Abstract
The utility model discloses a double-water-source joint water supply device which is formed by a water supply unit A and a water supply unit B, wherein the water supply unit A and the water supply unit B jointly supply water to users, each of the water supply unit A and the water supply unit B comprises a water supply pumping set with a frequency converter for controlling, a control unit of the water supply pumping set, a water tank, an electric valve, a detecting instrument and a pressure water source pipeline, the water tanks and the pressure water source pipelines are arranged in parallel, the water tanks are used for storing water for the pressure water source pipelines, the outlets of the water tanks are provided with the electric valves, the water tanks are connected with the pressure water source pipelines after passing through the electric valves, and the detecting instruments are arranged at the positions, in front of the junctions of the electric valves and the pressure water source pipelines, of the pressure water source pipelines. The double-water-source joint water supply device has the beneficial effects that the water supply unit A and the water supply unit B are adopted to jointly supply the water to the users and can be automatically switched to each other, so that the water supply safety and reliability are greatly improved, and the device is particularly suitable for a system supplying water by two or more pressure water source pipe networks simultaneously.
Description
Technical field
The utility model relates to pressurization hydrotechny field, specifically a kind of double water source co-supplying device.
Background technology
At present, the supply equipment of prior art adopts single cover pump group or cistern water supply more, and its reliability of water supply is poor, easily, because equipment fault causes the phenomenon of cutting off the water, has influence on normal water supply.
Utility model content
The purpose of this utility model is to provide the double water source co-supplying that a kind of water supply security is good, reliability is high device.
The utility model solves the technical scheme that its technical problem adopts: double water source co-supplying device is to be made up of water supply unit A and water supply B of Unit, and combine to user and supply water by water supply unit A and water supply B of Unit, water supply unit A and water supply B of Unit comprise respectively supply-water pump group and the control module thereof with Frequency Converter Control, water tank, motor operated valve, instrumentation and pressure water source capsule road composition, and water tank and pressure water source capsule road are installed in parallel, water tank is as the amount of the reserve water in pressure water source capsule road, outlet at water tank is provided with motor operated valve, after motor operated valve, be connected with pressure water source capsule road, and be provided with instrumentation on pressure water source capsule road before motor operated valve is connected with pressure water source capsule road.
Instrumentation in water supply unit A detects when connected pressure water source capsule road is anhydrous, first open its motor operated valve, automatically switch to the way of supplying water of water tank, the water yield of being laid in by water tank provides water source for supply-water pump group and control module thereof with Frequency Converter Control, after the water yield in water tank is finished, motor operated valve cuts out and is switched to the piped water supply of pressure water source, if now pressure water source capsule road is still anhydrous, automatically starts water supply B of Unit; Equally, the instrumentation in water supply B of Unit detects that connected pressure water source capsule road is anhydrous and after quantity of water in water tank is finished, and automatically switches to water supply unit A and supplies water.After in the time that water supply unit A and water supply B of Unit are simultaneously anhydrous and separately the water yield in water tank is finished, stop supplying water.The pressure water source capsule road of water supply unit A and water supply B of Unit can connect the pipe network from two different water sources, also can connect the pipe network from same water source.Water supply unit A and water supply B of Unit be arbitrary to break down can not normal water supply time, automatically switches to by another water supply unit and supplies water.
The beneficial effects of the utility model are, the utility model adopts water supply unit A and water supply B of Unit to combine to user and supplies water, and can automatically switch mutually, thereby greatly improve water supply security, reliability, be particularly suited for the system simultaneously being supplied water by two-way or the above pressure water source capsule of two-way net.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1, water supply unit A, 2, water supply B of Unit, 3, supply-water pump group and control module thereof with Frequency Converter Control, 4, water tank, 5, motor operated valve, 6, instrumentation, 7, pressure water source capsule road, 8, user.
Detailed description of the invention
With regard to accompanying drawing 1, double water source co-supplying device of the present utility model is done to following detailed explanation below.
As shown in Figure 1, double water source co-supplying device of the present utility model is by water supply unit A(1) and water supply unit B(2) form, and by water supply unit A(1) and water supply unit B(1) combine to user (8) and supply water, water supply unit A(1) and water supply unit B(2) comprise respectively supply-water pump group and control module (3) thereof with Frequency Converter Control, water tank (4), motor operated valve (5), instrumentation (6) and pressure water source capsule road (7) composition, and water tank (4) is installed in parallel with pressure water source capsule road (7), water tank (4) is as the amount of the reserve water in pressure water source capsule road (7), be provided with motor operated valve (5) in the outlet of water tank (4), after motor operated valve (5), be connected with pressure water source capsule road (7), and be connected with pressure water source capsule road (7) at motor operated valve (5) before pressure water source capsule road (7) on be provided with instrumentation (6).
At water supply unit A(1) in instrumentation (6) detect when connected pressure water source capsule road (7) is anhydrous, first open its motor operated valve (5), automatically switch to the way of supplying water of water tank (4), the water yield of being laid in by water tank (4) is that supply-water pump group and the control module (3) thereof with Frequency Converter Control provides water source, after the water yield in water tank (4) is finished, motor operated valve (5) cuts out and is switched to pressure water source capsule road (7) and supplies water, if now pressure water source capsule road (7) are still anhydrous, automatically start water supply unit B(2); Equally, at water supply unit B(2) in instrumentation (6) detect that connected pressure water source capsule road (7) is anhydrous and the water yield is finished in water tank (4) after, automatically switch to water supply unit A(1) supply water.At water supply unit A(1) and water supply unit B(2) after when simultaneously anhydrous and separately the water yield in water tank (4) is finished, stop water supply.Water supply unit A(1) and water supply unit B(2) pressure water source capsule road (7) can connect the pipe network from two different water sources, also can connect the pipe network from same water source.Water supply unit A(1) and water supply unit B(2) both are arbitrary breaks down can not normal water supply time, automatically switch to by another water supply unit and supply water.
