The utility model discloses a pneumatic butterfly valve of dust pelletizing system, simple structure, the response has different apertures rapidly to convenient operation, it is not fragile.
Description
Technical field
The utility model relates to a kind of Pneumatic butterfly valve of dust pelletizing system, belongs to technical field of dust removal equipment.
Background technique
The fields such as the polishing of the polishing of marble of the prior art, Manmade Stone, natural stone and cutting and furniture, in processing factory building, dust in air is flown upward, and operator works in such circumstances, will have a strong impact on healthy.Therefore in processing factory building, usually sack cleaner is set.Sack cleaner is conventional a kind of dusting apparatus, such as a kind of pulsed jet cloth filter disclosed in Chinese patent literature CN101670214B.Usually the mouth of pipe of multiple sucking pipes of sack cleaner is arranged at respectively the multiple working zones in factory building, sucking pipe arranges push-pull valve, control the logical of sucking pipe by control push-pull valve and close.But push-pull valve has corresponding slow shortcoming, sealing is also poor simultaneously, often easily leaks gas when closing, and gas leakage causes poorly sealed, causes other sucking pipe air pressure to reduce; Simultaneously push-pull valve easily damages, can not control valve aperture, can only standard-sized sheet or full cut-off.
Model utility content
Therefore, the purpose of this utility model is to overcome defect of the prior art, provides a kind of response rapidly, has the Pneumatic butterfly valve of the dust pelletizing system of different opening.
To achieve these goals, the Pneumatic butterfly valve of a kind of dust pelletizing system of the present utility model, the valve plate comprising valve body, be positioned at the valve shaft on valve body and be installed on described valve shaft, a connecting rod is fixed in one end of described valve shaft, described connecting rod is connected to the cylinder arm of a cylinder, described connecting rod can be driven to drive described valve shaft to rotate by described cylinder; Described valve shaft is also provided with opening adjusting device, and described opening adjusting device comprises the annular seating fixed with valve body, and being provided with in described annular seating can the rotary part of coaxial rotating, and described rotary part is fixed on described valve shaft; On the sidewall of described annular seating, be provided with some arch shaped cavity at described rotary part, described annular seating is provided with the through hole that radial direction is offered, be provided with Compress Spring in described through hole, one end of the radial outside of each described through hole is bolted with block; One end of described Compress Spring withstands on described block, and the other end withstands an iron ball, and described iron ball withstands on described rotary part.
Described rotary part is connected by key with described valve shaft.
Described through hole is two.
Two described through holes are symmetricly set on described annular seating.
Described valve body is provided with bearing, and described valve shaft is installed on described bearing.
Adopt technique scheme, the Pneumatic butterfly valve of dust pelletizing system of the present utility model, is moved by the described connecting rod of flexible drive of cylinder arm, thus drives described valve shaft to rotate, and valve shaft rotates and valve plate is rotated, thus realizes the logical of butterfly valve and close, and responds rapid; Butterfly valve arranges opening adjusting device, when valve shaft rotates, driven rotary portion rotates, because iron ball withstands in the groove of described rotary part, thus iron ball can shift out in groove along with the rotation of rotary part, when valve shaft continues to rotate forward, iron ball enters in next groove, valve plate is made to turn to several angle, thus make butterfly valve form certain aperture, the interval angles that multiple groove can be set according to actual needs and arrange between groove, thus the different opening of butterfly valve can be set.The Pneumatic butterfly valve of dust pelletizing system of the present utility model, structure is simple, and response rapidly, has different opening, and easy to operate, not fragile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is that A-A in Fig. 2 is to sectional view.
Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the present embodiment provides a kind of Pneumatic butterfly valve of dust pelletizing system, the valve plate 3 comprising valve body 1, be positioned at the valve shaft 2 on valve body 1 and be installed on described valve shaft 2, a connecting rod 4 is fixed in one end of described valve shaft 2, described connecting rod 4 is connected to the cylinder arm of a cylinder 5, described connecting rod 4 can be driven to drive described valve shaft 2 to rotate by described cylinder 5; Described valve shaft 2 is also provided with opening adjusting device 6, and described opening adjusting device 6 comprises the annular seating 61 fixed with valve body 1, and being provided with in described annular seating 61 can the rotary part 62 of coaxial rotating, and described rotary part 62 is fixed on described valve shaft 2; On the sidewall of described annular seating 61, some arch shaped cavity 63 are provided with at described rotary part 62, described annular seating 61 is provided with the through hole 64 that radial direction is offered, be provided with Compress Spring 65 in described through hole 64, one end of the radial outside of described through hole 64 is bolted with block 66; One end of described Compress Spring 65 withstands on described block 66, and the other end withstands an iron ball 67, and described iron ball 67 withstands on described rotary part 62.
Described rotary part 62 is connected by key 8 with described valve shaft 2.
Described through hole is two.
Two described through holes are symmetricly set on described annular seating.
Described valve body 1 is provided with bearing 7, and described valve shaft 2 is installed on described bearing 7.
Adopt technique scheme, the Pneumatic butterfly valve of dust pelletizing system of the present utility model, is moved by the described connecting rod of flexible drive of cylinder arm, thus drives described valve shaft to rotate, and valve shaft rotates and valve plate is rotated, thus realizes the logical of butterfly valve and close, and responds rapid; Butterfly valve arranges opening adjusting device, when valve shaft rotates, driven rotary portion rotates, because iron ball withstands in the groove of described rotary part, thus iron ball can shift out in groove along with the rotation of rotary part, when valve shaft continues to rotate forward, iron ball enters in next groove, valve plate is made to turn to several angle, thus make butterfly valve form certain aperture, the interval angles that multiple groove can be set according to actual needs and arrange between groove, thus the different opening of butterfly valve can be set.The Pneumatic butterfly valve of dust pelletizing system of the present utility model, structure is simple, and response rapidly, has different opening, and easy to operate, not fragile.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
