Detailed Description
The embodiment of the utility model comprises the following steps: as shown in figure 1, the device comprises a water storage barrel 1, wherein the water storage barrel 1 is connected with a negative pressure balance pipe 11, the negative pressure balance pipe 11 is connected with an air outlet pipe of a gas-water separation device 9, and the gas-water separation device 9 is connected with a gas pipe 10; the water storage barrel 1 is connected with a water outlet pipe 8 of a gas-water separation device 9 through a water inlet valve 7; an air inlet and outlet valve 6 is arranged at the top of the water storage barrel 1; a floating ball 2 is arranged in the water storage barrel 1, the floating ball 2 is connected with a top rod 3, and the top rod 3 is connected with an air inlet and outlet valve 6; the water outlet valve 4 is arranged at the lower part of the water storage barrel 1.
The water storage barrel 1 is connected with a negative pressure balance pipe 11 through a negative pressure balance control valve 5.
The utility model utilizes the floating ball to drive the ejector rod to lift, controls the actions of the air inlet and outlet valve, the water inlet valve and the water outlet valve, and realizes automatic water storage or water discharge. The working principle is as follows:
the water discharge state is shown in fig. 2. The floating ball 2 pushes the ejector rod 3 upwards to act on the air inlet and outlet valve 6 under the buoyancy action of water, the air inlet and outlet valve 6 is opened to admit air, air enters the water storage barrel 1, when the air inflow is larger than the air suction amount of the negative pressure balance pipe 11, the water inlet valve 7 is closed under the action of air pressure, meanwhile, the water outlet valve 4 is opened under the action of water pressure, water in the water storage barrel 1 flows out, and water drainage of the water storage barrel is achieved.
The water inlet state is shown in fig. 3. Along with the continuous outflow of water in the water storage barrel 1, the floating ball 2 descends continuously, and the ejector rod 3 descends simultaneously. When the ejector rod descends to the state that the air inlet and outlet valve 6 is closed, the negative pressure balance pipe 11 (the negative pressure balance pipe control valve 5 is in a normally open state) continuously pumps air in the water storage barrel 1 by utilizing the negative pressure of the pumping pipe, so that the interior of the water storage barrel 1 is in a negative pressure state. When the negative pressure in the water storage barrel is balanced with the negative pressure in the gas pipe, the water inlet valve 7 is opened, and then the water enters a water inlet state; meanwhile, the water outlet valve 4 is closed because the water storage barrel 1 is in a negative pressure state.
When the water storage barrel 1 is in a water inlet state, the floating ball 2 rises along with the rise of the water level, after the floating ball rises to a certain height, the ejector rod 3 acts on the air inlet and exhaust valve 6 upwards, the water discharging state is repeated, the circulation is repeated, automatic water inlet and water discharge are realized, the gas pipe is normally pumped, and potential safety hazards are eliminated.
