Description
Technical field
The utility model relates to a kind of air valve, is specifically related to the opening and closing device of air valve.
Background technology
The control of the ash bucket air valve that current grate-cooler equipment uses mainly contains following two kinds of modes:
One, adopt level-sensing device to control, because in ash bucket, temperature is high, level-sensing device must select expensive imported product when type selecting.But the particles hit ash material owing to falling, ash bucket constantly weares and teares, and shortens its service life.Further, level-sensing device is changed cumbersome, and because it is arranged on, air valve is inner so replacing is got up very difficult.
Two, adopt double-layer electric turnover panel, the disadvantage of this scheme is to consume energy and turnover panel easy to wear.This device only considered lock wind function, as long as start, motor will not stop to drive upper and lower turnover panel alternately to open, and does not consider whether hopper has material or have how many material, and therefore energy consumption is higher.Secondly, turnover panel does not stop to rub with material, and turnover panel changes work capacity greatly, easily causes turnover panel to wear and tear.
Utility model content
For solving above-mentioned prior art Problems existing, the utility model proposes a kind of air valve, this air valve is started with from the weight of material and to be measured weight of material in the hopper air valve, by the opening and closing through PLC control system process by-pass valve control afterwards of the data measured, there is energy-conservation, handled easily, the advantage such as ease of maintenaince.
The technical solution of the utility model is achieved in that
A kind of air valve, comprise hopper, spoon type valve, PLC control system, V-type stressed member, gravity sensor, motor and driving device, the two ends, top of described V-type stressed member are fixed on described hopper madial wall, wherein one end is connected with described gravity sensor by pressing plate, described gravity sensor is arranged on the lateral wall of described hopper, and described gravity sensor one end, top with described V-type stressed member is connected through hopper side wall by described pressing plate; Described spoon type valve is positioned at described hopper, is positioned at the below of the bottom of described V-type stressed member bottom it, and the shank of described spoon type valve is fixed on the madial wall of described hopper; The shank of described spoon type valve is also connected with described driving device one end, and described driving device is positioned at outside described hopper, and is connected with described motor; Described PLC control system is with described gravity sensor and motor and is electrically connected.
Further, also comprise the first proximity transducer and the second proximity transducer, described first proximity transducer and described second proximity transducer are all positioned at above described hopper lateral wall, and are positioned at the corresponding position of described spoon type valve, are all electrically connected with described PLC control system.
Further, described driving device is drive link.
Further, described first proximity transducer and described second proximity transducer are inductive pickoff, capacitance-type sensor, hall sensor, electro-optical pickoff, pyroelectric sensor or linear proximity transducer.
The beneficial effects of the utility model:
Air valve of the present utility model is connected with gravity sensor by V-type stressed member, when material drops on V-type stressed member, the weight signal of material is passed to PLC control system by gravity sensor, PLC control system sends signal control motor open and close, thus control the motion of driving device, and then drive the opening and closing of spoon type valve.Further, and be provided with and reach position and close the proximity transducer that puts in place to guarantee that valve switch accurately puts in place.
