Description
Technical field
This utility model relates to supply equipment field, is specifically related to a kind of non-negative pressure frequency-changing water supply device.
Background technology
Non-negative-pressure variable frequency constant pressure water supply equipment is a kind of novel sanitation and hygiene, energy-efficient supply equipment, is also called pipe network Pressure-superposed water supply equipment by industry. This equipment is full-enclosed structure, it is not necessary to build any type of pond, it is to avoid water supply secondary pollution. Traditional pot type non-negative pressure water-supply installation is to cut off municipal water supply, stoppage in transit water pump to avoid the formation of negative pressure in city planting ductwork, not only reduce the service life of water pump and valve, and municipal ductwork pressure fluctuation can be caused relatively big, affect the operation safety of periphery user and pipe network. The water supply of user is completely dependent on water pump, and low discharge supplied water and still needed to start water pump night, added energy consumption.
Summary of the invention
In order to solve above-mentioned technical problem, content of the present utility model aims to provide a kind of non-negative pressure frequency-changing water supply device that can carry out suitably switching when the different water yields require. The technical solution of the utility model is: a kind of non-negative pressure frequency-changing water supply device, including municipal administration water pipe, vacuum tank, force (forcing) pump, switch board and user interface, it is characterised in that: 2 parallel baffles are set inside described vacuum tank, inside vacuum tank, include 1 areas of permanent pressure and 2 higher-pressure regions, liquid-level switch it is set bottom vacuum tank and cleans discharge outlet, between vacuum tank and user interface, being connected to inlet gage and electromagnetic valve; It is attached by butterfly valve, check-valves, filter, disinfector and flow controller between described municipal administration water pipe and vacuum tank; Described force (forcing) pump is connected between vacuum tank and user interface, is provided with damping check valve between force (forcing) pump and user interface, is connected diaphragm-type air-compressed tank and pressure transducer between damping check valve with user interface; Described switch board connects liquid-level switch, switch board Bonding pressure sensor, and switch board connects force (forcing) pump, and switch board connects inlet gage; It is connected to motor-operated control valve between described user interface and vacuum tank.
Further, the quantity of described force (forcing) pump is at least 2, and is parallel relationship.
Beneficial effect:
This utility model flow controller instead of the air partition device in conventional art, and tank body is divided into height, areas of permanent pressure, is controlled the flow supply in constant voltage chamber by flow controller, it is ensured that low discharge supplies, it is to avoid water pump frequently opens and closes.
This utility model can apply municipal ductwork pressure effectively, and energy consumption is relatively low.
