Abstract
The utility model relates to an isobaric ventilation block for a CNG (Compressed Natural Gas) filling station. The isobaric ventilation block is characterized by comprising a block body which is internally provided with a ventilation channel, wherein a plurality of pipeline connectors are arranged on the block body and are communicated by the ventilation channel; and sealing pipe threads are arranged in the pipeline connectors on the block body. The isobaric ventilation block disclosed by the utility model has the advantages of simple structure, simplicity of manufacture, low cost, convenience for mounting and dismounting, small occupied space and the capabilities of simplifying a pipeline structure, beautifying the appearance of the pipeline and effectively avoiding leakage of natural gas.
Description
Technical field
The utility model relates to the CNG gas station, particularly relates to a kind of gas station with isobaric ventilation piece.
Background technique
The CNG gas station is meant the place that fuel is provided to gas-fueled vehicles and large-scale CNG substation car with the compressed natural gas form.After compressed natural gas inputs to the CNG air entraining substation by tank car, after filter, pneumatic ball valve and pressure governor, get into the I and II compression cylinder of air cylinder group, air cooler and compressor.As shown in the figure; In conventional art; Compressed natural gas utilizes gas pipeline behind filter, pneumatic ball valve and pressure governor, to be divided into three the road to converge in 1 A, and compressed natural gas is divided into the I and II compression cylinder that four road gas pipelines get into air cylinder group, air cooler and compressor respectively after the A point is delivered to the B point isobaric with it, and this part combustion gas transfer pipeline is main at present to adopt a plurality of flare type joints and threeway or the curved logical Stainless Steel Tube formation that is connected; Not only installing/dismounting is not easy, the pipeline maintenance is difficult, installation cost is high; And because need the mounting distance about 110mm between the flare type joint, so the integral body of pipeline takes up room greatly, the pipeline confusion is not attractive in appearance; Leak source increases, and causes natural gas leaking easily.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, make easily, cost is low, easy installation and removal, take up room little, can simplify pipeline structure, beautify the pipeline outward appearance, and the gas station that can effectively avoid natural gas leaking is with isobaric ventilation piece.
The utility model for the technological scheme that solves the technical problem that exists in the known technology and take is: a kind of CNG gas station is with isobaric ventilation piece; It is characterized in that: comprise that inside is provided with the block of air vent; Said block is provided with several pipeline connection mouths; Be connected through air vent between the said pipeline connection mouth, be provided with the sealed pipe screw thread in the pipeline connection mouth on the said block.
The utility model can also adopt following technological scheme:
Said block is provided with 7 pipeline connection mouths that are interconnected through air vent, and wherein three pipeline connection mouths are the rock gas suction port, and four pipeline connection mouths are the rock gas air outlet.
Said block is processed by No. 20 steel, and its block surface is zinc-plated.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technological scheme; Promptly design the equipressure ventilation piece that a kind of inside has air vent; The ventilation piece is provided with several pipeline connection mouths, and air vent constitutes the combustion gas transfer pipeline that connects each other in equipressure ventilation piece, compare the connection mode of traditional flare type joint and Stainless Steel Tube; The utility model is not only simple in structure, make easily, cost is low, easy installation and removal, take up room little; And whole linkage structure that can the simplified system pipeline makes the pipeline marshalling, the layout visual and clear.Be provided with the sealed pipe screw thread in the pipeline connection mouth, increase the sealing effect that pipeline connects, can effectively avoid natural gas leaking.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode figure of the utility model.
Among the figure: 1, block; 1-1, pipeline connection mouth; 1-2, air vent.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, the isobaric ventilation of a kind of CNG gas station usefulness piece.Comprise block 1, block 1 is provided with several pipeline connection mouths 1-1, and pipeline connection mouth 1-1 is interconnected through the air vent 1-2 of the portion of setting within it.This equipressure ventilation piece replaces flare type joint, threeway or the curved logical Stainless Steel Tube in the conventional art to be installed in the air delivering pipeline of CNG gas station; Several pipeline connection mouths 1-1 on the promptly isobaric ventilation piece respectively with the CNG gas station in air delivering pipeline be connected; Be provided with in the pipeline connection mouth 1-1 and be provided with the sealed pipe screw thread in the sealed pipe screw thread, can effectively imitate and avoid natural gas leaking.This equipressure ventilation piece compared with prior art, not only simple in structure, make easily, cost is low, easy installation and removal, take up room for a short time, and whole linkage structure that can the simplified system pipeline makes the pipeline marshalling, the layout visual and clear.The block 1 of isobaric ventilation piece is processed by No. 20 steel, and its block 1 plating zinc on surface can effectively prolong working life of isobaric ventilation piece.
Like Fig. 2, the block of above-mentioned isobaric ventilation piece is provided with 7 pipeline connection mouths, and wherein 3 pipeline connection mouths are as the rock gas suction port, and four pipeline connection mouths are the rock gas air outlet.In the CNG gas station; Compressed natural gas utilizes gas pipeline behind filter, pneumatic ball valve and pressure governor, to be divided into three the tunnel and enters into block inside from three suction ports of equipressure ventilation piece respectively; Rock gas in block inside by air vent transfer mediation back from 4 air outlets outputs, and four road gas pipelines that are connected with the air outlet of warp transfer to the I and II compression cylinder of air cylinder group, air cooler and compressor.
