The trend of valve body, the other end of weight crank be provided with close to switch match close to switch detection plate, it is complete in valve block
Inspection can be matched with close to switch detection plate by being provided with when contract fully valve body close on valve outer wall corresponding to switch detection plate
Side valve piece whether close in place close to switch, also set up outside valve body and several help pass gas to assist valve block valve body
Cylinder helps the cylinder body for closing cylinder mutually to fix with valve outer wall, and the piston rod for closing cylinder is helped to be hinged with weight crank.
Further, a kind of blower non-return valve above-mentioned, in which: there are two to assist valve block to close for setting outside valve body
Valve closing body helps pass cylinder, and two are helped weight crank of the piston rod for closing cylinder respectively with shaft two sides to be hinged.
Further, a kind of blower non-return valve above-mentioned, in which: component is adjusted by position close to switch and is installed on valve body
On, it includes: and the water being installed on valve outer wall to install close to switch close to switch installation board that position, which adjusts component,
Flat fixed plate is provided with the elongate holes being axially arranged along valve body on horizontal fixed plate, at the top close to switch installation board
It is vertically provided with long bolt, long bolt stretches out the elongate holes of horizontal fixed plate upwards and exists by a pair to tight nut check
On horizontal fixed plate.
Through the implementation of the above technical solution, the beneficial effects of the present invention are: the valve block of blower non-return valve closes position in place
Accurately, so that blower non-return valve to close signal in place accurate and reliable, it is ensured that blower air dispensation system can securely and reliably put into operation, and reduce high
The risk of the disconnected wind Slagging of furnace, improves the safety in utilization of system.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of blower non-return valve of the present invention.
Fig. 2 is shown in Fig. 1 left view direction close to the positional diagram of switch detection plate and close switch.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
As shown in Figure 1 and Figure 2, a kind of blower non-return valve, including valve body 1, are provided with valve block 2, valve in valve body 1
Piece 2 is articulated in valve body 1 by shaft 3, the inner wall of valve body 1 is provided with a circle Sealing shield ring 4, valve is stretched out in one end of shaft 3
Simultaneously fixing sleeve is equipped with weight crank 5 to body 1, one end of weight crank 5 is provided with weight 6, weight 6 is by weight crank 5 and turns
Axis 3 makes valve block 2 be swung down to the sealing that is in contact with Sealing shield ring 4, with around the shaft 3 always to completely close valve body 1
Trend, the other end of weight crank 5 be provided with close to switch 7 match close to switch detection plate 8, valve block 2 completely
Being provided with when valve body 1 close on 1 outer wall of valve body corresponding to switch detection plate 8 can match with close to switch detection plate 8
Detection valve block 2 whether close in place close to switch 7；It is provided with outside valve body 1 to assist the first of valve block valve body to help
Close cylinder 9 with second help close cylinder 10, first help close cylinder 9 piston rod with second help pass cylinder 10 piston rod respectively with turn
The weight crank 5 of axis two sides is hinged, and by helping pass cylinder to may insure that valve block completely closes valve body, the use for improving equipment is steady
Qualitative and safety；In the present embodiment, it adjusts component by position close to switch 7 to be installed on valve body 1, position adjusts component
It include: and the horizontal fixed plate 12 that is installed on 1 outer wall of valve body installing close to switch 7 close to switch installation board 11,
The elongate holes 13 being axially arranged along valve body are provided on horizontal fixed plate 12, vertical close to the top of switch installation board 11
It is provided with long bolt 14, long bolt 14 stretches out the elongate holes 13 of horizontal fixed plate 12 and by a pair to tight nut 15 upwards
It is locked on horizontal fixed plate 12, the front-rear position close to switch is adjusted in synchronism by moving long bolt along elongate holes,
It is adjusted in synchronism by moving up and down long bolt in long strips hole close to the upper and lower position of switch, such installation and adjustment are close
Switch is more convenient；
Working principle of the present invention is as follows:
In blast furnace blower air-supply, valve block 2 can overcome the gravity of weight 6 under the action of the wind and rotate along air supply direction
Axis 3 rotates down and opens valve body, and when blast furnace failure breaks wind, valve block 2 can be against air supply direction under the gravity of weight
3 turn to the sealing that is in contact with Sealing shield ring 4, around the shaft to completely close valve body 1, while first helps the piston for closing cylinder 9
Bar can move downward on drop-down weight crank 5 close to one end of weight, and second helps the piston rod for closing cylinder 10 that can move upwards
One end on weight crank 5 far from weight is lifted, so that valve block 2 be made to completely close valve body；Pass gas is helped in weight 6 and respectively in valve block 2
During progressively closing off valve body under the action of cylinder, it is installed on can gradually abut up on weight crank 5 close to switch detection plate 8
Proximity closely switch 7 just moves to corresponding with close to switch 7 when valve block 2 completely closes valve body 1 close to switch detection plate 8
Position, at this time close to switch 7 can send accurately valve block pass signal fan air dispensation system, blower air dispensation system receive in place
Automatic safe puts into operation after valve block closes signal in place.
The invention has the advantages that position is accurate in place for the valve block pass of blower non-return valve, so that blower non-return valve pass is believed in place
It is number accurate and reliable, it is ensured that blower air dispensation system can securely and reliably put into operation, and reduce blast furnace and break the risk of wind Slagging, improve system
Safety in utilization.
