Abstract
The invention relates to a gate valve. The gate valve comprises a valve body. A material through hole is formed in the valve body. The upper end of the material through hole is connected with an upper transition hopper. The lower end of the material through hole is connected with a lower transition hopper. An inserting plate and a valve plate bearing are arranged between the upper transition hopper and the lower transition hopper. The gate valve is characterized in that an inner hole is formed in the valve plate bearing, and the inner hole is consistent with the inner wall of the upper transition hopper and the inner wall of the lower transition hopper in shape and size. A first supporting strip and a second supporting strip are arranged on the parts, corresponding to the two sides of the inserting end of the inserting plate, of the two sides of the inner hole respectively, and a third supporting strip is arranged on the side portion of the part, corresponding to the inserting end of the inserting plate, of the inner hole. The length of the first supporting strip and the length of the second supporting strip are smaller than that of the inner hole. The first supporting strip and the second supporting strip extend to the other end, in the length direction, of the inner hole from one end, in the length direction, of the inner hole, and gaps exist between the first supporting strip and the side edge of the part, at the third supporting strip, of the inner hole and between the second supporting strip and the side edge of the part, at the third supporting strip, of the inner hole. Residual material pollution caused when the inserting plate makes contact with the valve plate bearing can be avoided, and normal work of the gate valve is guaranteed.
Description
Technical field
The present invention relates to a kind of push-pull valve, belong 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 object of the invention is to overcome the deficiencies in the prior art, a kind of push-pull valve is provided, avoid the pollution of defective material when plate and valve plate bearing contact, ensure the working properly of push-pull valve.
According to technological scheme provided by the invention, described push-pull valve, comprise valve body, valve body is provided with material hole, the upper end of material hole connects upper transition bucket, and the lower end of material hole connects lower transition bucket, arranges plate and valve plate supporting between upper transition bucket and lower transition bucket, plate one end is connected with pull lever, and pull lever is connected with drive unit; It is characterized in that: in described valve plate supporting, be provided with endoporus, the inner wall shape of endoporus and upper transition bucket and lower transition bucket is in the same size.
Further, the endoporus of described valve plate supporting is rectangular.
Further, the both sides corresponding to plate insertion end in the both sides of described endoporus arrange the first supporting bar and the second supporting bar respectively, arrange the 3rd supporting bar at the endoporus sidepiece corresponding to plate insertion end; 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 the endoporus side residing for the 3rd supporting bar.
Further, the length of described 3rd supporting bar is less than the width of endoporus.
Further, described pull lever is arranged in plugboard trough.
Push-pull valve of the present invention, 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 of the present invention supporting.
Embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 3: described push-pull valve comprises transition bucket 1, plate 2, valve plate supporting 3, lower transition bucket 4, valve body 5, pull lever 6, plugboard trough 7, endoporus 8, first supporting bar 9, second supporting bar 10, the 3rd supporting bar 11, gap A etc.
As shown in Figure 1, the present invention includes valve body 5, valve body 5 is provided with material hole, the upper end of material hole connects upper transition bucket 1, the lower end of material hole connects lower transition bucket 4, arrange plate 2 and valve plate supporting 3 between upper transition bucket 1 and lower transition bucket 4, plate 2 one end is connected with pull lever 6, and pull lever 6 is connected with drive unit; As shown in Figure 3, described valve plate supporting 3 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.
