Description
Technical field
The utility model relates to the SE field, specifically is a kind of actuator of exhaust smoke valve.
Background technique
At present, high-rise all is equipped with ventilation duct, is provided with exhaust smoke valve in the ventilation duct.Exhaust smoke valve comprises valve body, is provided with valve block in the passage of valve body, is fixed with main shaft on the valve block, and main shaft stretches out outside the valve body and with actuator and is connected.Actuator is through rotating spindle, thereby drives the valve block rotation, and then realizes the switching of whole valve body, and during like the channel vertical in valve block and the valve body, valve block blocks passage, and valve body is closed, during the interior channel parallel of valve block and valve body, and the aperture maximum of whole valve body.The actuator of the 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 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 exhaust smoke valve that electronic control exhaust smoke valve is opened is provided.
The technical solution of the utility model is, a kind of actuator of exhaust smoke valve is provided, it comprise valve body and with valve body in the fixing main shaft of valve block; Main shaft is rotatable to be engaged on the valve body, and it also comprises a rocking arm, a rocker, a fork and an electromagnet, is fixed with base on the valve body; Be fixed with fork axle and rocker axle on the base, the shell stator of electromagnet also is fixed on the base, and an end of the outer end of the mandrel of electromagnet and fork is hinged; Be provided with first stage clip between this end of fork and the shell stator, fork is rotatable to be engaged on the fork axle, and the other end of fork is provided with breach; Rocker is rotatable to be engaged on the rocker axle, is provided with torsion spring between rocker and the base, and an end of rocker is in the breach that pushes against under the effect of torsion spring at fork; The other end of rocker is provided with hook, and rocking arm is fixed on the main shaft, is fixed with extension spring between an end of rocking arm and the valve body; the other end of rocking arm is provided with tommy bar, and the tommy bar of rocking arm is hooked in the hook of rocker under the effect of extension spring.
Adopt above structure exhaust smoke valve actuator compared with prior art, have the following advantages:
The operating principle of opening 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 and swings to electromagnet; Whole fork rotates around the fork axle, and the notched end of fork breaks away from rocker, and the rocker that loses the breach restriction of fork rotates around the rocker axle under the effect of torsion spring; And then make the hook of the rocker the other end and the tommy bar of rocking arm break away from; At this moment, the spacing rocking arm of hook hook that loses rocker rotates under the extension spring effect, i.e. the pull strap of extension spring shakes the arm rotation; And rotate with valve block that the fixing main shaft of rocking arm also drives the valve body of exhaust smoke valve, realize opening of whole valve body.
In sum, the unlatching of the electronic realization valve body of the actuator of this 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 valve body, is sheathed with a pressing shaft on the support; The head of pressing shaft is a tip, and tip is between the breach of rocker and fork, like this; People manually press down pressing shaft, and the tip of pressing shaft can back down fork and rocker, make rocker break away from the fork breach; Thereby inspire the rotation of rocker, rocking arm, main shaft, finally, that is to say through the opening of manual realization exhaust smoke valve; 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 risers on the support, two risers 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 riser of latch and inboard, like this; Unclamp and press down the hand of pressing bar, pressing bar can automatically reset under the effect of second stage clip.
As improving again, a runner is installed on the support, coiling has cable wire on the runner, and an end of the free end of cable wire and rocking arm band tommy bar is fixed; One end of rocker buckle also is provided with a baffle plate, and baffle plate is positioned at the hook inboard, like this, and when the intensity of a fire in room is just put out very soon; In the time of need closing exhaust smoke valve, rotating wheel tightens up cable wire, and cable wire overcomes extension spring effect traction rocking arm rotary reset; the tommy bar of rocking arm can be against the baffle plate of living rocker in the process that rocking arm resets, and then promotes also rotary reset of rocker, and the rocker rotation that resets snaps in the breach of fork up to rocker one end again, simultaneously the hook of the other end of rocker also just in time hook live the tommy bar of rocking arm; at this moment, valve body is also closed again, and whole actuator all resets; to sum up, and through this structure, whole actuator very easily can reset.
As further improvement, respectively be provided with a pilot hole on two risers of support, rotatablely in two pilot holes be combined with a rotating shaft, runner is fixed on the shaft part between two risers of rotating shaft, and such is simple in structure, easy to assembly.
As improving again again; The stage casing of fork is provided with the projection that is used to limit the rocker rotation; Like this, an end of rocker breaks away from the restriction of fork breach and will under the effect of torsion spring, rotate to the direction near electromagnet, rotate to the projection place in fork stage casing when rocker; Can be spacing by projection, this is in order to prevent the excessive situation that is difficult to reset of rocker angle of swing.
As also further improving, also be fixed with little switch that touches on the base, little contact that touches switch is positioned at the side of rocker near electromagnet; Like this, rocker can touch little switch that touches after breaking away from breach restriction beginning rotation of fork; Little switch that touches can send signal, and the expression valve body has begun to open.
