Description

Poultry Drinker Water Supply Unit

Technical field

The utility model relates to a water supply device, in particular to an automatic water supply device for a poultry drinking fountain.

Background technique

Raising poultry in the prior art all needs to be equipped with drinking water vessel for poultry, especially large-scale farm, all is equipped with drinking water tank, when the water of drinking water tank is used up, replenishes water in water tank regularly again, its shortcoming is that : it needs artificially to replenish water continuously in the tank, which is cumbersome, and when the water in the tank decreases in addition, poultry will jump into the tank to pollute the tank.

Contents of the invention

The technical problem to be solved by the utility model is to aim at the deficiencies of the prior art, and propose a poultry waterer water supply device which keeps the water level in the water tank at a certain level all the time.

The technical problem to be solved in this practical model is achieved through the following technical solutions. A water supply device for poultry drinking fountains, which includes a drinking tank, is characterized in that: a water storage tank is arranged on the upper part of the drinking tank, and the bottom of the water storage tank is A water outlet pipe inserted into the water tank is provided, and a connecting pipe inserted into the water tank is arranged on the top of the water storage tank. The lower port of the connecting pipe located in the water tank is higher than the water outlet of the water outlet pipe. When there is water in the water storage tank, the water in the tank will flow into the drinking water tank through the outlet pipe, and the outside air will enter the upper part of the water storage tank through the connecting pipe. When the water level in the drinking water tank rises and seals the lower port of the connecting pipe, The outside atmosphere no longer enters the water storage tank, and at this moment the water in the tank will still flow to the drinking tank, while the air pressure in the tank begins to decrease, and the connecting pipe is pressed into a section of water column under the effect of the external atmospheric pressure. When the sum of the gas pressure and the liquid pressure in the tank is equal to the external atmospheric pressure, the water in the tank stops flowing and no longer fills the drinking tank. At this time, according to the principle of the connecting device, the height of the water column in the connecting pipe is consistent with the water height of the water storage tank. When the water level in the drinking tank drops to the point where the lower port of the connecting pipe is out of the water, the water in the connecting pipe will flow down due to gravity, and the air will enter the tank through the lower port of the connecting tube, so the water in the tank will start to fill the drinking tank again , the water in the box just repeats the phenomenon at the beginning.

The technical problem to be solved by the utility model can be further realized through the following technical solutions: open the water replenishment port on the top of the water storage tank, a sealing cover is provided at the water replenishment port, and a gate valve is provided at the water outlet connecting the water storage tank and the water outlet pipe , the gate valve is provided with a control valve rod downward, the control valve rod passes through the water outlet pipe downward, and a valve control float is installed at its lower end. When the water level in the drinking tank drops to the lowest water level, all the floats are exposed to the water surface, and the gate valve closes the water outlet under its own gravity. At this time, water can be replenished to the water storage tank through the replenishment port. After filling, the water flows into the drinking water tank from the connecting pipe. Sink (also can directly add water to drinking trough), when the water in the drinking trough reaches the highest water level line, immediately seal the water replenishing port with sealing cap. Under the condition that the water level in the drinking tank does not drop, the connecting pipe is sealed by water, and the outlet pipe is also sealed by the gate valve. At this time, the control valve float lifts the gate valve under the buoyancy of the water to open the water outlet channel.

The technical problem to be solved by the utility model can also be further realized through the following technical scheme, a limit rod is installed on the control valve rod between the control valve float and the water outlet pipe.

The technical problem to be solved by the utility model can be further realized through the following technical solutions. It is also provided with a valve-controlled water tank. The ports are located in the control valve water tank.

The technical problem to be solved by the utility model can also be further realized through the following technical solutions, the water supply port is connected with the running water pipe through a water tap.

The technical problem to be solved by the utility model can be further realized through the following technical solutions. The valve stem of the faucet at the water supply port is hinged downward with a vertical rod, and a faucet float is connected to the bottom of the vertical rod, and the faucet float is inserted into a float chamber. The float chamber communicates with the water tank.

Compared with the prior art, the utility model utilizes the principle of the connecting device to continuously replenish water into the drinking tank through the automatic adjustment and balance of the air pressure inside and outside the water storage tank, so that the water level in the water tank is always kept at a certain level. It reduces the trouble of artificial water replenishment, and at the same time can make the water tank clean and hygienic, reducing pollution.
