor and in liquefied natural gas core process module, issue the personnel of instruction
In liquefied natural gas core process module, and boost operations personnel easily generate under liquefied natural gas core process module
Maloperation.
(3) a compressor can only once carry out the pressure testing of a pressure testing packet, less efficient.
(4) when gas pressure test finishes, the gas in air pressure packet can only discharge, and the energy therein cannot efficiently use.
Utility model content
The main purpose of the utility model is that overcome disadvantages mentioned above of the existing technology, and it is natural to provide a kind of liquefaction
The control guiding device of gas core process module pipeline gas pressure test, it is easy to operate, multiple pressure testings can not only be completed simultaneously
The work pressure test of packet solves the problems, such as and realizes multiple compressor parallel pressurizations, greatly reduces pressing time；Moreover,
Gas pressure test efficiency and the safety of liquefied natural gas core process module pipeline system are also improved, reaches energy-saving and emission-reduction, drop
The purpose of this synergy.
The purpose of this utility model is realized by following technical scheme：
A kind of control guiding device of liquefied natural gas core process module pipeline gas pressure test, it is characterised in that：Including：
One pressure testing supervisor, the inlet tube being connected on pressure testing supervisor and several branched pipes, blow-off pipe, wherein, inlet tube, each branched pipe
And welding valve, several screw thread valves, safety valve, pressure gauge, reducing pipe collar are separately installed on blow-off pipe；On several branched pipes
It is separately installed with detection pipe, outlet and pressure gauge branch pipe.
The inlet tube, several branched pipes and pressure testing are responsible for be connected by tube socket.
The beneficial effects of the utility model：The utility model is due to the adoption of the above technical scheme, easy to operate, can not only
Enough work pressure tests for completing multiple pressure testing packets simultaneously solve the problems, such as and realize multiple compressor parallel pressurizations, subtract significantly
Pressing time is lacked；Moreover, also improve the gas pressure test efficiency and safety of liquefied natural gas core process module pipeline system
Property, achieve the purpose that energy-saving and emission-reduction, cost efficiency.

Specific embodiment
As shown in Figure 1, the utility model includes：Pressure testing supervisor 7, be connected to using welding manner on pressure testing supervisor 7 into
(the present embodiment is for mouthful pipe 8 and several branched pipes：First branched pipe 9, second branched pipe 10, third branched pipe 11), blow-off pipe
15, wherein, welding valve 1, several screw thread valve (the present embodiment are separately installed on inlet tube 8, each branched pipe and blow-off pipe
For：First screw thread valve 2, the second screw thread valve 3), safety valve 4, pressure gauge 5, reducing pipe collar 6；First branched pipe 9 and second point
Detection pipe 12, outlet 13 and pressure gauge branch pipe 14 are separately installed with using welding manner on branch pipe 10.
Above-mentioned 1 and second screw thread valve 3 of welding valve mainly plays a part of to turn off and control buck speed；First screw thread
Valve 2 is located in detection pipe 12, is under normal circumstances normally off, when detecting whether string pressure, can open the first screw thread valve 2 and examine
It looks into.
Above-mentioned inlet tube 8, the first branched pipe 9, second branched pipe 10, third branched pipe 11 and pressure testing supervisor 7 pass through tube socket
It is weldingly connected；4 can effectively protect pressure testing personnel of safety valve and equipment safety, prevent superpressure；Pressure gauge 5 can real-time display experiment pressure
The state of power；Reducing pipe collar 6 mainly plays reducing, is connected with adapting to smaller size of hose.
The utility model can implement function such as：
1. the long-range monitoring of pressure testing packet, remote operation, it is ensured that in boost process, in pressure testing packet safety zone nobody into
Enter, so as to improve the safety of pressure testing operating personnel；
2. instruction issuing personnel concentrate on pressure testing device region with site operation personnel, all operations are on pressure testing device
It completes；
3. it can realize that a compressor to wrapping pressurization, improves the efficiency of gas pressure test, i.e., more：One compressor connection is originally
The pressure testing supervisor 7 of utility model by the first branch line 9 and second branched pipe line 10, can simultaneously rise two pipelines
Reduced pressure operation；
4. the air-flow between can realizing several pressure testing packets that pneumatic shuttle is connected transmits, when a packet pressure testing terminates
Afterwards, another packet can be connected by device, pressure transmission is gone over, so as to save device resource.I.e.：First branched pipe, 9 He
Transmission between third branched pipe 11；
5. for the pressure testing packet that volume is larger, multiple compressor parallel pressurizations can be realized, to reduce pressing time.I.e.：
It is in parallel by inlet tube 8, air-flow is converged into Trunk Line 7 and connects the larger pipeline of volume.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, it is every according to the technical essence of the utility model to above example made it is any it is simple modification, equivalent variations with
Modification, in the range of still falling within technical solutions of the utility model.
