Abstract

Disclosed is a linkage device which is shared by a non-negative pressure water supply equipment and a water pool and comprises a municipal water intake pipe, a non-negative pressure steady current tank, a pressure sensor, a control cabinet and a water supply main pipe. A normally open electric valve is arranged on the municipal water intake pipe; one way of the electric valve is connected into the non-negative pressure steady current tank, the other way is connected into the water pool; a water outlet of the water pool is connected with the non-negative pressure steady current tank through a connecting pipe which is provided with a normally closed electric valve; and the non-negative pressure steady current tank is connected with the water supply main pipe through a turbocharged pump unit. The linkage device shared by the non-negative pressure water supply equipment and the water pool is designed according to a domestic water supply mode of units, schools, residential districts and high-rise buildings that the flow and the pressure of a municipal pipe network are sufficient in normal time, but the flow and the lift are low in water using peak period; the shared linkage device not only can be used in a new architectural design, but also can be reformed and selected by original users supplied with water through secondary pressing of the water pool; the linkage device saves the energy and protects the environment, and solves the problem of energy saving and consumption reduction for the users requiring a large amount of water, particularly for institutions and universities, armies and the like.

Description

No-negative-pressure water supply equipment and pond common linkage device

Technical field

The utility model relates to a kind of no-negative-pressure water supply equipment and pond common linkage device.

Background technology

No-negative-pressure water supply equipment significantly reaches with its energy-saving effect and keeps the original hygienic quality safety in municipal tap water not to be subjected to secondary pollution, reduces advantage such as equipment investment, obtains the approval and the welcome in market rapidly.But it is with good conditionsi using this no-negative-pressure water supply equipment; area in city planting ductwork flow, insufficient pressure can not be installed; and the municipal water supply network segment that has flow, pressure all can satisfy water supply requirement at ordinary times; only reduce at the reduction of peak water period ductwork pressure, flow; no negative pressure equipment can not work on, and has to shut down, and uses the water tank second pressure water supply instead; this just needs to install a cover water pump assembly again and takes over the peak water supply of non-negative pressure water supply system, increases equipment investment.The former unit that has utilized the pressurization of water tank secondary, especially universities and colleges, water supply volume is big, and the water time concentrates, and number average adopts storage-type second pressure water supply mode mostly, after having the tap water of pressure to put into water tank the municipal administration, pressure has become zero, and the energy wastes, and the tap water with former antiseptic hygiene is subjected to secondary pollution in the process that stores through water tank and pressurize again, this second pressure water supply is though be variable frequency control energy consumption or sizable.

Summary of the invention

The purpose of this utility model is exactly at city planting ductwork flow, pressure abundance at ordinary times, and water use peak period flow, unit, school, residential quarters and tall building life water supply modes that lift is on the low side provide a kind of no-negative-pressure water supply equipment and pond common linkage device of energy-saving and environmental protection.

No-negative-pressure water supply equipment of the present utility model and pond common linkage device, comprise municipal water inlet pipe, non-negative pressure stabilized jar, pressure sensor, the booster water pump unit, switch board and water main, be equipped with on the municipal administration water inlet pipe and often drive motor operated valve, after threeway, one the road inserts non-negative pressure stabilized jar, the pond is inserted on another road, the pond water inlet is provided with float valve, the delivery port in pond joins by tube connector and non-negative pressure stabilized jar, normally closed motor operated valve is installed on this tube connector, non-negative pressure stabilized jar is passed through the booster water pump unit and is connected with water main, water level switch also is housed in the pond, on non-negative pressure stabilized jar pressure sensor is housed, often drives motor operated valve, normally closed motor operated valve, pressure sensor, water level switch and booster water pump unit all link to each other with switch board by lead.

No-negative-pressure water supply equipment of the present utility model and pond common linkage device operating principle are: municipal water one tunnel is often driven motor operated valve and is flowed in the pond, and when the supreme water level of pond fills with water, float valve is closed, and it is stand-by that full water is held in the pond; Another road is often driven motor operated valve and is entered (municipal pipe pressure feedwater, uninterrupted) in non-negative pressure stabilized jar, is conducted to the user by water main again after the pressurization of booster water pump unit.When water use peak arrives, municipal ductwork pressure reduces, inflow-rate of water turbine reduces, when pressure is low to moderate certain setting value (as 0.10Mpa), the switch board control system receives behind the signal of pressure sensor immediately feedback and sends instruction, order is often driven motor operated valve and is closed, and normally closed motor operated valve is opened, and both move simultaneously, the deposit water in pond enters in non-negative pressure stabilized jar by tube connector, the booster water pump unit is pressed switch board instruction and is continued operation, general about 2 hours to 3 hours of peak period water, rise in peak municipal ductwork pressure later, flow increases, when pressure rose to setting value, switch board can make again and often hold the motor operated valve unlatching, normally closed motor operated valve cuts out, and recovers non-negative pressure water supply.When the water of peak, also can adopt another kind of way of supplying water, pond water storage volume is little or the peak water supply volume is big, this drives motor operated valve often and does not close, and still water inlet is just opened normally closed motor operated valve to non-negative pressure stabilized jar and pond, allow tank water replenish, fill up the peak flow deficiency, the pond still has water to replenish like this, equipment is pressed peak flow and is supplied water, water supply time can increase, and after the peak, pressure recovers just often just to close motor operated valve, the recovery city planting ductwork supplies water, and no negative pressure equipment normally moves.In order to prevent the pond in lack of water or when anhydrous, water level switch is installed in the water pump assembly damage that works on hereby in the pond, and when being controlled at lowest water level, water pump assembly is shut down, and guarantees unit safety.

No-negative-pressure water supply equipment of the present utility model and pond common linkage device, at city planting ductwork flow, pressure abundance at ordinary times, and water use peak period flow, unit, school, residential quarters and tall building life water supply modes that lift is on the low side and design, this common linkage device not only new building design can adopt, the water supply user of some former millpond (water tank) secondary pressurizations also can transform and implement to select for use, its energy-saving and environmental protection, for energy-conservation consumption reduction such as water rich and influential family, especially universities and colleges, army etc. has solved a difficult problem.
