Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment:
The structural schematic diagram of the utility model as shown in Figure 1, the utility model negative pressure drainage device, include negative-pressure cup
1, water compensating valve 2, exhaust-valve 3, drainage tube 4, outlet pipe 5, blowdown valve 6, wherein negative-pressure cup 1 is closed tank body, water compensating valve 2 and emptying
Valve 3 is installed in the top of negative-pressure cup 1, and the hollow cavity of the suction opening of the water outlet of water compensating valve 2 and exhaust-valve 3 and negative-pressure cup 1
It communicates, one end of drainage tube 4 is connect with resource of water supply, and the other end of drainage tube 4 is inserted into negative-pressure cup 1 from the bottom of negative-pressure cup 1
In hollow cavity.
In the present embodiment, the bottom of above-mentioned negative-pressure cup 1 is also installed with the outlet pipe 5 communicated with the hollow cavity of negative-pressure cup 1.
In addition, above-mentioned outlet pipe 5 can also be connected with water pump.The water inlet of water pump passes through the hollow cavity phase of outlet pipe 5 and negative-pressure cup 1
It is logical, the water in negative-pressure cup 1 is extracted out, and be promoted to head-tank or other at water.
In the present embodiment, the bottom of above-mentioned negative-pressure cup 1 is also installed with blowdown valve 6.
Above-mentioned negative-pressure cup 1, water compensating valve 2, exhaust-valve 3, drainage tube 4, outlet pipe 5, blowdown valve 6 material be stainless steel
SUS304。
In the present embodiment, above-mentioned drainage tube 4 is by argon arc welding welding in the bottom of negative-pressure cup 1.
In the present embodiment, above-mentioned outlet pipe 5 is by argon arc welding welding in the bottom of negative-pressure cup 1.
In the present embodiment, above-mentioned exhaust-valve 3, water compensating valve 2, blowdown valve 6 are connected through a screw thread to be connect with negative-pressure cup 1.
In the present embodiment, above-mentioned resource of water supply is underground tank.
It in underground tank water system, is generally drawn water using end suction centrifugal pump, or using diving water supplying pump.Using end
It is sucked away from heart pump and draws water and need to be equipped with bottom valve in suction hose low side, limit liquid in water inlet pipe and return to pond, play the function of only import but no export
Can, but bottom valve can ultimately cause water pump and take out because of cavitation problem because pool sundry blocking and mechanical wear cause bottom valve to damage
Not upper water.Using diving water supplying pump, the bottom in underground tank need to be installed on because of immersible pump, as the water body of underground tank has corruption
Corrosion will require water pump material very high.Above two water supply pattern, because bottom valve or immersible pump are installed on the bottom in pond,
Maintenance difficulty is larger, and maintenance cycle is longer, so user quite feels many worried and inconvenient in practical applications.
The working principle of the utility model is: water compensating valve 2 fills it up with diversion to negative-pressure cup 1, negative-pressure cup 1 is closed tank body,
Lower part is water in the hollow cavity of negative-pressure cup 1, and top is air；Exhaust-valve 3 makes the pressure of air in negative-pressure cup 1 with outside air
Pressure it is consistent, be not present pressure difference.When pump working, pump intake, will be in negative-pressure cup 1 by outlet pipe 5
Water extraction, and be promoted to head-tank or other at water.The air of the water level decreasing of 1 lower part of negative-pressure cup, top can occupy sky
Between become larger, atmospheric pressure becomes smaller in negative-pressure cup 1, forms pressure difference with outside air, this pressure difference overcomes the gravity of water, force
The water of underground tank enters negative-pressure cup 1 by drainage tube 4.As long as outer pressure difference including the hollow cavity memory of negative-pressure cup 1, underground
The water in pond continuous will be injected toward negative-pressure cup 1.
The utility model is mounted at the top of underground tank, and installation is simple, and maintenance is convenient.Because any loss accessory is not present,
It is not required to later maintenance management in principle.The utility model is applied in supply and drain water system, and Ordinary Centrifugal Pumps pumping can be directly used
The water of underground tank supplies water, thoroughly solve need to install bottom valve or using diving water supplying pump and bring Frequent Troubles,
A series of problems, such as maintenance difficult, high cost of investment.
