Abstract
The utility model discloses a no air pollution self -balancing does not have negative pressure water supply equipment, including gasbag, air pump, water supply pipe, a pressure sensor, the 2nd pressure sensor, the 3rd pressure sensor, water pump, controller, the utility model discloses a no air pollution self -balancing does not have negative pressure water supply equipment can guarantee the pressure invariant that supplies water to simple structure, water supply pressure stability, intelligent degree is high, and can not receive the pollution of air.
Description
Technical field
The utility model relates to supply equipment technical field, is specifically related to a kind of without air pollution self-balancing non-negative pressure water-supply installation.
Background technology
In the production, living water use process of all kinds of building daily life water, all kinds of industrial and mining enterprises, when often occurring that water supply volume increases, the phenomenon that hydraulic pressure reduces, although the supply equipment kind used in existing regional water supply is also a lot, but the hydraulic pressure of existing supply equipment is negative correlation with the quantity of use water, when using water number amount various flow large, hydraulic pressure can diminish accordingly., when, just often there is the phenomenon that high-rise buildings hydraulic pressure is very low in the community user that such as floor is higher the water use peak time period in the evening at noon, time serious, the very little impact of water yield uses water normally, and few once water supply volume, then hydraulic pressure can increase suddenly, causes pipe network to damage sometimes.
In order to solve negative pressure problem, in water supply line, easily mix air, and often with dusty gas in air.
Utility model content
The technical problems to be solved in the utility model: supply water even if existing part supply equipment cannot realize constant-pressure variable or achieve constant-pressure variable water supply but device structure complexity, pressure of supply water is still stable not.
In order to solve above technical problem, the technical solution of the utility model is as follows: without air pollution self-balancing non-negative pressure water-supply installation, comprises air bag, air pump, water supply line, the first pressure sensor, the second pressure sensor, the 3rd pressure sensor, water pump, controller;
The gas outlet of air pump connects the air inlet port of air bag;
Tube wall between the water inlet of water supply line and delivery port is provided with air inlet port;
The gas outlet of air bag connects the air inlet port of water supply line, and is provided with air filter between the gas outlet of air bag and the air inlet port of water supply line;
The inside of air bag is provided with the 3rd pressure sensor;
First pressure sensor is arranged at the water outlet of water supply line;
The delivery port of water supply line connects the water inlet of water pump;
The water outlet of water pump is provided with the second pressure sensor;
The IO port of the signal output part difference connection control device of the first pressure sensor, the second pressure sensor, the 3rd pressure sensor;
Controller controls the start and stop of air pump.
Further, described controller adopts AT89S51 single-chip microcomputer.
Compared with prior art, the beneficial effects of the utility model: of the present utility model can assure feed water constant pressure without air pollution self-balancing non-negative pressure water-supply installation, and structure is simple, and pressure of supply water is stablized, and intelligence degree is high; And the pollution of air can not be subject to.
Accompanying drawing explanation
Fig. 1 is the utility model principle block diagram;
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1: without without air pollution self-balancing non-negative pressure water-supply installation, comprise air bag, air pump, water supply line, the first pressure sensor, the second pressure sensor, the 3rd pressure sensor, water pump, controller; The gas outlet of air pump connects the air inlet port of air bag; Tube wall between the water inlet of water supply line and delivery port is provided with air inlet port; The gas outlet of air bag connects the air inlet port of water supply line, and is provided with air filter between the gas outlet of air bag and the air inlet port of water supply line; The inside of air bag is provided with the 3rd pressure sensor;
First pressure sensor is arranged at the water outlet of water supply line; The delivery port of water supply line connects the water inlet of water pump; The water outlet of water pump is provided with the second pressure sensor;
The IO port of the signal output part difference connection control device of the first pressure sensor, the second pressure sensor, the 3rd pressure sensor; Controller controls the start and stop of air pump.
Wherein, controller adopts AT89S51 single-chip microcomputer.
Utility model works principle: know current normal discharge pressure according to the first pressure sensor, the pressure difference value size of the two is calculated again according to the data of the second pressure sensor, controller controls air pump and carries out pressure compensation, according to the difference of the first pressure sensor and the second pressure sensor, controller can know that whether pressure compensation is suitable in real time; 3rd pressure sensor moment detected the pressure in air bag, and the numerical value that controller detects according to the 3rd pressure sensor judges whether start and stop air pump.
Owing to being provided with air filter between air bag and water supply line, thus guarantee that water supply can not by air pollution.
Claims (2)
1. without air pollution self-balancing non-negative pressure water-supply installation, it is characterized in that, comprise air bag, air pump, water supply line, the first pressure sensor, the second pressure sensor, the 3rd pressure sensor, water pump, controller;
