Description
Technical field
The utility model relates to the SE field, specifically is a kind of actuator of board-like exhaust smoke valve.
Background technique
At present, high-rise all is equipped with ventilated smoke discharging pipeline, is provided with board-like exhaust smoke valve in the vertical pipeline section of ventilated smoke discharging pipeline.Board-like exhaust smoke valve comprises valve block, valve shaft, extension spring and actuator; Valve block is hinged in the vertical pipeline section through valve shaft; Valve shaft is positioned at 1/3rd places of the length direction of valve block, and the lower end of extension spring is fixed on valve block from the nearer end of valve shaft, and the upper end of extension spring is fixed on vertical pipeline section tube wall; Valve block is fixed with the extension arm away from an end of valve shaft; The upper end that hangs arm is fixed with peg, and actuator is installed in the vertical pipeline section, the peg of the extension arm of the actuator's ability hook or the valve block that gets loose.When actuator's hook was lived valve block away from the peg of an end of valve shaft, valve block was horizontal, and vertical with the vertical pipeline section, valve block is closed pipe section fully, and promptly board-like exhaust smoke valve is closed; Actuator gets loose valve block during away from the peg of the extension arm of an end of valve shaft, and valve block can rotate under the double action of gravity and extension spring, and when valve block rotated to vertical shape, the valve block aperture was maximum, and board-like exhaust smoke valve is opened.
The actuator of the board-like exhaust smoke valve of existing technology can only control through manual, but the urgent moment on fire, people need put out a fire or withdraw against time, and have no time to go to manual unlocking execution architecture by the actuator; So the actuator of the board-like exhaust smoke valve of existing technology is dangerous, inconvenient.
Summary of the invention
The technical problem that the utility model will solve is that a kind of actuator that can realize the board-like exhaust smoke valve that the board-like exhaust smoke valve of electronic control is opened is provided.
The technical solution of the utility model is, a kind of actuator of board-like exhaust smoke valve is provided, and it comprises base, electromagnet, fork, rocker, hook and axle sleeve; Be fixed with fork axle and main shaft on the base, the shell stator of electromagnet is fixed on the base, and fork is rotatable to be engaged on the fork axle; One end of fork and the mandrel of electromagnet are hinged, are provided with first stage clip between this end of fork and the shell stator of electromagnet, and the other end of fork is provided with breach; Rocker is rotatable to be linked on the main shaft; Be provided with torsion spring between rocker and the base, the fixture block of rocker is stuck under the effect of torsion spring in the breach of fork, and axle sleeve is also rotatable to be linked on the main shaft; And the lower end and the rocker of axle sleeve are fixed, and the upper end of axle sleeve is fixed with the hook of the valve block that is used for the board-like exhaust smoke valve of hook.
Adopt above structure board-like exhaust smoke valve actuator compared with prior art, have the following advantages:
The operating principle of opening board-like exhaust smoke valve of this actuator is: after the room catches fire, and to the electromagnet energising, the mandrel withdrawal of electromagnet; One end of drive fork overcomes the effect of first stage clip to be swung to electromagnet, and whole fork rotates around the fork axle, and an end of fork band first breach breaks away from rocker; The rocker that loses the breach restriction of fork rotates around main shaft under the effect of torsion spring; Simultaneously, axle sleeve, the hook fixed with rocker are also driven around main shaft by rocker and rotate, and then the hook of the peg hook of the extension arm of the valve block of feasible and board-like exhaust smoke valve and peg disengaging; At this moment; The valve block that loses the hook hook begins rotation under the double action of gravity and extension spring, valve block finally be vertically to the time, board-like exhaust smoke valve is opened.
In sum, the unlatching of the electronic realization valve body of the actuator of this board-like exhaust smoke valve ability, and no longer rely on operation manually to open valve body; Like this, when the room caught fire, people need not to be flushed to the actuator place; The manual unlocking valve; Get final product but open electromagnet power supply fast, the valuable time of saving is used for putting out a fire or withdrawing, so safer, more convenient, faster.
As improvement, it comprises that also one is fixed on the support on the base, and the pressing shaft that is used for the lifting fork is installed on the support; Like this, people's hand is pressed pressing shaft, the pressing shaft notched end of lifting fork that will make progress; Make the breach and the rocker of fork break away from, realize the process of the board-like exhaust smoke valve of manual unlocking, that is to say; This structure has realized the manual control that valve body is opened, the alternative scheme as electromagnet after malfunctioning, safer, more insurance.
As also improving, comprise two parallel mounting plates on the support, two mounting plates are provided with two mounting holes; Pressing shaft is linked in two mounting holes; The shaft part of pressing shaft between two risers is provided with radially latch, radially is provided with second stage clip between the mounting plate of latch and upside, like this; Unclamp the hand of pushing down pressing shaft, pressing shaft can automatically reset under the effect of second stage clip.
As improving, the top of hook also is provided with a limiting board again; Be fixed with a projection that is used to limit the rocker rotation on the base plate; Like this, when rocker break away from the fork breach be limited in rotate to an angle under the torsion spring effect after, will abut to projection; Can be spacing by projection, this is in order to prevent the excessive situation that is difficult to reset of rocker angle of swing; And after the room intensity of a fire put out, in the time of need closing board-like exhaust smoke valve, hand rest played the valve block of board-like exhaust smoke valve; Make valve block rotate around valve shaft, valve block rises away from the end swing of valve shaft, and the peg that is fixed on the extension arm of this end also is lifted; Peg can prop up the limiting board on hook top in uphill process, make to link up with the rotation that resets; Hook drives rocker through axle sleeve again and overcomes the torsion spring rotation that resets, and final rocker rotary reset snaps in the breach of fork again, looses one's grip at this moment; Valve block is performed mechanism's hook again, and is horizontal, and board-like exhaust smoke valve is closed fully; The peg that is hand push lifting valve block just can be locked valve body quickly and easily again, to sum up, the existence of this structure make valve body reset locking process convenient quick.
