Abstract
The utility model relates to a natural gas control device for compressor instrument air, which includes a pneumatic ball valve and is characterized in that the pneumatic ball valve is communicated with an energy storage tank (3) through a pipeline I, the energy storage tank (3) is communicated with a high-pressure natural gas source through a pipeline II, and a pressure reducing valve (7) is arranged on the pipeline II. The natural gas control device for compressor instrument air has the benefit of utilizing the own natural gas source to provide energy and control the natural gas instrument air, thereby greatly increasing the safety factor of a compressor unit in a gas station.
Description
Technical field
The utility model relates to a kind of compressor, especially a kind of rock gas control gear of compressor instrument wind.
Background technique
Mostly the Compressor Group of natural gas filling station is multistage compression; In order to guarantee high-quality gas, general every grade all has oily water separating equipment, after running a period of time; Need eject the greasy dirt in these equipment; Because blowdown point is many,, adopt automatic control blowdown particularly important in order to reduce operator's amount of labour and operate miss rate.Most air air pumps that adopt provide instrument wind in the industry, and with pneumatic ball valve control, this just is prone to cause air to get into the danger of gas distributing system, and rock gas belongs to inflammable and explosive medium, especially with air mixing after more dangerous.
The model utility content
The purpose of the utility model is exactly in order to overcome the existing air air pump that adopts instrument wind to be provided, and with pneumatic ball valve control, is prone to cause air to get into the defective of gas distributing system, and the rock gas control gear of a kind of compressor instrument wind that provides.
The utility model solves the technological scheme that its technical problem adopted:
The rock gas control gear of compressor instrument wind comprises pneumatic ball valve, it is characterized in that: pneumatic ball valve is communicated with energy storage canister through pipeline one, and energy storage canister is communicated with the high-pressure natural gas source through pipeline two, on pipeline two, is provided with reduction valve.
On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:
On the pipeline between energy storage canister and reduction valve two, be provided with the gas treatment triplet.
On the pipeline two between energy storage canister and gas treatment triplet, be provided with manual ball valve.
On the pipeline between energy storage canister and manual ball valve two, be provided with one-way valve.
Energy storage canister is provided with one group of blowdown pneumatic ball valve.
The beneficial effect of the utility model is that the natural air-air source of utilization own provides energy, and rock gas instrument wind is controlled, and gas station Compressor Group safety coefficient is improved greatly.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings:
Fig. 1 is the plan view of the utility model.
Embodiment
As shown in Figure 1, the rock gas control gear of the utility model compressor instrument wind comprises energy storage canister 3; Energy storage canister 3 is communicated with pneumatic ball valve 1 through pipeline one, and energy storage canister 3 is communicated with the high-pressure natural gas source through pipeline two, on pipeline two, is provided with reduction valve 7; On the pipeline two of 7 of energy storage canister 3 and reduction valve, be provided with gas treatment triplet 6; Be used for purified natural gas, on the pipeline two of 6 of energy storage canister 3 and gas treatment triplets, be provided with manual ball valve 5, pipeline two is carried out manually opened or closes; On the pipeline two of 5 of energy storage canister 3 and manual ball valves, be provided with one-way valve 4; Be used for the control gaseous one-way flow, energy storage canister 3 is provided with one group of blowdown pneumatic ball valve 2, and both connect through pipeline.
During practical implementation; Can choose knockout drum or the knock out drum of natural gas compressor group greater than 1MPa; Draw natural air-air source above that; Through reduction valve 7 decompression 0.7-0.8MPa, through gas treatment triplet 6 rock gas instrument wind is filtered oil removing once more again, the rock gas of cleaning gets into the instrument wind that energy storage canister 3 provides the control pneumatic element.In order to prevent that reduction valve 7 from use damaging, make to get into energy storage canister 3 greater than the gas of 1MPa and damage pneumatic elements, on energy storage canister 3, increased safety valve for this reason, on pipeline, increased manual ball valve 5, but hand off source of the gas when going wrong.In order to prevent to shut down in the energy storage canister 3 of back gases flow backwards back knockout drum or knock out drum, increased one-way valve 4, having guaranteed has energy in the energy storage canister 3.
Claims (5)
