Description
Technical field
This utility model relates to defense equipment field, particularly to a kind of manual sealed valve of double link.
Background technology
Sealed valve is the visual plant controlling airflow direction in basement air pipeline, is needing appropriate regulation air quantity
On pipeline, use the manual sealed valve of double link, in addition to the function opened and closed, moreover it is possible to regulate air quantity in right amount, be in civil air defense constructions and installations
Visual plant.
The Chinese patent " dual-purpose link-type sealed valve " of Publication No. CN204573266U discloses a kind of dual-purpose connecting rod
Formula sealed valve, including motor and speed reducer case, spindle nose connects worm gear, is provided with worm screw and ratch, snail in decelerating chassis
Bar engages with worm gear and ratch respectively, and worm end connects the handle that can separate with worm screw or connect；Motor drives ratch to turn
Dynamic.
When but this dual-purpose link-type sealed valve has the disadvantage in that main axis, drive first connecting rod to rotate, first
Connecting rod drives second connecting rod motion, and second connecting rod band movable valve rises and upset, and the upset of valve opening and closing fully relies on second even
The effect of bar, the longest when valve in case of emergency opens and closes, the rotation of the most long-term untapped valve second connecting rod
Rotating by bigger resistance when the laying dust that gets rusty, valve upset opens and closes and time-consumingly can become longer, causes promptly using
Time there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of manual sealed valve of double link, has the effect that quickly upset opens and closes.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of double link is the closeest
Valve closing door, including valve body, valve plate, be fed through described body wall after be rotationally connected with the main shaft of described valve interior wall, fixing set
It is placed in the fixed arm in described valve body, described main shaft is installed with a pair cursor, be provided with in the middle part of described valve plate and be positioned at described turning
Flip-arm between swing arm, described cursor is connected on described flip-arm away from one end bearing pin of described main shaft, described main shaft
Being fed through described fixed arm post gap and be matched with described fixed arm, described fixed arm is provided with support seat, and described support seat sets
Having one end bearing pin on described support seat and the other end is articulated with the connecting rod of described flip-arm upper end, described connecting rod is near institute
The one end stating support seat is provided with the drag ring abutting described main shaft, and during described main axis, described drag ring is in linkage with described main shaft
And the upset of described flip-arm upper end enters in the gap between described cursor.
By using technique scheme, use handle rotating spindle, drive cursor to rotate, cursor drive flip-arm to
Upper motion, after being fed through fixed arm due to cursor and matched in clearance, makes fixed arm be fixed on valve interior wall all the time, turns with main shaft
The flip-arm upper end moved and rotate and the distance supported between seat have the trend of reduction, owing to connecting rod two ends connect respectively
Supporting on seat and flip-arm, overturning after connecting rod stress, flip-arm upper end can the company made from the distance change of flip-arm upper end
Upset is occurred to cause flip-arm to overturn in uphill process, secondly, by arranging in connecting rod after extension bar stress
With the drag ring of main shaft linkage, during main axis, under the effect of frictional force, drag ring rotates, and drag ring turns with main shaft
Dynamic in opposite direction, drive connecting rod to rotate, the connecting rod of rotation drive flip-arm upper end towards the intermittent motion between cursor,
Owing to one end bearing pin of cursor is connected on flip-arm, flip-arm can be with cursor and flip-arm bearing pin connecting portion as fulcrum
Overturning, flip-arm drives valve plate upset, reaches main shaft and drives the motion of drag ring, connecting rod, flip-arm, valve plate successively,
Realize the upset of valve plate, by using two groups of different upset system collaboration belts to move the upset of valve plate, make double link the most airtight
The keying of valve is more flexible, shortens the time of valve opening and closing, makes valve opening and closing more quick.Eliminate the manual airtight valve of double link
Door opens slower potential safety hazard when urgent use, improves security performance.
Of the present utility model it is further arranged to: described cursor is welded on described main shaft.
By using technique scheme, cursor can be securely attached on main shaft, can drive rotation during main axis
Arm rotates, it is to avoid cursor repeatedly opens and closes and the phenomenon ruptured that comes off occurs.
Of the present utility model it is further arranged to: described flip-arm includes two bend arms bent towards described main shaft,
Described rotation wall is provided with the first bearing pin being fed through described cursor, described bend arm successively.
By using technique scheme, two bend arms make valve plate be more uniformly stressed when overturning, and flip-arm turns over
When turning, with the first bearing pin as fulcrum, main axis drives drag ring, connecting rod to rotate, and connecting rod drives flip-arm upper end stress,
Making flip-arm can be that fulcrum overturns around the first bearing pin.
Of the present utility model it is further arranged to: described connecting rod is provided with and is fed through described bend arm, described company successively
Second bearing pin of extension bar.
By using technique scheme, make mutually rotate between connecting rod and bend arm by the second bearing pin, upset
Time mutually rotation can occur, make the manual sealed valve of double link normally to work.
Of the present utility model it is further arranged to: described connecting rod is provided with the friction being distributed in described support seat both sides
Ring, described drag ring is integrally formed in described connecting rod, described connecting rod be provided be fed through successively drag ring described in side,
Described support seat, the 3rd bearing pin of opposite side drag ring.
By using technique scheme, by arranging drag ring at support seat two ends, make energy between main shaft and drag ring
It is fully contacted, it is ensured that main axis can drive drag ring to rotate.3rd bearing pin ensures that connecting rod can be with the 3rd bearing pin as axis
Rotate.
Of the present utility model it is further arranged to: described drag ring is integrally formed in described connecting rod.
By using technique scheme, drag ring rotational drives connecting rod to rotate, and rubs during life-time service
Ring will not loosen or come off between connecting rod, extends the service life of the manual sealed valve of double link.
Of the present utility model it is further arranged to: described flip-arm lower end is welded with mounting disc, and described mounting disc is provided with
It is fed through described mounting disc rear thread and is connected to the bolt of described valve plate.
By using technique scheme, flip-arm lower end is bigger, between flip-arm and valve plate with the contact surface of valve plate
Annexation more firmly and is stablized, and will not fall off when urgent use.
In sum, this utility model has the advantages that and uses the main shaft rotated to drive drag ring, connection successively
Rotating of bar drives flip-arm and the upset of valve plate, and cursor drives when turning on flip-arm at fixed arm and the band of connecting rod simultaneously
Also flip-arm and valve plate can be overturn under Dong, play the collaborative effect that valve plate is overturn, make double link the most airtight
The keying of valve is more quick, shortens the time of valve opening and closing, eliminates the manual sealed valve of double link and opens and closes when urgent use
Slower potential safety hazard, improves security performance.
