Description
Technical field
The present invention relates to slide valve field more particularly to a kind of reciprocating slide valves.
Background technology
Currently, large-scale slide valve is all to drive valve plate movement using screw rod, the opening and closing of valve are realized, due to valve
Plate is big, and the displacement distance of screw rod is longer, therefore the space occupied is larger, can not be in small space application, and large-scale slide valve
In seal aspect, there is also deficiencies, if the sealing tension between valve plate and valve body, are easy to damage sealing element, seal Song Zerong
Easily cause leakage.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of reciprocating slide valves, solve the contradiction in sealing and gap,
Occupied space is reduced simultaneously, small space is suitble to use.
The present invention is achieved through the following technical solutions, provides a kind of reciprocating slide valve, including be equipped with medium channel
Valve body, the valve plate that the medium channel can be cut off, and the driving device that drives the valve plate to be slided in valve body is described
It is provided with elastic pressurized sealing element between valve body and valve plate, the rack for sliding along direction setting, institute are installed on the valve plate
It includes being threaded through on the valve body and the couple axle of one end connection worm-gear speed reducer to state driving device, is pacified on the couple axle
Equipped with driving gear, the intermediate gear that is also equipped on the valve body while being engaged with the driving gear and rack.Driving dress
Setting can also be automatically controlled by hydraulic cylinder or pneumatic cylinder.
Power is reached valve plate by this programme by rack pinion, realizes the fast and reliablely mobile of valve plate, structure letter
It is single, by the way that intermediate gear is arranged, the size of driving gear is reduced, small space is suitble to use, installation is also more convenient, and is utilized simultaneously
The self-locking function of turbine worm reducer, the accuracy of combination gear rack-driving can make valve plate be parked in any opening degree；To elasticity
When pressurization part internal pressurization, sealing element expansion, realize it is in sealing contact with valve plate and valve body, to realize slide valve
Reliable sealing.
As an optimization, the rack is located at the side of the valve plate, and the elastic pressurized sealing element includes being located at valve plate end
Between face and valve body and be fixed on the both ends on valve body sealing elastic tube and one end be connected to the elastic tube, the other end
It is connected to the forcing pipe of pressure source.Rack is arranged on valve plate side this prioritization scheme, when slide valve size is smaller, is arranged one
The balance sliding of valve plate can be realized in rack, is suitble to the use of small size slide valve, pours Jie into elastic tube by forcing pipe
Matter is pressurizeed, and elastic tube swelling is made, and realizes the sealing of valve plate end face and valve body.
As an optimization, the strip hole along valve plate glide direction is offered on the valve body, and opening is equipped in the strip hole
Outwardly, towards the U-shaped elastic component of valve plate end face, the two sides of the U-shaped elastic component are fixed on by pressing plate on valve body closing face,
The elastic tube is located in the cavity that the U-shaped elastic component is surrounded with pressing plate, and the forcing pipe is pierced by the pressing plate.This optimization side
In case, elastic tube internal pressure expands after increasing, and U-shaped elastic component is made also to expand, the closing face of U-shaped elastic component with
Valve plate end face seal contacts, and realizes sealing, is protected elastic tube formation by the way that U-shaped elastic component is arranged, avoids the movement pair of valve plate
Elastic tube causes to wear, while U-shaped elastic component being fixed by pressing plate, not only fixed reliable, but also realizes U-shaped elasticity
The two sides of part and the sealing of valve body.
As an optimization, the guide groove for valve plate sliding is installed in the valve body, in the guide groove described in setting
Elastic tube, the two sides of the valve plate are separately installed with the idler wheel rolled along the guide groove inner wall.By the way that idler wheel is arranged not

Small valve plate deformation, prolongs the service life；There is provided guiding by the way that guide groove is arranged for the sliding of valve plate, at the same using guide groove as
Sealing space, when medium channel is connected, elastic tube is in contraction state, has gap between valve plate and valve body so that valve plate
Movement will not wear elastic tube, and when valve plate is closed, medium is poured into elastic tube, its internal pressure is made to increase, and elastic tube is swollen
It is contacted with valve plate and valve seal after swollen, realizes sealing.
As an optimization, several mudholes arranged along valve plate glide direction are offered on the guide groove.It is arranged by being arranged
Dirty hole, the impurity between valve plate and guide groove can be extruded mudhole when valve plate moves, keep the movement of valve plate more smooth.
As an optimization, the rack is located on the end face of the valve plate, and closure is installed on the sealing surface of the valve plate
Cyclic spring pipe, the cyclic spring pipe are equipped with the forcing pipe of connection pressure source.Rack is arranged in valve plate this prioritization scheme
End face on, balance when valve plate being made to move is more preferable, and the cross force when gear drive at both ends is cancelled out each other, and valve plate is avoided
Glance off, valve plate movement in place after, pressurizeed into cyclic spring pipe by forcing pipe, after cyclic spring tube swelling with valve body,
Valve plate is in sealing contact, realizes sealing.
As an optimization, the jackscrew that can be pushed up to the valve plate side is also equipped on the valve body, the jackscrew is logical with valve body
Cross threaded connection.Valve plate can be pushed to be moved to valve body by rotating jackscrew, keep the sealing surface of valve plate and valve body even closer
Fitting, further improves the reliability of sealing.
As an optimization, the valve body includes two valve seats being oppositely arranged, and the detachable affixed and difference with the valve seat
Valve body plate positioned at valve plate both sides, the medium channel and jackscrew are respectively positioned on the valve body plate.The valve body profit of this prioritization scheme
Surround valve chamber with valve seat and valve body plate, it is simple in structure, and it is convenient to overhaul when dismantled.
As an optimization, the flange short tube being detachably connected with valve body plate is equipped in the medium channel, the flange is short
The outer circle of pipe and valve body plate are in sealing contact, and the inner face of flange short tube and the valve plate are in sealing contact.This prioritization scheme utilization method
The end face of blue short tube is in sealing contact with valve plate, further ensures sealing effect, and the area by reducing sealing surface, avoids
Problem poorly sealed caused by sealing facial disfigurement, keeps sealing relatively reliable.
As an optimization, the wedge placed vertically is fixedly provided on the valve plate, and the small end of the wedge is downward.Wedge
Being arranged not only can be by jackscrew by the tighter of valve plate and valve body pressure, but also increases the component for preventing valve plate from sliding, to valve plate
Fixation it is relatively reliable, valve plate movement exits jackscrew when there is bite, to reduce the frictional force of valve plate movement.
Beneficial effects of the present invention are：Power is reached into valve plate by rack pinion, realizes the fast and reliable of valve plate
Ground moves, simple in structure, by the way that intermediate gear is arranged, reduces the size of driving gear, small space is suitble to use, install also more
It is convenient, while using the self-locking function of turbine worm reducer, the accuracy of combination gear rack-driving can be such that valve plate is parked in and appoint
Meaning aperture, can be fixed valve plate position using jackscrew, and contact of the valve plate with valve body can be made closer, is further ensured that
Sealing effect.
