Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1 and Fig. 2, preferred embodiment for the utility model vacuum drying furnace valve, this vacuum drying furnace valve comprises valve body part 1, spool part 2 and drive the drive part 3 that described spool part 2 moves reciprocatingly in described valve body part 1, below above-mentioned each constituent element is further described in detail respectively.
Please in conjunction with reference Fig. 3 to Fig. 6, described spool part 2 comprises left valve plate 11, right valve plate 12 and between described left and right valve plate 11,12 and the middle valve plate 13 that driven by described drive part 3.Described left and right valve plate inboard connects left and right spring sheet 10L, 10R (please refer to Fig. 6) respectively.In the present embodiment, the quantity of described left and right spring sheet is 2, and the upper and lower end of described left and right spring sheet 10L, 10R all exceeds described middle valve plate 13, and the upper and lower end of relative left and right spring sheet all is fixedly connected at together.The position of described left and right valve plate 11,12 inboard corresponding described left spring sheets, right spring sheet is provided with the reed groove, and described left spring sheet, right spring sheet are fixed in the reed groove on the described left and right valve plate inboard by two screws respectively.
Please refer to Fig. 2, Fig. 3 and Fig. 5, described middle valve plate 13 is provided with a plurality of steel balls hole, and described a plurality of steel balls are respectively equipped with steel ball 131 in the hole, is respectively equipped with groove 14 in the position of the corresponding described steel ball of described left and right valve plate.Like this, when steel ball 131 is positioned at groove 14, left and right valve plate 11,12 adjacent to each other under the effect of left and right spring sheet 10L, 10R, valve is in opening state.And when steel ball 131 broke away from groove 14, left and right valve plate 11,12 was compressed by steel ball 131, and valve is in closed condition.
In the present embodiment, being shaped as of described groove 14 becomes PERICARPIUM LAGENARIAE shape big and that deepen from top to bottom gradually.This structure makes that combination and the separating action between steel ball 131 and the groove 14 is more steady, thereby makes the switch motion of valve more smooth and easy, soft, the noise when also having reduced valve switch.
Please again in conjunction with Fig. 1 and Fig. 2, described left and right valve plate and middle valve plate are all rectangular, and described steel ball hole evenly is arranged on the position near valve plate edge in described.In the present embodiment, be provided with 16 grooves 14 respectively along left and right valve plate periphery, this setup has guaranteed the reliability of valve working.
In order to alleviate the weight of valve, on described left and right valve plate 11,12, described a plurality of grooves 14 are provided with hollow structure 15 in the zone defined.
In order to realize the cooperation of spool part and valve body part, described upper and lower strut end is respectively equipped with can be at first roller of the inboard upper and lower slip of described valve body part.And corresponding described in the fixed-site of 13 4 jiaos of valve plates four second rollers are arranged, the axis of described first, second roller is orthogonal.Like this, just realized spool location partly from mutually perpendicular both direction.
Please refer to Fig. 1, described valve body part is rectangular, and described drive part 3 is located by the top of described valve body part, and comprises the linkage mechanism 32 that drives cylinder 31, is subjected to described driving air cylinder driven.Described upper support bar 16 extends upward a ledge arrangement, and the lower end of described linkage mechanism and described ledge arrangement articulate.
The working procedure of present embodiment is such, and when driving the downward drive link mechanism 32 of cylinder 31, described first, second roller just partly rolls along described valve body, moves downward thereby drive described spool part 2.When spool part 2 moves downward when touching described valve body part bottom to described left and right valve plate 11,12, left and right valve plate 11,12 namely stops to move downward.And owing to drive the thrust that cylinder 31 continues to apply, valve plate 13 can continue to move downward in described, and steel ball 131 can break away from groove 14 gradually, and described left and right valve plate 11,12 is strutted, left and right valve plate 11,12 is pressed to the opening of casing to be sealed, reach sealing effect.And the meeting that is fixed on left and right spring sheet 10L, 10R on the left and right valve plate 11,12 produces resiliently deformable.
When described driving cylinder 31 upwards spurs drive link mechanism 32 because left and right valve plate 11,12 with the rubbing action of the opening of seal case, described middle valve plate 13 can move up earlier.Steel ball 131 can progress into groove 14, and left and right valve plate 11,12 is drawn close mutually under the elastic force effect of left and right spring sheet 10L, 10R, and breaks away from the opening of seal case, whole spool part moves upward under described drive part together, thereby has realized the unlatching of valve.
Please refer to Fig. 7, the utility model also provides a kind of vacuum drying furnace, described vacuum drying furnace comprises airtight casing 4, the vacuum pump group that is connected with described airtight casing with opening, the heating system that is used to described airtight casing heating and control unit etc., also comprise the vacuum drying furnace valve V that is positioned at described airtight casing aperture position, described vacuum drying furnace valve has the structure of above-mentioned vacuum drying furnace valve, at this, do not do and give unnecessary details.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
