Abstract

The utility model relates to a water supply device in a water supply system, in particular to a non-negative-pressure variable frequency water supply device directly connected to pipeline networks of tap water. A gate valve, a reflux valve, a steady-flow tank, a pressure gage, a water pump stabilized pressure pump set, a pressure gage set and a water outlet pipe opening are sequentially connected, a vacuum check valve is arranged above the steady-flow tank, a pressure tank is arranged in the middle of the pressure gage set, and the pressure gage, the pressure gage set and the water pump stabilized pressure pump set are connected to a control cabinet. The non-negative-pressure variable frequency water supply device has the advantages that any side effect is not exerted on the pipeline networks of tap water.

Description

The non-negative pressure frequency-changing water supply device being directly connected with tap water pipe network
Technical field
This patent relates to the supply equipment in water system, is specially a kind of non-negative pressure frequency-changing water supply device being directly connected with tap water pipe network.
Background technology
Traditional way of supplying water be unable to do without reservoir, water in reservoir is generally supplied by tap water pipe network, like this, pressure in tap water pipe network enters into behind pond, become as zero pressure, cause a large amount of wastes of the energy, simultaneously, because reservoir is open, easily cause secondary pollution and the artificial destruction at water source.
Summary of the invention
This patent is for above-mentioned problem, and in order to respond energy-saving and emission-reduction and people to healthy pursuit, we,, to being a kind ofly directly connected with tap water pipe network of developing on the basis of frequency-changing pressure stabilizing water supply facilities, do not produce a complete set of equipment of any side effect to tap water pipe network.
The non-negative pressure frequency-changing water supply device being directly connected with tap water pipe network, by gate valve, reflux valve, steady-flow tank, pressure meter, water pump, stabilized pressure pump group, pressure meter group, air pressure tank, effluent pipe mouth, vacuum check valve, switch board, formed, it is characterized in that: gate valve, reflux valve, steady-flow tank, pressure meter, water-pump voltage-stabilization pump group, pressure meter group, effluent pipe mouth connect successively, steady-flow tank top arranges a vacuum check valve, in the middle of pressure meter group, an air pressure tank is set, pressure meter, pressure meter group, water-pump voltage-stabilization pump group are connected to switch board.
After equipment installation, the water in tap water pipe network enters steady-flow tank, and in tank, air is from vacuum check valve investigation, and after water is full of, vacuum check valve cuts out automatically.
In tap water pipe network, water pressure energy meets while using water condition, and equipment is not worked.
In tap water pipe network, discharge is lower than pump capacity, hydraulic pressure can not meet water hydraulic pressure, system pressure signal feeds back to switch board by distance-transmission pressure gauge, switch board orders about water-pump voltage-stabilization pump group and starts working, and according to the size of the water yield, automatically regulate pump operation speed, to realize the constant pressure water supply of pipe network.
Electro connecting pressure gauge in steady-flow tank is lower than setting pressure; this equipment autostop; vacuum check valve on steady-flow tank, if tap water pipe network flow is less than pump capacity, the water in vacuum tank as a supplement water source still can normal water supply; minimizing along with the water yield in tank; air enters steady-flow tank by vacuum check valve, and in tank, vacuum is destroyed, and guarantees that tap water pipe network is unaffected; unidirectional reflux valve can prevent that pipeline internal medium water from refluxing, not contaminated to guarantee water source.
This patent makes full use of the pressure potential that municipal water resource has itself, in line with poor how many principles of mending how many points, effective, has brought into play to greatest extent the energy-saving effect of frequency control, has significantly reduced operating cost; Non-negative-pressure variable frequency water supply facilities is complete sets of products owing to dispatching from the factory, therefore only need when mounted directly access pipe network to import and export and can use, owing to being directly connected with urban pipe network, does not need to build pond, water tower, only needs to be equipped with a steady-flow tank; Due to the airtight constant pressure water supply of canyon, kept the water sanitary standard of municipal water sources completely, can not contact with extraneous air or material, cause secondary pollution or the artificial destruction of water quality; This equipment adopts Automatic Control, and airtight operation, without cleaning, sterilize constant pitch less manpower.
Beneficial effect, advantage: energy-efficient; Simple installation, saving floor space; Safety and sanitation; The cycle of operation is long, and cost is low, can replace reservoir or high level cistern, and the pressure that can make full use of tap water pipe network directly supplies water or water relay, and guarantees that water quality is not contaminated, clean, safety, health.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent:
Wherein: 1---gate valve; 2---reflux valve; 3---steady-flow tank; 4---pressure meter; 5---water pump, stabilized pressure pump group; 6---pressure meter group; 7---air pressure tank; 8---effluent pipe mouth; 9---vacuum killer tube; 10---switch board.
The specific embodiment
Below in conjunction with the specific embodiment, this patent is described further.
The non-negative pressure frequency-changing water supply device being directly connected with tap water pipe network, by gate valve, reflux valve, steady-flow tank, pressure meter, water pump, stabilized pressure pump group, pressure meter group, air pressure tank, effluent pipe mouth, vacuum check valve, switch board, formed, gate valve, reflux valve, steady-flow tank, pressure meter, water-pump voltage-stabilization pump group, pressure meter group, effluent pipe mouth connect successively, steady-flow tank top arranges a vacuum check valve, in the middle of pressure meter group, an air pressure tank is set, pressure meter, pressure meter group, water-pump voltage-stabilization pump group are connected to switch board.
After equipment installation, the water in tap water pipe network enters steady-flow tank, and in tank, air is from vacuum check valve investigation, and after water is full of, vacuum check valve cuts out automatically.In tap water pipe network, discharge is lower than pump capacity, hydraulic pressure can not meet water hydraulic pressure, system pressure signal feeds back to switch board by distance-transmission pressure gauge, switch board orders about water-pump voltage-stabilization pump group and starts working, and according to the size of the water yield, automatically regulate pump operation speed, to realize the constant pressure water supply of pipe network.
