Abstract
The utility model discloses a smoke flow control valve which is installed in a smoke discharging port of an elbow type chimney cap. The smoke flow control valve comprises two pinions, a central pivot tube, an adjusting draw bar, a pin, a spring, a bearing spring nut, an upper fixing bolt and a lower fixing nut. Through match of an oxygen adjustment function, discharging speed and discharging amount of smoke are selected, adjusted and controlled, so that collection and utilization of energy of a stove are achieved. Therefore, the purposes of heat preservation of a cavity of an earthen bed and control of burning speed of fuel and releasing speed of energy are achieved.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of flue gas flow control valve.
Background technique
Burning faggot or coal is one of principal mode of the most of people's productive life of northern China, and application area is very extensive.Yet in the fume emission process, prior art can only artificially promote the increasing of its mass rate of emission and discharge amount mostly, generally do not possess at the flue of a kang need to be incubated, the release rate working efficiency too fast, fume extractor of the velocity of combustion of fuel and energy surpasses under the situation of desirable demand and cooperates the accent oxygen function of cooking stove to bring into play the function that it reasonably selected, regulates and controlled fume emission speed and discharge amount effectively.
The model utility content
The utility model provides a kind of and has selected, regulates and mass rate of emission and the discharge amount of control flue gas realize the flue gas flow control valve that the cooking stove energy acquisition utilizes by the accent oxygen function that can cooperate cooking stove according to people's needs at any time, with the purpose of the release rate of the velocity of combustion that reaches flue of a kang insulation, control fuel and energy.
The utility model is achieved through the following technical solutions: a kind of flue gas flow control valve, it is characterized in that, this control valve comprises two pinions, maincenter pipe, regulating tie bar, pin, spring, bearing spring nut, goes up fixing bolt, following set screw nut, described two pinions are made by corrosion-resistant, on-deformable sheetmetal, be the semicircle structure, each semicircle pinion all is interrupted on its diameter and is provided with the two sections straight tube, and symmetry has two penetrating spiral chutes that direction is opposite respectively on the hypomere straight tube.
Further, external diameter when described regulating tie bar upper end is provided with diameter less than the maincenter bore and more than or equal to the spring pressure maximum also has the cylindrical section of two penetrating pin mounting holes, internal diameter when the diameter of described cylindrical section bottom pull bar does not have pressure less than spring, described pull bar lower end have the mounting hole of connection " rope tensioner " extension spring.
Further, the upper end of described maincenter pipe has the internal thread that is complementary with last fixing bolt, and the lower end has the outside thread that is complementary with following set screw nut and bearing spring nut, and the middle and lower part symmetry of described maincenter pipe has two penetrating straight line pin rail slots.
Further, the external diameter of described spring is less than the internal diameter of maincenter bore, the spring external diameter greater than the regulating tie bar hypomere, and the elastic force of spring is less than or equals the pulling force of " rope tensioner ".
Further, described bearing spring nut is a penetrating hole nut and is connected with maincenter pipe lower end screw thread coupling, described penetrating hole nut major part has screw thread, and small part does not have screw thread, the internal diameter the when internal diameter in unthreaded portion hole is less than or equal to spring and does not have pressure and greater than the external diameter of regulating tie bar hypomere.

Embodiment
By following description to embodiment; to help public understanding the utility model more; but can't the specific embodiment that the claimant is given be considered as the restriction to technical solutions of the utility model, any definition to parts or technical characteristics changes and/or overall structure is done form but not the conversion of essence all should be considered as protection domain that the technical solution of the utility model is limited.
As shown in Figures 1 to 4, the utility model is made of two pinions 3 and 7, maincenter pipe 4, regulating tie bar 8, pin 6, spring 12, bearing spring nut 11, last fixing bolt 1 and following set screw nut 9.Two pinion straight tubes 7 are socketed on the maincenter pipe 4, maincenter pipe upper end internal thread 2 and lower end outside thread 10 are respectively by two " flue gas flow control valve " mounting holes about the bending head type chimney cowl, using fixing bolt 1 and following set screw nut 9 screws in the smoke exhaust port that is vertically fixed on " bending head type chimney cowl ", regulating tie bar 8 penetrates in the maincenter pipe 4 from below, penetrating straight line pin rail slot 5 by pin 6 and maincenter pipe hypomere and two pinions 3 and 7 spiral chute are slidingly connected, spring 12 is socketed on the regulating tie bar 8, to push up the cylindrical section bottom of regulating tie bar 8 at the natural length of off working state lower spring 12, under to prop up bearing spring nut 11, two pinions 3 and 7 are that semicircle is plate shaped, dull and stereotyped direction parallels with the smoke evacuation direction under off working state, the aperture 13 of regulating tie bar 8 lower ends is connected with the extension spring of " rope tensioner " coupling and the pulling force from " rope tensioner " can be passed through regulating tie bar 8 when needed, the straight line pin rail slot 5 of pin 6 and maincenter pipe 4 is delivered on two pinions 3 and 7, making two pinions 3 and 7 axle center with maincenter pipe 4 is that the action that the likeness in form sparrow circles in the air is done in the center of circle under the effect of spring 12, thereby make two pinions 3 and 7 and the smoke evacuation direction between 0-90 degree scope, revolve in-migration and reach selection, regulate and control the purpose of fume emission speed and discharge amount, closely realize fully cooperating effectively and bringing into play the variation of cooking stove functional mapping, flue of a kang insulation, the velocity of combustion of control fuel and the release rate of energy make the collection utilization maximization of energy, rationalize.
Certainly; the utility model can also have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain that the technical solution of the utility model limits.
