A collapsible floating apparatus for controlling a valve includes a floating device and a collapsible lever. The collapsible lever includes a first member rotatably coupled to the valve, and a second member attached to the floating device at one end and rotatably coupled to the first member adjacent another end. The apparatus has a retracted position for shipping and storage, and operational positions. In the position, the second member, or the first and second members together, are brought adjacent to the valve. In operational positions, the first and second members act as a single lever to relay the buoyancy of the floating device drives to the valve. An adjusting member is provided for adjusting a relative position or angle between the first and second members, which in turn adjusts a water level.

The invention discloses a water tank of a water purifying machine with an automatic circulating control function and the water purifying machine. The water tank of the water purifying machine comprises a water storage bin of the water tank, a control bin of the water tank, an upper cover plate, flow guide pipes of the water storage bin and the control bin, a floating ball valve and an automatic water level valve, wherein the control bin of the water tank is arranged outside the water storage bin of the water tank; the upper cover plate is used for sealing the upper ends of the water storage bin of the water tank and the control bin of the water tank; the flow guide pipes of the water storage bin and the control cabin are arranged between the upper ends of the water storage bin of the watertank and the control bin of the water tank, and are used for guiding the water in the water storage bin of the water tank to flow into the control bin of the water tank; a floating ball of the floating ball valve is positioned under the middle part of the interior of the water storage bin of the water tank, and a valve body of the floating ball valve is arranged between the water storage bin of the water tank and the control bin of the water tank, and is used for controlling the communication and cutoff of the water storage bin of the water tank and the control bin of the water tank; the automatic water level valve is arranged at the upper part of the interior of the control bin of the water tank, the pure water is introduced via a water inlet of the automatic water level valve, and a water outlet of the automatic water level valve is positioned in the water storage bin of the water tank. The water tank has the advantage that under the cooperation of the water storage bin, the controlbin, the automatic water level valve and the floating ball valve, the water injection of the water purifying machine can be automatically and circularly controlled without additional arrangement of any electronic component.

The invention relates to a drip irrigation device, in particular to a zero-pressure drip irrigation system which is composed of a water storage tank, a balance water tank, a water supply pipe, water diversion branched pipes, water diversion capillaries and capillary drippers. Each capillary dripper is composed of a dripper cover and a capillary bundle which is mounted in a bayonet of the dripper cover, each dripper cover is mounted at the upper end of the corresponding water diversion capillary, the lower end of each water diversion capillary is connected onto a branch port of the corresponding water diversion branched pipe, the lower end of each capillary bundle extends into the corresponding water diversion branched pipe through in-pipe space of the corresponding water diversion capillary while the upper end of the same is led out of the bayonet of the corresponding dripper cover, an inlet end of each water diversion branched pipe is connected onto a branch port of the water supply pipe, an inlet end of the water supply pipe is connected onto a supplied water output port of the balance water tank, a floating ball valve is connected into the balance water tank, and an inlet end of the floating ball valve is connected onto a water outgoing port of the water storage tank. A capillary principle is utilized to achieve the objective of drip irrigation, the water supply pipe does not need pressure, and the drippers cannot be blocked, so that equipment purchasing expense and running expense are lowered, and drip irrigation technology is enabled to be inexpensive.

The invention discloses a heat pipe type energy-saving central air-conditioning cooling system. The central air-conditioning cooling system comprises a cooling tower and is characterized in that a heat pipe device is installed in a case of the cooling tower, cool air inlets are mounted on two sides of the case of the cooling tower, a hot air outlet is arranged at the top of the case of the cooling tower, and an induced draft fan is mounted at the hot air outlet; the heat pipe device is a spiral heat pipe, a forest-type heat pipe or a branch-shaped heat pipe, the evaporation section of the heat pipe contacts with a working solution in a junction box, the cooling section contacts with cool air induced by the cool air inlet, hot air formed by the heat pipe after heat is absorbed by the cool air is discharged out of the cooling tower through the induced draft fan, and the heat pipe introducing a heat source form a heat exchanger of a refrigerating unit is connected to the working solution in the junction box; and a water tray in the cooling tower is equipped with a circular sprayer or atomizer, an electric pump is started to enable water in the water tray to be sprayed through the sprayer or atomized through the atomizer, the water in the water tray is supplied by a water supply pipe which is connected with a tap water pipe outside, and the water volume is controlled by a float valve device. The heat pipe type energy-saving central air-conditioning cooling system has the advantages of being water-saving, small in occupied building space and silent in operation.
