Description
Technical field
The utility model belongs to water system field, relates in particular to a kind of outdoor laminating water supply equipment.
Background technology
Laminating water supply equipment directly absorbs water from water supply network, by pressure sensor, detect pressure, detected value and setting value are compared, calculate and on the basis of original pressure of municipal tap water pipe network, need the force value that increases, determine that water pump drops into number of units and frequency converter output frequency, adjust the rotating speed of water pump and realize constant pressure water supply or variable-pressure water supply to meet water curve.Laminating water supply equipment has at utmost utilized the former water pressure of city planting ductwork tap water, and city planting ductwork is not produced to negative pressure, closed operation, and ingress of air, has not reduced the secondary pollution of water, is the energy-conserving product in water supply of new generation field.But current outdoor laminating water supply equipment is complex structure mostly, produce, maintenance cost is all higher, for example Chinese patent ZL201020541545.0 discloses a kind of type non-negative pressure water-supply installation that directly laminates, comprise water inlet pipe, inlet pressure gauge, backflow preventer, Hand-operated butterfly valve, electric butterfly valve, bypass line, water pump, outlet pipe, it is characterized in that: the rear end of water inlet pipe is also connected to a bypass line, bypass line connects outlet pipe, the rear termination of water inlet pipe is by inlet pressure gauge, backflow preventer, Hand-operated butterfly valve, the negative pressure preventing module that electric butterfly valve forms is the front end of water pump again, the rear end connected water outlet pipe of water pump.It is characterized in that: inlet pressure gauge is arranged on water inlet pipe, backflow preventer, Hand-operated butterfly valve, electric butterfly valve are connected according to this.The supply equipment of this structure is complex structure not only, manufactures maintenance cost high, because pipeline is complicated, often occurs damaging, and product result of use is not good yet.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of compact conformation, low cost of manufacture, the outdoor laminating water supply equipment that result of use is good, comprise casing, in described casing, be provided with a cavity, cavity internal upper part is provided with a frequency-conversion control cabinet, it is characterized in that: described frequency-conversion control cabinet below is provided with inlet channel, outlet conduit, water pump, on described inlet channel, be disposed with butterfly valve A, A is flexible coupling, backflow preventer, pressure transmitter A, on described outlet conduit, be disposed with electro connecting pressure gauge, air pressure tank, pressure transmitter B, B is flexible coupling, butterfly valve B, described inlet channel, outlet conduit connects by water pump.
The quantity of described water pump is more than 2 or 2.
The quantity of described water pump is 2.
The beneficial effects of the utility model are:
1, compact overall structure, floor space are little
Equipment adopts global design, only need to connect water inlet pipe and water outlet pipe and power supply just can have been used, and can be arranged on outdoorly, and without pump house, floor space is little.
2, do not produce negative pressure
This equipment directly absorbs water to laminate with municipal tap water pipe network and supplies water and do not cause city planting ductwork to occur negative pressure.
3, automaticity is high
Owing to increasing the setting of water pump, when the numerical value of pressure transmitter A is less than 1.5MP, water pump is opened automatically, and when the numerical value of pressure transmitter B is greater than 2MP, water pump cuts out automatically, and automatic synchronization ability is strong.
4, install, safeguard simple and fast
On-the-spot need assemble large of equipment, connects inlet tube and outlet tube, and short construction period is installed simple.

Below in conjunction with accompanying drawing, the utility model is described further:
In figure: 1-casing, 2-frequency-conversion control cabinet, 3-cavity, 4-butterfly valve A, the 5-A that is flexible coupling, 6-backflow preventer, 7-water pump, 8-pressure transmitter A, 9-inlet channel, 10-electro connecting pressure gauge, 11-outlet conduit, 12-air pressure tank, 13-pressure transmitter B, the 14-B that is flexible coupling, 15-butterfly valve B.
Embodiment:
The present embodiment comprises casing 1, in casing 1, be provided with a cavity 3, cavity 3 internal upper parts are provided with a frequency-conversion control cabinet 2, frequency-conversion control cabinet 2 belows are provided with inlet channel 9, outlet conduit 11, water pump 7, on inlet channel 9, be disposed with butterfly valve A4, A5 is flexible coupling, backflow preventer 6, pressure transmitter A8, on outlet conduit 11, be disposed with electro connecting pressure gauge 10, air pressure tank 12, pressure transmitter B13, B14 is flexible coupling, butterfly valve B15, inlet channel 9, outlet conduit 11 connects by water pump 7, the quantity of water pump 7 is more than 2 or 2, the present embodiment be take 2 as example.
Owing to increasing the setting of water pump 7, when the numerical value of pressure transmitter A8 is less than 1.5MP, water pump 7 is opened automatically, and when the numerical value of pressure transmitter B13 is greater than 2MP, water pump 7 cuts out automatically, and automatic synchronization ability is strong.
Utilize technical scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designs similar technical scheme, and reaching above-mentioned technique effect, is all to fall into protection domain of the present utility model.
