Specific embodiment
Referring to FIG. 1 to FIG. 4, in order to preferably understand technical solution of the present invention, below by specifically
Embodiment is described in detail:
Referring to Fig. 1, check-valves includes flap 1, the flap rocker arm 2 connecting with flap 1, and it is connect with flap rocker arm 2
Shaft 3.When medium generates thrust to flap 1, valve opening is realized in 3 rotations to flap 1 around the shaft under the traction of flap rocker arm 2,
When medium thrust deficiency, flap 1 returns to valve position by self gravity.Flap rocker arm 2 is interconnected with shaft 3 by 31 phase of key
It connects.
Referring to Fig. 2, a kind of any tunable arrangement of check-valves flap maximum opening of the invention, 3 shaft of shaft of valve
Across valve body to extending outside valve body, the part outside valve body is connect with a damping arm 5, and can drive damping arm 5 into
Row is swung.The end of damping arm 5 is connected with weight bearing load 4.Referring to Fig. 3, weight bearing load 4 is detachable multiple-piece weight bearing piece,
If dry plate weight bearing piece is threadedly coupled with the connection structure of 5 end of damping arm, the specific weight for the piece that bears a heavy burden is according to medium in check-valves
Specific pressure demand determine, and can be adjusted at any time.After the thrust that the medium for flowing to flap 1 generates opens flap 1,
The gravity that can balance a part of flap 1 for load 4 of bearing a heavy burden, avoids when pressure medium is unstable, flap 1 is in gravity
Lower generation displacement fluctuation, carries out pressure medium and flow in influence runner, and the balanced action that flap 1 opens bigger weight bearing is more aobvious
It writes, ensures that the pressure and flow of the medium by check-valves in this way, avoid the huge fluctuation of medium pressure in system.
It is connected with position limit arm in shaft 3, and position limit arm can be driven to be swung, position limit arm is equipped with fan-shaped limit convex shoulder 6,
It is equipped with limit plate 7 with the ipsilateral valve outer wall of position limit arm, limit convex shoulder ride 6 is connected to the end of limit plate 7, so that limit
The rotational angle of arm is restricted, to limit the aperture of flap 1.
For example, limit convex shoulder 6 and limit can be passed through at this time if it is 45 degree that medium, which pushes the aperture of flap 1, under certain pressure intensity
The maximum opening of flap 1 is adjusted to 42 degree by position plate 7, and such medium thrust can more fully resist flap, swing it not.
Furthermore the gravity and medium thrust for load 4 of bearing a heavy burden can the unlatching of couple flap 1 promoted.When medium power reduces,
The gravity of weight bearing load 4 still can compensate the unlatching of flap 1, and flap 1 is kept to stablize in the upper position opened.The device
Purpose be that flap will not be swung when pressure medium fluctuation when making valve opening.
Referring to Fig. 4, limit plate 7 includes limit fixed plate 71 and limit adjustable plate 72, limit fixed plate 71 is positioned at valve
Boss structure on body sidewall；Limit fixed plate 71 occurs sliding or loosen under the drive of position limit arm in order to prevent simultaneously,
The one end for limiting fixed plate 71 is equipped with the limited block 9 that limitation limit fixed plate 71 is displaced, and is fixed using pin shaft.Limit adjustable plate
Regulating tank is offered on 72, and the adjusting bolt 8 by being arranged in regulating tank is slidably connected in limit fixed plate 71.
The limiting section 721 that adjustable plate end is equipped with arc is limited, which is that limit plate 7 is in contact and right with convex shoulder 6 is limited
The structure that limit convex shoulder 6 is limited, arcuate structure make the contact between the two relatively soft, avoid mechanical damage.Limit is adjusted
Graduation indication slot 722 is offered on section plate 72, it is interior to be equipped with attaching nut 723, it indicates below graduation indication slot 722 to show
The scale of 1 maximum opening position of flap, the finger being fixed on valve body is indicated for scale, to show the current maximum of flap
Aperture.Regulating tank two sides are equipped with guide groove 724, are equipped with fixture nut 725 in guide groove 724, with graduation indication slot 722 and even
723 collective effect of connected nut guarantees limit adjustable plate 72 horizontal movement direction and it is fixed
Using a kind of any tunable arrangement of check-valves flap maximum opening of the invention, when medium pushes flap 1, flap
1 drives flap rocker arm 2 and shaft 3 to rotate, and shaft 3 drives damping arm 5 and weight bearing load 4 to rotate, this outer shaft 3 drives position limit arm
6 rotations, position limit arm 6 rotate the limitation that angle is limited 7 position of position plate.Load 4 of bearing a heavy burden uses screw thread using multiple-piece weight bearing piece
Be mounted in damping arm 4, to balance the gravitational effects of flap 1 so that in the case where medium pressure change flap 1 not therewith into
Row positional fluctuation, the quantity and load position for changing weight bearing piece can adjust pair according to the weight of the pressure of medium and flap 1
The equilibrant force of flap 1.
When needing to adjust limit plate 7, the fastening bolt on limit plate 7 is first unclamped, is adjusted adjusting bolt 8 by rotation
The position of adjustable plate 72 is limited, fastening bolt is screwed again after determining limit 72 position of adjustable plate, to fix limit plate 7, and leads to
It crosses limit plate 7 and limits the rotation of position limit arm 6, and then control the maximum opening of flap 1.
After valve opening meets requirement and system run all right, valve can be directly read according to the scale of limit plate 7
The flap aperture of door.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
