Embodiment
As shown in Figure 1, in the preferred embodiment of high-temperature gas changing-over valve described in the utility model, comprise support 10, control motor 1, live axle 2 and be arranged on the driving mechanism of controlling between motor 1 and the live axle 2.Wherein, the lower end of live axle 2 can be rotated thereby make live axle 2 can drive rotatingshaft 4 by the rotatingshaft 4 shaft coupling settings of coupling 3 with high-temperature gas changing-over valve.Support 10 comprises three heat reflection plates: go up reflecting plate 21, following reflecting plate 23 and middle reflecting plate 22, and the pillar 30 that is provided with between the heat reflection plate.Following reflecting plate 23 can be fixed on the valve body 6 of high-temperature gas changing-over valve by screw 5, is fixed together by pillar 30 between the heat reflection plate, and control motor 1 is fixedly installed on the reflecting plate 21.Pillar 30 preferably segmented settings, adopt first pillar 31 to be fixed together between last reflecting plate 21 and the middle reflecting plate 22, be fixed together by second pillar 32 between middle reflecting plate 22 and the following reflecting plate 23, promptly go up between reflecting plate 21 and the middle reflecting plate 22 and middle reflecting plate 22 and following reflecting plate 23 between pillar be different pillars, avoided like this that heat directly is delivered to reflecting plate 21 by pillar 30 when not segmentation is provided with, reduced of the influence of the heat of high-temperature gas control motor 1.Heat reflection plate can be made with corrosion resistant plate or chromium plating, nickel plating, galvanized steel plain sheet, present embodiment preferably adopts aluminum alloy material to make, because aluminum alloy material rapid heat dissipation, the air around thereby the heat that passes over from valve body can being radiated rapidly, by the air flows at interval between the heat radiation plate heat is taken away again; Simultaneously, the high finishingness on aluminium alloy plate surface is easier to realization, thereby most of reflect heat of coming by thermal radiation from valve body can be gone back, and the heat direct radiation that has intercepted valve body is to control motor 1, thus protection control motor 1.
On above-mentioned heat reflection plate, offer through hole 71, live axle 2 is passed through hole 24 and make the upper end of live axle 2 between last reflecting plate 21 and middle reflecting plate 22.Between the output shaft 7 of live axle 2 and control motor, also be provided with driving mechanism, make control motor 1 can drive live axle 2 and rotate.Particularly shown in Fig. 2,5, this driving mechanism can be set comprise shift fork 41 and crank 42, shift fork 41 is fixed in the rotating shaft 43 of driven in parallel axle 2 axis, and rotating shaft 43 is driven by control motor 1 and rotates, and the lower end that rotating shaft 43 is set extends between reflecting plate 21 and the middle reflecting plate 22; One end of crank 42 is fixed on the upper end of live axle 2, and the other end matches with the tail end of shift fork 41, and this crank 42 is also between last reflecting plate 21 and middle reflecting plate 22.In this preferred embodiment, preferably on crank 42, a pusher dog 44 with live axle 2 parallel axes is set with the corresponding position of shift fork 41 tail ends, at the tail end of shift fork 41 U-groove bevel 45 is set, pusher dog 44 stretches in U-groove bevel 45.When control motor 1 drove shift fork 41 43 rotations around the shaft, the U-groove bevel 45 that is positioned at shift fork 41 tail ends drove the pusher dog 44 that drives and moves, and make crank 42 can drive live axle 2 and rotate, thereby control valve was opened or was closed.Because pusher dog 44 is the line contact when being stirred by U-groove bevel 45, therefore, the heat that directly transmits by transmission of heat is very little between the two, thereby has further reduced the heat that passes to control motor 1.In addition, the drive mechanism of shift fork 41 and crank 42, prolonged in valve body 6 and transmitted the thermal conduction of heat route, avoided when the output shaft 7 of control motor directly drives the rotatingshaft 4 of high-temperature gas changing-over valve, heat directly is delivered on the control motor 1 from rotatingshaft 4, the control accuracy and the life-span of influence control motor 1.And crank 42 and shift fork 41 are between last reflecting plate 21 and middle reflecting plate 22, and its most of thermal radiation can further have been reduced the heat that is delivered to control motor 1 by last reflecting plate 21 reflections.In this preferred embodiment, described pusher dog 44 also can be arranged on the tail end of shift fork 41, and with pusher dog 44 corresponding ends above-mentioned U-groove bevel 45 is set on crank 42, can achieve the above object equally.
As shown in Figure 1, be provided with turbine and worm mechanism 50 between the rotating shaft 43 of control motor output shaft 7 and shift fork,, realize slowing down by this turbine and worm mechanism 50 is set, reduced the rotating speed that inputs to rotating shaft 43 from control motor output shaft 7, conveniently valve has accurately been controlled.
Second lining made from thermoinsulation material 60 preferably is set between pillar 30 and heat reflection plate, makes as heat resistant plastice.As shown in Figure 3, heat reflection plate is fixed on the end of pillar 30 by screw 61, on screw, be arranged with second lining 60 of T shape, this second lining 60 is embedded in the through hole 62 that is provided with on following reflecting plate 23, again screw 61 is passed the center hole 63 that is provided with in the middle of second lining, thereby screw 61 and following reflecting plate 23 thermal insulation are opened.Also can packing ring 64 be set at the tail end of second lining 60, be used for pillar 30 and following reflecting plate 23 thermal insulation are opened.Thereby further reduced the direct heat conduction between pillar 30 and the heat reflection plate.
As shown in Figure 4, following reflecting plate 23 and middle reflecting plate 22 are provided with the through hole 71 that passes for live axle 2, and the 3rd lining 70 that thermoinsulation material is made preferably is set between live axle 2 and heat reflection plate 23,22.The 3rd lining 70 is set to T shape, and its center is provided with center hole 72, and its tail end is provided with draw-in groove 73.After the 3rd lining 70 passes through hole 71 on the described heat reflection plate, snap in the draw-in groove 73 with snap ring 74, thereby the 3rd lining 70 is fixed in the through hole 71 of heat reflection plate, again live axle 2 is passed the center hole 72 of the 3rd lining, also can be on the heat reflection plate 22 thereby live axle 2 is fixed on around the central axis rotation of self.Because the 3rd lining 70 is arranged between live axle 2 and the reflecting plate through hole, makes live axle 2 be spaced apart and directly not contact with heat reflection plate 22, thereby further reduced live axle 2 heat is passed to heat reflection plate 22 by heat conducting mode.
Equally, first lining of being made by thermoinsulation material 80 also can be set, as shown in Figure 4 between live axle 2 upper ends and crank 42.This end that crank 42 is fixed on the live axle 2 is provided with a tapped hole 81, and the upper end of live axle 2 is provided with a flat position 82.First lining, 80 outsides are provided with the outside thread that is complementary with tapped hole 81, and its inboard is provided with the hole 83, flat position of matching with the flat position 82 of live axle.First lining 80 is fixed on by screw thread in the tapped hole 81 of crank, again the hole 83, flat position of first lining is set in the flat position 82 of live axle, thereby crank 42 is fixed on the upper end of live axle 2.Because crank 42 directly contact with live axle 2, between the two between across first lining 80, make and reduce by the heat that heat exchange pattern is delivered to crank 42, thereby further reduced controlling the influence of motor 1 from live axle 2.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
