Abstract
The utility model provides an automatic open-close device for an air door of a burner, which comprises a pressure transmission mechanism arranged on the casing of a blower and a start and stop mechanism. The pressure transmission mechanism is composed of a pipeline and an actuating cylinder connected with the pipeline. The start and stop mechanism is composed of a scale plate and a cover plate matched with the scale plate, wherein the actuating cylinder comprises a cylinder body connected with the pipeline, a plunger piston of which one end is rotationally connected with the cover plate, and a recoil mechanism matched with the plunger piston. In addition, the recoil mechanism is positioned in the cylinder body, and the plunger piston is arranged in the cylinder body. The utility model automatically and synchronously realizes that an air door is opened at the time of fuel supply, and the air door is closed at the time of shutdown or failure. In addition, the utility model can adjust air volume quantitatively and satisfy the burning of different oil masses. The utility model is safe.
Description
The utility model relates to a kind of device on the combustor, particularly relates to a kind of combustor air door automatic opening-closing.
Throttle setting on the existing combustor promptly only carries out simple open and close and adjusting roughly all by fixing air quantity design, does not have synchronous standard-sized sheet, contract fully, and the function of accurate quantification adjusting air quantity.Chinese patent CN88203589U discloses a kind of shunting adjustable multifunctional oil (gas) burner, wherein the adjusting of air quantity is to regulate plate washer by the air quantity that is installed in bellows Nei Cang porch to rotate realization, the air quantity of this device is regulated and is unfavorable for quantitatively regulating air quantity, and when closing secluding air fully.
The object of the present invention is to provide a kind of simple in structurely, open air door when can be implemented in fuel feeding synchronously automatically, close air door when left alone without help machine or fault, and can quantitatively regulate air quantity, satisfy the combustor air door automatic opening-closing of different oil masses burnings.
The utility model combustor air door automatic opening-closing is to realize like this, it comprises pressure transferred structure and the mechanism for opening/closing that is installed on the combustor Blower Housing, wherein, pressure transferred structure is by pipeline, is connected with pipeline and the pressurized strut that is fixed on the Blower Housing constitutes; Mechanism for opening/closing is by the scale plate that is installed on the Blower Housing, cooperates with scale plate and the cover plate that is rotatably connected on the Blower Housing constitutes.Cover plate is that part is solid, and part is hollow, and hollow position is provided with the less rib of spacing, is used to prevent aspirated foreign body.Pressurized strut comprises the cylindrical shell that is connected with pipeline, is arranged on the plunger that interior one end of cylindrical shell and cover plate are rotationally connected, generally connect with pin, and the return mechanism that is positioned at cylindrical shell and cooperates with plunger.Return mechanism can be made of the ring washer that is positioned at cylindrical shell, spring base and the spring and the sealing ring that cooperate with plunger.Scale plate generally is fixed on the Blower Housing by adjustment screw, by regulating adjustment screw, the rotation scale plate, can change the scale plate position, make the scale plate hollow position be blocked a part, reduced the area that hollow position can ventilate, to satisfy the burning of different oil masses by cover plate.In order to make the burning regulated quantity bigger, must be longer with pressurized strut and plunger design, with the cover plate of rotation dried scratching taken place for avoiding pressurized strut when the big stroke, the shape of cover plate lacks circle for well to be.
The operation principle of the utility model combustor air door automatic opening-closing is, after combustor starts, oil pump passes to pressurized strut by pipeline with oil pressure, promote the plunger motion in the cylindrical shell, and drive the cover plate inhour by pin and rotate to maximum position, expose the hollow position on the scale plate, promptly opened air inlet, finish automatic unlatching air door; When the left alone without help machine of combustor, pump pressure disappears, because the screen resilience of spring pushes up go back to the home position with plunger, drives cover plate simultaneously and gets back to the home position, and cover plate blocks the hollow position on the scale plate, promptly blocks air inlet, finishes closing automatically of air door.The adjustment process of its air quantity size is, unscrew the adjustment screw on the scale plate, inhour is rotated scale plate to certain position, screw adjustment screw, at this moment, even cover plate is opened into maximum position, the hollow position area that exposes on the scale plate is reduced, the intake of air inlet is reduced thereupon, reach the purpose of regulating air quantity.
The advantage of the utility model combustor air door automatic opening-closing is simple in structure, does not need electric device, opens air door when being implemented in fuel feeding synchronously automatically, close air door when left alone without help machine or fault, and can quantitatively regulate air quantity, and satisfy the burning of different oil masses, safe and reliable.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
