Abstract
The utility model discloses a pneumatic roller type sealing gate valve, its constitution includes: the storehouse body, the internal portion in storehouse is formed with the well cavity that holds the material, a sealing unit, sealing unit is arranged in the cavity top, sealing unit includes gyro wheel row, picture peg and guide rail, the picture peg is closely laminated on the gyro wheel is arranged, the picture peg can make a round trip to slide along the extending direction that the gyro wheel was arranged on the guide rail, a drive unit, drive unit is connected with the picture peg, and the drive picture peg can slide along the guide rail back and forth. Compared with the prior art, the beneficial effects of the utility model are that: (1 ) sealing unit adopts gyro wheel in rows formula, becomes rolling friction with traditional sliding friction like this, has improved the flexibility that the picture peg removed greatly, has reduced the noise, (2 )The storehouse physical stamina of cavity is carried out the secondary to the material of taking out board pull in -process and taking out of and is retrieved in being equipped with, has improved the leakage efficiency greatly.
Description
Technical field
This utility model relates to transport field of storing in a warehouse, and is specifically related to a kind of pneumatic roller formula seal gate valve.
Background technology
Sealing is an important step during modern industry produces, development along with the productivity, the most all kinds of accurate gate valves are multifarious, emerge in an endless stream, especially liquid and gas this part, the most structure of this kind of gate valve is complicated, higher to processing request, and cost of manufacture is higher, maintaining is difficult to, it is easily damaged under adverse circumstances, for dust-like material inapplicable；Although traditional plate seals simple in construction, but there is inevitable strip phenomenon during plate moves, for fine particle material sealing effectiveness inconspicuous, and there is bigger friction in plate in draw process.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of structural principle is simple, the easy to make and pneumatic roller formula gate valve of favorable sealing property.
For solving above-mentioned technical problem, the technical solution of the utility model is:
A kind of pneumatic roller formula seal gate valve, its composition includes:
One warehouse, described warehouse is internally formed the cavity accommodating material；
One sealing unit, described sealing unit is positioned at above cavity, and described sealing unit includes roller row, plate and guide rail, and described plate fits tightly on roller is arranged, and described plate can slidably reciprocate along the bearing of trend of roller row on guide rail；
One driver element, described driver element is connected with plate, drives plate can slidably reciprocate along guide rail.
Preferably, described driver element is cylinder, the piston rod of described cylinder and the fixing connection of plate.
Preferably, the top of described cavity is divided into two row annular seal spaces, and described roller ranks in the first annular seal space, and described driver element is positioned at the second annular seal space, and described plate and guide rail are fed through the first annular seal space and the second annular seal space.
Preferably, described roller row includes three groups of rollers.
Preferably, described plate is connected with piston rod bolt.
Preferably, described second annular seal space is arranged over packaged type cover plate.
Compared with prior art, the beneficial effects of the utility model are: (1) sealing unit uses roller row's form, so traditional sliding friction is become rolling friction, substantially increases the motility that plate moves, reduce noise；(2) warehouse being provided with cavity can carry out secondary recovery to the material taken out of in pumping board draw process, substantially increases leakage efficiency；(3) plate is connected with piston rod bolt, is convenient for changing, and adapts to the demand of different process；(4) driver element is air cylinder driven, reliable and stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, warehouse；2, cavity；3, roller row；4, plate；5, guide rail；6, cylinder；7, the first annular seal space；8, the second annular seal space；9, cover plate.
Detailed description of the invention
By making, architectural feature of the present utility model and effect of being reached are had a better understanding and awareness, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
A kind of pneumatic roller formula seal gate valve, its composition includes:
One warehouse 1, described warehouse 1 is internally formed the cavity 2 accommodating material, and the warehouse 1 being provided with cavity 2 can carry out secondary recovery to the material taken out of in pumping board draw process, substantially increase leakage efficiency.
One sealing unit, described sealing unit is positioned at above cavity 2, described sealing unit includes roller row 3, plate 4 and guide rail 5, described plate 4 fits tightly on roller row 3, and described plate 4 can slidably reciprocate along the bearing of trend of roller row 3 on guide rail 5, and described roller row 3 includes three groups of rollers, sealing unit uses roller to arrange 3 forms, so traditional sliding friction is become rolling friction, substantially increase the motility that plate 4 moves, reduce noise.
One driver element, described driver element is connected with plate 4, and described driver element is cylinder 6, and the piston rod of described cylinder 6 and plate 4 bolt connect, and drives plate 4 can slidably reciprocate along guide rail 5.
The top of described cavity is divided into two row annular seal spaces, and described roller ranks in the first annular seal space 7, and described driver element is positioned at the second annular seal space 8, and described plate 4 and guide rail 5 are fed through the first annular seal space 7 and the second annular seal space 8.
Described second annular seal space 8 is arranged over packaged type cover plate 9, and convenient second annular seal space 8 that enters carries out technique initialization.
Operation principle of the present utility model is:
When cylinder 6 is in elongation state, plate 4 is positioned at left end and contacts with bulkhead, and gate valve is closed；When cylinder 6 is in contraction state, moving right, gate valve is opened；There is some powder material can take out of along with plate 4 during opening, fall into the right one side of something of warehouse 1 and together import lower end splicing equipment with unclassified stores.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; simply principle of the present utility model described in above-described embodiment and description; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the range of claimed this utility model.The protection domain that this utility model requires is defined by appending claims and equivalent thereof.
