The projection of described floating drum is spherical.
Employing the present invention have the following advantages: 1, simple in structure, element is few; 2, do not have easily damaged parts, improved reliability; 3, simple, convenient.
(4) description of drawings
Fig. 1 is a structural representation of the present invention
(5) embodiment
With reference to accompanying drawing, a kind of Car Steam Powered Condensate Recovering Pump, include the pump housing 2, pump cover 8, described pump housing bottom is provided with the liquid entering hole that is communicated with inlet valve group 1, the liquid outlet that is communicated with outlet valve group 9, also include the magnetic force reversing arrangement, described magnetic force reversing arrangement includes magnet 7, lower magnet 5, changeover valve core 6, reversing bar 4 and floating drum 3; Described pump cover 8 is provided with valve pocket, described upward magnet 7, lower magnet 5 are separately fixed at the top and bottom of described valve pocket, described pump cover 8 tops are provided with steam-expelling port 14, described pump cover 8 belows are provided with steam inlet 10, described changeover valve core 6 places in the described valve pocket slidably, described steam inlet 10, steam-expelling port 14 pass through changeover valve core 6 switched conductive with described valve pocket, are fixed with described reversing bar 4 on the described changeover valve core 6; Described floating drum 3 is positioned at the pump housing 2, and described floating drum 3 upper ends are provided with the projection 11 of passing described changeover valve core 6, and described reversing bar 4 runs through the through hole in floating drum 3 center portions, and the bar shoulder 12 of described reversing bar 4 bottoms is positioned at floating drum 3 lower ends.The described pump housing 2 inboards are provided with the guide pad 13 of floating drum 3.Described changeover valve core 6 is a hollow structure.Described floating drum 3 is the hollow floating drum.Described changeover valve core 6 is cylindrical, and described upper and lower magnet is the annular that matches.The projection 11 of described floating drum is spherical.
When condensed fluid enters the pump housing 2 by inlet valve group 1, at this moment, outlet valve group 9 is closed.Along with liquid progresses into, the liquid level in the pump housing 2 is more and more higher, and the suffered buoyancy of floating drum 3 is also just increasing, when buoyancy increases to deadweight greater than floating drum 3, floating easy in the pump housing the uniting under the guiding of guide pad 13 and reversing bar 4, steadily upwards float.Move at floating drum 3 top projections 11 and to touch changeover valve core 6, during interactional magnetic force sum, changeover valve core 6 just begins to break away from ring magnet 5 down between buoyancy further increases to greater than the deadweight of changeover valve core 6, floating drum 3 and changeover valve core 6 and following ring magnet 5; Because magnetic force between two articles and square being inversely proportional to of distance between them, like this, magnetic force just sharply descends again, and changeover valve core 6 quickens to move upward up to last ring magnet 7 one ends; This moment, steam inlet 10 was opened, and steam-expelling port 14 is closed, and band presses gas to be entered in the pump housing 2 by steam inlet 10, and condensed fluid is discharged from outlet valve group 9, and inlet valve group 1 is oppositely closed and stoped condensed fluid to pour in down a chimney in this process.Along with the discharge of condensed fluid, the liquid level in the pump housing 2 reduces, and floating drum 3 suffered buoyancy float to following in the pump housing 2 less than its deadweight, and in the starting stages that floating drum 3 floats downwards, reversing bar 4 is not subjected to power and keeps state of rest.When floating drum floats to a certain position 3 times, will apply a downward pulling force to commutation spool 6 by reversing bar 4 bottom bar shoulder 12.If during the difference that the difference of the gravity of floating drum 3 and its suffered buoyancy is conducted oneself with dignity greater than the magnetic force between changeover valve core 6 and the last ring magnet 7 and changeover valve core 6, changeover valve core 6 just can break away from ring magnet 7 and move downward fast to following ring magnet 5 one ends, and motion commutation mechanism is identical when moving upward.Steam-expelling port 14 is opened and steam inlet 10 is closed, and gases are discharged through steam-expelling port 14 by the passage on the changeover valve core 6 in the pump housing 2.Floating drum 3, inlet valve group 1, outlet valve group 9, changeover valve core 6 are returned to initial suction condition, finish an operation cycle, and circulation can realize that just condensed fluid reclaims the work functions of pump so repeatedly.
