Abstract
The utility model relates to a damping servo flow valve for settling the problems of short circuit and red flow of a cooler. The utility model adopts a technical solution that the damping servo flow valve comprises a valve body. The utility model is characterized in that: the upper end in the valve body is connected with a compression spring; the compression spring is connected with a valve plate; and a body which forms the valve body is provided with a plurality of ventilation holes. The damping servo flow valve is provided in an air supplying system of a cement clinker grate type cooler for controlling and adjusting the cooling air volume which passes through a grate bed. Through the automatic adjustment of the damping servo flow valve, the cement clinker on the grate bed obtains a constant air current and the cooler obtains a higher cooling efficiency thereby saving system energy.
Description
Technical field
The utility model relates to a kind of Flow valve, relates to a kind of damping servo flow metered valve that is used on the cement clinker grate cooler air feed system particularly.
Background technique
For cement clinker cooler, at grate cooler, the bed cloth present situation of combing is: size separation, thickness inequality, thereby easily cause " short circuit " of cooling air, grog " Red River " appears on the bed of combing.
Be used for the Flow valve on the grate cooler at present, product structure mainly contains: link plate formula and steel ball type.
Hanging plate valve is to utilize the link plate own wt as the damping element.1. dust adhesion can take place on link plate and have influence on the variation of weight in long-term use.2. the hook of link plate generation wearing and tearing and card bump.Sensitivity and precision that the both can have influence on control and adjust.
The steel ball type valve is to have disposed three steel balls of Different Weight as the damping element, and its variation is non-linear, and control and adjustment also suddenly change, so the sensitivity of its control and adjustment and precision are unfavorable.
Summary of the invention
For " short circuit " and " Red River " problem that solves Coolers, the utility model provides a kind of and can regulate automatically, make the clinker on the bed of combing obtain constant air-flow, make Coolers obtain higher cooling effectiveness, thus the damping servo flow metered valve of the system of the saving energy.
To achieve these goals, the technical solution adopted in the utility model is: a kind of damping servo flow metered valve, comprise valve body, and it is characterized in that the upper end connects pressure spring in the valve body, pressure spring connects valve plate, and the body that constitutes valve body is provided with some vents.
The design of the utility model damping servo flow metered valve is based on simple physics law and aerodynamic principle, is to utilize the linear resistance of spring as the damping element, has avoided weight change and wearing and tearing, the sensitivity and the precision that have influence on control and adjust.Control and the sensitivity of adjusting and the linear change of precision have been realized simultaneously.
The valve body surface of the utility model damping servo flow metered valve has some vent holes according to certain rules.Because the pressure in the valve body can accurately react the resistance of the top bed of material, rely on the inside and outside pressure difference of valve body, valve plate moves up and down in valve body automatically.When the grog layer resistance increases (fines layer), cause by the bed of material cooling air quantity hour, valve plate is operation downwards automatically, increases vent area, is equivalent to make the grate plate resistance to reduce, at this moment the cooling air quantity by the bed of material will increase; When the grog layer resistance reduces (coarse fodder layer), when causing cooling air quantity by the bed of material big, valve plate is upwards operation automatically, reduces vent area, is equivalent to make the grate plate resistance to increase, and at this moment the but air quantity by the cold burden layer will reduce.When air pressure outside the valve body and spring pressure on the valve plate reach when equating, valve plate is in state of equilibrium, at this moment, and the valve opening degree that the valve plate present position is corresponding certain.When each valve plate on the cooling machine all was in state of equilibrium, whole cooling machine had just reached best air feed state.Like this, by the control of modulating valve, a grog layer of going up different units that guaranteed to comb all can obtain suitable cooling air volume.
The beneficial effects of the utility model are: the utility model is installed in the air feed system of cement clinker grate cooler, is used to control, adjust the cooling air quantity by the bed of combing.By the automatic adjusting of damping servo flow metered valve, make the clinker on the bed of combing obtain constant air-flow, make Coolers obtain higher cooling effectiveness, thus the system of the saving energy.
