Abstract
The utility model relates to a valve plate supports for push -pull valve, characterized by: be equipped with the hole in the valve plate supporting, the inner wall shape size that the hole was fought with last transition and lower transition is fought unanimously, the both sides limit of hole sets up first support bar and second support bar respectively, sets up the third support bar at the third side of hole, the length of first support bar and second support bar is less than the length of hole, and first support bar and second support the other end that is extended to hole length direction by hole length direction one end to there is the clearance between first support bar and second support bar and the hole third side. The hole of valve plate supporting is the rectangle. The length of third support bar is less than the width of hole. A valve plate supports for push -pull valve, can avoid the pollution of picture peg and valve plate when contact supporting defective material, guarantee the in proper working order of push -pull valve.
Description
Technical field
The utility model relates to a kind of disc support for push-pull valve, belongs to field of mechanical technique.
Background technique
In prior art, the structure of push-pull valve is general as shown in Figure 1, between upper transition bucket 1 and lower transition bucket 4, valve body 5 is set, plate 2 is set in valve body 5, plate 2 is realized pulling by pull lever 6, plate 2 is arranged in valve plate supporting 3, supports plate plate 2 can be moved along plugboard trough 7 by valve plate supporting 3, to realize the action of the round mouth opening and closing in valve plate supporting 3.In general technology, valve plate supporting 3 is all offer round mouth (as shown in Figure 2), and the inner surface contour of upper transition bucket 1 and lower transition bucket 4 adopts rectangular configuration at present, thus cause the defective material on the surface of contact of plate 2 and valve plate supporting 3 can pollute plate 2, bring plugboard trough 7 into by plate 2 again and pollute pull lever 6 device, cause plate normally to work.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of disc support for push-pull valve, avoids the pollution of defective material when plate and valve plate bearing contact, ensures the working properly of push-pull valve.
According to the technological scheme that the utility model provides, the described disc support for push-pull valve, is characterized in that: described valve plate supporting is provided with endoporus, and the inner wall shape of endoporus and upper transition bucket and lower transition bucket is in the same size; First supporting bar and the second supporting bar are set respectively at the dual-side of described endoporus, the 3rd supporting bar is set at the 3rd side of endoporus; The length of described first supporting bar and the second supporting bar is less than the length of endoporus, first supporting bar and second supports the other end being extended to endoporus length direction by endoporus length direction one end, and the first supporting bar and there is gap between the second supporting bar and endoporus the 3rd side.
Further, the endoporus of described valve plate supporting is rectangular.
Further, the length of described 3rd supporting bar is less than the width of endoporus.
Disc support for push-pull valve described in the utility model, can avoid the pollution of defective material when plate and valve plate bearing contact, ensures the working properly of push-pull valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of described push-pull valve.
Fig. 2 is the structural representation of existing valve plate supporting.
Fig. 3 is the structural representation of valve plate described in the utility model supporting.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 3: the described disc support for push-pull valve comprises valve plate supporting 3, endoporus 8, first supporting bar 9, second supporting bar 10, the 3rd supporting bar 11, gap A etc.
As indicated at 3, valve plate supporting 3 described in the utility model is provided with endoporus 8, endoporus 8 is in the same size with the inner wall shape of upper transition bucket 1 and lower transition bucket 4, the endoporus 8 of valve plate supporting 3 is rectangular, the both sides corresponding to plate 2 insertion end in the both sides of endoporus 8 arrange the first supporting bar 9 and the second supporting bar 10 respectively, arrange the 3rd supporting bar 11 at endoporus 8 sidepiece corresponding to plate 2 insertion end; The length of described first supporting bar 9 and the second supporting bar 10 is less than the length of endoporus 8, and the length of the 3rd supporting bar 11 is less than the width of endoporus 8; Described first supporting bar 9 and second supports 10 the to be extended to endoporus 8 length direction the other end by endoporus 8 length direction one end, and the first supporting bar 9 and there is gap A between the second supporting bar 10 and endoporus 8 side residing for the 3rd supporting bar 11.Operationally, plate 2 is pulled by pull lever 6 and returns to plugboard trough 7, during to open material hole, expects to pass through by material hole; When blowing is complete, plate 2 pulls insertion material hole by pull lever 6, defective material on first supporting bar 9 and the second supporting bar 10 can be pushed into gap A by plate, fall to lower transition bucket 4, to prevent plate 2 when upper once returning in plugboard trough 7, defective material is brought in plugboard trough 7, pollute plugboard trough 7, caused push-pull valve normally to work for a long time in the past.
