Description
(1) technical field
The present invention relates to rock gas station voltage adjusting device, particularly a kind of rock gas high-voltage regulator self-pressure device that is provided with emergency line.
(2) background technique
Big flow rock gas high-voltage regulator utilizes external source of the gas or instrument wind as the work source of the gas of high-voltage regulator usually, when external source of the gas and instrument wind normally during air feed high-voltage regulator can't work, cause the Natural gas letdown station room can't be to the outside ductwork air feed.Therefore we have developed a kind of rock gas high-voltage regulator self-pressure device, and this device does not need to rely on any external source of the gas and instrument wind can finish pressure regulation work, obtains good result.But still have deficiency in actual use, when namely the self-pressure pressure governor broke down in use for some time, equipment just can't normally move, and need quit work to carry out maintain and replace again, brought influence to ordinary production.
(3) summary of the invention
The objective of the invention is at above-mentioned existing problems, a kind of rock gas high-voltage regulator self-pressure device that is provided with emergency line is provided, this apparatus structure is simple, easy to implement, easy to maintenance, can guarantee the normal operation of system's air feed and safe and reliable.
Technological scheme of the present invention:
A kind of rock gas high-voltage regulator self-pressure device that is provided with emergency line, comprise natural gas supply pipeline and self-pressure pipeline, the natural gas supply pipeline comprises the rock gas import, inlet valve, heat exchanger, filter, pneumatic cut-off valve, the one-level air vent valve, the secondary pressure regulator valve, reducer union, outlet valve and gas outlet are also connected by pipeline, the natural gas supply pipeline is entering heat exchanger respectively for twice and is passing through the coil pipe heat exchange between inlet valve and the filter and between one-level air vent valve and the secondary pressure regulator valve, the self-pressure pipeline comprises the self-pressure inlet valve, self-pressure pressure regulator valve and self-pressure outlet valve are also connected by pipeline, the rock gas import of the inlet pipeline of self-pressure inlet valve and natural gas supply system and the pipeline between the inlet valve are connected, the outlet conduit of self-pressure outlet valve is partly connected with the pneumatic control of the pneumatic cut-off valve of natural gas supply system and one-level air vent valve respectively and as pneumatic source, it is characterized in that: connecting between the self-pressure outlet valve outlet conduit of the outlet valve of natural gas supply pipeline and the pipeline between the gas outlet and self-pressure pipeline has emergency line, emergency line to be provided with the self-pressure emergency valve.
Working principle of the present invention:
This device is when normal operation, and the self-pressure emergency valve of emergency line is in closed condition, and the pneumatic control part of the pneumatic cut-off valve of natural gas supply system and one-level air vent valve is respectively with the outlet conduit connection of self-pressure outlet valve and as pneumatic source.When the self-pressure pressure regulator valve of self-pressure pipeline breaks down, close self-pressure inlet valve and self-pressure outlet valve and open the self-pressure emergency valve simultaneously, the pneumatic control part that makes the pneumatic cut-off valve of natural gas supply system and one-level air vent valve respectively and the pipeline between outlet valve and the gas outlet connect, the system air feed of making is normally operation still.Can carry out maintain and replace this moment at the normal self-pressure pressure regulator valve to the self-pressure pipeline in service of system's air feed, recovers the original system operation after pending fault is finished dealing with again.
The pressure range that this self-pressure device is suitable for is: inlet pressure (4.0-20) MPa; Outlet pressure (0.2-0.6) MPa.
Advantage of the present invention is: this apparatus structure is simple, easy to implement, easy to maintenance, can guarantee the normal operation of system's air feed and safe and reliable, can be widely used in door station, industrial park station and the residential quarter station in large-scale gas company, city.
