Abstract
The utility model discloses a no negative pressure variable frequency water supply device, first ball valve, water pump, check valve, variable frequency control device and second ball valve including connecting gradually are equipped with unfamiliar atmospheric pressure jar and pressure sensor on the delivery pipe between second ball valve and the check valve, pressure sensor inserts the variable frequency control device input, and the variable frequency control device output is connected with the water pump. Compared with the prior art, the utility model discloses convenient to detach, specially for the low discharge user makes to measure, not only pressure is invariable, and energy -conserving, environmental protection moreover can not produce the negative pressure to municipal pipeline, can not influence neighbours' water.
Description
Technical field
The utility model relates to secondary water-supply technical field, is specifically related to a kind of non-negative pressure frequency conversion water supply facility.
Background technology
It is take city planting ductwork as water source that non-negative-pressure variable frequency supplies water, utilize the original pressure of city planting ductwork, form airtight continuous relay supercharging way of supplying water, non-negative pressure frequency-changing water supply device is development and the extension of constant pressure water supply equipment, can directly be connected with tap water pipe network, any side effect can not be produced to tap water pipe network, and be directly laminate water supply on the basis of municipal ductwork pressure, but, tradition non-negative pressure frequency-changing water supply device is applied to traditional villa, when the low discharges such as factory supply water, there is pressure transient, noise at night is large, many drawbacks such as power wastage, and select large-scale without negative pressure secondary supply equipment for low discharge supply water there is low load with strong power, equipment waste, invest excessive phenomenon.
As can be seen here, when traditional non-negative pressure frequency-changing water supply device is applied to Small-flow user, unstable by water pressure, power consumption is high, can produce influence each other between neighbourhood with water.
Utility model content
The purpose of this utility model is to provide a kind of constant pressure, is convenient to dismounting, and energy-saving and environmental protection, negative pressure can not be produced to municipal pipeline, the non-negative pressure frequency conversion water supply facility of neighbours' water can not be affected.
For achieving the above object, the utility model provides following technical scheme:
A kind of non-negative pressure frequency conversion water supply facility, comprise the first ball valve, water pump, flap valve, frequency-converting control device and the second ball valve that connect successively, feed pipe between described second ball valve and flap valve is provided with diaphragm air pressure tank and pressure sensor, described pressure sensor is connected with frequency-converting control device input, and described frequency-converting control device output is connected with water pump.
As further program of the utility model: described diaphragm air pressure tank capacity is 8L.
As further program of the utility model: when outlet conduit does not have pressure to change, described water pump is stopped operating by frequency-converting control device time delay 1-99 (time is adjustable) second.
As further program of the utility model: when outlet conduit pressure reduces 0.05MPa, described starting mode of pump.
As further program of the utility model: after water pump reaches rated speed, still can not arrive and normally use pressure, described water pump underdrive immediately.
Compared with prior art, the beneficial effects of the utility model are: be convenient to dismounting, aim at Small-flow user and make to measure, not only constant pressure, and energy-saving and environmental protection, can not produce negative pressure, can not affect neighbours' water to municipal pipeline.
Accompanying drawing explanation
Fig. 1 is non-negative pressure frequency conversion water supply facility schematic diagram.
In figure: 1, water pump; 2, the first ball valve; 3, flap valve; 4, diaphragm air pressure tank; 5, pressure sensor; 6, frequency-converting control device; 7, the second ball valve.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
A kind of non-negative pressure frequency conversion water supply facility, comprise the first ball valve 2, water pump 1, flap valve 3, frequency-converting control device 6 and the second ball valve 7 that connect successively, feed pipe between described second ball valve 7 and flap valve 3 is provided with diaphragm air pressure tank 4 and pressure sensor 5, described pressure sensor 5 is connected with frequency-converting control device 6 input, and described frequency-converting control device 6 output is connected with water pump 1.
Utility model works principle: water pump 1 water inlet is provided with ball valve 2, water pump 1 delivery port is provided with flap valve 3, water pump 1 delivery port is connected with diaphragm air pressure tank 4 by outlet pipe, diaphragm air pressure tank 4 is 8L-50L, outlet pipe is provided with pressure sensor 5, pressure sensor 5 accesses frequency-converting control device 6 input, in frequency-converting control device 6 output access water pump 1, water inlet is controlled at the water inlet mounting ball valve 2 of water pump 1, and be convenient to dismounting, water pump 1 delivery port is provided with flap valve 3, during when minimum flow water or without water, flap valve 3 cuts out, ensure that the water in diaphragm air pressure tank 4 does not flow backwards, now, the pressure sensor 5 be arranged on outlet conduit detects that pipeline does not have pressure to change, this signal is passed to frequency-converting control device 6, frequency-converting control device 6 was by time delay 3 seconds, judge, when certain water electrode is few or without water, just water pump 1 is stopped to rotate, water pump 1 is made to enter resting state, when user starts with water, when pipeline pressure reduces 0.05MPa, system sends signal, water pump 1 starts, then pressure reaches normal value, thus maintain permanent hydraulic water, after water pump reaches rated speed, still can not arrive and normally use pressure, controller will judge municipal pipeline insufficient water, immediately underdrive, prevent negative pressure, affect neighbours' water.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
