Description
Technical field
The present invention relates to the voltage adjusting device technical field, be specifically related to a kind of rock gas regulator.
Background technique
Because used compressed natural gas one CNG of gas-fueled vehicles is mostly supplied by the CNG gas station.Come in the rock gas of pipeline, before getting into compressor, its pressure because of ground, because of the time different, they possibly change between 0.15MPa～7MPa.Pressure is 3MPa～7MPa near major trunk roads; Arterial highway internal pressure before the urban gate station is 0.8MPa～3.0MPa; Pressure in the urban pipe network is 0.15MPa-0.6MPa.For example pressure is 3.0MPa winter in the Xi'an arterial highway, and then be 1.1MPa summer; And for example the pressure in urban pipe network changes between 0.25MPa-0.72MPa throughout the year, therefore requires the pressurizing system of gas station can be at any time, this variation of adaptation everywhere.The manufacturing enterprise of some gas station compressors gets an average pressure value and designs compressor, when pressure surpasses mean value, adopts the way of throttling to reduce pressure, so just can waste useful energy; When the pressure subaverage, compressor can move, but air demand just can reduce.Thus, make the user of gas station always feel dissatisfied.To confirm to stablize air feed when in addition, gas station being designed and power consumption also produces difficulty.Be warm in getting into the downstream using process, often need decompression, buffering, separate and metering, traditional voltage adjusting device complex structure, using effect is not good, can not stable, safe low-pressure gas source be provided for the user.
Summary of the invention
It is a kind of safe in utilization that technical problem to be solved by this invention is to provide, the rock gas regulator of working stability.
Technical problem to be solved by this invention adopts following technological scheme to realize:
A kind of rock gas regulator; Comprise the installation underframe, said installation underframe is provided with the insulation shelter, is provided with air pipe parts and electric controling part in the said insulation shelter; Described air pipe parts are connected with the blowoff line parts; It is characterized in that: described air pipe parts comprise main line, and the pressurized gas in the suction port of said main line and the rock gas tank car unload the gas flexible pipe and are connected, and are provided with one-level pressure regulator valve, secondary pressure regulator valve, three grades of pressure regulator valves and flowmeter on the described main line successively; Be provided with one-level separation buffer jar between described secondary pressure regulator valve and three grades of pressure regulator valves; Be provided with secondary separation buffer jar between described three grades of pressure regulator valves and the flowmeter, described flowmeter one end is connected with main line, and the other end is connected to air taking port.
Described blowoff line parts comprise drain pipe, and described drain pipe one end is connected with secondary separation buffer jar with one-level separation buffer jar respectively, and the said drain pipe the other end is connected to total sewage discharge outlet.
Described flowmeter is provided with one at least.
The invention has the beneficial effects as follows: the present invention is simple in structure, and working stability is reliable, can liquid and the impurity that the I and II surge separator is separated be caused user's appointment place discharging through blowoff line, and can continuous data be provided for downstream usefulness gas.

Fig. 2 is air pipe member principle figure of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of rock gas regulator comprises underframe 2 is installed, and underframe 2 is installed is provided with insulation shelter 1, is provided with air pipe parts 3 and electric controling part 4 in the insulation shelter 1, air pipe parts 3 be connected with blowoff line parts 5 as; Shown in Figure 2; Air pipe parts 3 comprise main line 37, and the pressurized gas in the suction port of main line 37 and the rock gas tank car unload the gas flexible pipe and are connected, and are provided with one-level pressure regulator valve 30, secondary pressure regulator valve 31, three grades of pressure regulator valves 32 and flowmeters 35 on the main line 37 successively; Be provided with one-level separation buffer jar 33 between secondary pressure regulator valve 31 and three grades of pressure regulator valves 32; Be provided with secondary separation buffer jar 34 between three grades of pressure regulator valves 32 and the flowmeter 35, flowmeter 35 1 ends are connected with main line 37, and the other end is connected to air taking port 36; Blowoff line parts 5 comprise drain pipe 50; Drain pipe 50 1 ends are connected with secondary separation buffer jar 34 with one-level separation buffer jar 33 respectively, and drain pipe 50 the other ends are connected to total sewage discharge outlet 51, and flowmeter 35 can be provided with a plurality of as required.
The gas flexible pipe that unloads of rock gas tank car is connected with the quick release coupling of equipment, after three grades of decompressions, gas pressure is reduced to 0.3MPa.At first high-pressure natural gas is through the decompression of I and II depressurized system; After the decompression through first-level buffer separator steady pressure (simultaneously contained humidity in the gas and impurity being separated); Measure through flowmeter then; Last gas gets into three grades of depressurized systems, and three post-decompression gases are once more through level 2 buffering separator steady pressure, and the low pressure natural gas with pressure and stable components offers custom system at last.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
