The specific embodiment
Fig. 1 is the scheme drawing that comprises the fuel system 100 of the fuel limit connection for bbreather pipe (FLVV) 102 as double shut-off refueling valve of the present invention.System 100 comprises Fuel Tank 103 and filler pipe 104, and filler pipe 104 has and is designed to around fuel oil atomizer (not shown) leak free sealing member 106.Recirculating line 108 is connected to filler pipe 104 with Fuel Tank 103 so that from the fuel vapo(u)r recirculation of Fuel Tank 103, and tube jar pipeline 110 is connected to Fuel Tank 103 the tube jar (not shown) that stores the excess of fuel steam.The end of recirculating line 108 and tube jar pipeline 110 feeds in the Fuel Tank 103, and FLVV 102 is arranged to close simultaneously described two pipelines and transfers to another pipeline to prevent liquid fuel from a pipeline.Closing FLVV 102 produces in recirculating line 108 and sets up vacuum and impel fuel oil atomizer to turn-off.This will make the fuel vapor pressure in the Fuel Tank 103 increase, if mechanical sealing member leaks, and perhaps when being used to not have the conventional fuel system of mechanical seal structure, the fuel cut-off that this can cause pressure to order about.System 100 also can comprise the connection for bbreather pipe 112 that is connected to tube jar pipeline 110, but this valve 112 is not a part of the present invention.
Fig. 1 to 5 illustrates the configuration of system 100, wherein recirculating line 108 and tube jar pipeline 110 concentric arrangement.Although jar pipeline 110 of tube shown in the figure is configured in the outside of recirculating line 108, recirculating line 108 is also configurable in the outside of tube jar pipeline 110, and FLVV 102 is suitable for blinding off a line 108,110 and can not depart from the scope of the present invention.It should be noted that and a recirculating line 108 and a tube jar pipeline 110 also can adjoin configuration each other (for example, as shown in Figure 6), and FLVV 102 is suitable for closing these pipelines and can depart from the scope of the present invention.
Fig. 2 to 4 illustrates FLVV 102 according to an embodiment of the invention.In this embodiment, FLVV 102 has the co-axial seal configuration.FLVV 102 comprises the tubular shell 120 around float 122, and float 122 is by elastomeric element 124 (for example spring) bias voltage.Lid 126 is as the top closure member of housing 120.In one embodiment, housing 120 has a plurality of notches 128 that engage with a plurality of protrusions 130 that form around lid 126.Also can use other method that described lid is attached on the described housing.
In this embodiment, lid 126 has one or more first openings 132, and described one or more first openings 132 are around the pipe 134 with second opening 136, thus the formation coaxial configuration.First opening 132 is formed on from first ring 138 of the end face projection of described lid.First ring 138 comprises first groove 140 of first sealing member 142 of maintenance such as seal with O ring spare.Pipe 134 extends beyond first ring 138 and has second sealing member 144 around second opening 136 as seal with O ring spare.On pipe 134, can be formed with lip 146 to support second sealing member 144.The inside of FLVV 102 can be any known float valve configuration in this embodiment.
