Abstract
The invention discloses an active dry burning prevention balanced reservoir device comprising a balanced reservoir, a microswitch and a second magnet. The balanced reservoir is internally provided with a floating ball vertically movable along with water level. A first magnet is fixed at the lower end of the floating ball. The microswitch is accommodated in an accommodating chamber under the balanced reservoir and provided with a trigger plate outside a shell and a circuit switch in the shell. The circuit switch is driven by the trigger plate and electrically connected with a control system of the active dry burning prevention balanced reservoir device. The second magnet is fixedly connected with the trigger plate of the microswitch and close to the lower end face of the balanced reservoir. The second magnet corresponds to a bottom dead center of the first magnet. In case of lack of water in the balanced reservoir, under action of the first magnet, the second magnet triggers the circuitswitch through the trigger plate, and the control system sends a power-off command to the active dry burning balanced reservoir device after receives the signal. In this way, through match of the magnets and the microswitch, the control system timely receives water lack information and actively powers off.
Description
Technical field
The present invention relates to water treatment field, particularly one initiatively anti-dry balanced reservoir device.
Background technology

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
As shown in Figure 2, active anti-dry balanced reservoir device of the present invention comprises the water container 5 at calandria 10, balanced reservoir assembly and the water source, upstream as balanced reservoir assembly, is provided with calandria water inlet pipe 9 between balanced reservoir assembly and calandria 10.
Balanced reservoir assembly comprises balanced reservoir 1, be arranged on the internal layer shell 3 of balanced reservoir 1 inside and ball float 2 and the current controlled between balanced reservoir 1 and water container 5 opens and the sealing interrupted bores 4.The housing that balanced reservoir 1 is formed is made up (as: PP or polyethylene) of the material that rigidity is lower, ball float 2 comprises lumen 22, is symmetricly set on floating chamber 21 and the floating ball cap 23 of lumen 22 both sides, the upper opening of lumen 22, and lower than the bottom in floating chamber 21 bottom it, the floating top in chamber 21 is connected with the top of lumen, but there is spacing between the sidewall of floating chamber 21 and lumen 22.As shown in Figure 2, floating chamber 21 is cup-shaped.Float the shape that chamber 21 also can be other, as spherical.The lower surface of floating ball cap 23 is provided with the projection with the opening adaptation of floating chamber 21 and lumen 22, and makes floater seal by hot plate welding.
As shown in Figure 2, internal layer shell 3 by the material that rigidity is higher make (as, ABS plastic), be fixedly installed in balanced reservoir 1, ball float 2 is sleeved in internal layer shell 3, internal layer shell 3 comprises the guide rail 31 of upper and lower opening and is symmetricly set on the directed cavity 32 of guide rail 31 both sides, guide rail 31 extends respectively up and down from the bottom of internal layer shell 3, the top of guide rail 31 is lower than the top of internal layer shell 3, the appearance and size of guide rail 31 and lumen 22 adaptation, and the bottom of lumen 22 is sleeved in guide rail 31, provides guide effect for lumen 22 and be interconnected with balanced reservoir 1.When lumen 22 moves up and down in guide rail 31, floating chamber 21 moves up and down in directed cavity 32.The top of internal layer shell 3 is provided with the annular cover 33 extended to center by the outer wall of internal layer shell 3, prevents the lumen 22 of ball float 2 from deviating from guide rail 31 under buoyancy, makes guide rail 31 lose guide effect.Like this, ball float 2 can move up and down under the guiding of guide rail 31 in internal layer shell 3, for ball float 2 provides applicable space, avoids the too high or too low fault caused in ball float position.
Position corresponding with lumen 22 on floating ball cap 23 is provided with groove 231, and bottom and the groove 231 of sealing cone 4 are adaptive, and the bottom of sealing cone 4 is arranged in groove 231 by interference fit, and the top of sealing cone 4 is taper.Preferably, the top of groove 231 protrudes from the end face of floating ball cap 23, makes to seal cone 4 longer with the interference fit part of groove 231, installs more stable; And sealing cone 4 is provided with the flange 41 coordinated with the end face of groove 231, improves the tolerance of sealing cone to the impulse force of current, the service life of sealing cone can be extended.Equilibrium water case lid 11 is removably mounted on balanced reservoir 1, and equilibrium water case lid 11 is provided with and the balanced reservoir water inlet pipe 52 of water container 5 and the suitable tube connector 111 of balanced reservoir muffler 51.Taper upper end and the tube connector 111 of sealing cone 4 are adaptive.
The below of balanced reservoir 1 is provided with the container cavity holding microswitch 8, microswitch 8 comprises the housing of insulation, the shake-up plate 81 of hull outside setting and enclosure interior by the contactor touching plate 81 driving, contactor is connected with the control system circuit of active anti-dry balanced reservoir device the other end touching plate 81 and is fixedly connected with the second magnet 7, second magnet 7 is near the lower surface of balanced reservoir 1, the bottom of lumen 22 is fixed with the first magnet 6 with ball float movement, second magnet 7 is corresponding with the lower dead center of the first magnet 6.
Balanced reservoir 1 is provided with waterline 13, when the water level of balanced reservoir exceedes waterline 13, ball float 2 moves upward leading of guide rail 31 downward vertically due to buoyancy, the taper upper end of sealing cone 4 is inserted in tube connector 111, when seal cone 4 and tube connector 111 abut completely cannot rise time, sealing cone 4 serves sealing function, and balanced reservoir 1 stops water inlet, prevents the fault because hypervolia in balanced reservoir causes.When the water in balanced reservoir 1 transfers to the water level decreasing making balanced reservoir 1 in calandria 10 gradually, during lower than waterline 13, ball float 2 declines because buoyancy diminishes, first magnet 6 constantly declines along with ball float 2, active force is produced between first magnet 6 and the second magnet 7, second magnet 7 is because of stressed generation movement, shake-up plate 81 is driven to move, Triggering circuit switch, cut-offing instruction is sent to anti-dry balanced reservoir device after control system receives the signal of contactor, cut off heater circuit, prevent calandria 10 dry combustion method.
Active anti-dry balanced reservoir device of the present invention is provided with floating ball cap on ball float, is got up by floater seal, avoids the not good enough adverse consequences caused of sealing cone sealing property that water inlet buoyancy in ball float reduces to cause; First magnet, the second magnet pass to control system in time with the lack of water information making balanced reservoir that coordinates of microswitch, and are initiatively cut off the electricity supply by control system, exceed power-off again after the upper limit without the need to by the time limitting the temperature of warm resistance; The internal layer shell be made up of the material that rigidity is higher can be guided ball float and be moved up and down exactly, avoids inner housing occur large distortion and affect the kinematic accuracy of ball float.
Be only a specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
