Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the sectional view of Fig. 1.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: iron core 1, coil 11, bearing 20, fixing semi-circular plate 21, rotation semi-circular plate 22, rotating shaft 3, magnet 31, wear-resistant seal circle 32, pipeline 4.
Embodiment is substantially as shown in Figure 1, 2:
Electromagnetic cut-off valve for gas pipeline, comprise be positioned at coil outside pipeline and by coil around iron core, coil can make iron core produce magnetic field on iron core, also comprise the fixing semi-circular plate be fixed on inner-walls of duct, rotating shaft, is embedded in the magnet of the bar shaped in rotating shaft, and magnet can under the iron core effect being wound with coil, drive axis of rotation, and then drive rotation semi-circular plate to rotate closedown gas pipeline; Be fixed on the rotation semi-circular plate in rotating shaft, fixing semi-circular plate is spaced two, rotating shaft is between two fixing semi-circular plates, rotating shaft runs through rotates semi-circular plate and is rotatably connected on fixing semi-circular plate, rotate semi-circular plate and be also two, be close to a fixing semi-circular plate respectively, can control to close gas pipeline from two positions as required; Rotating shaft and fixing semi-circular plate are fixed by bearing, and fixing semi-circular plate is provided with bearings mounted groove, and bearing reduces fixing friction between semi-circular plate and rotating shaft; Rotating shaft and rotation semi-circular plate are connected and fixed by key, rotating shaft and rotation semi-circular plate are fixed, and rotating shaft is provided with seal ring with rotation semi-circular plate joint; The one end of rotating semi-circular plate size large is provided with Stamping Steel Ribbon, can prevent combustion gas from rotating the gap passing through to rotate semi-circular plate and fixing semi-circular plate after semi-circular plate closes gas pipeline.
During work, when needing to close gas pipeline, in coil, pass into electric current, iron core produces magnetic field, acts on magnet, thus drives axis of rotation, and then makes rotation semi-circular plate close gas pipeline; When needing to open gas pipeline, oppositely pass into electric current to coil, iron core produces reverse magnetic field, acts on magnet, thus drives rotating shaft to rotate backward, and then makes rotation semi-circular plate open gas pipeline.
