Description
Technical field
The present invention relates to a kind of valve, more particularly to a kind of high-pressure large-caliber valve of air pressure driving turbine and worm.
Background technology
Existing valve operation torque is big, since pressure height causes the frictional force between valve plate valve seat very big, controlled valve institute
The operating force needed is too big, only relies on manual operation extremely difficult.The operation number of turns needed for controlled valve is more, due to valve aperture
Very big, stroke of the valve from opening closing is also very big, such as 105 operating pressure 105MPa/180 (valve latus rectum 180mm)
Valve needs 30 ~ 40 circles from pass is reached, and the operating time is very long, due to all operations in the case of high pressure of such valve, scene
There is very big hidden danger when band press operation, for this purpose, it is proposed that a kind of high-pressure large-caliber valve of air pressure driving turbine and worm.
Invention content
The main purpose of the present invention is to provide the high-pressure large-caliber valves that a kind of air pressure drives turbine and worm, can be effective
Solve the problems in background technology.
To achieve the above object, the technical solution that the present invention takes is：
A kind of high-pressure large-caliber valve of air pressure driving turbine and worm, including valve, turbine, scroll bar, shaft coupling and air motor,
Connecting seat is arranged in the valve top part, and has ball-screw in connecting seat, and turbine, and turbine is arranged in the ball-screw side
Scroll bar is arranged by rotation slot in side, and the connecting seat bottom connects valve deck by protective jacket, and passes through seal groove slot in valve deck
Valve rod is set, and valve body, and valve deck bottom connecting valve seat is bolted in the valve deck bottom, and the valve base inner wall has valve
Plate, and stem bottom is disposed through between valve plate, described scroll bar one end is connected by the driving end of shaft coupling and air motor.
Further, the rotation axis connection of the turning end and stem bottom of the ball-screw bottom.
Further, described air motor one end has air inlet.
Further, the scroll bar other end is by rotating axis connection handwheel.
Further, the scroll bar and the ratcheting connection of turbine.
Compared with prior art, the present invention has the advantages that：Device is connected to by connecting seat on valve, turbine
It is made of one formula with ball screw.Turbine worm mechanism is commonly used to transmit the movement between two alternating axis and power.Turbine with
Scroll bar is equivalent to wheel and rack in plane therebetween, and scroll bar is again similar to screw configuration.Prodigious transmission ratio can be obtained,
It is compacter than crossed helical gears mechanism, valve operation power can be substantially reduced.It is contacted for line between two-wheeled mesh tooth face, bearing capacity
It is much higher than crossed helical gears mechanism.Worm-drive is equivalent to worm drive, is driven, therefore stable drive, makes an uproar for multi-tooth meshing
Sound very little.With self-locking performance.When the lead angle of scroll bar is less than the equivalent friction angle of engagement wheel between cog, mechanism has self-locking performance,
Reverse self-locking can be achieved, i.e., can only scroll bar drive turbine, and scroll bar cannot be driven by turbine, reverse self-locking can play safe guarantor
Shield acts on, and when from air motor inlet charge, the pressure energy of compressed air is converted to rotary force by motor, passes through shaft coupling
Drive scroll bar, scroll bar by between two alternating axis movement and power be transmitted on turbine, then pass through ball-screw rotation drive valve
Bar moves the opening and closing that can control valve by the commutation of air motor, and only tracheae need to be connected just with motor air inlet
Remote operation can be carried out, existing security risk, the high rotating speed of air motor are greatly improved valve when avoiding scene with press operation
The opening and closing efficiency of door.
