Referring to accompanying drawing 3, compile pipeline 4 and comprise six pressure gauges 9, left pneumatic tube 10, two thermometers 11, two safety valves 12, ten normally-closed ball valve 13, right pneumatic tube 14, relief tube 15, four-way 16, quick union 17, main pneumatic tube 18, compile pipeline 4 and be divided into left pneumatic tube 10, right pneumatic tube 14, relief tube 15,17 4 pipelines of main pneumatic tube by four-way 16, four normally-closed ball valve 13 are spirally connected respectively on four interfaces of four-way 16.
Be connected a thermometer 11 respectively on a left side pneumatic tube 10 and the right pneumatic tube 14, six branch road five equilibriums that equate with six groups of boundling pipeline 1 quantity are connected on left pneumatic tube 10 and the right pneumatic tube 14, each branch road connects a pressure gauge 9 and a normally-closed ball valve 13, two safety valves 12 are connected to the upper end of left pneumatic tube 10 and right pneumatic tube 14, pressure gauge 9, thermometer 11 plays monitors effect in real time to gas pressure that compiles pipeline and temperature, compile the gas pressure of pipeline when excessive, safety valve 12 is opened in good time, carry out pressure release, as urgency, can open the normally-closed ball valve 13 on the relief tube 15, realize quick pressure releasing.
Main pneumatic tube 18 is connected on the normally-closed ball valve 13 of four-way 16 lower interfaces, and quick union 17 is connected in the lower end of main pneumatic tube 18, and relief tube 15 is connected on the normally-closed ball valve 13 of interface on the four-way 16.
Six groups of boundling pipelines, the 1 corresponding six roots of sensation connecting tube 3 of pipe-line system, and two unions by connecting tube 3 two ends 2 and compile pipeline 4 and be communicated with, simultaneously, boundling pipeline 1 and compile pipeline 4 and can realize fast assembling-disassembling by union 2.
Working procedure:
During the pipe-line system inflation, close and be connected in the normally-closed ball valve on the interface relief tube 15 13 on the four-way 16, open the normally-closed ball valve 13 that is connected on the four-way 16 lower interface master pneumatic tubes 18, quick union 17 inserts source of the gas, and compressed natural gas charges into by quick union 17.
As need six groups of boundling pipelines 1 of left pneumatic tube 10 and right pneumatic tube 14 are inflated simultaneously, open two normally-closed ball valve 13 that are connected on the four-way 16 left and right interfaces simultaneously, simultaneously, open the cylinder valve 6 on each air cylinder 5 on six normally-closed ball valve 13 compiling on 4 six branch roads of pipeline and the six groups of boundling pipelines 1, can inflate this moment to each air cylinder 5 on six groups of boundling pipelines 1, and monitor in real time by pressure gauge 9,11 pairs of gas pressures of thermometer and temperature.
As only needing three groups of boundling pipelines 1 of left pneumatic tube 10 or 14 connections of right pneumatic tube are inflated, open one that is connected on the four-way 16 left and right interfaces in two normally-closed ball valve 13 this moment, close another, simultaneously, open the cylinder valve 6 on each air cylinder 5 on three normally-closed ball valve 13 compiling on pipeline 4 corresponding three branch roads and the three groups of boundling pipelines 1, can inflate each air cylinder 5 on three groups of boundling pipelines 1.
As only needing single group boundling pipeline 1 of left pneumatic tube 10 or 14 connections of right pneumatic tube is inflated, open one that is connected on the four-way 16 left and right interfaces in two normally-closed ball valve 13 this moment, close another, simultaneously, open the cylinder valve 6 on each air cylinder 5 on a normally-closed ball valve 13 of compiling on the pipeline 4 corresponding branch roads and the one group of boundling pipeline 1 that needs inflation, can inflate each air cylinder 5 on single group boundling pipeline 1.
And the like, by controlling the cylinder valve 6 on corresponding normally-closed ball valve 13 and the air cylinder 5, can realize single or multiple air cylinders 5 are inflated.
During the pipe-line system venting, close the normally-closed ball valve 13 on the relief tube 15, open the normally-closed ball valve 13 that is connected on the four-way 16 lower interface master pneumatic tubes 18, compressed natural gas is emitted by quick union 17.
By controlling the opening and closing of the cylinder valve 6 on corresponding normally-closed ball valve 13 and the air cylinder 5, the three groups of boundling pipelines 1 or the single group boundling pipeline 1 that can realize that six groups of boundling pipelines 1 are exitted simultaneously, left pneumatic tube 10 or right pneumatic tube 14 connect are exitted, and also can realize single or multiple air cylinders 5 are exitted simultaneously.
