Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: the end and an end that is connected user's pipe network 3 that connect city planting ductwork; Also comprise: a current stabilization jar 1; Described current stabilization jar 1 comprises: three energy-storing chamber A, water storage cavity B and air storing cavity C that the chamber is isolated mutually; Water inlet 2 on the energy-storing chamber A joins with described city planting ductwork one end that is connected; Intake-outlet 8 under delivery port 6 under the energy-storing chamber A and the water storage cavity B is to be connected to the auxilliary pump 7 of the compensation of energy-storing chamber A from water storage cavity B by a ftercompction direction; Above water storage cavity B, settle a ventilating pipe 9 to be communicated with air storing cavity C; Closing or close by float-ball type air inlet and exhaust valve 10 and electromagnetic valve 11 of described ventilating pipe 9 controlled; Delivery port 6 under the energy-storing chamber A joins by an end of booster pump or pump group 5 and barrier film jar or air pressure tank 4 and user's pipe network 3 successively;
Described water inlet 2 inserts among the energy-storing chamber A a segment length;
Having settled respectively on described energy-storing chamber A, water storage cavity B and barrier film jar or air pressure tank 4 can induction pressure, first sensor 12A, second sensor 12 and the 3rd sensor 4A of liquid level parameter.
Operating principle of the present utility model is as follows: current stabilization jar 1 has energy-storing chamber A, water storage cavity B and air storing cavity C, and three chambeies are isolated mutually.The water inlet 2 of current stabilization jar is communicated with city planting ductwork, water from city planting ductwork enters energy-storing chamber A from the water inlet 2 of current stabilization jar 1, air is compressed the top that concentrates on energy-storing chamber A among the energy-storing chamber A, because water inlet 2 inserts energy-storing chamber A one segment length, compressed air can not all be overflowed, above energy-storing chamber A, form air spring, can save the pressure oscillation that causes by a variety of causes among the pressure potential of city planting ductwork and the buffering accumulated energy chamber A.The water that comes from city planting ductwork enters water storage cavity B by the intake-outlet 8 that compensates auxilliary pump 7, water storage cavity B simultaneously, and the air among the water storage cavity B is entered air storing cavity C and stores by float-ball type air inlet and exhaust valve 10 and electromagnetic valve 11, ventilating pipe 9.Ball float is floated in water level rising up to water storage cavity B, closes float-ball type air inlet and exhaust valve 10; Or reached setting value by water level, the pressure of the 12 perception water storage cavity B of the sensor on the water storage cavity B, close electromagnetic valve 11; Or float-ball type air inlet and exhaust valve 10 and electromagnetic valve 11 are closed simultaneously.At this moment the compressed air among the air storing cavity C is in closed state, and then storing up among the water storage cavity B has expired water.Booster pump (pump group) 5 be sent to user's pipe network 3 after the delivery port 6 of the energy-storing chamber A water inlet 2 by energy-storing chamber A will laminate supercharging from the water that city planting ductwork comes, store a part of press water at barrier film jar or air pressure tank 4 simultaneously.Water supply volume minimizing when user's pipe network 3; sensor 4A sensed pressure reaches a certain setting value; booster pump 5 is shut down; keep the pressure of user's pipe networks 3 and deal with a small amount of water in user's pipe network 3 by barrier film jar or air pressure tank 4; the dischargeable capacity water yield up to clean barrier film jar of consumption or air pressure tank 4; sensor 4A sensed pressure is got back to the setting lower limit, and booster pump (pump group) 5 restarts.
When the sensor 12A perception municipal ductwork pressure on the energy-storing chamber A during near minimum water services force value, start the auxilliary pump 7 of compensation, the auxilliary pump 7 of compensation mends water among the water storage cavity B into energy-storing chamber A, the compressed air that stores among the air storing cavity C enters water storage cavity B because water storage cavity B middle water level descends, make pressure reduction among the water storage cavity B, pressure among the energy-storing chamber A raises, and city planting ductwork reduces the water yield that enters energy-storing chamber A; Booster pump (pump group) 5 is continued to laminate pressurized water supply to user's pipe network 3, and wherein a part is from water storage cavity B, and another part is from city planting ductwork.Because reduced the water supply of city planting ductwork, the pressure of city planting ductwork no longer descends.Because the metered flow of the auxilliary pump 7 of compensation generally has only some/one of booster pump 5 metered flows; moisture storage capacity among the water storage cavity B can be kept the output of several times; go over up to the not enough period of of short duration pressure of supply water; the auxilliary pump 7 of compensation is shut down; water storage cavity B stores up full water again, prepares the not enough period of the next of short duration pressure of supply water of reply.
For the water storage among the water storage cavity B that keeps current stabilization jar 1 fresh, the situation of of short duration pressure of supply water deficiency even do not take place in (such as 24 hours) in setting-up time, also to regularly start the auxilliary pump 7 of compensation, extract the water storage among the water storage cavity B out, change the water that comes of the fresh city planting ductwork of storage.
