When no water exists in the water accumulating barrel, the floater is located at the lowest position of the water accumulating tank, the positive pressure balance cavity is isolated from the external atmosphere, the negative pressure balance cavity is communicated with the gas pipe, the air pressure in the water accumulating barrel is the same as the air pressure in the gas pipe, the one-way water inlet valve is opened, and the accumulated water in the gas pipe enters the water accumulating barrel through the one-way water inlet valve. The float continuously rises along with the continuous rising of the water level in the water accumulation barrel, and stops rising when the float is contacted with the valve core of the control valve. Under the action of buoyancy generated by the floater, the positive pressure balance cavity is communicated with the external atmosphere through the linkage mechanism, so that the air pressure in the water accumulation barrel is the same as that of the external atmosphere, the one-way water inlet valve is closed, the one-way water outlet valve is opened, and the water discharging process is completed.
Therefore, in the prior art, the structure of the accumulated water drainage device is complex, the cost is high, and the installation and maintenance are also complex; in addition, if no negative pressure exists in the accumulated water pipeline, the accumulated water discharge can not be realized by adopting the existing accumulated water drainage device.

Fig. 3 is a schematic diagram of the automatic water discharger without the pressure difference in the second working state according to the invention. As shown in fig. 3, as the level of the accumulated water in the water accumulating tank 1 rises, the float 2 rises along the guide bar 3. The horizontal handle 21 of the float 2 pushes the rotating rod 911 to rotate so that the center of gravity of the weight 914 is located on a vertical line with the center of the L-shaped rod 913 while the rotating member 91 is in a horizontal state, i.e., the rotating member 91 is in a critically stable state. In the second working state of the automatic water discharger without the pressure difference, the water inlet valve 4 is opened, the atmospheric valve 6 and the water outlet valve 5 are closed, the air pressure in the water accumulating tank 1 is the same as the air pressure in the water accumulating pipe, and the water accumulating tank 1 continuously accumulates water.
Fig. 4 is a schematic diagram of the third working state of the automatic water discharger without the pressure difference according to the invention. As shown in fig. 4, the level of the accumulated water in the accumulated water tank 1 continues to rise, the float 2 continues to rise along the guide rod 3, and the horizontal handle 21 of the float 2 pushes the rotating rod 911 to rotate in a direction biased toward the translation member 92. When the rotating part 91 deviates from the critical stable state, the rotating part 91 rapidly rotates under the action of the weight 914, the horizontal handle 21 of the floater 2 is separated from the rotating rod 911, and the push rod 912 pushes the water inlet valve 4, so that the water inlet valve 4 is closed. Meanwhile, one end of the rotating rod 911 close to the translational component 92 pushes the vertical rod 921 to horizontally translate towards one side of the atmosphere opening 13 and the water outlet 12, the first balance rod 922 and the second balance rod 923 are driven by the vertical rod 921 to horizontally translate towards one side of the atmosphere opening 13 and the water outlet 12, the first balance rod 922 pushes the atmosphere valve 6 to be opened, and the second balance rod 923 pushes the water outlet valve 5 to be opened. In the third working state of the automatic water discharger without the pressure difference, the water inlet valve 4 is closed, the atmospheric valve 6 and the water outlet valve 5 are opened, the air pressure in the water accumulating tank 1 is equal to the air pressure of the external atmosphere, and accumulated water flows out to the outside through the water outlet 12 under the action of the gravity of the accumulated water.
Fig. 5 is a schematic diagram of the fourth operating state of the automatic water discharger without the pressure difference according to the invention. As shown in fig. 5, as the accumulated water in the water accumulating tank 1 flows out, the accumulated water level continuously drops, and the float 2 also drops along the guide rod 3. The horizontal handle 21 of the float 2 pushes the bent portion of the L-shaped rod 913 of the rotating member 91 so that the rotating member 91 rotates toward the float 2 side, and when the center of gravity of the weight 914 and the center of the L-shaped rod 913 are positioned on the vertical line again, the rotating member 91 reaches the critical stable state again. In the fourth working state of the automatic water discharger without the pressure difference, the water inlet valve 4 is kept closed, the atmospheric valve 6 and the water outlet valve 5 are kept opened, accumulated water still flows out through the water outlet 12, and a circulation process is completed.
As the accumulated water level in the accumulated water tank 1 continues to drop, the float 2 also continues to drop along the guide rod 3, when the horizontal handle 21 of the float 2 touches the elbow part of the L-shaped rod 913 of the rotating component 91, the horizontal handle 21 of the float 2 drives the rotating component 91 to continue rotating towards one side of the float 2, the rotating component 91 deviates from the critical stable state, and returns to the first working state of the non-differential pressure automatic water discharger shown in fig. 2, and the next cycle process is started.
In a word, when the automatic water discharger without the pressure difference starts to operate, the water outlet valve and the atmospheric valve are closed, the water inlet valve is opened, at the moment, the air pressure in the water accumulation tank is the same as the air pressure in the water accumulation pipe, and accumulated water in the water accumulation pipe enters the water accumulation tank under the action of gravity. The float rises along with the rise of the water level of the accumulated water in the accumulated water tank, the horizontal handle of the float pushes the rotating rod to rotate towards one side of the translation component, and when the float rises to a certain height, namely the water level of the accumulated water reaches a certain height, the ejector rod of the rotating component pushes the inlet valve to close the inlet valve; meanwhile, the rotating component pushes the translation component, and the translation component enables the atmosphere valve and the water outlet valve to be opened by translating towards the atmosphere port and the water outlet port. After the atmospheric valve is opened, the air pressure in the water accumulation tank is the same as that of the outside atmosphere, so that accumulated water in the water accumulation tank flows out through the water outlet under the action of gravity. In the invention, the air pressure in the water accumulating pipe and the external air pressure can be equal or unequal. Therefore, the automatic water discharger without the pressure difference can realize accumulated water discharge regardless of the existence of negative pressure in the accumulated water pipeline; moreover, the structures of the rotating part and the translation part in the invention are simple and easy to realize, so that the invention also has the characteristic of low cost.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
