Fig. 2 is the first working state schematic representation of automatic water discharge device free from pressure difference of the present invention.As shown in Figure 2, when in water tank 1 during without ponding, float 2 is positioned at the bottommost of water tank 1, and rotary component 91 is partial to float 2 one sides under the effect of pouring weight 914, and swingle 911 is supported on the Level handle 21 of float 2 near one end of float 2 one sides.Affect inlet valve 4 one end at the fixing rope of swingle 911 and push rod 912 joints, inlet valve 4 is opened, and the ponding in water accumulation pipe enters water tank 1 by water intake 11.Simultaneously, under the traction of the fixing rope of swingle 911 central spot, montant 921 drives the first cross bar 922, the second cross bar 923 to move horizontally to float 2 one sides, the first cross bar 922, the second cross bar 923 affect respectively atmos-valve 6, outlet valve 5 by rope, and atmos-valve 6, outlet valve 5 are all closed.Under the first working state of automatic water discharge device free from pressure difference of the present invention, the air pressure in water tank 1 is identical with the air pressure in water accumulation pipe, and water tank 1 is stored ponding.
Fig. 3 is the schematic diagram of automatic water discharge device free from pressure difference the second working state of the present invention.As shown in Figure 3, along with the rising of the water accumulation level in water tank 1, float 2 rises along guide rod 3.The Level handle 21 of float 2 promotes swingle 911 and rotates, and makes the center of gravity of pouring weight 914 and being centered close on a vertical curve of L-type bar 913, and at this moment rotary component 91 is in level, that is, rotary component 91 is in critical stable state.Under the second working state of automatic water discharge device free from pressure difference of the present invention, inlet valve 4 is opened, atmos-valve 6, outlet valve 5 closures, and the air pressure in water tank 1 is identical with the air pressure in water accumulation pipe, and water tank 1 continues ponding.
Fig. 4 is the schematic diagram of automatic water discharge device free from pressure difference of the present invention the 3rd working state.As shown in Figure 4, the water accumulation level in water tank 1 continues to raise, and float 2 continues to rise along guide rod 3, and the Level handle 21 of float 2 promotes the direction rotation of swingle 911 to deflection translation parts 92.When rotary component 91 departs from critical stable state, under the effect of pouring weight 914, rotary component 91 fast rotational, the Level handle 21 of float 2 separates with swingle 911, and push rod 912 promotes inlet valve 4, makes inlet valve 4 closures.Simultaneously, swingle 911 promotes montant 921 to atmospheric air port 13 and water outlet 12 1 side horizontal translations near one end of translation parts 92, the first balancing pole 922, the second balancing pole 923 under the drive of montant 921 to atmospheric air port 13 and water outlet 12 1 side horizontal translations, the first balancing pole 922 promotes atmos-valve 6 and opens, and the second balancing pole 923 promotes outlet valve 5 and opens.Under the 3rd working state of automatic water discharge device free from pressure difference of the present invention, inlet valve 4 closures, atmos-valve 6, outlet valve 5 are opened, and the air pressure in water tank 1 equates with the air pressure of outside atmosphere, under the Action of Gravity Field of ponding, ponding flows out to outside by water outlet 12.
Fig. 5 is the schematic diagram of automatic water discharge device free from pressure difference of the present invention the 4th working state.As shown in Figure 5, along with the outflow of ponding in water tank 1, water accumulation level constantly declines, and float 2 also declines along guide rod 3.The Level handle 21 of float 2 promotes the elbow part of the L-type bar 913 of rotary component 91, make rotary component 91 to float 2 one sideway swivels, when center of gravity and the L-type Gan913 center of pouring weight 914 are positioned on a vertical curve again, rotary component 91 reaches critical stable state again.Under the 4th working state of automatic water discharge device free from pressure difference of the present invention, inlet valve 4 remains closed, and atmos-valve 6, outlet valve 5 stay open, and ponding still flows out by water outlet 12, completes a cyclic process.
Along with the continuation of the water accumulation level in water tank 1 declines, float 2 also continues to decline along guide rod 3, in the time that the Level handle 21 of float 2 touches the elbow part of the L-type bar 913 that arrives rotary component 91, the Level handle 21 driven rotary parts 91 of float 2 continue to float 2 one sideway swivels, rotary component 91 departs from critical stable state, the first working state of returning to automatic water discharge device free from pressure difference of the present invention as shown in Figure 2, has started cyclic process next time.
In a word, when automatic water discharge device free from pressure difference of the present invention brings into operation, outlet valve, atmos-valve are closed, and inlet valve is opened, and at this moment, the air pressure in water tank is identical with the air pressure in water accumulation pipe, and the ponding in water accumulation pipe, under the effect of gravity, enters water tank.Float rises along with the rising of water accumulation level in water tank, and the Level handle of float promotes swingle to one sideway swivel of translation parts, in the time that float rises to certain altitude,, when water accumulation level reach a certain height, the push rod of rotary component promotes inlet valve, and inlet valve cuts out; Meanwhile, rotary component promotes member of translational, and member of translational is by impelling atmos-valve and outlet valve to open to atmospheric air port and the translation of water outlet side.After atmos-valve is opened, the air pressure in water tank is identical with the air pressure of outside atmosphere, makes ponding in water tank under Action of Gravity Field, flows out by water outlet.In the present invention, the air pressure in water accumulation pipe can equate with external pressure, also can not wait.Therefore,, no matter whether there is negative pressure in ponding pipeline, automatic water discharge device free from pressure difference of the present invention all can be realized ponding discharge; And all fairly simple and easily realizations of the structure of rotary component and translation parts, make the present invention also have feature with low cost in the present invention.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
