Description
Technical field
The utility model relates to a kind of valve, in particular to a kind of high-pressure large-caliber valve of air pressure driving worm and gear.
Background technique
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 extremely difficult by manual operation.Operation circle number 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 where 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 worm and gear.
Utility model content
The main purpose of the utility model is to provide a kind of high-pressure large-caliber valves of air pressure driving worm and gear, can be with
Effectively solve the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of high-pressure large-caliber valve of air pressure driving worm and gear, including valve, worm gear, worm screw, shaft coupling and pneumatic
Motor, attachment base is arranged in the valve top part, and has ball-screw in attachment base, and worm gear is arranged in the ball-screw side,
And worm screw is arranged by rotation slot in worm gear side, the attachment base bottom connects valve deck by protective jacket, and by close in valve deck
Valve rod is arranged in sealing groove slot, and valve body, and valve deck bottom connecting valve seat, the valve base inner wall tool is bolted in the valve deck bottom
There is valve plate, and stem bottom is disposed through between valve plate, described worm screw one end passes through the driving end of shaft coupling and air motor
Connection.
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 worm screw other end passes through rotation axis connection handwheel.
Further, the ratcheting connection of the worm and wheel.
Compared with prior art, the utility model has the following beneficial effects: device is connected on valve by attachment base,
Worm gear and ball screw are made of one formula.Worm gear mechanism is commonly used to movement and power between two alternating axis of transmitting.Snail
It is equivalent to wheel and rack in wheel and worm screw therebetween plane, worm screw is again similar to screw configuration.Available very big biography
Dynamic ratio, it is compacter than crossed helical gears mechanism, valve operation power can be substantially reduced.It contacts, holds for line between two-wheeled mesh tooth face
Loading capability is much higher than crossed helical gears mechanism.Worm-drive is equivalent to worm drive, is driven for multi-tooth meshing, therefore is driven flat
Surely, noise very little.With self-locking performance.When the lead angle of worm screw is less than the equivalent friction angle of engagement wheel between cog, mechanism has certainly
Lock property, it can be achieved that reverse self-locking, i.e., can only worm screw drive worm gear, and worm screw cannot be driven by worm gear, reverse self-locking can rise
Safeguard protection effect, when from air motor inlet charge, the pressure energy of compressed air is converted to rotary force by motor, is passed through
Shaft coupling drive worm screw, worm screw by between two alternating axis movement and power be transmitted on worm gear, then by ball-screw rotation
Drive stem movement by the opening and closing of the controllable valve of commutation of air motor, it only need to be by tracheae and motor air inlet
Being connected can be remotely operated, and existing security risk when avoiding scene with press operation, the high revolving speed of air motor can be significantly
Improve the opening and closing efficiency of valve.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of high-pressure large-caliber valve of air pressure driving worm and gear, including valve 13, worm gear 1, snail
Attachment base 6 is arranged at the top of the valve 13, and has ball-screw 5, institute in attachment base 6 for bar 2, shaft coupling 3 and air motor 4
5 side of ball-screw setting worm gear 1 is stated, and worm screw 2 is arranged by rotation slot in 1 side of worm gear, 6 bottom of attachment base passes through anti-
Sheath connects valve deck 8, and valve rod 7 is arranged by seal groove slot in valve deck 8, and valve body 9 is bolted in 8 bottom of valve deck,
